CAR0805-220RB1 Equivalent & Substitute Parts

Part Overview

The CAR0805-220RB1 is a 220 Ohm ±0.1% thin film chip resistor in 0805 (2012 Metric) package rated at 0.1W (1/10W) power dissipation. Manufactured by Riedon and currently in active production status, this component is designed for precision applications requiring tight tolerance and stable performance across the operating temperature range of -55°C to 155°C. Substitute parts are identified when original inventory is unavailable, when design requirements permit higher power ratings, or when automotive-grade certifications are required for specific applications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Core Compatibility Requirements:

Resistance value: 220 Ohms
Tolerance: ±0.1%
Package: 0805 (2012 Metric)
Composition: Thin Film
Temperature Coefficient: ±25ppm/°C
Operating Temperature Range: -55°C to 155°C
RoHS3 Compliance
MSL Rating: 1 (Unlimited)

Power Rating Consideration: The CAR0805-220RB1 is rated at 0.1W. Substitute parts with equal or higher power ratings (0.125W or 0.25W) are electrically compatible and may be used in applications where the original part is unavailable. Higher power ratings provide additional thermal margin without affecting circuit performance at the specified operating conditions.

Automotive Certification: Some substitute parts carry AEC-Q200 automotive qualification. This certification is an additional feature and does not prevent use in non-automotive applications. Parts without AEC-Q200 remain fully compatible with the original specification.

Engineering Selection Recommendations

Direct Equivalent (Identical Specifications): CPF0805B220RE1 from TE Connectivity Passive Product is a direct equivalent with matching power rating (0.1W), identical tolerance (±0.1%), and equivalent physical dimensions. This part is suitable for one-to-one replacement without design modification.

Higher Power Rating Substitutes: RNCF0805BTE220R, ERA-6AEB221V, and RG2012P-221-B-T5 all feature increased power ratings (0.125W or 0.25W) while maintaining all other electrical specifications. These parts are compatible with the original design and provide additional thermal headroom. RNCF0805BTE220R and ERA-6AEB221V carry AEC-Q200 automotive qualification, suitable for applications requiring automotive-grade components.

Standard Thin Film Alternative: RT0805BRD07220RL from YAGEO meets all electrical specifications with 0.125W power rating and does not carry automotive certification, making it suitable for general industrial and consumer applications.

Compliance Status: All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and identical operating temperature range (-55°C to 155°C). All parts are currently in active production status.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with higher power rating than the original CAR0805-220RB1? A: Yes. The CAR0805-220RB1 is rated at 0.1W. Substitute parts rated at 0.125W or 0.25W are electrically compatible and will function correctly in the same circuit. Higher power ratings indicate greater thermal capacity and do not negatively affect circuit operation.

Q: What is the difference between AEC-Q200 and non-AEC-Q200 parts? A: AEC-Q200 is an automotive industry qualification standard. Parts carrying this certification have undergone additional reliability testing for automotive applications. Non-AEC-Q200 parts meet the same electrical specifications and are suitable for non-automotive applications. AEC-Q200 parts may be used in any application, automotive or otherwise.

Q: Are all substitute parts in the same 0805 package? A: Yes. All listed substitute parts use the 0805 (2012 Metric) package. Physical dimensions are equivalent, with minor variations in maximum seated height (0.020" to 0.026"). These variations are within standard PCB assembly tolerances and do not affect placement or solderability.

Q: Do substitute parts have the same tolerance as the original? A: Yes. All substitute parts maintain ±0.1% tolerance, matching the original CAR0805-220RB1 specification. Temperature coefficient is also identical at ±25ppm/°C across all parts.

Q: Which substitute part should I choose if I need automotive qualification? A: RNCF0805BTE220R, ERA-6AEB221V, and RG2012P-221-B-T5 all carry AEC-Q200 automotive certification. Selection among these three depends on availability, lead time, and specific design requirements such as anti-sulfur protection (available in RG2012P-221-B-T5).

Q: Is RoHS3 compliance maintained across all substitute parts? A: Yes. All substitute parts listed are ROHS3 compliant, matching the original part's environmental compliance status.
