Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F86R6CS is determined by strict electrical and mechanical parameter matching:

Critical Matching Parameters:

• Resistance value: 86.6 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Package: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Number of terminations: 2 (exact match required)

All identified substitute parts meet these mandatory criteria. Additional features such as automotive AEC-Q200 qualification or anti-sulfur/moisture-resistant construction represent supplementary capabilities that do not disqualify substitution but may provide enhanced performance for specific applications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are functionally equivalent to the RCS2012F86R6CS based on electrical specifications, mechanical dimensions, and compliance certifications. Selection among these alternatives depends on application requirements and supply availability:

CRCW080586R6FKEA (Vishay Dale): Automotive AEC-Q200 qualified with lowest seated height (0.020" / 0.50mm). Suitable for space-constrained automotive applications and high-reliability requirements.

ERJ-6ENF86R6V (Panasonic Electronic Components): Automotive AEC-Q200 qualified. Highest seated height (0.028" / 0.70mm) among substitutes. Appropriate for automotive designs requiring Panasonic component qualification.

RC0805FR-0786R6L (YAGEO): Moisture-resistant thick film construction matching the feature set of the primary part. Mid-range seated height (0.024" / 0.60mm). Suitable for general industrial and consumer applications.

RMCF0805FT86R6 (Stackpole Electronics Inc): Automotive AEC-Q200 qualified with seated height (0.026" / 0.65mm) matching the primary part. Appropriate for automotive designs requiring Stackpole component qualification.

All parts maintain ROHS3 compliance, unlimited moisture sensitivity level (MSL 1), and identical electrical performance across the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can CRCW080586R6FKEA replace RCS2012F86R6CS in any application?

A: CRCW080586R6FKEA meets all electrical and mechanical substitution criteria. The primary difference is automotive AEC-Q200 qualification and lower seated height (0.020" vs 0.026"). Substitution is valid for applications where these characteristics are compatible with design requirements.

Q: What is the significance of seated height differences among substitute parts?

A: Seated height variations (0.020" to 0.028") reflect manufacturing tolerances across different manufacturers. For PCB assembly with tight vertical clearance constraints, verify that the substitute part's maximum seated height does not exceed available space. All parts maintain identical footprint dimensions (0.079" L x 0.049" W).

Q: Are automotive AEC-Q200 qualified parts interchangeable with non-automotive qualified parts?

A: From an electrical and mechanical standpoint, AEC-Q200 qualified parts (CRCW080586R6FKEA, ERJ-6ENF86R6V, RMCF0805FT86R6) are functionally equivalent to non-qualified parts. However, automotive applications requiring AEC-Q200 compliance must use qualified alternatives. Non-automotive applications may use any listed substitute.

Q: Do all substitute parts have identical moisture resistance?

A: All parts carry MSL 1 (Unlimited) rating. The RCS2012F86R6CS and RC0805FR-0786R6L explicitly feature moisture-resistant construction. CRCW080586R6FKEA, ERJ-6ENF86R6V, and RMCF0805FT86R6 achieve equivalent moisture performance through AEC-Q200 qualification standards.

Q: What is the impact of ±100ppm/°C temperature coefficient on circuit performance?

A: All listed parts share identical ±100ppm/°C temperature coefficient. This specification defines resistance drift across the -55°C to 155°C operating range. For a 86.6 Ohm resistor, maximum resistance change is approximately ±0.87 Ohms across the full temperature range. Substitution does not alter temperature performance characteristics.

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

A: All listed substitute parts are supplied in Tape & Reel (TR) packaging, matching the primary part's packaging format. This ensures compatibility with automated assembly processes.
