LR0204F20K Equivalent & Substitute Parts

Part Overview

The LR0204F20K is a 20 kOhms ±1% 0.25W axial metal film through-hole resistor manufactured by TE Connectivity Passive Product. This component is classified as Active product status and is ROHS3 compliant. Substitute parts are identified when original stock becomes unavailable, when alternative packaging formats are required, or when higher power ratings are necessary for circuit redesign applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LR0204F20K are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Resistance value: 20 kOhms
• Tolerance: ±1%
• Composition: Metal Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Package Type: Axial
• Number of Terminations: 2
• RoHS Compliance: ROHS3 Compliant

Allowable Variation Parameters:

• Power Rating: Equal or greater than 0.25W
• Packaging Format: Tape & Box or Cut Tape
• Physical Dimensions: Variations permitted within axial package constraints

Two substitute parts meet these criteria: the SFR16S0002002FR500 (upgrade with higher power rating) and the MFR-25FRF52-20K (equivalent specification with alternative packaging).

Parameter Comparison

Engineering Selection Recommendations

LR0204F20K (Original): Select this part when TE Connectivity Passive Product components are specified in design documentation or when Tape & Box packaging is required for automated assembly processes. Product status is Active with established supply chain availability.

SFR16S0002002FR500 (Upgrade Substitute): This Vishay Beyschlag/Draloric/BC Components part provides identical electrical specifications with doubled power rating (0.5W versus 0.25W). Select this part when circuit redesign permits higher power dissipation capability or when thermal margin improvement is required. Physical dimensions are slightly smaller in diameter. Packaging format is Cut Tape. Product status is Active.

MFR-25FRF52-20K (Similar Substitute): This YAGEO part matches the original specification exactly in resistance, tolerance, power rating, and temperature coefficient. Select this part when YAGEO component qualification is required or when Cut Tape packaging is preferred. Physical dimensions are larger in both diameter and length. Product status is Active.

All three parts maintain ROHS3 compliance, REACH Unaffected status, and EAR99 export classification. Selection between substitutes depends on packaging format requirements, physical space constraints, and manufacturer qualification specifications.

Frequently Asked Questions (FAQ)

Q: Can the SFR16S0002002FR500 directly replace the LR0204F20K in all applications?

A: The SFR16S0002002FR500 is electrically compatible as a direct substitute. It provides identical resistance, tolerance, temperature coefficient, and operating temperature range. The higher power rating (0.5W versus 0.25W) is a non-limiting upgrade. Physical dimensions differ slightly; verify PCB layout clearances before substitution. Packaging format differs (Cut Tape versus Tape & Box).

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

A: The LR0204F20K measures 0.079" diameter × 0.138" length. The SFR16S0002002FR500 measures 0.075" diameter × 0.138" length (slightly smaller diameter, same length). The MFR-25FRF52-20K measures 0.094" diameter × 0.248" length (larger in both dimensions). Verify PCB hole spacing and component clearance before selecting the MFR-25FRF52-20K.

Q: Are all three parts ROHS3 compliant?

A: Yes. The LR0204F20K, SFR16S0002002FR500, and MFR-25FRF52-20K are all ROHS3 compliant and REACH Unaffected. All three carry EAR99 export classification and share the same HTSUS code (8533.21.0090).

Q: What is the difference between Tape & Box and Cut Tape packaging?

A: Tape & Box packaging (TB) includes a protective box and is suitable for manual handling and smaller quantity orders. Cut Tape (CT) packaging is supplied on continuous tape and is optimized for automated pick-and-place assembly equipment. Both formats contain the same component; packaging selection depends on assembly process requirements.

Q: Can I use the MFR-25FRF52-20K if space is limited on my PCB?

A: No. The MFR-25FRF52-20K is larger than the original LR0204F20K in both diameter and length. If PCB space is constrained, the SFR16S0002002FR500 is the better choice as it has a slightly smaller diameter while maintaining the same axial length.

Q: Are the temperature coefficients identical across all three parts?

A: Yes. All three parts specify ±100ppm/°C temperature coefficient and operate across the identical temperature range of -55°C to 155°C.
