SS115LHRHG Equivalent & Substitute Parts

Part Overview

The SS115LHRHG is a Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, designed for surface mount applications in the Sub SMA package format. This component operates at 150 V DC reverse voltage with 1 A average rectified current and is qualified to AEC-Q101 automotive standards. The part is currently in active production status with 720 pieces available in inventory.

Identification of equivalent and substitute parts becomes necessary when the primary part number reaches end-of-life status, when inventory constraints occur, or when design flexibility is required across manufacturing locations. The SS115LHRHG has documented substitutes within the same product family that maintain electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the SS115LHRHG is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 150 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 900 mV @ 1 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 50 µA @ 150 V
• Operating Temperature - Junction: -55°C to 150°C

Mechanical Parameters (Must Match):

• Package / Case: DO-219AB
• Mounting Type: Surface Mount
• Supplier Device Package: Sub SMA

Compliance Parameters (Must Match):

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

The SS115L is identified as a parametric equivalent substitute. This part maintains identical electrical specifications and mechanical compatibility while differing in product status and packaging format (Tape & Reel versus bulk packaging).

Parameter Comparison

Engineering Selection Recommendations

For Active Production Applications: The SS115LHRHG is the preferred selection for new designs and active production due to its Active product status. This part carries full manufacturer support and is recommended for designs requiring long-term availability and supply chain stability.

For Existing Designs or Inventory Constraints: The SS115L serves as a direct electrical and mechanical substitute when the SS115LHRHG is unavailable. The SS115L maintains all critical electrical parameters and package specifications. However, the SS115L carries a "Not For New Designs" status, indicating it is in a mature or transitional phase of its product lifecycle. Selection of SS115L should be limited to applications where existing designs require component replacement or where inventory availability of the primary part is constrained.

Packaging Consideration: The SS115L is supplied in Tape & Reel (TR) format, which differs from the bulk packaging of the SS115LHRHG. This distinction affects procurement quantities and handling procedures but does not impact electrical or mechanical compatibility.

Compliance Verification: Both parts maintain ROHS3 compliance and AEC-Q101 automotive qualification, ensuring suitability for regulated applications and automotive-grade circuit designs.

Frequently Asked Questions (FAQ)

Q: Can SS115L be used as a direct replacement for SS115LHRHG in existing circuit designs?

A: Yes. The SS115L maintains identical electrical specifications across all critical parameters: 150 V reverse voltage, 1 A average rectified current, 900 mV forward voltage drop at 1 A, and fast recovery characteristics. Both parts use the DO-219AB package in Sub SMA format with surface mount compatibility. No circuit redesign is required.

Q: What is the difference between SS115LHRHG and SS115L?

A: The primary differences are product status and packaging format. SS115LHRHG is in Active status with bulk packaging, while SS115L is marked "Not For New Designs" and supplied in Tape & Reel format. All electrical and mechanical specifications are identical.

Q: Why is SS115L marked "Not For New Designs"?

A: This designation indicates the part is in a mature phase of its lifecycle. Manufacturers apply this status to parts that remain available for existing applications but are not recommended for incorporation into new product designs. For new designs, SS115LHRHG is the appropriate selection.

Q: Are there any temperature or voltage derating considerations when substituting SS115L for SS115LHRHG?

A: No. Both parts operate across the identical temperature range (-55°C to 150°C junction temperature) and voltage specifications (150 V maximum reverse voltage). No derating adjustments are necessary.

Q: Does the Tape & Reel packaging of SS115L affect electrical performance?

A: No. Tape & Reel is a packaging and delivery format only. It does not alter the electrical characteristics, performance, or reliability of the diode itself. The component specifications remain identical regardless of packaging format.

Q: Are both parts suitable for automotive applications?

A: Yes. Both SS115LHRHG and SS115L carry AEC-Q101 automotive qualification and are graded for automotive use. Both maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: What is the reverse leakage current specification for these parts?

A: Both parts specify 50 µA maximum reverse leakage current at 150 V. This parameter is identical across both the main part and substitute.
