Key Parameters

Substitute Part Grouping Explanation

Substitution of the M252532 is determined by strict equivalence across the following critical parameters:

• Off-state voltage rating of 600 V minimum
• Single-phase bridge configuration with four SCRs
• Chassis mount mechanical interface
• Gate trigger voltage and current specifications within acceptable operating ranges
• Surge current capability sufficient for application requirements
• RoHS3 compliance and REACH unaffected status for regulatory alignment

The VS-P132 manufactured by Vishay General Semiconductor meets these substitution criteria. Both parts share identical voltage ratings, bridge topology, mounting type, and regulatory compliance. Differences in gate trigger specifications and surge current ratings fall within acceptable tolerance bands for bridge rectifier applications.

Parameter Comparison

Engineering Selection Recommendations

The VS-P132 serves as a direct functional equivalent to the M252532 based on electrical specifications and regulatory compliance. Both components are RoHS3 compliant and REACH unaffected, meeting current environmental standards.

Key selection considerations:

• The VS-P132 is classified as active product status, ensuring continued availability and support compared to the M252532 not-for-new-designs status
• Surge current capability of the VS-P132 exceeds the M252532, providing enhanced transient protection
• Gate trigger specifications of the VS-P132 remain within acceptable operating margins for bridge rectifier control circuits
• Package configuration differs (8-PACE-PAK versus Module); mechanical mounting interface must be verified for the specific application

Selection should prioritize the VS-P132 for new installations and ongoing system support due to active product status and superior surge current rating.

Frequently Asked Questions (FAQ)

Q: Can the VS-P132 directly replace the M252532 in existing applications?

A: Electrical substitution is valid based on matching voltage ratings, bridge topology, and gate trigger specifications. Mechanical compatibility must be confirmed, as the VS-P132 uses 8-PACE-PAK packaging while the M252532 uses standard module packaging. Mounting interface verification is required before installation.

Q: What are the key differences between these two SCR bridge modules?

A: Both modules share 600V off-state voltage, single-phase bridge configuration, and four-SCR topology. The VS-P132 provides higher surge current capability (357-375A versus 300A), higher hold current specification (130mA versus 75mA), and defined operating temperature range (-40°C to 125°C). Package type differs between the two designs.

Q: Why is the M252532 marked as not for new designs?

A: This designation indicates the part is in mature or end-of-life status. The VS-P132, classified as active, represents the current generation equivalent and is recommended for new system designs and long-term support.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the M252532 and VS-P132 are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What should be verified before substituting the VS-P132 for the M252532?

A: Confirm mechanical mounting compatibility with the 8-PACE-PAK package format. Verify gate trigger circuit design accommodates the VS-P132 specifications (2V Vgt max, 60mA Igt max). Validate thermal management for the application, as the VS-P132 provides defined operating temperature range.
