CD74HC192NSRG4 Equivalent & Substitute Parts

Part Overview

The CD74HC192NSRG4 is a decade counter integrated circuit manufactured by Texas Instruments, classified as a 4-bit logic counter with up/down counting capability. This component is designed for synchronous counting applications with a maximum count rate of 24 MHz and operates across a supply voltage range of 2 V to 6 V.

The CD74HC192NSRG4 is currently discontinued at DiGi Electronics, making identification of equivalent substitute parts essential for ongoing production and maintenance applications. The device remains available in limited inventory (2080 pcs), but long-term sourcing requires evaluation of active alternative components that maintain functional and electrical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74HC192NSRG4 is determined by strict equivalence across the following critical parameters:

• Logic Type: Counter, Decade (1 Element, 4 Bit)
• Electrical Characteristics: Up/Down direction, Asynchronous reset, Synchronous timing, Positive edge trigger
• Performance: 24 MHz count rate capability
• Electrical Supply: 2 V ~ 6 V operating range
• Temperature Range: -55°C ~ 125°C
• Package: 16-SOIC surface mount form factor
• Compliance: ROHS3 Compliant, MSL Level 1

The CD74HC192NSR qualifies as a parametric equivalent substitute based on identical electrical specifications, functional characteristics, and package configuration. The primary distinction is packaging format (Tape & Reel vs. standard packaging) and product status (Active vs. Discontinued).

Parameter Comparison

Engineering Selection Recommendations

The CD74HC192NSR is a direct parametric equivalent to the CD74HC192NSRG4. Both components share identical electrical specifications, functional characteristics, and physical package dimensions. The CD74HC192NSR maintains active product status with Texas Instruments, ensuring continued availability and supply chain reliability.

Selection of the CD74HC192NSR as a substitute is supported by:

• Identical logic functionality and electrical performance across all specified parameters
• Equivalent ROHS3 compliance and environmental certifications
• Matching MSL Level 1 moisture sensitivity rating
• Same 16-SOIC surface mount package configuration
• Active product status providing long-term sourcing stability

The primary consideration is packaging format: the CD74HC192NSR is supplied in Tape & Reel format, which may require adjustment to assembly and handling procedures depending on production line configuration.

Frequently Asked Questions (FAQ)

Q: Can the CD74HC192NSR be used as a direct replacement for the CD74HC192NSRG4?

A: Yes. Both components are electrically and functionally identical across all specified parameters, including logic type, count rate, voltage supply range, operating temperature, and package configuration. The primary difference is packaging format (Tape & Reel vs. standard packaging).

Q: What is the significance of the packaging format difference?

A: The CD74HC192NSRG4 uses standard packaging, while the CD74HC192NSR is supplied in Tape & Reel (TR) format. This affects handling, storage, and assembly line integration but does not impact electrical performance or functional compatibility.

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

A: No. Both components maintain identical ROHS3 compliance status, MSL Level 1 moisture sensitivity rating, and REACH unaffected status.

Q: Why is the CD74HC192NSRG4 discontinued?

A: The CD74HC192NSRG4 is discontinued at DiGi Electronics. The CD74HC192NSR remains active with Texas Instruments, providing a viable long-term sourcing alternative.

Q: What are the critical parameters that determine substitution eligibility?

A: Substitution is determined by equivalence in logic type (Counter, Decade), bit configuration (4-bit, 1 element), directional capability (Up/Down), reset type (Asynchronous), timing (Synchronous), count rate (24 MHz), trigger type (Positive Edge), supply voltage range (2 V ~ 6 V), operating temperature range (-55°C ~ 125°C), and package form factor (16-SOIC surface mount).
