Engineering Selection Recommendations

SS110-LTP (Micro Commercial Co)

The SS110-LTP is the direct equivalent from the original manufacturer. It maintains identical electrical specifications to the SS110E-TP across all critical parameters: 100V reverse voltage, 1A forward current, 850mV forward voltage drop, and -55°C to 150°C operating range. The primary distinction is product status transition from obsolete to active, with significantly higher inventory availability (20,300 units). Packaging is specified as Tape & Reel (TR) in DO-214AC (SMA) format. ROHS3 compliance and REACH unaffected status are maintained. This part is the preferred direct replacement for design continuity.

S100W_R1_00001 (Panjit International Inc.)

The S100W_R1_00001 provides functional equivalence with identical voltage and current ratings, forward voltage specification, and thermal operating range. Manufactured by Panjit International Inc., this part maintains ROHS3 compliance and REACH unaffected status. Reverse leakage current specification matches the main part at 500 µA @ 100V. Capacitance data is not provided for this part. Inventory availability is lower at 1,400 units. This part is suitable for applications where multi-source qualification is required.

VS-10MQ100-M3/5AT (Vishay General Semiconductor - Diodes Division)

The VS-10MQ100-M3/5AT meets all mandatory electrical and thermal specifications with 100V reverse voltage and 1A forward current rating. This part exhibits superior performance characteristics: forward voltage drop is reduced to 780 mV @ 1A (compared to 850 mV), and reverse leakage current is lower at 100 µA @ 100V. Capacitance is specified at 38pF @ 10V, 1MHz. ROHS3 compliance and REACH unaffected status are confirmed. Inventory availability is highest among substitutes at 82,545 units. This part is suitable for applications where lower forward voltage drop and reduced leakage current provide performance benefits.

All three substitutes are active products with confirmed ROHS3 compliance and REACH unaffected status, ensuring regulatory compliance for new designs and production.

Frequently Asked Questions (FAQ)

Q: Can the SS110E-TP be directly replaced with the SS110-LTP?

A: Yes. The SS110-LTP is the direct equivalent from Micro Commercial Co with identical electrical specifications across all critical parameters: 100V reverse voltage, 1A average rectified current, 850mV forward voltage drop at 1A, and -55°C to 150°C operating temperature range. Both parts use the DO-214AC (SMA) package and maintain ROHS3 compliance. The primary difference is product status transition from obsolete to active.

Q: What are the key differences between the three substitute options?

A: All three substitutes maintain identical reverse voltage (100V), forward current (1A), and operating temperature range (-55°C to 150°C). The VS-10MQ100-M3/5AT from Vishay exhibits lower forward voltage drop (780 mV vs. 850 mV) and lower reverse leakage current (100 µA vs. 500 µA), providing performance advantages in applications sensitive to power dissipation or leakage. The S100W_R1_00001 from Panjit matches the original specifications exactly. Inventory availability varies significantly, with Vishay offering the highest stock level.

Q: Are all substitutes compatible with the same PCB footprint?

A: Yes. All substitutes use the DO-214AC (SMA) package, which maintains identical physical dimensions and pin configuration. PCB footprints designed for the SS110E-TP are directly compatible with all three substitute parts without layout modifications.

Q: Do all substitutes meet the same compliance standards?

A: Yes. All three substitutes are ROHS3 compliant and REACH unaffected, matching the regulatory status of the SS110E-TP. All parts carry EAR99 ECCN classification and 8541.10.0080 HTSUS code.

Q: Which substitute should be selected for new designs?

A: Selection depends on application requirements. For direct replacement with identical specifications, the SS110-LTP is recommended. For applications where lower forward voltage drop reduces power dissipation, the VS-10MQ100-M3/5AT is suitable. For multi-source qualification, the S100W_R1_00001 provides an alternative from a different manufacturer while maintaining equivalent electrical performance.

Q: What is the significance of the forward voltage difference between substitutes?

A: The forward voltage drop (Vf) determines power dissipation in the diode. The VS-10MQ100-M3/5AT at 780 mV dissipates less power than the SS110-LTP and S100W_R1_00001 at 850 mV. In high-current or continuous-operation applications, this 70 mV difference results in measurable thermal benefits. The choice depends on thermal design requirements and application duty cycle.

Q: Are there any temperature or voltage derating considerations?

A: All substitutes operate across the identical junction temperature range of -55°C to 150°C and maintain 100V reverse voltage rating. No derating adjustments are required when substituting between these parts. Thermal management design should account for the forward voltage drop specification of the selected part.
