Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3216F6494CS is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Resistance value: 6.49 MOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package: 1206 (3216 Metric)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Composition: Thick Film
• Termination count: 2
• RoHS compliance: ROHS3
• Moisture sensitivity level: 1 (Unlimited)

The CRCW12066M49FKEA from Vishay Dale meets all critical electrical and mechanical parameters. Both parts share identical resistance, tolerance, power rating, package dimensions, temperature characteristics, and compliance certifications. The substitute part includes automotive AEC-Q200 qualification, which represents an additional feature not present in the main part but does not conflict with substitution.

Parameter Comparison

Engineering Selection Recommendations

RC3216F6494CS (Samsung Electro-Mechanics):

• Primary selection when moisture-resistant thick film composition is specified
• Active product status with established supply chain
• ROHS3 and REACH compliant for regulated applications
• Suitable for general industrial and consumer electronics

CRCW12066M49FKEA (Vishay Dale):

• Direct electrical and mechanical equivalent with identical core specifications
• Includes automotive AEC-Q200 qualification for enhanced reliability in automotive applications
• Active product status with higher inventory availability (10,539 pieces)
• ROHS3 and REACH compliant
• Seated height 0.024" (0.60mm) versus 0.026" (0.66mm) for main part; both acceptable for standard PCB assembly

Selection between these parts depends on application requirements and supply chain considerations. Both parts satisfy identical electrical performance, thermal characteristics, and regulatory compliance. The Vishay Dale substitute offers automotive-grade qualification when required by application specifications.

Frequently Asked Questions (FAQ)

Q: Can CRCW12066M49FKEA replace RC3216F6494CS in existing designs?

A: Yes. Both parts share identical resistance (6.49 MOhms), tolerance (±1%), power rating (0.25W), package (1206), temperature coefficient (±100ppm/°C), operating range (-55°C to 155°C), and compliance certifications (ROHS3, REACH Unaffected). Mechanical dimensions are equivalent with compatible seated heights.

Q: What is the difference in seated height between these parts?

A: RC3216F6494CS has maximum seated height of 0.026" (0.66mm). CRCW12066M49FKEA has maximum seated height of 0.024" (0.60mm). Both heights are within standard PCB assembly tolerances and do not affect interchangeability.

Q: Does the automotive AEC-Q200 rating on the Vishay part affect compatibility?

A: No. AEC-Q200 is an additional qualification that indicates enhanced reliability testing. It does not conflict with or modify the electrical or mechanical specifications. The part remains fully compatible with non-automotive applications.

Q: Are packaging formats interchangeable?

A: RC3216F6494CS is supplied in standard packaging. CRCW12066M49FKEA is available in Cut Tape (CT) and Digi-Reel® formats, or Tape & Reel (TR). Packaging format does not affect component performance; selection depends on assembly process requirements.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant and REACH unaffected. Both carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
