5KP58CA-B Equivalent & Substitute Parts

Part Overview

The 5KP58CA-B is a bidirectional transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. This through-hole component operates with a reverse standoff voltage of 58V and provides peak pulse power dissipation of 5000W. The part is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when packaging configurations differ or when equivalent electrical performance is required from alternative inventory sources while maintaining identical electrical specifications and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5KP58CA-B is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 58V
• Voltage - Breakdown (Min): 64.4V
• Voltage - Clamping (Max) @ Ipp: 93.6V
• Current - Peak Pulse (10/1000µs): 54.5A
• Power - Peak Pulse: 5000W
• Mounting Type: Through Hole
• Package / Case: P600, Axial
• Bidirectional Channels: 1
• Operating Temperature Range: -55°C to 175°C (TJ)

The identified substitute part 5KP58CA maintains identical electrical performance and mechanical specifications. The primary distinction is packaging configuration: the main part (5KP58CA-B) is supplied in bulk packaging, while the substitute (5KP58CA) is supplied in cut tape (CT) packaging. Both parts are manufactured by Littelfuse Inc., share the same base product number (5KP5), and carry equivalent compliance certifications (RoHS3, REACH Unaffected, MSL 1).

Parameter Comparison

Engineering Selection Recommendations

Selection between 5KP58CA-B and 5KP58CA is based on packaging and supply chain requirements rather than electrical or mechanical performance differences. Both parts are active products from Littelfuse Inc. with identical electrical specifications, thermal ratings, and compliance certifications.

The 5KP58CA-B in bulk packaging is suitable for high-volume manufacturing environments where components are supplied in loose form for automated or manual assembly processes. The 5KP58CA in cut tape (CT) packaging is appropriate for automated pick-and-place assembly systems and tape-reel handling equipment.

Both parts maintain RoHS3 compliance, REACH unaffected status, and unlimited moisture sensitivity rating (MSL 1), ensuring compatibility with modern manufacturing and environmental standards. Selection should be based on assembly equipment capability and inventory management protocols rather than technical performance criteria.

Frequently Asked Questions (FAQ)

Q: Can 5KP58CA (cut tape) be used as a direct replacement for 5KP58CA-B (bulk)?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format only. Cut tape packaging is compatible with automated assembly equipment, while bulk packaging requires manual or alternative handling methods.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts share identical specifications for reverse standoff voltage (58V), breakdown voltage (64.4V minimum), clamping voltage (93.6V maximum), peak pulse current (54.5A), and peak pulse power (5000W).

Q: Do both parts meet the same compliance standards?

A: Yes. Both 5KP58CA-B and 5KP58CA are RoHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -55°C to 175°C junction temperature (TJ).

Q: Are these parts suitable for the same circuit applications?

A: Yes. Both parts are designed for general-purpose transient voltage suppression in through-hole P600 axial package configurations. Electrical performance and thermal characteristics are identical.

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

A: Bulk packaging supplies components loose in a container for manual assembly or non-automated processes. Cut tape (CT) packaging supplies components on continuous tape in reels, optimized for automated pick-and-place assembly systems.
