MAC97A6RL1 Equivalent & Substitute Parts

Part Overview

The MAC97A6RL1 is a Logic-Sensitive Gate TRIAC rated for 400V off-state voltage with 600mA on-state current in a Through Hole TO-92 package. Manufactured by onsemi, this component is classified as Obsolete. Due to its obsolete status and limited availability, identifying equivalent and substitute parts is necessary for design continuity and procurement planning.

Substitute Part Grouping Explanation

Substitution eligibility for the MAC97A6RL1 is determined by the following critical parameters:

Triac Type: Must be Logic - Sensitive Gate configuration
Voltage - Off State: Must be 400V or higher
Current - On State (It (RMS)): Must support minimum 600mA
Voltage - Gate Trigger (Vgt): Must not exceed 2V maximum
Current - Gate Trigger (Igt): Must not exceed 5mA maximum
Current - Hold (Ih): Must not exceed 10mA maximum
Mounting Type: Must be Through Hole
Package / Case: Must be TO-92-3 or TO-226-3 compatible

Substitute parts are categorized as Direct (pin-compatible, identical electrical ratings), Upgrade (enhanced performance, backward compatible), or Similar (compatible within specified parameter ranges).

Engineering Selection Recommendations

Direct Substitutes (Identical Electrical Ratings):

MAC97A8/DG,116 (WeEn Semiconductors): Matches all critical electrical parameters. Active product status. RoHS Compliant. Supplied in Tape & Reel packaging. Maximum operating temperature 125°C.
MAC97A8/DG,412 (NXP USA Inc.): Matches all critical electrical parameters. Active product status. Supplied in Bulk packaging. Maximum operating temperature 125°C.

Upgrade Substitute (Enhanced Current Capability):

LX807DE (Littelfuse Inc.): Supports 800mA on-state current versus 600mA, providing 33% higher current capacity. Lower gate trigger voltage (1.3V vs 2V) and lower hold current (5mA vs 10mA). Active product status. ROHS3 Compliant. Suitable for applications requiring higher current margins.

Similar Substitute (Minor Parameter Variation):

MAC97A6,116 (WeEn Semiconductors): Matches primary electrical parameters with gate trigger current of 7mA (versus 5mA maximum). Active product status. RoHS Compliant. Supplied in Cut Tape packaging.

Frequently Asked Questions (FAQ)

Q: Can LX807DE replace MAC97A6RL1 in all applications? LX807DE is electrically compatible as a direct substitute. The higher on-state current rating (800mA vs 600mA) provides additional design margin. Lower gate trigger voltage and hold current may improve circuit performance in sensitive gate applications. Verify circuit design does not depend on the original 600mA current limit.

Q: What is the difference between MAC97A8/DG,116 and MAC97A8/DG,412? Both parts have identical electrical specifications and match the MAC97A6RL1 ratings. The primary difference is packaging: MAC97A8/DG,116 is supplied in Tape & Reel format, while MAC97A8/DG,412 is supplied in Bulk format. Select based on procurement and assembly requirements.

Q: Is MAC97A6,116 suitable as a replacement? MAC97A6,116 is compatible with a minor parameter variation: gate trigger current is specified at 7mA maximum versus 5mA for the original part. This difference is within typical application tolerances for sensitive gate TRIACs. Verify circuit design does not require the lower gate trigger current specification.

Q: Why is RoHS compliance important for this substitution? The original MAC97A6RL1 is RoHS non-compliant. All active substitute options (LX807DE, MAC97A8/DG,116, MAC97A8/DG,412, MAC97A6,116) are RoHS Compliant or ROHS3 Compliant, meeting current environmental and regulatory requirements for new designs and procurement.

Q: Are all substitutes available in TO-92 package? All substitute parts are available in TO-92-3 or TO-226-3 packages, which are mechanically and electrically compatible with the original TO-92-3 package of the MAC97A6RL1.
