P4KE62C-B Equivalent & Substitute Parts

Part Overview

The P4KE62C-B is a transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. This component features a 53V reverse standoff voltage with an 89.25V maximum clamping voltage and 4.8A peak pulse current capability in a through-hole DO-204AL (DO-41) package. The part is currently classified as obsolete, making identification of active equivalent alternatives essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P4KE62C-B is determined by the following critical parameters:

• Reverse standoff voltage: 53V (must match)
• Package type: DO-204AL (DO-41) through-hole axial (must match)
• Bidirectional channels: 1 (must match)
• Operating temperature range: -55°C to 175°C (must match)
• Peak pulse power: 400W (must match)
• RoHS3 compliance (required for modern procurement)

The identified substitute parts maintain these core electrical and mechanical specifications while offering active product status and improved availability compared to the obsolete P4KE62C-B.

Parameter Comparison

Engineering Selection Recommendations

Both P4KE62CA and P4KE62CA-B are active alternatives to the obsolete P4KE62C-B. Selection between these substitutes depends on procurement and packaging requirements:

P4KE62CA (Taiwan Semiconductor Corporation) is supplied in Tape & Reel format with 5A peak pulse current capability and active product status, supporting high-volume automated assembly operations.

P4KE62CA-B (Littelfuse Inc.) is supplied in bulk packaging with 4.8A peak pulse current, matching the original part's current specification, and maintains continuity with the original manufacturer while offering active product status.

Both alternatives meet ROHS3 compliance requirements and maintain identical reverse standoff voltage, operating temperature range, and package geometry specifications. The clamping voltage differential (85V versus 89.25V) and peak pulse current variations fall within the P4KE series design envelope and do not preclude functional substitution in general-purpose transient voltage suppression applications.

Frequently Asked Questions (FAQ)

Q: Can P4KE62CA or P4KE62CA-B be used as direct replacements for P4KE62C-B?

A: Both parts maintain the critical electrical parameters (53V reverse standoff, 400W peak pulse power) and identical package geometry (DO-204AL through-hole). The clamping voltage and peak pulse current variations are within the P4KE series specifications and do not prevent functional substitution in general-purpose applications.

Q: What is the difference between P4KE62CA and P4KE62CA-B?

A: The primary differences are manufacturer (Taiwan Semiconductor Corporation versus Littelfuse Inc.), packaging format (Tape & Reel versus bulk), and peak pulse current (5A versus 4.8A). Both maintain identical reverse standoff voltage and operating temperature specifications.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel and bulk packaging formats contain identical components and do not affect electrical characteristics. Packaging selection is determined by assembly process requirements and procurement volume.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. P4KE62CA and P4KE62CA-B are both ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: Why is the original P4KE62C-B classified as obsolete?

A: Product obsolescence is determined by manufacturer lifecycle decisions. Active alternatives with equivalent electrical specifications and package compatibility are available for design continuity.
