Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LR0204F75K are classified based on electrical and mechanical compatibility within the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 75 kOhms
• Tolerance: ±1%
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Composition: Metal Film
• Number of terminations: 2

Mechanical Parameters (Must Match):

• Package type: Axial
• Through-hole configuration

Allowable Variations:

• Power rating: May be equal to or greater than 0.25W
• Physical dimensions: May vary within axial package constraints
• Packaging format: Tape & Box or Cut Tape acceptable
• Manufacturer: Different manufacturers permitted

Upgrade Classification: The SFR16S0007502FR500 is classified as an upgrade substitute due to its higher power rating (0.5W vs. 0.25W) while maintaining all other electrical specifications.

Similar Classification: The MFR-25FRF52-75K is classified as a similar substitute, matching the original power rating (0.25W) and all electrical specifications with dimensional variations within acceptable axial package tolerances.

Parameter Comparison

Engineering Selection Recommendations

LR0204F75K (Primary Part) Select this part when the original specification is required and availability permits. The part is active in production with adequate stock levels (996 pieces). ROHS3 compliance is confirmed.

SFR16S0007502FR500 (Upgrade Substitute) This part is suitable for applications where increased power dissipation capability is beneficial or required. The upgrade from 0.25W to 0.5W power rating provides additional thermal margin without altering electrical performance. All electrical parameters remain identical. The part is active in production with high stock availability (35,597 pieces). ROHS3 compliance is confirmed and REACH status is unaffected. Physical dimensions are slightly smaller in diameter (0.075" vs. 0.079"), which may improve board layout in space-constrained designs. Packaging is Cut Tape format.

MFR-25FRF52-75K (Similar Substitute) This part maintains the original 0.25W power rating and all electrical specifications. Selection is appropriate when the original part is unavailable and equivalent specifications are required. The part is active in production with good stock availability (7,167 pieces). ROHS3 compliance is confirmed and REACH status is unaffected. Physical dimensions are larger (0.094" Dia x 0.248" L), which requires verification of board layout compatibility. Packaging is Cut Tape format.

All three parts share identical electrical performance characteristics, operating temperature range, and regulatory compliance status. Selection between them depends on power dissipation requirements, physical space constraints, and packaging format preferences.

Frequently Asked Questions (FAQ)

Q: Can SFR16S0007502FR500 be used as a direct replacement for LR0204F75K? A: Yes. The SFR16S0007502FR500 is electrically equivalent with identical resistance, tolerance, temperature coefficient, and operating temperature range. The higher power rating (0.5W vs. 0.25W) is a non-limiting upgrade. Physical dimensions differ slightly but remain within axial package standards. Verify board layout clearance before substitution.

Q: What is the difference between the upgrade and similar substitute classifications? A: The SFR16S0007502FR500 is classified as an upgrade because its power rating exceeds the original specification (0.5W vs. 0.25W), providing additional thermal capability. The MFR-25FRF52-75K is classified as similar because it matches the original power rating (0.25W) and all electrical specifications. Both are electrically compatible.

Q: Are there any compliance or regulatory differences between the three parts? A: All three parts are ROHS3 compliant and share the same ECCN (EAR99) and HTSUS (8533.21.0090) classifications. The SFR16S0007502FR500 and MFR-25FRF52-75K have confirmed REACH unaffected status, while the LR0204F75K shows vendor undefined REACH status. This does not prevent substitution but should be noted for regulatory documentation purposes.

Q: Do the physical dimension differences affect circuit performance? A: No. Physical dimensions do not affect electrical performance. However, dimensional differences may impact board layout, PCB routing, and component spacing. The MFR-25FRF52-75K is notably longer (0.248" vs. 0.138"), requiring verification of available board space. The SFR16S0007502FR500 is slightly smaller in diameter, which may improve layout flexibility.

Q: Which substitute part has the best stock availability? A: The SFR16S0007502FR500 has the highest stock level at 35,597 pieces. The MFR-25FRF52-75K has 7,167 pieces available. The original LR0204F75K has 996 pieces in stock.

Q: Can these parts be used interchangeably in existing designs without modification? A: Electrical interchangeability is confirmed for all three parts. Physical interchangeability requires verification of board layout constraints, particularly for the MFR-25FRF52-75K due to its increased length. No circuit modifications are required when substituting between these parts.

Q: What packaging formats are available for each part? A: The LR0204F75K is supplied in Tape & Box (TB) format. Both substitute parts (SFR16S0007502FR500 and MFR-25FRF52-75K) are supplied in Cut Tape (CT) format. Packaging format selection depends on assembly process requirements and inventory management preferences.
