Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF12FTC332R is determined by the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 332 Ohms (exact match required)
• Tolerance: ±1% (equivalent or tighter tolerance acceptable)
• Power rating: 0.5W minimum (equal or higher acceptable)
• Composition: Metal Film (maintains performance characteristics)
• Temperature coefficient: ±50ppm/°C or better

Mechanical Compatibility Requirements:

• Package type: Axial through-hole configuration
• Number of terminations: 2 (standard axial leads)
• Physical form factor: Compatible with standard PCB axial component footprints

Regulatory & Compliance Requirements:

• RoHS3 Compliance (mandatory for equivalent substitution)
• REACH Unaffected status
• ECCN classification: EAR99

The CMF55332R00FHEB from Vishay Dale meets all substitution criteria while maintaining functional equivalence and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The CMF55332R00FHEB qualifies as a direct substitute for the RNF12FTC332R based on electrical and mechanical equivalence. Both components are Active products with ROHS3 compliance and EAR99 classification. The Vishay Dale part provides an extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 155°C) and includes moisture-resistant features, offering enhanced environmental performance within the same electrical specification envelope. Selection between these parts should be based on application requirements, supply chain availability, and packaging format preference (Tape & Reel versus Cut Tape).

Frequently Asked Questions (FAQ)

Q: Can the CMF55332R00FHEB replace the RNF12FTC332R in all applications?

A: Yes, the CMF55332R00FHEB meets all electrical and mechanical substitution criteria. Both components share identical resistance (332 Ohms), tolerance (±1%), power rating (0.5W), composition (metal film), and temperature coefficient (±50ppm/°C). Axial package compatibility is maintained. Both are ROHS3 compliant with EAR99 classification.

Q: What are the physical differences between these parts?

A: The RNF12FTC332R measures 0.108" diameter × 0.344" length (2.75mm × 8.75mm). The CMF55332R00FHEB measures 0.090" diameter × 0.240" length (2.29mm × 6.10mm). The Vishay part is physically smaller while maintaining identical electrical performance and axial lead configuration.

Q: Does the extended temperature range of the CMF55332R00FHEB affect substitution suitability?

A: No. The extended operating range (-55°C ~ 175°C versus -55°C ~ 155°C) represents an enhancement that does not compromise substitution eligibility. Applications operating within the original temperature specification remain fully compatible.

Q: Are there packaging format differences to consider?

A: Yes. The RNF12FTC332R is supplied in Tape & Reel (TR) format, while the CMF55332R00FHEB is supplied in Cut Tape (CT) format. Both formats are standard for axial through-hole resistors. Selection should align with assembly process requirements and inventory management practices.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the RNF12FTC332R and CMF55332R00FHEB are ROHS3 compliant, REACH Unaffected, and classified as EAR99. Regulatory compliance is equivalent across both components.
