Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCHURTER 7010.9910.55 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Current Rating: 3 A
• Response Time: Fast Blow
• Mounting Type: Surface Mount
• Fuse Type: Board Mount (Cartridge Style Excluded)
• Package / Case: 2-SMD, Square End Block
• Physical Dimensions: 0.276" L x 0.100" W x 0.100" H (7.00mm x 2.54mm x 2.54mm)
• Operating Temperature Range: -55°C ~ 85°C
• Approval Agency: cURus

The SCHURTER 7010.9910.57 meets all critical parameters and is classified as an active product within the same MKF series. This part provides voltage ratings (125 V AC / 125 V DC) and additional performance specifications not present in the obsolete reference part, making it a direct functional equivalent for board-level fuse protection applications.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 7010.9910.57 is the appropriate substitute for the obsolete SCHURTER 7010.9910.55. Both components share identical electrical ratings (3 A fast-blow), mechanical form factor (2-SMD, square end block), and thermal operating range (-55°C to 85°C). Both components carry cURus approval certification, ensuring regulatory compliance in equivalent applications.

The 7010.9910.57 is an active product with current manufacturing support and inventory availability. The substitute part provides explicit voltage ratings (125 V AC / 125 V DC) and additional performance data (300 A breaking capacity, 1.3 melting I²t) that enhance design documentation and circuit protection verification. The substitute part is ROHS3 compliant and REACH unaffected, meeting modern environmental and regulatory requirements.

Direct PCB footprint compatibility is confirmed through identical physical dimensions and package configuration. No circuit redesign, layout modification, or requalification is required for substitution in existing applications.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 7010.9910.57 be used as a direct replacement for the 7010.9910.55 on existing PCBs?

A: Yes. Both parts share identical physical dimensions (0.276" L x 0.100" W x 0.100" H), package configuration (2-SMD, square end block), and mounting type (surface mount). PCB footprints are directly compatible without modification.

Q: What is the voltage rating difference between these two parts?

A: The 7010.9910.55 does not specify voltage ratings in its technical documentation. The 7010.9910.57 is rated for 125 V AC and 125 V DC operation. Both parts are suitable for general-purpose board-level fuse protection across standard industrial and consumer voltage levels.

Q: Are both parts certified by the same approval agency?

A: Yes. Both the 7010.9910.55 and 7010.9910.57 carry cURus approval certification, confirming compliance with North American electrical safety standards.

Q: What is the significance of the 7010.9910.57 being ROHS3 compliant?

A: ROHS3 compliance indicates the substitute part meets current European Union restrictions on hazardous substances. This certification is relevant for products sold in EU markets and for organizations with environmental compliance requirements. The original part does not specify RoHS status.

Q: Is the 3 A current rating identical between both parts?

A: Yes. Both the 7010.9910.55 and 7010.9910.57 are rated for 3 A continuous current with fast-blow response characteristics. Current protection levels are equivalent.

Q: What does "fast-blow" response time mean?

A: Fast-blow fuses interrupt circuit current rapidly when overcurrent conditions occur, typically within milliseconds. This response characteristic is identical in both parts and is suitable for protecting sensitive electronic circuits and components.

Q: Why is the 7010.9910.55 classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. The SCHURTER 7010.9910.57 represents the current active equivalent within the MKF series, ensuring ongoing availability and manufacturing support.
