Engineering Selection Recommendations

Primary Recommendation: IRLML6402TRPBF

The IRLML6402TRPBF is the direct equivalent of the obsolete IRLML6402TRPBF-1. This part maintains identical electrical specifications, package configuration, and thermal characteristics. The IRLML6402TRPBF carries Active product status from Infineon Technologies, ensuring long-term availability and supply chain continuity. This part is suitable for direct substitution in all applications previously utilizing the IRLML6402TRPBF-1.

Secondary Recommendation: PMV50XPR

The PMV50XPR from Nexperia USA Inc. provides functional equivalence with comparable electrical performance. This part delivers 3.6A continuous drain current, marginally lower than the main part specification, with improved on-resistance characteristics (60mOhm versus 65mOhm). The PMV50XPR is suitable for applications where the 3.6A rating meets design requirements and where Nexperia device qualification is acceptable.

Tertiary Recommendation: PMV65XPEAR

The PMV65XPEAR from Nexperia USA Inc. is qualified to AEC-Q100 automotive standards and carries automotive-grade designation. This part delivers 2.8A continuous drain current, which is lower than the main part specification. The PMV65XPEAR is suitable for automotive applications requiring AEC-Q100 qualification where the reduced current rating is compatible with circuit design parameters.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance, MSL Level 1 (Unlimited moisture sensitivity), and REACH Unaffected status, ensuring regulatory alignment with the original part.

Frequently Asked Questions (FAQ)

Q: Can IRLML6402TRPBF directly replace IRLML6402TRPBF-1 in existing designs?

A: Yes. The IRLML6402TRPBF is the direct equivalent with identical electrical specifications, package configuration, and thermal ratings. The primary difference is product status: IRLML6402TRPBF-1 is Obsolete, while IRLML6402TRPBF is Active. Direct substitution is appropriate for all applications.

Q: What are the key differences between PMV50XPR and the main part?

A: The PMV50XPR maintains the same 20V Vdss rating and operating temperature range. Differences include: continuous drain current of 3.6A (versus 3.7A), on-resistance of 60mOhm (versus 65mOhm), and lower gate threshold voltage of 900mV (versus 1.2V). These variations remain within acceptable substitution tolerances for P-Channel MOSFET applications.

Q: Is PMV65XPEAR suitable for non-automotive applications?

A: Yes. PMV65XPEAR is suitable for non-automotive applications. However, the continuous drain current rating of 2.8A is lower than the main part specification of 3.7A. Substitution is appropriate only when circuit design requirements are compatible with the reduced current rating.

Q: Are all substitute parts available in the same package configuration?

A: Yes. All substitute parts are packaged in TO-236-3, SC-59, or SOT-23-3 surface mount configurations, identical to the main part. Pin-to-pin compatibility is maintained across all listed substitutes.

Q: What is the significance of the Obsolete status for IRLML6402TRPBF-1?

A: Obsolete status indicates that Infineon Technologies has discontinued production and support for this part. The IRLML6402TRPBF (Active status) is the recommended replacement, ensuring access to current manufacturing, technical support, and long-term supply availability.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All substitute parts are ROHS3 compliant, carry MSL Level 1 (Unlimited), and maintain REACH Unaffected status, matching the regulatory compliance profile of the main part.

Q: What is the difference between Ta and Tc power dissipation ratings?

A: Ta (ambient temperature) represents power dissipation at 25°C ambient conditions. Tc (case temperature) represents power dissipation when the device case is maintained at a specified temperature through external cooling. PMV50XPR and PMV65XPEAR provide both ratings, enabling thermal design flexibility in applications requiring enhanced heat dissipation.
