SS115LHM2G Equivalent & Substitute Parts

Part Overview

The SS115LHM2G 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 capability and is qualified to AEC-Q101 automotive standards. The part is currently in Active product status with 860 pieces available in new original inventory.

Substitute parts become necessary when the primary part number reaches end-of-life status, inventory constraints occur, or when design flexibility is required across manufacturing locations. The SS115LHM2G has identified parametric equivalents that maintain identical electrical and mechanical specifications while offering alternative packaging or availability options.

Substitute Part Grouping Explanation

Substitution of the SS115LHM2G is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part SS115L maintains identical performance specifications:

Substitution Criteria (All 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
• Package / Case: DO-219AB
• Mounting Type: Surface Mount
• Technology: Schottky
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The primary difference between the main part and its substitute lies in product status and packaging format. The SS115LHM2G is designated for Active designs, while SS115L carries a Not For New Designs status. Packaging differs in that SS115L is supplied in Tape & Reel (TR) format, whereas SS115LHM2G uses standard packaging.

Parameter Comparison

Engineering Selection Recommendations

For Active Design Programs: The SS115LHM2G is the appropriate selection for new designs. This part carries Active product status, ensuring long-term availability and manufacturer support. It meets AEC-Q101 automotive qualification requirements and maintains full ROHS3 compliance with unlimited moisture sensitivity rating.

For Existing Designs or Inventory Constraints: The SS115L provides electrical and mechanical equivalence to the SS115LHM2G. However, this part is designated Not For New Designs, indicating potential future discontinuation. The SS115L is supplied in Tape & Reel (TR) packaging format, which may require adjustment to assembly processes if the original design specified alternative packaging. Both parts share identical electrical performance, thermal operating range, and compliance certifications.

Compliance Considerations: Both parts maintain ROHS3 compliance and REACH Unaffected status. Both are classified under ECCN EAR99 and HTSUS 8541.10.0080. Automotive grade qualification (AEC-Q101) is maintained across both part numbers, supporting use in automotive applications.

Frequently Asked Questions (FAQ)

Q: Can SS115L be used as a direct replacement for SS115LHM2G in existing circuit designs?

A: Yes, from an electrical and mechanical standpoint. Both parts share identical voltage ratings (150 V), current capacity (1 A), forward voltage characteristics (900 mV @ 1 A), and operating temperature range (-55°C to 150°C). The DO-219AB package and surface mount configuration are identical. The primary consideration is packaging format: SS115L is supplied in Tape & Reel (TR) format, which may differ from the original procurement specification.

Q: What is the significance of the "Not For New Designs" status on SS115L?

A: This designation indicates that Taiwan Semiconductor Corporation does not recommend the SS115L for incorporation into new product designs. While the part remains electrically and mechanically equivalent, this status typically signals potential future discontinuation or reduced manufacturing priority. For new designs, SS115LHM2G (Active status) is the appropriate selection.

Q: Are there any thermal or electrical performance differences between these parts?

A: No. Both parts operate identically across all specified parameters: reverse voltage, forward voltage, leakage current, recovery speed, and junction temperature range. Performance in circuit operation is equivalent.

Q: Does the Tape & Reel (TR) packaging of SS115L affect circuit performance?

A: No. Tape & Reel packaging is a supply format that affects procurement and assembly handling, not electrical or thermal performance. The actual component in the DO-219AB package is identical. Assembly equipment compatibility should be confirmed if the original design specified different packaging.

Q: Are both parts suitable for automotive applications?

A: Yes. Both SS115LHM2G and SS115L carry Automotive grade designation and AEC-Q101 qualification, meeting automotive industry standards for reliability and performance.

Q: What is the inventory status difference between these parts?

A: SS115LHM2G has 860 pieces available in new original inventory. SS115L has 3,400 pieces available in new original inventory. Higher inventory availability on SS115L may support extended production runs, though the Not For New Designs status should be considered for long-term supply planning.
