Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F273CS is determined by strict equivalence across the following critical parameters:

Primary Equivalence Criteria:

• Resistance value: 27 kOhms
• Tolerance: ±1%
• Package / Case: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Status: ROHS3 Compliant

Secondary Consideration:

• Power Rating: 0.125W (1/8W) for direct equivalents; 0.5W (1/2W) variants are listed as higher-rated alternatives with identical electrical characteristics but enhanced power dissipation capability

All substitute parts listed maintain identical resistance, tolerance, package dimensions, and thermal specifications. Variations in height-seated maximum and automotive certifications are noted but do not affect functional interchangeability for non-automotive applications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (0.125W, 1/8W Rating):

The following parts are functionally equivalent to RCS2012F273CS with identical power ratings:

• AC0805FR-0727KL (YAGEO) - Automotive AEC-Q200 qualified
• CRCW080527K0FKEA (Vishay Dale) - Automotive AEC-Q200 qualified
• ERJ-6ENF2702V (Panasonic) - Automotive AEC-Q200 qualified, Cut Tape packaging
• RC0805FR-0727KL (YAGEO) - Standard grade, Cut Tape packaging
• RMCF0805FT27K0 (Stackpole Electronics) - Automotive AEC-Q200 qualified

All direct equivalents maintain ROHS3 compliance, MSL Level 1, and identical electrical specifications. Selection among these parts depends on packaging format preference (Tape & Reel versus Cut Tape & Digi-Reel) and automotive certification requirements.

Higher Power Rating Alternatives (0.5W, 1/2W Rating):

The following parts provide enhanced power dissipation capability while maintaining all other electrical parameters:

• CRCW080527K0FKEAHP (Vishay Dale) - Automotive AEC-Q200, Pulse Withstanding
• ERJ-UP6F2702V (Panasonic) - Anti-Sulfur, Automotive AEC-Q200, Pulse Withstanding

These variants are suitable for applications requiring higher power handling or pulse withstanding capability without modification to circuit design.

Frequently Asked Questions (FAQ)

Q: Can AC0805FR-0727KL replace RCS2012F273CS in a standard application?

A: Yes. AC0805FR-0727KL is electrically and mechanically equivalent with identical resistance (27 kOhms), tolerance (±1%), power rating (0.125W), package (0805), and operating temperature range (-55°C ~ 155°C). The primary difference is automotive AEC-Q200 qualification, which does not prevent use in non-automotive applications.

Q: What is the difference between 0.125W and 0.5W rated parts?

A: Power rating indicates maximum continuous power dissipation capability. A 0.5W part (CRCW080527K0FKEAHP, ERJ-UP6F2702V) can dissipate four times more power than a 0.125W part while maintaining the same resistance and tolerance. Use 0.5W variants only if circuit analysis confirms power dissipation exceeds 0.125W.

Q: Does packaging format (Tape & Reel versus Cut Tape) affect electrical performance?

A: No. Packaging format affects only handling, storage, and assembly processes. Tape & Reel and Cut Tape & Digi-Reel formats contain identical components with identical electrical specifications. Selection depends on manufacturing equipment compatibility and inventory management requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH Unaffected status, matching the RCS2012F273CS environmental certification level.

Q: Can ERJ-6ENF2702V be used if the application requires anti-sulfur protection?

A: ERJ-6ENF2702V does not list anti-sulfur as a feature. For applications requiring anti-sulfur protection, select RCS2012F273CS, ERJ-UP6F2702V, or RC0805FR-0727KL. Verify application requirements before substitution.

Q: What is the significance of Temperature Coefficient ±100ppm/°C?

A: Temperature coefficient indicates resistance change per degree Celsius. All listed parts share ±100ppm/°C, meaning resistance variation remains within ±1% tolerance across the full operating temperature range (-55°C ~ 155°C). This parameter is identical across all substitutes.

Q: Is height difference between parts (0.50mm to 0.70mm) significant?

A: Height variation may affect PCB layout clearance in space-constrained designs. Verify board-level clearance requirements before selecting parts with maximum seated heights of 0.50mm (CRCW080527K0FKEA, CRCW080527K0FKEAHP) versus 0.70mm (ERJ-6ENF2702V, ERJ-UP6F2702V).
