Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F1403CS is determined by the following critical parameters:

Electrical Specifications: Resistance value (140 kOhms), tolerance (±1%), and power rating (0.125W) must match exactly. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance boundaries.

Mechanical Compatibility: Package type (0805 / 2012 Metric) and number of terminations (2) must be identical to ensure PCB footprint compatibility and soldering process alignment.

Environmental & Compliance Requirements: RoHS3 compliance and Moisture Sensitivity Level 1 (Unlimited) are mandatory for equivalent substitution. REACH status and ECCN classification must remain consistent.

Composition & Construction: Thick film composition ensures consistent electrical behavior and thermal characteristics across substitute parts.

All identified substitute parts meet these criteria and are classified as direct functional equivalents.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are Active product status components with ROHS3 compliance and REACH Unaffected classification, meeting regulatory requirements for industrial and commercial applications.

CRCW0805140KFKEA (Vishay Dale): Automotive AEC-Q200 rated. Lowest seated height (0.50mm) provides optimal clearance for high-density PCB layouts. Highest inventory availability (19,460 pcs).

ERJ-6ENF1403V (Panasonic Electronic Components): Automotive AEC-Q200 rated. Highest inventory availability (91,759 pcs) ensures supply chain continuity. Seated height 0.70mm suitable for standard PCB designs.

KTR10EZPF1403 (Rohm Semiconductor): Automotive AEC-Q200 rated with High Voltage feature designation. Seated height 0.65mm. Suitable for applications requiring enhanced voltage performance characteristics.

RC0805FR-07140KL (YAGEO): Moisture Resistant feature matches original part specification. Cut Tape and Digi-Reel packaging option. Seated height 0.60mm provides balanced clearance profile.

Selection among these equivalents depends on supply availability, packaging format preference (Tape & Reel vs. Cut Tape), and specific application requirements for automotive qualification or high-voltage performance.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805140KFKEA replace RCS2012F1403CS directly on the PCB?

A: Yes. Both components share identical electrical specifications (140 kOhms ±1%, 0.125W), package type (0805), and environmental ratings (RoHS3, MSL 1). The 0.50mm seated height of CRCW0805140KFKEA is lower than the original 0.66mm, providing additional PCB clearance without affecting functionality.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging is supplied on continuous carrier tape for automated pick-and-place assembly. Cut Tape and Digi-Reel packaging provides smaller quantities on cut tape segments, suitable for manual assembly or lower-volume production. Both formats contain identical components with matching electrical and mechanical specifications.

Q: Are all substitute parts automotive-qualified?

A: CRCW0805140KFKEA, ERJ-6ENF1403V, and KTR10EZPF1403 carry AEC-Q200 automotive qualification. RCS2012F1403CS and RC0805FR-07140KL do not list automotive ratings but maintain equivalent electrical performance and environmental compliance for general industrial applications.

Q: Does seated height variation affect circuit performance?

A: Seated height differences (0.50mm to 0.70mm range) do not affect electrical performance. Variation impacts PCB layout clearance and solder joint geometry. Components with lower seated heights provide additional clearance for dense PCB designs or components mounted on reverse side.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. All substitute parts operate across the identical temperature range (-55°C ~ 155°C) with matching temperature coefficient (±100ppm/°C), ensuring consistent resistance stability across thermal extremes.

Q: What does AEC-Q200 qualification indicate?

A: AEC-Q200 is an automotive industry standard qualification for passive components. It certifies that components meet stringent reliability, performance, and environmental stress testing requirements for automotive applications. Non-AEC-Q200 parts remain suitable for industrial and consumer applications.
