Key Parameters

Substitute Part Grouping Explanation

Substitution of the TMB166S-L is determined by alignment across the following critical parameters:

• Voltage Rating: Off-state voltage must equal or exceed 600V
• Current Rating: On-state RMS current must meet or exceed 16A
• Gate Trigger Characteristics: Vgt and Igt parameters must remain within compatible ranges
• Surge Current Capability: Non-repetitive surge current ratings (50Hz/60Hz) must support system transient requirements
• Package Configuration: Through-hole TO-220-3 mounting compatibility
• Compliance & Certification: RoHS compliance and MSL rating must be maintained

The TMG16CQ60F5 qualifies as a manufacturer-recommended substitute based on matching voltage and current specifications within the Sanken Electric product family.

Parameter Comparison

Engineering Selection Recommendations

The TMG16CQ60F5 is designated as the manufacturer-recommended substitute for the obsolete TMB166S-L. Both components share identical voltage and current ratings (600V, 16A) and maintain equivalent compliance certifications. The TMG16CQ60F5 carries active product status, ensuring ongoing availability and manufacturing support.

Selection of the TMG16CQ60F5 is appropriate for applications requiring direct replacement of the TMB166S-L without circuit redesign. Both parts maintain RoHS compliance and MSL Level 1 rating, supporting identical storage and handling protocols. The active status of the substitute part provides supply chain continuity for production and field service applications.

Frequently Asked Questions (FAQ)

Q: Can the TMG16CQ60F5 directly replace the TMB166S-L in existing designs?

A: Yes. Both components share identical voltage (600V) and current (16A) specifications. The TMG16CQ60F5 is the manufacturer-recommended substitute and maintains equivalent compliance certifications.

Q: What is the primary reason for substitution?

A: The TMB166S-L is classified as obsolete. The TMG16CQ60F5 provides equivalent electrical performance with active product status and ongoing manufacturing support.

Q: Are there package compatibility considerations?

A: Both components use TO-220-3 Full Pack configuration suitable for through-hole mounting. Physical footprint compatibility is maintained.

Q: Do compliance and certification requirements remain the same?

A: Yes. Both parts are RoHS compliant with MSL Level 1 rating and identical ECCN and HTSUS classifications.

Q: What parameters must be verified for substitution in a specific application?

A: Confirm that your circuit operates within the specified voltage (600V off-state), current (16A on-state), and gate trigger ranges (Vgt 1.5V max, Igt 30mA max). Verify that non-repetitive surge current requirements (160A/168A at 50/60Hz) align with system transient specifications.
