SS115L RHG Schottky Diode Equivalent & Substitute Parts

Part Overview

The SS115L RHG is a surface mount Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, designed for applications requiring fast recovery characteristics and low forward voltage drop. This component operates at 150 V DC reverse voltage with 1 A average rectified current capacity. The part is currently in Active product status with 768 pieces available in new original inventory.

Identification of equivalent and substitute parts becomes necessary when the primary part number is unavailable, when alternative packaging formats are required for manufacturing processes, or when design flexibility permits selection from qualified alternatives within the same electrical and mechanical parameter range.

Substitute Part Grouping Explanation

Substitution of the SS115L RHG 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
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 50 µA @ 150 V
• Technology: Schottky

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)

The SS115L RHG from Taiwan Semiconductor Corporation qualifies as a parametric equivalent to itself when supplied in alternative packaging formats. The substitute part SS115L maintains identical electrical and mechanical specifications while differing only in packaging configuration (Tape & Reel versus standard packaging).

Engineering Selection Recommendations

For Active Production and New Designs: The SS115L RHG maintains Active product status and is the preferred selection for new circuit designs and ongoing production. This part number is supported for long-term availability and is recommended for applications where design continuity and supplier support are required.

For Alternative Packaging Requirements: The SS115L substitute part provides identical electrical and mechanical performance within the DO-219AB Sub SMA package format. This part is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. However, the SS115L carries a "Not For New Designs" product status designation, indicating that Taiwan Semiconductor Corporation does not recommend this part number for new design implementations. This part may be selected only when existing inventory requirements or specific manufacturing process constraints necessitate Tape & Reel packaging and when design legacy support is acceptable.

Compliance Considerations: Both the main part and substitute maintain ROHS3 compliance, REACH Unaffected status, and MSL Level 1 (Unlimited) moisture sensitivity rating. These certifications are identical across both part numbers, permitting direct substitution from a regulatory and environmental standpoint.

Frequently Asked Questions (FAQ)

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

A: The SS115L provides identical electrical performance and mechanical compatibility within the DO-219AB Sub SMA package. However, the SS115L carries "Not For New Designs" status. Direct substitution is electrically and mechanically valid but should be evaluated against design support and long-term availability requirements.

Q: What is the primary difference between SS115L RHG and SS115L?

A: The primary difference is packaging format. SS115L RHG is supplied in standard packaging, while SS115L is supplied in Tape & Reel (TR) format. All electrical parameters, mechanical dimensions, and compliance certifications are identical.

Q: Are there any temperature or voltage derating considerations when substituting between these part numbers?

A: No. Both parts operate across the identical temperature range (-55°C to 150°C junction temperature) and maintain the same voltage and current ratings. No derating adjustments are required for substitution.

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

A: No. Tape & Reel packaging is a supply format used for automated assembly processes. Once the component is removed from the reel and soldered to the circuit board, electrical and thermal performance is identical to standard packaging.

Q: Are both parts RoHS compliant?

A: Yes. Both SS115L RHG and SS115L are ROHS3 compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

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

A: This designation indicates that Taiwan Semiconductor Corporation does not recommend the SS115L for new circuit design implementations. The part may be used for legacy design support, existing inventory management, or when specific manufacturing constraints require Tape & Reel packaging. For new designs, SS115L RHG (Active status) is the recommended selection.

Q: Can I mix SS115L RHG and SS115L components in the same production batch?

A: Yes. Both parts are electrically and mechanically equivalent within the specified parameters. However, supply chain and inventory management practices should account for the different product status designations and packaging formats.
