Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F6813CS is determined by strict equivalence across the following parameters:

Mandatory Electrical Parameters:

• Resistance: 681 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 0.125W / 1/8W (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C to 155°C (exact match required)

Mandatory Mechanical Parameters:

• Package / Case: 0805 (2012 Metric) (exact match required)
• Number of Terminations: 2 (exact match required)
• Composition: Thick Film (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (minimum requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (minimum requirement)

All four substitute parts listed meet these mandatory criteria. Variations in packaging format (Tape & Reel vs. Cut Tape), height-seated maximum dimensions, and optional certifications (such as AEC-Q200) do not disqualify substitution but may influence selection based on application requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (RCS2012F6813CS - Samsung Electro-Mechanics): Use when Samsung supply chain is established and anti-sulfur feature is specified in design documentation. Product status is Active with full ROHS3 and REACH compliance.

Automotive Applications (CRCW0805681KFKEA, ERJ-6ENF6813V, RMCF0805FT681K): Select any of these three parts when AEC-Q200 automotive qualification is required. All three maintain identical electrical specifications and operating temperature range. CRCW0805681KFKEA offers the lowest seated height (0.50mm), ERJ-6ENF6813V provides highest inventory availability (402,200 pcs), and RMCF0805FT681K offers intermediate specifications.

General Industrial Applications (RC0805FR-07681KL - YAGEO): Use when automotive certification is not required and moisture-resistant thick film composition is sufficient. This part provides cost-effective substitution with standard inventory levels (108,096 pcs).

Packaging Consideration: RCS2012F6813CS, ERJ-6ENF6813V, RC0805FR-07681KL, and RMCF0805FT681K are supplied in Tape & Reel (TR) format. CRCW0805681KFKEA is available in Cut Tape (CT) & Digi-Reel® format. Verify packaging compatibility with assembly equipment specifications before final selection.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805681KFKEA replace RCS2012F6813CS in non-automotive applications?

A: Yes. CRCW0805681KFKEA meets all mandatory electrical and mechanical parameters. The AEC-Q200 certification is an additional qualification that does not restrict use in non-automotive circuits. The 0.50mm seated height is lower than the original part, which may be advantageous in space-constrained layouts.

Q: What is the significance of the height-seated maximum dimension variation?

A: Height-seated maximum dimensions range from 0.50mm (CRCW0805681KFKEA) to 0.70mm (ERJ-6ENF6813V). This variation affects PCB clearance and solder reflow profile. Verify that substitute parts fit within the design's height constraints, particularly in applications with tight vertical spacing or conformal coating requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All five parts listed (RCS2012F6813CS, CRCW0805681KFKEA, ERJ-6ENF6813V, RC0805FR-07681KL, RMCF0805FT681K) carry ROHS3 Compliant status and are REACH Unaffected, meeting current environmental regulations.

Q: Which substitute part has the highest inventory availability?

A: ERJ-6ENF6813V (Panasonic) offers 402,200 pcs in stock, significantly higher than other options. This part is suitable for high-volume production runs with extended lead time requirements.

Q: Can I use ERJ-6ENF6813V if the original design specifies anti-sulfur characteristics?

A: ERJ-6ENF6813V does not list anti-sulfur as a feature; it specifies AEC-Q200 automotive qualification instead. If anti-sulfur protection is a critical design requirement, use RC0805FR-07681KL (moisture resistant) or maintain the original RCS2012F6813CS. Consult design documentation to determine whether anti-sulfur is mandatory or optional.

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

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape suitable for automated pick-and-place assembly. Cut Tape (CT) & Digi-Reel® packaging provides components on cut tape segments, typically for lower-volume or manual assembly operations. Verify assembly equipment compatibility before selecting packaging format.

Q: Are all substitute parts rated for the full -55°C to 155°C operating temperature range?

A: Yes. All five parts maintain identical operating temperature specifications of -55°C to 155°C with ±100ppm/°C temperature coefficient, ensuring thermal performance equivalence across the full operating range.
