Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC3225F620CS are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 62 Ohms
• Tolerance: ±1%
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C to 155°C

Mechanical Parameters (Must Match):

• Package / Case: 1210 (3225 Metric)
• Composition: Thick Film
• Number of Terminations: 2

Compliance Parameters (Must Match or Exceed):

• RoHS3 Compliance: Required
• MSL Rating: 1 (Unlimited) or equivalent
• REACH Status: Unaffected

Allowable Variation:

• Power Rating: Substitute parts may have equal or higher power dissipation ratings (0.333W or greater) without affecting circuit compatibility, provided all other parameters remain constant.

The identified substitute parts AC1210FR-0762RL and RC1210FR-0762RL meet all mandatory electrical and mechanical criteria. Both substitute parts feature upgraded power ratings of 0.5W (1/2W), which provides enhanced thermal margin while maintaining identical resistance, tolerance, and package specifications.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts AC1210FR-0762RL and RC1210FR-0762RL are electrically and mechanically equivalent to the RC3225F620CS. Selection between these options is determined by application-specific requirements and supply chain considerations:

AC1210FR-0762RL Selection Criteria:

• Applications requiring automotive-grade qualification per AEC-Q200 standard
• Designs subject to automotive industry compliance requirements
• Enhanced reliability specifications for automotive environments

RC1210FR-0762RL Selection Criteria:

• General industrial and commercial applications
• Applications without automotive qualification requirements
• Standard reliability specifications for non-automotive environments

Power Rating Consideration: Both substitute parts feature 0.5W (1/2W) power ratings compared to the main part's 0.333W (1/3W) rating. This upgrade provides additional thermal margin and does not introduce compatibility issues in circuits designed for the original 0.333W specification. The substitute parts will operate at lower junction temperatures under identical load conditions.

Packaging Format: The main part is supplied in bulk packaging, while both substitute parts are supplied in Tape & Reel (TR) format. This difference affects handling, storage, and automated assembly processes but does not impact electrical or mechanical performance.

All three parts maintain identical compliance certifications: RoHS3 compliance, MSL Level 1 rating, and REACH unaffected status.

Frequently Asked Questions (FAQ)

Q: Can AC1210FR-0762RL and RC1210FR-0762RL be used interchangeably with RC3225F620CS?

A: Yes. Both substitute parts meet all mandatory electrical and mechanical specifications: 62 Ohm resistance, ±1% tolerance, 1210 (3225 Metric) package, thick film composition, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. The higher power rating (0.5W vs. 0.333W) does not prevent interchangeability and provides thermal margin.

Q: What is the difference between AC1210FR-0762RL and RC1210FR-0762RL?

A: The primary difference is automotive qualification. AC1210FR-0762RL carries AEC-Q200 automotive-grade certification, while RC1210FR-0762RL is rated for general industrial use. Both parts are electrically and mechanically identical. Selection depends on whether automotive compliance is required for the application.

Q: Does the higher power rating of substitute parts affect circuit operation?

A: No. The 0.5W (1/2W) power rating of substitute parts is a capability specification, not a requirement. Circuits designed for 0.333W operation will function identically with 0.5W-rated parts. The substitute parts will simply operate at lower junction temperatures under the same load conditions.

Q: Are the physical dimensions of substitute parts compatible with the original design?

A: Yes. All three parts use the 1210 (3225 Metric) package format. Dimensional variations are minimal: main part dimensions are 0.126" L x 0.100" W (3.20mm x 2.55mm) with 0.026" max height; substitute parts are 0.122" L x 0.102" W (3.10mm x 2.60mm) with 0.024" max height. These variations fall within standard PCB footprint tolerances and do not require design modifications.

Q: What is the difference between bulk and Tape & Reel packaging?

A: Bulk packaging is suitable for manual assembly and small-volume production. Tape & Reel (TR) packaging is optimized for automated pick-and-place assembly equipment. The electrical and mechanical properties of the components are identical; packaging format affects only handling and assembly processes.

Q: Are all three parts RoHS3 compliant?

A: Yes. RC3225F620CS, AC1210FR-0762RL, and RC1210FR-0762RL are all RoHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating and REACH unaffected status.

Q: Can substitute parts be mixed with the original part in the same production batch?

A: Yes. All three parts meet identical electrical and mechanical specifications and compliance requirements. Mixed sourcing is permissible from a technical standpoint, though procurement and quality control procedures should address traceability and documentation requirements specific to your organization.
