Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS2012F1023CS are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 102 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

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

Compliance Parameters (Must Match):

• RoHS3 compliance
• Moisture sensitivity level: 1 (Unlimited)
• REACH unaffected status

All four substitute parts meet these criteria. Variations in height-seated maximum and packaging format (Tape & Reel versus Cut Tape) do not affect electrical or functional compatibility in standard PCB assembly processes.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are functionally equivalent to the RCS2012F1023CS and are suitable for direct replacement in circuit applications. Selection among these alternatives should be based on the following factors:

Automotive Applications: The CRCW0805102KFKEA (Vishay Dale), ERJ-6ENF1023V (Panasonic), and RMCF0805FT102K (Stackpole) carry AEC-Q200 automotive qualification ratings. These parts are appropriate for automotive-grade circuit designs where component reliability standards are mandated.

General Industrial Applications: The RC0805FR-07102KL (YAGEO) is suitable for general industrial and consumer applications without automotive qualification requirements. This part features moisture-resistant construction equivalent to the original Samsung component.

Packaging Format: The RCS2012F1023CS, CRCW0805102KFKEA, ERJ-6ENF1023V, and RMCF0805FT102K are supplied in Tape & Reel (TR) format. The RC0805FR-07102KL is supplied in Cut Tape (CT) & Digi-Reel® format. Packaging selection depends on assembly equipment compatibility and procurement requirements.

Inventory Availability: All parts maintain active product status with current stock levels ranging from 3,466 to 64,891 units, ensuring supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the CRCW0805102KFKEA replace the RCS2012F1023CS in a standard circuit?

A: Yes. The CRCW0805102KFKEA meets all electrical and mechanical specifications of the RCS2012F1023CS, including resistance value, tolerance, power rating, temperature coefficient, operating temperature range, package dimensions, and compliance certifications. Direct substitution is electrically and mechanically compatible.

Q: What is the difference between the substitute parts?

A: All substitute parts share identical electrical specifications (102 kOhms ±1%, 0.125W, ±100ppm/°C, -55°C ~ 155°C). Differences exist in: (1) manufacturer identity, (2) automotive qualification status (three parts carry AEC-Q200 rating; one does not), (3) height-seated maximum dimension (ranging from 0.020" to 0.028"), and (4) packaging format (Tape & Reel versus Cut Tape & Digi-Reel).

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts, including the original RCS2012F1023CS, are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Does the height variation among substitute parts affect PCB assembly?

A: Height variations (0.020" to 0.028" seated maximum) fall within standard PCB assembly tolerances for 0805 package components. These variations do not affect placement accuracy, solder reflow profiles, or final circuit performance in standard manufacturing processes.

Q: Which substitute part should I select for automotive applications?

A: For automotive applications, select from CRCW0805102KFKEA (Vishay Dale), ERJ-6ENF1023V (Panasonic), or RMCF0805FT102K (Stackpole), as these three parts carry AEC-Q200 automotive qualification ratings. The RC0805FR-07102KL does not carry this certification.

Q: Is the packaging format (Tape & Reel versus Cut Tape) important for substitution?

A: Packaging format affects procurement and assembly logistics but does not impact electrical or mechanical compatibility. Select based on your assembly equipment requirements and supply chain preferences. Tape & Reel format is standard for high-volume automated assembly; Cut Tape & Digi-Reel is suitable for lower-volume or mixed-component applications.

Q: Can I mix substitute parts within the same circuit board?

A: Yes. All substitute parts are electrically and mechanically equivalent. Mixing different manufacturers within the same circuit board does not affect circuit performance, provided all parts meet the specified electrical parameters and compliance requirements.
