MAC15SDG Equivalent & Substitute Parts

Part Overview

The MAC15SDG is a logic-sensitive gate TRIAC manufactured by onsemi, rated for 400 V off-state voltage and 15 A on-state current in a Through Hole TO-220 package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The MAC15SDG serves applications requiring AC switching and phase control in industrial and consumer equipment operating within its specified voltage and current ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAC15SDG is determined by the following critical parameters:

• Triac Type: Logic - Sensitive Gate configuration must be maintained
• Voltage - Off State: Substitute must equal or exceed 400 V
• Current - On State (It (RMS)): Substitute must equal or exceed 15 A
• Voltage - Gate Trigger (Vgt): Must not exceed 1.5 V for gate drive compatibility
• Current - Gate Trigger (Igt): Must not exceed 5 mA for control circuit compatibility
• Package / Case: TO-220-3 form factor required for mechanical fit
• Mounting Type: Through Hole configuration required

The BTA316-600D,127 meets these substitution criteria with higher voltage and current ratings, providing design margin while maintaining gate trigger specifications and package compatibility.

Parameter Comparison

Engineering Selection Recommendations

The BTA316-600D,127 is an active product with RoHS compliance certification, providing regulatory advantage over the obsolete MAC15SDG. The substitute maintains identical gate trigger voltage and current specifications, ensuring direct compatibility with existing gate drive circuits. The higher off-state voltage rating (600 V vs. 400 V) and increased on-state current capacity (16 A vs. 15 A) provide design margin without requiring circuit modification. The elevated maximum junction temperature (125°C vs. 110°C) supports extended thermal operating range. Both components share identical TO-220-3 package geometry and Through Hole mounting configuration, permitting direct mechanical substitution on existing PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can the BTA316-600D,127 directly replace the MAC15SDG in existing designs?

A: Yes. Both components share identical gate trigger specifications (Vgt 1.5 V max, Igt 5 mA max), matching package geometry (TO-220-3), and Through Hole mounting configuration. The substitute's higher voltage and current ratings do not require circuit redesign.

Q: What is the significance of the higher 600 V off-state voltage rating on the BTA316-600D,127?

A: The 600 V rating provides additional voltage margin in applications originally designed for 400 V operation. This does not affect circuit function but increases component reliability in transient overvoltage conditions.

Q: Are there package differences between the MAC15SDG and BTA316-600D,127?

A: Both components use TO-220-3 package configuration. The BTA316-600D,127 is supplied in Tube packaging format, while the MAC15SDG packaging format is not specified. PCB footprint and lead spacing are identical.

Q: Does the BTA316-600D,127 require different gate drive circuitry?

A: No. Gate trigger specifications are identical (Vgt 1.5 V max, Igt 5 mA max), permitting use of existing gate drive circuits without modification.

Q: What compliance advantage does the BTA316-600D,127 offer?

A: The BTA316-600D,127 is RoHS Compliant and carries active product status, providing regulatory support for new designs and long-term availability assurance compared to the obsolete MAC15SDG.
