Key Parameters

Substitute Part Grouping Explanation

Substitution is based strictly on exact alignment of key electrical and mechanical parameters relevant for Decade Counter ICs in the 16-TSSOP package. Matching parameters include manufacturer, series, logic type, direction, number of elements, number of bits per element, reset and timing type, count rate, trigger type, voltage supply range, operating temperature range, mounting type, and package dimensions. Compliance data (RoHS, REACH, MSL) is also matched.

Parameter Comparison

Engineering Selection Recommendations

The CD74HC192PWT is categorized as obsolete. The substitute part CD74HC192PWR, produced by the same manufacturer, maintains active product status and matches all compliance criteria, including ROHS3 compliance, MSL, and REACH status. All key mechanical and electrical parameters are equivalent, supporting direct substitution within existing designs governed by the same certifications and compliance standards.

Frequently Asked Questions (FAQ)

Q1: Which parameters must match when selecting a substitute for CD74HC192PWT?
A1: Substitution requires exact match on logic type, direction, number of elements, number of bits per element, reset type, timing, count rate, trigger type, voltage supply, operating temperature, mounting type, package/case, and all compliance/certification criteria.

Q2: Is the package of CD74HC192PWR identical to CD74HC192PWT?
A2: Both parts use the 16-TSSOP (0.173", 4.40mm Width) package and have the same supplier device package specification.

Q3: Are there differences in compliance or environmental status between these parts?
A3: Both parts are ROHS3 compliant and REACH unaffected, with Moisture Sensitivity Level 1 (Unlimited).

Q4: Can CD74HC192PWR be used as a drop-in replacement for CD74HC192PWT?
A4: All critical substitutability parameters align, enabling use within the same electrical and mechanical constraints.

Q5: Does product status affect suitability for new designs or existing designs?
A5: The CD74HC192PWT is obsolete; the CD74HC192PWR is active, which is suitable for ongoing or new production as long as all other specified parameters are consistent.
