Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MLD1N06CLT4 are selected based on strict alignment with the following electrical and mechanical criteria:

Critical Matching Parameters:

• FET Type: N-Channel MOSFET (Metal Oxide technology)
• Package / Case: TO-252-3 DPAK (2 Leads + Tab) surface mount
• Drain to Source Voltage (Vdss): Equal to or greater than 65 V
• Continuous Drain Current (Id): Equal to or greater than 1 A at 25°C
• Drive Voltage compatibility: 4V and 5V gate drive support
• Operating Temperature Range: Minimum -50°C to +150°C or better
• Mounting Type: Surface Mount

All substitute parts listed maintain compatibility with the DPAK package footprint and support the same gate drive voltage levels. The substitute parts from Vishay Siliconix (IRLR024 series) exceed the voltage and current specifications of the original part, providing enhanced performance margins while maintaining electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The MLD1N06CLT4 is classified as obsolete, necessitating transition to active alternatives. The IRLR024 series from Vishay Siliconix provides direct functional equivalence with the following considerations:

Product Status: All substitute parts (IRLR024, IRLR024TR, IRLR024TRL, IRLR024TRR) maintain active product status, ensuring long-term availability and manufacturing support.

Electrical Compatibility: The IRLR024 series operates at 60 V Vdss, which is 5 V lower than the original MLD1N06CLT4 specification of 65 V. This represents a 7.7% reduction in voltage rating. Applications operating below 60 V are fully compatible. Applications requiring the full 65 V rating require design review to confirm operation within the reduced voltage specification.

Current and Power Handling: The IRLR024 series provides 14 A continuous drain current, significantly exceeding the 1 A specification of the MLD1N06CLT4. Power dissipation capability is 42 W at case temperature (Tc), matching the original 40 W specification. This enhanced current capacity provides design margin for thermal and electrical performance.

Package and Mounting: All substitute parts use the identical TO-252-3 DPAK package with surface mount configuration, ensuring direct PCB footprint compatibility without layout modifications.

Compliance and Certifications: Both the original part and all substitutes are RoHS non-compliant and carry MSL Level 1 (Unlimited) moisture sensitivity rating. ECCN and HTSUS classifications are identical across all parts.

Inventory Availability: Active substitute parts are available in significant quantities: IRLR024 (15,998 pcs), IRLR024TR (4,325 pcs), IRLR024TRL (4,400 pcs), and IRLR024TRR (987 pcs).

Frequently Asked Questions (FAQ)

Q: Can the IRLR024 series directly replace the MLD1N06CLT4 without PCB modifications?

A: Yes. All IRLR024 variants use the identical TO-252-3 DPAK package with the same pin configuration and footprint. No PCB layout changes are required for mechanical compatibility.

Q: What is the significance of the 60 V versus 65 V voltage rating difference?

A: The IRLR024 series operates at 60 V maximum Vdss, compared to the MLD1N06CLT4 at 65 V. This 5 V difference represents a 7.7% reduction in voltage headroom. Applications with maximum supply voltages at or below 60 V operate within specification. Applications requiring the full 65 V rating must be evaluated to confirm safe operation at the reduced rating or require alternative parts with higher voltage specifications.

Q: Are there differences between IRLR024, IRLR024TR, IRLR024TRL, and IRLR024TRR?

A: All four variants share identical electrical specifications and package configuration. The suffix designations (TR, TRL, TRR) indicate different tape-and-reel packaging formats or manufacturing lot codes. Electrical performance and PCB compatibility are equivalent across all variants.

Q: What are the key electrical advantages of the IRLR024 series over the MLD1N06CLT4?

A: The IRLR024 series provides 14 A continuous drain current versus 1 A for the original part, representing a 14-fold increase in current capacity. Gate charge is specified at 18 nC @ 5 V, and input capacitance is 870 pF @ 25 V, enabling faster switching performance. On-resistance is 100 mOhm @ 8.4A, 5V, providing lower conduction losses.

Q: Are the gate drive voltage requirements compatible?

A: Yes. Both the MLD1N06CLT4 and all IRLR024 variants support 4V and 5V drive voltage levels. Gate drive circuits designed for the original part operate without modification on the substitute parts.

Q: What is the operating temperature range compatibility?

A: The IRLR024 series operates from -55°C to +150°C (TJ), which extends the lower temperature limit by 5°C compared to the MLD1N06CLT4 range of -50°C to +150°C. This provides enhanced cold-temperature performance.

Q: Are there RoHS or compliance considerations for substitution?

A: Both the original MLD1N06CLT4 and all IRLR024 substitutes are RoHS non-compliant. No compliance advantage is gained through substitution. REACH status is unaffected for all parts. ECCN and HTSUS classifications remain identical.

Q: Which IRLR024 variant should be selected if multiple are available?

A: All four variants (IRLR024, IRLR024TR, IRLR024TRL, IRLR024TRR) are electrically and mechanically equivalent. Selection may be based on inventory availability, packaging format preference (tape-and-reel configuration), or supplier lead time. IRLR024 offers the highest inventory level at 15,998 pieces.
