MF-PSHT010KX-2 Equivalent & Substitute Parts

Part Overview

The MF-PSHT010KX-2 is a Polymeric PTC Resettable Fuse manufactured by Bourns Inc. in the Multifuse® series. This surface mount component operates at a maximum voltage of 16V with a hold current of 100 mA and is housed in an 0805 (2012 Metric) package with concave geometry. The device is rated for AEC-Q200 compliance and is ROHS3 compliant. As an active product with substantial inventory availability, equivalent and substitute parts may be required for design flexibility, supply chain optimization, or application-specific voltage and current requirements that differ from the primary specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MF-PSHT010KX-2 is determined by compatibility across the following critical parameters:

Package and Mounting Compatibility: The substitute part must be housed in an 0805 (2012 Metric) surface mount package to ensure mechanical and electrical compatibility with existing PCB layouts and assembly processes.

Electrical Characteristics: The substitute part must maintain the same hold current (Ih) specification of 100 mA maximum. This parameter is fundamental to the protective function of the resettable fuse and cannot be altered without affecting circuit protection behavior.

Voltage Rating: While the MF-PSHT010KX-2 operates at a maximum of 16V, substitute parts may operate at higher voltage ratings. A higher voltage rating does not compromise functionality in lower-voltage applications and provides design flexibility for circuits operating at different voltage levels.

Compliance and Environmental Ratings: Substitute parts must maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity level to ensure regulatory conformance and manufacturing compatibility.

The PTS080524V010 from Eaton - Electronics Division meets these substitution criteria through identical package geometry, matching hold current specification, and equivalent compliance certifications, while offering an elevated voltage rating of 24V suitable for higher-voltage circuit protection applications.

Parameter Comparison

Engineering Selection Recommendations

MF-PSHT010KX-2 (Bourns Inc.): Select this part for applications requiring AEC-Q200 compliance certification. The Multifuse® series designation and active product status ensure long-term availability and supply chain stability. The 16V maximum voltage rating is appropriate for standard low-voltage circuit protection applications. Concave package geometry may be specified for particular PCB assembly requirements.

PTS080524V010 (Eaton - Electronics Division): Select this part for applications operating at voltages up to 24V or requiring higher maximum current handling capacity (100A versus 40A). The PTS0805 series maintains ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing processes. The 300 mA trip current specification differs from the Bourns part and must be evaluated against circuit protection requirements.

Both parts are active products with ROHS3 compliance and unlimited moisture sensitivity ratings, supporting standard surface mount assembly and long-term procurement viability.

Frequently Asked Questions (FAQ)

Q: Can the PTS080524V010 be used as a direct replacement for the MF-PSHT010KX-2 in a 16V circuit?

A: The PTS080524V010 is mechanically and electrically compatible with 16V applications. The 24V voltage rating of the Eaton part does not prevent operation in lower-voltage circuits. However, the trip current specification differs (300 mA versus 500 mA), requiring verification that circuit protection thresholds remain appropriate for the application.

Q: Are there package compatibility concerns between these two parts?

A: Both parts are housed in 0805 (2012 Metric) surface mount packages with identical footprint dimensions (0.085" L x 0.053" W / 2.15mm x 1.35mm). The MF-PSHT010KX-2 specifies concave geometry, while the PTS080524V010 does not. Verify PCB assembly specifications to confirm whether concave geometry is required for your application.

Q: Do both parts meet the same compliance standards?

A: Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings. The MF-PSHT010KX-2 includes AEC-Q200 certification. Verify whether AEC-Q200 compliance is required for your application before selecting the Eaton substitute.

Q: What is the significance of the different trip current specifications?

A: The MF-PSHT010KX-2 trips at 500 mA, while the PTS080524V010 trips at 300 mA. This difference affects the circuit protection response time and threshold. Applications requiring specific trip current behavior must select the part matching the circuit protection design specification.

Q: Are both parts suitable for high-temperature applications?

A: Both parts operate across the -40°C to 125°C temperature range, supporting standard industrial and automotive thermal environments. Verify that your specific application thermal profile falls within this operating range.
