Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF12FTC75R0 is determined by the following critical parameters:

• Electrical Match: Resistance value of 75 Ohms with ±1% tolerance
• Power Rating: 0.5W (1/2W) minimum
• Composition: Metal film construction
• Package Configuration: Axial through-hole leads with 2 terminations
• Temperature Coefficient: ±50ppm/°C
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected, EAR99 classification
• Safety Features: Flame retardant coating and safety-rated construction

The CMF5575R000FHEB from Vishay Dale meets all substitution criteria within these parameters. Both parts maintain identical electrical specifications and regulatory certifications, with compatible mechanical form factors suitable for direct board-level replacement.

Parameter Comparison

Engineering Selection Recommendations

The CMF5575R000FHEB provides an extended operating temperature range to 175°C and includes moisture-resistant properties, offering enhanced environmental protection. Selection between these parts should be based on application-specific temperature requirements and packaging availability. The CMF5575R000FHEB is currently available in higher inventory (4373 units) compared to the RNF12FTC75R0 (908 units).

Frequently Asked Questions (FAQ)

Q: Can the CMF5575R000FHEB directly replace the RNF12FTC75R0 in existing designs?

A: Yes. Both parts share identical electrical specifications (75 Ohms ±1%, 0.5W, ±50ppm/°C) and axial package configuration with 2 terminations. Both are ROHS3 compliant and safety-rated with flame retardant coating.

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

A: The RNF12FTC75R0 measures 0.108" Dia x 0.344" L (2.75mm x 8.75mm). The CMF5575R000FHEB measures 0.090" Dia x 0.240" L (2.29mm x 6.10mm). The substitute part is physically smaller, which may affect board layout considerations.

Q: Are there temperature range limitations when substituting?

A: The RNF12FTC75R0 operates from -55°C to 155°C, while the CMF5575R000FHEB extends to 175°C. For applications within the -55°C to 155°C range, both parts are functionally equivalent. Applications requiring operation above 155°C must use the RNF12FTC75R0 or verify the CMF5575R000FHEB's suitability.

Q: What packaging formats are available for each part?

A: The RNF12FTC75R0 is supplied in Tape & Reel (TR) format. The CMF5575R000FHEB is supplied in Cut Tape (CT) format. Packaging selection should align with assembly process requirements and volume needs.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the RNF12FTC75R0 and CMF5575R000FHEB are ROHS3 compliant, REACH unaffected, and classified as EAR99 under export control regulations.
