S1KL RUG Equivalent & Substitute Parts

Part Overview

The S1KL RUG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 800 V DC reverse voltage and 1 A average rectified current. This surface mount component operates across a junction temperature range of -55°C to 175°C and is packaged in the Sub SMA form factor (DO-219AB). The device is classified as Active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across critical parameters including reverse voltage rating, forward current capacity, forward voltage drop, and thermal operating range. Packaging format variations may exist while preserving functional interchangeability within specified application constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the S1KL RUG are identified based on strict electrical and mechanical parameter equivalence. The substitution criteria are defined by the following key parameters:

Electrical Parameters (Must Match):

• 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

Mechanical Parameters (Must Match):

• Package / Case: DO-219AB (Sub SMA)
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 175°C

Compliance Parameters (Must Match):

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

Packaging format variations (Tape & Reel versus Cut Tape) do not affect functional interchangeability when all electrical and mechanical parameters remain identical. The base product number S1K identifies the core diode design across all equivalent variants.

Parameter Comparison

Engineering Selection Recommendations

The S1KL substitute part maintains complete electrical and mechanical equivalence to the S1KL RUG across all specified parameters. Both components are manufactured by Taiwan Semiconductor Corporation and carry identical Active product status with ROHS3 compliance certification.

The primary distinction between these parts is the packaging format: S1KL RUG is supplied in Tape & Reel (TR) configuration, while the substitute S1KL is supplied in Cut Tape (CT) configuration. This packaging difference does not affect component functionality, electrical performance, or thermal characteristics.

Both parts satisfy identical compliance requirements including ROHS3 status, REACH unaffected classification, and unlimited moisture sensitivity rating (MSL 1). The base product number S1K confirms design equivalence across both variants.

Selection between these parts should be based on procurement requirements, assembly process compatibility, and inventory availability rather than electrical or mechanical performance considerations.

Frequently Asked Questions (FAQ)

Q: Can the S1KL (Cut Tape) substitute directly replace the S1KL RUG (Tape & Reel) in production assembly?

A: Yes. Both parts are electrically and mechanically identical. The packaging format difference (Cut Tape versus Tape & Reel) does not affect component performance. Substitution is valid when assembly equipment can accommodate the alternate packaging format.

Q: Are the electrical specifications identical between S1KL RUG and S1KL?

A: Yes. Both parts share identical specifications for reverse voltage (800 V), forward current (1 A), forward voltage drop (1.1 V @ 1 A), reverse recovery time (1.8 µs), reverse leakage current (5 µA @ 800 V), and junction capacitance (9 pF @ 4V, 1MHz).

Q: Do both parts meet the same compliance standards?

A: Yes. Both S1KL RUG and S1KL carry ROHS3 compliance, REACH unaffected status, and MSL 1 (unlimited) moisture sensitivity rating. Compliance certifications are identical.

Q: What is the operating temperature range for both parts?

A: Both parts operate across a junction temperature range of -55°C to 175°C. Thermal performance and derating characteristics are identical.

Q: Is the DO-219AB package identical for both parts?

A: Yes. Both parts use the DO-219AB package in Sub SMA form factor. Package dimensions, pin configuration, and surface mount compatibility are identical.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, suitable for automated pick-and-place assembly. Cut Tape (CT) packaging supplies components on cut segments of carrier tape, suitable for manual handling or alternative assembly processes. Electrical and mechanical specifications remain unchanged.

Q: Can inventory availability influence the choice between these parts?

A: Yes. The S1KL (Cut Tape) shows 30,100 pieces in stock, while S1KL RUG (Tape & Reel) shows 943 pieces in stock. Availability may influence procurement decisions when both parts are electrically and mechanically equivalent.

Q: Are there any thermal or performance differences between these parts?

A: No. Both parts maintain identical thermal operating range (-55°C to 175°C), reverse recovery time (1.8 µs), and all other electrical characteristics. Performance is equivalent across all specified parameters.
