MAC97A6G Equivalent & Substitute Parts

Part Overview

The MAC97A6G is a Logic-Sensitive Gate TRIAC rated for 400V off-state voltage and 600mA on-state current in a Through Hole TO-92 package, manufactured by onsemi. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

TRIAC substitutes for the MAC97A6G must maintain compatibility across voltage ratings, current handling, gate trigger characteristics, and thermal operating ranges to ensure functional equivalence in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAC97A6G is determined by the following criteria:

Direct Substitutes maintain identical or superior electrical performance across all critical parameters: 400V off-state voltage, 600mA on-state current rating, gate trigger voltage and current specifications, and hold current characteristics. These parts are pin-compatible and require no circuit modifications.

Upgrade Substitutes provide enhanced performance or extended temperature ratings while maintaining the same voltage and current class. These parts are functionally compatible but may offer improved reliability or compliance status.

Similar Substitutes share the same TRIAC type classification and package form factor but may have variations in voltage rating, current capacity, or gate trigger characteristics. Selection requires verification that circuit design tolerances accommodate parameter differences.

The following parameters determine substitution validity:

• Voltage - Off State (must equal or exceed 400V)
• Current - On State rating (must equal or exceed 600mA)
• Gate Trigger Voltage (Vgt) and Current (Igt) compatibility
• Hold Current (Ih) specifications
• Package / Case compatibility (TO-92-3 or TO-226-3)
• Operating temperature range coverage

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Recommended for Replacement):

MAC97A8/DG,412 (NXP USA Inc.) and MAC97A6,412 (WeEn Semiconductors) are direct functional equivalents. Both maintain 400V voltage rating and 600mA current capacity with identical gate trigger and hold current specifications. Both are active products with ROHS3 compliance, providing long-term availability and regulatory alignment. MAC97A8/DG,412 offers extended temperature rating to 125°C, providing thermal margin over the original specification.

Upgrade Substitutes (Enhanced Performance):

LX807DE (Littelfuse Inc.) and Z00607MA 1BA2 (STMicroelectronics) provide higher on-state current capacity (800mA) and lower gate trigger voltage (1.3V), enabling more sensitive gate operation. LX807DE maintains the 400V voltage class, while Z00607MA 1BA2 provides 600V rating for applications requiring higher voltage margin. Both are active products with ROHS3 compliance.

Similar Substitutes (Conditional Selection):

MAC97A6,116 (WeEn Semiconductors) matches the 400V/600mA specification with RoHS compliance and active product status. Gate trigger voltage is reduced to 1.5V with slightly elevated gate trigger current (7mA), requiring circuit verification for gate drive compatibility.

Selection priority: Active product status and ROHS3 compliance are mandatory for new designs. Voltage and current ratings must meet or exceed application requirements. Gate trigger characteristics must align with available gate drive circuitry.

Frequently Asked Questions (FAQ)

Q: Can LX807DE replace MAC97A6G in all applications?

LX807DE is electrically compatible as a direct substitute. It maintains 400V voltage rating and exceeds the 600mA current requirement with 800mA capacity. Lower gate trigger voltage (1.3V vs. 2V) may require gate drive circuit verification to confirm adequate trigger margin. Package compatibility is confirmed (TO-92-3).

Q: What is the difference between MAC97A8/DG,412 and MAC97A6,412?

Both are functionally equivalent at 400V/600mA with identical gate trigger specifications. MAC97A8/DG,412 is manufactured by NXP USA Inc. with extended temperature rating to 125°C. MAC97A6,412 is manufactured by WeEn Semiconductors with temperature rating to 125°C. Both are active products with ROHS3 compliance. Selection may be based on supplier availability and procurement lead time.

Q: Why is Z00607MA 1BA2 listed as a similar substitute rather than direct substitute?

Z00607MA 1BA2 has 600V off-state voltage rating compared to MAC97A6G's 400V specification. While this provides higher voltage margin, it represents a different voltage class. Applications designed for 400V operation do not require 600V rating. Selection is appropriate only when circuit design accommodates or benefits from the higher voltage specification.

Q: Are all substitute parts available in the same packaging?

All listed substitutes use TO-92-3 or TO-226-3 package forms, maintaining pin compatibility with MAC97A6G. Packaging variants (Bulk, Cut Tape) affect procurement and handling but do not impact electrical or mechanical compatibility.

Q: What compliance certifications should I verify for new designs?

ROHS3 compliance is confirmed for LX807DE, MAC97A8/DG,412, MAC97A6,116, MAC97A6,412, and Z00607MA 1BA2. All parts carry REACH Unaffected status. ECCN classification is EAR99 for all parts. Verify compliance requirements with your procurement and regulatory teams for specific application markets.

Q: Can I use MAC97A6,116 if gate trigger voltage is lower than the original part?

MAC97A6,116 has 1.5V gate trigger voltage compared to MAC97A6G's 2V specification. Lower gate trigger voltage indicates more sensitive gate operation, requiring less gate drive current. Circuit verification is necessary to confirm that available gate drive voltage and current are adequate for reliable triggering across the operating temperature range.
