Substitute Part Grouping Explanation

Substitution of the SS115LHRFG is determined by electrical and mechanical parameter equivalence across the following criteria:

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
• Technology: Schottky

Mechanical Parameters (Must Match):

• Package / Case: DO-219AB
• Supplier Device Package: Sub SMA
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

The SS115L meets all electrical, mechanical, and compliance requirements for direct substitution with the SS115LHRFG. The primary distinction is packaging configuration: SS115LHRFG is supplied in standard packaging, while SS115L is supplied in Tape & Reel (TR) format. Both parts share identical electrical performance and automotive-grade qualification.

Parameter Comparison

Engineering Selection Recommendations

SS115L Substitution Criteria:

The SS115L is electrically and mechanically equivalent to the SS115LHRFG across all critical parameters: reverse voltage rating, forward current capacity, forward voltage drop, switching speed, reverse leakage current, package type, and operating temperature range. Both parts are ROHS3 compliant with MSL 1 rating and REACH unaffected status.

The primary distinction is product status: SS115LHRFG is designated for active production, while SS115L is marked "Not For New Designs." This designation indicates that SS115L is available for existing designs and legacy applications but should not be selected for new circuit development.

Selection Logic:

For ongoing production of existing designs using SS115LHRFG, the SS115L provides full electrical and mechanical compatibility. The Tape & Reel packaging of SS115L is suitable for high-volume automated assembly processes. For new design initiatives, continued use of SS115LHRFG is appropriate given its active product status.

Both parts maintain automotive-grade qualification and AEC-Q101 compliance, supporting applications requiring automotive-level reliability standards.

Frequently Asked Questions (FAQ)

Q: Can SS115L be used as a direct replacement for SS115LHRFG in existing circuit designs?

A: Yes. The SS115L provides electrical and mechanical equivalence across all specified parameters: 150 V reverse voltage, 1 A average rectified current, 900 mV forward voltage drop at 1 A, fast recovery switching speed, and identical DO-219AB Sub SMA package configuration. Both parts operate across the same temperature range (-55°C to 150°C) and maintain ROHS3 compliance with MSL 1 rating.

Q: What is the difference between SS115LHRFG and SS115L?

A: The electrical and mechanical specifications are identical. The primary difference is packaging configuration: SS115LHRFG is supplied in standard packaging format, while SS115L is supplied in Tape & Reel (TR) format for automated assembly. Additionally, SS115LHRFG maintains active product status, while SS115L is designated "Not For New Designs."

Q: Is SS115L suitable for new product designs?

A: SS115L carries a "Not For New Designs" designation. For new circuit development, SS115LHRFG is the appropriate selection due to its active product status. SS115L is available for sustaining production of existing designs.

Q: Are there compliance or qualification differences between these parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and maintain MSL 1 (Unlimited) moisture sensitivity rating. Both support automotive-grade applications with AEC-Q101 qualification.

Q: What packaging format should be selected for high-volume production?

A: SS115L in Tape & Reel (TR) format is optimized for high-volume automated surface mount assembly. SS115LHRFG in standard packaging is suitable for lower-volume or manual assembly processes. Both maintain identical electrical performance and package footprint (DO-219AB Sub SMA).

Q: Can these parts be used interchangeably in automotive applications?

A: Yes, within the constraints of product status. Both parts meet automotive-grade requirements and AEC-Q101 qualification. For new automotive designs, SS115LHRFG is the recommended selection. For existing automotive applications, SS115L provides full compatibility.
