P4KE200C Equivalent & Substitute Parts

Part Overview

The P4KE200C is a bidirectional transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. This component features a 171V reverse standoff voltage, 287.7V maximum clamping voltage, and 400W peak pulse power rating in a through-hole DO-204AL (DO-41) package. The part is currently classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement.

Engineering Selection Recommendations

All listed substitute parts are active products with ROHS3 compliance, providing long-term availability and regulatory alignment. The P4KE200CAHE3/54 variant includes AEC-Q101 automotive qualification, suitable for applications requiring automotive-grade reliability standards.

For applications with maximum operating temperature requirements at 175°C, select from P4KE200CA, BZW04-171B-E3/54, P4KE200CA-E3/54, P4KE200CAHE3/54, P4KE200CA-AP, P4KE200CA-BP, or P4KE200CA-TP. The P4KE200CA-G variant operates to 150°C maximum and is suitable only for applications with lower thermal requirements.

Packaging format selection depends on assembly methodology: Tape & Reel (TR) packaging suits automated pick-and-place assembly, while Bulk packaging accommodates manual or semi-automated processes. Electrical performance remains identical across packaging formats.

Frequently Asked Questions (FAQ)

Q: Can P4KE200CA directly replace P4KE200C in existing designs?

A: Yes. Both parts maintain 171V reverse standoff voltage, 400W peak pulse power, and identical operating temperature range (-55°C ~ 175°C). The clamping voltage difference (274V vs. 287.7V) falls within acceptable tolerance for general-purpose transient suppression applications. Through-hole DO-204AL (DO-41) package compatibility is confirmed.

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

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape suitable for automated assembly equipment. Bulk packaging supplies loose components for manual handling or semi-automated processes. Electrical specifications and performance are identical; packaging format affects only procurement and assembly workflow.

Q: Is P4KE200CA-G suitable for all applications?

A: P4KE200CA-G operates to a maximum junction temperature of 150°C, compared to 175°C for other substitutes. Applications requiring sustained operation above 150°C must use alternative parts. For general-purpose applications within the 150°C limit, P4KE200CA-G is electrically equivalent.

Q: Does the P4KE200CAHE3/54 automotive qualification affect non-automotive applications?

A: No. AEC-Q101 qualification indicates enhanced reliability testing and traceability suitable for automotive environments. Non-automotive applications benefit from this additional qualification without penalty. All electrical parameters remain identical to non-automotive variants.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, ensuring regulatory alignment with current environmental and hazardous substance restrictions.
