Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNMF12FTD23K2 is determined by the following critical parameters:

• Resistance value: 23.2 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.5W / 1/2W (exact match required)
• Composition: Metal Film (exact match required)
• Package: Axial through-hole (exact match required)
• RoHS compliance: ROHS3 Compliant (maintained)
• Product status: Active (current production)

The CMF5523K200FHEB from Vishay Dale meets all substitution criteria with identical electrical specifications and compatible mechanical dimensions within axial package tolerances.

Parameter Comparison

Engineering Selection Recommendations

Both the RNMF12FTD23K2 and CMF5523K200FHEB are active production components with ROHS3 compliance and REACH unaffected status. The CMF5523K200FHEB offers an extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 155°C) and improved temperature coefficient stability (±50ppm/°C versus ±100ppm/°C). The CMF5523K200FHEB includes moisture-resistant features in addition to flame retardant coating. Both components are suitable for direct substitution in applications requiring 23.2 kOhms ±1% metal film axial resistors at 0.5W power dissipation. Dimensional differences are within standard axial package tolerances and do not affect PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can the CMF5523K200FHEB replace the RNMF12FTD23K2 in existing designs?

A: Yes. Both components share identical electrical specifications (23.2 kOhms ±1%, 0.5W, metal film composition) and axial package type. Dimensional variations (0.093" vs 0.090" diameter, 0.250" vs 0.240" length) are within standard axial resistor tolerances and do not require PCB redesign.

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

A: The CMF5523K200FHEB provides superior temperature stability (±50ppm/°C versus ±100ppm/°C), extended operating temperature range (175°C versus 155°C maximum), and moisture-resistant coating in addition to flame retardant properties. Both maintain ROHS3 compliance and active production status.

Q: Are there any compliance or certification differences?

A: No. Both components are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Both carry identical HTSUS classification (8533.21.0090).

Q: What packaging formats are available for these parts?

A: The RNMF12FTD23K2 is supplied in Tape & Reel (TR) format. The CMF5523K200FHEB is supplied in Cut Tape (CT) format. Both formats are compatible with standard component handling and assembly processes.

Q: Are these parts suitable for high-temperature applications?

A: The CMF5523K200FHEB supports operation up to 175°C, making it suitable for higher-temperature environments. The RNMF12FTD23K2 is rated to 155°C. Selection depends on specific application temperature requirements.
