DMMT3906-TP Equivalent & Substitute Parts

Part Overview

The DMMT3906-TP is an active-status dual matched pair PNP bipolar junction transistor array manufactured by Micro Commercial Co. This surface mount component operates at maximum collector current of 200mA with a 40V collector-emitter breakdown voltage rating. The device is packaged in a 6-pin SOT-363 (SC-88, 6-TSSOP) configuration suitable for high-density circuit applications requiring matched transistor pairs.

Substitute parts are identified when equivalent electrical specifications, mechanical packaging, and compliance certifications align with the original component, enabling direct replacement in production and repair scenarios.

Engineering Selection Recommendations

The DMMT3906W-7-F is a direct electrical and mechanical substitute for the DMMT3906-TP. Both components are active-status products with identical electrical specifications across all critical parameters including collector current, breakdown voltage, saturation characteristics, current gain, power rating, and transition frequency.

Both parts maintain identical packaging in SOT-363 configuration, surface mount mounting type, and compliance certifications (ROHS3, REACH Unaffected). Moisture sensitivity levels are equivalent at MSL 1 (Unlimited).

The DMMT3906W-7-F provides an extended operating temperature range at the lower end (-65°C versus -55°C minimum), which represents an operational advantage in applications requiring enhanced low-temperature performance. This extended range does not restrict substitution in applications designed for the DMMT3906-TP.

Frequently Asked Questions (FAQ)

Q: Can the DMMT3906W-7-F replace the DMMT3906-TP in existing designs?

A: Yes. The DMMT3906W-7-F meets all electrical and mechanical specifications of the DMMT3906-TP. Pin configuration, package type (SOT-363), and electrical performance are identical, enabling direct substitution without circuit modification.

Q: Are there differences in operating temperature ranges?

A: The DMMT3906W-7-F operates from -65°C to 150°C, while the DMMT3906-TP operates from -55°C to 150°C. The substitute part extends the lower temperature limit by 10°C. Applications designed for the DMMT3906-TP operate within the DMMT3906W-7-F temperature range.

Q: Do both parts have identical RoHS and REACH compliance?

A: Yes. Both the DMMT3906-TP and DMMT3906W-7-F are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements.

Q: Is the SOT-363 package identical between both parts?

A: Yes. Both components use the 6-pin SOT-363 package (also designated 6-TSSOP or SC-88). Pin assignments, lead spacing, and mechanical dimensions are identical.

Q: What is the significance of the matched pair configuration?

A: Both parts are dual matched pair PNP transistor arrays, meaning two transistors are integrated on a single die with closely matched electrical characteristics. This configuration is essential for applications requiring balanced differential amplification or precision analog circuits.

Q: Are moisture sensitivity levels equivalent?

A: Yes. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.
