Substitute Part Grouping Explanation

Substitute parts for the AR1FD-M3/I are identified based on strict electrical and mechanical parameter equivalence. The following criteria determine substitution eligibility:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 200 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.25 V @ 1 A
• Reverse Recovery Time (trr): 140 ns
• Current - Reverse Leakage @ Vr: 1 µA @ 200 V
• Capacitance @ Vr, F: 12.6 pF @ 4V, 1MHz
• Operating Temperature - Junction: -55°C to 175°C

Mechanical Parameters (Must Match):

• Package / Case: DO-219AB (SMF)
• Mounting Type: Surface Mount
• Technology: Avalanche

Compliance Parameters (Must Match):

• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

Variable Parameters (Allowed to Differ):

• Packaging format (Tape & Reel vs. Cut Tape)
• Moisture Sensitivity Level (MSL)

The identified substitutes maintain complete electrical and mechanical equivalence while offering alternative packaging configurations suitable for different procurement and assembly workflows.

Parameter Comparison

Engineering Selection Recommendations

All three parts—AR1FD-M3/I, AR1FD-M3/H, and AR1FDHM3/H—are electrically and mechanically equivalent avalanche rectifier diodes with identical performance specifications. Selection between these parts is determined by packaging format and supply availability rather than functional capability.

AR1FD-M3/I (Tape & Reel): Suitable for high-volume automated assembly operations requiring continuous reel-fed component supply. Tape & Reel packaging optimizes pick-and-place machine compatibility and reduces manual handling.

AR1FD-M3/H (Cut Tape): Suitable for lower-volume production runs, prototype development, and manual assembly workflows. Cut Tape format provides flexibility for mixed-component procurement without committing to full reel quantities.

AR1FDHM3/H (Cut Tape): Functionally identical to AR1FD-M3/H with equivalent Cut Tape packaging. Selection between AR1FD-M3/H and AR1FDHM3/H is based on supplier availability and procurement lead times.

All parts maintain automotive-grade qualification under AEC-Q101 standard and comply with ROHS3 and REACH regulatory requirements, ensuring suitability for automotive and industrial applications requiring environmental compliance certification.

Frequently Asked Questions (FAQ)

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

A: Yes. All three parts are electrically and mechanically equivalent. The only difference is packaging format (Tape & Reel versus Cut Tape). Direct substitution is valid provided the assembly process can accommodate the alternative packaging format.

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, optimized for automated pick-and-place assembly. Cut Tape packaging supplies the same components on shorter tape segments, suitable for manual handling and lower-volume assembly. Both formats contain identical components in the same DO-219AB package.

Q: Are there any electrical performance differences between AR1FD-M3/I, AR1FD-M3/H, and AR1FDHM3/H?

A: No. All three parts have identical electrical specifications including reverse voltage rating (200 V), forward current (1 A), forward voltage drop (1.25 V @ 1 A), reverse recovery time (140 ns), and reverse leakage current (1 µA @ 200 V).

Q: Do all three parts meet automotive qualification requirements?

A: Yes. All parts are automotive-grade components qualified to AEC-Q101 standard and comply with ROHS3 and REACH regulatory requirements.

Q: What is the Moisture Sensitivity Level (MSL) for AR1FD-M3/I?

A: The MSL specification is not provided for AR1FD-M3/I. AR1FD-M3/H and AR1FDHM3/H are specified with MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.

Q: Can these parts be used interchangeably in the same circuit design?

A: Yes. The identical electrical and mechanical specifications ensure functional interchangeability across all three part numbers in any circuit application designed for the AR1FD-M3/I.

Q: Which part should be selected for new design implementations?

A: Selection depends on manufacturing process requirements. For automated high-volume assembly, AR1FD-M3/I (Tape & Reel) is appropriate. For prototype development, manual assembly, or lower-volume production, AR1FD-M3/H or AR1FDHM3/H (Cut Tape) are suitable. All parts deliver identical electrical performance.
