Key Parameters

Substitute Part Grouping Explanation

Substitution of the LR1F11K8 is determined by strict equivalence across the following electrical and mechanical parameters:

• Resistance Value: 11.8 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 0.6W (exact match required)
• Composition: Metal Film (exact match required)
• Temperature Coefficient: ±50ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• Package Configuration: Axial through-hole (exact match required)
• Termination Count: 2 (exact match required)
• Compliance: RoHS3 Compliant (exact match required)

The identified substitute part meets all these criteria and is therefore electrically and mechanically interchangeable within the specified operating conditions.

Parameter Comparison

Engineering Selection Recommendations

Both the LR1F11K8 and MRS25000C1182FCT00 are Active product status components with full RoHS3 compliance. Selection between these parts is based on availability, packaging format, and physical dimensions.

The LR1F11K8 is supplied in Tape & Box (TB) packaging with dimensions of 0.091" diameter by 0.244" length. The MRS25000C1182FCT00 is supplied in Cut Tape (CT) packaging with slightly larger dimensions of 0.098" diameter by 0.256" length. Both components are electrically identical across all specified parameters.

Physical dimension differences are minor and do not affect electrical performance. Component selection should account for PCB layout constraints, automated assembly equipment compatibility, and packaging requirements for your specific application.

Frequently Asked Questions (FAQ)
