Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1005F4422CS are classified based on strict electrical and mechanical parameter alignment. All substitute candidates maintain the following core parameters: 44.2 kOhms resistance value, ±1% tolerance, 0402 (1005 Metric) package, thick film composition, ±100ppm/°C temperature coefficient, -55°C to 155°C operating temperature range, MSL Level 1, ROHS3 compliance, and 2 terminations.

Direct Substitutes share identical electrical specifications and power rating (0.063W / 1/16W):

• CR0402-FX-4422GLF (Bourns Inc.)
• RC0402FR-0744K2L (YAGEO)

Upgrade Substitute provides enhanced power rating (0.1W / 1/10W) while maintaining all other electrical parameters:

• ERJ-2RKF4422X (Panasonic Electronic Components)

Similar Substitutes include automotive AEC-Q200 qualification in addition to base electrical specifications:

• AC0402FR-0744K2L (YAGEO)
• CRCW040244K2FKED (Vishay Dale)
• RMCF0402FT44K2 (Stackpole Electronics Inc)

Substitution eligibility is determined by matching resistance, tolerance, package format, composition, temperature coefficient, operating temperature range, and compliance certifications. Power rating may be equal or higher. Automotive qualification (AEC-Q200) is an additional feature that does not preclude substitution in non-automotive applications.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): CR0402-FX-4422GLF and RC0402FR-0744K2L are functionally equivalent to RC1005F4422CS. Both maintain identical electrical parameters, package format, and compliance certifications. RC0402FR-0744K2L includes moisture resistance matching the original part. Selection between these options depends on packaging preference (Tape & Reel versus Cut Tape & Digi-Reel) and supplier availability.

For Enhanced Power Dissipation: ERJ-2RKF4422X provides a higher power rating (0.1W versus 0.063W) while maintaining all other electrical specifications. This upgrade option is suitable for applications requiring additional thermal margin. The part carries Panasonic's automotive AEC-Q200 qualification, which does not restrict use in non-automotive applications.

For Automotive Applications: AC0402FR-0744K2L, CRCW040244K2FKED, and RMCF0402FT44K2 are qualified to automotive AEC-Q200 standard. These parts are suitable for automotive and industrial applications requiring enhanced reliability qualification. AC0402FR-0744K2L additionally includes moisture resistance. Selection among these three depends on supplier availability and packaging requirements.

Compliance Verification: All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and REACH unaffected status. No additional compliance verification is required for substitution.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-4422GLF be used as a direct replacement for RC1005F4422CS? A: Yes. CR0402-FX-4422GLF matches all critical electrical parameters: 44.2 kOhms resistance, ±1% tolerance, 0.063W power rating, 0402 package, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. Both are ROHS3 compliant with MSL Level 1. The primary difference is that CR0402-FX-4422GLF does not specify moisture resistance as a feature, whereas RC1005F4422CS does.

Q: What is the difference between the direct substitutes and the upgrade substitute? A: Direct substitutes (CR0402-FX-4422GLF and RC0402FR-0744K2L) maintain the 0.063W power rating. The upgrade substitute ERJ-2RKF4422X provides 0.1W power rating, offering higher thermal capacity. All other electrical specifications remain identical. The upgrade is suitable for applications with higher power dissipation requirements.

Q: Are automotive-qualified parts (AEC-Q200) suitable for non-automotive applications? A: Yes. Automotive AEC-Q200 qualification indicates enhanced reliability and quality standards. Parts meeting this standard are fully compatible with non-automotive applications and may provide additional design margin.

Q: Does package format differ among substitute parts? A: All substitute parts use the 0402 (1005 Metric) package format. Packaging type (Tape & Reel versus Cut Tape & Digi-Reel) varies by manufacturer and supplier but does not affect electrical compatibility. Packaging selection depends on assembly process requirements and supplier availability.

Q: Can RC0402FR-0744K2L replace RC1005F4422CS in moisture-sensitive applications? A: Yes. RC0402FR-0744K2L explicitly includes moisture resistance as a feature, matching the original part's moisture-resistant specification. Both components carry MSL Level 1 (unlimited) rating, indicating no moisture sensitivity restrictions.

Q: What is the significance of the ±100ppm/°C temperature coefficient? A: The temperature coefficient indicates resistance value change per degree Celsius across the operating temperature range. All substitute parts maintain ±100ppm/°C, ensuring identical temperature stability performance across the -55°C to 155°C operating range.

Q: Are there any height or dimensional differences among substitute parts? A: Seated height specifications are consistent across all parts at 0.016" (0.40mm) maximum, with AC0402FR-0744K2L specified at 0.015" (0.37mm). All parts maintain identical length and width dimensions of 0.039" L x 0.020" W (1.00mm x 0.50mm). These minor variations do not affect PCB layout or assembly compatibility.
