CD40192BPWR Equivalent & Substitute Parts

Part Overview

The CD40192BPWR is a decade counter IC manufactured by Texas Instruments, belonging to the 4000B logic series. This device functions as a 4-bit counter with both up and down counting capability, designed for synchronous operation with positive edge triggering. The CD40192BPWR is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications. The substitute part CD40192BNSR provides functional continuity while maintaining active product status.

Substitute Part Grouping Explanation

Substitution between CD40192BPWR and CD40192BNSR is valid based on identical electrical and functional parameters. Both parts share the same base product number (CD40192) and maintain equivalent specifications across all critical operational criteria: decade counter logic type, 4-bit configuration, bidirectional counting capability, 5.5 MHz count rate, 3 V to 18 V supply voltage range, and -55°C to 125°C operating temperature. The primary distinction lies in packaging format and product status. CD40192BPWR uses 16-TSSOP packaging in tube format, while CD40192BNSR uses 16-SOIC packaging in tape and reel format. Both employ surface mount technology and maintain identical electrical performance characteristics.

Engineering Selection Recommendations

CD40192BNSR is the appropriate selection for new designs and production continuity. This part maintains active product status with Texas Instruments, ensuring long-term availability and supply chain stability. Both parts satisfy ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The CD40192BPWR, classified as obsolete, should be replaced in active applications. Selection between these parts depends on PCB layout constraints: CD40192BPWR requires 16-TSSOP footprint accommodation (4.40mm width), while CD40192BNSR requires 16-SOIC footprint accommodation (5.30mm width). Both parts deliver identical electrical performance and operational characteristics, making the substitution decision dependent on packaging compatibility with existing or planned circuit board designs.

Frequently Asked Questions (FAQ)

Q: Can CD40192BNSR directly replace CD40192BPWR in existing designs? A: Electrical substitution is valid. Both parts share identical functional specifications, supply voltage range, operating temperature range, and count rate. However, physical substitution requires PCB footprint compatibility. CD40192BPWR uses 16-TSSOP packaging while CD40192BNSR uses 16-SOIC packaging. Verify that your circuit board layout accommodates the 16-SOIC footprint (0.209" width, 5.30mm) before implementation.

Q: Why is CD40192BPWR classified as obsolete? A: Product status reflects Texas Instruments' manufacturing and support decisions. Obsolete classification indicates the part is no longer in active production. CD40192BNSR provides functional equivalence with active product status, ensuring continued availability and manufacturer support.

Q: Are there compliance differences between these parts? A: Both parts maintain identical compliance certifications: ROHS3 compliant, REACH unaffected, and MSL 1 (unlimited moisture sensitivity level). No compliance barriers exist for substitution.

Q: What is the difference between 16-TSSOP and 16-SOIC packaging? A: Both are surface mount packages with 16 pins. 16-TSSOP measures 0.173" (4.40mm) in width, while 16-SOIC measures 0.209" (5.30mm) in width. The SOIC package is slightly wider. Pin pitch and lead configuration differ between packages, requiring distinct PCB footprints.

Q: Can I use CD40192BNSR in tape and reel format for manual assembly? A: CD40192BNSR is supplied in tape and reel (TR) format, designed for automated pick-and-place assembly. Manual assembly from tape and reel is possible but not the intended application method. Verify your assembly process compatibility before procurement.

Q: Do both parts support the same supply voltage range? A: Yes. Both CD40192BPWR and CD40192BNSR operate across 3 V to 18 V supply voltage range, providing identical voltage flexibility for circuit design.
