Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4099BM is determined by strict equivalence across the following critical parameters:

• Logic Type and Circuit Configuration: D-Type, Addressable 1:8 topology
• Electrical Performance: 3V ~ 18V supply voltage, 50ns propagation delay, 6.8mA output current
• Package Specification: 16-SOIC surface mount form factor with identical physical dimensions
• Thermal Range: -55°C ~ 125°C operating temperature
• Compliance Standards: ROHS3 compliance and MSL Level 1 rating

The CD4099BM96 qualifies as a direct substitute based on identical electrical specifications, package geometry, and performance characteristics. The primary distinction is packaging format and product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

The CD4099BM96 is the direct functional equivalent of the CD4099BM. Both devices share identical electrical specifications, thermal performance, and package geometry. The CD4099BM96 maintains Active product status, ensuring continued availability and manufacturing support, whereas the CD4099BM is designated Last Time Buy. For new designs or ongoing procurement, the CD4099BM96 is the appropriate selection. Both parts maintain ROHS3 compliance and MSL Level 1 rating, satisfying environmental and reliability requirements. The packaging format difference (Tube versus Cut Tape & Digi-Reel) reflects distribution method only and does not affect electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can CD4099BM96 replace CD4099BM in existing designs? A: Yes. The CD4099BM96 is electrically and mechanically identical to the CD4099BM. All electrical parameters, operating temperature range, and 16-SOIC package dimensions are equivalent. Direct substitution is valid without circuit modification.

Q: What is the difference between Tube and Cut Tape packaging? A: Tube packaging (CD4099BM) and Cut Tape & Digi-Reel packaging (CD4099BM96) are distribution formats only. Both contain identical components with the same electrical and physical specifications. The packaging choice depends on procurement volume and assembly line requirements.

Q: Why is CD4099BM marked as Last Time Buy? A: Last Time Buy status indicates the manufacturer has discontinued production of this specific part number variant. The CD4099BM96, with Active status, represents the current production equivalent and is recommended for new procurement.

Q: Are there any compliance differences between these parts? A: No. Both CD4099BM and CD4099BM96 are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 rating. Compliance certifications are identical.

Q: What are the critical parameters for substitution? A: Substitution is valid when the following parameters match: Logic Type (D-Type, Addressable), Circuit Configuration (1:8), Supply Voltage (3V ~ 18V), Propagation Delay (50ns), Output Current (6.8mA), Operating Temperature (-55°C ~ 125°C), and Package Type (16-SOIC). All parameters are identical between CD4099BM and CD4099BM96.
