Parameter Comparison

Engineering Selection Recommendations

Full Electrical and Mechanical Equivalents:

SF-0603S200-2 and SF-0603SP200-2 are direct substitutes for the 0ABB-2000-TM. Both parts match all primary electrical specifications (2 A, 32 V DC, slow blow response) and mechanical parameters (0603 package, surface mount). Both carry UL approval and maintain identical melting I²t values of 0.115. The SF-0603S200-2 operates across -20°C to 105°C, while SF-0603SP200-2 extends to -40°C to 105°C. Selection between these two depends on application temperature requirements.

Extended Temperature Range Equivalents:

SF-0603SA200M-2 and SF-0603SP200M-2 provide extended operating temperature ranges matching the 0ABB-2000-TM specification of -55°C to 150°C. SF-0603SA200M-2 operates at 35 V DC (higher than the 32 V specification) with a melting I²t of 0.182 and cUL approval. SF-0603SP200M-2 maintains the 32 V DC rating with a melting I²t of 0.32 and no specified approval agency. Both are suitable for applications requiring the full -55°C to 150°C temperature envelope.

Alternative with Modified Characteristics:

SF-0603S200M-2 provides extended temperature range (-55°C to 125°C) but features a reduced breaking capacity of 35 A and lower melting I²t of 0.06. This part is suitable only for applications where the reduced breaking capacity and faster response characteristics are acceptable.

Compliance Considerations:

The 0ABB-2000-TM carries AEC-Q200 certification, indicating automotive-grade qualification. Substitute parts with UL or cUL approval (SF-0603S200-2, SF-0603SP200-2, SF-0603SA200M-2) are suitable for general industrial and consumer applications. Applications requiring AEC-Q200 certification should retain the original 0ABB-2000-TM part number.

Frequently Asked Questions (FAQ)

Q: Can SF-0603S200-2 be used as a direct replacement for 0ABB-2000-TM?

A: Yes. SF-0603S200-2 matches all primary electrical specifications (2 A, 32 V DC, slow blow) and mechanical parameters (0603 package, surface mount). Both parts have identical melting I²t values of 0.115 and 50 A breaking capacity. The primary difference is the operating temperature range: SF-0603S200-2 operates from -20°C to 105°C, while 0ABB-2000-TM operates from -55°C to 150°C. Selection depends on application temperature requirements.

Q: What is the difference between SF-0603SP200-2 and SF-0603S200-2?

A: Both parts are electrically identical (2 A, 32 V DC, slow blow, 0.115 melting I²t, 50 A breaking capacity). The difference is operating temperature range: SF-0603S200-2 operates from -20°C to 105°C, while SF-0603SP200-2 operates from -40°C to 105°C. SF-0603SP200-2 is suitable for applications requiring extended low-temperature performance.

Q: Why does SF-0603SA200M-2 have a 35 V DC rating instead of 32 V DC?

A: SF-0603SA200M-2 is rated for 35 V DC, which exceeds the 0ABB-2000-TM specification of 32 V DC. This part is suitable for applications operating at 32 V DC and provides additional voltage margin. The higher voltage rating does not affect compatibility with 32 V DC circuits.

Q: Can I use SF-0603S200M-2 in place of 0ABB-2000-TM?

A: SF-0603S200M-2 matches the current rating (2 A), voltage rating (32 V DC), response time (slow blow), and package (0603). However, it has a reduced breaking capacity of 35 A (compared to 50 A) and a lower melting I²t of 0.06 (compared to 0.115). This part is suitable only for applications where the reduced breaking capacity and faster response characteristics are acceptable.

Q: What is the significance of the "M" designation in part numbers like SF-0603S200M-2?

A: The "M" designation indicates a modified or variant version of the base part. SF-0603S200M-2 and SF-0603SP200M-2 feature different physical dimensions and electrical characteristics compared to their non-M counterparts. Refer to the parameter comparison table for specific differences in melting I²t, breaking capacity, and operating temperature range.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (SF-0603S200-2, SF-0603S200M-2, SF-0603SA200M-2, SF-0603SP200-2, SF-0603SP200M-2) are RoHS3 compliant and maintain Moisture Sensitivity Level 1 (Unlimited), matching the 0ABB-2000-TM specifications.

Q: Which substitute part should I select for automotive applications?

A: The 0ABB-2000-TM carries AEC-Q200 certification, which is required for automotive-grade applications. Substitute parts do not carry AEC-Q200 certification. For automotive applications requiring AEC-Q200 qualification, the original 0ABB-2000-TM part number should be retained.

Q: What is the difference in DC cold resistance between the main part and substitutes?

A: The 0ABB-2000-TM has a DC cold resistance of 78 Ohms, which is significantly higher than the Bourns substitute parts (0.026 to 0.052 Ohms). This difference reflects different fuse element designs. For applications sensitive to DC cold resistance characteristics, verify that the substitute part's resistance value is acceptable for the circuit design.
