Key Parameters

Substitute Part Grouping Explanation

The CMF5526K700FHEB from Vishay Dale qualifies as a direct substitute based on the following critical parameters:

• Identical resistance value: 26.7 kOhms
• Matching tolerance: ±1%
• Equivalent power rating: 0.5W (1/2W)
• Same composition: Metal Film
• Identical package configuration: Axial through-hole
• Matching temperature coefficient: ±50ppm/°C
• Compatible operating temperature range: -55°C ~ 175°C (exceeds minimum requirement)
• Equivalent safety features: Flame Retardant Coating, Safety construction
• Identical regulatory compliance: ROHS3 Compliant, REACH Unaffected

The substitute part maintains all critical electrical and mechanical specifications required for direct replacement. The enhanced operating temperature upper limit (175°C vs. 155°C) and additional moisture resistance feature provide extended capability without compromising compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF12FTC26K7 and CMF5526K700FHEB meet identical electrical and mechanical requirements for 26.7 kOhms ±1% metal film axial resistor applications. Selection between these parts should be based on:

• Availability: CMF5526K700FHEB currently has higher inventory (3091 units vs. 1057 units)
• Packaging requirements: RNF12FTC26K7 supplied in Tape & Reel format; CMF5526K700FHEB supplied in Cut Tape format
• Temperature margin: CMF5526K700FHEB provides extended operating range to 175°C, beneficial for high-temperature applications
• Moisture environment: CMF5526K700FHEB includes moisture-resistant feature for humid or corrosive environments

Both parts maintain full ROHS3 compliance and REACH compliance status. No performance degradation occurs with either selection for applications within the specified electrical and thermal parameters.

Frequently Asked Questions (FAQ)

Q: Can CMF5526K700FHEB directly replace RNF12FTC26K7 in existing designs?

A: Yes. Both components share identical resistance (26.7 kOhms), tolerance (±1%), power rating (0.5W), composition (metal film), temperature coefficient (±50ppm/°C), and axial package configuration. The substitute part meets or exceeds all electrical and mechanical specifications.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, suitable for automated assembly lines. Cut Tape (CT) packaging supplies components on tape segments cut to specific lengths, suitable for manual assembly or smaller production runs. Both formats contain identical components; packaging format selection depends on assembly process requirements.

Q: Does the extended operating temperature range of CMF5526K700FHEB affect compatibility?

A: No. The CMF5526K700FHEB operating range of -55°C ~ 175°C encompasses the RNF12FTC26K7 range of -55°C ~ 155°C. The extended upper temperature limit provides additional design margin without introducing incompatibility.

Q: Are there any regulatory or compliance differences between these parts?

A: No. Both parts are ROHS3 Compliant and REACH Unaffected. Regulatory status is identical, and both parts are suitable for applications requiring these certifications.

Q: What does the moisture-resistant feature on CMF5526K700FHEB provide?

A: Moisture resistance improves component reliability in humid environments, high-altitude applications, or systems with condensation exposure. This feature does not affect electrical performance but extends operational life in moisture-prone conditions.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes. Both components use identical axial package configuration with two terminations. PCB footprints, lead spacing, and mounting requirements are compatible. No design modifications are required for substitution.
