Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMF553M0100GLEA is determined by the following critical parameters:

• Resistance value: 3.01 MOhms (exact match required)
• Power rating: 0.5W minimum (equal or higher acceptable)
• Package type: Axial through-hole (mechanical compatibility)
• Operating temperature range: -55°C to 175°C minimum (equal or wider acceptable)
• Composition: Metal film (electrical performance consistency)
• Physical dimensions: 0.090" Dia x 0.240" L (mechanical fit requirement)

Tolerance may vary within acceptable limits for the application. Packaging format (Tape & Reel vs. Cut Tape) does not affect electrical or mechanical substitution eligibility. Compliance certifications (RoHS3, REACH status) are application-dependent considerations.

Parameter Comparison

Engineering Selection Recommendations

The CMF553M0100FHEB qualifies as a direct substitute for the CMF553M0100GLEA based on matching resistance value, power rating, physical dimensions, and operating temperature range. Both components are manufactured by Vishay Dale within the CMF series and maintain ROHS3 compliance.

The CMF553M0100FHEB offers improved tolerance specification (±1% versus ±2%) and superior temperature coefficient performance (±50ppm/°C versus ±150ppm/°C), making it suitable for applications requiring tighter resistance accuracy and enhanced thermal stability. The substitute part is available in Cut Tape packaging format versus Tape & Reel for the main part; packaging selection depends on assembly process requirements.

Both components are classified as Active products with current inventory availability. Selection between these parts should be based on tolerance requirements, temperature coefficient performance needs, and packaging format compatibility with production processes.

Frequently Asked Questions (FAQ)

Q: Can CMF553M0100FHEB replace CMF553M0100GLEA in existing designs?

A: Yes. Both parts share identical resistance value (3.01 MOhms), power rating (0.5W), physical dimensions (0.090" Dia x 0.240" L), and operating temperature range (-55°C to 175°C). Mechanical and electrical compatibility is maintained. The substitute offers tighter tolerance (±1% vs. ±2%) and lower temperature coefficient (±50ppm/°C vs. ±150ppm/°C).

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

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, suitable for automated pick-and-place assembly. Cut Tape (CT) packaging provides components on tape segments cut to specified lengths, suitable for manual assembly or smaller production runs. Electrical and mechanical properties are identical; selection depends on assembly equipment and volume requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both CMF553M0100GLEA and CMF553M0100FHEB are ROHS3 compliant, meeting European Union Restriction of Hazardous Substances regulations.

Q: What does temperature coefficient mean in resistor selection?

A: Temperature coefficient (ppm/°C) specifies the fractional change in resistance per degree Celsius change in operating temperature. CMF553M0100FHEB exhibits ±50ppm/°C compared to ±150ppm/°C for CMF553M0100GLEA, indicating superior resistance stability across temperature variations. Lower temperature coefficient values are preferred for precision applications.

Q: Can I use the substitute in high-precision measurement circuits?

A: The CMF553M0100FHEB is better suited for high-precision applications due to its ±1% tolerance and ±50ppm/°C temperature coefficient. The main part (CMF553M0100GLEA) with ±2% tolerance and ±150ppm/°C coefficient is suitable for general-purpose applications where tighter specifications are not required.
