Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F8662CS is determined by strict alignment of the following parameters:

Critical Electrical Parameters:

• Resistance value: 86.6 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Critical Mechanical Parameters:

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

Compliance Parameters:

• RoHS3 compliance
• MSL 1 rating
• REACH Unaffected status

All four identified substitute parts meet these criteria across electrical, mechanical, and compliance dimensions. Variations in seated height (0.020" to 0.028") remain within acceptable PCB assembly tolerances for 0805 package specifications.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are classified as Active product status and maintain full ROHS3 compliance with REACH Unaffected designation, matching the regulatory posture of the RCS2012F8662CS.

CRCW080586K6FKEA (Vishay Dale): Carries AEC-Q200 automotive qualification. Lowest seated height at 0.020" provides optimal clearance for high-density PCB layouts. Inventory availability: 37,846 units.

ERJ-6ENF8662V (Panasonic Electronic Components): Carries AEC-Q200 automotive qualification. Highest seated height at 0.028" accommodates applications with less stringent height constraints. Inventory availability: 28,701 units.

RC0805FR-0786K6L (YAGEO): Moisture-resistant composition without automotive qualification. Mid-range seated height at 0.024". Highest inventory availability: 82,628 units.

RMCF0805FT86K6 (Stackpole Electronics Inc): Carries AEC-Q200 automotive qualification. Seated height at 0.026" matches the original RCS2012F8662CS specification. Inventory availability: 18,746 units.

Selection between these parts depends on application requirements: automotive-grade applications benefit from AEC-Q200 qualified options; general industrial applications accept any ROHS3 compliant variant; PCB assembly constraints may dictate seated height preferences.

Frequently Asked Questions (FAQ)

Q: Can CRCW080586K6FKEA replace RCS2012F8662CS in all applications?

A: Yes. Both parts share identical electrical specifications (86.6 kOhms ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C), identical package dimensions (0805 / 2012 Metric), and equivalent compliance certifications (ROHS3, MSL 1, REACH Unaffected). The 0.006" difference in seated height (0.020" vs 0.026") falls within standard PCB assembly tolerances for 0805 packages.

Q: What is the difference between automotive-qualified and non-automotive substitute parts?

A: CRCW080586K6FKEA, ERJ-6ENF8662V, and RMCF0805FT86K6 carry AEC-Q200 automotive qualification, indicating compliance with automotive reliability and environmental stress testing standards. RC0805FR-0786K6L does not carry this qualification. For non-automotive applications, all four parts are functionally equivalent. For automotive applications, AEC-Q200 qualified parts are preferred.

Q: Are there any dimensional constraints that would prevent substitution?

A: All substitute parts maintain the 0805 (2012 Metric) package specification with identical length (0.079") and width (0.049"). Seated heights range from 0.020" to 0.028", a 0.008" variation. Standard PCB design accommodates this range. Verify specific PCB assembly height clearance requirements if space constraints exist.

Q: Do all substitute parts have equivalent moisture resistance?

A: All parts carry MSL 1 (Unlimited) moisture sensitivity rating. The RCS2012F8662CS specifies anti-sulfur and moisture-resistant properties; RC0805FR-0786K6L explicitly lists moisture-resistant composition. CRCW080586K6FKEA, ERJ-6ENF8662V, and RMCF0805FT86K6 do not specify these features in provided data but maintain MSL 1 classification, indicating equivalent moisture handling capability.

Q: Which substitute part offers the best inventory availability?

A: RC0805FR-0786K6L (YAGEO) provides the highest inventory: 82,628 units. CRCW080586K6FKEA (Vishay Dale) offers 37,846 units. ERJ-6ENF8662V (Panasonic) provides 28,701 units. RMCF0805FT86K6 (Stackpole) has 18,746 units available.

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

A: All four substitute parts meet identical electrical and mechanical specifications. Mixing is technically permissible from a functional standpoint. However, manufacturing and quality control practices typically specify single-source components per assembly to maintain traceability and consistency in production documentation.
