SS115LHRTG Equivalent & Substitute Parts

Part Overview

The SS115LHRTG is a Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, designed for surface mount applications in the Sub SMA package format. This component is rated for 150 V DC reverse voltage with 1 A average rectified current and features fast recovery characteristics suitable for high-frequency switching applications. The part maintains Active product status and carries automotive-grade qualification under AEC-Q101 standards.

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 SS115LHRTG has identified parametric equivalents that maintain identical electrical performance while offering alternative packaging or availability options.

Substitute Part Grouping Explanation

Substitution eligibility for the SS115LHRTG 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
• Operating Temperature - Junction: -55°C to 150°C

Physical & Mechanical Parameters (Must Match Exactly):

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

Compliance & Certification (Must Match Exactly):

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

The SS115L qualifies as a parametric equivalent because it maintains identical electrical specifications, package format, and compliance certifications. The primary distinction is packaging configuration (Tape & Reel versus bulk) and product status classification.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (SS115LHRTG): The SS115LHRTG is the recommended choice for new designs and active production programs. This part maintains Active product status, ensuring long-term availability and manufacturer support. It carries full automotive-grade qualification under AEC-Q101 standards and meets ROHS3 compliance requirements. The part is available in bulk packaging configuration.

Substitute Selection (SS115L): The SS115L qualifies as a direct parametric equivalent for applications where the primary part is unavailable or when Tape & Reel packaging is required for automated assembly processes. This part maintains identical electrical specifications, package format (DO-219AB Sub SMA), and compliance certifications. However, the SS115L carries a "Not For New Designs" product status designation, indicating it is intended for legacy system support or replacement applications only. Use of SS115L in new design programs requires documented justification and approval from design engineering.

Compliance Considerations: Both parts maintain ROHS3 compliance, REACH Unaffected status, and MSL Level 1 (Unlimited) moisture sensitivity classification. Automotive-grade qualification is confirmed for the primary part. Substitution does not introduce compliance risks for regulated applications.

Frequently Asked Questions (FAQ)

Q: Can SS115L be used as a direct replacement for SS115LHRTG in new designs?

A: SS115L maintains identical electrical and mechanical specifications and qualifies as a parametric equivalent. However, SS115L carries "Not For New Designs" product status. New design applications should specify SS115LHRTG. Substitution of SS115L in new designs requires documented engineering approval.

Q: What is the difference between SS115LHRTG and SS115L packaging?

A: The primary packaging difference is configuration: SS115LHRTG is supplied in bulk format, while SS115L is supplied in Tape & Reel (TR) configuration. Both use identical DO-219AB Sub SMA package format and are compatible with standard surface mount assembly equipment. Selection depends on manufacturing process requirements and inventory management practices.

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

A: No. Both SS115LHRTG and SS115L maintain identical compliance status: ROHS3 Compliant, REACH Unaffected, and MSL Level 1 (Unlimited). Both carry automotive-grade qualification under AEC-Q101 standards.

Q: What electrical parameters must match for substitution eligibility?

A: Substitution requires exact equivalence across reverse voltage (150 V), average rectified current (1 A), forward voltage (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). Any deviation in these parameters disqualifies substitution.

Q: Can SS115L be used in automotive applications?

A: SS115L maintains AEC-Q101 automotive-grade qualification identical to SS115LHRTG. Automotive application compatibility is confirmed. Product status designation does not affect automotive qualification or performance characteristics.

Q: What is the inventory status of these parts?

A: SS115LHRTG maintains 1014 pieces in stock as new original inventory. SS115L maintains 3400 pieces in stock as new original inventory. Availability should be confirmed with the supplier for current production requirements.
