Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the S1KL are identified through strict parametric matching across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain constant:

• Voltage - DC Reverse (Vr) (Max): 800 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1 A
• Reverse Recovery Time (trr): 1.8 µs
• Current - Reverse Leakage @ Vr: 5 µA @ 800 V
• Capacitance @ Vr, F: 9 pF @ 4V, 1MHz
• Package / Case: DO-219AB (Sub SMA)
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 175°C
• Technology: Standard
• RoHS Status: ROHS3 Compliant

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The S1KL substitute part identified in this reference maintains full parametric equivalence with the main part number across all electrical and mechanical specifications. Both the main part and substitute are manufactured by Taiwan Semiconductor Corporation and carry Active product status, ensuring continued availability and manufacturing support.

Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The substitute part is available in Cut Tape (CT) packaging, which may differ from the main part's packaging configuration but does not affect electrical or mechanical compatibility when used in surface mount applications with DO-219AB package specifications.

Selection between the main part and substitute should be based on packaging availability, inventory levels, and procurement requirements rather than electrical performance, as all critical parameters are identical.

Frequently Asked Questions (FAQ)

Q: Can the S1KL substitute part be used interchangeably with the main S1KL part number?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, including voltage rating (800 V), current rating (1 A), forward voltage drop (1.1 V @ 1 A), reverse recovery time (1.8 µs), and package type (DO-219AB Sub SMA). They are functionally interchangeable in surface mount applications.

Q: What is the difference between the main part and the substitute part?

A: The primary difference is packaging format. The main part is supplied in standard packaging, while the substitute is supplied in Cut Tape (CT) format. Both parts are identical in electrical performance and mechanical compatibility.

Q: Are there any temperature or compliance differences between the parts?

A: No. Both parts operate across the same junction temperature range (-55°C to 175°C) and carry identical RoHS3 compliance and REACH unaffected status.

Q: Can I use the substitute part in a design originally specified for the main part?

A: Yes. The substitute part meets all electrical and mechanical requirements for applications designed for the S1KL. No circuit modifications or re-qualification are required.

Q: What packaging options are available for the S1KL?

A: The main part is available in standard packaging, while the substitute is available in Cut Tape (CT) format. Both use the DO-219AB Sub SMA package case.

Q: Are both parts manufactured by the same company?

A: Yes. Both the main part and substitute are manufactured by Taiwan Semiconductor Corporation.
