5KP58A-B Equivalent & Substitute Parts

Part Overview

The 5KP58A-B is a unidirectional transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose transient voltage protection applications. This through-hole component features a 58V reverse standoff voltage with a 93.6V maximum clamping voltage and 54.5A peak pulse current capability. The part is currently in active production status and is RoHS3 compliant. Substitute parts are identified when packaging or inventory requirements necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The 5KP58A-B can be substituted with the 5KP58A based on strict electrical and mechanical parameter equivalence. Both parts share identical specifications across all critical performance parameters: 58V reverse standoff voltage, 64.4V minimum breakdown voltage, 93.6V maximum clamping voltage, 54.5A peak pulse current, and 5000W peak pulse power rating. Both components utilize the P600 axial through-hole package and operate across the same temperature range (-55°C to 175°C). The substitution is valid based on matching:

• Voltage ratings (standoff, breakdown, and clamping)
• Current and power specifications
• Package type and form factor
• Temperature operating range
• Compliance certifications (RoHS3, REACH Unaffected)

The primary difference between these parts is packaging format: the 5KP58A-B is supplied in bulk packaging, while the 5KP58A is supplied in cut tape (CT) packaging. This distinction affects inventory management and automated assembly processes but does not alter electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

Both the 5KP58A-B and 5KP58A are active production components from Littelfuse Inc. with identical electrical performance and mechanical specifications. Selection between these parts should be based on packaging and supply chain requirements:

• 5KP58A-B (Bulk Packaging): Suitable for applications requiring loose component handling or custom packaging integration. Current inventory: 909 pcs.
• 5KP58A (Cut Tape Packaging): Suitable for automated assembly processes and standard component tape-and-reel handling. Current inventory: 4400 pcs.

Both parts maintain full RoHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The selection of either part does not compromise circuit performance, reliability, or compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the 5KP58A replace the 5KP58A-B in my circuit?

A: Yes. Both parts are electrically and mechanically identical. The 5KP58A operates at the same voltage ratings (58V standoff, 93.6V clamping), current specifications (54.5A peak pulse), and power dissipation (5000W). Both use the P600 axial through-hole package and operate across -55°C to 175°C. The only difference is packaging format (cut tape versus bulk).

Q: What is the difference between bulk and cut tape packaging?

A: Bulk packaging supplies loose components suitable for manual assembly or custom packaging. Cut tape packaging supplies components on standard carrier tape, optimized for automated pick-and-place assembly equipment. Electrically and mechanically, the components are identical.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the 5KP58A-B and 5KP58A are RoHS3 compliant and REACH unaffected, meeting regulatory requirements for use in regulated markets.

Q: Can I use these parts interchangeably in high-temperature applications?

A: Yes. Both parts operate across the same temperature range (-55°C to 175°C junction temperature) and maintain identical electrical specifications across this range.

Q: Which part should I select for automated assembly?

A: The 5KP58A in cut tape packaging is designed for automated pick-and-place assembly. The 5KP58A-B in bulk packaging is suitable for manual assembly or custom packaging workflows.
