P6KE7.5CA-B Equivalent & Substitute Parts

Part Overview

The P6KE7.5CA-B is a Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose voltage protection applications. This through-hole component operates with a 6.4V reverse standoff voltage and provides 11.3V maximum clamping voltage with 54A peak pulse current capability. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity while maintaining equivalent electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P6KE7.5CA-B are qualified based on the following critical electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 6.4V
• Voltage - Breakdown (Min): 7.13V
• Voltage - Clamping (Max) @ Ipp: 11.3V
• Current - Peak Pulse (10/1000µs): 53A–55A (within acceptable tolerance)
• Power - Peak Pulse: 600W
• Package / Case: DO-204AC, DO-15, Axial
• Mounting Type: Through Hole
• Operating Temperature: -55°C ~ 175°C (TJ)
• RoHS Status: ROHS3 Compliant
• Product Status: Active

All substitute parts maintain identical voltage specifications, equivalent peak pulse current ratings, and compatible through-hole axial packaging. Differences in packaging format (Bulk vs. Cut Tape) and manufacturer do not affect electrical performance or board-level compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts—P6KE7.5CA-B, P6KE7.5CA, and P6KE7.5CA-TP—are active products with full RoHS3 compliance and REACH unaffected status. Peak pulse current ratings vary minimally (53A–55A), remaining within acceptable tolerance for general-purpose TVS applications. All parts share identical voltage specifications, thermal operating range, and through-hole axial packaging, ensuring direct board-level substitution without design modification.

Selection between these parts should be based on packaging availability (Bulk vs. Cut Tape), supplier inventory, and procurement lead times rather than electrical performance differences.

Frequently Asked Questions (FAQ)

Q: Can P6KE7.5CA-B be directly replaced with P6KE7.5CA or P6KE7.5CA-TP?

A: Yes. All three parts maintain identical voltage specifications (6.4V reverse standoff, 7.13V breakdown minimum, 11.3V clamping maximum), equivalent peak pulse current ratings (53A–55A), and compatible DO-15 axial through-hole packaging. Direct substitution is supported without circuit redesign.

Q: What is the difference between Bulk and Cut Tape packaging?

A: Bulk packaging (P6KE7.5CA-B) supplies components in loose form, while Cut Tape (P6KE7.5CA-TP) provides components on continuous tape for automated assembly. Electrical performance and board-level compatibility are identical; packaging format affects only handling and assembly methodology.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. P6KE7.5CA-B, P6KE7.5CA, and P6KE7.5CA-TP are all ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: Do peak pulse current differences (53A vs. 54A vs. 55A) affect circuit performance?

A: No. These variations fall within normal manufacturing tolerance for TVS diodes and do not impact circuit protection performance in general-purpose applications where all parts meet the 600W peak pulse power specification.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. Identical voltage ratings, thermal operating range (-55°C to 175°C), and through-hole axial package configuration ensure full interchangeability without PCB layout or schematic modifications.
