RS2A-13 Equivalent & Substitute Parts

Part Overview

The RS2A-13 is a general-purpose rectifier diode manufactured by Diodes Incorporated, rated for 50 V DC reverse voltage and 1.5 A average rectified current in a Surface Mount SMB (DO-214AA) package. This component is classified as a fast recovery diode with a reverse recovery time of 150 ns, suitable for standard rectification applications requiring moderate current handling and voltage ratings.

The RS2A-13 is currently discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications. Substitute parts must maintain electrical performance characteristics while accommodating packaging and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RS2A-13 are identified based on matching the following critical electrical and mechanical parameters:

Electrical Matching Criteria:

• Voltage - DC Reverse (Vr) (Max): 50 V
• Current - Average Rectified (Io): 1.5 A
• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 1.5 A
• Reverse Recovery Time (trr): 150 ns
• Current - Reverse Leakage @ Vr: 5 µA @ 50 V
• Capacitance @ Vr, F: 30 pF @ 4V, 1MHz
• Operating Temperature - Junction: -65°C to 150°C
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Matching Criteria:

• Mounting Type: Surface Mount
• Base Product Number: RS2A

The RS2A-13-F is identified as a direct substitute based on identical electrical performance specifications. The primary difference is packaging format and product status, with the substitute available in active production status.

Parameter Comparison

Engineering Selection Recommendations

The RS2A-13-F is a direct electrical equivalent to the RS2A-13, with all critical electrical parameters matching exactly. Selection between these parts is determined by application requirements and compliance mandates:

For applications requiring RoHS3 compliance: The RS2A-13-F is the appropriate selection, as it meets ROHS3 compliance requirements while the RS2A-13 is RoHS non-compliant.

For applications with no RoHS compliance requirement: Either part is electrically suitable; however, the RS2A-13-F is recommended due to active product status and higher inventory availability.

Package and mounting considerations: The RS2A-13 uses DO-214AA (SMB) package format, while the RS2A-13-F uses DO-214AC (SMA) package format. PCB layout and footprint compatibility must be verified before substitution. Both are surface mount packages with different physical dimensions.

Tape & Reel packaging: The RS2A-13-F is supplied in Tape & Reel format, suitable for automated assembly processes. The RS2A-13 is supplied in bulk packaging.

Both parts share identical REACH and ECCN classifications (REACH Unaffected, EAR99) and Moisture Sensitivity Level (MSL 1 - Unlimited).

Frequently Asked Questions (FAQ)

Q: Can the RS2A-13-F be used as a direct replacement for the RS2A-13 in existing designs?

A: The RS2A-13-F is electrically equivalent to the RS2A-13 with identical voltage, current, and switching characteristics. However, the package format differs (DO-214AC SMA versus DO-214AA SMB). PCB footprint compatibility must be verified before substitution. If the PCB footprint accommodates the SMA package, electrical substitution is valid.

Q: What is the difference between SMB and SMA packages?

A: SMB (DO-214AA) and SMA (DO-214AC) are both surface mount diode packages but have different physical dimensions and footprints. The SMA package is typically smaller. Substitution requires PCB layout verification to ensure the component footprint matches the available pad pattern.

Q: Why is the RS2A-13 discontinued?

A: The RS2A-13 is discontinued at DiGi Electronics. The RS2A-13-F remains in active production and is the recommended source for new component procurement.

Q: Are there compliance differences between the RS2A-13 and RS2A-13-F?

A: Yes. The RS2A-13-F is ROHS3 compliant, while the RS2A-13 is RoHS non-compliant. Both are REACH Unaffected. For applications subject to RoHS3 requirements, the RS2A-13-F is the required selection.

Q: Do the electrical characteristics differ between these parts?

A: No. Both parts have identical electrical specifications: 50 V reverse voltage, 1.5 A average rectified current, 1.3 V forward voltage drop at 1.5 A, 150 ns reverse recovery time, and identical leakage and capacitance characteristics.

Q: What is the operating temperature range for both parts?

A: Both the RS2A-13 and RS2A-13-F operate across a junction temperature range of -65°C to 150°C.

Q: Is the RS2A-13-F available in higher quantities?

A: Yes. The RS2A-13-F has 6300 pieces in stock compared to 1051 pieces for the RS2A-13, providing greater availability for production requirements.

Q: What packaging format is the RS2A-13-F supplied in?

A: The RS2A-13-F is supplied in Tape & Reel (TR) format, suitable for automated pick-and-place assembly. The RS2A-13 is supplied in bulk packaging.
