Substitute Part Grouping Explanation

The HVR600P160CFF has one identified substitute: the 600R160UR, also manufactured by Littelfuse Inc. Substitution eligibility is determined by the following critical parameters:

• Voltage rating: Both parts rated at 60V (600V Int)
• Current - Hold (Ih): Both rated at 160 mA maximum
• Current - Trip (It): Both rated at 320 mA
• Current - Max: Both rated at 3 A
• Resistance - Initial (Ri): Both minimum 4 Ohms
• Resistance - Post Trip (R1): Both maximum 18 Ohms
• Operating Temperature Range: Both -40°C ~ 85°C
• Mounting Type: Both through-hole radial disc configuration
• Physical Dimensions: Identical 0.630" L x 0.236" W (16.00mm x 6.00mm)
• Lead Spacing: Both 0.201" (5.10mm)
• Approval Certifications: Both cURus and TUV approved
• RoHS Compliance: Both ROHS3 compliant

The 600R160UR represents a direct electrical and mechanical equivalent suitable for replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The 600R160UR is the designated substitute for the obsolete HVR600P160CFF. Both components maintain identical electrical specifications across all critical parameters: voltage rating, hold current, trip current, maximum current, initial resistance, and post-trip resistance. Physical dimensions and lead spacing are identical, ensuring direct mechanical compatibility in through-hole radial disc applications.

The 600R160UR carries active product status from Littelfuse Inc., providing assured long-term availability and supply chain continuity. Both parts maintain equivalent regulatory compliance with cURus and TUV certifications and ROHS3 compliance status.

The primary difference between the two parts is the time-to-trip specification: the HVR600P160CFF trips at 7 seconds while the 600R160UR trips at 10 seconds. This variance must be evaluated against specific application requirements to determine suitability for your circuit protection design.

Frequently Asked Questions (FAQ)

Q: Can the 600R160UR be used as a direct replacement for the HVR600P160CFF?

A: The 600R160UR is electrically and mechanically equivalent to the HVR600P160CFF across all critical parameters including voltage, current ratings, resistance values, operating temperature, and physical dimensions. The components are pin-compatible for through-hole radial mounting. However, the difference in time-to-trip specification (7 seconds versus 10 seconds) must be evaluated for your specific application.

Q: What is the significance of the time-to-trip difference?

A: The HVR600P160CFF has a time-to-trip of 7 seconds, while the 600R160UR has a time-to-trip of 10 seconds. This parameter defines how quickly the PTC resettable fuse responds to overcurrent conditions. Applications with strict timing requirements for fault detection and circuit protection must account for this 3-second difference.

Q: Are both parts RoHS compliant?

A: Yes, both the HVR600P160CFF and 600R160UR are ROHS3 compliant and carry identical regulatory approvals from cURus and TUV.

Q: What is the difference in packaging between these parts?

A: The HVR600P160CFF is listed with standard packaging, while the 600R160UR is supplied in Cut Tape (CT) format. This affects procurement and handling but does not impact electrical or mechanical performance.

Q: Why is the HVR600P160CFF marked as obsolete?

A: The HVR600P160CFF is listed as obsolete by the manufacturer. The 600R160UR, part of the active POLY-FUSE® 600R series, represents the current production equivalent and is recommended for new designs and ongoing component procurement.
