Key Parameters

Substitute Part Grouping Explanation

The CD4059AM is a direct substitute for the CD4059AM96E4. Substitution is valid based on the following criteria:

Electrical Parameters Match:

• Identical logic type (Divide-by-N)
• Identical bit width (16 Bit)
• Identical count rate (12 MHz)
• Identical supply voltage range (3 V ~ 12 V)
• Identical operating temperature range (-55°C ~ 125°C)
• Identical reset and trigger characteristics

Mechanical Parameters Match:

• Identical package type (24-SOIC)
• Identical mounting type (Surface Mount)
• Identical physical dimensions (0.295", 7.50mm Width)

Compliance Parameters Match:

• Both ROHS3 Compliant
• Both MSL 1 (Unlimited)
• Both REACH Unaffected

The primary distinction is product status: CD4059AM96E4 is obsolete, while CD4059AM is active. The CD4059AM is available in Tube packaging with significantly higher inventory (3300 Pcs vs 993 Pcs).
