Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD4093BPW is determined by strict alignment across the following critical parameters:

Functional Parameters: Logic type (NAND Gate), circuit count (4 channels), input count (2 inputs per channel), and package configuration (14-TSSOP surface mount) must remain identical.

Electrical Parameters: Supply voltage range (3V ~ 18V), operating temperature range (-55°C ~ 125°C), and compliance certifications (ROHS3, REACH Unaffected, EAR99) must be maintained.

Mechanical Parameters: Package dimensions and mounting type must be equivalent to ensure PCB compatibility without redesign.

The identified substitutes meet these criteria while offering variations in quiescent current, output current capability, and propagation delay characteristics that may provide performance advantages depending on application requirements.

Parameter Comparison

Engineering Selection Recommendations

CD4093BPWR (Texas Instruments): This part maintains identical electrical and performance characteristics to the main part while offering active product status and superior availability (63,200 units in stock). The primary distinction is packaging format (Cut Tape & Digi-Reel versus Tube), which does not affect functional compatibility. This represents the direct equivalent for applications requiring Texas Instruments sourcing or existing supply chain alignment.

MC14093BDTR2G (onsemi): This alternative provides enhanced performance characteristics including reduced quiescent current (1 µA versus 4 µA) and faster propagation delay (80ns versus 130ns), alongside higher output current capability (8.8mA versus 3.4mA). The onsemi variant maintains full functional and mechanical compatibility while offering performance advantages for timing-critical or power-sensitive applications. Product status is active with substantial inventory availability (25,200 units).

Both substitutes maintain ROHS3 compliance, REACH unaffected status, and identical package geometry, ensuring direct PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can CD4093BPWR be used as a direct replacement for CD4093BPW?

A: Yes. Both parts are manufactured by Texas Instruments, share identical electrical specifications, and are packaged in the same 14-TSSOP configuration. The difference is packaging format (Cut Tape & Digi-Reel versus Tube), which does not affect circuit performance or PCB assembly compatibility.

Q: What are the performance differences between MC14093BDTR2G and the Texas Instruments variants?

A: The onsemi MC14093BDTR2G offers faster propagation delay (80ns versus 130ns), lower quiescent current (1 µA versus 4 µA), and higher output current capability (8.8mA versus 3.4mA). These differences may be advantageous in timing-critical or power-constrained applications but do not affect basic functional compatibility.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the 14-TSSOP package with identical pinout and functional configuration (4-channel NAND gate with 2 inputs per channel). PCB layout and schematic connections require no modification.

Q: Do all substitutes meet the same compliance requirements?

A: Yes. CD4093BPWR, MC14093BDTR2G, and the main part CD4093BPW all carry ROHS3 compliance, REACH unaffected status, and EAR99 ECCN classification. Moisture sensitivity level is 1 (Unlimited) for all variants.

Q: Which substitute should be selected for new designs?

A: CD4093BPWR is recommended for designs requiring Texas Instruments sourcing continuity. MC14093BDTR2G is recommended for applications where improved propagation delay or reduced quiescent current provides system-level benefits. Both are active products with reliable long-term availability.
