FR2A Equivalent & Substitute Parts

Part Overview

The FR2A is a general-purpose rectifier diode manufactured by SMC Diode Solutions, rated for 50 V DC reverse voltage and 2 A average rectified current in a surface mount SMB (DO-214AA) package. This diode is classified as a fast recovery device with a reverse recovery time of 150 ns, suitable for standard rectification applications requiring moderate current handling and voltage blocking capability. The part is currently in active production status with 4300 units in stock. Equivalent and substitute parts are identified to provide design flexibility, supply chain alternatives, and component availability options for applications where the FR2A specifications are met by alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FR2A are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters:

Electrical Specifications:

• Voltage - DC Reverse (Vr) (Max): 50 V
• Current - Average Rectified (Io): 2 A
• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 2 A
• Reverse Recovery Time (trr): 150 ns
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical & Package Specifications:

• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -50°C to 150°C

Compliance & Regulatory:

• RoHS Status: ROHS3 Compliant
• Packaging: Tape & Reel (TR)

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. Secondary parameters such as reverse leakage current and junction capacitance may vary within acceptable ranges without affecting primary circuit function.

Parameter Comparison

Engineering Selection Recommendations

Both the FR2A (SMC Diode Solutions) and FR2A_R1_00001 (Panjit International Inc.) are active production parts with ROHS3 compliance and identical primary electrical and mechanical specifications. Selection between these parts should be based on the following factors:

Primary Selection Criteria:

1. Supply Chain Availability: The FR2A maintains 4300 units in stock, while FR2A_R1_00001 has 1582 units available. For high-volume or time-critical applications, the FR2A offers greater inventory depth.

2. Regulatory Compliance: Both parts are ROHS3 compliant. The FR2A is REACH Affected, while FR2A_R1_00001 is REACH Unaffected. Applications subject to REACH restrictions should specify FR2A_R1_00001.

3. Secondary Performance Characteristics: FR2A_R1_00001 demonstrates lower reverse leakage current (1 µA versus 5 µA @ 50 V) and lower junction capacitance (40 pF versus 50 pF @ 4V, 1MHz). These characteristics may provide marginal benefits in low-leakage or high-frequency switching applications, though both parts meet the primary 50 V, 2 A, 150 ns specification.

4. Packaging and Handling: Both parts are supplied in Tape & Reel (TR) packaging with MSL 1 (Unlimited) moisture sensitivity, ensuring identical handling and storage requirements.

Either part is suitable for direct substitution in applications designed for the FR2A specification. No circuit redesign or re-qualification is required when switching between these parts.

Frequently Asked Questions (FAQ)

Q: Can FR2A_R1_00001 be used as a direct replacement for FR2A in existing designs?

A: Yes. FR2A_R1_00001 meets all primary electrical specifications (50 V, 2 A, 1.3 V forward drop, 150 ns recovery time) and mechanical requirements (DO-214AA SMB package, surface mount, -50°C to 150°C operating range). No circuit modification is required.

Q: What is the difference between the two parts?

A: The primary differences are manufacturer (SMC Diode Solutions versus Panjit International Inc.), inventory availability (4300 versus 1582 units), and secondary electrical characteristics. FR2A_R1_00001 has lower reverse leakage current (1 µA versus 5 µA) and lower junction capacitance (40 pF versus 50 pF). Both parts are ROHS3 compliant, but FR2A is REACH Affected while FR2A_R1_00001 is REACH Unaffected.

Q: Are the packages identical?

A: Yes. Both parts use the DO-214AA SMB surface mount package with identical pin configuration, footprint, and soldering requirements. Both are supplied in Tape & Reel (TR) packaging with MSL 1 (Unlimited) moisture sensitivity.

Q: Which part should I select for a new design?

A: Selection depends on supply chain strategy and regulatory requirements. For maximum inventory availability, specify FR2A. For REACH-unrestricted applications or designs benefiting from lower leakage current, specify FR2A_R1_00001. Both parts are active production items suitable for new designs.

Q: Do these parts have the same operating temperature range?

A: Yes. Both parts operate across the junction temperature range of -50°C to 150°C, ensuring identical thermal performance and reliability characteristics.

Q: Can I mix these parts in the same production batch?

A: Yes. Since both parts are parametric equivalents with identical primary specifications, they can be used interchangeably within the same circuit design and production batch without affecting circuit performance or reliability.

Q: What is the significance of the reverse recovery time specification?

A: The 150 ns reverse recovery time classifies both parts as fast recovery diodes, suitable for switching applications requiring rapid diode turn-off. This specification is identical between FR2A and FR2A_R1_00001.
