MAC97A8RLRP TRIAC Equivalent & Substitute Parts

Part Overview

The MAC97A8RLRP is a logic-sensitive gate TRIAC manufactured by onsemi, rated for 600 V off-state voltage and 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 electrical compatibility across gate trigger characteristics, voltage ratings, and thermal operating ranges while accommodating modern active-status alternatives.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Primary Compatibility Requirements:

Voltage - Off State: 600 V (exact match required)
Package / Case: TO-226-3 or TO-92-3 (mechanical and pin compatibility)
Mounting Type: Through Hole (assembly compatibility)
Triac Type: Logic - Sensitive Gate (functional equivalence)

Secondary Compatibility Parameters:

Current - On State (It RMS) Max: 600 mA minimum (equal or higher acceptable)
Voltage - Gate Trigger (Vgt) Max: 2 V maximum (equal or lower acceptable)
Current - Gate Trigger (Igt) Max: 5 mA maximum (equal or lower acceptable)
Current - Hold (Ih) Max: 10 mA maximum (equal or lower acceptable)

Substitute parts with higher current ratings or lower gate trigger thresholds provide enhanced performance margins. Parts with identical or superior gate sensitivity characteristics maintain or improve circuit reliability.

Engineering Selection Recommendations

Direct Substitutes (Minimal Design Impact):

BTA2008-600D,412 and Z00607MA variants provide the closest electrical match to MAC97A8RLRP. These parts maintain 600 V off-state voltage, support 800 mA on-state current (33% margin above original 600 mA specification), and preserve gate trigger characteristics within acceptable tolerances. BTA2008-600D,412 is RoHS Compliant and active in production. Z00607MA variants are ROHS3 Compliant with extended temperature ranges to 110°C or 125°C.

Enhanced Performance Substitutes (Improved Margins):

Z0103MA and Z0107MA series offer 1 A on-state current capability with superior gate sensitivity (Vgt 1.3 V, Igt 3 mA for Z0103MA variants). These parts provide 67% current margin and lower gate trigger thresholds, improving circuit reliability. Z0103MA,126 offers the lowest gate trigger voltage (1 V) among active alternatives. All Z0103MA and Z0107MA variants are ROHS3 Compliant or RoHS Compliant with operating temperatures to 125°C.

Frequently Asked Questions (FAQ)

Q: Can Z0103MA series parts directly replace MAC97A8RLRP?

A: Yes. Z0103MA parts maintain 600 V off-state voltage and TO-92-3 package compatibility. The 1 A on-state current rating exceeds the original 600 mA specification, providing design margin. Gate trigger characteristics (Vgt 1.3 V, Igt 3 mA) are within acceptable substitution limits. All Z0103MA variants are active-status components with current production support.

Q: What is the difference between Z00607MA and Z0103MA substitutes?

A: Z00607MA provides 800 mA on-state current with lower gate trigger voltage (1.3 V) and reduced hold current (5 mA). Z0103MA provides 1000 mA on-state current with identical gate trigger voltage (1.3 V) but higher hold current (7 mA). Z0103MA offers greater current capacity; Z00607MA offers lower power dissipation in gate circuits. Both are electrically compatible with MAC97A8RLRP.

Q: Are packaging variants (TO-92 vs. TO-92-3) interchangeable?

A: TO-92 and TO-92-3 packages are mechanically compatible for through-hole mounting. Both use identical pin spacing and lead configurations. Z00607MA 2BL2 is specified as TO-92; all other substitutes are TO-92-3. Verify PCB footprint design accommodates either variant before selection.

Q: Which substitute offers the best RoHS compliance?

A: STMicroelectronics Z00607MA and Z0103MA variants are ROHS3 Compliant. WeEn Semiconductors BTA2008-600D,412 and Z0103MA,116 are RoHS Compliant. NXP USA Inc. Z0103MA,412 meets RoHS requirements. All listed substitutes satisfy modern environmental compliance standards.

Q: What is the temperature operating range difference?

A: MAC97A8RLRP operates -40°C to 110°C. BTA2008-600D,412 and most Z0103MA variants extend to 125°C, providing 15°C additional margin. Z00607MA variants maintain -40°C to 110°C range. Extended temperature capability improves reliability in thermal stress applications.

Q: Can I use BTA2008-600D,412 in existing MAC97A8RLRP designs without modification?

A: Yes. BTA2008-600D,412 maintains identical voltage rating (600 V), package (TO-92-3), and gate trigger characteristics (Vgt 2 V, Igt 5 mA). The 800 mA current rating provides 33% design margin above the original 600 mA specification. No circuit modifications are required for direct substitution.
