Engineering Selection Recommendations

Both the SF-2410FA2000W-2 and SF-2410F2000W-2 maintain active product status and comply with ROHS3 requirements. The main part carries dual approval from cUL and UL, while the substitute carries UL approval. Both components are rated for identical DC voltage (65 V) and current (20 A) specifications with matching fast blow response and operating temperature ranges. The substitute part offers higher inventory availability (10359 pieces versus 3053 pieces). DC cold resistance differs slightly (0.0029 Ohms versus 0.0034 Ohms), and breaking capacity specifications vary at DC ratings (100A versus 50A DC). Selection between these parts should be based on inventory requirements, specific breaking capacity needs at DC ratings, and approval agency requirements for the target application.

Frequently Asked Questions (FAQ)

Q: Can SF-2410F2000W-2 be used as a direct replacement for SF-2410FA2000W-2?

A: Yes, both parts share identical current rating (20 A), DC voltage rating (65 V), response time (fast blow), package (2410 / 6125 Metric), and physical dimensions. Both are surface mount board mount fuses with matching operating temperature ranges and melting I²t values.

Q: What are the differences between these two parts?

A: The substitute part (SF-2410F2000W-2) includes AC voltage rating (65 V) not specified in the main part. DC cold resistance differs (0.0034 Ohms versus 0.0029 Ohms). Breaking capacity at DC is rated at 50A for the substitute versus 100A for the main part. Approval agencies differ (UL only for substitute versus cUL and UL for main part). REACH status differs (affected for substitute, unaffected for main part).

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.240" L x 0.098" W x 0.085" H (6.10mm x 2.49mm x 2.16mm), ensuring identical PCB footprint and mechanical compatibility.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Which part should be selected for new designs?

A: Selection depends on specific application requirements. If DC breaking capacity of 100A is required, use SF-2410FA2000W-2. If AC voltage rating is needed, use SF-2410F2000W-2. Both parts are active and suitable for new designs. Verify approval agency requirements (cUL/UL versus UL only) against application standards.
