5KP10A-B Transient Voltage Suppressor Equivalent & Substitute Parts

Part Overview

The 5KP10A-B is a unidirectional Zener transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. This through-hole component features a 10V reverse standoff voltage with 17V maximum clamping voltage and 300A peak pulse current capability. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified based on matching electrical characteristics and mechanical compatibility within the P600/R-6 axial package family.

Substitute Part Grouping Explanation

Substitution eligibility for the 5KP10A-B is determined by the following critical parameters:

  • Voltage - Reverse Standoff: 10V (exact match required)
  • Voltage - Clamping (Max) @ Ipp: 17V (exact match required)
  • Current - Peak Pulse (10/1000µs): 300A (exact match required)
  • Power - Peak Pulse: 5000W (exact match required)
  • Operating Temperature Range: -55°C to 175°C (exact match required)
  • Mounting Type: Through Hole (exact match required)
  • Package / Case: P600 or R-6 Axial (compatible variants)
  • Type: Zener, Unidirectional (exact match required)

The identified substitute parts maintain identical electrical performance specifications while differing in packaging format (Cut Tape vs. Bulk) and manufacturer source. Both substitute parts meet ROHS3 compliance and MSL 1 requirements.

Engineering Selection Recommendations

All three parts maintain active product status with ROHS3 compliance and identical moisture sensitivity ratings. Selection between 5KP10A-B, 5KP10A, and 5KP10A-TP is determined by packaging requirements and supply chain considerations:

  • 5KP10A-B (Littelfuse, Bulk): Original specification part with 693 units in stock. Suitable for applications requiring bulk component procurement.

  • 5KP10A (Littelfuse, Cut Tape): Manufacturer-recommended substitute with identical electrical specifications and P600 package. Higher inventory availability (4270 units) supports continuous production requirements.

  • 5KP10A-TP (Micro Commercial Co, Cut Tape): Alternative source substitute with R-6 axial package variant. Maintains electrical performance specifications with 1181 units available. Peak pulse current specification not provided in documentation.

All parts satisfy ECCN EAR99 and HTSUS 8541.10.0080 classifications with REACH unaffected status.

Frequently Asked Questions (FAQ)

Q: Can 5KP10A-B be directly replaced with 5KP10A?

A: Yes. Both parts are manufactured by Littelfuse with identical electrical specifications (10V standoff, 17V clamping, 300A peak pulse, 5000W power rating) and P600 axial package. The difference is packaging format: 5KP10A-B is supplied in bulk, while 5KP10A is supplied in cut tape. Electrical performance and mechanical fit are equivalent.

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

A: Both are axial through-hole packages for the 5KP series. P600 is the standard Littelfuse package designation, while R-6 is the Micro Commercial Co equivalent package designation. Both accommodate the same lead diameter and spacing for through-hole PCB mounting.

Q: Is 5KP10A-TP a suitable substitute if peak pulse current is not specified?

A: The 5KP10A-TP maintains all other critical electrical parameters (10V standoff, 17V clamping, 5000W power rating, -55°C to 175°C operating range) and is listed as an active substitute. However, the absence of peak pulse current specification in available documentation should be verified against application requirements before selection.

Q: Are all three parts ROHS3 compliant?

A: Yes. All three parts (5KP10A-B, 5KP10A, and 5KP10A-TP) carry ROHS3 compliance certification with MSL 1 (unlimited) moisture sensitivity rating.

Q: Which substitute part has the highest inventory availability?

A: The 5KP10A (Littelfuse, Cut Tape) has 4270 units in stock, compared to 693 units for 5KP10A-B and 1181 units for 5KP10A-TP.
