RT0805FRE07187KL Equivalent & Substitute Parts

Part Overview

The RT0805FRE07187KL is a 187 kOhms ±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 an operating temperature range of -55°C to 155°C. The part is currently active in production and ROHS3 compliant. Substitute parts are identified when equivalent resistance values, package dimensions, and electrical performance parameters align within acceptable tolerances for direct circuit board replacement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RT0805FRE07187KL are qualified based on the following criteria:

Primary Substitution Parameters:

• Resistance value: 187 kOhms (exact match required)
• Package / Case: 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)
• Moisture Sensitivity Level: 1 (Unlimited) (minimum requirement)

Secondary Compatibility Parameters:

• Tolerance: ±1% or better (tighter tolerance acceptable)
• Power Rating: 0.125W or higher (higher power rating acceptable)
• Temperature Coefficient: ±50ppm/°C or better (lower coefficient acceptable)

Three substitute parts meet these criteria with varying performance enhancements.

Parameter Comparison

Engineering Selection Recommendations

RT0805BRD07187KL (YAGEO Upgrade): This substitute offers improved tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C) while maintaining identical power rating, package dimensions, and height. Both parts are YAGEO thin film resistors with ROHS3 compliance and unlimited moisture sensitivity rating. Selection is appropriate for applications requiring tighter resistance tolerance.

2-2176094-0 (TE Connectivity Direct): This substitute provides higher power rating (0.25W versus 0.125W) and improved tolerance (±0.1%) with lower temperature coefficient (±25ppm/°C). The seated height is 0.026" (0.65mm) compared to 0.024" (0.60mm) for the main part. ROHS3 compliance and unlimited moisture sensitivity are maintained. Selection is appropriate for applications with higher power dissipation requirements or where additional thermal margin is beneficial.

ERA-6AEB1873V (Panasonic Upgrade): This substitute is a Panasonic thin film resistor with ±0.1% tolerance, ±25ppm/°C temperature coefficient, and AEC-Q200 automotive qualification. Physical dimensions and height match the main part exactly. ROHS3 compliance and unlimited moisture sensitivity are maintained. Selection is appropriate for automotive applications or where AEC-Q200 qualification is required.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD07187KL be used as a direct replacement for RT0805FRE07187KL?

A: Yes. Both parts are YAGEO 0805 thin film resistors with 187 kOhms resistance, identical package dimensions, and matching operating temperature range. RT0805BRD07187KL offers improved tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C) with no physical incompatibility.

Q: What is the difference between the 0.125W and 0.25W power ratings?

A: Power rating indicates maximum continuous power dissipation. The 2-2176094-0 (0.25W) can dissipate twice the power of the main part (0.125W) before thermal damage occurs. Higher power rating provides additional thermal margin but does not affect electrical performance at equivalent current levels.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant with unlimited moisture sensitivity level (MSL 1), matching the main part's environmental compliance profile.

Q: Why does 2-2176094-0 have a different seated height?

A: The 2-2176094-0 has a maximum seated height of 0.026" (0.65mm) compared to 0.024" (0.60mm) for other parts. This 0.002" (0.05mm) difference is within typical PCB assembly tolerances but should be verified for applications with strict height constraints.

Q: Is ERA-6AEB1873V suitable for non-automotive applications?

A: Yes. ERA-6AEB1873V meets all electrical and environmental requirements for general applications. AEC-Q200 automotive qualification is an additional feature that does not restrict use in non-automotive circuits.

Q: Can tolerance differences affect circuit performance?

A: Tolerance differences affect initial resistance accuracy. The main part (±1%) has wider tolerance than substitutes (±0.1%). Selection depends on circuit requirements for resistance accuracy. Tighter tolerance substitutes are appropriate for precision analog circuits or where resistance matching is critical.
