Key Parameters

Substitute Part Grouping Explanation

Substitution of the MF-NSML600-2 is based on the following critical parameters that must remain constant:

• Voltage rating: 6V maximum
• Current hold rating: 6A maximum
• Current trip rating: 12A
• Package type: 1206 (3216 Metric), Concave surface mount
• Operating temperature range: -40°C to 85°C
• Polymeric PTC resettable fuse technology
• Regulatory compliance: cURus and TUV approval

The identified substitute part MF-NSML600/6-2 maintains all critical electrical and mechanical parameters within acceptable tolerances for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

The MF-NSML600/6-2 is the direct active equivalent for the obsolete MF-NSML600-2. Both parts are manufactured by Bourns Inc. and maintain identical voltage, current hold, and current trip specifications. The substitute part carries Active product status, ensuring continued availability and supply chain support.

Both parts meet identical regulatory requirements: cURus and TUV approval, ROHS3 compliance, and REACH unaffected status. The substitute part features a reduced maximum thickness (0.039" versus 0.047"), which provides improved PCB layout flexibility while maintaining the same footprint dimensions and mounting compatibility.

Minor variations in time to trip (5s versus 2s) and initial resistance (2 mOhms versus 1 mOhms) fall within the operational tolerance band for polymeric PTC resettable fuse technology and do not affect functional substitution in standard circuit protection applications.

Frequently Asked Questions (FAQ)

Q: Can MF-NSML600/6-2 be used as a direct replacement for MF-NSML600-2?

A: Yes. Both parts share identical voltage (6V), current hold (6A), current trip (12A), and package specifications (1206 Concave surface mount). The substitute part is manufactured by the same supplier and carries active product status.

Q: What is the difference in time to trip between these parts?

A: The MF-NSML600-2 trips in 2 seconds, while the MF-NSML600/6-2 trips in 5 seconds. Both values are within the operational specification range for polymeric PTC resettable fuses and do not affect compatibility in standard circuit protection applications.

Q: Are there packaging differences?

A: The MF-NSML600-2 is supplied in standard packaging, while the MF-NSML600/6-2 is available in Tape & Reel (TR) format. Both maintain identical footprint and mounting characteristics for PCB assembly.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both parts are cURus and TUV approved, ROHS3 compliant, and REACH unaffected. They carry identical ECCN (EAR99) and HTSUS (8533.40.8070) classifications.

Q: What is the thickness difference?

A: The MF-NSML600/6-2 has a maximum thickness of 0.039" (1.00mm) compared to 0.047" (1.20mm) for the MF-NSML600-2. This reduced profile improves PCB layout options while maintaining identical footprint dimensions.
