Substitute Part Grouping Explanation

Substitution eligibility for the RNF14FTC604R is determined by the following criteria:

• Resistance value: 604 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: Axial through-hole (exact match required)
• Temperature coefficient: ±50ppm/°C (exact match required)
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected, EAR99 classification (all required)

The CMF50604R00FHEB from Vishay Dale meets all substitution criteria with identical electrical specifications and regulatory certifications. Physical dimensions differ due to manufacturing tolerances within the axial package category, but both components maintain functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF14FTC604R and CMF50604R00FHEB are Active product status components with full ROHS3 compliance and REACH Unaffected certification. Selection between these parts is based on application requirements and supply chain availability. The CMF50604R00FHEB provides extended operating temperature range to 175°C and includes moisture resistant features, offering enhanced environmental protection in demanding applications. The RNF14FTC604R operates to 155°C and is suitable for standard industrial temperature environments. Both components satisfy identical electrical and regulatory requirements for 604 Ohm ±1% metal film resistor applications.

Frequently Asked Questions (FAQ)

Q: Can CMF50604R00FHEB replace RNF14FTC604R in existing designs?

A: Yes. Both components share identical resistance (604 Ohms), tolerance (±1%), power rating (0.25W), composition (metal film), temperature coefficient (±50ppm/°C), and regulatory compliance (ROHS3, REACH Unaffected). Axial package compatibility is maintained.

Q: What are the physical dimension differences?

A: RNF14FTC604R measures 0.093" diameter × 0.250" length (2.35mm × 6.35mm). CMF50604R00FHEB measures 0.065" diameter × 0.150" length (1.65mm × 3.81mm). Both are axial through-hole packages; dimension differences do not affect electrical performance but may impact PCB layout spacing.

Q: Are there temperature range limitations for substitution?

A: The RNF14FTC604R operates -55°C to 155°C. The CMF50604R00FHEB operates -55°C to 175°C. For applications within the -55°C to 155°C range, both are equivalent. For applications requiring 155°C to 175°C operation, only CMF50604R00FHEB is suitable.

Q: What packaging formats are available?

A: RNF14FTC604R is supplied in Tape & Reel (TR) format. CMF50604R00FHEB is supplied in Cut Tape (CT) format. Packaging format selection depends on assembly process requirements and order quantities.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both components are ROHS3 Compliant, REACH Unaffected, and classified as EAR99 under export control regulations. HTSUS classification is identical (8533.21.0090).
