Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Functionally Equivalent):

CR0402-FX-33R2GLF (Bourns Inc.) is a direct substitute with identical electrical specifications, power rating, and package format. This part maintains ROHS3 compliance and operates within the same temperature range. Selection is appropriate for applications where moisture resistance is not a design requirement.

RC0402FR-0733R2L (YAGEO) is a direct substitute offering moisture resistant characteristics matching the original part. ROHS3 compliance and identical electrical parameters support seamless integration. This part is available in Cut Tape & Digi-Reel® packaging format.

Upgrade Substitute (Enhanced Capability):

ERJ-2RKF33R2X (Panasonic Electronic Components) provides upgraded power rating of 0.1W (1/10W) compared to the 0.063W specification of the original part. This higher power rating accommodates applications with increased thermal stress while maintaining all other electrical parameters. Automotive AEC-Q200 qualification is included. Selection is appropriate when enhanced reliability margin is required.

Similar Substitutes (Application-Specific Features):

AC0402FR-0733R2L (YAGEO) combines moisture resistant properties with automotive AEC-Q200 qualification. This part is suitable for automotive and harsh environment applications requiring both environmental protection and automotive-grade reliability.

AF0402FR-0733R2L (YAGEO) adds anti-sulfur protection in addition to automotive AEC-Q200 qualification. Selection is appropriate for applications exposed to sulfur-containing environments or requiring enhanced corrosion resistance.

CRCW040233R2FKED (Vishay Dale) provides automotive AEC-Q200 qualification with ROHS3 compliance in Cut Tape & Digi-Reel® packaging. This part supports automotive applications with standard environmental protection.

RMCF0402FT33R2 (Stackpole Electronics Inc) offers automotive AEC-Q200 qualification with ROHS3 compliance. This part is suitable for automotive circuit applications requiring qualified component status.

Non-Recommended:

CRCW040233R2FKTD (Vishay Dale) does not meet current compliance requirements. This part is RoHS non-compliant and REACH affected, making it unsuitable for new designs or applications with regulatory compliance mandates.

Frequently Asked Questions (FAQ)

Q: Can ERJ-2RKF33R2X be used as a direct replacement for RC1005F33R2CS?

A: ERJ-2RKF33R2X is functionally compatible as a substitute. The higher power rating (0.1W vs. 0.063W) is an upgrade that does not create compatibility issues. All other electrical parameters including resistance, tolerance, temperature coefficient, and operating range are identical. The part is suitable for direct substitution in applications where the higher power rating does not create thermal or space constraints.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® packaging?

A: Tape & Reel (TR) packaging provides continuous reel format suitable for high-volume automated assembly. Cut Tape (CT) & Digi-Reel® packaging offers smaller quantity formats with individual tape segments, suitable for lower-volume production or prototype applications. Both formats contain identical components; packaging selection depends on production volume and assembly equipment compatibility.

Q: Are automotive AEC-Q200 qualified parts required for non-automotive applications?

A: Automotive AEC-Q200 qualification is not required for non-automotive applications. However, AEC-Q200 qualified parts (AC0402FR-0733R2L, AF0402FR-0733R2L, CRCW040233R2FKED, RMCF0402FT33R2) undergo additional reliability testing and are suitable for any application requiring enhanced quality assurance. Selection of AEC-Q200 parts for non-automotive use provides additional design margin without penalty.

Q: What does moisture resistant mean for chip resistors?

A: Moisture resistant thick film resistors (RC1005F33R2CS, RC0402FR-0733R2L, AC0402FR-0733R2L, AF0402FR-0733R2L) incorporate protective coatings that reduce moisture absorption and improve performance stability in humid environments. This feature is beneficial for applications exposed to high humidity, condensation, or moisture-prone conditions. Non-moisture-resistant parts (CR0402-FX-33R2GLF) are suitable for controlled environment applications.

Q: Is ROHS3 compliance mandatory for all substitute parts?

A: ROHS3 compliance is mandatory for applications subject to European Union Restriction of Hazardous Substances regulations. All recommended substitute parts except CRCW040233R2FKTD maintain ROHS3 compliance. CRCW040233R2FKTD is excluded from recommendations due to non-compliance status.

Q: Can parts with different height specifications be used interchangeably?

A: All substitute parts maintain maximum seated height of 0.40mm or less, meeting the physical constraint of the original RC1005F33R2CS specification (0.40mm max). AC0402FR-0733R2L and AF0402FR-0733R2L specify 0.37mm maximum height, which is within tolerance. Physical interchangeability is confirmed across all recommended substitutes.

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

A: Temperature coefficient of ±100 ppm/°C indicates the maximum resistance change per degree Celsius across the operating temperature range. All substitute parts maintain this specification, ensuring consistent electrical performance across the -55°C to 155°C operating range. This parameter is critical for precision analog circuits and temperature-sensitive applications.
