Engineering Selection Recommendations

The 5KP250CA is the direct equivalent substitute for the obsolete 5KP250C. Selection of the 5KP250CA is based on the following engineering criteria:

Product Status: The 5KP250C is classified as Obsolete, limiting long-term procurement viability. The 5KP250CA maintains Active status, ensuring continued availability and manufacturer support.

Electrical Equivalence: All critical electrical parameters are identical between the two parts, including reverse standoff voltage, breakdown voltage, clamping voltage, peak pulse current, and peak pulse power. This ensures functional interchangeability without circuit redesign.

Compliance: Both parts are RoHS Compliant. The 5KP250CA carries ROHS3 Compliant certification, representing the current regulatory standard. Both parts are classified as EAR99 for export control purposes and share identical HTSUS tariff classification.

Physical Form Factor: Both parts utilize identical P600 axial through-hole packaging, enabling direct mechanical substitution on existing printed circuit boards without layout modification.

Environmental Performance: Operating temperature ranges are identical across both parts, maintaining thermal performance specifications for the intended application environment.

Frequently Asked Questions (FAQ)

Q: Can the 5KP250CA be used as a direct replacement for the 5KP250C in existing designs?

A: Yes. The 5KP250CA is electrically and mechanically equivalent to the 5KP250C. All critical parameters—including voltage ratings, current ratings, power dissipation, operating temperature range, and physical package dimensions—are identical. Direct substitution is possible without circuit modification.

Q: What is the primary reason for substituting the 5KP250C?

A: The 5KP250C is classified as Obsolete, which restricts procurement availability and manufacturer support. The 5KP250CA is an Active product from the same manufacturer and series, providing equivalent performance with assured long-term availability.

Q: Are there packaging differences between the 5KP250C and 5KP250CA?

A: Both parts use the P600 axial through-hole package. The 5KP250C is supplied in standard packaging, while the 5KP250CA is available in Cut Tape (CT) packaging. Both are physically identical and mount identically on printed circuit boards.

Q: Do the RoHS compliance levels differ between these parts?

A: The 5KP250C is RoHS Compliant, while the 5KP250CA is ROHS3 Compliant. ROHS3 represents the current regulatory standard and is fully backward compatible with RoHS requirements. This difference does not affect substitution suitability.

Q: Are the electrical performance characteristics identical?

A: Yes. Both parts share identical specifications for reverse standoff voltage (250V), breakdown voltage (277V minimum), clamping voltage (425V maximum), peak pulse current (12A), and peak pulse power (5000W). Operating temperature range is also identical at -55°C to 175°C.

Q: What is the moisture sensitivity level for both parts?

A: Both the 5KP250C and 5KP250CA have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are export control classifications the same?

A: Yes. Both parts are classified as EAR99 for export control purposes and share identical HTSUS tariff classification (8541.10.0080).
