RT0805CRE07187RL Equivalent & Substitute Parts

Part Overview

The RT0805CRE07187RL is a 187 Ohm thin film chip resistor manufactured by YAGEO in the 0805 (2012 Metric) package format. This surface mount device delivers 0.125W (1/8W) power dissipation with ±0.25% tolerance and operates across the -55°C to 155°C temperature range. The part maintains Active product status with ROHS3 compliance and MSL 1 rating, making it suitable for general industrial and commercial applications requiring precision resistive elements.

Equivalent and substitute parts are identified based on matching resistance value, package format, and electrical performance parameters that permit direct circuit substitution without design modification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Primary Matching Parameters:

• Resistance value: 187 Ohms (exact match required)
• Package format: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Operating temperature range: -55°C ~ 155°C (minimum requirement)

Secondary Compatibility Parameters:

• Power rating: Equal to or greater than 0.125W
• Tolerance: Equal to or tighter than ±0.25%
• Temperature coefficient: Equal to or lower absolute value than ±50ppm/°C
• RoHS and MSL compliance: ROHS3 Compliant, MSL 1

Three substitute parts meet these criteria with varying performance enhancements:

1. RT0805BRD07187RL (YAGEO) – Tighter tolerance upgrade (±0.1%) with improved temperature coefficient (±25ppm/°C), same power rating
2. 5-2176091-0 (TE Connectivity) – Enhanced power rating (0.25W) with tighter tolerance (±0.1%) and improved temperature coefficient (±25ppm/°C)
3. ERA-6AEB1870V (Panasonic) – Tighter tolerance (±0.1%), improved temperature coefficient (±25ppm/°C), automotive AEC-Q200 qualified

Parameter Comparison

Engineering Selection Recommendations

All four parts maintain Active product status and ROHS3 compliance, ensuring long-term availability and regulatory conformance.

RT0805BRD07187RL provides tolerance and temperature coefficient improvements over the primary part while maintaining identical power rating and package specifications. Selection is appropriate for applications requiring enhanced precision without increased thermal dissipation requirements.

5-2176091-0 offers doubled power rating (0.25W versus 0.125W) alongside tolerance and temperature coefficient enhancements. This part accommodates higher current or thermal stress conditions within the same physical footprint. Height specification increases marginally (0.026" versus 0.024"), which may require verification in space-constrained layouts.

ERA-6AEB1870V combines tolerance and temperature coefficient improvements with automotive AEC-Q200 qualification. This part is specified for applications requiring automotive-grade reliability and qualification documentation, with substantially higher inventory availability (20,686 units).

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD07187RL directly replace RT0805CRE07187RL?

A: Yes. Both parts share identical resistance, package format, power rating, and operating temperature range. RT0805BRD07187RL provides tighter tolerance (±0.1% versus ±0.25%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), making it a direct upgrade with no circuit modification required.

Q: What is the primary difference between 5-2176091-0 and the other substitutes?

A: 5-2176091-0 provides 0.25W power rating compared to 0.125W in the other parts. This doubled power capacity accommodates higher current applications. Physical height increases from 0.024" to 0.026", requiring layout verification in height-restricted designs.

Q: Is ERA-6AEB1870V suitable for non-automotive applications?

A: Yes. ERA-6AEB1870V meets all electrical and mechanical requirements for the primary part. AEC-Q200 qualification represents additional testing and documentation; it does not restrict use in non-automotive circuits. The part is functionally equivalent for general industrial and commercial applications.

Q: Do all substitute parts maintain the same package footprint?

A: All parts use the 0805 (2012 Metric) package with identical length (0.079") and width (0.049"). Height specifications are 0.024" for RT0805CRE07187RL, RT0805BRD07187RL, and ERA-6AEB1870V, and 0.026" for 5-2176091-0. Verify clearance in designs with height constraints.

Q: Are tolerance differences significant for circuit operation?

A: Tolerance impact depends on circuit function. Applications with tight resistance specifications benefit from ±0.1% tolerance parts (RT0805BRD07187RL, 5-2176091-0, ERA-6AEB1870V). General-purpose circuits typically accept ±0.25% tolerance. Temperature coefficient differences (±50ppm/°C versus ±25ppm/°C) affect long-term stability across temperature extremes; lower coefficients provide superior performance in temperature-sensitive applications.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, with layout verification for 5-2176091-0 due to increased height. All parts are pin-compatible, electrically equivalent within specified parameters, and maintain identical solder pad patterns for the 0805 package format.
