RT0402FRE0726K7L Equivalent & Substitute Parts

Part Overview

The RT0402FRE0726K7L is a 26.7 kOhms ±1% thin film chip resistor in 0402 (1005 Metric) package manufactured by YAGEO. This surface-mount device is rated for 0.063W (1/16W) power dissipation and operates across -55°C to 155°C. The part is Active status and ROHS3 compliant, making it suitable for standard commercial and industrial applications requiring precision resistive elements in compact form factors.

Equivalent and substitute parts are identified when design requirements allow for improved tolerance specifications, enhanced temperature stability, or automotive-grade certifications while maintaining electrical and mechanical compatibility.

CPF0402B26K7E1 (TE Connectivity Neohm series): Equivalent precision-grade substitute with ±0.1% tolerance and ±25ppm/°C temperature coefficient. Maintains all mechanical and electrical compatibility parameters.

ERA-2AEB2672X (Panasonic ERA-2A series): Automotive-grade substitute with AEC-Q200 certification. Offers ±0.1% tolerance and ±25ppm/°C temperature coefficient. Maximum seated height is 0.40mm versus 0.35mm for other options; verify PCB clearance in space-constrained layouts.

All substitutes maintain ROHS3 compliance, MSL Level 1 rating, and full operating temperature range coverage.

Frequently Asked Questions (FAQ)

Q: Can RT0402BRD0726K7L replace RT0402FRE0726K7L directly? A: Yes. Both parts share identical 0402 package dimensions, resistance value, power rating, and operating temperature range. The substitute offers improved tolerance (±0.1% vs ±1%) and better temperature coefficient (±25ppm/°C vs ±50ppm/°C).

Q: What is the difference between RT0402BRD0726K7L and RT0402BRE0726K7L? A: Both offer ±0.1% tolerance and identical package specifications. RT0402BRD0726K7L has ±25ppm/°C temperature coefficient, while RT0402BRE0726K7L has ±50ppm/°C. Selection depends on temperature stability requirements.

Q: Is ERA-2AEB2672X suitable for non-automotive applications? A: Yes. AEC-Q200 certification indicates automotive-grade reliability but does not restrict use in commercial or industrial applications. The part meets all standard compliance requirements (ROHS3, REACH).

Q: Does the 0.40mm height of ERA-2AEB2672X affect PCB compatibility? A: The 0.05mm height difference (0.40mm vs 0.35mm) is within typical PCB assembly tolerances. Verify clearance in applications with height-critical constraints or high-density layouts.

Q: Are all substitutes available in Tape & Reel packaging? A: Yes. All listed substitutes are supplied in Tape & Reel (TR) format, maintaining supply chain compatibility with standard pick-and-place assembly processes.

Q: Can I use these substitutes interchangeably in production? A: Yes, provided your design specifications allow for the improved tolerance and temperature coefficient characteristics. No circuit redesign is required for electrical or mechanical compatibility.
