CD4059AMG4 Equivalent & Substitute Parts

Part Overview

The CD4059AMG4 is a 16-bit divide-by-N counter IC manufactured by Texas Instruments, designed for digital logic applications requiring programmable frequency division. This component features asynchronous reset, positive edge triggering, and operates across a wide supply voltage range of 3V to 12V with a maximum count rate of 12 MHz.

The CD4059AMG4 is currently discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing production and maintenance applications. The primary substitute, CD4059AM, maintains identical electrical and mechanical specifications while offering active product status and improved availability.

Substitute Part Grouping Explanation

Substitution eligibility for the CD4059AMG4 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part CD4059AM qualifies as a direct equivalent based on the following criteria:

Critical Parameters for Substitution:

• Logic Type: Divide-by-N counter architecture
• Bit Configuration: 16-bit single element
• Count Rate: 12 MHz maximum
• Supply Voltage Range: 3V to 12V
• Package Type: 24-SOIC surface mount
• Reset Mechanism: Asynchronous
• Trigger Configuration: Positive edge

The CD4059AM maintains identical specifications across all electrical parameters, thermal operating range, and physical packaging. The primary distinction is product status and packaging format (tube vs. standard packaging), which does not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The CD4059AM is the recommended substitute for the discontinued CD4059AMG4. Both parts are manufactured by Texas Instruments and maintain identical electrical specifications, thermal ratings, and physical packaging dimensions. The CD4059AM offers the advantage of active product status with confirmed inventory availability (3300 pieces in stock), ensuring supply chain continuity for new designs and production requirements.

Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory standards. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints for either part, simplifying storage and handling requirements.

Frequently Asked Questions (FAQ)

Q: Can CD4059AM be used as a direct replacement for CD4059AMG4?

A: Yes. Both parts are electrically and mechanically identical. They share the same 16-bit divide-by-N counter architecture, 12 MHz count rate, 3V to 12V supply range, and 24-SOIC package configuration. The primary difference is product status; CD4059AM is currently active while CD4059AMG4 is discontinued.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the 24-SOIC (0.295", 7.50mm Width) surface mount package with identical pinout and mechanical dimensions. PCB layouts and footprints are fully compatible.

Q: What is the significance of the packaging format difference (tube vs. standard)?

A: Packaging format affects handling and storage logistics but does not impact electrical performance or functional compatibility. Tube packaging typically indicates higher volume availability and is standard for active products.

Q: Do both parts meet current compliance requirements?

A: Yes. Both CD4059AMG4 and CD4059AM are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.

Q: What is the operating temperature range for these parts?

A: Both parts operate across -55°C to 125°C, providing wide temperature range coverage for industrial and extended temperature applications.
