Key Parameters

Substitute Part Grouping Explanation

Substitution of the SBF32502ASTP 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: 1206 (3216 Metric) (exact match required for PCB compatibility)

Mounting Type: Surface Mount (exact match required)

Breaking Capacity @ Rated Voltage: 50 A (exact match required for fault protection performance)

Approval Agency: CSA, UL (exact match required for regulatory compliance)

Operating Temperature Range: -55°C ~ 125°C (exact match required for thermal performance)

RoHS Status: ROHS3 Compliant (exact match required for environmental compliance)

The substitute part FHC32502ADTP meets all critical electrical and mechanical parameters. Minor variations in DC Cold Resistance (0.014 Ohms versus 0.012 Ohms) remain within acceptable tolerance for fuse operation and do not affect substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

Both the SBF32502ASTP and FHC32502ADTP are Active status components manufactured by Kamaya Inc. with identical electrical ratings, mechanical dimensions, and regulatory certifications. Selection between these parts is based on availability and inventory requirements rather than technical performance differences.

The FHC32502ADTP offers significantly higher inventory availability (48,011 pieces in stock versus 3,726 pieces for the SBF32502ASTP), making it the preferred choice for high-volume production runs and extended supply chain planning.

Both components satisfy CSA and UL approval requirements and maintain ROHS3 compliance. The minor DC Cold Resistance variation (0.002 Ohms difference) does not impact circuit protection performance or thermal characteristics within the specified operating temperature range of -55°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Can FHC32502ADTP be used as a direct replacement for SBF32502ASTP on existing PCB designs?

A: Yes. Both components share identical package dimensions (1206 / 3216 Metric), mounting type (Surface Mount), and electrical ratings (5 A, 32 V DC). No PCB layout modifications are required.

Q: What is the significance of the DC Cold Resistance difference between these parts?

A: The DC Cold Resistance values (0.012 Ohms for SBF32502ASTP and 0.014 Ohms for FHC32502ADTP) represent the resistance of the fuse element at room temperature. The 0.002 Ohms difference is within normal manufacturing tolerance for fuse components and does not affect circuit protection performance or thermal behavior.

Q: Are both parts suitable for applications requiring CSA and UL certification?

A: Yes. Both SBF32502ASTP and FHC32502ADTP carry identical CSA and UL approvals and maintain ROHS3 compliance, satisfying regulatory requirements for certified applications.

Q: What is the operating temperature range for these fuses?

A: Both components operate across the temperature range of -55°C to 125°C, providing consistent performance across industrial and commercial temperature environments.

Q: Is there a difference in moisture sensitivity between these parts?

A: No. Both components have Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no moisture-related handling restrictions during storage or assembly.

Q: Can these fuses be used interchangeably in high-volume manufacturing?

A: Yes. The electrical, mechanical, and regulatory equivalence of these parts supports interchangeable use in production environments. Selection may be based on inventory availability and supply chain optimization.
