Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF12FTC215R are identified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

• Resistance value: 215 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: Axial through-hole (exact match required)
• Temperature coefficient: ±50ppm/°C (exact match required)
• Compliance: ROHS3 Compliant, REACH Unaffected (exact match required)

The CMF55215R00FHEB from Vishay Dale meets all electrical specifications and compliance requirements. Physical dimensions differ slightly, but both parts maintain axial package compatibility within standard PCB design tolerances.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF12FTC215R and CMF55215R00FHEB are Active status products with full ROHS3 compliance and REACH Unaffected certification. Selection between these parts depends on application-specific requirements:

The RNF12FTC215R is suitable for standard applications within the -55°C to 155°C operating range with Tape & Reel packaging for automated assembly processes.

The CMF55215R00FHEB offers an extended operating temperature range to 175°C and includes moisture-resistant features, with Cut Tape packaging suitable for manual or selective assembly operations. The CMF55 series exhibits smaller physical dimensions, which may provide advantages in space-constrained PCB layouts.

Both parts satisfy identical electrical specifications and regulatory requirements, making either suitable for direct substitution in applications where the specified parameters are the design criteria.

Frequently Asked Questions (FAQ)

Q: Can CMF55215R00FHEB replace RNF12FTC215R in all applications?

A: Yes, provided the application does not require Tape & Reel packaging format. Both parts meet identical electrical specifications (215 Ohms ±1%, 0.5W, ±50ppm/°C) and compliance standards. The CMF55215R00FHEB operates to 175°C versus 155°C for the RNF12FTC215R, providing additional thermal margin.

Q: What is the impact of different physical dimensions?

A: The CMF55215R00FHEB is physically smaller (0.090" Dia x 0.240" L versus 0.108" Dia x 0.344" L). Both maintain standard axial package geometry compatible with through-hole PCB designs. Verify PCB footprint spacing accommodates the smaller CMF55 dimensions if space is critical.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel (TR) and Cut Tape (CT) packaging formats affect only handling and assembly processes, not electrical characteristics. Selection depends on manufacturing equipment and assembly workflow requirements.

Q: Are moisture-resistant features required for my application?

A: The CMF55215R00FHEB includes moisture-resistant features while the RNF12FTC215R does not. Both are suitable for standard industrial environments. Applications in high-humidity or marine environments may benefit from the moisture-resistant specification of the CMF55 series.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic components in EU and global markets.
