Substitute Part Grouping Explanation

Substitute parts for the RC3225F682CS are identified based on the following substitution criteria:

Mandatory Matching Parameters:

  • Resistance Value: 6.8 kOhms (exact match required)
  • Tolerance: ±1% (equal or tighter tolerance acceptable)
  • Package / Case: 1210 (3225 Metric) (physical compatibility required)
  • Composition: Thick Film (technology consistency)
  • Temperature Coefficient: ±100ppm/°C (stability specification)
  • Operating Temperature Range: -55°C ~ 155°C (environmental compatibility)
  • RoHS Status: ROHS3 Compliant (regulatory requirement)

Flexible Parameters:

  • Power Rating: Minimum 0.333W; higher ratings (0.5W, 1/2W) are acceptable as they provide additional thermal margin
  • Moisture Sensitivity Level: MSL 1 maintained across all substitutes
  • Packaging Format: May vary (bulk to Tape & Reel conversion acceptable)

The RC1210FR-076K8L from YAGEO qualifies as a substitute because it maintains all mandatory parameters while providing an upgraded power rating of 0.5W (1/2W), which exceeds the minimum requirement and enhances thermal performance in the same physical footprint.

Engineering Selection Recommendations

Primary Part: RC3225F682CS (Samsung Electro-Mechanics)

Selection criteria:

  • Active product status with established supply chain
  • ROHS3 compliant for regulatory requirements
  • MSL 1 rating provides unlimited shelf life and handling flexibility
  • 1172 pieces available in current inventory

Substitute Part: RC1210FR-076K8L (YAGEO)

Selection criteria:

  • Active product status with robust availability (7382 pieces in stock)
  • ROHS3 compliant; meets all regulatory requirements
  • MSL 1 rating maintains handling and storage compatibility
  • Upgraded power rating (0.5W vs. 0.333W) provides enhanced thermal margin without footprint change
  • Tape & Reel packaging suitable for automated assembly processes
  • Dimensional compatibility within 1210 package specification tolerances

Both parts satisfy all mandatory electrical and mechanical parameters. The YAGEO substitute offers superior thermal performance through increased power rating while maintaining identical electrical characteristics and package footprint. Selection between these parts should be based on supply availability, packaging requirements (bulk vs. Tape & Reel), and preferred supplier qualification status.

Frequently Asked Questions (FAQ)

Q: Can RC1210FR-076K8L replace RC3225F682CS in all applications?

A: Yes. The substitute part maintains identical resistance value (6.8 kOhms), tolerance (±1%), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). The increased power rating (0.5W vs. 0.333W) is a non-limiting upgrade that enhances thermal performance. Both parts use thick film composition and are housed in the 1210 (3225 Metric) package with compatible physical dimensions.

Q: What is the difference in physical size between these parts?

A: RC3225F682CS measures 0.126" L x 0.100" W (3.20mm x 2.55mm) with maximum seated height of 0.026" (0.66mm). RC1210FR-076K8L measures 0.122" L x 0.102" W (3.10mm x 2.60mm) with maximum seated height of 0.024" (0.60mm). Both dimensions fall within the 1210 package specification tolerance and are PCB footprint compatible.

Q: Are there packaging format differences?

A: RC3225F682CS is supplied in standard packaging format. RC1210FR-076K8L is supplied in Tape & Reel (TR) format, which is optimized for automated assembly processes. Both formats contain identical electrical components; packaging selection depends on assembly methodology and handling requirements.

Q: Do both parts meet the same compliance standards?

A: Yes. Both RC3225F682CS and RC1210FR-076K8L are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8533.21.0030. Both maintain MSL 1 (Unlimited) moisture sensitivity level, providing identical handling and storage flexibility.

Q: What is the temperature coefficient significance?

A: Both parts specify ±100ppm/°C temperature coefficient, which defines the resistance value change per degree Celsius across the operating range. This specification is identical between the main part and substitute, ensuring equivalent stability and predictability across the -55°C to 155°C operating temperature range.

Q: Can the substitute part be used in high-temperature applications?

A: Yes. RC1210FR-076K8L maintains the same maximum operating temperature of 155°C as the original RC3225F682CS. The upgraded power rating (0.5W) actually provides better thermal performance margin in high-temperature environments.

Q: Is tolerance specification critical for substitution?

A: Yes. Both parts maintain ±1% tolerance, which is the precision class requirement. This tolerance specification ensures that the actual resistance value remains within acceptable limits for circuit design calculations. Substitutes with equal or tighter tolerance are acceptable; looser tolerance substitutes are not compatible.
