Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC2012F1541CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 1.54 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters:

• 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 status
• Moisture Sensitivity Level 1
• REACH Unaffected status

All identified substitute parts meet these core requirements. Substitute parts are further categorized by composition type (Moisture Resistant Thick Film vs. Automotive AEC-Q200 Thick Film) based on feature set.

Parameter Comparison

Engineering Selection Recommendations

RC0805FR-071K54L (YAGEO) is a direct functional equivalent with identical electrical specifications and moisture-resistant thick film composition. This part maintains the same feature set as the primary component and is suitable for direct substitution in applications where the original Samsung part is unavailable.

CRCW08051K54FKEA (Vishay Dale) and ERJ-6ENF1541V (Panasonic) are functionally equivalent parts with automotive AEC-Q200 qualification. These components meet all core electrical and mechanical requirements but include additional automotive-grade reliability ratings. Selection of these parts is appropriate for applications requiring automotive-grade component qualification or when sourcing from automotive-qualified suppliers is mandated by design or procurement specifications.

All substitute parts maintain Active product status and full compliance with RoHS3 and REACH requirements. Physical height variations (0.020" to 0.028" seated height) are within typical PCB assembly tolerances for 0805 package components and do not affect functional compatibility in standard applications.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-071K54L be used as a direct replacement for RC2012F1541CS?

A: Yes. Both parts share identical electrical specifications (1.54 kOhms ±1%, 0.125W), identical package type (0805/2012 Metric), identical temperature coefficient (±100ppm/°C), identical operating temperature range (-55°C ~ 155°C), and identical compliance status (RoHS3, REACH Unaffected, MSL 1). The parts are functionally interchangeable.

Q: What is the difference between the Samsung/YAGEO parts and the Vishay/Panasonic parts?

A: The primary difference is the feature classification. RC2012F1541CS and RC0805FR-071K54L are specified as Moisture Resistant Thick Film components. CRCW08051K54FKEA and ERJ-6ENF1541V are specified as Automotive AEC-Q200 Thick Film components. All four parts meet identical core electrical and mechanical requirements. The automotive-grade parts include additional reliability qualifications suitable for automotive applications.

Q: Are there physical size differences between these parts?

A: All parts use the 0805 (2012 Metric) package with identical length (0.079") and width (0.049"). Seated height varies slightly: Samsung 0.026", YAGEO 0.024", Vishay 0.020", and Panasonic 0.028". These variations are within standard PCB assembly tolerances and do not affect board-level compatibility.

Q: Which substitute part should be selected for automotive applications?

A: CRCW08051K54FKEA (Vishay Dale) or ERJ-6ENF1541V (Panasonic) are appropriate for automotive applications due to AEC-Q200 qualification. Both parts meet automotive reliability standards while maintaining identical electrical specifications to the primary component.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. RC0805FR-071K54L, CRCW08051K54FKEA, and ERJ-6ENF1541V are all ROHS3 Compliant with REACH Unaffected status, matching the compliance profile of the RC2012F1541CS.

Q: Can these parts be used interchangeably in the same PCB design?

A: Yes. All parts conform to the 0805 (2012 Metric) package standard with identical footprint requirements. PCB layout and assembly processes do not require modification when substituting between these parts.
