Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F3094CS is determined by strict alignment of the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Resistance Value: 3.09 MOhms
• Tolerance: ±1%
• Power Rating: 0.25W (1/4W)
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C

Mechanical Parameters (Must Match Exactly):

• Package / Case: 1206 (3216 Metric)
• Number of Terminations: 2
• Composition: Thick Film

Compliance Parameters (Must Match or Exceed):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

The substitute part RC1206FR-073M09L from YAGEO satisfies all mandatory electrical and mechanical parameters. Both parts share identical resistance, tolerance, power rating, temperature coefficient, and operating temperature specifications. Both are packaged in 1206 (3216 Metric) format with two terminations and thick film composition. Compliance certifications are equivalent, with both parts meeting ROHS3 requirements and MSL Level 1 classification.

Parameter Comparison

Engineering Selection Recommendations

Both the RCS3216F3094CS and RC1206FR-073M09L are Active status products suitable for direct substitution based on electrical and mechanical equivalence. Selection between these parts should be based on:

Availability and Lead Time: The RC1206FR-073M09L (YAGEO) offers higher inventory availability with 5929 units in stock compared to 1022 units for the RCS3216F3094CS (Samsung).

Packaging Format: The RCS3216F3094CS is supplied in standard packaging, while the RC1206FR-073M09L is supplied in Tape & Reel (TR) format. Tape & Reel packaging is optimized for automated assembly processes and high-volume production environments.

Compliance Certification: Both parts maintain equivalent compliance status with ROHS3 certification and REACH Unaffected designation, ensuring regulatory requirements are satisfied in either configuration.

Environmental Features: The RCS3216F3094CS includes explicit anti-sulfur protection in addition to moisture resistance. The RC1206FR-073M09L provides moisture resistance. For applications in high-sulfur environments, the original Samsung part may offer enhanced protection; however, both parts meet MSL Level 1 requirements.

Dimensional Tolerance: Physical dimensions are within standard manufacturing tolerances for the 1206 package, with length variations of 0.1mm and height variations of 0.01mm. These differences are negligible for standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-073M09L replace RCS3216F3094CS in all applications?

A: Yes, the RC1206FR-073M09L is electrically and mechanically equivalent to the RCS3216F3094CS. Both parts share identical resistance value (3.09 MOhms), tolerance (±1%), power rating (0.25W), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and package format (1206). Compliance certifications are equivalent. The substitution is valid for standard circuit applications.

Q: What is the difference between the anti-sulfur feature on the Samsung part and the standard moisture resistance on the YAGEO part?

A: The RCS3216F3094CS includes explicit anti-sulfur protection in addition to moisture resistance, providing enhanced environmental protection in corrosive atmospheres. The RC1206FR-073M09L provides moisture resistance without specified anti-sulfur protection. For applications exposed to high-sulfur environments (such as industrial or marine settings), the Samsung part may offer superior long-term reliability. For standard indoor applications, both parts provide equivalent environmental protection.

Q: Are there packaging differences between these parts?

A: The RCS3216F3094CS is supplied in standard packaging format. The RC1206FR-073M09L is supplied in Tape & Reel (TR) format, which is optimized for automated pick-and-place assembly. Tape & Reel packaging is standard for high-volume production; standard packaging is typical for lower-volume or manual assembly processes. The actual component specifications are identical.

Q: Do the dimensional differences (0.1mm length variation, 0.01mm height variation) affect PCB compatibility?

A: No. The dimensional variations between the RCS3216F3094CS (3.20mm L x 1.60mm W x 0.66mm H) and RC1206FR-073M09L (3.10mm L x 1.60mm W x 0.65mm H) are within standard manufacturing tolerances for 1206 package components. These variations do not affect PCB footprint compatibility, solder joint formation, or assembly process parameters.

Q: Which part should be selected for new designs?

A: Selection should be based on availability, packaging requirements, and environmental specifications. The RC1206FR-073M09L offers higher inventory availability and Tape & Reel packaging suitable for automated assembly. The RCS3216F3094CS provides anti-sulfur protection for enhanced environmental resistance. Both parts are Active status and suitable for new designs.

Q: Are both parts RoHS compliant?

A: Yes, both the RCS3216F3094CS and RC1206FR-073M09L are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic component manufacturing and use.
