Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS2012F2743CS are qualified based on the following criteria:

Electrical Parameters (Critical):

• Resistance value: 274 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Critical):

• Package type: 0805 (2012 Metric)
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Number of terminations: 2

Compliance Parameters:

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Unaffected status

All substitute parts listed meet these core parameters and are therefore electrically and mechanically interchangeable with the RCS2012F2743CS in standard circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are functionally equivalent to the RCS2012F2743CS and meet identical electrical and mechanical specifications. Selection among these alternatives may be based on:

Compliance Certifications:

• CRCW0805274KFKEA, ERJ-6ENF2743V, and RMCF0805FT274K carry AEC-Q200 automotive qualification ratings
• RC0805FR-07274KL and RCS2012F2743CS do not specify AEC-Q200 certification

Physical Height Variation:

• CRCW0805274KFKEA: 0.50mm (minimum height)
• RC0805FR-07274KL: 0.60mm
• RMCF0805FT274K: 0.65mm
• RCS2012F2743CS: 0.66mm
• ERJ-6ENF2743V: 0.70mm (maximum height)

Height differences within this range are negligible for standard PCB assembly and do not affect electrical performance. All parts maintain ROHS3 compliance and MSL Level 1 (unlimited moisture sensitivity).

Frequently Asked Questions (FAQ)

Q: Can CRCW0805274KFKEA replace RCS2012F2743CS directly on a PCB?

A: Yes. Both parts share identical electrical specifications (274 kOhms ±1%, 0.125W), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and 0805 package dimensions (2.00mm x 1.25mm). Physical height difference (0.50mm vs 0.66mm) does not affect circuit functionality or PCB assembly compatibility.

Q: What is the difference between automotive-rated and non-automotive-rated substitutes?

A: CRCW0805274KFKEA, ERJ-6ENF2743V, and RMCF0805FT274K carry AEC-Q200 automotive qualification. RCS2012F2743CS and RC0805FR-07274KL do not specify this certification. AEC-Q200 qualification indicates additional reliability testing for automotive applications. For non-automotive circuits, all parts are equivalent.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts and the main part RCS2012F2743CS are ROHS3 Compliant with MSL Level 1 (Unlimited moisture sensitivity).

Q: Does package designation 0805 (2012 Metric) apply to all listed parts?

A: Yes. All parts use the 0805 (2012 Metric) package with identical length (0.079" / 2.00mm) and width (0.049" / 1.25mm) dimensions. Height variations (0.50mm to 0.70mm) fall within standard PCB assembly tolerances.

Q: Can I use ERJ-6ENF2743V in place of RCS2012F2743CS in a high-temperature application?

A: Yes. Both parts operate across the identical temperature range (-55°C ~ 155°C) with matching temperature coefficient (±100ppm/°C). Substitution is valid for high-temperature applications.

Q: What inventory availability should I consider?

A: Inventory levels vary: ERJ-6ENF2743V (176,866 pcs), CRCW0805274KFKEA (23,482 pcs), RC0805FR-07274KL (103,627 pcs), RMCF0805FT274K (96,280 pcs), and RCS2012F2743CS (1,015 pcs). Availability should be confirmed with suppliers for production requirements.
