SS115L R3G Equivalent & Substitute Parts

Part Overview

The SS115L R3G 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 a 1 A average rectified current rating and features fast recovery characteristics suitable for high-frequency switching applications.

The SS115L R3G maintains Active product status and is fully compliant with RoHS3 and REACH regulations. Identification of equivalent and substitute parts is necessary to support procurement flexibility, manage supply chain continuity, and accommodate design variations across manufacturing batches and packaging configurations.

Substitute Part Grouping Explanation

Substitution of the SS115L R3G is determined by electrical and mechanical parameter equivalence within the Schottky rectifier diode category. The following parameters establish substitution validity:

Electrical Parameters (Critical):

• 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 (Critical):

• Package / Case: DO-219AB (Sub SMA)
• Mounting Type: Surface Mount
• Technology: Schottky

Compliance Parameters:

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

Substitute parts must match all critical electrical and mechanical parameters. Packaging configuration (Tape & Reel versus individual units) does not affect electrical substitution eligibility but reflects inventory and procurement format differences.

Engineering Selection Recommendations

SS115L R3G (Primary Selection): The SS115L R3G is designated as Active product status and is the preferred selection for new designs and ongoing production. This part number maintains full compliance with RoHS3 and REACH regulations and carries unlimited moisture sensitivity classification (MSL 1), indicating no special storage or handling requirements.

SS115L (Substitute Selection): The SS115L is electrically and mechanically equivalent to the SS115L R3G, matching all critical parameters including voltage rating, current capacity, forward voltage drop, recovery speed, and operating temperature range. However, this part is designated as Not For New Designs, indicating it is retained for legacy system support and existing production lines only.

The SS115L is available in Tape & Reel packaging format, which differs from the main part's packaging configuration but does not affect electrical performance. This substitute is suitable for replacement in existing applications where the SS115L R3G is currently deployed, provided that procurement and inventory management systems accommodate the Not For New Designs status.

Both parts maintain identical RoHS3 compliance and MSL 1 classification, ensuring compatibility with current manufacturing and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can the SS115L be used as a direct replacement for the SS115L R3G in new designs?

A: No. The SS115L carries a Not For New Designs product status designation. For new designs, the SS115L R3G (Active status) is the appropriate selection. The SS115L is reserved for legacy system support and existing production continuity.

Q: Are the electrical specifications identical between SS115L R3G and SS115L?

A: Yes. Both parts are electrically equivalent, with matching voltage ratings (150 V), current capacity (1 A), forward voltage drop (900 mV @ 1 A), recovery speed (Fast Recovery ≤ 500ns), reverse leakage current (50 µA @ 150 V), and operating temperature range (-55°C to 150°C).

Q: What is the difference between the packaging formats listed for these parts?

A: The SS115L R3G is supplied in standard packaging format, while the SS115L is available in Tape & Reel (TR) configuration. Both use the DO-219AB (Sub SMA) package case. Tape & Reel format is a continuous strip suitable for automated assembly processes, whereas standard packaging may be supplied in alternative formats. This difference affects procurement and handling procedures but not electrical performance.

Q: Do both parts meet current environmental and compliance standards?

A: Yes. Both the SS115L R3G and SS115L are ROHS3 Compliant and REACH Unaffected. Both carry Moisture Sensitivity Level 1 (Unlimited), indicating no special storage or handling requirements beyond standard component care.

Q: What is the base product number for these parts?

A: The base product number is SS115. Both the SS115L R3G and SS115L are variants of this base product, differentiated by packaging and product status designations.

Q: Can I substitute the SS115L for the SS115L R3G in existing production?

A: Substitution is electrically valid due to parameter equivalence. However, procurement and design documentation must reflect the Not For New Designs status of the SS115L. Existing production lines currently using the SS115L R3G should maintain that part number for consistency unless supply constraints necessitate substitution, in which case engineering and quality documentation must be updated accordingly.
