Engineering Selection Recommendations

AR4PDHM3_A/I is recommended as the primary substitute for the discontinued AR4PDHM3/87A. This part maintains identical electrical specifications and is supplied in Tape & Reel packaging. The AR4PDHM3_A/I carries automotive grade qualification (AEC-Q101) and active product status, ensuring long-term availability and supply chain stability.

AR4PD-M3/87A provides an alternative with identical electrical performance and active product status. This part is supplied in Tape & Reel format and is suitable for applications requiring standard industrial-grade components.

AR4PD-M3/86A is a parametric equivalent supplied in Cut Tape packaging. This part maintains all electrical specifications and is appropriate for applications where Cut Tape format is acceptable. Active product status ensures continued availability.

AR4PDHM3_A/H is an automotive-qualified alternative with AEC-Q101 certification and active product status. This part is supplied in Tape & Reel format and is suitable for automotive applications requiring qualified components.

All substitute parts are ROHS3 compliant, REACH unaffected, and maintain MSL 1 (Unlimited) moisture sensitivity classification. Selection between alternatives should be based on packaging format requirements (Tape & Reel versus Cut Tape) and automotive qualification needs.

Frequently Asked Questions (FAQ)

Q: Can AR4PDHM3_A/I be used as a direct replacement for AR4PDHM3/87A?

A: Yes. The AR4PDHM3_A/I is electrically and mechanically equivalent to the AR4PDHM3/87A across all critical parameters including voltage rating, current capacity, forward voltage drop, reverse recovery time, and package configuration. The primary difference is product status (active versus discontinued) and packaging format (Tape & Reel).

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, suitable for automated assembly processes. Cut Tape packaging supplies the same components on cut sections of carrier tape, suitable for manual assembly or smaller volume applications. Both formats contain identical components with the same electrical specifications.

Q: Are the automotive-qualified variants (AR4PDHM3_A/I and AR4PDHM3_A/H) required for non-automotive applications?

A: No. Automotive qualification (AEC-Q101) is not required for non-automotive applications. The standard industrial-grade alternatives (AR4PD-M3/87A and AR4PD-M3/86A) provide identical electrical performance and are suitable for general industrial use. Automotive-qualified parts may be selected when supply chain or application requirements specify AEC-Q101 certification.

Q: Do all substitute parts have the same operating temperature range?

A: Yes. All substitute parts maintain the same junction temperature operating range of -55°C to 175°C, ensuring thermal performance equivalence across all alternatives.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity classification. These certifications are consistent across all alternatives and the original part.

Q: Can AR4PD-M3/86A be substituted for AR4PDHM3/87A in existing designs?

A: Yes. The AR4PD-M3/86A is a parametric equivalent with identical electrical specifications and the same TO-277, 3-PowerDFN package configuration. The only difference is packaging format (Cut Tape versus the original format). This part is suitable for replacement in existing designs where Cut Tape format is acceptable.
