Equivalent & Substitute Parts for 3KP130CA-B

Part Overview

The 3KP130CA-B is a Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse, designed for general-purpose transient voltage protection in through-hole applications. This component features a 130V reverse standoff voltage with a 209V maximum clamping voltage and 14.4A peak pulse current capability. The part is currently classified as obsolete, making identification of suitable substitute components essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3KP130CA-B is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 130V
• Voltage - Clamping (Max) @ Ipp: 209V
• Operating Temperature Range: -55°C to 175°C
• Mounting Type: Through Hole
• Type: Zener, Bidirectional (1 channel)

Substitute parts must maintain identical voltage specifications and operating temperature range to ensure functional equivalence. Package variations (P600 vs. R-6) are permissible provided the through-hole mounting requirement is satisfied. Peak pulse current and power ratings may vary, provided the substitute meets or exceeds the original specification.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain electrical equivalence with the original 3KP130CA-B across critical voltage and temperature parameters. Selection should be based on the following factors:

5KP130CA-B (Littelfuse Inc.): Active product status with ROHS3 compliance and MSL 1 rating. Offers increased peak pulse current (24.4A) and power dissipation (5000W) compared to the original specification. Maintains P600 package compatibility. Recommended for designs requiring enhanced transient protection margin.

3KP130CA-TP (Micro Commercial Co): Active product status with electrical specifications matching the original 3KP130CA-B. Uses R-6 package instead of P600. Suitable for applications where package footprint variation is acceptable and original performance envelope is required.

5KP130CAE3/TR13 (Microchip Technology): Active product status with ROHS3 compliance and MSL 1 rating. Supplied in Tape & Reel packaging. Provides increased peak pulse current (24.4A) and power dissipation (5000W). Maintains P600 package compatibility. Appropriate for high-volume production environments.

Frequently Asked Questions (FAQ)

Q: Can 5KP130CA-B be used as a direct replacement for 3KP130CA-B?

A: Yes. Both parts maintain identical voltage specifications (130V reverse standoff, 209V clamping). The 5KP series provides higher peak pulse current (24.4A vs. 14.4A) and power dissipation (5000W vs. 3000W), making it functionally equivalent with enhanced capability margins. Package and mounting type are identical.

Q: What is the difference between P600 and R-6 packages?

A: Both are axial through-hole packages for TVS diodes. P600 and R-6 represent different package designations. The 3KP130CA-TP uses R-6 packaging while the original uses P600. Verify PCB footprint compatibility before substitution.

Q: Why is the original 3KP130CA-B classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Littelfuse. Active substitute options are available with equivalent or superior electrical performance.

Q: Are all substitutes RoHS3 compliant?

A: 5KP130CA-B, 3KP130CA-TP, and 5KP130CAE3/TR13 are specified as ROHS3 compliant. Verify compliance documentation for your specific application requirements.

Q: Can I use the higher-power 5KP series parts in place of the 3KP series?

A: Yes. The 5KP130CA-B and 5KP130CAE3/TR13 maintain all critical voltage and temperature specifications while providing increased current and power handling. This substitution is valid for applications where the original 3KP130CA-B was specified.
