Engineering Selection Recommendations
Primary Substitutes (Full Electrical and Mechanical Equivalence):
P6KE15A-TP (Micro Commercial Co) and P6KE15A-AP (Micro Commercial Co) are direct substitutes with identical electrical specifications, operating temperature range matching the original part, and active product status. Both are RoHS3 compliant and available in standard inventory quantities.
P6KE15A TR PBFREE (Central Semiconductor Corp) provides equivalent electrical performance with extended lower operating temperature capability (-65°C minimum) and active status. RoHS3 compliance is confirmed.
Secondary Substitutes (Minor Parameter Variations):
P6KE15A (Fairchild Semiconductor) offers 29A peak pulse current, exceeding the 28A requirement, with active status. Operating temperature minimum is -50°C versus -55°C on the original part. Suitable for applications not requiring the full lower temperature range.
P6KE15A-B (Littelfuse Inc.) provides 28.8A peak pulse current with full temperature range equivalence (-55°C ~ 175°C) and active status. Manufacturer-recommended substitute designation. RoHS3 and REACH compliant.
P6KE15A-G (Comchip Technology) delivers 28.3A peak pulse current with active status and RoHS3 compliance. Operating temperature maximum is 150°C versus 175°C on the original part. Suitable for applications with maximum operating temperature below 150°C.
P6KE15AE3/TR13 (Microsemi Corporation) maintains full electrical equivalence in axial package format with active status. Operating temperature maximum is 150°C. Suitable for applications accepting the reduced upper temperature limit.
Packaging Consideration:
All substitute parts are available in DO-15 or DO-204AC through-hole axial configuration, maintaining mechanical compatibility with the original P6KE15A-T footprint.
Frequently Asked Questions (FAQ)
Q: Can I use P6KE15A (Fairchild) as a direct replacement for P6KE15A-T?
A: Yes. The Fairchild P6KE15A meets all critical electrical parameters with 29A peak pulse current (exceeding the 28A requirement) and identical voltage specifications. The operating temperature minimum is -50°C versus -55°C on the original part. This substitution is suitable unless your application requires operation below -50°C.
Q: What is the difference between P6KE15A-TP, P6KE15A-AP, and P6KE15A-BP?
A: All three are manufactured by Micro Commercial Co with identical electrical specifications (12.8V standoff, 21.2V clamping, 28A peak pulse). The suffix designates packaging format: -TP is Cut Tape (CT), -AP and -BP are Bulk. Select based on your procurement and assembly requirements.
Q: Is P6KE15A-B from Littelfuse a suitable substitute?
A: Yes. The P6KE15A-B is designated as a manufacturer-recommended substitute with 28.8A peak pulse current (exceeding the 28A minimum), full temperature range equivalence (-55°C ~ 175°C), and active product status. RoHS3 and REACH compliance are confirmed.
Q: Can I use P6KE15A-G if my application operates at temperatures above 150°C?
A: No. The P6KE15A-G has a maximum operating temperature of 150°C, while the original P6KE15A-T is rated to 175°C. Use this substitute only if your maximum operating temperature does not exceed 150°C.
Q: What is the difference between DO-15 and DO-204AC packaging?
A: DO-15 and DO-204AC are equivalent designations for the same through-hole axial diode package. Both terms refer to the same physical form factor and are mechanically interchangeable.
Q: Are all substitute parts RoHS3 compliant?
A: All listed substitute parts are RoHS3 compliant. Verify REACH status with your supplier if REACH compliance is a requirement for your application.
Q: Can I substitute P6KE15AE3/TR13 in a standard DO-15 footprint?
A: Yes. The P6KE15AE3/TR13 is supplied in axial package format (T-18), which is mechanically compatible with standard DO-15 through-hole footprints. Note that the maximum operating temperature is 150°C.
