NRVRGF1M Equivalent & Substitute Parts

Part Overview

The NRVRGF1M is a general-purpose rectifier diode manufactured by onsemi, rated for 1000 V DC reverse voltage and 1 A average rectified current in a Surface Mount SMA package. This component is classified as "Not For New Designs," indicating it has been superseded in the manufacturer's product portfolio. Identifying equivalent and substitute parts is necessary for applications requiring continued support, legacy system maintenance, or when the primary part becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the NRVRGF1M are identified based on strict electrical and mechanical parameter compatibility. The primary substitution criteria are:

Critical Parameters for Substitution:

• Voltage - DC Reverse (Vr) (Max): 1000 V minimum
• Current - Average Rectified (Io): 1 A minimum
• Package / Case: DO-214AC (SMA) surface mount
• Reverse Recovery Time (trr): Fast recovery characteristic (≤ 500ns)
• Operating Temperature Range: Must encompass or exceed -65°C to 175°C

Parametric Equivalent Classification: Parts meeting all critical parameters with identical or superior electrical characteristics are classified as parametric equivalents. These parts perform the same function within the same electrical and thermal operating envelope.

Similar Manufacturer Part Classification: Parts that meet the core voltage and current requirements but may have variations in secondary parameters (such as technology type, reverse recovery time, or temperature range) are classified as similar parts. These require engineering evaluation for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

RGF1M (Parametric Equivalent - Recommended Primary Substitute)

The RGF1M is the recommended primary substitute for the NRVRGF1M. Both parts are manufactured by onsemi and share identical electrical specifications across all critical parameters: 1000 V reverse voltage, 1 A average rectified current, 1.3 V forward voltage drop, 500 ns reverse recovery time, and 5 µA reverse leakage current. The RGF1M maintains the same operating temperature range (-65°C to 175°C) and package configuration (DO-214AC, SMA). The primary difference is packaging format: NRVRGF1M is supplied in Tape & Reel (TR), while RGF1M is available in Cut Tape (CT) & Digi-Reel® format. Both parts carry ROHS3 compliance and MSL 1 rating. The RGF1M is suitable for direct replacement in applications where the NRVRGF1M is currently specified.

BYG21MHE3_A/H (Similar Part - Conditional Substitute)

The BYG21MHE3_A/H, manufactured by Vishay General Semiconductor - Diodes Division, is classified as a similar part due to differences in several parameters. This part maintains the 1000 V reverse voltage requirement and is housed in the same DO-214AC (SMA) package. However, it differs in the following aspects: higher current rating (1.5 A versus 1 A), higher forward voltage drop (1.6 V @ 1.5 A versus 1.3 V @ 1 A), faster reverse recovery time (120 ns versus 500 ns), lower reverse leakage current (1 µA versus 5 µA), and a narrower operating temperature range (-55°C to 150°C versus -65°C to 175°C). The BYG21MHE3_A/H uses avalanche technology rather than standard technology. Both parts are automotive-grade with AEC-Q101 qualification and ROHS3 compliance. The BYG21MHE3_A/H is suitable for applications where the higher current rating and faster recovery time provide system benefits, provided the operating temperature range is acceptable.

Frequently Asked Questions (FAQ)

Q: Can RGF1M be used as a direct replacement for NRVRGF1M?

A: Yes. The RGF1M is a parametric equivalent with identical electrical specifications. Both parts are manufactured by onsemi and share the same voltage rating (1000 V), current rating (1 A), forward voltage drop (1.3 V @ 1 A), reverse recovery time (500 ns), and operating temperature range (-65°C to 175°C). The only difference is the packaging format (Tape & Reel versus Cut Tape & Digi-Reel®). Direct substitution is appropriate for applications currently using NRVRGF1M.

Q: What are the key differences between NRVRGF1M and BYG21MHE3_A/H?

A: The primary differences are: (1) Current rating: BYG21MHE3_A/H is rated for 1.5 A versus 1 A for NRVRGF1M; (2) Forward voltage drop: 1.6 V @ 1.5 A for BYG21MHE3_A/H versus 1.3 V @ 1 A for NRVRGF1M; (3) Reverse recovery time: 120 ns for BYG21MHE3_A/H versus 500 ns for NRVRGF1M; (4) Reverse leakage current: 1 µA for BYG21MHE3_A/H versus 5 µA for NRVRGF1M; (5) Operating temperature range: -55°C to 150°C for BYG21MHE3_A/H versus -65°C to 175°C for NRVRGF1M; (6) Technology: Avalanche for BYG21MHE3_A/H versus Standard for NRVRGF1M. Both parts share the same 1000 V reverse voltage rating and DO-214AC (SMA) package.

Q: Are all substitute parts automotive-qualified?

A: NRVRGF1M and BYG21MHE3_A/H are both automotive-grade with AEC-Q101 qualification. RGF1M does not specify automotive grade or AEC-Q101 qualification in the provided data. Applications requiring automotive qualification should prioritize NRVRGF1M or BYG21MHE3_A/H.

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

A: Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® are different packaging and delivery formats for surface mount components. Both formats contain the same component in the same DO-214AC (SMA) package. The difference lies in how the components are supplied: TR provides components on a continuous reel, while CT & Digi-Reel® provides components on cut tape segments or alternative reel formats. Selection between these formats depends on assembly equipment compatibility and procurement requirements.

Q: Can BYG21MHE3_A/H be used in applications with operating temperatures below -55°C?

A: No. The BYG21MHE3_A/H has a minimum operating temperature of -55°C, whereas NRVRGF1M operates down to -65°C. Applications requiring operation at temperatures below -55°C must use NRVRGF1M or RGF1M, both of which support the full -65°C to 175°C range.

Q: What does "Not For New Designs" status mean for NRVRGF1M?

A: "Not For New Designs" indicates that onsemi has superseded this part in their product portfolio. While the part remains available and functional, it is not recommended for new product development. For new designs, RGF1M (parametric equivalent) or BYG21MHE3_A/H (similar part) should be considered as forward-compatible alternatives.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. NRVRGF1M, RGF1M, and BYG21MHE3_A/H are all ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. All parts are also REACH Unaffected and classified under ECCN EAR99.
