MF-VS175-0 Equivalent & Substitute Parts

Part Overview

The MF-VS175-0 is a polymeric PTC resettable fuse manufactured by Bourns Inc. under the Multifuse® MF-VS series. This component provides overcurrent protection at 12V with a 1.75 A hold current rating and is designed for user-defined strap mounting applications. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating. Alternative models are identified to support supply chain flexibility and application-specific requirements where equivalent electrical and mechanical parameters are maintained.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MF-VS175-0 is determined by the following critical parameters:

• Voltage rating must equal or exceed 12V maximum
• Current hold (Ih) rating must be within the range of 1.7 A to 1.75 A
• Package type must be strap configuration with user-defined mounting
• Polymeric PTC resettable fuse technology
• RoHS3 compliance requirement
• Operating temperature range compatibility

The VLR170F from Littelfuse Inc. qualifies as a substitute based on matching voltage, similar hold current specification, identical package type, and equivalent compliance certifications. Variations in trip current, time to trip, and resistance characteristics remain within acceptable engineering tolerances for this product category.

Parameter Comparison

Engineering Selection Recommendations

Both the MF-VS175-0 and VLR170F maintain active product status with full RoHS3 compliance and regulatory certifications suitable for industrial applications. The MF-VS175-0 offers a broader operating temperature range extending to 85°C, while the VLR170F provides additional certification coverage through CSA and UL approvals. Selection between these parts should be based on specific application temperature requirements and regional certification mandates. Both components are polymeric PTC resettable fuses in strap configuration with equivalent voltage and hold current specifications.

Frequently Asked Questions (FAQ)

Q: Can the VLR170F directly replace the MF-VS175-0 in all applications?

A: The VLR170F is electrically compatible as a substitute where the operating temperature does not exceed 70°C. The MF-VS175-0 supports operation up to 85°C. Both parts maintain 12V voltage rating and similar hold current specifications within 1.7 A to 1.75 A range.

Q: What are the differences in trip characteristics between these parts?

A: The VLR170F has a higher trip current (4.1 A vs 4.6 A) and longer time to trip (5 s vs 3 s). These differences reflect different protection profiles and should be evaluated against specific circuit requirements.

Q: Are both parts RoHS3 compliant?

A: Yes, both the MF-VS175-0 and VLR170F are RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: What certifications does each part carry?

A: The MF-VS175-0 carries cURus and TUV approvals. The VLR170F carries CSA, TUV, and UL approvals. Both meet regulatory requirements for their respective markets.

Q: Are the strap packages mechanically identical?

A: Both parts use user-defined strap mounting configuration. The VLR170F specifies dimensions of 0.866" L x 0.146" W (22.00mm x 3.70mm) with 0.032" (0.80mm) thickness. Mechanical compatibility should be confirmed for specific mounting applications.
