MAC15N TRIAC Equivalent & Substitute Parts

Part Overview

The MAC15N is a standard TRIAC thyristor rated for 800V off-state voltage and 15A on-state current, packaged in TO-220-3 through-hole configuration. Manufactured by onsemi, this component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system support and new design implementations. The MAC15N serves as a general-purpose AC switching device suitable for applications requiring medium-voltage, medium-current thyristor control.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAC15N is determined by electrical and mechanical parameter equivalence within the thyristor category. The critical parameters governing substitutability are:

• Voltage - Off State: 800V minimum rating
• Current - On State: 15A RMS capability
• Gate trigger characteristics: Vgt ≤ 1.5V, Igt ≤ 35mA
• Hold current: Ih ≤ 40mA
• Package compatibility: TO-220-3 through-hole configuration
• Triac type: Standard configuration, single device

The MAC15NG from Littelfuse Inc. meets all electrical specifications and mechanical requirements, providing direct substitution capability. Both components share identical voltage, current, and thermal ratings, with compatible gate trigger and hold current parameters. The TO-220-3 package ensures mechanical and thermal interface compatibility.

For applications where the MAC15N is currently deployed, the MAC15NG provides pin-compatible, performance-equivalent substitution without circuit modification. The through-hole TO-220-3 package ensures identical thermal management and PCB integration.

Frequently Asked Questions (FAQ)

Q: Can MAC15NG replace MAC15N in existing designs? A: Yes. The MAC15NG is electrically and mechanically equivalent to the MAC15N. All voltage, current, gate trigger, and thermal parameters are identical. The TO-220-3 package provides direct pin compatibility.

Q: What is the primary reason to substitute MAC15N? A: The MAC15N is classified as obsolete. The MAC15NG provides equivalent performance with active product status and improved regulatory compliance (ROHS3).

Q: Are there package differences between MAC15N and MAC15NG? A: Both components use the TO-220-3 through-hole package. The MAC15NG is supplied in TO-220AB variant designation, which is mechanically and electrically compatible with the standard TO-220-3 specification.

Q: What are the critical parameters for TRIAC substitution? A: Off-state voltage rating, on-state RMS current capacity, gate trigger voltage and current, hold current, operating temperature range, and package type determine substitutability. All these parameters must match or exceed the original component specifications.

Q: Is the MAC15NG suitable for new product designs? A: Yes. The MAC15NG is an active product with ROHS3 compliance, making it appropriate for new designs requiring 800V, 15A TRIAC functionality in TO-220-3 configuration.
