Key Parameters

Substitute Part Grouping Explanation

Substitution for the MMF204FRE4R75 is determined by strict equivalence in the following parameters:

• Resistance value: 4.75 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Composition: Metal Film (exact match required)
• Package / Case: MELF, 0204 (exact match required)
• Physical dimensions: 0.055" Dia x 0.138" L (exact match required)
• Temperature Coefficient: ±50ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• RoHS and REACH compliance status (exact match required)

The power rating may vary within the MELF 0204 package format while maintaining all other electrical and mechanical specifications. Substitute parts must be from the same series (MMF) and maintain active product status.

Parameter Comparison

Engineering Selection Recommendations

Both the MMF204FRE4R75 and MMF25SFRE4R75 maintain identical electrical characteristics, mechanical compatibility, and regulatory compliance. Selection between these parts is based on power dissipation requirements within the circuit application. The MMF204FRE4R75 provides 0.4W power handling, while the MMF25SFRE4R75 provides 0.25W power handling. Both parts are manufactured by YAGEO, carry active product status, and meet ROHS3 and REACH compliance requirements. Inventory availability may influence component selection in production environments.

Frequently Asked Questions (FAQ)

Q: Can MMF25SFRE4R75 replace MMF204FRE4R75 in all applications?

A: Substitution is valid only when the circuit application requires 0.25W or less power dissipation. The MMF25SFRE4R75 has a lower power rating (0.25W) compared to the MMF204FRE4R75 (0.4W). If the application requires power dissipation exceeding 0.25W, the MMF204FRE4R75 must be used.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts use the MELF 0204 package with identical dimensions of 0.055" Dia x 0.138" L (1.40mm x 3.50mm). They are mechanically interchangeable on PCB layouts.

Q: Do both parts meet the same compliance standards?

A: Yes. Both MMF204FRE4R75 and MMF25SFRE4R75 are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating.

Q: What is the temperature coefficient difference between these parts?

A: Both parts have identical temperature coefficients of ±50ppm/°C and operate across the same temperature range of -55°C to 155°C.

Q: Are there any differences in tolerance or resistance value?

A: No. Both parts are rated at 4.75 Ohms with ±1% tolerance. Electrical performance is identical in terms of resistance accuracy.
