SS110L Schottky Diode Equivalent & Substitute Parts

Part Overview

The SS110L is a surface mount Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 100 V DC reverse voltage and 1 A average rectified current. This component is classified as "Not For New Designs," indicating it has reached end-of-life status. The SS110L is packaged in the DO-219AB (Sub SMA) form factor and is designed for fast recovery applications with switching speeds of 500 ns or less at currents exceeding 200 mA.

Due to its discontinued design status, equivalent and substitute parts are necessary for ongoing production support, maintenance applications, and design transitions to active product lines. Substitute parts maintain electrical equivalence while offering improved availability and active product support.

Substitute Categories:

Category 1: Manufacturer Recommended Substitute (Package Variant) The SS110LW represents the manufacturer-recommended upgrade path. While maintaining identical electrical specifications, it transitions to the SOD-123W package format, which is an active product with improved availability. This substitute is suitable for new designs and ongoing production where package footprint compatibility can be accommodated.

Category 2: Parametric Equivalents (Same Package, Active Status) The SS110L M2G, SS110L MHG, SS110L MTG, SS110L RFG, SS110L RHG, SS110L RQG, SS110L RTG, SS110L RUG, and SS110L RVG variants maintain identical electrical performance and the original DO-219AB (Sub SMA) package format. These parts differ only in manufacturing date codes and tape reel specifications. All variants are active products with full production support.

Engineering Selection Recommendations

For Existing Designs (Same Package Requirement): Select from the active SS110L variants (M2G, MHG, MTG, RFG, RHG, RQG, RTG, RUG, RVG). These parts provide direct mechanical and electrical compatibility with existing PCB layouts designed for the DO-219AB (Sub SMA) package. All variants carry Active product status, ensuring long-term supply continuity and full manufacturing support. Selection among these variants is based on manufacturing date code availability and tape reel specifications as required by production scheduling.

For New Designs or Package Flexibility: The SS110LW is the manufacturer-recommended substitute, offering Active product status with transition to the SOD-123W package format. This part maintains all electrical specifications while providing improved availability and modern manufacturing processes. Selection of SS110LW requires PCB layout modification to accommodate the SOD-123W footprint.

Compliance Considerations: All substitute parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with current manufacturing and environmental regulations. All parts are classified under ECCN EAR99 and HTSUS 8541.10.0080.

Frequently Asked Questions (FAQ)

Q: Can SS110L be directly replaced with SS110LW? A: Electrical substitution is complete. However, SS110LW uses the SOD-123W package while SS110L uses DO-219AB (Sub SMA). Direct PCB replacement requires layout modification. If package footprint compatibility is not a constraint, SS110LW is the recommended upgrade path due to its Active product status.

Q: What is the difference between SS110L and its variants (M2G, MHG, MTG, RFG, RHG, RQG, RTG, RUG, RVG)? A: All variants maintain identical electrical specifications and the same DO-219AB package. Differences are limited to manufacturing date codes and tape reel configurations. Selection is based on production scheduling and inventory availability rather than electrical performance.

Q: Are all substitute parts RoHS compliant? A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the reverse leakage current difference between SS110L and SS110LW? A: SS110L specifies 50 µA reverse leakage at 100 V. SS110LW specifies 10 µA reverse leakage at 100 V. Both values are within acceptable operating parameters for Schottky diode applications. The lower leakage in SS110LW reflects modern manufacturing processes.

Q: Can I use SS110L variants interchangeably on the same PCB? A: Yes. All SS110L variants (M2G, MHG, MTG, RFG, RHG, RQG, RTG, RUG, RVG) are mechanically and electrically interchangeable. They share identical package geometry (DO-219AB), electrical ratings, and performance characteristics.

Q: What is the moisture sensitivity level for these parts? A: All parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply without special moisture control requirements.

Q: Why is SS110L marked "Not For New Designs"? A: This designation indicates the part has reached end-of-life status. Existing inventory remains available for production support and maintenance applications. New designs should transition to active alternatives such as SS110LW or the active SS110L variants.
