Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1005F4220CS are classified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Core Matching Parameters:

• Resistance value: 422 Ohms
• Tolerance: ±1%
• Package format: 0402 (1005 Metric)
• Physical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Composition: Thick Film
• RoHS3 compliance
• MSL 1 rating

Substitution Categories:

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

Upgrade Substitutes provide higher power rating (0.1W, 1/10W) while maintaining all other electrical parameters. These parts support applications requiring increased power dissipation capability.

Similar Substitutes include automotive-grade AEC-Q200 certification in addition to base electrical specifications. These parts meet automotive reliability standards and may include enhanced moisture resistance features.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Selection:

CR0402-FX-4220GLF (Bourns Inc.) and RC0402FR-07422RL (YAGEO) function as direct electrical equivalents to the RC1005F4220CS. Both maintain identical resistance, tolerance, power rating, and temperature specifications. RC0402FR-07422RL includes moisture resistant characteristics matching the original part. Selection between these options depends on packaging preference (Tape & Reel versus Cut Tape) and supply availability.

Upgrade Path:

ERJ-2RKF4220X (Panasonic Electronic Components) provides increased power rating (0.1W versus 0.063W) while maintaining all other electrical parameters. This part includes AEC-Q200 automotive qualification. Selection of this upgrade is appropriate for applications requiring higher power dissipation margin or automotive-grade reliability standards.

Automotive-Grade Alternatives:

AC0402FR-07422RL (YAGEO), CRCW0402422RFKED (Vishay Dale), and RMCF0402FT422R (Stackpole Electronics Inc.) incorporate AEC-Q200 automotive qualification with identical electrical specifications to the main part. AC0402FR-07422RL additionally includes moisture resistant features. These parts are suitable for automotive applications or designs requiring enhanced reliability certification.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and identical operating temperature range (-55°C ~ 155°C). Selection criteria should prioritize supply chain availability, packaging format requirements, and application-specific compliance needs.
