P4KE250C Equivalent & Substitute Parts

Part Overview

The P4KE250C is a bidirectional transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. This component features a 214V reverse standoff voltage rating and 400W peak pulse power handling capability in a through-hole DO-204AL (DO-41) package. The part is currently listed as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P4KE250C is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 214V
• Voltage - Breakdown (Min): 225V minimum
• Current - Peak Pulse (10/1000µs): 1.2A
• Power - Peak Pulse: 400W
• Mounting Type: Through Hole
• Package / Case: DO-204AL or DO-41
• Operating Temperature Range: -55°C to 175°C minimum

All substitute parts listed maintain these core electrical and mechanical specifications, ensuring functional equivalence in general-purpose transient voltage suppression applications. Substitute parts are grouped by manufacturer and product status (active vs. obsolete).

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status, ensuring long-term availability and manufacturing support. The following considerations apply:

Primary Substitutes (Highest Compatibility):

• P4KE250CA (Taiwan Semiconductor Corporation) and P4KE250CA-E3/54 (Vishay General Semiconductor) are direct functional equivalents with identical electrical specifications and full DO-204AL package support. Both are ROHS3 compliant and rated to 175°C.

Secondary Substitutes (Minor Deviations):

• P4KE250CA-AP, P4KE250CA-BP, and P4KE250CA-TP (Micro Commercial Co) provide equivalent electrical performance with DO-41 package configuration. Operating temperature range is maintained at -55°C to 175°C.
• P4KE250CA-G (Comchip Technology) is functionally equivalent with a slightly reduced peak pulse current specification (1.16A vs. 1.2A) and maximum operating temperature of 150°C instead of 175°C. ROHS3 compliance is confirmed.

All substitute parts are rated for general-purpose transient voltage suppression and maintain the same base product number (P4KE250), confirming electrical equivalence within the P4KE series.

Frequently Asked Questions (FAQ)

Q: Can P4KE250CA-G be used as a direct replacement for P4KE250C in all applications? A: P4KE250CA-G is electrically equivalent for general-purpose applications but has a reduced maximum operating temperature of 150°C compared to the 175°C rating of the original part. Applications requiring operation above 150°C require alternative substitutes.

Q: What is the difference between DO-204AL and DO-41 package designations? A: DO-204AL and DO-41 are equivalent axial through-hole package designations for this component category. Both support identical lead spacing and mounting on standard PCB layouts.

Q: Are all substitute parts ROHS3 compliant? A: P4KE250CA (Taiwan Semiconductor), P4KE250CA-E3/54 (Vishay), and P4KE250CA-G (Comchip) are confirmed ROHS3 compliant. Compliance status for Micro Commercial Co variants (P4KE250CA-AP, P4KE250CA-BP, P4KE250CA-TP) is not specified in available documentation.

Q: Which substitute offers the best long-term availability? A: All listed substitutes maintain active product status. P4KE250CA (Taiwan Semiconductor) and P4KE250CA-E3/54 (Vishay) are established manufacturers with extensive distribution networks.

Q: Can packaging format (Tape & Reel vs. Bulk) affect electrical performance? A: Packaging format does not affect electrical performance. Tape & Reel packaging is suitable for automated assembly, while Bulk packaging is appropriate for manual assembly or lower-volume applications.
