Substitute Part Grouping Explanation

Substitution of the SS115LHR3G is permissible with the SS115L part number based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is determined by the following 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

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)
• REACH Status: REACH Unaffected

The SS115L maintains identical specifications across all parameters listed above, establishing it as a parametric equivalent suitable for direct substitution in applications where the SS115LHR3G is specified.

Engineering Selection Recommendations

Primary Selection: SS115LHR3G

The SS115LHR3G is the preferred component for new designs and production applications. This part maintains Active product status, indicating ongoing manufacturer support, continued availability, and compliance with current industry standards. The part carries AEC-Q101 automotive qualification, establishing its suitability for automotive-grade applications. Current inventory of 783 units supports immediate procurement requirements.

Substitute Selection: SS115L

The SS115L is a parametric equivalent suitable for substitution in existing designs or when SS115LHR3G availability is constrained. This part number is designated as Not For New Designs, indicating it remains available for legacy applications and inventory management purposes but should not be selected for new product development. The SS115L maintains identical electrical performance, mechanical compatibility, and environmental specifications as the SS115LHR3G. Higher inventory availability (3400 units) may support extended production runs or supply chain continuity requirements.

Compliance Considerations:

Both parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment for applications subject to environmental and hazardous substance restrictions. Moisture Sensitivity Level 1 (Unlimited) classification permits standard handling and storage procedures without specialized desiccant packaging requirements.

Frequently Asked Questions (FAQ)

Q: Can SS115L be used as a direct replacement for SS115LHR3G in production?

A: Yes. The SS115L is a parametric equivalent with identical electrical specifications (150 V reverse voltage, 1 A average rectified current, 900 mV forward voltage), identical mechanical packaging (DO-219AB Sub SMA), and identical environmental operating range (-55°C to 150°C). Direct substitution is permissible from an electrical and mechanical standpoint. However, the SS115L carries Not For New Designs status, making it suitable only for legacy applications or inventory management.

Q: What are the critical parameters that determine substitution eligibility?

A: Substitution eligibility is determined by exact matching of: (1) Voltage - DC Reverse (Vr) (Max) at 150 V, (2) Current - Average Rectified (Io) at 1 A, (3) Voltage - Forward (Vf) (Max) @ If at 900 mV @ 1 A, (4) Speed classification as Fast Recovery ≤ 500ns, > 200mA (Io), (5) Current - Reverse Leakage @ Vr at 50 µA @ 150 V, (6) Package / Case as DO-219AB, (7) Mounting Type as Surface Mount, and (8) Operating Temperature - Junction range of -55°C to 150°C.

Q: Are there differences in packaging or handling between SS115LHR3G and SS115L?

A: No. Both parts use identical packaging (DO-219AB Sub SMA) and are supplied in Tape & Reel (TR) format. Both maintain Moisture Sensitivity Level 1 (Unlimited), eliminating the need for specialized desiccant storage or handling procedures. PCB assembly processes, reflow profiles, and component placement procedures remain unchanged between the two part numbers.

Q: What is the significance of the product status difference between these parts?

A: SS115LHR3G carries Active status, indicating current manufacturer support and suitability for new product designs. SS115L carries Not For New Designs status, indicating the part remains available for existing applications but should not be selected for new development. This distinction reflects manufacturer lifecycle management and does not indicate functional or performance differences.

Q: Can these parts be used in automotive applications?

A: Yes. Both SS115LHR3G and SS115L carry AEC-Q101 automotive qualification, establishing their suitability for automotive-grade applications. This qualification confirms compliance with automotive industry reliability and quality standards.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts maintain identical RoHS3 compliance status and REACH Unaffected classification. Both are suitable for applications subject to environmental and hazardous substance restrictions in regulated markets.
