Substitute Part Grouping Explanation
Substitution eligibility for the 15KP28CA-TP is determined by the following critical parameters: reverse standoff voltage (28V), bidirectional channel configuration (1 channel), zener type classification, through-hole mounting, and general-purpose application category. All identified substitute parts maintain the 28V reverse standoff voltage specification, which is the primary electrical constraint for circuit protection compatibility. Substitute parts are grouped based on power rating capability and package configuration variations. The 15KPA28CA and 30KPA28CA-B represent higher-performance alternatives with increased peak pulse current handling. The 5KP28CA and 5KP28CA-B represent lower-power alternatives suitable for applications with reduced transient energy requirements. All substitute parts maintain the operating temperature range of -55°C to 175°C and are classified as active products with current manufacturing availability.

Engineering Selection Recommendations
The 15KPA28CA provides direct electrical equivalence to the 15KP28CA-TP with identical 28V reverse standoff voltage, 47.5V clamping voltage, and 15kW peak pulse power rating. This part is manufactured by MDE Semiconductor Inc and maintains ROHS3 compliance. The primary difference is packaging configuration (P600 versus R-6) and supplier device package designation.
The 30KPA28CA-B, manufactured by Littelfuse Inc., maintains the 28V reverse standoff voltage but offers increased power handling capability at 30kW peak pulse power with 606A peak pulse current. This part is suitable for applications requiring higher transient energy dissipation while maintaining the same voltage protection threshold. ROHS3 compliance and active product status are confirmed.
The 5KP28CA and 5KP28CA-B are lower-power alternatives rated at 5kW peak pulse power. Both maintain the 28V reverse standoff voltage and are suitable for circuits with reduced transient energy requirements. The 5KP28CA-B, manufactured by Littelfuse Inc., is ROHS3 compliant with confirmed active status. The 5KP28CA, manufactured by Diotec Semiconductor, has RoHS status listed as not applicable and maintains active product status.
All substitute parts are through-hole mounted components with axial package configurations and operate within the -55°C to 175°C temperature range, with the exception of the 5KP28CA which specifies -50°C minimum operating temperature.
Frequently Asked Questions (FAQ)
Q: What is the primary criterion for substituting the 15KP28CA-TP? A: The 28V reverse standoff voltage is the primary electrical parameter determining substitution eligibility. All substitute parts maintain this specification to ensure equivalent circuit protection performance.
Q: Can the 30KPA28CA-B be used as a direct replacement for the 15KP28CA-TP? A: The 30KPA28CA-B maintains the 28V reverse standoff voltage and clamping voltage specifications but offers increased power handling at 30kW versus 15kW. It is electrically compatible for overvoltage protection but provides enhanced transient energy dissipation capability. Package configuration differs (P600 versus R-6).
Q: What is the difference between the 15KPA28CA and the 15KP28CA-TP? A: Both parts share identical electrical specifications: 28V reverse standoff voltage, 47.5V clamping voltage, and 15kW peak pulse power rating. The primary differences are manufacturer (MDE Semiconductor Inc versus Micro Commercial Co), packaging configuration (P600 versus R-6), and supplier device package designation.
Q: Are the 5KP28CA and 5KP28CA-B suitable replacements for the 15KP28CA-TP? A: The 5KP28CA and 5KP28CA-B maintain the 28V reverse standoff voltage but are rated at 5kW peak pulse power compared to the 15kW rating of the 15KP28CA-TP. These parts are suitable only for applications with lower transient energy requirements.
Q: What packaging differences exist among the substitute parts? A: The 15KP28CA-TP uses R-6 axial package configuration. The 15KPA28CA, 30KPA28CA-B, 5KP28CA, and 5KP28CA-B all use P600 axial package configuration. Physical dimensions and PCB footprints differ between R-6 and P600 packages.
Q: Are all substitute parts ROHS3 compliant? A: The 15KPA28CA, 30KPA28CA-B, and 5KP28CA-B are ROHS3 compliant. The 5KP28CA has RoHS status listed as not applicable. The 15KP28CA-TP is ROHS3 compliant.
Q: What is the operating temperature range for all parts? A: The 15KP28CA-TP, 15KPA28CA, 30KPA28CA-B, and 5KP28CA-B operate from -55°C to 175°C. The 5KP28CA operates from -50°C to 175°C, with a 5°C higher minimum temperature specification.
