P1402ACRP Equivalent & Substitute Parts

Part Overview

The P1402ACRP is a SIDACtor® thyristor transient voltage suppressor manufactured by Littelfuse Inc., designed for overvoltage protection applications requiring 58V/116V off-state voltage ratings with 400A peak pulse current capability. This component is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing system support and new design implementations. The part is packaged in a 3-SIP TO-220 Modified configuration suitable for through-hole mounting applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P1402ACRP is determined by strict equivalence across the following electrical and mechanical parameters:

• Voltage ratings: Breakover voltage (77V, 154V) and off-state voltage (58V, 116V) must match exactly
• Current specifications: Peak pulse current (8/20µs) of 400A and (10/1000µs) of 100A must be maintained
• On-state voltage: 4V characteristic
• Hold current: 150mA minimum
• Capacitance values: 90pF and 155pF
• Physical form factor: 3-SIP package in TO-220 Modified configuration with through-hole mounting

The P1402ACLRP meets all these criteria and is therefore a direct functional equivalent. The primary distinction between these parts is packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The P1402ACLRP is the direct substitute for the obsolete P1402ACRP. Both components are manufactured by Littelfuse and share identical electrical characteristics and physical form factors. The P1402ACLRP maintains active product status, ensuring continued availability and supply chain reliability.

The P1402ACLRP carries ROHS3 compliance certification, whereas the P1402ACRP is non-compliant. For applications subject to RoHS regulatory requirements, the P1402ACLRP is the appropriate selection. The P1402ACLRP is supplied in Tape & Reel format, which is standard for production environments, while the P1402ACRP was supplied in bulk packaging.

Both parts are suitable for direct pin-for-pin replacement in existing circuit designs without modification to PCB layouts or electrical schematics.

Frequently Asked Questions (FAQ)

Q: Can the P1402ACLRP be used as a direct replacement for the P1402ACRP?

A: Yes. The P1402ACLRP is electrically and mechanically identical to the P1402ACRP across all specified parameters, including voltage ratings, current ratings, capacitance values, and physical package configuration. Direct substitution is possible without circuit redesign.

Q: What is the primary difference between these two parts?

A: The P1402ACRP is obsolete, while the P1402ACLRP is active. Additionally, the P1402ACLRP is ROHS3 compliant and supplied in Tape & Reel packaging, whereas the P1402ACRP is non-compliant and supplied in bulk format.

Q: Are there any compatibility concerns when switching from P1402ACRP to P1402ACLRP?

A: No compatibility concerns exist. Both parts share identical electrical specifications and the same 3-SIP TO-220 Modified package configuration. PCB footprints and circuit designs require no modification.

Q: Which part should be selected for new designs?

A: The P1402ACLRP should be selected for new designs. It is the active product with current manufacturing support and regulatory compliance certifications.

Q: Does the Tape & Reel packaging of the P1402ACLRP affect circuit performance?

A: No. Packaging format does not affect electrical performance or functional characteristics. Tape & Reel packaging is a supply format used for automated assembly processes and does not impact the component's operation in the circuit.
