Key Parameters

Substitute Part Grouping Explanation

Substitution of the FMC16501WHTP is determined by strict equivalence across the following critical parameters:

• Current Rating: 500 mA (exact match required)
• Voltage Rating - DC: 32 V (exact match required)
• Package / Case: 0603 (1608 Metric) (exact match required for PCB compatibility)
• Mounting Type: Surface Mount (exact match required)
• Breaking Capacity @ Rated Voltage: 35 A (exact match required)
• DC Cold Resistance: 0.26 Ohms (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Approval Agency: CSA, UL (exact match required for regulatory compliance)
• RoHS Status: ROHS3 Compliant (exact match required)

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes. No deviations in electrical or mechanical specifications are permitted for functional interchangeability.

Parameter Comparison

Frequently Asked Questions (FAQ)

Q: Can FMC16501WBTP be used as a direct replacement for FMC16501WHTP?

A: Yes. The FMC16501WBTP is a parametric equivalent with identical current rating, voltage rating, package dimensions, breaking capacity, DC cold resistance, operating temperature range, and regulatory approvals. Direct substitution is supported without circuit modification.

Q: Are there any differences in the 0603 package dimensions between these parts?

A: No. Both parts use the 0603 (1608 Metric) package with identical dimensions of 0.063" L x 0.031" W x 0.018" H (1.60mm x 0.80mm x 0.45mm). PCB footprints and placement are identical.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both FMC16501WHTP and FMC16501WBTP carry CSA and UL approvals, comply with ROHS3 requirements, and are REACH Unaffected. Regulatory compliance is equivalent.

Q: What is the significance of the DC Cold Resistance specification?

A: DC Cold Resistance of 0.26 Ohms is a critical parameter that determines the voltage drop across the fuse during normal operation. Both parts match this specification exactly, ensuring identical circuit performance and thermal characteristics.

Q: Can these fuses be used in AC applications?

A: The detailed description indicates these are rated for 500 mA AC and 32 V DC operation. The voltage rating of 32 V applies to DC circuits. AC application requirements must be evaluated separately based on circuit design specifications.

Q: What does Moisture Sensitivity Level 1 (Unlimited) mean?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. These parts do not require special moisture control during storage, handling, or assembly processes.
