RC1005F3922CS – 39.2kΩ ±1% 1/16W 0402 Chip Resistor Equivalent & Substitute Parts

Part Overview

The RC1005F3922CS is a 39.2 kOhms ±1% thick film chip resistor in 0402 (1005 Metric) package manufactured by Samsung Electro-Mechanics. This surface-mount resistor is rated for 0.063W (1/16W) power dissipation with a temperature coefficient of ±100ppm/°C and operating range of -55°C to 155°C. The component is ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level) and features moisture-resistant characteristics. Alternative manufacturers' equivalents are necessary to ensure supply continuity, support design flexibility across multiple qualification requirements, and address potential lead time constraints from primary sources.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-3922GLF directly replace RC1005F3922CS? A: Yes. Both components share identical resistance (39.2 kΩ), tolerance (±1%), power rating (0.063W), package (0402), and temperature specifications (-55°C to 155°C). Full pin-to-pin compatibility is confirmed.

Q: What is the difference between the main part and ERJ-2RKF3922X? A: The primary electrical and thermal parameters remain identical. ERJ-2RKF3922X features a higher power rating (0.1W vs. 0.063W) and carries automotive AEC-Q200 certification, making it suitable for applications requiring enhanced reliability margins or automotive supply chain qualification.

Q: Are moisture-resistant versions required? A: The RC1005F3922CS includes moisture-resistant characteristics. YAGEO RC0402FR-0739K2L maintains this feature. Bourns CR0402-FX-3922GLF does not list moisture resistance; assembly process verification is necessary if moisture ingress protection is a design requirement.

Q: Can I use automotive-qualified parts in non-automotive designs? A: Yes. Automotive AEC-Q200 qualified resistors (RMCF0402FT39K2, AC0402FR-0739K2L, CRCW040239K2FKED) meet or exceed commercial specifications. Their use improves reliability margins with no performance penalties.

Q: Why is CRCW040239K2FKTD marked as non-recommended? A: This variant carries RoHS non-compliance status. Selection of this part invalidates ROHS3 compliance claims for end assemblies and is incompatible with regulatory requirements for most industrial and consumer electronics applications.

Q: What packaging format considerations apply to these substitutes? A: RC1005F3922CS and most alternatives use Tape & Reel (TR) packaging. MCR01MRTF3922 uses Cut Tape (CT) & Digi-Reel format; assembly equipment must support this format before selection. Tape format differences do not affect electrical or mechanical performance.

Q: Are all active-status parts suitable for new designs? A: All active-status parts listed meet current design requirements. MCR01MRTF3922, though currently stocked, is discontinued at the distributor level and should not be selected for new designs requiring long-term supply assurance.
