Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FCC16252ADTP is determined by strict alignment of electrical and mechanical parameters. The following criteria establish valid substitute relationships:

Primary Substitution Criteria:

• Current Rating: 2.5 A (exact match required)
• Voltage Rating (DC): 32 V (exact match required)
• Package / Case: 0603 (1608 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)

Secondary Compatibility Factors:

• Response Time classification (Fast Blow vs. Slow Blow) affects circuit protection behavior
• Breaking Capacity rating must meet or exceed application requirements
• DC Cold Resistance influences voltage drop and thermal characteristics
• Operating Temperature range must encompass application environment
• Regulatory approvals (UL, CSA) confirm compliance with safety standards

The substitute part SF-0603S250-2 manufactured by Bourns Inc. satisfies all primary substitution criteria while maintaining equivalent electrical performance within the specified package envelope.

Engineering Selection Recommendations

FCC16252ADTP Selection Criteria: The Kamaya Inc. FCC16252ADTP is appropriate for applications requiring fast blow response characteristics with extended operating temperature range (-55°C to 125°C). This part carries dual agency approval (CSA and UL) and is suitable for high-temperature environments. The fast blow response provides rapid circuit interruption for sensitive electronic protection applications.

SF-0603S250-2 Selection Criteria: The Bourns Inc. SF-0603S250-2 is appropriate for applications requiring slow blow response characteristics with higher breaking capacity (50 A vs. 35 A). This part carries UL approval and operates within the -20°C to 105°C temperature range. The slow blow response accommodates inrush current conditions and is suitable for power supply and motor control applications. Lower DC cold resistance (0.02 Ohms vs. 0.045 Ohms) reduces voltage drop across the fuse element.

Substitution Compatibility: Both parts maintain identical current and voltage ratings with equivalent 0603 package form factor and surface mount configuration. Selection between these parts depends on circuit protection strategy (fast vs. slow blow response) and operating temperature requirements. Both parts satisfy RoHS3 compliance and carry recognized safety certifications.

Frequently Asked Questions (FAQ)

Q: Can SF-0603S250-2 directly replace FCC16252ADTP in all applications?

A: Direct replacement is limited by response time classification. The SF-0603S250-2 employs slow blow response while the FCC16252ADTP uses fast blow response. Slow blow fuses tolerate temporary overcurrent conditions, while fast blow fuses interrupt immediately. Application circuit design determines which response type is appropriate. Electrical ratings (2.5 A, 32 V DC) and package dimensions are equivalent.

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

A: The FCC16252ADTP exhibits 0.045 Ohms cold resistance compared to 0.02 Ohms for the SF-0603S250-2. This difference affects voltage drop across the fuse element during normal operation. Lower resistance (SF-0603S250-2) produces less heat dissipation and voltage drop. Higher resistance (FCC16252ADTP) may be relevant in low-voltage, high-current applications where voltage drop must be minimized.

Q: Are both parts suitable for the same temperature environments?

A: Operating temperature ranges differ. The FCC16252ADTP operates from -55°C to 125°C, while the SF-0603S250-2 operates from -20°C to 105°C. The Kamaya part supports extended low-temperature operation and higher maximum temperature. Application environment determines which temperature range is required.

Q: What is the difference in breaking capacity?

A: The FCC16252ADTP has 35 A breaking capacity while the SF-0603S250-2 has 50 A breaking capacity at rated voltage. Breaking capacity indicates the maximum fault current the fuse can safely interrupt. Higher breaking capacity (SF-0603S250-2) provides additional safety margin in high-fault-current applications.

Q: Do both parts carry equivalent safety certifications?

A: The FCC16252ADTP carries CSA and UL approvals. The SF-0603S250-2 carries UL approval. Both parts satisfy recognized safety standards. Application requirements may specify particular certification requirements (CSA vs. UL).

Q: Are the physical dimensions identical?

A: Dimensions are nearly identical with negligible variation. The FCC16252ADTP measures 0.063" L x 0.031" W x 0.018" H while the SF-0603S250-2 measures 0.063" L x 0.032" W x 0.018" H. The 0.001" width difference is within standard manufacturing tolerance and does not affect PCB layout or mechanical fit for 0603 package footprints.
