Substitute Part Grouping Explanation

Substitution eligibility for the LR1F47K5 is determined by strict equivalence across the following critical parameters:

• Resistance Value: 47.5 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 0.6W (exact match required)
• Composition: Metal Film (exact match required)
• Temperature Coefficient: ±50ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• Package Configuration: Axial through-hole (exact match required)
• Regulatory Compliance: RoHS3 Compliant (exact match required)

The identified substitute part MRS25000C4752FRP00 meets all critical electrical and mechanical parameters. Physical dimensions vary slightly between manufacturers due to standard manufacturing tolerances, but both parts maintain identical electrical performance and functional compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the LR1F47K5 and MRS25000C4752FRP00 are active production parts with full RoHS3 compliance and REACH unaffected status. Selection between these parts is based on procurement and logistics requirements rather than electrical performance differences.

The LR1F47K5 is supplied in Tape & Box packaging, suitable for applications requiring organized component storage and manual assembly workflows. The MRS25000C4752FRP00 is supplied in Cut Tape format, optimized for automated pick-and-place assembly operations.

Physical dimensions differ slightly between manufacturers. The LR1F47K5 measures 0.091" diameter by 0.244" length, while the MRS25000C4752FRP00 measures 0.098" diameter by 0.256" length. Both dimensions remain within standard axial resistor form factors and are compatible with conventional through-hole PCB layouts. Component placement and spacing calculations should account for these minor dimensional variations.

Both parts carry identical electrical specifications and regulatory certifications, ensuring functional interchangeability in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can MRS25000C4752FRP00 be used as a direct replacement for LR1F47K5?

A: Yes. Both parts are electrically equivalent with identical resistance values (47.5 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 RoHS3 compliance.

Q: What are the physical dimension differences between these parts?

A: The LR1F47K5 measures 0.091" diameter by 0.244" length (2.30mm x 6.20mm). The MRS25000C4752FRP00 measures 0.098" diameter by 0.256" length (2.50mm x 6.50mm). These minor variations are within standard axial resistor tolerances and do not affect PCB compatibility for conventional through-hole layouts.

Q: Are there packaging differences between these parts?

A: Yes. The LR1F47K5 is supplied in Tape & Box (TB) packaging, while the MRS25000C4752FRP00 is supplied in Cut Tape (CT) format. Tape & Box packaging is suitable for manual assembly and organized storage. Cut Tape format is optimized for automated assembly equipment.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the LR1F47K5 and MRS25000C4752FRP00 are RoHS3 compliant. The MRS25000C4752FRP00 carries REACH Unaffected status, while the LR1F47K5 lists REACH status as Vendor Undefined. Both parts carry EAR99 ECCN classification.

Q: What is the temperature coefficient specification and why does it matter?

A: Both parts have a temperature coefficient of ±50ppm/°C, meaning the resistance value changes by a maximum of 50 parts per million for each degree Celsius change in operating temperature. This specification is critical for precision analog circuits and measurement applications where temperature stability is required.

Q: Can these parts be used interchangeably in automated assembly?

A: Both parts are compatible with automated assembly equipment. The MRS25000C4752FRP00 in Cut Tape format is optimized for pick-and-place machinery. The LR1F47K5 in Tape & Box format requires manual feeding or custom feeder adaptation for automated lines.
