Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPC10HM3/87A is determined by strict alignment of the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Unidirectional channel configuration (1 channel required)
• Reverse standoff voltage range (8.1V nominal)
• Breakdown voltage minimum (9V)
• Clamping voltage at peak pulse current (15V maximum)
• Peak pulse current capability (100A minimum)
• Peak pulse power dissipation (1500W)
• Surface mount package compatibility (TO-277A SMPC)
• Automotive grade qualification (AEC-Q101)
• Operating temperature range (-65°C ~ 185°C)

The substitute part TPC10AHM3_A/I meets these criteria while offering active product status, ensuring long-term availability and manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

The TPC10AHM3_A/I is the qualified substitute for the obsolete TPC10HM3/87A. Both components share identical automotive grade classification and AEC-Q101 qualification, ensuring compliance with automotive reliability standards. The substitute maintains the same package footprint (TO-277A SMPC), operating temperature range, and power dissipation capability.

The TPC10AHM3_A/I offers the additional advantage of active product status, providing assured long-term availability and manufacturing support. Electrical parameters remain within acceptable tolerance bands for transient voltage suppression applications. The substitute is supplied in Tape & Reel packaging, suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can TPC10AHM3_A/I be used as a direct replacement for TPC10HM3/87A?

A: Yes. Both components are unidirectional TVS diodes with identical package geometry (TO-277A SMPC), operating temperature range, and power dissipation specifications. Electrical parameters are within acceptable tolerance for the same application circuit.

Q: What are the key electrical differences between these parts?

A: The substitute exhibits slightly higher reverse standoff voltage (8.55V vs. 8.1V), breakdown voltage (9.5V vs. 9V), and marginally higher peak pulse current (103A vs. 100A). The clamping voltage is 14.5V versus 15V. These variations remain within the functional tolerance for transient suppression circuits.

Q: Are both parts qualified for automotive applications?

A: Yes. Both the TPC10HM3/87A and TPC10AHM3_A/I carry automotive grade classification and AEC-Q101 qualification, meeting automotive reliability and quality standards.

Q: What is the packaging difference?

A: The main part is listed as new original stock without specified packaging. The substitute is supplied in Tape & Reel (TR) format, which is standard for automated surface mount assembly.

Q: Why is the main part listed as obsolete?

A: The TPC10HM3/87A is classified as obsolete by the manufacturer. The TPC10AHM3_A/I is the active equivalent, ensuring continued availability and manufacturing support for new designs and production continuity.

Q: Are moisture sensitivity levels the same?

A: Yes. Both components have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.
