Substitute Part Grouping Explanation

Substitute parts for the MBRD320RL are classified based on electrical and mechanical parameter equivalence. All substitute candidates maintain identical specifications across the following critical parameters:

• Voltage - DC Reverse (Vr) (Max): 20 V
• Current - Average Rectified (Io): 3 A
• Voltage - Forward (Vf) (Max) @ If: 600 mV @ 3 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 200 µA @ 20 V
• Package / Case: TO-252-3, DPAK (2 Leads + Tab), SC-63
• Mounting Type: Surface Mount
• Technology: Schottky

Parametric equivalents (MBRD320RLG and MBRD320T4G) are direct onsemi alternatives with identical electrical performance and package specifications. The similar part (VS-MBRD320-M3) is a Vishay General Semiconductor equivalent that meets all electrical and mechanical requirements while offering active product status.

Parameter Comparison

Engineering Selection Recommendations

MBRD320RLG and MBRD320T4G are parametric equivalents from onsemi with identical electrical and mechanical specifications to the MBRD320RL. Both parts are ROHS3 compliant, addressing regulatory requirements where the original part does not. MBRD320T4G offers higher inventory availability (19,320 pcs) compared to MBRD320RLG (5,154 pcs).

VS-MBRD320-M3 is a Vishay General Semiconductor equivalent that meets all electrical and mechanical requirements. This part carries active product status, ensuring long-term availability and supply chain continuity. The operating temperature range is -40°C to 150°C, which is narrower than the MBRD320RL (-65°C to 150°C) and should be evaluated for applications requiring extended low-temperature operation below -40°C. VS-MBRD320-M3 is ROHS3 compliant and offers the highest inventory level (30,300 pcs).

All substitute parts maintain identical voltage ratings, current ratings, forward voltage characteristics, switching speed, and reverse leakage specifications. Package and mounting type are identical across all options, ensuring direct mechanical and electrical compatibility in existing PCB designs.

Frequently Asked Questions (FAQ)

Q: Can MBRD320RLG be used as a direct replacement for MBRD320RL?

A: Yes. MBRD320RLG is a parametric equivalent with identical electrical specifications (20 V, 3 A, 600 mV forward voltage, fast recovery ≤ 500ns) and identical DPAK package configuration. Both are onsemi products with the same base product number (MBRD320).

Q: What is the difference between MBRD320T4G and MBRD320RLG?

A: Both parts are onsemi parametric equivalents with identical electrical and mechanical specifications. The primary difference is packaging format: MBRD320T4G is supplied in Cut Tape (CT) while MBRD320RLG is supplied in standard packaging. MBRD320T4G has higher inventory availability.

Q: Is VS-MBRD320-M3 compatible with the MBRD320RL?

A: Yes. VS-MBRD320-M3 is a Vishay equivalent that meets all electrical parameters (20 V, 3 A, 600 mV forward voltage, fast recovery ≤ 500ns) and uses the identical TO-252-3 DPAK package. The operating temperature range is -40°C to 150°C, which is narrower than the MBRD320RL. Applications requiring operation below -40°C should not use this substitute.

Q: Why is the MBRD320RL marked as obsolete?

A: The MBRD320RL is classified as obsolete product status. Equivalent and substitute parts are available from both onsemi and Vishay to support continued system requirements and procurement needs.

Q: Are all substitute parts RoHS compliant?

A: MBRD320RLG, MBRD320T4G, and VS-MBRD320-M3 are all ROHS3 compliant. The original MBRD320RL is RoHS non-compliant. Regulatory requirements may necessitate substitution with compliant alternatives.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. All substitute parts use the identical TO-252-3 DPAK (2 Leads + Tab) package with SC-63 designation. Pin configuration and footprint are identical, enabling direct PCB-level substitution without design modification.

Q: Which substitute part offers the best long-term availability?

A: VS-MBRD320-M3 carries active product status, indicating ongoing production and long-term availability. MBRD320RLG and MBRD320T4G are both obsolete. For new designs or long-term procurement planning, VS-MBRD320-M3 is the recommended choice.

Q: What is the capacitance specification for these parts?

A: The MBRD320RL and MBRD320RLG do not specify capacitance. VS-MBRD320-M3 specifies 189 pF @ 5 V, 1 MHz. MBRD320T4G does not specify capacitance. Capacitance is not a determining factor for substitution compatibility.
