Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F6493CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 649 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Moisture sensitivity level: 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant

All four substitute parts listed meet these mandatory parameters without exception. Substitute parts are grouped into two functional categories based on additional certifications: general industrial-grade resistors (RC0805FR-07649KL) and automotive-qualified resistors with AEC-Q200 certification (CRCW0805649KFKEA, ERJ-6ENF6493V, RMCF0805FT649K).

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are electrically and mechanically equivalent to the RCS2012F6493CS and are suitable for direct replacement in applications where the original part is specified. Selection among substitutes is determined by application requirements and certification needs:

For General Industrial Applications: RC0805FR-07649KL (YAGEO) provides direct equivalence without additional automotive certification overhead. This part maintains identical electrical specifications and ROHS3 compliance.

For Automotive Applications: CRCW0805649KFKEA (Vishay Dale), ERJ-6ENF6493V (Panasonic), and RMCF0805FT649K (Stackpole) are all qualified to AEC-Q200 automotive standards. These parts are suitable for automotive-grade circuit designs requiring enhanced reliability documentation and qualification testing.

For Height-Constrained PCB Layouts: CRCW0805649KFKEA offers the lowest seated height at 0.020" (0.50mm), suitable for applications with minimal vertical clearance. ERJ-6ENF6493V has the maximum seated height at 0.028" (0.70mm) and should be evaluated for space-critical designs.

All substitute parts maintain Active product status, ROHS3 compliance, and unlimited moisture sensitivity level (MSL 1), ensuring long-term availability and environmental regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805649KFKEA replace RCS2012F6493CS in non-automotive applications?

A: Yes. CRCW0805649KFKEA meets all electrical and mechanical parameters of RCS2012F6493CS. AEC-Q200 certification is an additional qualification that does not restrict use in general industrial applications. The part is fully compatible.

Q: What is the significance of the height difference between substitute parts?

A: Seated height varies between 0.020" (0.50mm) and 0.028" (0.70mm) across the substitute options. This difference is relevant only for PCB designs with height constraints or specific clearance requirements. For standard applications without height limitations, all parts are interchangeable.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. All four substitute parts are supplied in Tape & Reel (TR) packaging, matching the original RCS2012F6493CS packaging format for automated assembly compatibility.

Q: Does the anti-sulfur feature of RCS2012F6493CS affect substitution eligibility?

A: No. The anti-sulfur feature is a manufacturing characteristic of the Samsung part. All substitute parts include moisture-resistant or automotive-grade construction that provides equivalent environmental protection. Substitution is not affected by this feature difference.

Q: Which substitute part has the highest inventory availability?

A: ERJ-6ENF6493V (Panasonic) has 37,413 pieces in stock, followed by RC0805FR-07649KL (YAGEO) with 34,751 pieces. Both exceed the original part inventory of 781 pieces.

Q: Can substitute parts be mixed in the same production batch?

A: Yes. All substitute parts are electrically and mechanically identical within specified tolerances. Mixed sourcing is permissible from an engineering standpoint, though procurement and quality documentation practices should be followed per organizational standards.
