Substitute Part Grouping Explanation

Substitution of the SS115LW is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part SS115LWHRVG is classified as a parametric equivalent because it maintains identical specifications across the following key criteria:

• Reverse voltage rating: 150 V
• Average rectified current: 1 A
• Forward voltage drop: 950 mV @ 1 A
• Recovery speed classification: Fast Recovery ≤ 500ns, > 200mA
• Reverse leakage current: 10 µA @ 150 V
• Junction temperature range: -55°C to 150°C
• Package designation: SOD-123W
• Surface mount configuration
• Schottky diode technology
• RoHS3 compliance
• MSL 1 classification

Both parts share the same base product number (SS115) and are manufactured by Taiwan Semiconductor Corporation. The substitute part is suitable for direct replacement in applications where the SS115LW is specified.

Parameter Comparison

Engineering Selection Recommendations

Both SS115LW and SS115LWHRVG are active products with identical electrical and mechanical specifications. Selection between these parts is based on availability and supply chain requirements rather than technical differentiation.

The SS115LW maintains 6651 pieces in current inventory stock. The SS115LWHRVG substitute maintains 4028 pieces in current inventory stock. Both parts carry ROHS3 compliance certification and REACH unaffected status, confirming regulatory alignment for industrial and commercial applications.

The SOD-123W surface mount package is standard across both parts, ensuring mechanical compatibility with existing PCB layouts and assembly processes. The MSL 1 classification indicates unlimited shelf life under standard storage conditions, eliminating moisture-related handling constraints.

For applications requiring the 150 V / 1 A Schottky rectifier specification with fast recovery characteristics, either part number satisfies the complete technical requirement set.

Frequently Asked Questions (FAQ)

Q: Can SS115LWHRVG be used as a direct replacement for SS115LW?

A: Yes. SS115LWHRVG is a parametric equivalent with identical electrical ratings (150 V reverse voltage, 1 A average rectified current, 950 mV forward voltage drop), recovery speed classification, reverse leakage characteristics, and operating temperature range. Both use the SOD-123W surface mount package and share the same base product number (SS115).

Q: Are there differences in package dimensions between SS115LW and SS115LWHRVG?

A: No. Both parts use the SOD-123W package designation. Package dimensions and land pattern requirements are identical, ensuring direct PCB compatibility without layout modifications.

Q: What is the significance of the "LWHRVG" suffix in the substitute part number?

A: The suffix indicates manufacturing or qualification variant coding applied by Taiwan Semiconductor Corporation. The electrical and mechanical specifications remain identical to the base SS115LW designation. The suffix does not affect functional performance or substitution eligibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SS115LW and SS115LWHRVG carry ROHS3 compliance certification and REACH unaffected status. Moisture sensitivity level is MSL 1 (unlimited) for both parts, eliminating differential handling or storage requirements.

Q: Which part should be selected based on availability?

A: Selection is determined by current inventory status and procurement lead time requirements. SS115LW currently maintains higher stock levels (6651 pieces) compared to SS115LWHRVG (4028 pieces). For time-sensitive applications, the part with greater available inventory is the appropriate selection.

Q: Are the forward voltage characteristics identical between these parts?

A: Yes. Both parts specify 950 mV maximum forward voltage drop at 1 A forward current. Reverse leakage current is specified at 10 µA @ 150 V for both parts, confirming identical DC operating characteristics.

Q: Can these parts be used in high-temperature applications?

A: Yes. Both parts are rated for junction temperatures from -55°C to 150°C, supporting operation across extended industrial temperature ranges. The fast recovery characteristic (≤ 500ns, > 200mA) is maintained across the full temperature range.
