RT0603FRE072K26L Equivalent & Substitute Parts

Part Overview

The RT0603FRE072K26L is a 2.26 kOhms ±1% thin film chip resistor in 0603 (1608 Metric) package manufactured by YAGEO. This surface-mount device is rated for 0.1W (1/10W) power dissipation with a temperature coefficient of ±50ppm/°C and operates across -55°C to 155°C. The part is ROHS3 compliant with MSL 1 rating and is currently in active production status with 707 units in stock.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when design requirements demand improved tolerance specifications, when automotive-grade certification is required, or when alternative manufacturer sourcing is needed for supply chain resilience.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following mandatory parameters:

Resistance Value: Must be 2.26 kOhms
Package Type: Must be 0603 (1608 Metric)
Composition: Must be Thin Film
Operating Temperature Range: Must support -55°C to 155°C minimum
RoHS Compliance: Must be ROHS3 compliant
MSL Rating: Must be MSL 1 or equivalent

Tolerance, power rating, and temperature coefficient may vary within acceptable ranges for direct substitution. Parts with improved tolerance (±0.1% or ±0.5%) are classified as upgrades. Parts with higher power ratings (1/6W) or automotive certification (AEC-Q200) are classified as direct substitutes with enhanced capabilities. All substitute parts maintain identical footprint and mechanical compatibility.

Engineering Selection Recommendations

Direct Equivalents (Same Tolerance ±1%)

MCT06030C2261FP500 from Vishay Beyschlag is a direct equivalent with identical electrical specifications. This part features anti-sulfur coating for enhanced reliability in corrosive environments and maintains the same ±1% tolerance and ±50ppm/°C temperature coefficient as the primary part.

Upgrade Options (Improved Tolerance ±0.1%)

RT0603BRD072K26L, ERA-3AEB2261V, RG1608P-2261-B-T5, and RP73PF1J2K26BTDF all offer ±0.1% tolerance with ±25ppm/°C temperature coefficient. These parts provide superior accuracy for precision applications. ERA-3AEB2261V includes automotive AEC-Q200 certification for applications requiring automotive-grade reliability. RG1608P-2261-B-T5 combines AEC-Q200 certification with anti-sulfur coating.

Mid-Range Tolerance Option (±0.5%)

RT0603DRE072K26L provides ±0.5% tolerance while maintaining the original ±50ppm/°C temperature coefficient, offering a balance between cost and accuracy improvement.

Higher Power Rating Option

RP73PF1J2K26BTDF from TE Connectivity provides 0.167W (1/6W) power rating compared to the standard 0.1W, enabling use in higher power dissipation circuits while maintaining all other electrical specifications.

All substitute parts are ROHS3 compliant with MSL 1 rating and support the full -55°C to 155°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with ±0.1% tolerance in place of the ±1% original?

A: Yes. Parts with tighter tolerance specifications are directly compatible and provide improved accuracy. The ±0.1% tolerance is a superior specification that maintains backward compatibility with circuits designed for ±1% tolerance.

Q: What is the difference between the YAGEO RT series variants?

A: The RT0603FRE072K26L (±1%), RT0603BRD072K26L (±0.1%), and RT0603DRE072K26L (±0.5%) differ in tolerance and temperature coefficient. The FRE variant uses ±50ppm/°C while BRD and DRE variants use ±25ppm/°C (BRD) or ±50ppm/°C (DRE). All maintain identical package and power rating.

Q: Are automotive-grade parts (AEC-Q200) suitable for non-automotive applications?

A: Yes. Automotive-grade parts meet or exceed standard industrial specifications and are fully compatible with non-automotive designs. They provide additional reliability margin without any compatibility concerns.

Q: What does anti-sulfur coating provide?

A: Anti-sulfur coating protects the resistor element from sulfur-containing atmospheric contaminants that can degrade performance over time. This is beneficial in industrial and harsh environments but not required for standard applications.

Q: Can I substitute the RP73PF1J2K26BTDF (1/6W) for the original 1/10W part?

A: Yes. The higher power rating is fully compatible and provides additional thermal margin. The part will operate safely in circuits designed for 0.1W dissipation.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All listed substitutes are supplied in Tape & Reel (TR) packaging with 0603 (1608 Metric) footprint, ensuring compatibility with standard pick-and-place assembly equipment.

Q: Which substitute offers the best overall performance?

A: Selection depends on application requirements. For precision circuits, RT0603BRD072K26L or RG1608P-2261-B-T5 offer ±0.1% tolerance. For automotive applications, ERA-3AEB2261V or RG1608P-2261-B-T5 provide AEC-Q200 certification. For harsh environments, RG1608P-2261-B-T5 combines both AEC-Q200 and anti-sulfur protection.
