Engineering Selection Recommendations
30KPA30CA (Direct Equivalent): This part is the primary substitute for the 30KP30CA-TP. Both components share identical electrical specifications (30V standoff, 55.2V clamping, 30kW power rating) and full ROHS3 compliance. The only difference is packaging format and manufacturer. This substitute is suitable for direct replacement in applications where the original part is unavailable.
15KPA30CA (Similar Substitute): This part maintains the 30V standoff voltage and full operating temperature range (-55°C to 175°C) with ROHS3 compliance. It is suitable for applications where peak transient energy is limited to 15kW or lower. The reduced clamping voltage (50.7V) and peak pulse current (297.8A) must be evaluated against circuit protection requirements.
5KP30CA (Similar Substitute): This part maintains the 30V standoff voltage with ROHS3 compliance. It is suitable only for low-energy transient protection applications with peak pulse power limited to 5kW. The minimum operating temperature is -50°C (versus -55°C for the main part), which may be a limiting factor in extreme cold environments. The reduced clamping voltage (48.4V) and peak pulse current (103A) require circuit-level evaluation.
All substitute parts are active production components with established supply availability and full regulatory compliance documentation.
Frequently Asked Questions (FAQ)
Q: Can 30KPA30CA be used as a direct replacement for 30KP30CA-TP?
A: Yes. Both parts have identical electrical specifications: 30V reverse standoff voltage, 55.2V clamping voltage, and 30kW peak pulse power rating. Both are ROHS3 compliant and rated for -55°C to 175°C operation. The difference is packaging format (Bulk vs. Tape & Reel) and manufacturer. Verify that your procurement and assembly processes accommodate the different packaging.
Q: What is the difference between the 30KP30CA-TP and 15KPA30CA?
A: The 15KPA30CA has half the peak pulse power rating (15kW vs. 30kW) and a lower clamping voltage (50.7V vs. 55.2V). Both maintain the 30V standoff voltage and full operating temperature range. Use 15KPA30CA only if your circuit transient energy is confirmed to be below 15kW.
Q: Can 5KP30CA replace 30KP30CA-TP in all applications?
A: No. The 5KP30CA has significantly lower peak pulse power (5kW vs. 30kW), lower clamping voltage (48.4V vs. 55.2V), and a higher minimum operating temperature (-50°C vs. -55°C). Use 5KP30CA only for low-energy transient protection where peak pulse power does not exceed 5kW and minimum operating temperature is above -50°C.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All listed substitute parts (30KPA30CA, 15KPA30CA, and 5KP30CA) are ROHS3 compliant, matching the compliance status of the 30KP30CA-TP.
Q: What is the difference between R-6 and P600 package formats?
A: R-6 and P600 are both axial through-hole packages for TVS diodes. The difference is in physical dimensions and lead configuration. Verify that your PCB footprint and assembly equipment are compatible with the substitute part's package format before procurement.
Q: Do all substitute parts have the same operating temperature range?
A: No. The 30KPA30CA and 15KPA30CA are rated -55°C to 175°C, matching the main part. The 5KP30CA is rated -50°C to 175°C, with a higher minimum temperature limit. This may be a constraint in applications requiring operation below -50°C.
Q: What inventory levels are available for each substitute?
A: 30KPA30CA: 1705 pcs; 15KPA30CA: 1200 pcs; 5KP30CA: 4100 pcs. Inventory levels are subject to change and should be confirmed with the supplier.
