• Current - Hold (Ih) Maximum: 170 mA
• Current - Trip (It): 340 mA
• Current - Maximum: 40 A
• Time to Trip: 3 s
• Resistance - Initial (Ri) Minimum: 2 Ohms
• Resistance - Post Trip (R1) Maximum: 8 Ohms
• Operating Temperature Range: -40°C to 85°C

Mechanical Parameters (Must Match):

• Mounting Type: Through Hole
• Package / Case: Radial, Disc
• Size / Dimension: 0.291" Dia x 0.122" T (7.40mm x 3.10mm)
• Height - Seated Maximum: 0.500" (12.70mm)
• Lead Spacing: 0.201" (5.10mm)

Regulatory Compliance (Must Match):

• RoHS3 Compliant
• REACH Unaffected

All identified substitute parts meet these criteria and are classified as Polymeric PTC Resettable Fuses with Active product status.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—0ZRR0017FF1E (Bel Fuse Inc.), MF-R017 (Bourns Inc.), and PFRA.017 (SCHURTER Inc.)—are direct parametric equivalents to the MF-R017-0-17. Each part maintains identical electrical specifications, mechanical dimensions, and regulatory compliance status.

Compliance Considerations:

The MF-R017-0-17 carries AEC-Q200 automotive qualification with approval agencies cUL, cURus, TUV, and UL. The substitute parts 0ZRR0017FF1E and PFRA.017 carry approvals from cURus and TUV, while MF-R017 carries approvals from cURus and TUV. All parts are ROHS3 compliant and REACH unaffected.

Product Availability:

MF-R017 (Bourns) offers the highest inventory level at 3,395 pieces. 0ZRR0017FF1E (Bel Fuse) provides 842 pieces, and PFRA.017 (SCHURTER) provides 998 pieces. The original MF-R017-0-17 maintains 1,121 pieces in stock.

Moisture Sensitivity:

MF-R017-0-17 and MF-R017 are rated MSL 1 (Unlimited). 0ZRR0017FF1E and PFRA.017 are rated MSL Not Applicable, indicating no moisture sensitivity constraints.

Frequently Asked Questions (FAQ)

Q: Can the 0ZRR0017FF1E substitute for the MF-R017-0-17 in all applications?

A: The 0ZRR0017FF1E is a parametric equivalent with identical electrical and mechanical specifications. Both parts operate at 60V maximum voltage with 170 mA hold current and 340 mA trip current. Physical dimensions, lead spacing, and mounting type are identical. The primary difference is manufacturer and approval agency coverage. The 0ZRR0017FF1E carries cURus and TUV approvals, while the MF-R017-0-17 includes additional cUL and UL approvals.

Q: What is the difference between MF-R017 and MF-R017-0-17?

A: Both parts are manufactured by Bourns Inc. in the Multifuse® MF-R series and share identical electrical parameters, mechanical dimensions, and operating characteristics. The MF-R017 is the base product number, while MF-R017-0-17 represents a specific variant designation. All electrical and mechanical specifications are equivalent.

Q: Are the PFRA.017 and MF-R017-0-17 mechanically interchangeable?

A: Yes. Both parts feature identical radial disc package dimensions of 0.291" diameter by 0.122" thickness, with 0.500" maximum seated height and 0.201" lead spacing. Through-hole mounting compatibility is confirmed for both components.

Q: What are the critical parameters for substitution?

A: Substitution eligibility is determined by matching voltage rating (60V), hold current (170 mA), trip current (340 mA), operating temperature range (-40°C to 85°C), initial resistance (2 Ohms minimum), post-trip resistance (8 Ohms maximum), and physical package dimensions. All identified substitutes meet these criteria.

Q: Do all substitute parts have the same regulatory approvals?

A: No. The MF-R017-0-17 carries approvals from cUL, cURus, TUV, and UL. The 0ZRR0017FF1E and PFRA.017 carry approvals from cURus and TUV. The MF-R017 carries approvals from cURus and TUV. All parts are ROHS3 compliant and REACH unaffected.

Q: What is the difference in moisture sensitivity between these parts?

A: The MF-R017-0-17 and MF-R017 are rated MSL 1 (Unlimited), indicating no moisture sensitivity constraints. The 0ZRR0017FF1E and PFRA.017 are rated MSL Not Applicable, also indicating no moisture sensitivity constraints. Both ratings are equivalent for practical application purposes.
