Equivalent & Substitute Parts Reference for S1DL

Part Overview

The S1DL from Taiwan Semiconductor Corporation is a surface mount, standard recovery rectifier diode rated for 200 V and 1 A, supplied in SOD-123 (Sub SMA) packaging. Its technology is standard recovery with a reverse recovery time of 1.8 µs and a forward voltage of 1.1 V at 1 A. The S1DL is currently marked as "Not For New Designs," necessitating the identification of equivalent or substitute models for continued production or maintenance purposes.

Key Parameters

Substitute Part Grouping Explanation

Substitute and equivalent diode rectifier models for S1DL are identified strictly through reviewing the following allowed parameters: rated DC reverse voltage (Vr), average rectified current (Io), forward voltage (Vf), mounting type, package/case, operating temperature range, RoHS/REACH compliance, MSL, and regulatory codes. These diodes must be surface mount components within the Diodes, Rectifiers category, have a matched voltage and current rating, and comply with comparable environmental and packaging standards.

Engineering Selection Recommendations

Selection of a substitute for S1DL should be based on matching product status and required certifications. S1DL is "Not For New Designs," necessitating an active part for continuity. All listed substitutes (S1DLW, VS-1EFH02-M3/I, VS-2EFH02HM3/I) are active, ROHS3 compliant, REACH unaffected, and have an unlimited moisture sensitivity level (MSL 1). Each conforms to ECCN EAR99 and HTSUS 8541.10.0080. Only parameters provided should be used for direct matching.

Frequently Asked Questions (FAQ)

Q1: What qualifies a diode as a substitute for S1DL?
A: Substitute diodes must share matching voltage and current specifications, compliance certifications, mounting type, and similar package characteristics as listed for S1DL.

Q2: Does package difference affect compatibility?
A: Only listed package types (SOD-123, SOD-123W, DO-219AB) are compared. Package compatibility should be confirmed strictly with the provided package information.

Q3: Are all substitute parts suitable for immediate use in existing S1DL designs?
A: Suitability is determined strictly by matching the allowed and specified electrical and mechanical parameters, product status, and compliance certifications provided.

Q4: What certifications are required for substitute selection?
A: ROHS3 compliance, REACH unaffected status, MSL 1 (Unlimited), ECCN EAR99, and HTSUS 8541.10.0080 must be present as listed.

Q5: Are there differences in reverse recovery time or capacitance among substitutes?
A: Only the provided reverse recovery time and capacitance parameters should be compared for selection purposes. No further extrapolations should be made.

Q6: How should “Not For New Designs” status influence part selection?
A: "Not For New Designs" indicates discontinued or restricted availability; therefore, substitute parts with "Active" status should be selected as direct replacements.
