LR1F82K5 Equivalent & Substitute Parts

Part Overview

The LR1F82K5 is an 82.5 kOhms ±1% 0.6W through-hole resistor manufactured by TE Connectivity Passive Product in the Neohm series. This axial metal film resistor operates across a temperature range of -55°C to 155°C with a temperature coefficient of ±50ppm/°C. The component is classified as Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility requirements are met for applications requiring alternative sourcing or inventory management.

The substitute parts MRS25000C8252FCT00 and MRS25000C8252FRP00 from Vishay Beyschlag/Draloric/BC Components meet all electrical specifications and mechanical requirements. Both parts are manufactured in the MRS25 series and maintain identical electrical performance characteristics. The primary distinction between these substitutes is packaging format: MRS25000C8252FCT00 is supplied in Cut Tape (CT) format, while MRS25000C8252FRP00 is also supplied in Cut Tape (CT) format.

Engineering Selection Recommendations

Both MRS25000C8252FCT00 and MRS25000C8252FRP00 are direct electrical and functional equivalents to the LR1F82K5. Selection between these options is determined by packaging and inventory requirements:

MRS25000C8252FCT00 is supplied in Cut Tape (CT) packaging with 10,911 pieces in stock inventory.

MRS25000C8252FRP00 is supplied in Cut Tape (CT) packaging with 2,033 pieces in stock inventory.

All three parts maintain Active product status and ROHS3 compliance. The Vishay substitutes feature slightly larger physical dimensions (0.098" diameter x 0.256" length versus 0.091" diameter x 0.244" length for the TE Connectivity original), which must be evaluated for board layout compatibility in space-constrained applications. Electrical performance, temperature stability, and reliability characteristics are equivalent across all three part numbers.

Frequently Asked Questions (FAQ)

Q: Can MRS25000C8252FCT00 or MRS25000C8252FRP00 be used as direct replacements for LR1F82K5?

A: Yes. Both Vishay parts are direct electrical equivalents with identical resistance value (82.5 kOhms), tolerance (±1%), power rating (0.6W), temperature coefficient (±50ppm/°C), and operating temperature range (-55°C ~ 155°C). Both are metal film axial resistors with two terminations and RoHS3 compliance.

Q: What is the difference between MRS25000C8252FCT00 and MRS25000C8252FRP00?

A: Both parts are electrically and mechanically identical. The designation difference reflects packaging format coding within the Vishay MRS25 series. Both are supplied in Cut Tape (CT) format. Selection between them is based on inventory availability and procurement requirements.

Q: Are there physical size differences between the LR1F82K5 and the Vishay substitutes?

A: Yes. The LR1F82K5 measures 0.091" diameter x 0.244" length (2.30mm x 6.20mm). The Vishay MRS25 parts measure 0.098" diameter x 0.256" length (2.50mm x 6.50mm). These dimensional differences must be evaluated for PCB layout compatibility, particularly in applications with tight spacing constraints.

Q: Are all three parts RoHS3 compliant?

A: Yes. The LR1F82K5, MRS25000C8252FCT00, and MRS25000C8252FRP00 are all RoHS3 compliant.

Q: What is the temperature coefficient specification, and is it identical across all three parts?

A: The temperature coefficient is ±50ppm/°C for all three parts. This specification defines the resistance change per degree Celsius across the operating temperature range and is identical for the TE Connectivity original and both Vishay substitutes.

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

A: Yes. All three parts are rated for operation across -55°C to 155°C, supporting both high-temperature and low-temperature applications within this range.
