SS12L MQG Equivalent & Substitute Parts Reference

Part Overview

The SS12L MQG is a 20V, 1A Schottky diode in a surface mount Sub SMA (DO-219AB) package, manufactured by Taiwan Semiconductor Corporation. Its product status is "Active." This diode provides fast recovery (≤500ns, >200mA Io), low forward voltage (450 mV @ 1A), and moderate reverse leakage (400 µA @ 20V). Alternative models are necessary for inventory management, supply continuity, or replacing discontinued, obsolete, or restricted parts in designs. For active products, substitutes might be needed for procurement flexibility or packaging preferences.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SS12L MQG are strictly selected according to the following key parameters: reverse voltage (20V max), rectified current (1A max), forward voltage drop (450 mV @ 1A), recovery speed (≤500ns, >200mA Io), reverse leakage (400 µA @ 20V), technology (Schottky), mounting type (Surface Mount), package/case (DO-219AB/Sub SMA), operating temperature (-55°C ~ 125°C), RoHS and REACH compliance, and moisture sensitivity level. Only parts matching these exact points qualify as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Selection must consider product status and compliance requirements. The SS12L MQG is "Active" and compliant with ROHS3 and REACH, with an unlimited moisture sensitivity level (MSL 1). The substitute SS12L meets identical compliance and environmental requirements but is "Not For New Designs." Substituting with SS12L should be reserved for maintenance or legacy use where the product's status is acceptable. For new designs or long-term sourcing, prioritize "Active" and fully compliant components.

Frequently Asked Questions (FAQ)

Q1: What defines a direct substitute for SS12L MQG in the diodes, rectifiers category?
A1: Only parts matching voltage, current, forward voltage drop, speed, reverse leakage, technology, mounting type, package/case, operating temperature, and compliance status.

Q2: Is packaging (Tape & Reel vs. standard) relevant for substitute selection?
A2: Packaging affects assembly and supply-chain logistics but does not alter electrical or mechanical substitutability when parametric specifications match.

Q3: Can SS12L be used in place of SS12L MQG for new designs?
A3: SS12L has a product status of "Not For New Designs;" its use is justified only in existing designs or maintenance scenarios given matching key parameters.

Q4: Are there environmental or compliance differences between SS12L MQG and SS12L?
A4: Both are ROHS3 compliant, REACH unaffected, and rated MSL 1 (unlimited).

Q5: Is package compatibility guaranteed between SS12L MQG and SS12L?
A5: Both are specified as DO-219AB Sub SMA surface-mount packages, ensuring direct mechanical compatibility.
