FMC16502WBTP Equivalent & Substitute Parts

Part Overview

The FMC16502WBTP is a surface mount chip fuse rated for 5 A at 32 V DC, packaged in the 0603 (1608 Metric) form factor. This component is designed for overcurrent protection in electronic circuits requiring compact, reliable fusing solutions. The part is currently Active in product status and maintains full compliance with RoHS3 and REACH regulations. Substitute parts are identified to address inventory availability, supply chain continuity, and equivalent functional performance in applications where the original part number may be unavailable.

Substitute Part Grouping Explanation

Substitution of the FMC16502WBTP is determined by strict equivalence across the following critical parameters:

• Current Rating: 5 A (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: 0.014 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)

The substitute part FMC16502WHTP meets all of these criteria and is therefore electrically and mechanically interchangeable with the FMC16502WBTP.

Parameter Comparison

Engineering Selection Recommendations

Both FMC16502WBTP and FMC16502WHTP are Active products manufactured by Kamaya Inc. with identical electrical and mechanical specifications. Selection between these parts is based on inventory availability and supply chain requirements rather than functional differences.

The FMC16502WHTP offers significantly higher inventory availability (14,180 pieces in stock) compared to the FMC16502WBTP (1,825 pieces in stock), making it the preferred choice for high-volume production runs or applications requiring extended lead time assurance.

Both parts carry CSA and UL approval certifications, maintain ROHS3 compliance, and are classified as REACH Unaffected. Both parts are suitable for applications operating across the -55°C to 125°C temperature range with identical breaking capacity and DC cold resistance characteristics.

Frequently Asked Questions (FAQ)

Q: Can FMC16502WHTP be used as a direct replacement for FMC16502WBTP?

A: Yes. The FMC16502WHTP is a direct electrical and mechanical equivalent. All critical parameters including current rating, voltage rating, package type, breaking capacity, and operating temperature range are identical.

Q: Are there any differences in PCB footprint 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 layouts require no modification.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both FMC16502WBTP and FMC16502WHTP carry identical CSA and UL approvals, maintain ROHS3 compliance, and are REACH Unaffected.

Q: What is the difference between these part numbers?

A: The part numbers differ only in their suffix designation (WBTP versus WHTP). This distinction does not reflect functional or electrical differences but rather internal manufacturing or packaging batch identification.

Q: Are there any thermal or performance differences?

A: No. Both parts operate across the identical temperature range of -55°C to 125°C and maintain the same DC cold resistance of 0.014 Ohms.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on current inventory availability and supply chain lead times. The FMC16502WHTP currently offers higher stock levels.
