CD4044BPWG4 Equivalent & Substitute Parts

Part Overview

The CD4044BPWG4 is a quad NAND R/S latch logic integrated circuit manufactured by Texas Instruments, part of the 4000B series. This device functions as a 4-channel S-R latch with tri-state output capability, designed for digital logic applications requiring set-reset functionality. The CD4044BPWG4 is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity. The substitute part CD4044BPWR provides functional equivalence while maintaining active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4044BPWG4 with the CD4044BPWR is based on strict equivalence across all critical electrical and mechanical parameters. Both parts share identical specifications for logic function (S-R latch, 4-channel configuration), output characteristics (tri-state), supply voltage range (3V ~ 18V), propagation delay (50ns), output current ratings (6.8mA), operating temperature range (-55°C ~ 125°C), and physical packaging (16-TSSOP surface mount). The substitution is valid because all allowed parameters for this product category remain constant between the main part and substitute. The primary distinction is product status: CD4044BPWG4 is obsolete while CD4044BPWR maintains active status, and packaging format differs (standard vs. Cut Tape & Digi-Reel).

Parameter Comparison

Engineering Selection Recommendations

The CD4044BPWR is the direct substitute for the obsolete CD4044BPWG4. Selection of the active substitute is justified by complete electrical and mechanical equivalence across all specified parameters. Both parts maintain identical compliance certifications: ROHS3 compliance and REACH unaffected status. The CD4044BPWR offers the advantage of active product status, ensuring continued availability and manufacturing support. For applications currently using the CD4044BPWG4, transition to CD4044BPWR requires no circuit redesign or board layout modification, as pin configuration, electrical performance, and physical dimensions remain unchanged. Procurement of CD4044BPWR is recommended for new designs and replacement inventory to ensure long-term supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can CD4044BPWR directly replace CD4044BPWG4 in existing designs? A: Yes. Both parts are electrically and mechanically identical across all specified parameters. No circuit modifications or PCB layout changes are required.

Q: What is the primary reason for substitution? A: The CD4044BPWG4 is classified as obsolete. The CD4044BPWR maintains active product status, ensuring continued manufacturing support and availability.
