Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1005F3831CS are classified based on strict electrical and mechanical parameter matching. All identified substitutes maintain the following core specifications:

Critical Matching Parameters:

• Resistance value: 3.83 kOhms
• Tolerance: ±1%
• Package format: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• Number of terminations: 2

Substitution Categories:

Direct Equivalents maintain identical power ratings (0.063W / 1/16W) and packaging specifications. These parts are fully interchangeable without circuit modification.

Upgrade Substitutes feature enhanced power ratings (0.1W / 1/10W) while maintaining all other electrical and mechanical parameters. These parts provide additional thermal margin and are suitable for applications requiring higher power dissipation capability.

Automotive-Qualified Substitutes include AEC-Q200 certification in addition to standard specifications. These parts meet automotive industry reliability standards and are suitable for both general-purpose and automotive applications.

Engineering Selection Recommendations

For ROHS3-Compliant Applications: CR0402-FX-3831GLF (Bourns Inc.), RC0402FR-073K83L (YAGEO), ERJ-2RKF3831X (Panasonic), AC0402FR-073K83L (YAGEO), CRCW04023K83FKED (Vishay Dale), and RMCF0402FT3K83 (Stackpole Electronics Inc) are all suitable direct substitutes with full ROHS3 compliance matching the original RC1005F3831CS specification.

For Moisture-Resistant Applications: RC0402FR-073K83L (YAGEO) and AC0402FR-073K83L (YAGEO) explicitly feature moisture resistance, matching the environmental protection of the original part. AC0402FR-073K83L additionally provides AEC-Q200 automotive qualification.

For Automotive Applications: ERJ-2RKF3831X (Panasonic), AC0402FR-073K83L (YAGEO), CRCW04023K83FKED (Vishay Dale), and RMCF0402FT3K83 (Stackpole Electronics Inc) carry AEC-Q200 certification. ERJ-2RKF3831X provides enhanced power rating (0.1W) for applications requiring additional thermal headroom.

For Non-Automotive Applications with Standard Requirements: CR0402-FX-3831GLF (Bourns Inc.) offers a direct equivalent without automotive qualification, suitable for general-purpose consumer and industrial applications.

Compliance Consideration: CRCW04023K83FKTD (Vishay Dale) is RoHS non-compliant and REACH-affected. This part is not suitable for applications requiring ROHS3 compliance or REACH compliance.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC1005F3831CS with any of the listed parts without circuit modification?

A: Yes, all ROHS3-compliant parts listed maintain identical electrical specifications (3.83 kOhms ±1%, 0.063W, ±100ppm/°C) and mechanical dimensions (0402 package). Direct substitution is possible. ERJ-2RKF3831X features a higher power rating (0.1W) and remains functionally compatible as it exceeds the original specification.

Q: What is the difference between direct equivalents and upgrade substitutes?

A: Direct equivalents maintain the original 0.063W (1/16W) power rating. The upgrade substitute ERJ-2RKF3831X provides 0.1W (1/10W) power rating, offering greater thermal margin. Both are electrically and mechanically compatible with the original circuit design.

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

A: Yes. Automotive-qualified parts (AEC-Q200) meet stringent reliability and environmental standards that exceed general-purpose requirements. These parts are fully suitable for non-automotive applications and provide enhanced reliability margins.

Q: What packaging options are available?

A: Substitute parts are available in two packaging formats: Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel. Both formats contain identical components; packaging selection depends on assembly process requirements and order quantities.

Q: Why is CRCW04023K83FKTD listed if it is RoHS non-compliant?

A: CRCW04023K83FKTD is included for reference purposes only. This part is not recommended for new designs or applications requiring ROHS3 compliance. It is listed to prevent accidental selection and to document its non-compliant status.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All listed parts, including the original RC1005F3831CS, maintain Moisture Sensitivity Level 1 (Unlimited), indicating no moisture-related handling restrictions during storage or assembly.

Q: Can I use RC0402FR-073K83L as a direct replacement for moisture-sensitive applications?

A: Yes. RC0402FR-073K83L explicitly features moisture resistance and maintains MSL 1 rating, making it suitable for applications requiring environmental protection equivalent to the original part.

Q: What is the temperature coefficient significance in resistor selection?

A: All listed parts maintain ±100ppm/°C temperature coefficient across the -55°C to 155°C operating range. This specification ensures consistent resistance value stability across temperature variations, maintaining circuit performance within design tolerances.
