Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 0ABB-2500-TM are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Compatibility Criteria:

• Current Rating: 2.5 A (exact match required)
• Voltage Rating (DC): 32 V or higher (32 V minimum acceptable)
• Response Time: Slow Blow (exact match required)
• Package / Case: 0603 (1608 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Fuse Type: Board Mount (Cartridge Style Excluded) (exact match required)

Secondary Compatibility Considerations:

• Breaking Capacity @ Rated Voltage: 50 A or higher (50 A minimum acceptable)
• Operating Temperature Range: Must encompass or exceed -55°C to 150°C
• RoHS Status: ROHS3 Compliant (maintained across all substitutes)
• Moisture Sensitivity Level: 1 (Unlimited) (maintained across all substitutes)

All five substitute parts from Bourns Inc. meet the primary compatibility criteria. Variations in secondary parameters such as melting I²t, DC cold resistance, and specific approval agencies do not preclude substitution when primary electrical and mechanical parameters align.

Engineering Selection Recommendations

SF-0603S250-2 (Bourns Inc.)

This substitute maintains 2.5 A at 32 V DC with 50 A breaking capacity and slow blow response. UL approval is provided. Operating temperature range is -20°C to 105°C, which is narrower than the original part. This substitute is suitable for applications where the operating environment remains within the specified temperature limits.

SF-0603S250M-2 (Bourns Inc.)

This substitute maintains 2.5 A at 32 V DC with slow blow response and extended operating temperature range of -55°C to 125°C. Breaking capacity is 35 A, which is lower than the original 50 A specification. No approval agency is listed. This substitute is suitable for applications where the reduced breaking capacity is acceptable and extended low-temperature operation is required.

SF-0603SA250M-2 (Bourns Inc.)

This substitute provides 2.5 A at 35 V DC (higher voltage rating than the original 32 V specification) with 50 A breaking capacity and slow blow response. Operating temperature range is -55°C to 150°C, matching the original part. cUL approval is provided. This substitute is suitable for applications requiring higher voltage margin and full temperature range operation.

SF-0603SP250-2 (Bourns Inc.)

This substitute maintains 2.5 A at 32 V DC with 50 A breaking capacity and slow blow response. UL approval is provided. Operating temperature range is -40°C to 105°C, which is narrower than the original part. This substitute is suitable for applications where the operating environment remains within the specified temperature limits.

SF-0603SP250M-2 (Bourns Inc.)

This substitute maintains 2.5 A at 32 V DC with 50 A breaking capacity and slow blow response. Operating temperature range is -55°C to 150°C, matching the original part. No approval agency is listed. This substitute is suitable for applications requiring full temperature range operation and equivalent electrical characteristics.

Frequently Asked Questions (FAQ)

Q: Can SF-0603S250M-2 be used as a direct replacement for 0ABB-2500-TM?

A: SF-0603S250M-2 is electrically compatible for current and voltage ratings. However, the breaking capacity is 35 A compared to the original 50 A. This substitute is acceptable only if the application circuit design does not require the higher breaking capacity specification.

Q: What is the difference between SF-0603SA250M-2 and other Bourns substitutes?

A: SF-0603SA250M-2 is rated for 35 V DC, which is 3 V higher than the original 32 V specification. All other electrical parameters (2.5 A current, slow blow response, 50 A breaking capacity) remain equivalent. The higher voltage rating provides additional safety margin in applications with voltage transients.

Q: Are all substitute parts compatible with the same PCB footprint?

A: All substitute parts use the 0603 (1608 Metric) package. However, physical dimensions vary slightly. SF-0603S250-2 and SF-0603SP250-2 have heights of 0.018" and unspecified height respectively, while SF-0603S250M-2, SF-0603SA250M-2, and SF-0603SP250M-2 have heights of 0.037", 0.031", and 0.031" respectively. PCB design must accommodate the maximum component height of the selected substitute.

Q: Which substitute has the broadest operating temperature range?

A: Both SF-0603SA250M-2 and SF-0603SP250M-2 provide the full operating temperature range of -55°C to 150°C, matching the original 0ABB-2500-TM specification.

Q: What approval agencies are represented across the substitute parts?

A: SF-0603S250-2 and SF-0603SP250-2 carry UL approval. SF-0603SA250M-2 carries cUL approval. SF-0603S250M-2 and SF-0603SP250M-2 do not list approval agencies. The original 0ABB-2500-TM carries AEC-Q200 and cURus approvals. Application requirements for specific certifications must be evaluated against substitute part certifications.

Q: Is RoHS compliance maintained across all substitutes?

A: Yes. The original 0ABB-2500-TM and all five substitute parts are ROHS3 Compliant. Moisture Sensitivity Level 1 (Unlimited) is maintained across all parts.

Q: Can SF-0603SP250M-2 be used in automotive applications?

A: SF-0603SP250M-2 does not list AEC-Q200 approval. The original 0ABB-2500-TM carries AEC-Q200 certification. If automotive qualification is required, SF-0603SP250M-2 is not suitable. Alternative substitutes with appropriate certifications must be selected based on application requirements.
