MF-PSML075-2 Equivalent & Substitute Parts

Part Overview

The MF-PSML075-2 is a Polymeric PTC Resettable Fuse manufactured by Bourns Inc., rated for 6V maximum voltage with a 750 mA hold current. This component is designed for surface mount applications in the 0805 (2012 Metric) package format with a concave profile. The part is currently listed as obsolete, making identification of suitable substitutes essential for ongoing design support and component procurement. Active equivalent models are available from the same manufacturer series to maintain functional compatibility in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MF-PSML075-2 is determined by strict alignment of the following critical parameters:

• Maximum voltage rating: 6V
• Hold current (Ih): 750 mA maximum
• Trip current (It): 1.5 A
• Maximum current capacity: 50 A
• Post-trip resistance: 300 mOhms maximum
• Package format: 0805 (2012 Metric), Concave
• Mounting type: Surface Mount
• Component type: Polymeric PTC Resettable Fuse

The MF-PSML075/6-2 meets all substitution criteria as a direct equivalent within the Bourns Multifuse® series. Both parts share identical voltage, current ratings, resistance specifications, package dimensions, and thermal operating range. The substitute part is available in active production status with Tape & Reel packaging, providing improved supply chain availability compared to the obsolete original part number.

Parameter Comparison

Engineering Selection Recommendations

The MF-PSML075/6-2 is the direct substitute for the obsolete MF-PSML075-2. Both components carry identical regulatory certifications (cURus, TUV), maintain ROHS3 compliance, and share equivalent REACH status. The substitute part is currently in active production, ensuring long-term component availability and supply chain continuity.

Differences in initial resistance (40 mOhms vs. 20 mOhms) and trip time (200 ms vs. 300 ms) remain within the functional operating envelope of the Multifuse® series. Both parts maintain the same post-trip resistance maximum of 300 mOhms and identical voltage/current ratings. The marginal increase in thickness (0.028" vs. 0.024") is within standard PCB assembly tolerances for 0805 surface mount components.

Frequently Asked Questions (FAQ)

Q: Can MF-PSML075/6-2 be used as a direct replacement for MF-PSML075-2 in existing designs?

A: Yes. Both parts share identical voltage ratings (6V), hold current (750 mA), trip current (1.5 A), post-trip resistance (300 mOhms), operating temperature range (-40°C to 85°C), and package format (0805 Concave). Regulatory certifications and compliance status are equivalent.

Q: What are the differences between these two part numbers?

A: The substitute MF-PSML075/6-2 has a higher initial resistance specification (40 mOhms minimum vs. 20 mOhms) and faster trip time (200 ms vs. 300 ms). Thickness increases from 0.024" to 0.028". These variations remain within the functional parameters of the Multifuse® product line.

Q: Is the packaging format identical?

A: Both parts use the 0805 (2012 Metric) package with concave profile. The substitute is available in Tape & Reel packaging, while the original was supplied in standard packaging. PCB footprint and reflow soldering requirements are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts carry cURus and TUV approvals, maintain ROHS3 compliance, and have identical REACH status (REACH Unaffected). Moisture sensitivity level is 2A (4 Weeks) for both components.

Q: Why is the original part listed as obsolete?

A: The MF-PSML075-2 has been discontinued by the manufacturer. The MF-PSML075/6-2 represents the active production equivalent within the Multifuse® series, providing continued design support and component procurement options.
