CRL0805-FW-R200ELF Equivalent & Substitute Parts

Part Overview

The CRL0805-FW-R200ELF is a 200 mOhms ±1% thick film chip resistor manufactured by Bourns Inc. in the 0805 (2012 Metric) package format. This component is rated for 0.25W (1/4W) power dissipation and operates across the temperature range of -55°C to 125°C. The part is currently in active production status and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, supply chain considerations, or specific application requirements while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitute parts for the CRL0805-FW-R200ELF are qualified based on the following criteria:

Primary Matching Parameters:

• Resistance value: 200 mOhms
• Tolerance: ±1%
• Package format: 0805 (2012 Metric)
• Composition: Thick Film
• Termination count: 2

Secondary Compatibility Parameters:

• Operating temperature range: minimum -55°C, maximum ≥125°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1 (Unlimited)
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)

Substitutes are grouped into two categories based on power rating alignment and additional features. Parts with matching or higher power ratings and equivalent thermal specifications are considered direct substitutes. Parts with lower power ratings or enhanced feature sets are noted for application-specific evaluation.

Parameter Comparison

Engineering Selection Recommendations

CSR0805FKR200 (Stackpole Electronics Inc): This substitute maintains identical electrical specifications to the primary part, including 200 mOhms resistance, ±1% tolerance, and 0.25W power rating. The CSR series is designated for current sense applications with equivalent temperature coefficient performance. Operating temperature range extends to 155°C, providing additional thermal margin. ROHS3 compliance and MSL 1 rating match the primary part. Height specification is 0.026" (0.65mm), representing a 0.002" increase from the primary part. This substitute is suitable for direct replacement in applications where current sense functionality is beneficial or neutral.

RL0805FR-070R2L (YAGEO): This substitute provides 200 mOhms resistance and ±1% tolerance in the 0805 package with ROHS3 compliance and MSL 1 rating. The part is qualified to AEC-Q200 automotive standards and incorporates current sense and moisture-resistant features. Operating temperature range extends to 155°C. The power rating is 0.125W (1/8W), representing a 50% reduction from the primary part specification. Temperature coefficient is ±600ppm/°C, three times higher than the primary part. Physical height matches the primary part at 0.024" (0.60mm). This substitute is applicable only in applications where the reduced power rating and higher temperature coefficient are acceptable within circuit design margins.

Frequently Asked Questions (FAQ)

Q: Can CSR0805FKR200 be used as a direct replacement for CRL0805-FW-R200ELF?

A: Yes. Both parts share identical resistance (200 mOhms), tolerance (±1%), power rating (0.25W), package format (0805), and composition (thick film). Temperature coefficient and operating range are equivalent. The 0.002" height difference (0.026" vs 0.024") is within standard PCB assembly tolerances for 0805 components.

Q: What are the limitations of RL0805FR-070R2L as a substitute?

A: The RL0805FR-070R2L has a reduced power rating of 0.125W compared to the primary part's 0.25W specification. Additionally, the temperature coefficient is ±600ppm/°C versus ±200ppm/°C for the primary part. These differences require circuit-level analysis to confirm acceptability in the specific application. The part is suitable only when power dissipation remains below 0.125W and temperature coefficient drift is within design tolerance.

Q: Are all three parts mechanically compatible in the same PCB footprint?

A: Yes. All three parts use the 0805 (2012 Metric) package with identical length (0.079") and width (0.049") dimensions. Height variations (0.024" to 0.026") are within standard 0805 component specifications and do not affect PCB footprint compatibility.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All three parts are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and are in active production status. REACH status is unaffected for all parts, and all carry the same ECCN (EAR99) and HTSUS (8533.21.0030) classifications.

Q: Which substitute offers the widest operating temperature range?

A: Both CSR0805FKR200 and RL0805FR-070R2L extend the operating temperature range to -55°C ~ 155°C, compared to the primary part's -55°C ~ 125°C specification. This provides an additional 30°C of high-temperature operation capability.
