Key Parameters

Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on electrical and mechanical compatibility:

Direct Equivalent (RC0402FR-0727R4L): Identical electrical specifications including 27.4 Ohms resistance, ±1% tolerance, 0.063W power rating, and 0402 package. Differs only in manufacturer (YAGEO) and series designation (RC_L). Maintains all compliance certifications and operating parameters.

Upgrade Equivalent (ERJ-2RKF27R4X): Matches all electrical specifications with identical resistance, tolerance, temperature coefficient, and operating temperature range. Differs in power rating (0.1W vs. 0.063W) and includes automotive AEC-Q200 qualification. Higher power rating provides enhanced thermal margin in the same 0402 package footprint.

Similar Equivalents (AC0402FR-0727R4L, CRCW040227R4FKED, RMCF0402FT27R4): All maintain identical electrical specifications (27.4 Ohms ±1%, 0.063W, ±100ppm/°C). Differ in manufacturer, series designation, and packaging format. AC0402FR-0727R4L and RMCF0402FT27R4 include automotive AEC-Q200 qualification. CRCW040227R4FKED uses Cut Tape (CT) & Digi-Reel® packaging instead of Tape & Reel (TR).

Substitution logic is based on: identical resistance value, tolerance, temperature coefficient, operating temperature range, package dimensions, and number of terminations. Power rating equivalence allows upgrade substitution when higher ratings are acceptable.

Parameter Comparison

Engineering Selection Recommendations

RC0402FR-0727R4L (YAGEO): Direct equivalent substitute with identical electrical and mechanical specifications. Suitable for applications requiring standard industrial-grade thick film resistors without automotive qualification requirements. Active product status with high inventory availability (810,092 pcs).

ERJ-2RKF27R4X (Panasonic): Upgrade substitute with enhanced power rating (0.1W vs. 0.063W) and automotive AEC-Q200 qualification. Appropriate for applications requiring higher thermal margin or automotive-grade reliability. Maintains identical electrical performance with improved thermal characteristics in the same 0402 footprint.

AC0402FR-0727R4L (YAGEO): Similar substitute with automotive AEC-Q200 qualification and moisture-resistant features. Identical electrical specifications and 0402 package. Suitable for automotive and industrial applications requiring AEC-Q200 compliance. Slightly lower seated height (0.015" vs. 0.016").

CRCW040227R4FKED (Vishay Dale): Similar substitute with automotive AEC-Q200 qualification. Differs in packaging format (Cut Tape & Digi-Reel® vs. Tape & Reel). Suitable for applications where alternative packaging is acceptable and automotive qualification is required.

RMCF0402FT27R4 (Stackpole Electronics): Similar substitute with automotive AEC-Q200 qualification. Identical electrical specifications and Tape & Reel packaging. Highest inventory availability (415,660 pcs) among similar equivalents. Suitable for high-volume applications requiring automotive-grade components.

All substitute parts maintain RoHS3 compliance, MSL 1 rating, and identical operating temperature range (-55°C ~ 155°C). Selection should be based on application requirements for automotive qualification, packaging format preference, and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can RC0402FR-0727R4L replace RC1005F27R4CS in all applications?

A: Yes. RC0402FR-0727R4L is a direct equivalent with identical resistance (27.4 Ohms), tolerance (±1%), power rating (0.063W), package (0402), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). Both are RoHS3 compliant with MSL 1 rating. Substitution is electrically and mechanically compatible.

Q: What is the difference between the main part and ERJ-2RKF27R4X?

A: ERJ-2RKF27R4X is an upgrade substitute with identical electrical specifications but higher power rating (0.1W vs. 0.063W). It includes automotive AEC-Q200 qualification, which the original RC1005F27R4CS does not have. The higher power rating provides enhanced thermal margin while maintaining the same 0402 package dimensions.

Q: Are the automotive AEC-Q200 qualified parts (AC0402FR-0727R4L, CRCW040227R4FKED, RMCF0402FT27R4, ERJ-2RKF27R4X) interchangeable with the non-automotive RC1005F27R4CS?

A: Electrically and mechanically, yes. All maintain identical resistance, tolerance, temperature coefficient, and operating temperature range. However, automotive-qualified parts include additional qualification testing and reliability documentation. Use automotive-qualified substitutes when application requirements specify AEC-Q200 compliance or when enhanced reliability documentation is required.

Q: Does packaging format affect substitution compatibility?

A: Packaging format (Tape & Reel vs. Cut Tape & Digi-Reel®) affects handling and assembly processes but not electrical or mechanical compatibility. CRCW040227R4FKED uses Cut Tape & Digi-Reel® packaging while others use Tape & Reel (TR). Verify packaging compatibility with assembly equipment before selection.

Q: What is the significance of the height difference between AC0402FR-0727R4L (0.015") and other parts (0.016")?

A: AC0402FR-0727R4L has a maximum seated height of 0.015" (0.37mm) compared to 0.016" (0.40mm) for other parts. This 0.001" difference is within typical PCB design tolerances and does not affect functional compatibility. Verify clearance requirements in specific applications with tight height constraints.

Q: Which substitute part has the highest inventory availability?

A: RMCF0402FT27R4 (Stackpole Electronics) has the highest inventory with 415,660 pcs available. RC0402FR-0727R4L (YAGEO) has 810,092 pcs. Both are suitable for high-volume production requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (RC0402FR-0727R4L, ERJ-2RKF27R4X, AC0402FR-0727R4L, CRCW040227R4FKED, RMCF0402FT27R4) are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original RC1005F27R4CS specifications.
