RT0805FRE0754K9L Equivalent & Substitute Parts

Part Overview

The RT0805FRE0754K9L is a 54.9 kOhms ±1% thin film chip resistor in 0805 (2012 Metric) package rated at 0.125W (1/8W) power dissipation. Manufactured by YAGEO under the RT series, this component is actively produced and ROHS3 compliant. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements necessitate enhanced specifications such as improved tolerance or automotive qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Mandatory Compatibility Parameters:

• Resistance value: 54.9 kOhms (exact match required)
• Package type: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Operating temperature range: -55°C to 155°C (minimum requirement)
• RoHS compliance: ROHS3 Compliant (minimum requirement)

Allowable Variations:

• Tolerance: May be equal to or better (lower) than ±1%
• Power rating: May be equal to or greater than 0.125W
• Temperature coefficient: May be equal to or better (lower) than ±50ppm/°C
• Height: Seated height up to 0.026" (0.65mm) acceptable within 0805 package constraints

Identified Substitutes:

1. 7-2176093-0 (TE Connectivity Passive Product): Direct substitute with improved tolerance (±0.1%) and higher power rating (0.25W). Temperature coefficient improved to ±25ppm/°C.

2. ERA-6AEB5492V (Panasonic Electronic Components): Upgrade substitute with improved tolerance (±0.1%), automotive AEC-Q200 qualification, and temperature coefficient of ±25ppm/°C. Maintains original power rating of 0.125W.

Parameter Comparison

Engineering Selection Recommendations

RT0805FRE0754K9L (Primary): Select for standard industrial applications where ±1% tolerance and ±50ppm/°C temperature coefficient meet circuit requirements. ROHS3 compliance and unlimited moisture sensitivity support general-purpose deployment.

7-2176093-0 (TE Connectivity): Select when improved tolerance (±0.1%) and lower temperature coefficient (±25ppm/°C) are required for precision analog circuits. Higher power rating (0.25W) provides thermal margin in current-limited applications. Seated height of 0.026" remains within 0805 package specifications.

ERA-6AEB5492V (Panasonic): Select for automotive applications requiring AEC-Q200 qualification. Improved tolerance (±0.1%) and temperature coefficient (±25ppm/°C) support precision requirements while maintaining original power rating and form factor. Active product status ensures long-term availability.

Frequently Asked Questions (FAQ)

Q: Can 7-2176093-0 be used as a direct replacement for RT0805FRE0754K9L?

A: Yes. Both components share identical resistance value (54.9 kOhms), package (0805), composition (thin film), and operating temperature range (-55°C to 155°C). The substitute offers improved tolerance (±0.1% vs ±1%) and temperature coefficient (±25ppm/°C vs ±50ppm/°C). The increased power rating (0.25W vs 0.125W) and slightly greater seated height (0.026" vs 0.024") do not prevent substitution in standard PCB layouts.

Q: Is ERA-6AEB5492V suitable for non-automotive applications?

A: Yes. AEC-Q200 qualification is an additional specification that does not restrict use in non-automotive circuits. The component meets all baseline requirements for the 54.9 kOhms 0805 thin film resistor category and offers improved tolerance and temperature coefficient.

Q: What is the significance of the seated height difference between parts?

A: The RT0805FRE0754K9L has a maximum seated height of 0.024" (0.60mm), while 7-2176093-0 measures 0.026" (0.65mm). Both values fall within 0805 package specifications. Height difference is relevant only in space-constrained applications with minimal clearance above the PCB surface.

Q: Are all three parts ROHS3 compliant?

A: Yes. RT0805FRE0754K9L, 7-2176093-0, and ERA-6AEB5492V are all ROHS3 compliant with moisture sensitivity level 1 (unlimited), supporting deployment in regulated environments.

Q: Which substitute offers the best performance?

A: Selection depends on application requirements. 7-2176093-0 provides the highest power rating (0.25W). ERA-6AEB5492V provides automotive qualification (AEC-Q200). Both substitutes offer identical tolerance (±0.1%) and temperature coefficient (±25ppm/°C) improvements over the primary part.
