Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F1741CS is determined by strict equivalence across the following critical parameters:

• Resistance value: 1.74 kOhms
• Tolerance: ±1%
• Package / Case: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Number of Terminations: 2
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts are categorized as follows:

Direct Equivalent: Parts with identical electrical specifications, power rating (0.063W), and packaging. These provide one-to-one replacement capability without design modification.

Upgrade Equivalent: Parts with superior power rating (0.1W vs. 0.063W) while maintaining all other core specifications. These offer enhanced thermal margin and are suitable for direct substitution with improved reliability characteristics.

Similar Equivalent: Parts meeting all core electrical and mechanical specifications but with additional features such as automotive AEC-Q200 qualification or anti-sulfur construction. These are suitable for applications requiring enhanced environmental or automotive performance.

Parameter Comparison

Engineering Selection Recommendations

For Standard Applications (ROHS3 Compliant Required):

RC0402FR-071K74L (YAGEO) serves as the primary direct equivalent with identical electrical and mechanical specifications. This part maintains full compatibility with the original RC1005F1741CS across all critical parameters and carries ROHS3 compliance certification.

For Enhanced Thermal Performance:

ERJ-2RKF1741X (Panasonic Electronic Components) provides an upgrade path with 0.1W power rating versus the original 0.063W specification. This higher power rating offers improved thermal margin while maintaining all other core specifications. The part carries Automotive AEC-Q200 qualification and ROHS3 compliance.

For Automotive and Environmental Robustness:

AF0402FR-071K74L (YAGEO), CRCW04021K74FKED (Vishay Dale), and RMCF0402FT1K74 (Stackpole Electronics Inc) are suitable for applications requiring Automotive AEC-Q200 qualification. AF0402FR-071K74L additionally features anti-sulfur construction. All three maintain ROHS3 compliance and identical electrical specifications to the original part.

Parts to Avoid:

CRCW04021K74FKTD (Vishay Dale) does not carry ROHS3 compliance and is marked as RoHS non-compliant with REACH Affected status. This part is unsuitable for applications requiring regulatory compliance with current environmental standards.

Frequently Asked Questions (FAQ)

Q: Can RC0402FR-071K74L be used as a direct replacement for RC1005F1741CS?

A: Yes. RC0402FR-071K74L meets all electrical and mechanical specifications of the original part, including resistance value, tolerance, power rating, package format, temperature coefficient, and operating temperature range. Both parts carry ROHS3 compliance and MSL 1 rating.

Q: What is the advantage of using ERJ-2RKF1741X over the original part?

A: ERJ-2RKF1741X provides a higher power rating of 0.1W compared to the original 0.063W specification. This upgrade allows for greater thermal headroom in the application while maintaining all other electrical characteristics. The part also carries Automotive AEC-Q200 qualification.

Q: Are automotive-qualified parts (AEC-Q200) compatible with non-automotive applications?

A: Yes. Automotive AEC-Q200 qualified parts meet or exceed the electrical and reliability requirements of standard industrial-grade components. These parts are suitable for any application where the original part was specified, with the added benefit of enhanced qualification testing.

Q: What is the difference between the two Vishay Dale variants (CRCW04021K74FKED and CRCW04021K74FKTD)?

A: Both parts are electrically and mechanically identical. The primary difference is regulatory compliance: CRCW04021K74FKED carries ROHS3 compliance, while CRCW04021K74FKTD does not. For new designs and applications requiring environmental compliance, CRCW04021K74FKED is the appropriate selection.

Q: Does the 0402 package format remain consistent across all substitute parts?

A: Yes. All substitute parts listed maintain the 0402 (1005 Metric) package format with identical physical dimensions (0.039" L x 0.020" W / 1.00mm x 0.50mm) and maximum seated height specifications. This ensures PCB layout and assembly compatibility without modification.

Q: Are there packaging format differences between substitute parts?

A: Most substitute parts are supplied in Tape & Reel (TR) format, matching the original RC1005F1741CS packaging. ERJ-2RKF1741X is supplied in Cut Tape (CT) & Digi-Reel format. Both packaging formats are standard for 0402 components and do not affect electrical performance or PCB assembly compatibility.

Q: What is the significance of the ±100ppm/°C temperature coefficient across all parts?

A: The temperature coefficient specification indicates the resistance value change per degree Celsius across the operating temperature range. All listed parts maintain identical ±100ppm/°C specification, ensuring consistent thermal behavior and circuit performance across -55°C to 155°C operating conditions.
