RT0805FRE0711R3L Equivalent & Substitute Parts

Part Overview

The RT0805FRE0711R3L is an 11.3 Ohm ±1% thin film chip resistor in 0805 (2012 Metric) package manufactured by YAGEO. This component is rated for 0.125W (1/8W) power dissipation with a temperature coefficient of ±50ppm/°C and operates across -55°C to 155°C. The part maintains Active product status and is ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. Substitute parts are identified when equivalent resistance values, package dimensions, and operating temperature ranges are maintained while allowing variations in tolerance, power rating, and temperature coefficient within acceptable engineering parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE0711R3L is determined by the following critical parameters:

• Resistance Value: Must be 11.3 Ohms (exact match required)
• Package / Case: Must be 0805 (2012 Metric) with matching physical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm)
• Composition: Must be Thin Film construction
• Operating Temperature Range: Must support -55°C to 155°C minimum
• Termination Count: Must have 2 terminations

Tolerance, power rating, and temperature coefficient may vary provided the substitute part meets or exceeds the performance requirements of the application circuit. The identified substitute part 3-1625868-2 satisfies all critical substitution criteria.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 3-1625868-2 from TE Connectivity Passive Product (RP73P series, Holsworthy) is a direct functional equivalent for the RT0805FRE0711R3L. Both parts maintain Active product status and ROHS3 compliance. The substitute offers improved tolerance (±0.1% versus ±1%) and higher power dissipation capability (0.25W versus 0.125W), with a lower temperature coefficient (±25ppm/°C versus ±50ppm/°C). Physical compatibility is confirmed through identical package designation and matching operating temperature range. The maximum seated height difference of 0.002" (0.05mm) remains within standard PCB assembly tolerances for 0805 components.

Frequently Asked Questions (FAQ)

Q: Can the 3-1625868-2 be used as a direct replacement for the RT0805FRE0711R3L?

A: Yes. Both parts share identical 11.3 Ohm resistance, 0805 package dimensions, thin film composition, and -55°C to 155°C operating temperature range. The substitute meets all critical substitution parameters.

Q: What are the advantages of using the TE Connectivity 3-1625868-2 substitute?

A: The substitute provides tighter tolerance (±0.1% versus ±1%), higher power rating (0.25W versus 0.125W), and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C). These characteristics may improve circuit stability and thermal performance in applications requiring higher precision or power dissipation.

Q: Are there any physical compatibility concerns with the substitute part?

A: No. Both parts conform to the 0805 (2012 Metric) package standard with matching length and width dimensions (2.00mm x 1.25mm). The maximum seated height of the substitute is 0.026" (0.65mm) compared to 0.024" (0.60mm) for the original part, a difference of 0.002" (0.05mm) that remains within standard PCB assembly tolerances.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the RT0805FRE0711R3L and 3-1625868-2 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, supporting equivalent environmental and regulatory requirements.

Q: What is the significance of the tolerance difference between these parts?

A: The substitute part's ±0.1% tolerance is tighter than the original ±1% tolerance. In precision analog circuits, this tighter tolerance may reduce circuit calibration drift and improve overall system accuracy. For general-purpose applications, both tolerances are functionally equivalent.
