Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 7010.9908.55 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Current Rating: 2 A
• Fuse Type: Board Mount (Cartridge Style Excluded)
• Mounting Type: Surface Mount
• Package / Case: 2-SMD, Square End Block
• Response Time: Fast Blow
• Size / Dimension: 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
• Manufacturer: SCHURTER Inc.
• Series: MKF

The substitute parts identified below maintain full compatibility with these parameters. The primary distinction between the main part and substitutes is the addition of specified voltage ratings and enhanced product status classification in the active alternatives.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts 7010.9908.57 and 7010.9908.03 provide direct functional equivalence to the obsolete 7010.9908.55 across all critical electrical and mechanical parameters. The selection between these two active alternatives is based on product status and compliance considerations:

7010.9908.57 is classified as an active product with current manufacturing support. This part carries ROHS3 compliance certification and REACH unaffected status, meeting contemporary regulatory requirements for electronic component procurement.

7010.9908.03 is also classified as an active product with equivalent electrical and mechanical specifications to 7010.9908.57. This part is supplied in bulk packaging and maintains identical ROHS3 compliance and REACH unaffected status.

Both substitute parts specify voltage ratings of 125 V AC and 125 V DC, with breaking capacity of 300 A and melting I²t of 0.72, providing enhanced specification documentation compared to the original obsolete part. Both maintain cURus approval agency certification consistent with the main part.

For new designs or production transitions, either 7010.9908.57 or 7010.9908.03 is suitable for direct replacement of 7010.9908.55, with packaging and supply chain considerations determining the optimal selection.

Frequently Asked Questions (FAQ)

Q: Can 7010.9908.57 or 7010.9908.03 be used as direct replacements for 7010.9908.55?
