Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF12FTC3K01 is determined by strict equivalence across the following critical parameters:

• Resistance value: 3.01 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)
• Temperature coefficient: ±50ppm/°C (exact match required)
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected (minimum requirement)

The CMF553K0100FHEB from Vishay Dale meets all substitution criteria. Both parts share identical electrical specifications and axial package configuration, enabling direct functional replacement in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF12FTC3K01 and CMF553K0100FHEB are active production parts with full ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement.

The CMF553K0100FHEB offers an extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 155°C) and includes moisture resistant construction in addition to flame retardant coating. The CMF553K0100FHEB also features a more compact physical profile (0.090" diameter x 0.240" length) compared to the RNF12FTC3K01 (0.108" diameter x 0.344" length), which may provide advantages in space-constrained PCB layouts.

Selection between these parts should be based on application-specific requirements regarding operating temperature limits, available board space, and packaging format preference (Tape & Reel versus Cut Tape).

Frequently Asked Questions (FAQ)

Q: Can the CMF553K0100FHEB directly replace the RNF12FTC3K01 in existing designs?

A: Yes. Both parts share identical electrical specifications (3.01 kOhms ±1%, 0.5W, ±50ppm/°C) and axial package configuration. The CMF553K0100FHEB is physically smaller, which may require PCB layout verification for through-hole spacing and lead clearance.

Q: What is the difference in physical size between these parts?

A: The RNF12FTC3K01 measures 0.108" diameter x 0.344" length. The CMF553K0100FHEB measures 0.090" diameter x 0.240" length. The substitute part is more compact in both dimensions.

Q: Are there temperature range differences?

A: The RNF12FTC3K01 operates from -55°C to 155°C. The CMF553K0100FHEB operates from -55°C to 175°C. The substitute part supports a 20°C higher maximum temperature.

Q: What packaging formats are available?

A: The RNF12FTC3K01 is supplied in Tape & Reel (TR) format. The CMF553K0100FHEB is supplied in Cut Tape (CT) format. Packaging selection depends on assembly process requirements and order quantities.

Q: Do both parts meet current compliance standards?

A: Yes. Both the RNF12FTC3K01 and CMF553K0100FHEB are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.
