LAM RESEARCH HTAA-16W-A DC Power Supply Replacement Module

Product Overview

LAM RESEARCH HTAA-16W-A DC Power Supply Replacement Module

The LAM RESEARCH HTAA-16W-A is a 5VDC, 16W DC power supply module originally designed for Lam Research semiconductor fabrication equipment. Cross-referenced under part numbers 853-017505-001-B, 90X0077, DM-3S12/ZN, and 543-12310-00-5, this module serves as a direct, drop-in replacement for aging or failed power supply assemblies in Lam Research etch, CVD, and process chamber control systems. Whether your facility is managing a planned upgrade or responding to an unplanned failure, TOPNLMS maintains verified stock of this module to support rapid restoration of production continuity.

Semiconductor fabrication environments demand power supply components that deliver stable, low-ripple DC output under continuous load. The HTAA-16W-A is engineered to meet these demands, providing regulated 5VDC at up to 16W to logic boards, I/O interface cards, and control electronics within Lam Research process equipment. Its compact form factor and standardized connector footprint allow it to replace the original unit without modification to the host chassis, wiring harness, or mounting hardware — a critical advantage when minimizing equipment downtime is the primary objective.

Seamless Upgrade Solutions

A power supply failure in semiconductor fab equipment rarely occurs in isolation. When replacing the HTAA-16W-A, maintenance engineers frequently find it necessary to inspect or simultaneously replace adjacent components that share the same power rail or control bus. In Lam Research etch and CVD systems, the 5VDC rail supplied by this module typically powers the I/O interface board and process controller logic card mounted within the same equipment chassis. If these boards show signs of voltage stress or intermittent faults, sourcing them alongside the power supply module reduces the risk of repeat downtime.

For facilities managing a broader equipment refresh, the HTAA-16W-A is commonly replaced as part of a coordinated upgrade that also addresses the 24VDC auxiliary power supply serving solenoid valves and actuator drivers, as well as the RF match network control board that governs plasma process stability. In multi-chamber fab environments, it is standard practice to replace power supply modules across all chambers simultaneously to normalize the maintenance cycle and reduce the probability of staggered failures.

When the replacement is part of a system-level migration — for example, transitioning from an older Lam Research 2300 series platform to a modernized control architecture — engineers must also evaluate the chamber controller backplane, analog I/O signal conditioning modules, and interlock relay assemblies for compatibility with the updated power distribution scheme. The HTAA-16W-A’s standard 5VDC output ensures it integrates without issue into both legacy and upgraded control architectures.

For facilities operating mixed-generation equipment, TOPNLMS also stocks related Lam Research power assemblies including 12VDC and 24VDC chassis power modules, EMI filter assemblies for the AC input stage, and fuse and circuit protection boards that protect downstream logic from transient events. Procuring these components from a single verified source simplifies incoming inspection, documentation, and warranty administration.

Retrofit Guidance FAQ

Q1: Does the HTAA-16W-A require any wiring changes during installation?
No. The HTAA-16W-A is a direct pin-compatible replacement for the original Lam Research power supply modules cross-referenced under 853-017505-001-B, 90X0077, DM-3S12/ZN, and 543-12310-00-5. The connector footprint, mounting hole pattern, and output voltage are identical to the original specification. No wiring modification, adapter harness, or chassis rework is required. Technicians can complete the swap using standard ESD-safe procedures without altering any other system component.

Q2: Is the HTAA-16W-A compatible with both older and newer Lam Research equipment generations?
Yes. The 5VDC / 16W output specification is a long-standing standard across multiple generations of Lam Research process equipment. The HTAA-16W-A is compatible with etch, CVD, and related process chamber control electronics that originally used the referenced part numbers. If your equipment uses a different output voltage or power rating, contact TOPNLMS with your full equipment model and original part number for cross-reference verification before ordering.

Q3: Has the module been tested before shipment?
Yes. Every HTAA-16W-A unit shipped by TOPNLMS undergoes pre-shipment functional testing, including output voltage verification under load, ripple measurement, and visual inspection for physical damage. Units that do not meet specification are quarantined and not offered for sale. A test record is available upon request for quality documentation purposes.

Q4: What happens if the module fails within the warranty period?
TOPNLMS provides a 12-month warranty covering manufacturing defects and functional failures under normal operating conditions. In the event of a warranty claim, contact [email protected] with your order reference and a description of the fault. TOPNLMS will arrange a replacement or repair at no additional cost. Response time for warranty cases is typically within one business day.

Warranty Assurance

TOPNLMS backs every HTAA-16W-A shipment with a 12-month warranty from the date of delivery. This warranty covers functional failures attributable to manufacturing defects, component quality, or workmanship. It does not cover damage resulting from incorrect installation, overvoltage events, or physical mishandling after delivery.

Prior to shipment, each unit is subjected to a structured pre-delivery inspection protocol: output voltage and current are verified under rated load, ripple and noise are measured against specification, and the physical condition of connectors, housing, and labeling is confirmed. Units are packed in anti-static packaging with appropriate cushioning to prevent transit damage.

For procurement teams requiring documentation, TOPNLMS can provide a certificate of conformance, test report, and packing list with each shipment. Lead times for in-stock units are typically 3–7 business days for international express delivery. For urgent requirements, expedited shipping options are available — contact the sales team directly to confirm availability and arrange priority dispatch.

Long-term supply continuity is a core commitment at TOPNLMS. For facilities that require ongoing access to the HTAA-16W-A or related Lam Research power supply components, TOPNLMS offers reserved stock arrangements and scheduled replenishment programs to ensure that critical spare parts are available when needed, without the lead time uncertainty associated with spot-market procurement.
