CAR0805-220KB1 Equivalent & Substitute Parts

Part Overview

The CAR0805-220KB1 is a 220 kOhms ±0.1% thin film chip resistor in 0805 (2012 Metric) package rated at 0.1W (1/10W) power dissipation. Manufactured by Riedon, this component is active and in production. Substitute parts are identified when design requirements allow for equivalent electrical performance within the same package footprint and tolerance specification, or when upgraded specifications provide enhanced reliability for specific applications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Direct Equivalents maintain identical electrical specifications: 220 kOhms resistance, ±0.1% tolerance, 0.1W power rating, 0805 package, thin film composition, ±25ppm/°C temperature coefficient, and -55°C ~ 155°C operating range.

Upgraded Substitutes provide enhanced specifications while maintaining core electrical parameters (220 kOhms, ±0.1% tolerance, 0805 package, thin film composition). Upgrades include increased power ratings (0.125W or 0.26W), automotive AEC-Q200 certification, anti-sulfur features, or extended temperature ranges. These parts are electrically compatible and physically interchangeable in the same PCB footprint.

All substitute parts share identical resistance value, tolerance, package dimensions, and termination count with the main part.

Engineering Selection Recommendations

Direct Equivalent Selection: CPF0805B220KE1 from TE Connectivity Passive Product provides identical electrical and mechanical specifications to the CAR0805-220KB1. This part is suitable for applications where the original specification must be maintained without modification.

Upgraded Selection for Automotive Applications: ERA-6AEB224V (Panasonic) and RG2012P-224-B-T5 (Susumu) both carry AEC-Q200 automotive qualification. These parts feature 0.125W power rating and are appropriate for automotive-grade circuit designs. RG2012P-224-B-T5 includes anti-sulfur protection.

Upgraded Selection for High-Reliability Applications: TNPW0805220KBEEA from Vishay Dale offers the highest power rating (0.26W), extended operating temperature range (-55°C ~ 175°C), AEC-Q200 automotive qualification, anti-sulfur protection, and moisture-resistant construction. This part is suitable for demanding environments and applications requiring enhanced thermal margin.

General Upgrade Path: RT0805BRD07220KL from YAGEO provides 0.125W power rating as a straightforward upgrade from the 0.1W specification while maintaining all other electrical parameters.

All substitute parts maintain ROHS3 compliance and MSL 1 rating identical to the main part.

Frequently Asked Questions (FAQ)

Q: Can CPF0805B220KE1 be used as a direct replacement for CAR0805-220KB1?

A: Yes. CPF0805B220KE1 matches all electrical specifications (220 kOhms, ±0.1%, 0.1W) and physical dimensions (0805 package). No circuit modifications are required.

Q: What is the difference between the 0.1W and 0.125W power ratings?

A: The 0.125W (1/8W) rated parts provide 25% additional power dissipation capacity compared to 0.1W (1/10W) parts. In applications where the original 0.1W specification is adequate, either rating is acceptable. Higher power ratings provide thermal margin but do not change electrical performance.

Q: Are the automotive AEC-Q200 qualified parts suitable for non-automotive applications?

A: Yes. AEC-Q200 qualification indicates enhanced reliability testing and quality standards. These parts are fully compatible with non-automotive designs and provide equivalent or superior performance.

Q: What does anti-sulfur protection mean?

A: Anti-sulfur protection prevents degradation of component performance in environments with hydrogen sulfide exposure. This feature is relevant for industrial and harsh environment applications. For standard indoor electronics, this feature provides no functional difference.

Q: Can I use TNPW0805220KBEEA in place of CAR0805-220KB1?

A: Yes. TNPW0805220KBEEA is electrically and mechanically compatible. It provides upgraded specifications including higher power rating (0.26W), extended temperature range (-55°C ~ 175°C), and additional protective features. No circuit modifications are required.

Q: Do all substitute parts have the same physical dimensions?

A: All parts share the same 0805 (2012 Metric) package footprint (0.079" L x 0.049" W). Height variations are minor (0.020" to 0.026" seated height) and do not affect PCB assembly compatibility.

Q: What is MSL 1 rating?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture baking requirements. All listed parts carry MSL 1 rating, requiring no special storage or handling procedures.
