Key Parameters

Substitute Part Grouping Explanation

Substitution of the CMS01P10T-HF is determined by strict equivalence across the following critical parameters:

• FET Channel Type: P-Channel topology must be maintained
• Voltage Rating (Vdss): Minimum 100V rating required
• Current Rating (Id): Minimum 1.2A continuous drain current at 25°C
• On-Resistance (Rds On): Maximum 650 mOhm at specified gate voltage
• Package Configuration: SOT-23-3 surface mount package
• Thermal Performance: Operating temperature range of −55°C to 150°C (TJ)

The substitute part CMS01P10TA-HF meets all these criteria and is manufactured by the same supplier (Comchip Technology), ensuring design and functional compatibility with the original specification.

Engineering Selection Recommendations

The CMS01P10TA-HF is the manufacturer-recommended substitute for the obsolete CMS01P10T-HF. Selection of this substitute is supported by the following factors:

• Product Status: The substitute part is classified as Active, ensuring continued availability and supply chain support
• Regulatory Compliance: The CMS01P10TA-HF carries ROHS3 compliance certification, meeting current environmental and material restriction standards
• Moisture Sensitivity: MSL rating of 1 (Unlimited) indicates superior moisture handling characteristics compared to standard classifications
• Export Classification: Both parts share identical ECCN classification (EAR99), maintaining regulatory consistency
• Manufacturer Continuity: Both parts are produced by Comchip Technology, ensuring consistent design philosophy and quality standards

The substitute part maintains electrical and mechanical compatibility with the original specification while offering improved compliance status and active product lifecycle support.

Frequently Asked Questions (FAQ)

Q: Can the CMS01P10TA-HF be used as a direct replacement for the CMS01P10T-HF in existing designs?

A: Yes. The CMS01P10TA-HF is the manufacturer-recommended substitute and maintains identical electrical ratings (100V Vdss, 1.2A Id) and package configuration (SOT-23-3 surface mount). No circuit modifications are required.

Q: What is the primary reason for substitution?

A: The CMS01P10T-HF is classified as Obsolete. The CMS01P10TA-HF is an Active product from the same manufacturer, ensuring long-term availability and supply chain continuity.

Q: Are there any compliance differences between the two parts?

A: The CMS01P10TA-HF carries ROHS3 compliance certification and MSL rating of 1 (Unlimited), both of which exceed the requirements of the original part. These certifications support modern manufacturing and environmental standards.

Q: Is the package configuration identical?

A: Yes. Both parts use the SOT-23-3 surface mount package (also designated TO-236-3 or SC-59), ensuring identical PCB footprint and assembly compatibility.

Q: What is the ECCN classification for both parts?

A: Both the CMS01P10T-HF and CMS01P10TA-HF are classified as EAR99, maintaining consistent export control compliance.

Q: Are there any thermal performance differences?

A: Both parts operate across the same temperature range (−55°C to 150°C TJ) and share identical power dissipation ratings (1W Ta), ensuring equivalent thermal behavior in circuit applications.
