B612-2 SCR Module Equivalent & Substitute Parts

Part Overview

The B612-2 is a thyristor module manufactured by Sensata-Crydom, classified as a bridge-configured SCR/diode assembly for single-phase applications. This module integrates two SCRs and two diodes in a chassis mount configuration with 600V off-state voltage rating and 42.5A current capacity at 240V operation. The B612-2 is currently listed as obsolete, making identification of active equivalent parts essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the B612-2 is determined by strict equivalence across the following electrical and mechanical parameters:

• Bridge configuration with single-phase SCRs/Diodes (Layout 1)
• Identical component count: 2 SCRs and 2 Diodes
• Off-state voltage: 600 V
• Gate trigger voltage (Vgt) maximum: 3 V
• Gate trigger current (Igt) maximum: 80 mA
• Non-repetitive surge current: 600A @ 60Hz
• Operating temperature range: -40°C ~ 125°C
• Chassis mount configuration
• Module package type

The B612F-2T meets all these criteria and serves as the manufacturer-recommended substitute for the obsolete B612-2.

Parameter Comparison

Engineering Selection Recommendations

The B612F-2T is the direct active equivalent for the obsolete B612-2. Both parts share identical electrical specifications and mechanical configuration. The B612F-2T is currently in active production status with substantial inventory availability (20,099 pcs), ensuring reliable procurement for replacement and new applications.

The B612F-2T carries ROHS3 compliance, meeting current environmental regulatory requirements. The transition from REACH Unaffected (B612-2) to REACH Affected (B612F-2T) reflects updated regulatory classification and does not impact functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the B612F-2T directly replace the B612-2 in existing applications?

A: Yes. The B612F-2T is electrically and mechanically equivalent to the B612-2 across all specified parameters, including voltage ratings, current ratings, gate trigger characteristics, temperature range, and chassis mount configuration.

Q: What is the difference between the B612-2 and B612F-2T?
