Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF12FTC732R are identified based on strict electrical and mechanical compatibility criteria. The primary substitution logic is based on the following allowed parameters:

• Resistance value: 732 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.5W / 1/2W (exact match required)
• Composition: Metal Film (exact match required)
• Package type: Axial (exact match required)
• Temperature coefficient: ±50ppm/°C (exact match required)
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected (exact match required)

The CMF55732R00FHEB from Vishay Dale meets all electrical specifications and regulatory requirements. Physical dimensions differ slightly, and the operating temperature range extends to 175°C (versus 155°C for the main part), with additional moisture resistance features. These differences do not affect substitution eligibility within the defined parameter set.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF12FTC732R and CMF55732R00FHEB are Active products with full ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronic component procurement. Selection between these parts should be based on:

• Packaging requirements: The RNF12FTC732R is supplied in Tape & Reel format, while the CMF55732R00FHEB is supplied in Cut Tape format. Procurement and assembly processes may dictate preference.
• Physical space constraints: The CMF55732R00FHEB has a smaller physical footprint (0.090" diameter vs. 0.108" diameter, 0.240" length vs. 0.344" length), which may be advantageous in compact circuit designs.
• Extended temperature performance: The CMF55732R00FHEB operates to 175°C versus 155°C for the RNF12FTC732R, providing additional thermal margin in high-temperature applications.
• Moisture resistance: The CMF55732R00FHEB includes moisture-resistant features, beneficial for applications in humid or corrosive environments.

Frequently Asked Questions (FAQ)

Q: Can the CMF55732R00FHEB directly replace the RNF12FTC732R in existing designs?

A: Yes, the CMF55732R00FHEB meets all electrical specifications (732 Ohms ±1%, 0.5W, ±50ppm/°C) and regulatory requirements (ROHS3, REACH Unaffected) required for direct substitution. Physical dimensions differ, but both are axial through-hole components suitable for standard PCB layouts. Verify mechanical clearance in space-constrained applications.

Q: What are the key differences between these two parts?

A: The primary differences are physical dimensions, operating temperature range, packaging format, and moisture resistance features. The CMF55732R00FHEB is smaller, operates to a higher temperature (175°C vs. 155°C), includes moisture resistance, and is supplied in Cut Tape rather than Tape & Reel format.

Q: Are there any compatibility concerns with PCB assembly?

A: Both parts are axial through-hole resistors with 2 terminations and are compatible with standard PCB assembly equipment. The smaller diameter of the CMF55732R00FHEB may require verification of lead hole sizing, though standard 0.040" holes accommodate both components.

Q: Which part should be selected for new designs?

A: Selection depends on specific application requirements. For standard applications, either part is acceptable. For high-temperature environments, moisture-prone locations, or space-constrained designs, the CMF55732R00FHEB offers advantages. For existing supply chain commitments or Tape & Reel packaging requirements, the RNF12FTC732R remains appropriate.

Q: Are both parts available in equivalent quantities?

A: Current inventory shows 1041 pieces of RNF12FTC732R and 2245 pieces of CMF55732R00FHEB available. Packaging formats differ (Tape & Reel vs. Cut Tape), which may affect procurement quantities and lead times.
