Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF14FTC169K is determined by the following critical parameters:

• Resistance Value: Must be 169 kOhms
• Tolerance: Must be ±1%
• Composition: Must be Metal Film
• Package Type: Must be Axial
• Temperature Coefficient: Must be ±50ppm/°C
• Compliance: Must maintain ROHS3 and REACH compliance status

The CMF55169K00FHEB qualifies as a substitute based on matching all core electrical parameters. The higher power rating (0.5W vs 0.25W) and extended operating temperature range (-55°C ~ 175°C vs -55°C ~ 155°C) represent performance enhancements that maintain backward compatibility in applications designed for the RNF14FTC169K.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF14FTC169K and CMF55169K00FHEB maintain Active product status and full regulatory compliance under ROHS3 and REACH standards. Selection between these components should be based on application-specific requirements:

The RNF14FTC169K is appropriate for standard applications where the 0.25W power rating and -55°C ~ 155°C operating range satisfy design specifications.

The CMF55169K00FHEB provides enhanced performance margins with doubled power dissipation capability (0.5W) and extended upper temperature limit (175°C), making it suitable for applications requiring higher thermal headroom or operation in elevated temperature environments. The addition of moisture-resistant features provides supplementary environmental protection.

Both components are suitable for direct substitution in circuit designs where the specified electrical parameters are required.

Frequently Asked Questions (FAQ)

Q: Can CMF55169K00FHEB replace RNF14FTC169K in existing designs?

A: Yes. Both components share identical resistance value (169 kOhms), tolerance (±1%), composition (metal film), package type (axial), and temperature coefficient (±50ppm/°C). The substitute part's higher power rating and extended temperature range do not create compatibility issues in applications designed for the original part.

Q: What is the difference in physical dimensions between these parts?

A: RNF14FTC169K measures 0.093" diameter × 0.250" length (2.35mm × 6.35mm). CMF55169K00FHEB measures 0.090" diameter × 0.240" length (2.29mm × 6.10mm). Both are axial package configuration with 2 terminations. Dimensional differences are minor and do not affect standard PCB footprint compatibility for axial resistor layouts.

Q: Are there compliance or certification differences?

A: Both parts maintain ROHS3 compliance and REACH Unaffected status. No compliance disadvantages exist when substituting CMF55169K00FHEB for RNF14FTC169K.

Q: What packaging formats are available?

A: RNF14FTC169K is supplied in Tape & Reel (TR) format. CMF55169K00FHEB is supplied in Cut Tape (CT) format. Packaging format selection depends on assembly process requirements and order quantity considerations.

Q: When should the higher power rating of CMF55169K00FHEB be considered?

A: The 0.5W rating of CMF55169K00FHEB provides additional thermal margin compared to the 0.25W rating of RNF14FTC169K. Applications with higher current flow or elevated ambient temperatures benefit from this enhanced power dissipation capability.
