Engineering Selection Recommendations

The CMLDM7003TG TR PBFREE is the direct substitute for the obsolete CMLDM7003T TR. Selection of this alternative is based on the following engineering criteria:

Product Status: The CMLDM7003T TR is classified as obsolete, creating supply chain risk. The CMLDM7003TG TR PBFREE maintains active product status with significantly higher inventory availability (10,455 pieces versus 1,772 pieces), ensuring long-term procurement viability.

Electrical Equivalence: All electrical parameters are identical across both parts, including voltage rating, current capacity, on-resistance, threshold voltage, gate charge, and input capacitance. No circuit redesign or performance adjustment is required.

Compliance and Certifications: Both parts maintain ROHS3 compliance and REACH unaffected status. The substitute incorporates lead-free (PBFREE) processing, which aligns with modern manufacturing standards and environmental regulations.

Packaging Compatibility: Both parts utilize SOT-563 and SOT-666 surface mount packages with identical pinout and footprint. The packaging format difference (Cut Tape versus Tape & Reel) does not affect electrical or mechanical compatibility; this distinction relates only to procurement and handling logistics.

Moisture Sensitivity: Both parts carry MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can CMLDM7003TG TR PBFREE be used as a direct replacement for CMLDM7003T TR in existing designs?

A: Yes. All electrical parameters, mechanical specifications, and package dimensions are identical. No circuit modifications are required. The substitute operates within the same voltage, current, and temperature specifications.

Q: What is the difference between the Cut Tape and Tape & Reel packaging formats?

A: Cut Tape (CT) and Tape & Reel (TR) are packaging and delivery formats that do not affect component electrical or mechanical properties. Cut Tape is supplied in shorter lengths for smaller orders, while Tape & Reel is supplied on continuous reels for high-volume manufacturing. Both formats use identical component specifications and pinout.

Q: Why is the CMLDM7003T TR classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production. The CMLDM7003TG TR PBFREE is the active replacement, offering identical electrical performance with modern lead-free processing.

Q: Are there any thermal or performance differences between the two parts?

A: No. Both parts have identical maximum power dissipation (350mW), operating temperature range (-65°C to 150°C), and thermal characteristics. Performance in thermal management applications is equivalent.

Q: Does the lead-free (PBFREE) designation affect compatibility?

A: No. Lead-free processing is a manufacturing standard that does not alter electrical performance, mechanical fit, or functional compatibility. The PBFREE designation indicates compliance with RoHS regulations and modern environmental standards.

Q: What inventory considerations should be made when selecting between these parts?

A: The CMLDM7003TG TR PBFREE has significantly higher inventory availability (10,455 pieces) compared to the obsolete CMLDM7003T TR (1,772 pieces). For new designs and long-term production, the active substitute ensures supply chain continuity.

Q: Are the gate charge and input capacitance specifications identical?

A: Yes. Gate charge (Qg) is 0.76nC @ 4.5V and input capacitance (Ciss) is 50pF @ 25V for both parts. Switching speed and gate drive requirements are equivalent.
