AR1FDHM3/I Equivalent & Substitute Parts

Part Overview

The AR1FDHM3/I is an avalanche diode manufactured by Vishay General Semiconductor - Diodes Division, rated for 200 V DC reverse voltage and 1 A average rectified current in a DO-219AB surface mount package. This component is classified as an active product with automotive-grade qualification (AEC-Q101) and full RoHS3 compliance. The part is supplied in Tape & Reel (TR) packaging format.

Substitute parts become necessary when the original packaging format is unavailable, inventory constraints exist, or alternative supplier configurations are required while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the AR1FDHM3/I is based on strict equivalence across all critical electrical and mechanical parameters. The substitute parts AR1FD-M3/H and AR1FDHM3/H are classified as parametric equivalents because they maintain identical specifications in the following key areas:

• Reverse voltage rating: 200 V
• Average rectified current: 1 A
• Forward voltage drop: 1.25 V @ 1 A
• Reverse recovery time: 140 ns
• Reverse leakage current: 1 µA @ 200 V
• Junction capacitance: 12.6 pF @ 4V, 1MHz
• Operating temperature range: -55°C to 175°C
• Package type: DO-219AB surface mount
• Technology classification: Avalanche diode
• Automotive grade with AEC-Q101 qualification
• RoHS3 compliance and REACH unaffected status

The primary distinction between the main part and substitutes is the packaging format: the AR1FDHM3/I is supplied in Tape & Reel (TR) configuration, while AR1FD-M3/H and AR1FDHM3/H are supplied in Cut Tape (CT) format. Both packaging formats are suitable for automated assembly processes and contain identical component specifications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—AR1FDHM3/I, AR1FD-M3/H, and AR1FDHM3/H—are active products manufactured by Vishay General Semiconductor - Diodes Division with identical electrical and mechanical specifications. Selection between these parts is determined by packaging format requirements and inventory availability.

The AR1FDHM3/I in Tape & Reel format is suitable for high-volume automated assembly operations where continuous reel feeding is required. The AR1FD-M3/H and AR1FDHM3/H in Cut Tape format are suitable for lower-volume production runs, kit assembly, or applications where individual component handling is preferred.

All three parts carry automotive-grade classification with AEC-Q101 qualification, confirming suitability for automotive applications. RoHS3 compliance and REACH unaffected status ensure regulatory compliance across global markets. The identical operating temperature range of -55°C to 175°C supports deployment in both industrial and automotive thermal environments.

Frequently Asked Questions (FAQ)

Q: Can AR1FD-M3/H or AR1FDHM3/H be used as direct replacements for AR1FDHM3/I in production?

A: Yes. All three parts are parametric equivalents with identical electrical specifications, reverse voltage ratings, current ratings, forward voltage characteristics, and reverse recovery times. The only difference is packaging format (Tape & Reel versus Cut Tape). Direct substitution is valid from an electrical and mechanical standpoint.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel packaging supplies components on a continuous reel suitable for automated pick-and-place assembly systems. Cut Tape packaging supplies components on tape segments, typically used for lower-volume assembly, manual handling, or kit configurations. Both formats use identical DO-219AB surface mount packages and contain the same component specifications.

Q: Are all three parts suitable for automotive applications?

A: Yes. AR1FDHM3/I, AR1FD-M3/H, and AR1FDHM3/H all carry automotive-grade classification with AEC-Q101 qualification. This certification confirms compliance with automotive industry reliability and quality standards.

Q: Do the substitute parts meet the same regulatory requirements as the main part?

A: Yes. All three parts are RoHS3 compliant and REACH unaffected. Both AR1FD-M3/H and AR1FDHM3/H carry identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications as the AR1FDHM3/I.

Q: What is the Moisture Sensitivity Level (MSL) for the substitute parts?

A: Both AR1FD-M3/H and AR1FDHM3/H have an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can these parts be used interchangeably in circuit designs?

A: Yes. The identical electrical parameters—200 V reverse voltage, 1 A average rectified current, 1.25 V forward voltage drop, 140 ns reverse recovery time, and 1 µA reverse leakage current—ensure functional equivalence in all circuit applications. No circuit redesign or component requalification is required when substituting between these parts.

Q: What inventory levels are available for each part?

A: AR1FDHM3/I (Tape & Reel) has 1016 pieces in stock. AR1FD-M3/H (Cut Tape) has 18645 pieces in stock. AR1FDHM3/H (Cut Tape) has 19080 pieces in stock.
