CMF5575K000FEEK Equivalent & Substitute Parts

Part Overview

The CMF5575K000FEEK is a 75 kOhm ±1% metal film through-hole resistor rated at 0.5W (1/2W) in axial package configuration, manufactured by Vishay Dale. This component is designed for applications requiring precision resistance with flame retardant coating and moisture resistance in a compact axial form factor. The part is currently active in production and widely available in inventory.

Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits selection from qualified alternatives that meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMF5575K000FEEK is determined by the following critical parameters:

• Resistance Value: Must be 75 kOhms
• Tolerance: Must be ±1% or tighter
• Composition: Metal film construction required
• Package: Axial through-hole configuration
• Power Rating: Minimum 0.5W capability
• Operating Temperature: Must support -55°C to 175°C range
• Compliance: ROHS3 compliance required

The substitute part MFR-25FBF52-75K meets the core electrical specifications (75 kOhms, ±1%, metal film, axial package, ROHS3 compliant). However, this substitute operates at a reduced power rating of 0.25W (1/4W) and has a narrower maximum operating temperature of 155°C, which may limit its use in high-temperature or high-power dissipation applications.

Parameter Comparison

Engineering Selection Recommendations

Selection between CMF5575K000FEEK and MFR-25FBF52-75K is based on application requirements and compliance constraints:

CMF5575K000FEEK is the primary choice for applications requiring:

• Power dissipation up to 0.5W
• Operating temperatures above 155°C (up to 175°C maximum)
• Superior temperature stability (±25ppm/°C vs ±100ppm/°C)
• Flame retardant and moisture-resistant coating specifications

MFR-25FBF52-75K is suitable as a substitute when:

• Power dissipation does not exceed 0.25W
• Operating temperature remains below 155°C
• ROHS3 compliance is required
• Component availability or supply chain considerations necessitate alternative sourcing

Both parts maintain ROHS3 compliance and identical resistance and tolerance specifications. Physical dimensions are comparable with minimal variation in axial package form factor.

Frequently Asked Questions (FAQ)

Q: Can MFR-25FBF52-75K replace CMF5575K000FEEK in all applications?

A: No. The substitute part has a lower power rating (0.25W vs 0.5W) and reduced maximum operating temperature (155°C vs 175°C). Substitution is valid only when circuit power dissipation remains below 0.25W and operating temperature does not exceed 155°C.

Q: What is the significance of the temperature coefficient difference?

A: The CMF5575K000FEEK has a temperature coefficient of ±25ppm/°C, while MFR-25FBF52-75K is ±100ppm/°C. This means the substitute part's resistance value will drift more significantly across temperature variations. For precision applications requiring tight tolerance maintenance across temperature ranges, the main part is preferred.

Q: Are the physical dimensions compatible for PCB layout?

A: Both parts use axial package configuration with similar dimensions. CMF5575K000FEEK is 0.090" diameter x 0.240" length; MFR-25FBF52-75K is 0.094" diameter x 0.248" length. The minor dimensional difference is negligible for standard through-hole PCB layouts.

Q: Do both parts meet the same compliance standards?

A: Both CMF5575K000FEEK and MFR-25FBF52-75K are ROHS3 compliant. Both carry EAR99 ECCN classification and fall under HTSUS code 8533.21.0090.

Q: What happens if I use the substitute in a high-temperature application?

A: Operating the MFR-25FBF52-75K above 155°C exceeds its maximum rated temperature and will result in component degradation, potential failure, and unpredictable resistance drift. The CMF5575K000FEEK is rated to 175°C and is the correct choice for such applications.
