P4KE200C-B Equivalent & Substitute Parts

Part Overview

The P4KE200C-B is a transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. This component features a 171V reverse standoff voltage with 287.7V maximum clamping voltage and 1.5A peak pulse current capability in a through-hole DO-204AL (DO-41) package. The part is currently listed as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P4KE200C-B are identified based on strict electrical and mechanical parameter compatibility within the P4KE series. The substitution criteria are:

• Identical reverse standoff voltage: 171V (Typ)
• Identical package type: DO-204AL (DO-41), through-hole axial configuration
• Identical bidirectional channel count: 1
• Identical operating temperature range: -55°C to 175°C (TJ)
• Identical power rating: 400W peak pulse
• Identical base product number: P4KE200
• Voltage breakdown minimum within acceptable range: 180V to 190V
• Peak pulse current within acceptable range: 1.5A to 1.51A
• Voltage clamping maximum within acceptable range: 274V to 287.7V

The following parts meet these criteria and are qualified as direct substitutes:

• P4KE200CA (Taiwan Semiconductor Corporation)
• P4KE200CA-B (Littelfuse Inc.)

Parameter Comparison

Engineering Selection Recommendations

Both P4KE200CA and P4KE200CA-B are qualified substitutes for the obsolete P4KE200C-B based on electrical parameter compatibility and regulatory compliance.

P4KE200CA-B is the preferred substitute when available, as it is manufactured by Littelfuse Inc., the original manufacturer of the P4KE200C-B, ensuring design continuity and manufacturing consistency. This part maintains identical peak pulse current specification (1.5A) and is currently in active production status with bulk packaging availability.

P4KE200CA, manufactured by Taiwan Semiconductor Corporation, is an alternative substitute with active product status. This part exhibits marginally improved voltage breakdown specification (190V minimum versus 180V) and slightly enhanced peak pulse current (1.51A versus 1.5A), while maintaining identical clamping voltage performance within the acceptable range. This part is available in tape and reel packaging.

Both substitutes maintain full compliance with RoHS3 regulations, identical moisture sensitivity levels, and matching export control classifications. Selection between these two substitutes should be based on packaging requirements, supply chain availability, and procurement lead times.

Frequently Asked Questions (FAQ)

Q: Can P4KE200CA or P4KE200CA-B be used as direct replacements for P4KE200C-B in existing designs?

A: Yes. Both parts are electrically and mechanically compatible. They share identical reverse standoff voltage (171V), operating temperature range (-55°C to 175°C), power rating (400W), and package configuration (DO-204AL through-hole). Voltage clamping and breakdown specifications fall within acceptable operating ranges for this product category.

Q: What is the difference between P4KE200CA and P4KE200CA-B?

A: The primary differences are manufacturer and packaging. P4KE200CA is manufactured by Taiwan Semiconductor Corporation and supplied in tape and reel format. P4KE200CA-B is manufactured by Littelfuse Inc. and supplied in bulk packaging. Electrically, P4KE200CA exhibits slightly higher breakdown voltage (190V minimum) and peak pulse current (1.51A) specifications compared to P4KE200CA-B (190V minimum, 1.5A), though both remain within acceptable operating parameters.

Q: Are there any compliance or certification differences between these parts?

A: No. All three parts (P4KE200C-B, P4KE200CA, and P4KE200CA-B) maintain identical RoHS3 compliance status, moisture sensitivity level (MSL 1 - Unlimited), ECCN classification (EAR99), and HTSUS code (8541.10.0080).

Q: Which substitute should be selected for new designs?

A: For new designs, either P4KE200CA or P4KE200CA-B is acceptable. P4KE200CA-B is recommended when Littelfuse Inc. sourcing is preferred for supply chain consistency. P4KE200CA is recommended when tape and reel packaging is required for automated assembly processes.

Q: Is the voltage clamping difference (287.7V versus 274V) significant for substitution?

A: No. The voltage clamping specification represents the maximum voltage at peak pulse current. The substitute parts' 274V clamping voltage is lower than the original 287.7V, which provides improved protection performance. Both values remain within acceptable operating ranges for general-purpose transient voltage suppression applications.

Q: Can these parts be used interchangeably in the same circuit board layout?

A: Yes. All three parts use identical DO-204AL (DO-41) through-hole axial package configuration with matching pin spacing and mechanical dimensions, allowing direct board-level substitution without layout modifications.
