Equivalent & Substitute Parts Reference: S1BL M2G

Part Overview

The S1BL M2G (Manufacturer Part Number: S1BL M2G, Taiwan Semiconductor Corporation) is a general-purpose surface mount diode used for rectification applications. This device is specified for a reverse voltage of 100 V and an average rectified current of 1 A, housed in a DO-219AB (Sub SMA) package. The part is currently listed as "Active." In situations requiring alternative sourcing or design modification, parametric or mechanical equivalence must be maintained through verified substitutes with equivalent electrical ratings and package compatibilities.

Substitute Part Grouping Explanation

Substitute part selection for diodes in the rectifier category is determined by matching the following key electrical and mechanical parameters:

Maximum Reverse Voltage (Vr)
Average Rectified Current (Io)
Forward Voltage (Vf) at specified current
Reverse Recovery Time (trr)
Reverse Leakage Current at Vr
Mounting Type and Package/Case
Compliance (RoHS, REACH) Substitution is approved only where these parameters are identical or within accepted engineering tolerances for the application envelope.

Engineering Selection Recommendations

S1BL M2G and S1BL both provide an identical electrical specification and RoHS3/REACH compliance. S1BL is listed as "Not For New Designs," making S1BL M2G preferable for ongoing applications requiring an active product status. VS-2EFH01HM3/I exceeds the minimum current specification and offers equivalent voltage rating, package compatibility, and compliance, with an active product status.

Frequently Asked Questions (FAQ)

Q1: What electrical parameters must match for substituting S1BL M2G in rectifier applications?
Allowed substitutes must have the same or higher maximum reverse voltage, equivalent or higher average forward current, comparable forward voltage at specified current, reverse recovery time, and reverse leakage current.

Q2: Are package differences acceptable in this substitution group?
Substitution is permitted only for diodes in the DO-219AB (Sub SMA) package or those explicitly listed with compatible surface mount mechanical formats.

Q3: Is compliance (RoHS, REACH) mandatory when selecting substitute diodes?
RoHS3 and REACH compliance is mandatory for all substitutes, enforced by the input parameter list.

Q4: How should product status influence selection between S1BL M2G, S1BL, and VS-2EFH01HM3/I?
Active status components are preferred for production. Parts not for new designs may be used for service or repair only.

Q5: Can higher-rated parts like VS-2EFH01HM3/I be substituted based solely on provided data?
Substitution is allowed as all electrical and package parameters meet or exceed those specified for S1BL M2G. VS-2EFH01HM3/I maintains compliance and active product status.
