NRVRGF1B Equivalent & Substitute Parts

Part Overview

The NRVRGF1B is a general-purpose rectifier diode manufactured by onsemi, rated for 100 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 reached end-of-life status. Applications requiring this diode specification must transition to active alternative components that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the NRVRGF1B are selected based on strict electrical and mechanical parameter matching within the rectifier diode category. The substitution logic is based on the following criteria:

Primary Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 100 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 1 A
• Reverse Recovery Time (trr): 150 ns
• Current - Reverse Leakage @ Vr: 5 µA @ 100 V
• Package / Case: DO-214AC, SMA
• Mounting Type: Surface Mount
• Technology: Standard
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Substitute Classification:

Parametric Equivalent: RGF1B (Fairchild Semiconductor) — Identical electrical specifications and package configuration. Differs in product status (Active vs. Not For New Designs) and packaging format (Bulk vs. Tape & Reel).

Similar Equivalent: RS1BHE3_A/H (Vishay General Semiconductor - Diodes Division) — Meets all primary electrical parameters with minor variations in capacitance (10 pF vs. 8.5 pF @ 4V, 1MHz) and operating temperature range (-55°C to 150°C vs. -65°C to 175°C). Includes automotive-grade qualification (AEC-Q101) and RoHS3 compliance matching the main part.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalent):

RGF1B from Fairchild Semiconductor provides identical electrical performance and package compatibility. This part is actively manufactured and suitable for new designs. Selection of RGF1B is appropriate when bulk packaging is acceptable and automotive qualification is not required.

For Automotive and Compliance-Critical Applications:

RS1BHE3_A/H from Vishay General Semiconductor maintains automotive-grade designation and AEC-Q101 qualification, matching the compliance profile of the original NRVRGF1B. This part is actively manufactured and recommended for applications requiring sustained automotive qualification and RoHS3 compliance verification. The operating temperature range (-55°C to 150°C) is narrower than the original part; applications requiring the full -65°C to 175°C range must confirm compatibility with specific circuit requirements.

Product Status Consideration:

The NRVRGF1B is classified as "Not For New Designs." Both substitute parts carry Active product status, making them suitable for new circuit development and long-term supply chain planning.

Frequently Asked Questions (FAQ)

Q: Can RGF1B be used as a direct drop-in replacement for NRVRGF1B?

A: Yes. RGF1B matches all primary electrical parameters (100 V reverse voltage, 1 A average rectified current, 1.3 V forward voltage, 150 ns reverse recovery time) and uses the identical DO-214AC (SMA) surface mount package. Physical and electrical compatibility is confirmed.

Q: What is the difference between RGF1B and RS1BHE3_A/H?

A: Both parts meet the core electrical specifications. RS1BHE3_A/H includes automotive-grade qualification (AEC-Q101) and maintains the automotive designation of the original NRVRGF1B. RGF1B does not specify automotive qualification. The operating temperature range of RS1BHE3_A/H (-55°C to 150°C) is narrower than both NRVRGF1B and RGF1B (-65°C to 175°C). Capacitance differs slightly: RS1BHE3_A/H is rated at 10 pF versus 8.5 pF for the other parts.

Q: Which substitute is recommended for automotive applications?

A: RS1BHE3_A/H is recommended for automotive applications due to its AEC-Q101 qualification and automotive-grade designation, matching the compliance requirements of the original NRVRGF1B.

Q: Does the capacitance difference between RGF1B/NRVRGF1B (8.5 pF) and RS1BHE3_A/H (10 pF) affect circuit performance?

A: The capacitance difference of 1.5 pF is measured at 4 V and 1 MHz. Circuit impact depends on specific application requirements. Applications sensitive to junction capacitance effects must evaluate this parameter against circuit design specifications.

Q: Are both substitute parts available in the same packaging formats as NRVRGF1B?

A: NRVRGF1B is supplied in Tape & Reel (TR) packaging. RGF1B is supplied in Bulk packaging. RS1BHE3_A/H is supplied in Tape & Reel (TR) packaging, matching the original packaging format. Packaging format selection depends on assembly process requirements and inventory management practices.

Q: What is the significance of the "Not For New Designs" status of NRVRGF1B?

A: This status indicates the part has reached end-of-life and is no longer recommended for new circuit development. Both substitute parts carry Active status, confirming their suitability for new designs and long-term availability.

Q: Are both substitute parts RoHS3 compliant?

A: RoHS3 compliance is confirmed for NRVRGF1B and RS1BHE3_A/H. RoHS status is not specified in the available data for RGF1B. Applications requiring verified RoHS3 compliance should confirm this requirement with the supplier for RGF1B.
