5KP64CA-B Equivalent & Substitute Parts

Part Overview

The 5KP64CA-B is a bidirectional Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose transient protection applications. This through-hole component operates with a 64V reverse standoff voltage and provides 5000W peak pulse power dissipation. The part is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when packaging or inventory requirements necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the 5KP64CA-B is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must remain identical for a part to qualify as a direct substitute:

• Voltage - Reverse Standoff (Typ): 64V
• Voltage - Breakdown (Min): 71.1V
• Voltage - Clamping (Max) @ Ipp: 103V
• Current - Peak Pulse (10/1000µs): 49.5A
• Power - Peak Pulse: 5000W
• Mounting Type: Through Hole
• Package / Case: P600, Axial
• Bidirectional Channels: 1
• Operating Temperature Range: -55°C to 175°C

The 5KP64CA-B differs from its substitute only in packaging format (Bulk vs. Cut Tape), which does not affect electrical performance or mechanical compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 5KP64CA-B and 5KP64CA are active production components from Littelfuse Inc. with identical electrical specifications and mechanical form factors. Selection between these parts is determined by procurement and assembly requirements rather than technical performance criteria.

The 5KP64CA-B in Bulk packaging is suitable for high-volume manufacturing environments with automated handling systems. The 5KP64CA in Cut Tape (CT) packaging is appropriate for lower-volume production, kit assembly, or applications requiring individual component dispensing.

Both parts maintain full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1), ensuring compatibility with standard manufacturing processes and long-term storage without special handling requirements.

Frequently Asked Questions (FAQ)

Q: Can 5KP64CA (Cut Tape) be used as a direct replacement for 5KP64CA-B (Bulk)?

A: Yes. The electrical and mechanical specifications are identical. The only difference is packaging format. Both parts are suitable for the same circuit applications without modification.

Q: Does packaging format affect circuit performance?

A: No. Packaging format (Bulk vs. Cut Tape) affects only handling, storage, and assembly processes. Once soldered into a circuit, both parts perform identically.

Q: Are there any compliance differences between these parts?

A: No. Both parts carry identical RoHS3 compliance status and moisture sensitivity ratings (MSL 1 - Unlimited). They meet the same regulatory and environmental standards.

Q: Which part should be selected for new designs?

A: Either part is acceptable for new designs. Selection depends on manufacturing volume and assembly equipment compatibility. Consult your procurement and manufacturing teams regarding packaging preferences.

Q: Can these parts be intermixed in production?

A: Yes, provided your assembly equipment can handle both packaging formats. Verify compatibility with your pick-and-place systems and tape feeder specifications before implementation.
