Key Parameters

Substitute Part Grouping Explanation

Substitution of the P1402AB60 is determined by electrical and mechanical parameter equivalence. The following criteria establish valid substitutes:

• Voltage ratings (breakover and off-state) must match exactly: 77V/154V breakover and 58V/116V off-state
• Peak pulse current capability must meet or exceed 250A (8/20µs) and 80A (10/1000µs)
• On-state voltage must remain at 4V
• Hold current (Ih) must be 150mA
• Dual-element configuration (2 elements) is required
• Capacitance values must be 90pF and 155pF
• Package must be 3-SIP with TO-220 Modified form factor
• Through-hole mounting compatibility is mandatory

The P1402ABL60 meets all these criteria and qualifies as a direct electrical and mechanical substitute.

Engineering Selection Recommendations

The P1402ABL60 is the qualified substitute for the obsolete P1402AB60. Selection between these parts should be based on the following factors:

Product Status: The P1402AB60 is obsolete with 845 units in stock. The P1402ABL60 is active with 721 units in stock, providing long-term availability for new designs and ongoing production support.

Compliance Considerations: The P1402ABL60 is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The P1402AB60 is RoHS non-compliant, which may restrict use in regulated applications and markets with environmental compliance mandates.

Electrical Equivalence: Both parts are electrically identical across all specified parameters, ensuring direct functional replacement without circuit redesign.

Packaging: Both components use identical 3-SIP TO-220 Modified packaging with through-hole mounting, allowing direct PCB substitution without layout modifications.

For new designs and production continuity, the P1402ABL60 is the appropriate selection due to active product status and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the P1402ABL60 replace the P1402AB60 in existing designs?

A: Yes. The P1402ABL60 is electrically and mechanically identical to the P1402AB60 across all specified parameters, including voltage ratings, current ratings, capacitance, and package form factor. Direct substitution is possible without circuit modifications.

Q: What is the primary reason to substitute the P1402AB60?
