STT2PF60L Equivalent & Substitute Parts

Part Overview

The STT2PF60L is a P-Channel MOSFET manufactured by STMicroelectronics, rated for 60V drain-to-source voltage with 2A continuous drain current in a SOT-23-6 surface mount package. This device is part of the STripFET™ II series and is classified as obsolete. Due to its obsolete status, equivalent substitute parts from active manufacturers are necessary to maintain design continuity and ensure long-term component availability for new production and field replacements.

Engineering Selection Recommendations

ZXMP6A17E6TA (Primary Substitute)

The ZXMP6A17E6TA is the preferred substitute for the STT2PF60L. This part is manufactured by Diodes Incorporated and maintains active product status. It provides identical Vdss (60V) and Vgs(th) (1V @ 250µA) specifications, with superior continuous drain current (2.3A versus 2A) and lower on-state resistance (125 mOhm versus 250 mOhm). The device is qualified to AEC-Q101 automotive standards and operates across the extended temperature range of -55°C to 150°C. All regulatory compliance requirements (ROHS3, REACH Unaffected) are met. The SOT-23-6 package is mechanically and electrically compatible with the original part.

ZXMP10A17E6TA (Secondary Substitute)

The ZXMP10A17E6TA is a secondary substitute option from Diodes Incorporated with active product status. This part features a higher Vdss rating (100V) suitable for applications requiring increased voltage margin. However, the continuous drain current is reduced to 1.3A, which falls below the 2A specification of the STT2PF60L. This part is appropriate only for designs where the 60V voltage rating is insufficient and where the reduced current capacity is acceptable. The gate threshold voltage is elevated to 4V, which may require circuit design adjustments. All regulatory compliance requirements are met.

Compliance and Regulatory Status

Both substitute parts maintain ROHS3 compliance and REACH Unaffected status, ensuring compatibility with current environmental and regulatory requirements. Moisture sensitivity level remains at MSL 1 (Unlimited) for both substitutes, matching the original part's handling requirements.

Frequently Asked Questions (FAQ)

Q: Can the ZXMP6A17E6TA directly replace the STT2PF60L without circuit modifications?

A: The ZXMP6A17E6TA is pin-compatible and functionally equivalent within the specified electrical parameters. The identical Vdss (60V) and Vgs(th) (1V) ratings, combined with superior current and resistance specifications, allow direct substitution in most applications. However, the increased gate charge (17.7 nC versus 7 nC) may affect switching speed in gate-drive-limited circuits.

Q: Why is the ZXMP10A17E6TA listed as a secondary substitute despite higher voltage rating?

A: The ZXMP10A17E6TA has a continuous drain current rating of 1.3A, which is below the 2A requirement of the STT2PF60L. While the higher 100V Vdss provides additional voltage margin, the reduced current capacity makes it unsuitable for applications requiring the full 2A specification. This part is appropriate only when voltage headroom is critical and current requirements can be reduced.

Q: Are the substitute parts available in the same packaging as the STT2PF60L?

A: Yes, both substitute parts are supplied in SOT-23-6 surface mount packages, identical to the original STT2PF60L. The mechanical footprint and pin configuration are compatible with existing PCB designs.

Q: What is the impact of the higher input capacitance in the ZXMP6A17E6TA?

A: The ZXMP6A17E6TA has an input capacitance of 637 pF at 30V, compared to 313 pF at 25V for the STT2PF60L. Higher input capacitance increases gate charge requirements and may slow switching transitions in applications with limited gate drive current. Circuit simulation or bench testing is appropriate to confirm performance in switching-speed-critical applications.

Q: Are both substitute parts qualified for automotive applications?

A: The ZXMP6A17E6TA carries AEC-Q101 automotive qualification. The ZXMP10A17E6TA does not list automotive qualification in the provided specifications. For automotive applications, the ZXMP6A17E6TA is the appropriate choice.

Q: What is the difference between Tc and Ta temperature measurement conditions?

A: Tc (case temperature) and Ta (ambient temperature) represent different measurement reference points for electrical specifications. The STT2PF60L uses Tc, while the substitute parts use Ta. Both devices support the same maximum junction temperature (TJ) of 150°C, ensuring thermal compatibility.

Q: Can the ZXMP10A17E6TA be used in a 60V application where the STT2PF60L was originally specified?

A: Yes, the ZXMP10A17E6TA can operate in 60V applications due to its 100V Vdss rating. However, the reduced continuous drain current (1.3A) must be verified against circuit current requirements. If the application requires the full 2A specification, this part is not suitable.
