Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F3403CS is determined by strict alignment of the following parameters:

Electrical Parameters (Critical):

• Resistance value: 340 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters (Critical):

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

Compliance Parameters (Required):

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

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

Parameter Comparison

Engineering Selection Recommendations

All four components listed—RCS2012F3403CS, CRCW0805340KFKEA, ERJ-6ENF3403V, and RC0805FR-07340KL—are Active product status and fully compliant with ROHS3 and REACH requirements. Selection between these parts is based on availability, packaging preference, and application-specific certifications:

CRCW0805340KFKEA (Vishay Dale): Carries AEC-Q200 automotive qualification, suitable for automotive and high-reliability applications requiring automotive-grade component certification.

ERJ-6ENF3403V (Panasonic Electronic Components): Carries AEC-Q200 automotive qualification, suitable for automotive and high-reliability applications requiring automotive-grade component certification.

RC0805FR-07340KL (YAGEO): Supplied in Cut Tape (CT) & Digi-Reel® packaging format, alternative to Tape & Reel format, suitable for applications where alternative packaging is acceptable.

RCS2012F3403CS (Samsung Electro-Mechanics): Original specification with anti-sulfur and moisture-resistant features, supplied in Tape & Reel format.

All parts share identical electrical performance, operating temperature range, and compliance status. Component selection should be based on supply chain availability, packaging requirements, and whether automotive AEC-Q200 certification is mandated by application specifications.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805340KFKEA replace RCS2012F3403CS in all applications?

A: Yes. Both components share identical electrical specifications (340 kOhms ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C), package dimensions (0805 2012 Metric), and compliance certifications (ROHS3, MSL 1, REACH Unaffected). The CRCW0805340KFKEA includes AEC-Q200 automotive qualification, which provides additional certification but does not restrict use in non-automotive applications.

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

A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, suitable for automated assembly processes. Cut Tape & Digi-Reel® packaging supplies components on cut tape segments, suitable for manual assembly or lower-volume production. Both packaging formats contain identical components with identical electrical and mechanical specifications.

Q: Are the height differences between substitute parts significant?

A: Height-seated maximum dimensions range from 0.020" (0.50mm) to 0.028" (0.70mm) across the four parts. These variations are within standard 0805 package tolerances and do not affect PCB assembly, clearance, or electrical performance in standard applications. Verification is required only for applications with specific height constraints or clearance limitations.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All four parts are ROHS3 Compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and have REACH Unaffected status. The CRCW0805340KFKEA and ERJ-6ENF3403V additionally carry AEC-Q200 automotive qualification, which is a superset of standard compliance and does not restrict their use in non-automotive applications.

Q: Can I mix different manufacturers' parts in the same production batch?

A: Yes. All four parts meet identical electrical, mechanical, and compliance specifications. Mixed sourcing is permissible from an engineering standpoint. However, supply chain and quality management procedures should be reviewed to ensure traceability and consistency with procurement policies.

Q: Which substitute part should I select for new designs?

A: Selection should be based on: (1) supply chain availability and lead time, (2) packaging format preference (Tape & Reel versus Cut Tape), and (3) whether automotive AEC-Q200 certification is required. All parts are functionally equivalent and will perform identically in circuit applications.
