SS115LHMQG Equivalent & Substitute Parts

Part Overview

The SS115LHMQG 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 851 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. Substitute parts must maintain identical electrical performance and mechanical compatibility to ensure direct replacement without circuit redesign.

Substitute Part Grouping Explanation

Substitution of the SS115LHMQG is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

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

Mechanical Parameters (Must Match Exactly):

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

Environmental & Compliance Parameters (Must Match Exactly):

• Operating Temperature - Junction: -55°C to 150°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

The substitute part SS115L meets all electrical, mechanical, and environmental requirements for direct substitution. Packaging format differences (Tape & Reel versus standard packaging) do not affect electrical or mechanical compatibility and represent only a supply chain variation.

Parameter Comparison

Engineering Selection Recommendations

SS115L as Direct Substitute:

The SS115L is a parametric equivalent to the SS115LHMQG and provides complete electrical and mechanical interchangeability. All critical performance parameters—reverse voltage, forward current, forward voltage drop, recovery speed, and leakage current—are identical. Both parts share the same DO-219AB package, Sub SMA supplier device package, and surface mount mounting type.

The SS115L carries a "Not For New Designs" product status designation. This status indicates the part remains available for existing production and support applications but is not recommended for new circuit designs. For applications currently using SS115LHMQG, the SS115L serves as a valid substitute when inventory or supply chain requirements necessitate an alternative source.

Both parts maintain identical compliance certifications: ROHS3 compliance, REACH unaffected status, and AEC-Q101 automotive qualification (where applicable). Moisture sensitivity level 1 (unlimited) indicates no special handling requirements for either part.

The packaging format difference (Tape & Reel for SS115L versus standard packaging for SS115LHMQG) represents a supply chain variation only and does not affect electrical performance or mechanical fit on printed circuit boards.

Frequently Asked Questions (FAQ)

Q: Can SS115L replace SS115LHMQG in existing designs?

A: Yes. The SS115L provides complete electrical and mechanical equivalence to the SS115LHMQG. All electrical parameters, package dimensions, and mounting characteristics are identical. The parts are directly interchangeable at the component level.

Q: What does "Not For New Designs" mean for the SS115L?

A: This product status indicates that while SS115L remains available for production and support of existing applications, Taiwan Semiconductor Corporation does not recommend this part number for new circuit designs. For new designs, the SS115LHMQG (active status) is the preferred selection. However, for existing production lines or replacement inventory, SS115L is a valid substitute.

Q: Are there any differences in electrical performance between SS115LHMQG and SS115L?

A: No. Both parts have identical electrical specifications: 150 V reverse voltage, 1 A average rectified current, 900 mV forward voltage drop at 1 A, fast recovery speed (≤ 500ns), and 50 µA reverse leakage current at 150 V.

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

A: No. Tape & Reel is a supply format variation used for automated assembly processes. The individual component—the diode itself—is identical to the standard packaging format. Once removed from the tape, the SS115L diode is mechanically and electrically identical to SS115LHMQG.

Q: Are both parts qualified to the same automotive standards?

A: Yes. Both SS115LHMQG and SS115L carry AEC-Q101 automotive qualification and ROHS3 compliance. They meet identical environmental and regulatory requirements.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life and no special moisture control requirements during storage or handling.

Q: Can I use SS115L in a new design instead of SS115LHMQG?

A: While SS115L is electrically and mechanically equivalent, Taiwan Semiconductor Corporation designates it as "Not For New Designs." For new circuit designs, use SS115LHMQG (active status). The SS115L is appropriate for production support and replacement inventory of existing applications.
