LR1F487R Equivalent & Substitute Parts

Part Overview

The LR1F487R is a 487 Ohm ±1% 0.6W through-hole resistor manufactured by TE Connectivity Passive Product in the Neohm series. This axial metal film resistor is designed for general-purpose electronic applications requiring precision resistance values with tight tolerance specifications. The part is currently in active production status with 709 units available in stock. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when procurement requirements necessitate alternative manufacturers or packaging configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LR1F487R is permissible with parts that maintain identical electrical specifications across all critical parameters. The substitution logic is based on the following criteria:

Electrical Parameters (Must Match Exactly):

• Resistance value: 487 Ohms
• Tolerance: ±1%
• Power rating: 0.6W
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

• Package type: Axial
• Number of terminations: 2
• Composition: Metal Film

Compliance Parameters (Must Match):

• RoHS3 Compliant status

Parts meeting all these criteria are functionally equivalent and may be used interchangeably in circuit designs. Packaging format (Tape & Box versus Cut Tape) does not affect electrical or mechanical compatibility and represents a procurement distinction only.

Parameter Comparison

Engineering Selection Recommendations

The MRS25000C4870FC100 manufactured by Vishay Beyschlag/Draloric/BC Components is a direct electrical and mechanical equivalent to the LR1F487R. Both parts satisfy identical electrical specifications, operate across the same temperature range, and maintain ROHS3 compliance status.

Selection Basis:

The substitute part is suitable for direct replacement in applications where the LR1F487R is specified. Both parts are active production items with established supply availability. The MRS25000C4870FC100 currently maintains higher inventory levels (1755 units) compared to the primary part (709 units), providing enhanced procurement flexibility.

Physical dimensions exhibit minor variation within acceptable tolerances for axial through-hole resistor applications. The LR1F487R measures 2.30mm diameter by 6.20mm length, while the MRS25000C4870FC100 measures 2.50mm diameter by 6.50mm length. These dimensional differences do not affect electrical performance or standard PCB mounting compatibility for through-hole applications.

Packaging format differences (Tape & Box versus Cut Tape) represent procurement and handling distinctions only and do not impact circuit functionality or component performance.

Frequently Asked Questions (FAQ)

Q: Can the MRS25000C4870FC100 be used as a direct replacement for the LR1F487R in production assemblies?

A: Yes. The MRS25000C4870FC100 is electrically and mechanically equivalent to the LR1F487R. All critical parameters including resistance value, tolerance, power rating, temperature coefficient, and operating temperature range are identical. Both parts are ROHS3 compliant and feature identical axial package configuration with two terminations.

Q: Are there physical size differences between these parts?

A: Minor dimensional variation exists. The LR1F487R measures 2.30mm diameter by 6.20mm length, while the MRS25000C4870FC100 measures 2.50mm diameter by 6.50mm length. These differences fall within acceptable tolerances for standard through-hole PCB applications and do not affect mounting compatibility or circuit performance.

Q: What is the difference between Tape & Box and Cut Tape packaging?

A: Tape & Box (TB) and Cut Tape (CT) represent different packaging and delivery formats for the same component. Tape & Box includes a full reel of components on tape with a protective box. Cut Tape provides individual or partial quantities of components already cut from the reel. The electrical and mechanical properties of the component remain unchanged regardless of packaging format.

Q: Are both parts suitable for the same operating temperature applications?

A: Yes. Both the LR1F487R and MRS25000C4870FC100 operate across the identical temperature range of -55°C to 155°C with a temperature coefficient of ±50ppm/°C. They are suitable for equivalent thermal environments and applications.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant. The MRS25000C4870FC100 carries additional REACH Unaffected status. Both parts are classified under ECCN EAR99 and HTSUS 8533.21.0090 for regulatory and trade purposes.
