Parameter Comparison

Engineering Selection Recommendations

Product Status Alignment: Both CWR29HC106KBDB and T491C106K016AT maintain active product status, ensuring continued manufacturer support and availability.

Regulatory Compliance: Both parts share identical ECCN (EAR99) and HTSUS (8532.21.0050) classifications, confirming alignment for export control and tariff purposes. The T491C106K016AT achieves ROHS3 compliance, whereas the CWR29HC106KBDB is RoHS non-compliant. This distinction must be evaluated against specific application and regional regulatory requirements.

Moisture Sensitivity Consideration: The CWR29HC106KBDB specifies MSL 3 (168 Hours), while T491C106K016AT specifies MSL 1 (Unlimited). The substitute part demonstrates superior moisture resistance characteristics, which may provide operational advantages in humid or extended storage environments.

Packaging and Supply Chain: The CWR29HC106KBDB is supplied in bulk packaging, while T491C106K016AT is available in Cut Tape and Digi-Reel formats. Packaging selection should align with assembly process requirements and inventory management protocols.

Frequently Asked Questions (FAQ)

Q: What determines whether T491C106K016AT can substitute for CWR29HC106KBDB?

A: Substitution is based on matching component category (tantalum capacitor), regulatory classifications (ECCN and HTSUS codes), and product status (active). Both parts satisfy these criteria. Detailed electrical specifications (capacitance, voltage, tolerance) must be verified against application requirements to confirm functional compatibility.

Q: Are there differences in RoHS compliance between these parts?

A: Yes. The CWR29HC106KBDB is RoHS non-compliant, while T491C106K016AT is ROHS3 compliant. Applications subject to RoHS directives or customer specifications requiring RoHS compliance must use the KEMET part.

Q: What is the significance of the MSL rating difference?

A: CWR29HC106KBDB has MSL 3 (168 Hours), indicating moisture sensitivity requiring controlled storage and handling within 168 hours of package opening. T491C106K016AT has MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The KEMET part offers greater flexibility in storage and handling protocols.

Q: How do packaging formats affect component selection?

A: CWR29HC106KBDB is supplied in bulk packaging, suitable for manual or specialized assembly processes. T491C106K016AT is supplied in Cut Tape and Digi-Reel formats, optimized for automated pick-and-place assembly equipment. Selection depends on manufacturing process capabilities and assembly line configuration.

Q: Are export control classifications identical for both parts?

A: Yes. Both parts are classified as EAR99 under export control regulations and share the same HTSUS commodity code (8532.21.0050), confirming equivalent regulatory treatment for international trade purposes.
