Substitute Part Grouping Explanation

Substitution eligibility for the TPSMP13AHM3/85A is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 11.1V
• Voltage - Breakdown (Min): 12.4V
• Voltage - Clamping (Max) @ Ipp: 18.2V
• Current - Peak Pulse (10/1000µs): 22A
• Power - Peak Pulse: 400W
• 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 TPSMP13AHM3_A/I maintains identical electrical specifications and mechanical compatibility while differing only in packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The TPSMP13AHM3_A/I is a direct functional equivalent to the obsolete TPSMP13AHM3/85A. Both parts are manufactured by Vishay and carry identical electrical and thermal specifications. The primary distinction is product status: TPSMP13AHM3_A/I is currently active in production, ensuring long-term availability and supply chain continuity.

Both parts maintain AEC-Q101 automotive qualification and ROHS3 compliance, satisfying regulatory requirements for automotive-grade transient voltage suppression applications. The packaging difference (Tape & Reel for the substitute versus bulk for the original) does not affect electrical performance or mechanical fit in surface-mount assemblies.

Frequently Asked Questions (FAQ)

Q: Can TPSMP13AHM3_A/I be used as a direct replacement for TPSMP13AHM3/85A?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters: voltage ratings, current capacity, power dissipation, package type, and operating temperature range. The substitute is the active production equivalent.

Q: What is the difference between the two part numbers?

A: The TPSMP13AHM3/85A is obsolete, while TPSMP13AHM3_A/I is active. The suffix difference reflects packaging format: the substitute is supplied in Tape & Reel format for automated assembly, whereas the original was available in bulk packaging.

Q: Are both parts qualified for automotive applications?

A: Yes. Both parts carry AEC-Q101 automotive qualification and are rated for the automotive temperature range of -65°C to 185°C (junction temperature).

Q: Do the parts have identical clamping characteristics?

A: Yes. Both parts specify 18.2V maximum clamping voltage at peak pulse current (22A, 10/1000µs waveform) and 400W peak pulse power dissipation.

Q: Is the DO-220AA package the same for both parts?

A: Yes. Both parts use the DO-220AA (SMP) surface-mount package with identical mechanical dimensions and land pattern requirements.

Q: Are there any compliance differences between the parts?

A: No. Both parts are ROHS3 compliant and carry identical regulatory certifications.
