Key Parameters

Substitute Part Grouping Explanation

Substitution of the FHC16252ABTP is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Current Rating: 2.5 A
• Voltage Rating (DC): 32 V
• Response Time: Fast Blow
• Package / Case: 0603 (1608 Metric)
• Mounting Type: Surface Mount

Compliance Requirements:

• RoHS3 Compliant status
• Moisture Sensitivity Level 1 (Unlimited)
• Active product status

The substitute part SF-0603F250-2 (Bourns Inc., SinglFuse™ SF-0603F series) meets all mandatory electrical and mechanical parameters. Both parts are surface mount fuses in identical package dimensions, share identical current and voltage ratings, and maintain equivalent fast-blow response characteristics. Both components are RoHS3 compliant with MSL 1 rating, ensuring compatibility in standard manufacturing and storage environments.

Parameter Comparison

Engineering Selection Recommendations

Both the FHC16252ABTP and SF-0603F250-2 are Active products with full RoHS3 compliance and MSL 1 rating, confirming suitability for standard surface mount assembly processes. The parts are electrically and mechanically equivalent across all critical protection parameters: 2.5 A current rating, 32 V DC voltage rating, fast-blow response, and 0603 package form factor.

The SF-0603F250-2 provides a higher breaking capacity (50 A versus 35 A) and lower DC cold resistance (0.024 Ohms versus 40 mOhms), representing enhanced performance characteristics. The FHC16252ABTP supports a wider operating temperature range (-55°C ~ 125°C versus -20°C ~ 105°C), which may be relevant for applications requiring extended low-temperature operation.

Selection between these parts is determined by application-specific requirements regarding operating temperature range and breaking capacity specifications. Both parts carry UL certification; the FHC16252ABTP additionally holds CSA and cUL approvals.

Frequently Asked Questions (FAQ)

Q: Can SF-0603F250-2 be used as a direct replacement for FHC16252ABTP in existing designs?

A: Yes. Both parts share identical current rating (2.5 A), voltage rating (32 V DC), response time (fast-blow), and package form factor (0603). Surface mount assembly compatibility is equivalent. Verify application-specific operating temperature requirements, as the FHC16252ABTP supports -55°C ~ 125°C while the SF-0603F250-2 operates within -20°C ~ 105°C.

Q: What are the key differences between these two fuses?

A: The primary differences are operating temperature range, breaking capacity, and DC cold resistance. The FHC16252ABTP provides wider temperature coverage (-55°C to 125°C) and lower cold resistance (40 mOhms). The SF-0603F250-2 offers higher breaking capacity (50 A versus 35 A) and operates within -20°C to 105°C. Both maintain identical electrical protection characteristics at rated current and voltage.

Q: Are both parts suitable for automated surface mount assembly?

A: Yes. Both components are Surface Mount fuses in 0603 (1608 Metric) package with MSL 1 (Unlimited) moisture sensitivity rating. Standard SMT assembly processes and storage conditions apply to both parts without additional handling requirements.

Q: Do these parts have equivalent safety certifications?

A: Both parts are RoHS3 compliant and carry UL certification. The FHC16252ABTP additionally holds CSA and cUL approvals. For applications requiring specific regional certifications, verify that the selected part meets all applicable standards.

Q: What is the significance of the DC cold resistance difference?

A: DC cold resistance affects voltage drop across the fuse during normal operation. The SF-0603F250-2 exhibits lower cold resistance (0.024 Ohms versus 40 mOhms), resulting in reduced power dissipation and heat generation during steady-state current flow. This characteristic may be advantageous in power-sensitive applications.

Q: Can these fuses be used interchangeably in new designs?

A: Yes, provided the application operating temperature range and breaking capacity requirements are satisfied. Confirm that the selected part's temperature range encompasses the intended operating environment and that the breaking capacity meets circuit protection specifications.
