SS1H10LS Equivalent & Substitute Parts

Part Overview

The SS1H10LS is a Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 100V DC reverse voltage and 1A average rectified current in a surface mount SOD-123HE package. This component is classified as Active product status and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified when alternative manufacturers or part variants provide identical or compatible electrical and mechanical specifications within the defined parameter tolerances for Schottky diode rectifiers. Substitution becomes necessary due to supply chain availability, inventory levels, or design flexibility requirements while maintaining circuit performance and reliability standards.

Substitute Part Grouping Explanation

Substitution of the SS1H10LS is determined by equivalence across the following critical parameters:

Electrical Equivalence Criteria:

Voltage - DC Reverse (Vr) (Max): 100V
Current - Average Rectified (Io): 1A
Voltage - Forward (Vf) (Max) @ If: 800 mV @ 1A
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
Operating Temperature - Junction: -55°C to 150°C

Mechanical Equivalence Criteria:

Package / Case: SOD-123H
Mounting Type: Surface Mount
Supplier Device Package: SOD-123HE

Compliance Criteria:

Technology: Schottky
RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level (MSL): 1 (Unlimited)

Parts meeting all electrical, mechanical, and compliance criteria are classified as parametric equivalents. Variations in reverse leakage current and capacitance specifications do not disqualify substitution when all primary electrical parameters remain within specification.

Engineering Selection Recommendations

SS110LS (Taiwan Semiconductor Corporation) Active product status with parametric equivalence to SS1H10LS. All electrical and mechanical specifications align with primary design requirements. Reverse leakage current of 50 µA represents acceptable variation within Schottky diode rectifier specifications. Suitable for new designs and production applications.

SS110LSH (Taiwan Semiconductor Corporation) Active product status with automotive-grade qualification (AEC-Q101) and parametric equivalence to SS1H10LS. Identical electrical specifications to SS110LS with additional automotive qualification. Appropriate for applications requiring automotive-grade components or enhanced reliability standards.

S110FP (onsemi) Product status classified as Not For New Designs. While electrical and mechanical specifications are equivalent to SS1H10LS, this part is not recommended for new circuit designs. Existing designs currently utilizing S110FP may continue operation; however, migration to active-status alternatives is advised for long-term supply chain stability.

SS10100HE_R1_00001 (Panjit International Inc.) Active product status with parametric equivalence to SS1H10LS. Reverse leakage current of 30 µA and capacitance specification of 100 pF @ 0V, 1MHz represent acceptable variations. Suitable for applications where alternative manufacturer sourcing is required or preferred.

Frequently Asked Questions (FAQ)

Q: Can SS110LS be used as a direct replacement for SS1H10LS? A: Yes. SS110LS meets all electrical and mechanical equivalence criteria. Both components share identical voltage ratings (100V), current ratings (1A), forward voltage specifications (800 mV @ 1A), and package configuration (SOD-123H surface mount). Both are Active product status and RoHS3 compliant.

Q: What is the difference between SS110LS and SS110LSH? A: SS110LSH includes automotive-grade qualification (AEC-Q101) and is designated as automotive-grade component. Electrical specifications are identical. Selection between these parts depends on application requirements for automotive qualification and enhanced reliability standards.

Q: Why is S110FP marked as Not For New Designs? A: S110FP carries a product status designation of Not For New Designs. This classification indicates the manufacturer is discontinuing active support for new applications. Existing designs may continue using this part; however, new circuit designs should utilize active-status alternatives such as SS110LS or SS110LSH.

Q: Are there differences in reverse leakage current between substitute parts? A: Yes. SS1H10LS specifies 1 µA @ 100V reverse leakage. Substitute parts specify higher values: SS110LS and SS110LSH at 50 µA, S110FP at 50 µA, and SS10100HE_R1_00001 at 30 µA. These variations remain within acceptable Schottky diode rectifier specifications and do not disqualify substitution.

Q: Can I use SS10100HE_R1_00001 from Panjit International Inc. in place of the Taiwan Semiconductor Corporation part? A: Yes. SS10100HE_R1_00001 meets all electrical and mechanical equivalence criteria. It is manufactured by a different supplier (Panjit International Inc.) but maintains identical voltage, current, and package specifications. This part is Active product status and RoHS3 compliant.

Q: What packaging format is used for all substitute parts? A: All substitute parts use SOD-123H package with surface mount configuration and SOD-123HE supplier device package designation. This ensures mechanical compatibility with existing PCB layouts and assembly processes.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts carry RoHS3 compliance status, matching the environmental and regulatory requirements of the primary SS1H10LS component.

Q: What is the operating temperature range for substitute parts? A: All substitute parts maintain the same operating temperature range as SS1H10LS: -55°C to 150°C junction temperature. This ensures thermal performance equivalence across all applications.
