Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS2012F44R2CS are qualified based on strict equivalence of the following parameters:

• Resistance Value: 44.2 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 0.125W / 1/8W (exact match required)
• Package Format: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• Compliance: ROHS3 Compliant, MSL 1, REACH Unaffected (exact match required)

All identified substitute parts meet these criteria. Variations in features (such as automotive AEC-Q200 certification or anti-sulfur treatment) represent additional capabilities that do not disqualify substitution but indicate enhanced specifications for specific application environments.

Parameter Comparison

Engineering Selection Recommendations

All four components listed—RCS2012F44R2CS, CRCW080544R2FKEA, ERJ-6ENF44R2V, and RC0805FR-0744R2L—are functionally equivalent for applications requiring a 44.2 Ohm ±1% 0.125W thick film resistor in 0805 package format. All components maintain Active product status and full compliance with ROHS3, REACH, and MSL 1 requirements.

Selection between these parts is determined by:

• Availability: Inventory levels vary across manufacturers. CRCW080544R2FKEA (Vishay Dale) and ERJ-6ENF44R2V (Panasonic) offer higher stock quantities (25,561 and 60,373 units respectively) compared to RCS2012F44R2CS (929 units) and RC0805FR-0744R2L (4,088 units).

• Application-Specific Certifications: CRCW080544R2FKEA and ERJ-6ENF44R2V include Automotive AEC-Q200 certification, suitable for automotive and high-reliability applications. RCS2012F44R2CS and RC0805FR-0744R2L do not carry this certification but remain suitable for general industrial and consumer applications.

• Environmental Features: RCS2012F44R2CS includes anti-sulfur treatment in addition to moisture resistance. RC0805FR-0744R2L provides moisture resistance. CRCW080544R2FKEA and ERJ-6ENF44R2V do not specify these additional environmental treatments but maintain equivalent core performance.

• Physical Height Variation: Seated height ranges from 0.020" (0.50mm) to 0.028" (0.70mm). This variation is within typical PCB design tolerances for 0805 components and does not affect electrical substitution.

Frequently Asked Questions (FAQ)

Q: Can CRCW080544R2FKEA replace RCS2012F44R2CS in any application?

A: CRCW080544R2FKEA meets all electrical and mechanical equivalence criteria for RCS2012F44R2CS. The primary difference is the addition of Automotive AEC-Q200 certification on the Vishay Dale part, which represents enhanced qualification for automotive environments. For non-automotive applications, both parts are electrically and mechanically interchangeable.

Q: What is the significance of the height difference between substitute parts?

A: The seated height variation (0.020" to 0.028") reflects manufacturing tolerances across different suppliers. All parts conform to 0805 (2012 Metric) package specifications. PCB design accommodations for 0805 components typically allow for this range without requiring layout modifications.

Q: Are the anti-sulfur and moisture-resistant features of RCS2012F44R2CS critical for substitution?

A: These features represent enhanced environmental protection but are not required for electrical equivalence. If the application environment demands anti-sulfur treatment specifically, RCS2012F44R2CS or RC0805FR-0744R2L (moisture resistant) should be selected. For standard industrial environments, all four parts provide equivalent performance.

Q: Does AEC-Q200 certification on CRCW080544R2FKEA and ERJ-6ENF44R2V affect their use in non-automotive applications?

A: No. AEC-Q200 certification indicates additional qualification testing and reliability assurance. These parts are fully suitable for non-automotive applications and offer equivalent or superior performance compared to non-certified alternatives.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. All four parts share identical electrical specifications (44.2 Ohms ±1%, 0.125W), identical package format (0805), and identical footprint dimensions (0.079" L x 0.049" W). They are mechanically and electrically interchangeable at the PCB level.

Q: What compliance certifications apply to all substitute parts?

A: All parts are ROHS3 Compliant, REACH Unaffected, and classified as MSL 1 (Unlimited moisture sensitivity level). All carry EAR99 export classification and HTSUS code 8533.21.0030.
