LR1F24R Equivalent & Substitute Parts

Part Overview

The LR1F24R is a 24 Ohm, ±1% tolerance, 0.6W through-hole axial metal film resistor manufactured by TE Connectivity Passive Product. This component is classified as Active product status and is ROHS3 compliant. Substitute parts are identified when inventory availability is limited, when specific packaging formats are required for manufacturing processes, or when alternative suppliers must be qualified for supply chain continuity.

Substitute Part Grouping Explanation

Substitution of the LR1F24R is permissible when the following parameters are maintained across all candidate parts:

Resistance value of 24 Ohms
Tolerance of ±1%
Power rating of 0.6W
Metal film composition
Axial through-hole package configuration
Temperature coefficient of ±50ppm/°C
Operating temperature range of -55°C to 155°C
Two terminations
ROHS3 compliance status

The identified substitute part MRS25000C2409FCT00 satisfies all critical electrical and mechanical parameters. Dimensional variations within the axial package category do not affect functional performance in standard circuit applications. Packaging format differences (Tape & Box versus Cut Tape) reflect manufacturing and logistics considerations rather than component performance differences.

Engineering Selection Recommendations

Both the LR1F24R and MRS25000C2409FCT00 are Active product status components with ROHS3 compliance and identical electrical specifications. Selection between these parts should be based on the following criteria:

LR1F24R (TE Connectivity): Select this part when Tape & Box packaging is required for automated assembly processes or when TE Connectivity supply chain qualification is mandated by design specifications.

MRS25000C2409FCT00 (Vishay Beyschlag): Select this part when Cut Tape packaging is compatible with manufacturing equipment, when Vishay Beyschlag supplier qualification is established, or when inventory availability from this manufacturer is prioritized.

Both parts carry identical ECCN (EAR99) and HTSUS (8533.21.0090) classifications, indicating equivalent regulatory treatment for export and tariff purposes. The dimensional differences between the two axial packages fall within standard manufacturing tolerances for this component category and do not affect electrical performance or circuit board layout compatibility in standard applications.

Frequently Asked Questions (FAQ)

Q: Can MRS25000C2409FCT00 be used as a direct replacement for LR1F24R in all applications?

A: Yes. Both parts meet identical electrical specifications: 24 Ohms ±1% tolerance, 0.6W power rating, metal film composition, ±50ppm/°C temperature coefficient, and -55°C to 155°C operating range. Both are ROHS3 compliant and carry Active product status.

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

A: Tape & Box packaging supplies components on continuous tape with a protective box for storage and handling. Cut Tape packaging supplies components on tape segments cut to specific lengths. These are logistics and manufacturing format differences. The components themselves are electrically and mechanically identical.

Q: Are the dimensional differences between LR1F24R and MRS25000C2409FCT00 significant?

A: No. The LR1F24R measures 0.091" diameter × 0.244" length, while the MRS25000C2409FCT00 measures 0.098" diameter × 0.256" length. Both are axial through-hole components, and these dimensional variations fall within standard manufacturing tolerances for this package category. They are functionally interchangeable in standard circuit board layouts.

Q: Do both parts have the same compliance certifications?

A: Yes. Both parts are ROHS3 compliant, carry EAR99 ECCN classification, and share the same HTSUS code (8533.21.0090). Both have Not Applicable moisture sensitivity levels.

Q: What parameters must remain identical for substitution to be valid?

A: Resistance value (24 Ohms), tolerance (±1%), power rating (0.6W), composition (metal film), temperature coefficient (±50ppm/°C), operating temperature range (-55°C to 155°C), package type (axial), and number of terminations (2) must all remain identical. RoHS compliance status must also match.
