Key Parameters

Substitute Part Grouping Explanation

The CMF55100R00BEEB from Vishay Dale qualifies as a substitute based on the following matching electrical and mechanical parameters:

• Resistance value: 100 Ohms (identical)
• Tolerance: ±0.1% (identical)
• Composition: Metal Film (identical)
• Package: Axial (identical)
• Temperature Coefficient: ±25ppm/°C (identical)
• RoHS3 Compliance: Yes (identical)
• REACH Status: REACH Unaffected (identical)

The substitute part exceeds the main part specification in power rating (0.5W vs 0.25W) and operating temperature range (-55°C ~ 175°C vs -55°C ~ 155°C), making it suitable for applications requiring equal or higher performance margins. Physical dimensions are comparable within axial package standards.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF14BAE100R and CMF55100R00BEEB meet ROHS3 compliance and REACH requirements, qualifying them for regulated applications. The substitute part CMF55100R00BEEB provides enhanced performance specifications with higher power dissipation capability (0.5W vs 0.25W) and extended operating temperature range (175°C maximum vs 155°C maximum). The CMF55100R00BEEB additionally features moisture-resistant construction. Selection between these parts depends on circuit power dissipation requirements and thermal operating conditions. Both parts maintain identical electrical characteristics (100 Ohms, ±0.1% tolerance, ±25ppm/°C temperature coefficient) and axial package compatibility.

Frequently Asked Questions (FAQ)

Q: Can CMF55100R00BEEB replace RNF14BAE100R in all applications?

A: Yes, provided the circuit design accommodates the substitute part's physical dimensions. The CMF55100R00BEEB has comparable axial dimensions (0.090" Dia x 0.240" L vs 0.093" Dia x 0.250" L) and identical electrical specifications. The higher power rating and extended temperature range of the substitute part do not create compatibility issues in circuits designed for the main part.

Q: What are the key substitution criteria for this resistor?

A: Substitution is valid when the following parameters match: resistance value (100 Ohms), tolerance (±0.1%), composition (metal film), package type (axial), and temperature coefficient (±25ppm/°C). Compliance certifications (RoHS3, REACH) must also align.

Q: Does the higher power rating of CMF55100R00BEEB affect circuit performance?

A: No. A higher power rating indicates greater thermal dissipation capability and does not negatively impact circuit operation. The substitute part will operate safely in circuits designed for the 0.25W main part.

Q: Are there packaging differences between these parts?

A: The main part is supplied in Tape & Box (TB) packaging, while the substitute is supplied in Cut Tape (CT) packaging. Both are axial through-hole components suitable for standard PCB assembly processes.

Q: What is the temperature coefficient significance for these parts?

A: Both parts share an identical temperature coefficient of ±25ppm/°C, meaning resistance value changes by a maximum of 25 parts per million for each degree Celsius change in operating temperature. This specification is critical for precision applications and is maintained across both the main and substitute parts.
