Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FHC32502ADTP are qualified based on the following critical parameters:

Electrical Equivalence:

• Current Rating: 5 A
• Voltage Rating (DC): 32 V
• Breaking Capacity @ Rated Voltage: 50 A

Mechanical Compatibility:

• Package / Case: 1206 (3216 Metric)
• Mounting Type: Surface Mount
• Physical dimensions compatible with PCB footprint

Regulatory & Compliance:

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• Approval Agency certification (UL and/or CSA)

Parts meeting all three categories are classified as direct substitutes. Variations in secondary parameters such as DC Cold Resistance, Response Time, or Operating Temperature Range do not disqualify substitution when primary electrical and mechanical specifications align.

Parameter Comparison

Engineering Selection Recommendations

FHC32502ADTP (Primary Part): Active product with CSA and UL approval. Operating temperature range of -55°C to 125°C supports extended environmental applications. Suitable for standard circuit protection requirements in surface mount designs.

SBF32502ASTP (Parametric Equivalent): Active product manufactured by Kamaya Inc. with identical electrical specifications and package dimensions to FHC32502ADTP. CSA and UL approval and identical operating temperature range ensure direct functional equivalence. Lower DC Cold Resistance (0.012 Ohms vs. 0.014 Ohms) represents a minor performance variation within acceptable tolerance for fuse applications.

SF-1206S500-2 (Cross-Manufacturer Substitute): Active product manufactured by Bourns Inc. with identical electrical specifications and 1206 package classification. UL approval confirmed. Physical dimensions vary slightly (0.122" L x 0.061" W x 0.024" H vs. 0.126" L x 0.063" W x 0.026" H), remaining within 1206 package tolerance. Operating temperature range (-20°C to 105°C) is narrower than primary part; applications requiring operation below -20°C or above 105°C require primary part selection. Slow Blow response time characteristic differs from primary part specification.

Frequently Asked Questions (FAQ)

Q: Can SBF32502ASTP replace FHC32502ADTP in all applications?

A: Yes. Both parts share identical current rating (5 A), voltage rating (32 V DC), package (1206), mounting type (Surface Mount), breaking capacity (50 A), approval agencies (CSA, UL), and operating temperature range (-55°C to 125°C). DC Cold Resistance variation (0.012 Ohms vs. 0.014 Ohms) does not affect substitution eligibility.

Q: What are the limitations of SF-1206S500-2 as a substitute?

A: SF-1206S500-2 has a narrower operating temperature range (-20°C to 105°C) compared to FHC32502ADTP (-55°C to 125°C). Applications requiring operation below -20°C or above 105°C must use FHC32502ADTP or SBF32502ASTP. Physical dimensions are slightly smaller (0.122" L x 0.061" W x 0.024" H), which remains within 1206 package specification but may require PCB footprint verification. UL approval is confirmed; CSA approval is not listed.

Q: Are all substitute parts available in the same packaging format?

A: Yes. FHC32502ADTP, SBF32502ASTP, and SF-1206S500-2 are all supplied in Tape & Reel (TR) packaging for automated assembly processes.

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

A: DC Cold Resistance values (0.014 Ohms, 0.012 Ohms, and 0.01 Ohms respectively) represent minor variations in fuse element design. All values remain within acceptable operating parameters for 5 A fuse applications and do not disqualify substitution.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. FHC32502ADTP, SBF32502ASTP, and SF-1206S500-2 are all ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What is the difference between "Parametric Equivalent" and "Direct Manufacturer" classifications?

A: SBF32502ASTP is a parametric equivalent manufactured by the same supplier (Kamaya Inc.) with identical specifications. SF-1206S500-2 is a cross-manufacturer substitute from Bourns Inc. with equivalent electrical and mechanical specifications but from a different manufacturer. Both are valid substitutes based on electrical and mechanical compatibility.
