Key Parameters

Substitute Part Grouping Explanation

Substitution of the M252535V is determined by the following critical parameters that must remain equivalent or superior:

• Voltage Rating (Off State): Must be 1.2 kV minimum to maintain blocking capability
• Current Capacity: Must support 25A continuous operation
• Bridge Configuration: Must maintain single-phase bridge topology with four SCRs
• Mounting Type: Chassis mount configuration required for mechanical compatibility
• Gate Trigger Parameters: Vgt and Igt specifications define control circuit compatibility
• Surge Current Rating (Itsm): Must meet or exceed 300A @ 60Hz for transient protection
• Hold Current (Ih): Must support specified hold current requirements
• RoHS Compliance: Environmental regulatory compliance for procurement

The VS-P135 from Vishay General Semiconductor meets these substitution criteria while offering active product status and enhanced specifications in several parameters.

Parameter Comparison

Engineering Selection Recommendations

The VS-P135 serves as a direct functional substitute for the obsolete M252535V based on the following engineering criteria:

Electrical Equivalence: Both devices maintain identical voltage ratings (1.2 kV), current capacity (25A), and bridge topology. The VS-P135 demonstrates superior surge current handling (357A/375A versus 300A), providing enhanced transient protection in the same application envelope.

Regulatory Compliance: Both parts maintain RoHS compliance status. The VS-P135 carries ROHS3 certification and REACH unaffected status, meeting current environmental procurement standards.

Product Availability: The M252535V is obsolete with limited remaining inventory (851 pcs). The VS-P135 is actively manufactured with substantial stock availability (3288 pcs), ensuring long-term supply chain continuity.

Package Consideration: The VS-P135 uses 8-PACE-PAK packaging versus the generic Module designation of the M252535V. Physical mounting verification is required to confirm mechanical compatibility in existing chassis mount applications.

Gate Control Parameters: The VS-P135 exhibits lower gate trigger voltage (2V versus 2.5V), potentially requiring control circuit verification to ensure gate drive compatibility with existing trigger circuits designed for the M252535V specifications.

Frequently Asked Questions (FAQ)

Q: Can VS-P135 directly replace M252535V in existing applications?

A: Electrical substitution is valid based on voltage rating, current capacity, and bridge configuration equivalence. Physical package compatibility must be verified, as the VS-P135 uses 8-PACE-PAK form factor. Gate drive circuits should be evaluated for the lower trigger voltage specification (2V versus 2.5V).

Q: What are the key differences between these parts?

A: Primary differences include package form factor (8-PACE-PAK versus Module), gate trigger voltage (2V versus 2.5V), surge current rating (357A/375A versus 300A), and product status (Active versus Obsolete). Electrical ratings for voltage and current capacity remain equivalent.

Q: Is the higher surge current rating of VS-P135 beneficial?

A: The VS-P135 surge current rating of 357A/375A exceeds the M252535V specification of 300A @ 60Hz, providing enhanced transient protection. This represents a performance improvement for applications subject to inrush currents or fault conditions.

Q: What compliance certifications apply to these parts?

A: Both parts maintain RoHS compliance. The M252535V is RoHS Compliant. The VS-P135 carries ROHS3 Compliant certification and is REACH Unaffected, meeting current environmental regulatory requirements.

Q: Are there inventory considerations for this substitution?

A: The M252535V is obsolete with 851 pcs remaining in stock. The VS-P135 is actively manufactured with 3288 pcs available, providing superior long-term supply chain security for ongoing production and maintenance applications.

Q: How do gate trigger parameters affect circuit design?

A: The VS-P135 gate trigger voltage is 2V maximum versus 2.5V for the M252535V. Existing gate drive circuits designed for the M252535V should be evaluated to confirm adequate drive margin with the lower trigger threshold of the substitute part.
