Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for RC3216F3R0CS is determined by the following critical parameters:

Electrical Parameters: Resistance value (3 Ohms), tolerance (±1%), and power rating (0.25W) must be identical across all substitute parts.

Mechanical Parameters: Package type (1206/3216 Metric) and number of terminations (2) must match exactly to ensure PCB footprint compatibility.

Environmental Parameters: Operating temperature range (-55°C ~ 155°C) and moisture sensitivity level (MSL 1) establish the baseline environmental performance requirements.

Compliance Parameters: ROHS3 compliance is mandatory for all substitutes. REACH unaffected status applies uniformly across all identified parts.

The two substitute parts identified (RC1206FR-073RL and RMCF1206FT3R00) satisfy all mandatory electrical, mechanical, and compliance parameters. Variations in temperature coefficient, physical dimensions within tolerance, and packaging format (Tape & Reel) do not affect functional substitutability.

Parameter Comparison

Engineering Selection Recommendations

RC1206FR-073RL (YAGEO): This substitute maintains full electrical and mechanical compatibility with RC3216F3R0CS. The part carries Active product status with ROHS3 compliance and MSL 1 rating. Temperature coefficient of ±200ppm/°C provides improved thermal stability compared to the main part. Physical dimensions (3.10mm x 1.60mm) fall within acceptable tolerance for 1206 package footprints. Tape & Reel packaging is standard for high-volume production environments. Inventory availability of 53645 pieces supports consistent supply chain access.

RMCF1206FT3R00 (Stackpole Electronics Inc): This substitute provides full electrical and mechanical compatibility with additional automotive qualification through AEC-Q200 rating. The part is Active status with ROHS3 compliance and MSL 1 rating. Temperature coefficient of ±200ppm/°C matches YAGEO offering. Physical dimensions (3.20mm x 1.60mm) align with main part specifications. AEC-Q200 qualification indicates suitability for automotive applications where enhanced reliability requirements apply. Inventory availability of 15401 pieces supports production requirements.

Both substitutes are functionally equivalent for standard industrial applications. Selection between substitutes depends on supply chain preference, packaging requirements, and application-specific qualification needs.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-073RL replace RC3216F3R0CS directly on the PCB?

A: Yes. Both parts share identical electrical specifications (3 Ohms ±1%, 0.25W) and package type (1206/3216 Metric). Physical dimensions are within acceptable tolerance for the same PCB footprint. No design modifications are required.

Q: What is the difference between the temperature coefficients of these parts?

A: RC3216F3R0CS has a temperature coefficient of ±300ppm/°C, while RC1206FR-073RL and RMCF1206FT3R00 both have ±200ppm/°C. Lower temperature coefficient values indicate better resistance stability across temperature variations. This difference does not affect substitutability but may influence performance in temperature-sensitive applications.

Q: Why does RMCF1206FT3R00 have an AEC-Q200 rating?

A: AEC-Q200 is an automotive qualification standard. RMCF1206FT3R00 is qualified for automotive applications, indicating it meets enhanced reliability and testing requirements specific to the automotive industry. This qualification is optional for general industrial use but required for automotive applications.

Q: Are the physical dimensions identical across all three parts?

A: Physical dimensions are within acceptable tolerance for 1206 package classification. RC3216F3R0CS and RMCF1206FT3R00 are both 3.20mm x 1.60mm. RC1206FR-073RL is 3.10mm x 1.60mm. These variations are within standard 1206 package tolerance and do not affect PCB footprint compatibility.

Q: What does Tape & Reel (TR) packaging mean?

A: Tape & Reel is a standard packaging format for automated assembly processes. Components are wound on continuous tape with carrier tape, enabling high-speed pick-and-place machine operation. This format is standard for production environments and does not affect component performance.

Q: Are all three parts ROHS3 compliant?

A: Yes. RC3216F3R0CS, RC1206FR-073RL, and RMCF1206FT3R00 are all ROHS3 compliant. All parts are REACH unaffected and carry EAR99 ECCN classification.

Q: Which substitute should I select for high-volume production?

A: RC1206FR-073RL offers the highest inventory availability (53645 pieces) and standard industrial qualification. RMCF1206FT3R00 is appropriate if automotive qualification is required. Both support high-volume production with Tape & Reel packaging.
