Substitute Part Grouping Explanation

Substitution eligibility for the RNF14FTC162R is determined by strict equivalence across the following parameters:

• Resistance value: 162 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Composition: Metal Film (exact match required)
• Package configuration: Axial through-hole (exact match required)
• Temperature coefficient: ±50ppm/°C (exact match required)
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected (minimum requirement)

The CMF50162R00FHEB from Vishay Dale meets all substitution criteria. Both parts share identical electrical specifications and regulatory certifications. Physical dimensions differ due to manufacturing process variations between suppliers, but both maintain axial package compatibility for standard through-hole PCB applications.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF14FTC162R and CMF50162R00FHEB are Active status components with full ROHS3 compliance and REACH Unaffected designation, meeting current regulatory requirements for electronic component procurement. Selection between these parts is based on application-specific requirements and supply chain availability.

The CMF50162R00FHEB provides an extended operating temperature range to 175°C compared to the RNF14FTC162R's 155°C maximum, offering additional thermal margin for high-temperature applications. The CMF50162R00FHEB also includes moisture-resistant features beyond the flame retardant coating present in both designs.

Physical dimensions differ: the RNF14FTC162R measures 0.093" diameter × 0.250" length (2.35mm × 6.35mm), while the CMF50162R00FHEB measures 0.065" diameter × 0.150" length (1.65mm × 3.81mm). Both configurations are compatible with standard axial through-hole PCB layouts, though the smaller CMF50162R00FHEB may offer space advantages in compact designs.

Frequently Asked Questions (FAQ)

Q: Can the CMF50162R00FHEB directly replace the RNF14FTC162R in existing designs?

A: Yes. Both parts share identical electrical specifications (162 Ohms ±1%, 0.25W, ±50ppm/°C) and regulatory compliance. Both are axial through-hole components compatible with standard PCB footprints. Physical dimension differences do not affect electrical performance or mechanical fit in typical applications.

Q: What is the significance of the extended temperature range in the CMF50162R00FHEB?

A: The CMF50162R00FHEB operates to 175°C versus 155°C for the RNF14FTC162R. This extended range provides additional thermal margin for applications operating near maximum ambient temperatures or experiencing localized heating. Selection depends on specific application thermal requirements.

Q: Are there packaging differences between these parts?

A: The RNF14FTC162R is supplied in Tape & Reel (TR) packaging, while the CMF50162R00FHEB is supplied in Cut Tape (CT) packaging. Both are standard formats for through-hole component distribution. Packaging selection depends on assembly process requirements and volume considerations.

Q: What does the moisture-resistant feature in the CMF50162R00FHEB provide?

A: Moisture-resistant coating enhances performance in humid or corrosive environments by reducing moisture ingress and potential corrosion of component leads and internal elements. This feature is beneficial for applications in marine, outdoor, or high-humidity industrial settings.

Q: Are both parts suitable for high-reliability applications?

A: Both parts carry ROHS3 compliance and REACH Unaffected status, meeting current regulatory standards. Both feature flame retardant coating and safety design. Component selection for high-reliability applications should include evaluation of supplier quality certifications, failure rate data, and application-specific environmental stress screening requirements beyond the parameters provided.
