Compatible Replacement & Equivalent Models
The following models are commonly evaluated as functional replacements or equivalents for the XVME-531. Compatibility depends on your chassis, backplane, and load requirements — always validate before deployment.
- XYCOM XVME-530 – Earlier revision in the same XVME power supply family; verify output ratings
- XYCOM XVME-532 – Higher-output variant; suitable if load demands have increased
- Elbit / Curtiss-Wright VPX/VME PSU series – Successor product lines from the acquiring entity
- Acromag VME Power Supplies – Third-party VMEbus PSU with compatible rail outputs
- Wiener / ISEG VME Power Supplies – Industry-standard VME chassis power solutions
- Emerson / Artesyn VME PSU modules – Widely used in legacy VME system upgrades
Cross-reference is provided for engineering evaluation only. Konmask.com does not guarantee drop-in compatibility without application review.
Why Choose the Original Model
- Exact form-factor fit – No chassis modification required for existing XYCOM VME racks
- Validated backplane compatibility – Designed and tested against XYCOM VME chassis specifications
- Minimized re-qualification risk – Critical in regulated industries (defense, aerospace, rail)
- Proven field reliability – Long-running installed base with documented MTBF data
- Spare parts continuity – Maintains system homogeneity for multi-unit installations
Typical Applications
- Industrial automation and process control systems
- Defense and aerospace embedded computing platforms
- Test & measurement VME chassis
- Legacy SCADA and DCS backplane power distribution
- Telecommunications and signal processing racks
- Research and laboratory VMEbus instrumentation
System Compatibility
The XVME-531 is designed for use within VMEbus (IEEE 1014) compliant chassis. Verify the following before installation:
- Chassis slot pitch and card guide dimensions match single-slot VME form factor
- Backplane P1/P2 connector pinout is standard VME (not proprietary variant)
- Total system load (all installed boards) does not exceed PSU rated output per rail
- Chassis airflow and cooling are adequate for the PSU’s thermal dissipation
- Input AC supply voltage and frequency fall within the module’s universal input range
Selection Guide
Use the following criteria to determine whether the XVME-531 or an alternative is the right choice for your application:
- Exact replacement needed (same chassis, same slot): Source an original XVME-531 — Konmask.com stocks verified units
- Higher load requirements: Evaluate XVME-532 or equivalent higher-wattage VME PSU
- System migration / modernization: Consider Curtiss-Wright or Elbit successor PSU with adapter bracket
- Budget-sensitive MRO: Evaluate Acromag or Wiener third-party VME PSU with equivalent rail specs
- Regulated / certified environment: Original OEM part strongly recommended to preserve system certification
Quality Assurance & Sourcing

Replacement & Compatibility FAQ
Q: Is the XVME-531 still in production?
A: XYCOM’s VME product line has been discontinued under the original brand. Konmask.com sources verified new-old-stock and refurbished units to support legacy system maintenance.
Q: Can I use a third-party VME PSU as a direct replacement?
A: Functionally possible if rail voltages, current ratings, and connector pinout match. However, in certified or regulated systems, substitution may require re-qualification. Consult your system integrator.
Q: What is the warranty on units purchased from Konmask.com?
A: Standard 90-day warranty on all shipped units. Extended warranty available on request for volume orders.
Q: Do you provide datasheets or technical documentation?
A: Yes. Contact us with your part number and we will provide available documentation at no charge.
Q: Can you source other XYCOM XVME series modules?
A: Yes. Konmask.com specializes in legacy VME, PLC, and DCS components. Submit an RFQ for any XYCOM part number.
