Substitute Part Grouping Explanation

Substitution of the FCC16501ADTP with the SF-0603S050-2 is permissible based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Current Rating: Both parts rated at 500 mA
• Package / Case: Both use 0603 (1608 Metric) surface mount package
• Mounting Type: Both are surface mount components
• Physical Dimensions: Compatible footprint (1.60mm x 0.80mm x 0.45mm)
• RoHS Status: Both ROHS3 Compliant
• Moisture Sensitivity Level: Both rated MSL 1 (Unlimited)
• REACH Status: Both REACH Unaffected
• ECCN Classification: Both EAR99

Differing Parameters:

• Voltage Rating - DC: FCC16501ADTP rated 36 V; SF-0603S050-2 rated 50 V
• DC Cold Resistance: FCC16501ADTP 0.33 Ohms; SF-0603S050-2 0.175 Ohms
• Operating Temperature Range: FCC16501ADTP -55°C ~ 125°C; SF-0603S050-2 -20°C ~ 105°C
• Breaking Capacity: FCC16501ADTP 35A; SF-0603S050-2 50A
• Approval Agency: FCC16501ADTP CSA, UL; SF-0603S050-2 UL only

The SF-0603S050-2 operates at a higher voltage rating (50 V vs. 36 V), making it suitable for circuits designed for the FCC16501ADTP where the actual operating voltage does not exceed 36 V DC. The lower DC cold resistance of the substitute part results in reduced voltage drop across the fuse element during normal operation.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The FCC16501ADTP remains the specified component for applications requiring the full -55°C to 125°C operating temperature range and dual CSA/UL certification. This part is suitable for circuits operating at or below 36 V DC with standard industrial temperature requirements.

Substitute Part Selection: The SF-0603S050-2 is suitable as a substitute when the FCC16501ADTP is unavailable, provided that:

• The circuit operating voltage does not exceed 36 V DC (the substitute is rated to 50 V DC and will function correctly at lower voltages)
• The operating temperature range of -20°C to 105°C is acceptable for the application
• UL certification alone satisfies regulatory requirements (CSA certification is not provided by the substitute)
• The lower DC cold resistance (0.175 Ohms vs. 0.33 Ohms) does not create thermal or performance conflicts in the circuit design

Both parts maintain identical current ratings (500 mA), package form factors (0603), and surface mount compatibility, ensuring direct PCB footprint compatibility and assembly process alignment.

Frequently Asked Questions (FAQ)

Q: Can the SF-0603S050-2 be used as a direct replacement for the FCC16501ADTP in all applications?

A: The SF-0603S050-2 is mechanically and electrically compatible for circuits operating at 36 V DC or lower. However, if CSA certification is a regulatory requirement for your application, the FCC16501ADTP must be used, as the substitute carries only UL approval. Additionally, if your application requires operation below -20°C or above 105°C, the FCC16501ADTP's extended temperature range (-55°C to 125°C) is necessary.

Q: What is the impact of the different DC cold resistance values?

A: The SF-0603S050-2 has a lower DC cold resistance (0.175 Ohms) compared to the FCC16501ADTP (0.33 Ohms). This results in lower voltage drop and reduced power dissipation across the fuse element during normal circuit operation. For most applications, this difference is beneficial. However, circuit designs that depend on the specific resistance characteristics of the FCC16501ADTP should be evaluated before substitution.

Q: Are both parts compatible with the same PCB footprint?

A: Yes. Both the FCC16501ADTP and SF-0603S050-2 use the 0603 (1608 Metric) surface mount package with compatible physical dimensions (1.60mm length x 0.80mm width x 0.45mm height). They are directly interchangeable from a PCB layout and assembly perspective.

Q: What is the difference in breaking capacity between these parts?

A: The FCC16501ADTP has a breaking capacity of 35A at rated voltage, while the SF-0603S050-2 has a breaking capacity of 50A at rated voltage. Both values exceed typical circuit requirements for 500 mA fuses and do not affect substitution suitability for standard applications.

Q: Does the substitute part have the same response time characteristics?

A: The FCC16501ADTP response time specification is not provided in the technical data. The SF-0603S050-2 is specified as a Slow Blow fuse. If response time characteristics are critical to your application, verify that Slow Blow operation is compatible with your circuit protection requirements.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the FCC16501ADTP and SF-0603S050-2 are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards for electronic components.
