Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF12FTC2K67 are qualified based on the following critical parameters:

• Resistance value: 2.67 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 CMF552K6700FHEB from Vishay Dale meets all electrical and mechanical substitution criteria. Both parts share identical resistance, tolerance, power rating, composition, and temperature coefficient specifications. The operating temperature range of the substitute extends to 175°C compared to 155°C for the primary part, providing enhanced thermal performance. Both parts maintain ROHS3 compliance and REACH unaffected status.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF12FTC2K67 and CMF552K6700FHEB are active production parts with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

• Availability: CMF552K6700FHEB has higher inventory (3747 units) compared to RNF12FTC2K67 (704 units)
• Thermal performance: CMF552K6700FHEB supports extended operating temperature to 175°C versus 155°C
• Packaging format: RNF12FTC2K67 is supplied in Tape & Reel format; CMF552K6700FHEB is supplied in Cut Tape format
• Physical dimensions: CMF552K6700FHEB has smaller axial dimensions (0.090" Dia x 0.240" L) compared to RNF12FTC2K67 (0.108" Dia x 0.344" L)

Both parts satisfy identical electrical specifications and regulatory requirements for direct substitution in applications requiring 2.67 kOhms ±1% metal film resistors with 0.5W power rating.

Frequently Asked Questions (FAQ)

Q: Can CMF552K6700FHEB directly replace RNF12FTC2K67 in existing designs?

A: Yes. Both parts have identical resistance value (2.67 kOhms), tolerance (±1%), power rating (0.5W), composition (metal film), and temperature coefficient (±50ppm/°C). The substitute part meets or exceeds all electrical specifications. Physical dimensions differ; verify PCB layout compatibility before implementation.

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

A: RNF12FTC2K67 measures 0.108" Dia x 0.344" L (2.75mm x 8.75mm). CMF552K6700FHEB measures 0.090" Dia x 0.240" L (2.29mm x 6.10mm). The substitute is smaller in both diameter and length, which may affect board layout and component spacing.

Q: Are there differences in operating temperature ranges?

A: RNF12FTC2K67 operates from -55°C to 155°C. CMF552K6700FHEB operates from -55°C to 175°C. The substitute provides extended high-temperature capability. Both parts maintain ±50ppm/°C temperature coefficient across their respective ranges.

Q: What packaging formats are available?

A: RNF12FTC2K67 is supplied in Tape & Reel (TR) format. CMF552K6700FHEB is supplied in Cut Tape (CT) format. Select based on assembly process requirements and volume needs.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both RNF12FTC2K67 and CMF552K6700FHEB are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.
