Compliance Requirements:

• RoHS3 Compliant
• Active product status

Parameter Comparison

Engineering Selection Recommendations

P6KE8.2CA (Direct Substitute): This part is manufactured by Taiwan Semiconductor Corporation and maintains identical electrical specifications to the P6KE8.2CA-TP across all critical parameters. Peak pulse current is marginally higher at 52A versus 50A, providing equivalent or superior performance. Both parts share identical voltage ratings, power dissipation, temperature range, and package configuration. This substitute is recommended as a primary alternative due to specification parity and active product status with high inventory availability (30400 pcs).

SA7.0CA-E3/54 (Similar Substitute): This Vishay TransZorb® component operates within acceptable electrical tolerances for the P6KE8.2CA-TP application. The reverse standoff voltage is 7.0V (0.02V lower), clamping voltage is 12.0V (0.1V lower), and peak pulse current is 41.7A (8.3A lower). Power dissipation is 500W versus 600W. All parameters remain within functional compatibility for general-purpose TVS applications. This substitute is suitable where inventory or supply constraints necessitate alternative sourcing, with the understanding that peak pulse current capacity is reduced. Active product status and RoHS3 compliance are maintained.

Frequently Asked Questions (FAQ)

Q: Can P6KE8.2CA be used as a direct replacement for P6KE8.2CA-TP?

A: Yes. The P6KE8.2CA maintains identical electrical specifications across voltage ratings, clamping characteristics, and operating temperature range. The 52A peak pulse current exceeds the 50A requirement of the main part. Both components use DO-15 through-hole packaging and are RoHS3 compliant.

Q: What are the limitations of using SA7.0CA-E3/54 as a substitute?

A: The SA7.0CA-E3/54 operates within acceptable electrical tolerances but with reduced peak pulse current capacity (41.7A versus 50A) and lower power dissipation (500W versus 600W). The reverse standoff and clamping voltages are marginally lower. This substitute is suitable for applications where peak transient current demands do not exceed 41.7A.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All three parts use DO-204AC (DO-15) axial through-hole packaging, ensuring mechanical and footprint compatibility on existing circuit board designs.

Q: Do substitute parts maintain the same compliance certifications?

A: Yes. All substitute parts are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99, matching the compliance profile of the P6KE8.2CA-TP.

Q: Which substitute should be selected for new designs?

A: Selection depends on supply availability and application requirements. The P6KE8.2CA is recommended for specification parity. The SA7.0CA-E3/54 is suitable where peak pulse current requirements are confirmed below 41.7A and power dissipation does not exceed 500W.
