Substitute Part Grouping Explanation

Substitution of the TPSMP10AHM3/84A is determined by strict equivalence across the following critical electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 8.55V
• Voltage - Breakdown (Min): 9.5V
• Voltage - Clamping (Max) @ Ipp: 14.5V
• Current - Peak Pulse (10/1000µs): 20.7A
• Unidirectional Channels: 1
• Package / Case: DO-220AA (SMP)
• Mounting Type: Surface Mount
• Operating Temperature Range: -65°C ~ 185°C (TJ)
• Grade: Automotive
• Qualification: AEC-Q101

The substitute part TPSMP10AHM3_A/H maintains identical electrical specifications and automotive qualification requirements. The primary distinction is packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete), with a minor increase in peak pulse power rating (400W versus 300W), which represents an enhancement rather than a deviation from the original specification.

Parameter Comparison

Engineering Selection Recommendations

The TPSMP10AHM3_A/H is a direct functional equivalent to the TPSMP10AHM3/84A. Both components share identical electrical performance specifications, automotive-grade classification, and AEC-Q101 qualification. The substitute part is currently in active production status, whereas the original part is obsolete.

Selection of TPSMP10AHM3_A/H is appropriate for applications requiring the specified voltage protection characteristics (8.55V standoff, 14.5V clamping) and automotive-grade reliability. The increased peak pulse power rating (400W versus 300W) provides additional thermal margin without altering the protection threshold or response characteristics.

Packaging format differences (Tape & Reel for the substitute versus bulk for the original) affect procurement and assembly processes but do not impact electrical or mechanical compatibility in the DO-220AA surface mount package.

Frequently Asked Questions (FAQ)

Q: Can TPSMP10AHM3_A/H be used as a direct replacement for TPSMP10AHM3/84A?

A: Yes. Both parts maintain identical electrical specifications across all critical parameters: 8.55V reverse standoff voltage, 9.5V minimum breakdown voltage, 14.5V maximum clamping voltage, and 20.7A peak pulse current. Both are automotive-grade with AEC-Q101 qualification and use the same DO-220AA surface mount package.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The original part (TPSMP10AHM3/84A) is classified as obsolete, indicating discontinued production. The substitute (TPSMP10AHM3_A/H) is in active production, ensuring ongoing availability for new designs and system support.

Q: Does the packaging format difference affect circuit performance?

A: No. The packaging format difference (Tape & Reel versus bulk) is a procurement and assembly consideration only. Both formats contain identical components in the DO-220AA surface mount package with no impact on electrical performance or circuit compatibility.

Q: Why is the peak pulse power rating higher for the substitute part?

A: The substitute part (TPSMP10AHM3_A/H) has a 400W peak pulse power rating compared to 300W for the original. This represents an enhancement that provides additional thermal margin during transient events while maintaining all other electrical specifications unchanged.

Q: Are both parts compliant with automotive and environmental standards?

A: Yes. Both TPSMP10AHM3/84A and TPSMP10AHM3_A/H are automotive-grade components with AEC-Q101 qualification, ROHS3 compliance, and MSL 1 (Unlimited) moisture sensitivity rating.
