Key Parameters

Substitute Part Grouping Explanation

Substitution of the LR1F107K is permissible with parts that maintain identical electrical specifications across all critical parameters. The following parameters determine substitution eligibility:

• Resistance value: 107 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 (exact match required)
• Termination count: 2 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

Physical dimensions may vary within acceptable tolerances for through-hole axial components without affecting functional performance or circuit board layout compatibility.

Parameter Comparison

Engineering Selection Recommendations

The MRS25000C1073FCT00 manufactured by Vishay Beyschlag/Draloric/BC Components is a direct electrical equivalent to the LR1F107K. Both components satisfy identical electrical specifications and maintain ROHS3 compliance. The substitute part is suitable for applications where the LR1F107K is unavailable or when procurement from Vishay Beyschlag is preferred.

Physical dimension variations between the two parts are minor and do not impact through-hole circuit board mounting compatibility. The MRS25000C1073FCT00 is supplied in Cut Tape (CT) packaging format, whereas the LR1F107K is supplied in Tape & Box (TB) format. Both packaging formats are standard for axial resistor distribution and do not affect component performance or reliability.

Both parts carry identical ECCN and HTSUS classifications, confirming regulatory equivalence for export and trade purposes.

Frequently Asked Questions (FAQ)

Q: Can the MRS25000C1073FCT00 be used as a direct replacement for the LR1F107K in production assemblies?

A: Yes. Both components are electrically identical with matching resistance, tolerance, power rating, temperature coefficient, and operating temperature range. Both are ROHS3 compliant and carry identical regulatory classifications.

Q: Are there any dimensional compatibility concerns when substituting the MRS25000C1073FCT00 for the LR1F107K?

A: The MRS25000C1073FCT00 has slightly larger physical dimensions (0.098" Dia x 0.256" L versus 0.091" Dia x 0.244" L). These minor variations are within acceptable tolerances for through-hole axial component mounting and do not affect circuit board layout or component placement.

Q: What is the difference between Tape & Box (TB) and Cut Tape (CT) packaging?

A: Tape & Box packaging includes components wound on tape and supplied in a protective box, typically used for smaller order quantities. Cut Tape packaging supplies components on tape cut to specific lengths, commonly used for higher-volume orders. Both formats contain identical components and do not affect performance or reliability.

Q: Are both parts suitable for the full operating temperature range of -55°C to 155°C?

A: Yes. Both the LR1F107K and MRS25000C1073FCT00 are rated for continuous operation across the -55°C to 155°C temperature range with a temperature coefficient of ±50ppm/°C.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both components are ROHS3 compliant, carry identical ECCN (EAR99) and HTSUS (8533.21.0090) classifications, and meet equivalent environmental and trade regulations.
