RT0805FRE07442RL Equivalent & Substitute Parts

Part Overview

The RT0805FRE07442RL is a 442 Ohms ±1% thin film chip resistor in 0805 (2012 Metric) package manufactured by YAGEO. This surface mount device is rated for 0.125W (1/8W) power dissipation with an operating temperature range of -55°C to 155°C. The part is currently active in production and ROHS3 compliant, making it suitable for standard industrial and commercial applications requiring precision resistive elements.

Equivalent and substitute parts are identified when they maintain the same resistance value, package footprint, and operating temperature range while meeting or exceeding the original specifications for tolerance, power rating, and environmental compliance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE07442RL is determined by the following critical parameters:

• Resistance Value: Must be 442 Ohms
• Package Footprint: Must be 0805 (2012 Metric) to ensure PCB compatibility
• Operating Temperature Range: Must support -55°C to 155°C minimum
• Composition: Thin film construction
• Tolerance: ±1% or better (tighter tolerance is acceptable)
• Power Rating: 0.125W or higher (higher power rating is acceptable)
• Compliance: ROHS3 and REACH compliance required

Two substitute parts meet these criteria:

1. 8-2176091-4 (TE Connectivity Passive Product): Direct substitute with improved tolerance (±0.1%) and higher power rating (0.25W)
2. ERA-6AEB4420V (Panasonic Electronic Components): Upgrade substitute with improved tolerance (±0.1%), automotive AEC-Q200 qualification, and equivalent power rating (0.125W)

Parameter Comparison

Engineering Selection Recommendations

RT0805FRE07442RL (Original): Select this part for standard applications where the ±1% tolerance and ±50ppm/°C temperature coefficient meet circuit requirements. ROHS3 compliance and unlimited moisture sensitivity rating support general industrial use.

8-2176091-4 (TE Connectivity): This substitute offers improved tolerance (±0.1%) and higher power dissipation capability (0.25W). The lower temperature coefficient (±25ppm/°C) provides better stability across the operating range. Maximum seated height of 0.026" (0.65mm) is marginally higher than the original; verify clearance in space-constrained layouts. Select this part when enhanced precision and thermal headroom are required.

ERA-6AEB4420V (Panasonic): This substitute provides improved tolerance (±0.1%) with automotive AEC-Q200 qualification. The lower temperature coefficient (±25ppm/°C) and equivalent power rating (0.125W) maintain the original form factor while adding automotive-grade reliability. Maximum seated height matches the original at 0.024" (0.60mm). Select this part for applications requiring automotive-grade components or when enhanced precision is needed without increased power dissipation requirements.

All three parts maintain identical footprint compatibility, operating temperature range, and regulatory compliance status.

Frequently Asked Questions (FAQ)

Q: Can 8-2176091-4 replace RT0805FRE07442RL in any circuit?

A: Yes, 8-2176091-4 is electrically compatible as a direct substitute. The improved tolerance (±0.1% vs ±1%) and higher power rating (0.25W vs 0.125W) make it suitable for the same applications. The maximum seated height difference of 0.002" (0.05mm) is negligible for most PCB designs; verify clearance only in space-constrained applications.

Q: What is the advantage of ERA-6AEB4420V over the original RT0805FRE07442RL?

A: ERA-6AEB4420V provides improved tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C), resulting in better frequency stability and precision. The automotive AEC-Q200 qualification adds reliability assurance for demanding environments. Physical dimensions and power rating remain equivalent to the original.

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

A: Yes, all three parts are supplied in Tape & Reel (TR) packaging in 0805 (2012 Metric) format. Moisture Sensitivity Level is 1 (Unlimited) for all parts, indicating no special storage or handling requirements.

Q: Which substitute should be selected for cost optimization?

A: Cost comparison is not provided in the technical specifications. Consult supplier pricing and inventory availability. Both substitutes offer performance improvements over the original specification.

Q: Do the substitute parts maintain ROHS3 and REACH compliance?

A: Yes, both 8-2176091-4 and ERA-6AEB4420V are ROHS3 compliant and REACH unaffected, matching the original part's regulatory status.
