SS12LHRUG Equivalent & Substitute Parts

Part Overview

The SS12LHRUG is a Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 20 V DC reverse voltage and 1 A average rectified current in a Sub SMA surface mount package. This component is classified as Active product status and meets automotive-grade specifications with AEC-Q101 qualification.

Equivalent and substitute parts are identified when alternative components satisfy the same electrical and mechanical requirements within the defined parameter tolerances. Substitutes become necessary due to inventory availability, supply chain considerations, or when the primary part reaches end-of-life status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SS12LHRUG is determined by equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

• Voltage - DC Reverse (Vr) (Max): 20 V
• Package / Case: DO-219AB
• Mounting Type: Surface Mount
• Technology: Schottky
• RoHS Status: ROHS3 Compliant

Allowable Variation Parameters:

• Current - Average Rectified (Io): Equal to or greater than 1 A
• Voltage - Forward (Vf) (Max) @ If: Equal to or less than 450 mV
• Current - Reverse Leakage @ Vr: Equal to or less than 400 µA @ 20 V
• Operating Temperature - Junction: Must include the range -55°C to 125°C

Substitute parts are classified as either parametric equivalents (identical electrical specifications) or similar parts (meeting or exceeding performance requirements within the same package and voltage class).

Parameter Comparison

Engineering Selection Recommendations

SS12L (Parametric Equivalent): The SS12L is a parametric equivalent to the SS12LHRUG, offering identical electrical specifications and package configuration. Both components are manufactured by Taiwan Semiconductor Corporation and comply with ROHS3 standards. However, the SS12L carries a product status designation of "Not For New Designs," indicating this part is in mature or declining production phase. Selection of SS12L is appropriate for legacy system maintenance, repair, or when existing design validation has been completed. For new product development, the SS12LHRUG (Active status) is the preferred choice.

SL02-GS08 (Similar - Vishay): The SL02-GS08 is a similar Schottky rectifier diode manufactured by Vishay General Semiconductor - Diodes Division, rated for 20 V DC reverse voltage with enhanced current capability (1.1 A versus 1 A). This part demonstrates superior electrical performance characteristics: lower forward voltage drop (420 mV @ 1.1 A versus 450 mV @ 1 A) and reduced reverse leakage current (250 µA @ 20 V versus 400 µA @ 20 V). The SL02-GS08 is housed in the identical DO-219AB package and maintains ROHS3 compliance with MSL 1 rating. The SL02-GS08 carries Active product status and is suitable for new designs. This part is a direct functional upgrade when higher current capacity or improved leakage characteristics are beneficial to circuit performance.

Both substitute parts maintain compatibility with the SS12LHRUG in terms of package footprint, mounting methodology, and thermal operating range. Selection between substitutes depends on design phase (new versus legacy), performance optimization objectives, and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can the SS12L be used as a direct replacement for the SS12LHRUG in new product designs?

A: The SS12L is electrically and mechanically equivalent to the SS12LHRUG. However, the SS12L carries a "Not For New Designs" product status designation. For new product development, the SS12LHRUG (Active status) is the recommended selection. The SS12L is appropriate for legacy system support and repair applications where design validation has already been completed.

Q: What are the key differences between the SS12LHRUG and the SL02-GS08?

A: Both parts share identical 20 V reverse voltage rating and DO-219AB package configuration. The SL02-GS08 offers enhanced performance: 1.1 A current rating (versus 1 A), lower forward voltage drop of 420 mV @ 1.1 A (versus 450 mV @ 1 A), and reduced reverse leakage current of 250 µA @ 20 V (versus 400 µA @ 20 V). The SL02-GS08 is manufactured by Vishay and carries Active product status. Both parts are ROHS3 compliant with MSL 1 rating.

Q: Are all three parts (SS12LHRUG, SS12L, SL02-GS08) compatible with the same PCB footprint?

A: Yes. All three parts utilize the DO-219AB package configuration with identical surface mount footprint dimensions. PCB layout and reflow soldering parameters remain unchanged across these three components.

Q: What is the operating temperature range for each substitute part?

A: The SS12LHRUG and SS12L both specify operating junction temperature range of -55°C to 125°C. The SL02-GS08 specifies a maximum junction temperature of 125°C. For applications requiring the full -55°C to 125°C range, the SS12LHRUG or SS12L are the appropriate selections.

Q: Which substitute part should be selected for improved circuit performance?

A: The SL02-GS08 provides superior electrical characteristics with lower forward voltage drop and reduced reverse leakage current. Selection of the SL02-GS08 is appropriate when circuit performance optimization is a design objective and the Vishay component is acceptable within the supply chain strategy.

Q: Are all three parts automotive-grade qualified?

A: The SS12LHRUG is explicitly designated as automotive-grade with AEC-Q101 qualification. The SS12L and SL02-GS08 specifications provided do not include explicit automotive-grade designation or AEC-Q101 qualification status. For automotive applications requiring AEC-Q101 compliance, the SS12LHRUG is the specified component.
