Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LR1F453R is determined by matching the following critical parameters:

• Resistance Value: 453 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 0.6W (exact match required)
• Composition: Metal Film (exact match required)
• Package Type: Axial (exact match required)
• Temperature Coefficient: ±50ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

The MRS25000C4530FCT00 manufactured by Vishay Beyschlag/Draloric/BC Components meets all substitution criteria. Both parts are metal film axial resistors with identical electrical specifications, temperature performance, and regulatory compliance. Physical dimensions vary slightly within acceptable tolerances for through-hole applications.

Parameter Comparison

Engineering Selection Recommendations

Both the LR1F453R and MRS25000C4530FCT00 are active production components with full ROHS3 compliance and identical electrical performance specifications. Selection between these parts is based on procurement requirements and packaging format availability.

The LR1F453R is supplied in Tape & Box packaging, suitable for applications requiring bulk quantities with organized storage. The MRS25000C4530FCT00 is supplied in Cut Tape format, appropriate for automated assembly processes and component dispensing systems.

Physical dimensions differ marginally between the two parts. The MRS25000C4530FCT00 has a slightly larger diameter (0.098" versus 0.091") and length (0.256" versus 0.244"). These dimensional variations remain within acceptable tolerances for standard through-hole PCB layouts and do not affect electrical performance or thermal characteristics.

Both parts carry identical HTSUS classification (8533.21.0090) and ECCN designation (EAR99), ensuring equivalent regulatory treatment in procurement and export contexts.
