Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F9310CS is determined by strict equivalence across the following parameters:

Electrical Specifications: Resistance value (931 Ohms), tolerance (±1%), and power rating (0.125W) must be identical. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance boundaries.

Mechanical Compatibility: Package designation (0805 / 2012 Metric) and composition (Thick Film) are mandatory. Physical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) and termination count (2) must match.

Compliance & Environmental: RoHS3 compliance, MSL rating (1), and REACH unaffected status are required. Packaging format (Tape & Reel) ensures supply chain compatibility.

Functional Features: Anti-sulfur and moisture-resistant characteristics, or equivalent automotive-grade certifications (AEC-Q200), are acceptable alternatives that maintain or exceed environmental protection.

All identified substitute parts meet these criteria without exception.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts are Active status components with ROHS3 compliance and unlimited MSL ratings, confirming long-term availability and environmental regulatory alignment.

For general-purpose applications: RC0805FR-07931RL (YAGEO) and RCS2012F9310CS (Samsung) are functionally equivalent, both featuring moisture-resistant thick film construction without automotive certification requirements.

For automotive or high-reliability applications: CRCW0805931RFKEA (Vishay Dale), ERJ-6ENF9310V (Panasonic), and RMCF0805FT931R (Stackpole) carry AEC-Q200 certification, indicating qualification for automotive-grade performance and environmental stress testing.

For space-constrained PCB layouts: CRCW0805931RFKEA exhibits the lowest seated height (0.020" / 0.50mm), providing clearance advantages in densely populated assemblies.

For standard applications with no height constraints: All substitute parts are mechanically compatible within the 0805 package envelope, with seated heights ranging from 0.020" to 0.028".

Frequently Asked Questions (FAQ)

Q: Can RCS2012F9310CS be directly replaced with CRCW0805931RFKEA?

A: Yes. Both components share identical electrical specifications (931 Ohms ±1%, 0.125W), operate across -55°C to 155°C, and are packaged in 0805 (2012 Metric) format. CRCW0805931RFKEA includes AEC-Q200 automotive certification, which does not restrict use in general-purpose applications. Seated height difference (0.020" vs 0.026") is within typical PCB assembly tolerances.

Q: What is the difference between anti-sulfur/moisture-resistant and AEC-Q200 rated parts?

A: Anti-sulfur and moisture-resistant features address environmental degradation in corrosive or humid conditions. AEC-Q200 certification indicates the component has undergone automotive-grade qualification testing, including thermal cycling, humidity bias, and mechanical stress. AEC-Q200 parts inherently include moisture and environmental protection. Both feature sets are compatible with the RCS2012F9310CS application space.

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

A: Yes. All identified substitute parts are supplied in Tape & Reel (TR) format, ensuring compatibility with automated pick-and-place assembly equipment and standard component handling procedures.

Q: Does seated height variation affect PCB assembly?

A: Seated height variations (0.020" to 0.028") are within standard PCB assembly tolerances and do not affect reflow soldering, wave soldering, or component placement accuracy. Height differences become relevant only in applications with strict vertical clearance constraints (e.g., confined enclosures or stacked PCB assemblies).

Q: Can these parts be used interchangeably in the same circuit design?

A: Yes. All substitute parts meet identical electrical and mechanical specifications. Interchangeability is confirmed across resistance value, tolerance, power rating, temperature coefficient, operating temperature range, package dimensions, and compliance certifications. No circuit redesign or validation is required for substitution.

Q: Which substitute part offers the best inventory availability?

A: ERJ-6ENF9310V (Panasonic) shows the highest inventory level at 48,144 pieces. CRCW0805931RFKEA (Vishay Dale) provides 2,590 pieces, and RMCF0805FT931R (Stackpole) offers 5,509 pieces. Inventory levels are subject to change and should be verified with current supplier data.
