Parameter Comparison

Engineering Selection Recommendations

Both the WR06X8661FTL and CR168661F are Active product status components with identical electrical specifications and mechanical compatibility. Selection between these parts is based on availability and supply chain requirements rather than performance differentiation.

The CR168661F (Meritek) demonstrates a marginal height advantage of 0.002" (0.05mm) maximum seated height compared to the WR06X8661FTL, which may provide benefit in space-constrained applications. Both components maintain full ROHS3 compliance, REACH unaffected status, and EAR99 export classification.

Inventory availability should be evaluated based on project timeline and volume requirements. The WR06X8661FTL maintains 915 pieces in stock, while the CR168661F maintains 6030 pieces in stock.

Frequently Asked Questions (FAQ)

Q: Can CR168661F replace WR06X8661FTL in existing circuit designs?

A: Yes. The CR168661F meets all electrical and mechanical specifications of the WR06X8661FTL, including resistance value, tolerance, power rating, package dimensions, and operating temperature range. Direct substitution is supported without circuit modification.

Q: What is the significance of the 0.002" height difference between these parts?

A: The CR168661F maximum seated height of 0.022" (0.55mm) is 0.002" lower than the WR06X8661FTL at 0.024" (0.60mm). This difference is negligible for standard PCB assembly applications but may be relevant in applications with strict height constraints or automated placement tolerances.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both the WR06X8661FTL and CR168661F are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8533.21.0030.

Q: What does Moisture Sensitivity Level 1 indicate?

A: MSL 1 (Unlimited) indicates that both components have unlimited shelf life under normal storage conditions without requiring special moisture control measures or baking procedures prior to assembly.

Q: Are the package designations identical?

A: Yes. Both components use the 0603 (1608 Metric) package with identical length and width dimensions of 0.063" L x 0.031" W (1.60mm x 0.80mm), ensuring PCB footprint compatibility.
