Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE0737K4L is determined by the following mandatory parameters:

Core Compatibility Requirements:

• Resistance value: 37.4 kOhms (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (minimum requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (minimum requirement)

Allowable Variations:

• Tolerance: May be equal to or tighter than ±1%
• Power Rating: May be equal to or greater than 0.125W
• Temperature Coefficient: May be equal to or tighter than ±50ppm/°C
• RoHS Status: ROHS3 Compliant or equivalent
• Certifications: May include additional automotive or industrial ratings

All identified substitute parts meet these criteria and are electrically and mechanically interchangeable with the main part.

Parameter Comparison

Engineering Selection Recommendations

RT0805BRD0737K4L (YAGEO Upgrade): This substitute offers improved tolerance (±0.1% versus ±1%) and tighter temperature coefficient (±25ppm/°C versus ±50ppm/°C) while maintaining identical power rating, package, and ROHS3 compliance. Selection is appropriate for applications requiring enhanced precision without increased power dissipation requirements.

5-2176093-6 (TE Connectivity Direct): This substitute provides increased power rating (0.25W versus 0.125W) with improved tolerance and temperature coefficient. Height dimension increases marginally (0.026" versus 0.024"). RoHS non-compliance status requires verification against project requirements. Selection is appropriate for applications with higher power dissipation margins or legacy system compatibility needs.

ERA-6AEB3742V (Panasonic Upgrade): This substitute combines improved tolerance (±0.1%), tighter temperature coefficient (±25ppm/°C), and AEC-Q200 automotive certification while maintaining identical power rating and package dimensions. ROHS3 compliance is maintained. Selection is appropriate for automotive applications or systems requiring automotive-grade component qualification.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD0737K4L replace RT0805FRE0737K4L in any application?

A: Yes. RT0805BRD0737K4L is electrically and mechanically compatible. It provides tighter tolerance and temperature coefficient specifications, making it suitable for all applications where RT0805FRE0737K4L is specified. No circuit redesign is required.

Q: What is the primary difference between 5-2176093-6 and the other substitutes?

A: 5-2176093-6 offers doubled power rating (0.25W versus 0.125W) and is manufactured by TE Connectivity rather than YAGEO or Panasonic. It is RoHS non-compliant, which may restrict use in certain regulated applications. Height dimension is marginally increased (0.026" versus 0.024").

Q: Is ERA-6AEB3742V suitable for automotive applications?

A: Yes. ERA-6AEB3742V carries AEC-Q200 automotive certification, making it qualified for automotive-grade applications. It maintains ROHS3 compliance and offers improved tolerance and temperature coefficient specifications compared to the main part.

Q: Are all substitutes available in the same packaging format?

A: Yes. All substitute parts are supplied in Tape & Reel (TR) packaging, matching the main part packaging specification.

Q: Can I use a substitute with higher power rating in a circuit designed for 0.125W?

A: Yes. A component with higher power rating (such as 5-2176093-6 at 0.25W) can be used in applications designed for lower power ratings. The component will operate within safe thermal limits. Physical height variation (0.026" versus 0.024") must be verified against PCB layout constraints.

Q: What tolerance should I specify if the original design calls for ±1%?

A: The original ±1% tolerance can be maintained by selecting RT0805FRE0737K4L. Tighter tolerances (±0.1%) offered by substitute parts are backward-compatible and provide improved circuit performance without requiring design changes.
