TMA164S-L Equivalent & Substitute Parts

Part Overview

The TMA164S-L is a standard TRIAC manufactured by Sanken Electric USA Inc., rated for 400V off-state voltage and 16A on-state current in a TO-220F package. This component is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The part operates across a temperature range of -40°C to 125°C and is RoHS compliant with MSL Level 1 rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TMA164S-L is determined by the following critical parameters:

• Voltage Rating (Off State): Substitute parts must meet or exceed 400V to ensure safe operation in the original circuit
• Current Rating (On State): Substitute parts must support minimum 16A RMS current capacity
• Gate Trigger Voltage (Vgt): Maximum 1.5V ensures compatible gate drive requirements
• Gate Trigger Current (Igt): Maximum 30mA defines gate control circuit compatibility
• Package Type: TO-220F or equivalent TO-220 configuration with isolated tab for mechanical and thermal compatibility
• Mounting Configuration: Through-hole mounting required for PCB integration

Two substitute parts meet these criteria with specific trade-offs in performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

BTA316X-600C,127 (NXP USA Inc.): This substitute maintains identical current and gate trigger voltage specifications to the TMA164S-L while providing elevated voltage rating at 600V. The part is active in production status with robust inventory availability. RoHS compliance is confirmed. The higher voltage rating provides additional safety margin in applications where transient overvoltages may occur. Gate trigger current specification increases to 35mA, requiring verification that gate drive circuits can accommodate this parameter shift.

Q4030LH5TP (Littelfuse Inc.): This substitute employs Alternistor snubberless technology with doubled current capacity at 30A on-state rating. The part is active in production with strong inventory levels and ROHS3 compliance. Surge current capability is significantly enhanced at 290A and 350A. Gate trigger voltage increases to 2V maximum and gate trigger current to 50mA, both exceeding original specifications. This option suits applications requiring higher current handling or snubberless operation benefits. Temperature range extends to -25°C minimum, narrower than the original -40°C specification.

Frequently Asked Questions (FAQ)

Q: Can BTA316X-600C,127 be used as a direct replacement for TMA164S-L?

A: Yes, within the specified electrical parameters. The 600V rating exceeds the 400V requirement, and current, gate trigger voltage, and package configurations are compatible. Gate trigger current increases from 30mA to 35mA; verify gate drive circuit capability.

Q: What is the primary difference between the two substitute options?

A: BTA316X-600C,127 maintains the standard TRIAC type with matched current rating, while Q4030LH5TP uses Alternistor snubberless technology with doubled current capacity. Q4030LH5TP provides higher surge current handling but requires gate drive circuits rated for 50mA trigger current.

Q: Are both substitutes RoHS compliant?

A: Yes. BTA316X-600C,127 is RoHS compliant, and Q4030LH5TP is ROHS3 compliant, both meeting environmental regulatory requirements.

Q: Does the Q4030LH5TP temperature range affect compatibility?

A: Q4030LH5TP operates from -25°C to 125°C, compared to the original -40°C to 125°C range. Applications requiring operation below -25°C require the BTA316X-600C,127 or continued use of TMA164S-L stock.

Q: What packaging considerations apply to these substitutes?

A: All three parts use TO-220 through-hole mounting. BTA316X-600C,127 and Q4030LH5TP feature isolated tabs, compatible with standard TO-220F footprints. Thermal management and PCB layout remain consistent across all options.

Q: Can Q4030LH5TP replace TMA164S-L in all applications?

A: Q4030LH5TP is suitable for applications tolerating the -25°C minimum temperature limit and gate drive circuits rated for 50mA trigger current. The snubberless design and higher current rating may provide performance benefits in specific applications but require circuit validation.
