Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SS14LSHRVG is determined by matching the following critical parameters across all candidate parts:

Mandatory Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 40 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 550 mV @ 1 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Package / Case: SOD-123H
• Supplier Device Package: SOD-123HE
• Operating Temperature - Junction: -55°C ~ 150°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All identified substitute parts meet these mandatory electrical and mechanical criteria. Variations in secondary parameters such as Current - Reverse Leakage @ Vr and Capacitance @ Vr, F do not disqualify substitution when primary performance specifications align.

Parameter Comparison

Engineering Selection Recommendations

SS14LS (Taiwan Semiconductor Corporation)

The SS14LS is an Active product from Taiwan Semiconductor Corporation with identical electrical specifications to the SS14LSHRVG across all primary parameters. This part demonstrates equivalent performance in voltage rating, current capacity, forward voltage drop, and switching speed. The SS14LS maintains ROHS3 compliance and MSL 1 classification. Inventory availability is significantly higher at 32,931 pieces. This part is suitable for applications where automotive-grade qualification is not a design requirement.

SS1040HE_R1_00001 (Panjit International Inc.)

The SS1040HE_R1_00001 is an Active product from Panjit International Inc. that meets all mandatory electrical and mechanical specifications. This part exhibits lower reverse leakage current (30 µA @ 40 V versus 400 µA @ 40 V) and higher capacitance (155 pF @ 0V, 1MHz versus 80 pF @ 4V, 1MHz). These secondary parameter differences do not affect substitution eligibility. The part maintains ROHS3 compliance and MSL 1 classification. Inventory availability is 4,200 pieces. This part is suitable for applications where reduced leakage current provides circuit performance benefits.

SS14FP (onsemi)

The SS14FP is classified as Not For New Designs and carries automotive-grade qualification under AEC-Q101 standard. This part meets all mandatory electrical and mechanical specifications with identical voltage, current, and temperature ratings. The SS14FP exhibits lower capacitance (54 pF @ 4V, 1MHz) and includes specified reverse recovery time (6 ns). ROHS3 compliance and MSL 1 classification are maintained. Inventory availability is 23,400 pieces. This part is restricted to legacy design support and field replacement applications only.

Frequently Asked Questions (FAQ)

Q: Can SS14LS be used as a direct replacement for SS14LSHRVG in automotive applications?

A: The SS14LS meets all electrical and mechanical specifications required for substitution. However, the SS14LS does not carry automotive-grade qualification or AEC-Q101 certification. If automotive qualification is a design requirement, the SS14LS is not suitable. For non-automotive applications, the SS14LS is a valid substitute.

Q: What is the significance of the lower reverse leakage current in SS1040HE_R1_00001?

A: The SS1040HE_R1_00001 exhibits 30 µA reverse leakage current compared to 400 µA in the SS14LSHRVG. Lower reverse leakage reduces parasitic current paths in the circuit. This characteristic may benefit applications sensitive to standby power consumption or leakage-dependent circuit behavior. The difference does not affect the part's substitution eligibility.

Q: Why is SS14FP marked as Not For New Designs?

A: The SS14FP carries a product status designation of Not For New Designs, indicating that the manufacturer has discontinued active development and recommends alternative parts for new circuit designs. This part remains available for legacy system support and field replacement of existing installations. New designs should utilize SS14LSHRVG, SS14LS, or SS1040HE_R1_00001.

Q: Are all substitute parts compatible with the SOD-123HE package footprint?

A: All identified substitute parts use the SOD-123H package with SOD-123HE supplier device package designation. Mechanical compatibility with existing PCB layouts and assembly processes is confirmed across all substitutes.

Q: What compliance certifications apply to each substitute part?

A: All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity classification. The SS14LSHRVG and SS14FP carry automotive-grade qualification and AEC-Q101 certification. The SS14LS and SS1040HE_R1_00001 do not carry automotive qualification. Selection should align with application compliance requirements.

Q: How does operating temperature range affect substitution decisions?

A: All substitute parts operate across the identical temperature range of -55°C to 150°C junction temperature. Operating temperature compatibility is confirmed across all candidates and does not differentiate substitution suitability.
