Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LR0204F15R are identified based on strict equivalence of the following critical parameters:

• Resistance Value: 15 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 0.25W / 1/4W (exact match required)
• Composition: Metal Film (exact match required)
• Package Configuration: Axial through-hole (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C to 155°C (exact match required)
• Compliance: ROHS3 Compliant (exact match required)

Substitute parts must satisfy all electrical and mechanical parameters listed above. Physical dimensions may vary within the axial package category while maintaining functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both the LR0204F15R and MFR-25FRF52-15R meet the electrical and compliance requirements for 15 Ohm, ±1% tolerance, 1/4W metal film axial resistors. Both components are ROHS3 compliant and operate across the -55°C to 155°C temperature range with identical temperature coefficients.

The primary distinction between these parts is physical dimension and packaging format. The LR0204F15R features a more compact axial profile (2.00mm diameter x 3.50mm length) and is supplied in Tape & Box packaging. The MFR-25FRF52-15R has a larger axial profile (2.40mm diameter x 6.30mm length) and is supplied in Cut Tape packaging.

Selection between these parts depends on circuit board layout constraints and procurement requirements. Both components are active products with established supply availability.

Frequently Asked Questions (FAQ)

Q: Can the MFR-25FRF52-15R replace the LR0204F15R in all applications?

A: The MFR-25FRF52-15R is electrically equivalent to the LR0204F15R. Both components share identical resistance, tolerance, power rating, temperature coefficient, and operating temperature specifications. Physical dimensions differ; the MFR-25FRF52-15R is larger. Substitution is valid when circuit board layout accommodates the larger axial package dimensions.

Q: What are the key electrical parameters that must match for substitution?

A: Substitution requires exact equivalence in resistance value (15 Ohms), tolerance (±1%), power rating (0.25W), composition (metal film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C).

Q: Are there packaging considerations when substituting these parts?

A: Yes. The LR0204F15R is supplied in Tape & Box format, while the MFR-25FRF52-15R is supplied in Cut Tape format. Additionally, the MFR-25FRF52-15R has larger physical dimensions. Verify that procurement and assembly processes accommodate the different packaging and that circuit board layout permits the larger component size.

Q: Do both parts meet the same compliance standards?

A: Both the LR0204F15R and MFR-25FRF52-15R are ROHS3 compliant. Both carry the same ECCN classification (EAR99) and HTSUS code (8533.21.0090).

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

A: Both parts have a temperature coefficient of ±100ppm/°C. This specification defines the maximum change in resistance value per degree Celsius of temperature change. Identical temperature coefficients ensure equivalent performance across the operating temperature range.
