Key Parameters

Substitute Part Grouping Explanation

Substitution between the 0881060.URF and 0881060.UR is determined by strict equivalence across the following critical parameters:

• Current Rating: Both parts rated at 60 A
• Voltage Rating (DC): Both rated at 75 V
• Mounting Type: Both are surface mount
• Package Configuration: Both use 2-SMD, J-Lead package
• Breaking Capacity: Both rated at 1.5 kA @ rated voltage
• Melting I²t: Both have melting I²t of 1050
• Operating Temperature: Both operate across -55°C to 100°C
• Regulatory Compliance: Both are ROHS3 compliant and cURus approved

The 0881060.UR is the manufacturer-recommended active production equivalent, differing only in packaging format (Cut Tape & Digi-Reel vs. standard packaging) and minor dimensional notation variance that does not affect functional or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 0881060.UR is the direct active production substitute for the obsolete 0881060.URF. Both components meet identical electrical and mechanical specifications, including current rating, voltage rating, breaking capacity, and thermal operating range. Both carry cURus approval and ROHS3 compliance certification.

Selection of the 0881060.UR is supported by:

• Product Status: Active production status ensures ongoing availability and manufacturer support
• Regulatory Compliance: Maintains cURus approval and ROHS3 compliance equivalent to the original part
• Electrical Equivalence: Identical current, voltage, and breaking capacity ratings
• Mechanical Compatibility: Identical package configuration (2-SMD, J-Lead) and mounting type (surface mount)
• Thermal Performance: Identical operating temperature range (-55°C to 100°C)

Frequently Asked Questions (FAQ)

Q: Can the 0881060.UR be used as a direct replacement for the 0881060.URF in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters: 60A current rating, 75V DC voltage rating, 1.5kA breaking capacity, 2-SMD J-Lead package, and identical operating temperature range. The primary difference is product status (active vs. obsolete) and packaging format.

Q: What is the difference between the 0881060.URF and 0881060.UR?

A: The 0881060.UR is the active production equivalent. Both parts share identical electrical specifications and package configuration. The 0881060.UR is available in Cut Tape and Digi-Reel packaging formats, while the 0881060.URF is obsolete. Functional performance and board-level compatibility are equivalent.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical regulatory certifications: cURus approval and ROHS3 compliance. Both have MSL rating of 1 (Unlimited).

Q: What packaging formats are available for the substitute part?

A: The 0881060.UR is available in Cut Tape (CT) and Digi-Reel packaging formats, providing flexibility for both manual and automated assembly processes.

Q: Is the DC cold resistance specification identical between both parts?

A: The DC cold resistance is functionally equivalent: 0881060.URF is specified as 0.81 Ohms, while 0881060.UR is specified as 81 mOhms (0.081 Ohms). This represents a notation difference; both values are within equivalent operating parameters for this component class.
