ACGRMS4007-HF Equivalent & Substitute Parts

Part Overview

The ACGRMS4007-HF is a general-purpose rectifier diode manufactured by Comchip Technology, rated for 1000 V DC reverse voltage and 1 A average rectified current in a surface mount SOD-123F package. This component is classified as Active product status and carries automotive-grade qualification (AEC-Q101) with ROHS3 compliance.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameter set. The ACGRMS4007-HF remains in active production; however, alternative sources may be required due to supply chain considerations, inventory availability, or design flexibility requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ACGRMS4007-HF are qualified based on strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 1000 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1 A
• Speed classification: Standard Recovery >500ns, > 200mA (Io)

Mechanical & Environmental Equivalence Criteria:

• Package / Case: SOD-123F
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C
• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All substitute parts listed maintain these core parameters. Secondary parameters such as reverse recovery time (trr) and junction capacitance may vary within acceptable ranges for this product category and do not disqualify substitution eligibility.

Engineering Selection Recommendations

ACGRMS4007-HF (Primary Selection)

The ACGRMS4007-HF maintains Active product status with full AEC-Q101 automotive qualification and ROHS3 compliance. This part is recommended for new designs and ongoing production where Comchip Technology supply is available. Current inventory of 750 pieces supports immediate procurement.

S1MSWFQ-7 (Diodes Incorporated) - Preferred Substitute

The S1MSWFQ-7 is qualified as a direct substitute with Active product status. This part meets all electrical and mechanical equivalence criteria, including 1000 V reverse voltage, 1 A average rectified current, and SOD-123F surface mount packaging. AEC-Q101 qualification and ROHS3 compliance are maintained. Inventory availability of 1447 pieces supports supply chain flexibility. The reverse recovery time of 1 µs represents improved performance relative to the main part specification.

NRVS1MFL (onsemi) - Secondary Substitute

The NRVS1MFL meets all core electrical and mechanical equivalence parameters with AEC-Q101 qualification and ROHS3 compliance. However, this part carries Not For New Designs product status, indicating onsemi has discontinued active development. The NRVS1MFL is suitable only for legacy design support or replacement applications where existing designs already incorporate this component. Inventory of 7768 pieces is available. The reverse leakage current of 1 µA @ 1000 V represents improved performance relative to the main part specification.

Frequently Asked Questions (FAQ)

Q: Can S1MSWFQ-7 be used as a direct replacement for ACGRMS4007-HF in new designs?

A: Yes. The S1MSWFQ-7 meets all specified electrical parameters (1000 V reverse voltage, 1 A average rectified current, 1.1 V forward voltage @ 1 A), maintains identical SOD-123F surface mount packaging, and carries equivalent automotive-grade AEC-Q101 qualification with ROHS3 compliance. No circuit modifications are required.

Q: What is the difference between NRVS1MFL and the other substitutes?

A: The NRVS1MFL is electrically equivalent but carries Not For New Designs product status from onsemi. This designation indicates the manufacturer has transitioned away from active development and support. The part remains suitable for legacy applications and replacement scenarios but should not be selected for new design implementations.

Q: Are all substitute parts qualified for automotive applications?

A: Yes. All listed substitute parts carry automotive-grade classification with AEC-Q101 qualification, matching the main part ACGRMS4007-HF. All parts maintain operating temperature range of -55°C to 150°C junction temperature and ROHS3 compliance.

Q: Does the SOD-123F package remain identical across all parts?

A: Yes. The ACGRMS4007-HF, NRVS1MFL, and S1MSWFQ-7 all use SOD-123F surface mount packaging with identical mechanical footprint and mounting requirements. No PCB layout modifications are necessary when substituting between these parts.

Q: What is the significance of reverse recovery time (trr) differences?

A: Reverse recovery time is a secondary parameter not specified for the main part ACGRMS4007-HF. The S1MSWFQ-7 (1 µs trr) and NRVS1MFL (2 µs trr) both exceed the minimum standard recovery specification (>500ns, >200mA). These variations do not affect substitution eligibility for general-purpose rectification applications.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. All substitute parts share identical SOD-123F surface mount packaging, mechanical dimensions, and pin configuration. PCB footprints, solder reflow profiles, and assembly processes remain unchanged. No design or manufacturing modifications are required.
