Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F4223CS is determined by strict equivalence across the following critical parameters: resistance value (422 kOhms), tolerance (±1%), package format (0402 / 1005 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, REACH Unaffected, EAR99).

The substitute parts are categorized as follows:

Direct Equivalents maintain identical electrical specifications and power rating (0.063W / 1/16W). These parts are pin-compatible, footprint-compatible, and functionally interchangeable without circuit modification.

Upgrade Substitute (ERJ-2RKF4223X) provides higher power rating (0.1W / 1/10W) while maintaining all other electrical parameters. This part is suitable for applications where increased thermal margin is beneficial and does not create design conflicts.

Similar Substitutes include automotive-grade AEC-Q200 qualified parts that match all electrical specifications and power rating but add automotive qualification features. These are suitable for applications requiring automotive-grade reliability without design modification.

All substitute parts share identical package dimensions (0.039" L x 0.020" W / 1.00mm x 0.50mm), maximum seated height (0.016" / 0.40mm), and termination count (2), ensuring mechanical and electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: CR0402-FX-4223GLF (Bourns Inc.) and RC0402FR-07422KL (YAGEO) are functionally identical to the RC1005F4223CS. Both maintain the same electrical specifications, power rating, package format, and compliance certifications. Selection between these direct equivalents depends on inventory availability and supply chain logistics.

For Thermal Margin Enhancement: ERJ-2RKF4223X (Panasonic Electronic Components) provides 0.1W power rating compared to the 0.063W of the main part, while maintaining all other electrical parameters. This upgrade substitute is appropriate for applications where increased power dissipation capability or thermal headroom is advantageous. The higher power rating does not create design conflicts in circuits designed for the lower-rated part.

For Automotive Applications: CRCW0402422KFKED (Vishay Dale) and RMCF0402FT422K (Stackpole Electronics Inc) are AEC-Q200 qualified automotive-grade alternatives. These parts are suitable for automotive and industrial applications requiring automotive-grade reliability certification. Both maintain identical electrical specifications and power rating to the main part.

All substitute parts are Active products with ROHS3 compliance, REACH Unaffected status, and EAR99 classification, matching the regulatory and compliance profile of the RC1005F4223CS.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-4223GLF be used as a direct replacement for RC1005F4223CS without circuit modification?

A: Yes. CR0402-FX-4223GLF is a direct equivalent with identical resistance (422 kOhms), tolerance (±1%), power rating (0.063W), package format (0402), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). No circuit modification is required.

Q: What is the difference between the main part and the upgrade substitute ERJ-2RKF4223X?

A: The primary difference is power rating. ERJ-2RKF4223X is rated at 0.1W (1/10W) compared to 0.063W (1/16W) for RC1005F4223CS. All other electrical parameters are identical. The higher power rating provides increased thermal capability and is suitable for applications requiring additional thermal margin.

Q: Are the automotive-grade substitutes (CRCW0402422KFKED and RMCF0402FT422K) compatible with non-automotive applications?

A: Yes. Automotive-grade parts meet or exceed the specifications of standard industrial-grade parts. AEC-Q200 qualification ensures higher reliability standards. These parts are fully compatible with non-automotive applications and provide enhanced reliability.

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

A: Yes. All parts listed maintain identical package format (0402 / 1005 Metric), dimensions (0.039" L x 0.020" W / 1.00mm x 0.50mm), maximum seated height (0.016" / 0.40mm), and termination count (2). Footprints are mechanically and electrically identical.

Q: What is the moisture sensitivity level for all listed parts?

A: All parts, including the main part and all substitutes, have Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life without moisture control requirements.

Q: Are all substitute parts available in Tape & Reel (TR) packaging?

A: Yes. All substitute parts listed are supplied in Tape & Reel (TR) packaging, matching the packaging format of the RC1005F4223CS.
