Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD40106BE-NG is determined by functional equivalence across the following critical parameters:

Functional Equivalence Criteria:

• Logic type: Inverter with Schmitt trigger functionality
• Number of circuits: 6 channels
• Supply voltage range: 3V ~ 18V
• Input logic levels: Low 0.9V ~ 4V, High 3.6V ~ 10.8V
• Propagation delay: 120ns @ 15V, 50pF
• Operating temperature range: -55°C ~ 125°C
• Series classification: 4000B

The CD40106BPWR is identified as the manufacturer-recommended substitute. This part maintains identical functional specifications and electrical characteristics while differing in packaging format and product status. The substitute transitions from through-hole DIP packaging to surface-mount TSSOP packaging and from obsolete to active product status.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The CD40106BE-NG is classified as obsolete. The CD40106BPWR is the active equivalent from the same manufacturer and series, ensuring continued availability and support for new designs and production continuity.

Compliance and Certification: Both parts maintain ROHS3 compliance. The CD40106BPWR includes additional compliance documentation including REACH Unaffected status and ECCN/HTSUS classifications, providing enhanced regulatory traceability for supply chain applications.

Electrical Performance: The CD40106BPWR demonstrates improved power efficiency with reduced quiescent current (4 µA versus 20 µA) and lower output drive current (3.4mA versus 6.8mA). These reductions maintain full functional compatibility while reducing power dissipation in the circuit.

Packaging and Integration: Selection between these parts depends on board design requirements. The CD40106BE-NG uses through-hole DIP packaging suitable for breadboard prototyping and legacy PCB designs. The CD40106BPWR uses surface-mount TSSOP packaging, appropriate for modern high-density PCB layouts and automated assembly processes.

Inventory and Availability: The CD40106BPWR maintains significantly higher inventory levels (43,200 pieces) compared to the CD40106BE-NG (799 pieces), supporting volume production requirements and reducing lead time risk.

Frequently Asked Questions (FAQ)

Q: Can the CD40106BPWR directly replace the CD40106BE-NG in existing designs?

A: Electrical and functional replacement is complete. The CD40106BPWR maintains identical logic specifications, supply voltage range, input/output logic levels, and propagation delay characteristics. However, packaging differs: CD40106BE-NG uses through-hole DIP while CD40106BPWR uses surface-mount TSSOP. PCB redesign is required for physical integration.

Q: What are the advantages of the CD40106BPWR substitute?

A: The CD40106BPWR offers three primary advantages: (1) Active product status with ongoing manufacturer support versus obsolete status; (2) Improved power efficiency with 80% lower quiescent current and 50% lower output drive current; (3) Higher inventory availability supporting production volume requirements.

Q: Are there any electrical performance differences between these parts?

A: No functional differences exist. Both parts operate identically across the 3V to 18V supply range, maintain identical input logic thresholds, and deliver identical 120ns propagation delay at 15V with 50pF load. The CD40106BPWR achieves lower current consumption without compromising performance.

Q: What is the primary reason to substitute the CD40106BE-NG?

A: The CD40106BE-NG is classified as obsolete. The CD40106BPWR is the manufacturer-recommended active equivalent, ensuring component availability for new production and design continuity.

Q: Does the TSSOP package of the CD40106BPWR require different PCB layout considerations?

A: Yes. The 14-TSSOP package (0.173" width) requires surface-mount assembly capabilities and different PCB footprint design compared to the 14-DIP through-hole package (0.300" width). Trace routing and thermal management strategies may differ based on board density and application requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both the CD40106BE-NG and CD40106BPWR are ROHS3 compliant. The CD40106BPWR includes additional regulatory documentation including REACH Unaffected status.
