Key Parameters

Substitute Part Grouping Explanation

Substitution of the MCH6613-TL-E is determined by the following critical parameters:

Configuration Match: Both the main part and substitute must provide N and P-Channel MOSFET functionality in a single package.

Logic Level Gate Operation: The substitute must support logic level gate drive characteristics to maintain compatibility with existing control circuitry.

Voltage Rating: The substitute must meet or exceed the 30V Vdss requirement of the MCH6613-TL-E.

Current Capability: The substitute must provide continuous drain current ratings sufficient for the application, with the MCH6613-TL-E specifying 350mA and 200mA for the respective channels.

Power Dissipation: The substitute must support the 800mW maximum power rating.

Surface Mount Packaging: The substitute must be available in a surface mount configuration compatible with automated assembly processes.

Product Status and Compliance: Active product status and current compliance certifications (RoHS3, REACH Unaffected) are preferred for long-term availability and regulatory adherence.

Parameter Comparison

Engineering Selection Recommendations

The NDC7001C serves as a functional substitute for the MCH6613-TL-E based on the following engineering criteria:

Functional Equivalence: Both devices provide N and P-Channel MOSFET array functionality with logic level gate operation in a six-pin surface mount package configuration.

Electrical Superiority: The NDC7001C exceeds the MCH6613-TL-E specifications in voltage rating (60V versus 30V) and current capability (510mA and 340mA versus 350mA and 200mA), providing design margin for applications within the original voltage envelope.

Active Product Status: The NDC7001C is classified as active, ensuring ongoing availability, manufacturing support, and compliance with current regulatory standards. The MCH6613-TL-E is obsolete, presenting procurement and long-term support challenges.

Regulatory Compliance: The NDC7001C carries RoHS3 compliance certification and REACH Unaffected status, meeting current environmental and regulatory requirements. Both devices maintain MSL 1 (Unlimited) moisture sensitivity classification.

Package Consideration: The NDC7001C uses SuperSOT™-6 (SOT-23-6 Thin, TSOT-23-6) packaging, which differs from the 6-MCPH flat lead package of the MCH6613-TL-E. PCB layout and footprint modifications are required for implementation.

Power Dissipation Trade-off: The NDC7001C maximum power rating is 700mW compared to 800mW for the MCH6613-TL-E. Applications operating near the 800mW limit require thermal analysis to confirm compatibility.

Frequently Asked Questions (FAQ)

Q: Can the NDC7001C directly replace the MCH6613-TL-E without PCB modifications?

A: No. The MCH6613-TL-E uses a 6-MCPH package with flat leads, while the NDC7001C uses SuperSOT™-6 (SOT-23-6 Thin) packaging. PCB footprint and layout changes are required. Pin-to-pin functional mapping must be verified against device datasheets before implementation.

Q: What is the voltage rating difference, and does it affect compatibility?

A: The NDC7001C is rated for 60V Vdss compared to 30V for the MCH6613-TL-E. This higher rating provides design margin and does not create compatibility issues for applications operating at or below 30V. The substitute is suitable for circuits designed for the original 30V specification.

Q: Are the current ratings of the NDC7001C sufficient for MCH6613-TL-E applications?

A: Yes. The NDC7001C provides 510mA and 340mA continuous drain current ratings, exceeding the MCH6613-TL-E specifications of 350mA and 200mA. Current capability is not a limiting factor for substitution.

Q: What is the impact of the lower maximum power rating on the NDC7001C?

A: The NDC7001C is rated for 700mW maximum power dissipation versus 800mW for the MCH6613-TL-E. Applications operating near the 800mW limit require thermal analysis. For most standard applications, the 700mW rating is sufficient due to improved on-resistance characteristics of the NDC7001C.

Q: Are there differences in gate charge or input capacitance that affect circuit performance?

A: Gate charge is comparable (1.5nC versus 1.58nC at 10V). Input capacitance differs due to measurement conditions (20pF and 66pF at 25V for NDC7001C versus 7pF at 10V for MCH6613-TL-E). Circuit designers must account for these capacitance values in switching speed and drive current calculations.

Q: Is the NDC7001C suitable for new designs, or only for replacement of obsolete MCH6613-TL-E units?

A: The NDC7001C is suitable for both replacement and new design applications. Its active product status, RoHS3 compliance, and superior electrical specifications make it the preferred choice for ongoing development and long-term production.

Q: What are the moisture sensitivity and storage requirements for both parts?

A: Both the MCH6613-TL-E and NDC7001C carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions. Standard surface mount component storage and handling practices apply to both devices.
