TMA106S-L Equivalent & Substitute Parts

Part Overview

The TMA106S-L is a standard TRIAC manufactured by Sanken Electric USA Inc., rated for 600V off-state voltage and 10A on-state current in a TO-220-3 Full Pack configuration. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The part is RoHS compliant and suitable for applications requiring through-hole thyristor switching in the 600V/10A range.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TMA106S-L are evaluated based on the following critical parameters that determine functional compatibility:

Voltage Rating (Off-State): The substitute must maintain the 600V off-state voltage specification to ensure safe operation in the original circuit design.

Current Rating (On-State): The substitute current rating must be equal to or greater than the original 10A specification to handle the same load conditions.

Gate Trigger Characteristics: Voltage (Vgt) and current (Igt) parameters must be compatible with existing gate drive circuitry.

Package and Mounting: Through-hole TO-220 variants are acceptable provided pin configuration remains compatible.

Triac Type: Standard TRIAC types are directly substitutable; Alternistor (snubberless) types represent a functional variant with different gate characteristics.

Product Status and Compliance: Active status parts with RoHS compliance ensure long-term availability and regulatory conformance.

Based on these criteria, the substitute parts are grouped as follows:

Group 1 - Manufacturer Recommended (Higher Voltage Rating): TMG10C80F5 from Sanken Electric USA Inc. offers 800V rating with 10A current, providing enhanced voltage margin while maintaining current capacity.

Group 2 - Voltage-Compatible Substitutes (600V Rating): Q6006L5TP (Littelfuse Inc., 6A) and T435T-600FP (STMicroelectronics, 4A) maintain the 600V voltage specification but with reduced current ratings.

Parameter Comparison

Engineering Selection Recommendations

TMG10C80F5 (Manufacturer Recommended): This Sanken Electric part maintains 10A current capacity with elevated 800V off-state voltage. As an active product from the original manufacturer with RoHS compliance, it provides the most direct upgrade path. The higher voltage rating offers additional design margin without circuit modification requirements.

Q6006L5TP (Littelfuse Inc.): This active ROHS3-compliant part maintains 600V voltage compatibility but reduces current capacity to 6A. Selection requires verification that circuit load does not exceed 6A on-state current. The isolated tab package variant differs from the full pack configuration of the original part. Gate trigger current requirement increases to 50 mA.

T435T-600FP (STMicroelectronics): This active ROHS3-compliant Alternistor variant maintains 600V voltage but reduces current capacity to 4A. The snubberless design alters gate trigger characteristics (1.3V Vgt, 35 mA Igt). Selection requires confirmation that circuit load does not exceed 4A and that gate drive circuitry is compatible with snubberless operation. Package configuration matches the original TO-220-3 Full Pack.

Frequently Asked Questions (FAQ)

Q: Can TMG10C80F5 be used as a direct replacement for TMA106S-L?

A: Yes. TMG10C80F5 maintains the 10A current rating and exceeds the 600V voltage specification at 800V. No circuit modifications are required. Both parts are from Sanken Electric USA Inc. and are RoHS compliant.

Q: What is the primary limitation of Q6006L5TP as a substitute?

A: Q6006L5TP reduces on-state current capacity from 10A to 6A. This part is suitable only for applications where circuit load current does not exceed 6A. Additionally, the isolated tab package differs from the original full pack configuration.

Q: Why does T435T-600FP have different gate trigger specifications?

A: T435T-600FP is an Alternistor (snubberless) TRIAC type, which operates with different gate characteristics than standard TRIACs. Gate trigger voltage is lower (1.3V vs. 1.5V) but gate trigger current is higher (35 mA vs. 30 mA). Existing gate drive circuitry must be verified for compatibility.

Q: What is the current capacity limitation of T435T-600FP?

A: T435T-600FP is rated for 4A on-state current, the lowest among substitute options. This part is suitable only for applications where circuit load current does not exceed 4A.

Q: Are all substitute parts RoHS compliant?

A: Yes. TMA106S-L is RoHS Compliant. TMG10C80F5 is RoHS Compliant. Q6006L5TP and T435T-600FP are both ROHS3 Compliant, meeting current regulatory requirements.

Q: Can substitute parts be used interchangeably in the same circuit?

A: No. Each substitute has different current and voltage specifications. Selection must be based on specific circuit requirements. TMG10C80F5 is the most direct replacement. Q6006L5TP and T435T-600FP require load current verification before selection.
