Parameter Comparison

Engineering Selection Recommendations

CMF55100R00DHR6 (Upgrade Substitute): This part provides improved tolerance (±0.5% vs. ±1%) and superior temperature coefficient (±50ppm/°C vs. ±100ppm/°C), resulting in enhanced precision and stability across the operating temperature range. Electrical and mechanical specifications remain fully compatible. Available in Cut Tape packaging format with higher inventory (1519 units). Compliance status matches the main part. Select this substitute when tighter tolerance and temperature stability are required within the same compliance framework.

CMF55100R00FKEK (Parametric Equivalent): This part maintains identical electrical specifications (±1% tolerance, ±100ppm/°C temperature coefficient) and mechanical compatibility with the main part. Primary distinction is compliance status: ROHS3 compliant and REACH unaffected, compared to the main part's non-compliance. Available in Bulk packaging with highest inventory (1667 units). Select this substitute when RoHS3 compliance or REACH unaffected status is required for regional or customer specifications.

Frequently Asked Questions (FAQ)

Q: Can CMF55100R00DHR6 be used as a direct replacement for CMF55100R00FKBF70?

A: Yes. Both parts share identical resistance (100 Ohms), power rating (0.5W), operating temperature range (-55°C to 175°C), package type (Axial), and physical dimensions (0.090" Dia x 0.240" L). The CMF55100R00DHR6 offers improved tolerance and temperature coefficient specifications, making it a compatible upgrade. Packaging format differs (Cut Tape vs. Bulk) but does not affect electrical or mechanical performance.

Q: What is the difference between CMF55100R00FKEK and the main part?

A: Electrical and mechanical specifications are identical. The primary differences are compliance certifications: CMF55100R00FKEK is ROHS3 compliant and REACH unaffected, while CMF55100R00FKBF70 is non-compliant in both categories. Both are available in Bulk packaging. Select CMF55100R00FKEK when compliance requirements mandate RoHS3 or REACH unaffected status.

Q: Are all three parts interchangeable in circuit design?

A: Yes, for applications where the main part's ±1% tolerance and ±100ppm/°C temperature coefficient are acceptable. CMF55100R00DHR6 provides superior specifications and is also interchangeable. CMF55100R00FKEK is electrically and mechanically identical to the main part. Verify compliance requirements before final selection.

Q: Does packaging format (Bulk vs. Cut Tape) affect compatibility?

A: No. Packaging format affects procurement and handling only. Electrical and mechanical performance are identical regardless of packaging format. Select based on assembly process requirements and inventory needs.

Q: Which substitute should be selected for highest precision applications?

A: CMF55100R00DHR6 provides the tightest tolerance (±0.5%) and lowest temperature coefficient (±50ppm/°C), delivering superior precision and stability across the -55°C to 175°C operating range.
