Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5KP15CA-TP are identified based on the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Voltage - Reverse Standoff (Typ): 15V
• Voltage - Breakdown (Min): 16.6V–16.7V
• Power - Peak Pulse: 5000W (5kW)
• Bidirectional Channels: 1
• Mounting Type: Through Hole
• Package / Case: Axial configuration (R-6 or equivalent)
• RoHS3 Compliance
• MSL Rating: 1 (Unlimited)

Substitute Classification:

Direct Equivalent: 5KP15CA (Littelfuse Inc.) — Identical electrical specifications, same series base product number (5KP), matching voltage ratings, clamping voltage, and power dissipation. Package designation differs (P600 vs. R-6) but both are axial through-hole configurations.

Similar Substitute: BZW50-15B (STMicroelectronics) — Matches core voltage parameters (15V reverse standoff, 16.6V breakdown minimum) and 5000W peak pulse power. Differs in clamping voltage (35V vs. 24.4V) and peak pulse current specification. Same axial through-hole mounting and R-6 package. Suitable where higher clamping voltage is acceptable.

Engineering Selection Recommendations

5KP15CA (Littelfuse Inc.) — Direct Equivalent

This part is the primary substitute for the 5KP15CA-TP. It maintains identical electrical performance across all critical parameters: 15V reverse standoff voltage, 16.7V breakdown minimum, and 24.4V clamping voltage at peak pulse current. Both parts share the same 5KP series base product number and deliver 5000W peak pulse power dissipation. The package designation differs (P600 vs. R-6), but both are axial through-hole configurations suitable for standard PCB mounting. All compliance certifications align: ROHS3 compliant, MSL 1 (Unlimited), and active product status. This substitute provides direct functional equivalence with 3738 units in stock.

BZW50-15B (STMicroelectronics) — Similar Substitute

This part qualifies as a similar substitute based on matching voltage protection parameters (15V reverse standoff, 16.6V breakdown minimum) and identical 5000W peak pulse power rating. The primary difference is the clamping voltage specification: 35V versus 24.4V. This higher clamping voltage may be acceptable in applications where transient suppression at a higher voltage threshold is tolerable or beneficial. The BZW50-15B uses the same R-6 axial through-hole package as the main part, ensuring mechanical compatibility. All compliance requirements are met: ROHS3 compliant, MSL 1 (Unlimited), and active product status. Selection of this substitute requires confirmation that the 35V clamping voltage does not exceed circuit protection requirements. This part has 2244 units in stock.

Frequently Asked Questions (FAQ)

Q: Can I use the 5KP15CA as a direct replacement for the 5KP15CA-TP?

A: Yes. The 5KP15CA is a direct equivalent. Both parts share identical electrical specifications for reverse standoff voltage (15V), breakdown voltage (16.7V), and clamping voltage (24.4V). The package designation differs (P600 vs. R-6), but both are axial through-hole configurations. All compliance certifications and operating temperature ranges match.

Q: What is the key difference between the 5KP15CA-TP and the BZW50-15B?

A: The primary difference is the clamping voltage. The 5KP15CA-TP clamps at 24.4V maximum, while the BZW50-15B clamps at 35V. Both maintain the same 15V reverse standoff voltage and 5000W peak pulse power rating. The BZW50-15B is suitable only if the higher clamping voltage is compatible with your circuit protection scheme.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The 5KP15CA and BZW50-15B are both ROHS3 compliant, matching the compliance status of the 5KP15CA-TP.

Q: Do the substitute parts have the same moisture sensitivity level?

A: Yes. Both the 5KP15CA and BZW50-15B carry MSL 1 (Unlimited) rating, identical to the main part.

Q: Can I use the BZW50-15B in place of the 5KP15CA-TP without circuit modifications?

A: The BZW50-15B can be used mechanically and electrically, but the 35V clamping voltage differs from the 24.4V specification of the 5KP15CA-TP. Verify that your circuit protection requirements accommodate this higher clamping threshold before substitution.

Q: What is the operating temperature range for the BZW50-15B?

A: The operating temperature range for the BZW50-15B is not specified in the provided data. The 5KP15CA-TP and 5KP15CA both operate across -55°C to 175°C (TJ).

Q: Are the package dimensions identical between R-6 and P600 axial packages?

A: Both R-6 and P600 are axial through-hole packages designations. Physical dimensions may differ between manufacturers. Verify mechanical compatibility with your PCB layout and component footprint before substitution.

Q: Which substitute part has the highest inventory availability?

A: The 5KP15CA (Littelfuse Inc.) has 3738 units in stock, compared to 2244 units for the BZW50-15B and 1268 units for the main part 5KP15CA-TP.
