Engineering Selection Recommendations

15KPA110CA (MDE Semiconductor Inc)

This substitute maintains all critical electrical parameters with Active product status, ensuring long-term availability. The part is ROHS3 compliant and available in Bulk packaging. The voltage clamping specification of 178.6V is within acceptable tolerance for applications designed for the original 15KPA110C. Moisture Sensitivity Level (MSL) rating of 1 (Unlimited) provides flexibility in storage and handling conditions.

15KPA110CE3/TR13 (Microchip Technology)

This substitute is supplied in Tape & Reel (TR) packaging format, suitable for automated assembly processes. The part maintains Active product status with ROHS3 compliance and REACH Unaffected status. Voltage breakdown specification of 115.83V matches the original part exactly. This option is appropriate for high-volume production environments requiring tape and reel delivery.

Frequently Asked Questions (FAQ)

Q: Can 15KPA110CA be used as a direct replacement for 15KPA110C?

A: Yes. Both parts share identical reverse standoff voltage (110V), peak pulse power (15kW), operating temperature range (-55°C ~ 175°C), package type (P600, Axial), and mounting configuration (Through Hole). The voltage clamping specification of 178.6V for the 15KPA110CA is within acceptable operating parameters for circuits designed for the original 15KPA110C.

Q: What is the difference between 15KPA110CA and 15KPA110CE3/TR13?

A: The primary difference is packaging format. The 15KPA110CA is supplied in Bulk packaging, while 15KPA110CE3/TR13 is supplied in Tape & Reel (TR) format. Both maintain identical reverse standoff voltage and peak pulse power specifications. Selection depends on assembly method: Bulk for manual or semi-automated processes, Tape & Reel for fully automated assembly lines.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The 15KPA110C, 15KPA110CA, and 15KPA110CE3/TR13 are all ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing and use.

Q: Why is the original 15KPA110C listed as Obsolete?

A: Obsolete status indicates the part is no longer manufactured by Littelfuse Inc. The substitute parts listed maintain equivalent electrical and mechanical specifications, providing continuity for applications currently using the 15KPA110C.

Q: Can I mix substitute parts in the same circuit board assembly?

A: Yes. Both substitute parts meet the same electrical and mechanical specifications for the 15KPA110C. However, packaging format differences (Bulk vs. Tape & Reel) may affect assembly logistics and should be coordinated with manufacturing processes.
