Substitute Part Grouping Explanation

Substitute parts for the 0ABB-8000-TM are identified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Current Rating: 8 A (exact match required)
• Package / Case: 0603 (1608 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Response Time: Slow Blow (exact match required)
• Fuse Type: Board Mount (Cartridge Style Excluded) (exact match required)
• Operating Temperature Range: -55°C ~ 150°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Secondary Compatibility Consideration:

• Voltage Rating - DC: Substitutes must equal or exceed the main part rating of 32 V DC

Two substitute parts meet these criteria: SF-0603SA800M-2 and SF-0603SP800M-2, both manufactured by Bourns Inc. The SF-0603SA800M-2 operates at 24 V DC, which is below the main part specification and represents a voltage-limited substitute. The SF-0603SP800M-2 operates at 32 V DC, matching the main part specification exactly.

Engineering Selection Recommendations

SF-0603SP800M-2 (Bourns Inc.) - Primary Substitute

The SF-0603SP800M-2 is the direct electrical and mechanical equivalent to the 0ABB-8000-TM. Both components share identical current rating (8 A), voltage rating (32 V DC), response time (Slow Blow), package specification (0603), and operating temperature range (-55°C ~ 150°C). Both maintain Active product status and ROHS3 compliance. The SF-0603SP800M-2 provides higher breaking capacity (80 A versus 50 A) and higher melting I²t (7 versus 4.5), representing enhanced performance characteristics. This substitute is suitable for direct replacement in applications requiring 32 V DC rated protection.

SF-0603SA800M-2 (Bourns Inc.) - Voltage-Limited Substitute

The SF-0603SA800M-2 matches all mechanical and thermal parameters of the main part but operates at 24 V DC maximum, compared to the 0ABB-8000-TM specification of 32 V DC. This substitute is applicable only in circuit designs where the actual operating voltage does not exceed 24 V DC. The SF-0603SA800M-2 provides higher breaking capacity (80 A) and lower melting I²t (2.727 versus 4.5). This component maintains Active product status and ROHS3 compliance. Selection of this substitute requires confirmation that circuit voltage requirements do not exceed the 24 V DC rating.

Frequently Asked Questions (FAQ)

Q: Can SF-0603SA800M-2 be used in place of 0ABB-8000-TM in all applications?

A: No. The SF-0603SA800M-2 is rated for 24 V DC maximum, while the 0ABB-8000-TM is rated for 32 V DC. The SF-0603SA800M-2 is suitable only for applications where the circuit voltage does not exceed 24 V DC. For circuits operating at voltages between 24 V DC and 32 V DC, the SF-0603SP800M-2 is the appropriate substitute.

Q: What is the difference between SF-0603SP800M-2 and SF-0603SA800M-2?

A: Both parts share identical current rating (8 A), package (0603), mounting type (Surface Mount), and response time (Slow Blow). The primary difference is voltage rating: SF-0603SP800M-2 is rated for 32 V DC, while SF-0603SA800M-2 is rated for 24 V DC. Additionally, the SF-0603SP800M-2 has higher melting I²t (7 versus 2.727).

Q: Are the physical dimensions of substitute parts identical to the main part?

A: The length (0.063" / 1.60mm) and width dimensions are identical across all three parts. The height dimension differs slightly: the main part 0ABB-8000-TM measures 0.019" H (0.48mm), while both Bourns substitutes measure 0.031" H (0.80mm). All parts conform to the 0603 (1608 Metric) package specification and are compatible with standard surface mount assembly processes.

Q: Do all parts meet the same compliance and regulatory requirements?

A: All three parts are ROHS3 Compliant and REACH Unaffected. The 0ABB-8000-TM carries AEC-Q200 and cURus approvals. The SF-0603SP800M-2 carries no listed approval agency designation. The SF-0603SA800M-2 carries cUL approval. Compliance requirements for specific applications should be verified against circuit design specifications.

Q: What is the significance of breaking capacity differences?

A: Breaking capacity indicates the maximum current the fuse can safely interrupt at its rated voltage. The 0ABB-8000-TM has a breaking capacity of 50 A at 32 V DC. Both Bourns substitutes have breaking capacity of 80 A, representing higher fault current handling capability. For applications with fault currents below 50 A, this difference is not operationally significant.

Q: Can these parts be used interchangeably in existing PCB designs?

A: The 0603 package specification ensures mechanical compatibility with existing PCB footprints. However, the slight height difference (0.019" versus 0.031") may affect solder joint formation and clearance to adjacent components. PCB layout review is necessary to confirm adequate clearance before substitution.
