SS310 R6 Equivalent & Substitute Parts

Part Overview

The SS310 R6 is a Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 100 V DC reverse voltage and 3 A average rectified current in a DO-214AB surface mount package. This component is classified as discontinued at DiGi Electronics, necessitating identification of equivalent alternatives for ongoing production and repair applications. Substitute parts must maintain identical electrical performance characteristics and package compatibility to ensure direct replacement capability in existing circuit designs.

Substitute Part Grouping Explanation

Substitute parts for the SS310 R6 are qualified based on the following critical parameters:

Electrical Equivalence Criteria:

Voltage - DC Reverse (Vr) (Max): 100 V
Current - Average Rectified (Io): 3 A
Voltage - Forward (Vf) (Max) @ If: 850 mV @ 3 A
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
Current - Reverse Leakage @ Vr: 100 µA @ 100 V
Operating Temperature - Junction: -55°C to 150°C

Mechanical Equivalence Criteria:

Package / Case: DO-214AB, SMC
Mounting Type: Surface Mount

Compliance Equivalence Criteria:

RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level (MSL): 1 (Unlimited)

All identified substitute parts meet these criteria and are therefore suitable for direct replacement in applications requiring the SS310 R6 electrical and mechanical specifications.

Engineering Selection Recommendations

SS310H (Taiwan Semiconductor Corporation)

The SS310H is an active product offering identical electrical and mechanical specifications to the SS310 R6. This part carries automotive-grade qualification (AEC-Q101) and is supplied in Tape & Reel packaging. With 3715 units in stock, this represents the primary substitute option for the discontinued SS310 R6. Both parts are manufactured by Taiwan Semiconductor Corporation and maintain full ROHS3 compliance and MSL 1 rating.

SK310HE3-TP (Micro Commercial Co)

The SK310HE3-TP is an active product from an alternative manufacturer meeting all electrical and mechanical requirements of the SS310 R6. This part also carries automotive-grade qualification (AEC-Q101) and includes specified capacitance data (250 pF @ 4V, 1MHz). Supplied in Tape & Reel packaging with 3588 units in stock, this part provides a cross-manufacturer alternative while maintaining full ROHS3 compliance and MSL 1 rating.

Both substitute parts are suitable for direct replacement based on product status, compliance certifications, and parametric equivalence.

Frequently Asked Questions (FAQ)

Q: Can the SS310H directly replace the SS310 R6 in existing designs?

A: Yes. The SS310H meets all electrical parameters (100 V reverse voltage, 3 A current rating, 850 mV forward voltage, fast recovery speed characteristics) and is packaged in the identical DO-214AB surface mount case. Both parts are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between the SS310H and SK310HE3-TP?

A: Both parts are electrically and mechanically equivalent to the SS310 R6. The primary differences are manufacturer (Taiwan Semiconductor Corporation versus Micro Commercial Co) and packaging format (both supplied in Tape & Reel). The SK310HE3-TP includes specified capacitance data (250 pF @ 4V, 1MHz), while this parameter is not specified for the SS310H.

Q: Are both substitute parts automotive qualified?

A: Yes. Both the SS310H and SK310HE3-TP carry AEC-Q101 automotive qualification, making them suitable for automotive and industrial applications requiring this certification level.

Q: Does the DO-214AB package ensure mechanical compatibility?

A: Yes. All three parts (SS310 R6, SS310H, and SK310HE3-TP) use the DO-214AB surface mount package (SMC), ensuring identical PCB footprint and mounting compatibility.

Q: What is the inventory status of substitute parts?

A: The SS310H has 3715 units in stock, and the SK310HE3-TP has 3588 units in stock. Both are classified as active products with ongoing availability.

Q: Are there any compliance differences between the main part and substitutes?

A: No. All three parts maintain identical RoHS3 compliance status, MSL 1 rating, REACH unaffected status, and ECCN/HTSUS classifications.
