CD74HC192PWRG4 Equivalent & Substitute Parts

Part Overview

The CD74HC192PWRG4 is a decade counter integrated circuit manufactured by Texas Instruments, classified as a 4-bit logic counter in the 74HC series. This component functions as a synchronous up/down counter with asynchronous reset capability, designed for digital counting applications requiring operation across a 2V to 6V supply voltage range.

The CD74HC192PWRG4 is currently discontinued at DiGi Electronics. Equivalent substitute parts remain available in active or alternative packaging configurations, making component sourcing feasible for new designs and production requirements.

Substitute Part Grouping Explanation

Substitute parts for the CD74HC192PWRG4 are determined by equivalence across the following critical parameters:

• Base product number: 74HC192
• Logic type and function: Decade counter, 4-bit
• Electrical specifications: 2V ~ 6V supply, 24 MHz count rate, positive edge trigger
• Package type: 16-TSSOP surface mount
• Compliance standards: ROHS3 compliant, REACH unaffected

Substitutes differ only in packaging configuration (tape & reel versus cut tape) and product status (active versus obsolete). All substitute parts maintain identical electrical and mechanical compatibility with the original part number.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring the CD74HC192PWRG4, the CD74HC192PWR is the primary substitute. This part maintains active product status with Texas Instruments and is available in higher inventory quantities (1557 pcs). The CD74HC192PWR is supplied in tape & reel packaging, standard for high-volume production environments.

The CD74HC192PWT serves as an alternative substitute, available in cut tape and Digi-Reel® packaging configurations. This part is classified as obsolete but remains in stock (1800 pcs). Selection between CD74HC192PWR and CD74HC192PWT depends on packaging requirements and procurement workflows specific to the application.

All three part numbers are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for electronic component use in regulated industries.

Frequently Asked Questions (FAQ)

Q: Are CD74HC192PWR and CD74HC192PWT electrically identical to CD74HC192PWRG4?

A: Yes. All three part numbers share identical electrical specifications, including 24 MHz count rate, 2V to 6V supply voltage range, 4-bit decade counter function, and positive edge trigger operation. Functional compatibility is complete.

Q: What is the difference between the substitute parts?

A: The primary difference is packaging configuration. CD74HC192PWR is supplied in tape & reel format, while CD74HC192PWT is supplied in cut tape and Digi-Reel® format. Product status also differs: CD74HC192PWR is active, while CD74HC192PWT is obsolete.

Q: Can I use CD74HC192PWT if CD74HC192PWR is unavailable?

A: Yes. CD74HC192PWT is a valid substitute with identical electrical and mechanical specifications. The obsolete status indicates Texas Instruments no longer manufactures this variant, but existing inventory remains available for procurement.

Q: Does the 16-TSSOP package remain consistent across all part numbers?

A: Yes. All three part numbers use the 16-TSSOP package with 0.173" width (4.40mm). PCB footprint and mounting requirements are identical, requiring no design modifications for substitution.

Q: Are there any compliance or certification differences between these parts?

A: No. All three part numbers are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity level (MSL 1, unlimited). Regulatory and environmental compliance is equivalent across all substitutes.
