Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC2012F17R8CS are qualified based on the following critical parameters:

Electrical Specifications: Resistance value of 17.8 Ohms, tolerance of ±1%, and power rating of 0.125W (1/8W) must be identical across all substitutes.

Package Compatibility: All substitute parts must use the 0805 (2012 Metric) package format to ensure mechanical fit on printed circuit boards without layout modification.

Environmental Performance: Temperature coefficient of ±100ppm/°C and operating temperature range of -55°C to 155°C must be maintained.

Regulatory Compliance: ROHS3 compliance and MSL 1 rating are required for all substitutes to meet industry standards and manufacturing requirements.

Composition: Thick film construction is consistent across all qualified substitutes.

The following parts meet these substitution criteria: RC0805FR-0717R8L (YAGEO), CRCW080517R8FKEA (Vishay Dale), ERJ-6ENF17R8V (Panasonic Electronic Components), and RMCF0805FT17R8 (Stackpole Electronics Inc).

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active production status and full ROHS3 compliance, ensuring long-term availability and regulatory adherence. The RC0805FR-0717R8L (YAGEO) offers the lowest seated height at 0.024" (0.60mm), beneficial for applications with strict height constraints. The CRCW080517R8FKEA (Vishay Dale) provides automotive AEC-Q200 qualification with the most compact profile at 0.020" (0.50mm), suitable for automotive and high-reliability applications. The ERJ-6ENF17R8V (Panasonic Electronic Components) also carries AEC-Q200 qualification with the highest inventory availability at 50,369 units. The RMCF0805FT17R8 (Stackpole Electronics Inc) includes AEC-Q200 rating with seated height of 0.026" (0.65mm), matching the original part's height specification.

Selection between substitutes depends on application requirements: standard industrial applications accept any listed substitute; automotive and high-reliability applications benefit from AEC-Q200 qualified parts (CRCW080517R8FKEA, ERJ-6ENF17R8V, RMCF0805FT17R8); space-constrained designs favor lower-profile options (CRCW080517R8FKEA or RC0805FR-0717R8L); and high-volume procurement prioritizes inventory availability (ERJ-6ENF17R8V with 50,369 units in stock).

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-0717R8L replace RC2012F17R8CS directly?

A: Yes. Both parts share identical electrical specifications (17.8 Ohms ±1%, 0.125W), package format (0805), temperature coefficient (±100ppm/°C), operating range (-55°C to 155°C), and regulatory compliance (ROHS3, MSL 1). The RC0805FR-0717R8L has a slightly lower seated height (0.024" vs 0.026"), which is compatible with standard PCB layouts.

Q: What is the difference between moisture-resistant and AEC-Q200 qualified parts?

A: The RC2012F17R8CS specifies moisture-resistant thick film construction with MSL 1 rating. The substitute parts CRCW080517R8FKEA, ERJ-6ENF17R8V, and RMCF0805FT17R8 add automotive AEC-Q200 qualification, which includes additional reliability testing and performance validation for automotive environments. Both feature sets maintain MSL 1 rating and are compatible for general industrial use.

Q: Are there height differences between substitute parts?

A: Yes. Seated heights vary: RC2012F17R8CS (0.026"), RC0805FR-0717R8L (0.024"), CRCW080517R8FKEA (0.020"), ERJ-6ENF17R8V (0.028"), and RMCF0805FT17R8 (0.026"). All variations remain within the 0805 package specification and are mechanically compatible with standard PCB designs. Applications with clearance constraints should verify the specific height requirement.

Q: Which substitute has the best inventory availability?

A: ERJ-6ENF17R8V (Panasonic Electronic Components) has the highest inventory at 50,369 units in stock, followed by CRCW080517R8FKEA (Vishay Dale) at 20,524 units. For high-volume production or long-term supply assurance, these options provide superior availability.

Q: Can I use these substitutes in automotive applications?

A: The RC2012F17R8CS is suitable for general industrial applications. For automotive applications requiring AEC-Q200 qualification, use CRCW080517R8FKEA, ERJ-6ENF17R8V, or RMCF0805FT17R8, which carry explicit automotive ratings.

Q: Do all substitutes maintain the same temperature coefficient?

A: Yes. All listed substitutes maintain ±100ppm/°C temperature coefficient and -55°C to 155°C operating range, ensuring consistent thermal performance across the entire product family.
