SS310LHRVG Equivalent & Substitute Parts

Part Overview

The SS310LHRVG 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 Sub SMA surface mount package. This component is classified as Active product status and carries AEC-Q101 automotive qualification.

Equivalent and substitute parts are necessary when the primary part number becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design flexibility permits selection from qualified alternatives that meet identical electrical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the SS310LHRVG is determined by the following critical parameters:

Mandatory Matching Parameters:

Voltage - DC Reverse (Vr) (Max): 100 V
Package / Case: DO-219AB
Mounting Type: Surface Mount
Technology: Schottky
Fast Recovery characteristic: ≤ 500ns, > 200mA (Io)

Current Rating Consideration: The SS310LHRVG is rated for 3 A average rectified current. Substitute parts with lower current ratings (1 A or 2 A) are classified as similar parts rather than direct parametric equivalents, as they cannot support the full 3 A specification. These parts are suitable only when circuit design permits operation at reduced current levels.

Packaging Format Variations: Substitute parts may differ in packaging format (Tape & Reel, Cut Tape, Digi-Reel) without affecting electrical compatibility, as these represent manufacturing and supply chain variations of the same component package.

Product Status: The SS310L is a parametric equivalent with identical electrical specifications but carries "Not For New Designs" status. This part remains functionally equivalent for existing designs and maintenance applications.

Engineering Selection Recommendations

Parametric Equivalent:

SS310L is the direct parametric equivalent to SS310LHRVG, matching all electrical specifications including 100 V reverse voltage, 3 A current rating, and 850 mV forward voltage. Both parts are housed in DO-219AB packages with identical thermal and electrical characteristics. SS310L carries "Not For New Designs" status, indicating it is suitable for replacement in existing designs and field maintenance applications but should not be selected for new product development.

Similar Parts with Reduced Current Ratings:

SS1FH10-M3/H, SS1FH10HM3/H, SS2FH10-M3/H, and SS2FH10HM3/H are Vishay General Semiconductor alternatives with identical 100 V reverse voltage and DO-219AB packaging. These parts are classified as similar rather than equivalent due to lower current ratings (1 A and 2 A respectively). Selection of these parts is limited to applications where circuit design permits operation below the 3 A specification of the main part.

SS1FH10HM3/H and SS2FH10HM3/H carry AEC-Q101 automotive qualification matching the main part's certification status. Both Vishay parts feature extended operating temperature range (-55°C to 175°C) compared to the main part (-55°C to 150°C).

Compliance and Certification:

All listed parts maintain ROHS3 compliance and REACH unaffected status. Selection should prioritize parts with matching AEC-Q101 qualification for automotive applications.

Frequently Asked Questions (FAQ)

Q: Can SS310L be used as a direct replacement for SS310LHRVG?

A: Yes. SS310L is a parametric equivalent with identical electrical specifications: 100 V reverse voltage, 3 A average rectified current, 850 mV forward voltage, and DO-219AB package. The primary difference is product status designation. SS310L is suitable for replacement in existing designs and maintenance applications.

Q: What is the difference between SS310LHRVG and the Vishay SS1FH10 and SS2FH10 series?

A: The Vishay parts differ in current rating. SS1FH10 series is rated for 1 A, and SS2FH10 series is rated for 2 A, compared to 3 A for the SS310LHRVG. All share identical 100 V reverse voltage and DO-219AB packaging. Vishay parts are suitable only when circuit design permits operation at reduced current levels.

Q: Are packaging format variations (Tape & Reel, Cut Tape, Digi-Reel) electrically equivalent?

A: Yes. Packaging format variations represent supply chain and manufacturing process differences only. Electrical and thermal characteristics remain identical across all packaging formats for the same part number base.

Q: Does the extended temperature range of Vishay parts (-55°C to 175°C) affect compatibility?

A: Extended temperature range does not affect compatibility. The SS310LHRVG operates within -55°C to 150°C. Vishay parts with -55°C to 175°C range are compatible and provide additional thermal margin for applications requiring higher temperature operation.

Q: Which substitute parts carry AEC-Q101 automotive qualification?

A: SS310L (parametric equivalent), SS1FH10HM3/H (1 A Vishay), and SS2FH10HM3/H (2 A Vishay) carry AEC-Q101 qualification. For automotive applications, these parts are preferred over non-qualified alternatives.

Q: Can lower-rated Vishay parts (1 A or 2 A) be used in applications designed for 3 A?

A: No. Lower-rated parts cannot support the full 3 A specification. These parts are suitable only when circuit design permits operation at their respective current ratings (1 A or 2 A maximum).

Q: What is the significance of "Not For New Designs" status on SS310L?

A: This designation indicates the part is suitable for replacement and maintenance of existing designs but should not be selected for new product development. For new designs, SS310LHRVG (Active status) is the preferred selection.
