MAC97A6RLRPG Equivalent & Substitute Parts

Part Overview

The MAC97A6RLRPG is a logic-sensitive gate TRIAC manufactured by onsemi, rated for 400 V off-state voltage and 600 mA on-state current in a TO-92 through-hole package. The product is obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. Substitute parts are selected based on matching or exceeding electrical performance within the same package configuration.

Substitute Part Grouping Explanation

Substitute parts are organized into two categories based on electrical compatibility:

Direct Substitutes maintain the same voltage rating (400 V) and current rating (600 mA) with identical gate trigger characteristics, ensuring pin-for-pin compatibility and functional equivalence.

Similar Substitutes provide higher current capability (1 A) at the same voltage rating (400 V), suitable for applications requiring increased current headroom while maintaining the same package and gate sensitivity characteristics.

Substitution is determined by the following key parameters:

Voltage - Off State (must be ≥ 400 V)
Current - On State (must be ≥ 600 mA)
Voltage - Gate Trigger (must be ≤ 2 V)
Current - Gate Trigger (must be ≤ 5 mA)
Current - Hold (must be ≤ 10 mA)
Package / Case (TO-92-3 or TO-226-3)
Mounting Type (Through Hole)

Engineering Selection Recommendations

Direct Substitute - Preferred for Pin-for-Pin Replacement:

MAC97A8/DG,116 (WeEn Semiconductors) is the optimal direct substitute. It maintains identical electrical specifications to the MAC97A6RLRPG (400 V, 600 mA, 2 V gate trigger) with extended operating temperature range (-40°C to 125°C versus -40°C to 110°C). The part is active and RoHS compliant, with MSL 1 rating. Tape & Reel packaging supports automated assembly.

Alternative Direct Substitute:

MAC97A8,116 (NXP USA Inc.) provides direct electrical compatibility with 600 V off-state voltage rating, exceeding the 400 V requirement. Operating temperature extends to 125°C. The part is active and available in bulk packaging.

Higher Current Alternative - For Increased Current Margin:

Littelfuse L0107DE, L0107DEAP, and L0107DERP provide 1 A on-state current (versus 600 mA), offering 67% additional current capacity at the same 400 V voltage rating. Gate trigger voltage is lower (1.3 V versus 2 V), and gate trigger current matches the original specification (5 mA). All variants are active, RoHS3 compliant, and support -40°C to 125°C operation. Packaging options include bulk (DE), tape & box (DEAP), and tape & reel (DERP).

All recommended substitutes are active products with current manufacturing support and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can MAC97A8,116 replace MAC97A6RLRPG directly?

A: Yes. MAC97A8,116 maintains identical gate trigger characteristics (2 V, 5 mA) and on-state current (600 mA). The 600 V off-state voltage rating exceeds the 400 V requirement, providing additional voltage margin. Operating temperature range extends to 125°C. Pin configuration and TO-92-3 package are compatible.

Q: What is the difference between MAC97A8,116 and MAC97A8/DG,116?

A: Both parts have identical electrical specifications. MAC97A8,116 is supplied by NXP USA Inc. in bulk packaging. MAC97A8/DG,116 is supplied by WeEn Semiconductors in tape & reel packaging. Selection depends on packaging requirements for assembly processes.

Q: Why do Littelfuse L0107 variants have lower gate trigger voltage (1.3 V)?

A: The L0107 series maintains the same gate trigger current (5 mA) and hold current (10 mA) as the original part, with lower gate trigger voltage. This represents improved gate sensitivity and is compatible with the same gate drive circuits. The 1 A on-state current provides additional current capacity.

Q: Are there differences between L0103DE, L0103DEAP, and L0103DERP?

A: Electrical specifications are identical across all three variants. Packaging differs: DE is bulk, DEAP is tape & box, and DERP is tape & reel. Selection depends on assembly method and inventory management requirements.

Q: Can I use L0109DE instead of L0107DE?

A: Both parts have identical voltage and current ratings (400 V, 1 A). The difference is gate trigger current: L0107 is 5 mA maximum, L0109 is 10 mA maximum. L0107 is suitable for circuits requiring lower gate drive current. L0109 accommodates higher gate drive current requirements.

Q: Is the MAC97A6RLRPG still available?

A: No. The MAC97A6RLRPG is obsolete. Active substitutes from NXP USA Inc., WeEn Semiconductors, and Littelfuse Inc. are available with current manufacturing support and compliance certifications.
