MAC97A8RLRM TRIAC Equivalent & Substitute Parts
Part Overview
The MAC97A8RLRM is a logic-sensitive gate TRIAC manufactured by onsemi, rated for 600V off-state voltage with 600 mA on-state current in a TO-92 through-hole package. This component is classified as obsolete, making equivalent substitutes necessary for new designs and production continuity. Substitute parts must maintain compatibility across voltage rating, gate trigger characteristics, and thermal operating range while accommodating modern active-status alternatives.

Substitute Part Grouping Explanation
Substitution eligibility is determined by the following criteria:
Mandatory Compatibility Parameters:
- Voltage - Off State: 600 V (exact match required)
- Triac Type: Logic - Sensitive Gate (exact match required)
- Configuration: Single (exact match required)
- Mounting Type: Through Hole (exact match required)
- Package / Case: TO-92 or TO-92-3 variants (mechanical compatibility)
Allowable Variation Parameters:
- Current - On State (It RMS) Max: 600 mA or higher (upward compatibility)
- Voltage - Gate Trigger (Vgt) Max: 2 V or lower (tighter gate sensitivity acceptable)
- Current - Gate Trigger (Igt) Max: 5 mA or lower (lower trigger current acceptable)
- Current - Hold (Ih) Max: 10 mA or lower (lower hold current acceptable)
- Operating Temperature: Range must encompass or exceed -40°C to 110°C minimum
Substitute parts meeting these criteria are grouped by current rating and gate trigger voltage characteristics.

Engineering Selection Recommendations
Direct Current-Matched Substitutes (600–800 mA Range): BTA2008-600D,412 and Z00607MA variants (1BA2, 2BL2, 5BL2) provide the closest electrical match to the MAC97A8RLRM. These parts maintain 600–800 mA on-state current ratings and are all active-status products with modern RoHS compliance. The Z00607MA series offers tighter gate trigger voltage (1.3 V vs. 2 V) and lower hold current (5 mA vs. 10 mA), improving gate sensitivity and reducing parasitic triggering risk. BTA2008-600D,412 maintains the original 2 V gate trigger specification while offering 800 mA capacity and extended temperature range to 125°C.
Higher Current Capacity Substitutes (1 A Range): Z0103MA and Z0107MA series parts (from STMicroelectronics, WeEn Semiconductors, and NXP USA Inc.) provide 1 A on-state current, offering 67% higher current capacity than the original part. Z0107MA variants preserve the original 10 mA hold current specification, while Z0103MA variants reduce hold current to 7 mA. All variants feature 1.3 V gate trigger voltage and extended temperature range to 125°C. These parts are suitable for applications requiring higher current margin or thermal headroom.
Compliance Considerations: All substitute parts listed are active-status products. STMicroelectronics and WeEn Semiconductors variants carry ROHS3 compliance certification. NXP USA Inc. Z0103MA,412 does not specify RoHS status in provided data. Selection should prioritize ROHS3-compliant variants for new designs subject to environmental regulations.
Frequently Asked Questions (FAQ)
Q: Can I use a substitute part with higher on-state current (800 mA or 1 A) in place of the 600 mA MAC97A8RLRM?
A: Yes. Higher on-state current ratings provide upward compatibility. The substitute part will handle the same load current as the original while offering additional capacity margin. No circuit modification is required.
Q: What is the significance of gate trigger voltage (Vgt) differences between 2 V and 1.3 V?
A: Lower gate trigger voltage indicates higher gate sensitivity. Substitutes with 1.3 V Vgt (Z00607MA, Z0103MA, Z0107MA series) require less gate current to trigger the TRIAC. This improves noise immunity and reduces gate drive circuit complexity. Both specifications are compatible with standard gate drive circuits.
Q: Are the different packaging codes (2AL2, 5AL2, 2BL2, 5BL2) mechanically interchangeable?
A: Yes. All variants use TO-92-3 or TO-226-3 through-hole packages with identical lead spacing and mechanical footprint. Packaging codes indicate manufacturing date codes and tape/reel configurations, not physical dimensions. All are directly pin-compatible.
Q: The MAC97A8RLRM is obsolete. Which substitute should I select for a new design?
A: For new designs, select from active-status parts with ROHS3 compliance: Z00607MA series (800 mA, closest electrical match) or Z0107MA series (1 A, extended temperature range). Both offer modern compliance and long-term availability. Z0107MA 5AL2 is recommended for maximum inventory availability (2300 pcs in stock).
Q: Can I use Z0103MA or Z0107MA parts if my circuit is designed for 600 mA operation?
A: Yes. These 1 A parts are fully backward-compatible. The higher current rating does not affect circuit operation at 600 mA load current. The TRIAC will operate identically to the original part under the same gate drive and load conditions.
Q: What is the temperature operating range difference, and does it matter?
A: The MAC97A8RLRM operates -40°C to 110°C. Most substitutes extend to 125°C. This provides additional thermal margin in high-temperature environments but does not restrict use in applications within the original -40°C to 110°C range. Extended range is beneficial for industrial and automotive applications.
