MAC4DSM-1G Equivalent & Substitute Parts

Part Overview

The MAC4DSM-1G is a Logic - Sensitive Gate TRIAC manufactured by Littelfuse, rated for 600 V off-state voltage and 4 A on-state current in a Surface Mount TO-252 (DPAK) package. This component is Active status and RoHS3 compliant. Equivalent and substitute parts are identified when design requirements permit changes in mounting type, current rating, or gate trigger characteristics while maintaining core electrical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the MAC4DSM-1G is based on the following allowed parameters:

Core Electrical Compatibility (Required Match):

• Voltage - Off State: 600 V
• Triac Type: Logic - Sensitive Gate or Alternistor - Snubberless
• Configuration: Single

Flexible Parameters (Substitution Permitted):

• Current - On State (It (RMS)): Equal or greater than 4 A
• Voltage - Gate Trigger (Vgt): Maximum 1.3 V
• Current - Gate Trigger (Igt): Maximum 10 mA
• Current - Hold (Ih): Maximum 15 mA
• Mounting Type: Surface Mount or Through Hole
• Package / Case: TO-252 (DPAK) or TO-251 (IPAK/V-Pak)
• Operating Temperature: -40°C minimum, 125°C maximum

Substitutes are grouped by current rating and mounting type. Parts with higher current ratings (6 A, 8 A) are suitable when circuit design permits increased current capacity. Through-hole alternatives are available for applications requiring different assembly methods.

Parameter Comparison

Engineering Selection Recommendations

Surface Mount DPAK Package (Direct Mounting Compatibility):

• T410-600B (STMicroelectronics): Maintains Surface Mount TO-252 DPAK package with identical 4 A current rating and 600 V voltage specification. Operating temperature range extends to 125°C, matching the MAC4DSM-1G. All electrical parameters align within specification limits. RoHS3 compliant and Active status.

Through Hole TO-251 Package (Assembly Method Alternative):

• L6004V3TP (Littelfuse Inc.): 4 A current rating, 600 V voltage, Logic - Sensitive Gate type. Gate trigger current reduced to 3 mA maximum. Operating temperature limited to 110°C. RoHS3 compliant and Active status.
• L6004V5TP (Littelfuse Inc.): 4 A current rating, 600 V voltage, Logic - Sensitive Gate type. Gate trigger current 5 mA maximum. Operating temperature limited to 110°C. RoHS3 compliant and Active status.

Higher Current Rating (Increased Capacity):

• L6006V6TP (Littelfuse Inc.): 6 A current rating, 600 V voltage, Logic - Sensitive Gate type. Through Hole TO-251 package. Operating temperature limited to 110°C. RoHS3 compliant and Active status.
• L6008V8TP (Littelfuse Inc.): 8 A current rating, 600 V voltage, Logic - Sensitive Gate type. Through Hole TO-251 package. Operating temperature limited to 110°C. RoHS3 compliant and Active status.

Alternative Triac Type (Snubberless Technology):

• T435-600H (STMicroelectronics): Alternistor - Snubberless type, 4 A current rating, 600 V voltage. Through Hole TO-251 IPAK package. Gate trigger current 35 mA maximum and hold current 35 mA maximum. Operating temperature extends to 125°C. RoHS3 compliant and Active status. Note: Higher gate trigger and hold currents require circuit design verification.

All substitute parts maintain RoHS3 compliance and Active product status. Selection depends on assembly method requirements (Surface Mount vs. Through Hole), current capacity needs, and operating temperature constraints.

Frequently Asked Questions (FAQ)

Q: Can L6004V3TP replace MAC4DSM-1G in a Surface Mount application? A: L6004V3TP is a Through Hole TO-251 package component and cannot directly replace a Surface Mount TO-252 DPAK package. Assembly method compatibility must be verified. For Surface Mount applications, T410-600B maintains the DPAK package format.

Q: What is the difference between Logic - Sensitive Gate and Alternistor - Snubberless types? A: Both are TRIAC types rated for 600 V and 4 A in the substitute list. T435-600H (Alternistor - Snubberless) has higher gate trigger current (35 mA maximum) and hold current (35 mA maximum) compared to Logic - Sensitive Gate types. Circuit design must accommodate these higher gate drive requirements.

Q: Can I use L6006V6TP (6 A) or L6008V8TP (8 A) in place of MAC4DSM-1G (4 A)? A: Yes, if circuit design permits higher current capacity. Both parts maintain 600 V voltage rating and Logic - Sensitive Gate type. Operating temperature is limited to 110°C compared to 125°C for the original part. Verify thermal management and current distribution in the application.

Q: What is the operating temperature difference between MAC4DSM-1G and substitute parts? A: MAC4DSM-1G and T410-600B support -40°C to 125°C. Littelfuse through-hole alternatives (L6004V3TP, L6004V5TP, L6006V6TP, L6008V8TP) are limited to -40°C to 110°C. T435-600H supports -40°C to 125°C. Verify application temperature requirements before selection.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All substitute parts listed are RoHS3 compliant and maintain Active product status, matching the compliance profile of MAC4DSM-1G.

Q: What does "Current - Non Rep. Surge" mean in the context of substitution? A: Current - Non Rep. Surge (Itsm) represents the maximum non-repetitive surge current the TRIAC can withstand. This parameter varies among substitutes but does not determine substitution eligibility. Core electrical ratings (voltage, on-state current, gate trigger voltage) determine compatibility.
