CMLDM7003 TR Equivalent & Substitute Parts

Part Overview

The CMLDM7003 TR is a dual N-channel MOSFET array manufactured by Central Semiconductor Corp, designed for surface mount applications in the SOT-563 package. This component features a 50V drain-to-source voltage rating with 280mA continuous drain current capability and 350mW maximum power dissipation. The part is classified as obsolete, necessitating identification of active equivalent alternatives for ongoing design support and procurement continuity. Substitute parts must maintain electrical and mechanical compatibility within the specified parameter tolerances.

Engineering Selection Recommendations

CMLDM7003G TR (Primary Substitute)

The CMLDM7003G TR is the manufacturer-recommended direct equivalent, produced by Central Semiconductor Corp as the active successor to the obsolete CMLDM7003 TR. This substitute maintains identical electrical specifications across all critical parameters: 50V Vdss, 280mA continuous drain current, 2Ohm Rds On, and 350mW power rating. The component shares the same SOT-563 package configuration and operating temperature range (-65°C to 150°C). The primary distinction is packaging format: CMLDM7003G TR is supplied in Tape & Reel (TR) configuration with higher inventory availability (5522 pcs) compared to the Cut Tape (CT) format of the original part. Full RoHS3 compliance and REACH Unaffected status are maintained. This substitute is suitable for direct replacement in all applications where the CMLDM7003 TR was originally specified.

EM6K33T2R (Secondary Substitute)

The EM6K33T2R, manufactured by Rohm Semiconductor, provides an alternative dual N-channel MOSFET array in SOT-563 package with 50V Vdss rating and active product status. This substitute features Logic Level Gate capability with 1.2V drive specification. Parameter deviations from the original part include: reduced continuous drain current (200mA versus 280mA), slightly elevated Rds On (2.2Ohm @ 200mA, 4.5V versus 2Ohm @ 50mA, 5V), and reduced maximum power dissipation (150mW versus 350mW). The operating temperature range specification is provided as 150°C maximum junction temperature without lower temperature limit documentation. Input capacitance is reduced to 25pF @ 10V. Gate charge specification is not provided. This substitute is applicable only in applications where the reduced current and power ratings are acceptable and where the lower operating temperature minimum is not a design constraint.

Frequently Asked Questions (FAQ)

Q: Can CMLDM7003G TR be used as a direct replacement for CMLDM7003 TR?

A: Yes. The CMLDM7003G TR is the manufacturer-recommended active equivalent with identical electrical specifications and package compatibility. The only difference is the packaging format (Tape & Reel versus Cut Tape), which does not affect component performance or board-level functionality.

Q: What are the key differences between CMLDM7003G TR and EM6K33T2R?

A: Both are dual N-channel MOSFETs in SOT-563 package with 50V Vdss rating. The CMLDM7003G TR maintains the original 280mA current and 350mW power rating. The EM6K33T2R has reduced specifications: 200mA continuous drain current and 150mW maximum power. The EM6K33T2R includes Logic Level Gate feature (1.2V drive) not present in the original part. Selection depends on application current and power requirements.

Q: Are both substitutes RoHS3 compliant?

A: Yes. Both CMLDM7003G TR and EM6K33T2R are ROHS3 Compliant with REACH Unaffected status, matching the compliance profile of the original CMLDM7003 TR.

Q: What is the operating temperature range for EM6K33T2R?

A: The EM6K33T2R specification provides maximum junction temperature of 150°C. The lower temperature limit is not documented in the provided parameters. The original CMLDM7003 TR and CMLDM7003G TR both specify -65°C to 150°C operating range.

Q: Can EM6K33T2R be used in applications requiring 280mA continuous drain current?

A: No. The EM6K33T2R is rated for 200mA continuous drain current at 25°C, which is below the 280mA requirement of the original CMLDM7003 TR. Use of this substitute in applications exceeding 200mA would violate the component's electrical ratings.

Q: Are the packages physically identical?

A: The CMLDM7003 TR, CMLDM7003G TR, and EM6K33T2R all use SOT-563 or SOT-666 compatible packages. Physical footprint compatibility is maintained across all three parts for PCB layout purposes. The EM6K33T2R supplier device package designation is EMT6, which maintains SOT-563 compatibility.

Q: What is the Moisture Sensitivity Level for all three parts?

A: All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or reflow processes.
