Equivalent & Substitute Parts for 60R017XU

Part Overview

The Littelfuse 60R017XU is a polymeric PTC resettable fuse rated for 60V maximum voltage with a 170 mA hold current. This through-hole radial disc component is designed for circuit protection in applications requiring automatic reset capability after fault conditions. The part is active in production status with full RoHS3 compliance and cURus approval. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to supply constraints, design flexibility, or application-specific requirements.

Substitute Part Grouping Explanation

Substitute parts for the 60R017XU are classified based on strict electrical and mechanical compatibility criteria. The primary substitution logic is determined by the following parameters:

Voltage Rating: All substitutes must maintain 60V maximum voltage rating
Current - Hold (Ih): All substitutes must support 170 mA hold current specification
Current - Trip (It): All substitutes must trip at 340 mA
Mounting Type: All substitutes must be through-hole radial disc configuration
Lead Spacing: All substitutes must maintain 0.201" (5.10mm) lead spacing for PCB compatibility
Operating Temperature Range: All substitutes must support -40°C ~ 85°C
Compliance: All substitutes must maintain cURus approval and RoHS3 compliance status

Direct equivalents meet all electrical and mechanical parameters identically. The Eaton PTR060V0017-BK and Bourns MF-R017 are direct functional equivalents with identical hold current, trip current, and voltage ratings. The SCHURTER PFRA.017 is also a direct electrical equivalent with identical performance specifications.

Engineering Selection Recommendations

The Eaton PTR060V0017-BK is a direct electrical equivalent with identical performance specifications. Lead spacing differs by 0.004" (0.10mm), which may require PCB layout verification for applications with tight lead-to-pad tolerances. Eaton certification includes both cURus and TUV approval.

The Bourns MF-R017 is a direct electrical equivalent with identical lead spacing and voltage/current ratings. Initial resistance is lower at 2 Ohms minimum compared to 3.3 Ohms for the 60R017XU, which may result in marginally lower voltage drop during normal operation. Bourns provides cURus and TUV certification with ROHS3 compliance.

The SCHURTER PFRA.017 is a direct electrical equivalent with identical lead spacing, voltage, and current specifications. Initial resistance is 2 Ohms minimum, matching the Bourns specification. SCHURTER provides cURus and TUV certification with ROHS3 compliance. All three substitute parts maintain active production status.

Frequently Asked Questions (FAQ)

Q: Can the PTR060V0017-BK be used as a direct replacement for the 60R017XU?

A: The PTR060V0017-BK is electrically equivalent with identical voltage, hold current, and trip current specifications. Lead spacing differs by 0.004" (0.10mm), which is within typical PCB manufacturing tolerances but should be verified for applications with constrained pad spacing.

Q: What is the difference between the initial resistance values of these parts?

A: The 60R017XU has a minimum initial resistance of 3.3 Ohms, while the MF-R017 and PFRA.017 specify 2 Ohms minimum. Lower initial resistance results in reduced voltage drop during normal circuit operation. Both values are within acceptable limits for 170 mA hold current applications.

Q: Are all substitute parts RoHS3 compliant?

A: The 60R017XU, MF-R017, and PFRA.017 are ROHS3 compliant. The PTR060V0017-BK is RoHS compliant but does not specify ROHS3 status. Verify compliance requirements for your specific application.

Q: Do all parts have the same approval certifications?

A: The 60R017XU carries cURus approval. The PTR060V0017-BK, MF-R017, and PFRA.017 all carry both cURus and TUV approval, providing additional certification coverage.

Q: Can I use parts with different current ratings as substitutes?

A: No. Substitute parts must maintain the 170 mA hold current and 340 mA trip current specifications. Parts with different current ratings (such as PFRA.010, PFRA.020, PFRA.025, PFRA.030, or PFRA.050) are not direct substitutes and will alter circuit protection behavior.

Q: What is the significance of lead spacing differences?

A: Lead spacing determines PCB pad layout compatibility. The 60R017XU, MF-R017, and PFRA.017 all use 0.201" (5.10mm) spacing. The PTR060V0017-BK uses 0.197" (5.00mm) spacing, a 0.004" difference that may require PCB layout adjustment depending on pad tolerance specifications.
