Substitute Part Grouping Explanation

The CMF55100R00DHR6 qualifies as a substitute for the CMF55100R00FNRE based on the following allowed parameter alignment:

• Identical resistance value: 100 Ohms
• Identical power rating: 0.5W (1/2W)
• Identical composition: Metal Film
• Identical package type: Axial
• Identical operating temperature range: -55°C to 175°C
• Identical physical dimensions: 0.090" Dia x 0.240" L (2.29mm x 6.10mm)
• Identical features: Flame Retardant Coating, Moisture Resistant, Safety
• Identical series: CMF
• Identical product status: Active

The substitute part differs in tolerance specification (±0.5% versus ±1%) and temperature coefficient (±50ppm/°C versus ±200ppm/°C), representing improved precision characteristics. Packaging format differs (Cut Tape versus Tape & Reel), which affects procurement and assembly logistics but not electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the CMF55100R00FNRE and CMF55100R00DHR6 maintain active product status from Vishay Dale and share identical compliance classifications (RoHS non-compliant, REACH Affected). The substitute part CMF55100R00DHR6 provides tighter tolerance (±0.5% versus ±1%) and lower temperature coefficient (±50ppm/°C versus ±200ppm/°C), making it suitable for applications requiring higher precision. The primary distinction is packaging format: the main part is supplied in Tape & Reel format while the substitute is supplied in Cut Tape format. Selection between these parts should be based on procurement requirements, assembly equipment compatibility, and precision specifications of the target application.

Frequently Asked Questions (FAQ)

Q: Can CMF55100R00DHR6 be used as a direct replacement for CMF55100R00FNRE?

A: Yes. Both parts share identical electrical specifications (100 Ohms, 0.5W, Metal Film), identical physical dimensions (0.090" Dia x 0.240" L), identical operating temperature range (-55°C to 175°C), and identical protective features (Flame Retardant Coating, Moisture Resistant, Safety). The substitute offers improved tolerance and temperature coefficient characteristics.

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 equipment. Cut Tape (CT) packaging supplies components on tape segments cut to specific lengths, typically for manual assembly or lower-volume applications. Both formats contain identical components; the difference is in procurement and assembly logistics.

Q: Does the tighter tolerance of CMF55100R00DHR6 affect compatibility?

A: No. The CMF55100R00DHR6 tolerance of ±0.5% is a subset of the CMF55100R00FNRE tolerance of ±1%, meaning the substitute part meets or exceeds the original specification. This represents an improvement in precision, not a compatibility issue.

Q: Are there compliance differences between these parts?

A: No. Both parts share identical RoHS and REACH compliance status (RoHS non-compliant, REACH Affected). Compliance classifications are identical.

Q: What is the temperature coefficient difference?

A: The CMF55100R00FNRE has a temperature coefficient of ±200ppm/°C, while the CMF55100R00DHR6 has ±50ppm/°C. Lower temperature coefficient indicates better resistance stability across temperature variations. Both operate across the identical temperature range of -55°C to 175°C.
