Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LR1F82R5 are qualified based on strict electrical and mechanical parameter matching within the through-hole axial resistor category. The following parameters determine substitution eligibility:

Critical Matching Parameters:

• Resistance value: 82.5 Ohms
• Tolerance: ±1%
• Power rating: 0.6W
• Composition: Metal Film
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Package configuration: Axial
• Number of terminations: 2
• RoHS compliance: ROHS3 Compliant

The substitute parts MRS25000C8259FCT00 and MRS25000C8259FRP00 from Vishay Beyschlag/Draloric/BC Components meet all critical electrical specifications. Both components are manufactured in the MRS25 series and maintain identical electrical performance characteristics. Physical dimensions vary slightly between the main part and substitutes due to different manufacturing standards, but both configurations are compatible with standard through-hole PCB layouts for axial resistors.

Parameter Comparison

Engineering Selection Recommendations

Both MRS25000C8259FCT00 and MRS25000C8259FRP00 are Active product status components from Vishay Beyschlag/Draloric/BC Components and maintain full ROHS3 compliance with REACH Unaffected status. These substitutes satisfy all electrical parameter requirements for direct replacement in applications requiring 82.5 Ohm ±1% 0.6W metal film axial resistors.

The primary distinction between the substitute parts is packaging format: MRS25000C8259FCT00 is supplied in Cut Tape format with 4813 pieces in stock, while MRS25000C8259FRP00 is also supplied in Cut Tape format with 10737 pieces in stock. Both substitute parts feature identical electrical specifications and operating characteristics.

Physical dimensions of the Vishay substitutes are marginally larger than the TE Connectivity LR1F82R5 (0.098" diameter and 0.256" length versus 0.091" diameter and 0.244" length). This dimensional difference remains within standard through-hole PCB design tolerances for axial resistor placement and does not affect electrical performance or thermal characteristics.

Frequently Asked Questions (FAQ)

Q: Can MRS25000C8259FCT00 and MRS25000C8259FRP00 be used interchangeably with LR1F82R5?

A: Yes. Both Vishay substitutes match all critical electrical parameters: 82.5 Ohm resistance, ±1% tolerance, 0.6W power rating, ±50ppm/°C temperature coefficient, and -55°C to 155°C operating range. Both are metal film axial resistors with identical electrical performance.

Q: What is the difference between MRS25000C8259FCT00 and MRS25000C8259FRP00?

A: Both parts are electrically identical. The difference is in packaging format designation and inventory availability. MRS25000C8259FCT00 is Cut Tape with 4813 units in stock. MRS25000C8259FRP00 is Cut Tape with 10737 units in stock. Both are suitable for production assembly.

Q: Are there physical dimension differences between the main part and substitutes?

A: Yes. The LR1F82R5 measures 0.091" diameter by 0.244" length. The Vishay substitutes measure 0.098" diameter by 0.256" length. These dimensional variations are within standard through-hole PCB design tolerances and do not affect circuit performance or thermal behavior.

Q: Do all three parts meet RoHS compliance requirements?

A: Yes. The LR1F82R5, MRS25000C8259FCT00, and MRS25000C8259FRP00 are all ROHS3 compliant. The Vishay substitutes additionally carry REACH Unaffected status.

Q: What is the temperature coefficient specification and how does it affect part selection?

A: All three parts specify ±50ppm/°C temperature coefficient. This parameter defines the resistor's resistance change per degree Celsius within the operating temperature range of -55°C to 155°C. Identical temperature coefficients ensure equivalent thermal stability across all three components.

Q: Can these parts be used in high-reliability applications?

A: All three components are Active product status with appropriate compliance certifications. Selection for high-reliability applications depends on specific application requirements beyond the electrical and mechanical parameters provided.
