Substitute Part Grouping Explanation

Substitute parts for the LR0204F20R are classified based on electrical and mechanical compatibility within the following criteria:

Upgrade Substitute (Higher Power Rating): SFR16S0002009FR500 maintains identical electrical specifications (20 Ohms, ±1% tolerance, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, metal film composition, axial package) while providing increased power dissipation capability at 0.5W (1/2W). This part is suitable for applications where the original 0.25W rating is insufficient but the same resistance and tolerance are required.

Similar Substitute (Identical Specifications): MFR-25FRF52-20R matches all critical electrical parameters of the LR0204F20R (20 Ohms, ±1% tolerance, 0.25W power rating, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, metal film composition, axial package) with dimensional variations in the physical form factor. This part is suitable for direct replacement in applications where the original specifications are maintained.

Both substitute parts are ROHS3 compliant, operate within the same temperature range, and maintain the same resistance tolerance and composition as the primary part.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (MFR-25FRF52-20R): This YAGEO part provides identical electrical specifications and power rating to the LR0204F20R. Both components are ROHS3 compliant, active in production, and maintain the same operating temperature range and tolerance. Selection of this part is appropriate when the original specifications must be preserved and dimensional variations are acceptable within the circuit layout constraints.

Upgrade Substitution (SFR16S0002009FR500): This Vishay part is suitable when circuit design permits increased power dissipation capability. The 0.5W rating provides additional thermal margin compared to the 0.25W primary part while maintaining identical resistance, tolerance, and temperature coefficient. This part is ROHS3 compliant and active in production. Selection is appropriate for applications requiring enhanced power handling without changing electrical performance characteristics.

All three parts maintain ROHS3 compliance and active production status, ensuring long-term availability and regulatory consistency.

Frequently Asked Questions (FAQ)

Q: Can SFR16S0002009FR500 be used as a direct replacement for LR0204F20R?

A: SFR16S0002009FR500 is electrically compatible with LR0204F20R as both maintain 20 Ohms resistance, ±1% tolerance, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. The primary difference is the increased power rating (0.5W versus 0.25W). This part is suitable for direct replacement in applications where the higher power rating does not create thermal or space constraints.

Q: What are the dimensional differences between these parts?

A: LR0204F20R measures 0.079" diameter × 0.138" length (2.00mm × 3.50mm). SFR16S0002009FR500 measures 0.075" diameter × 0.138" length (1.90mm × 3.50mm). MFR-25FRF52-20R measures 0.094" diameter × 0.248" length (2.40mm × 6.30mm). These variations may affect circuit board layout and component spacing considerations.

Q: Are all three parts ROHS3 compliant?

A: Yes, LR0204F20R, SFR16S0002009FR500, and MFR-25FRF52-20R are all ROHS3 compliant, ensuring regulatory consistency across substitute selections.

Q: What is the difference between the packaging formats?

A: LR0204F20R is supplied in Tape & Box (TB) format. SFR16S0002009FR500 and MFR-25FRF52-20R are supplied in Cut Tape (CT) format. Packaging format affects handling, storage, and automated assembly processes but does not impact electrical performance.

Q: Can MFR-25FRF52-20R replace LR0204F20R in all applications?

A: MFR-25FRF52-20R maintains identical electrical specifications and power rating as LR0204F20R. Compatibility depends on physical space constraints due to dimensional differences. The MFR part is longer (0.248" versus 0.138") and slightly wider in diameter (0.094" versus 0.079"), which may affect circuit board layout feasibility.

Q: What inventory levels are available for each part?

A: LR0204F20R has 871 pieces in stock. SFR16S0002009FR500 has 20808 pieces in stock. MFR-25FRF52-20R has 16451 pieces in stock. Higher inventory levels for substitute parts may support extended procurement timelines and supply chain continuity.
