Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CD74AC299M96 are determined by matching core parameters relevant to the logic shift register product category. These parameters include logic type (shift register), output type (tri-state), number of elements (1), number of bits per element (8), voltage supply range, operating temperature range, mounting type (surface mount), and compliance certifications. Equivalent substitutes must meet or exceed these specified features within their own product definitions.

Key parameters for equivalence:

• Logic Type
• Output Type
• Number of Elements
• Number of Bits per Element
• Voltage - Supply
• Operating Temperature
• Mounting Type
• Compliance Status (RoHS/REACH, MSL)

Parameter Comparison

Engineering Selection Recommendations

Both CD74AC299M96 and SN74HCS595BQBR are active status components with RoHS3 compliance and REACH unaffected status. Both are moisture sensitivity level 1 (unlimited). Based solely on product status, compliance, and provided certifications, both parts are equally suitable for applications requiring regulatory adherence and supply chain compatibility.

Frequently Asked Questions (FAQ)

Q1: What key specifications must be considered when selecting substitute shift register ICs for CD74AC299M96?
A1: Core specifications are logic type, output type, number of elements, number of bits per element, voltage supply range, operating temperature range, mounting type, and regulatory compliance status.

Q2: Do substitute parts differ in package size or pin count?
A2: Yes, substitute parts such as SN74HCS595BQBR use a 16-WQFN package compared to the original 20-SOIC package of CD74AC299M96. This must be reviewed in the context of PCB design and mechanical compatibility.

Q3: Are all substitutes RoHS compliant and suitable for unrestricted MSL applications?
A3: Both CD74AC299M96 and SN74HCS595BQBR are ROHS3 compliant and have a Moisture Sensitivity Level (MSL) of 1.

Q4: Are substitutes from the same manufacturer and series?
A4: Both products are manufactured by Texas Instruments. Series designation differs: main is 74AC, substitute is 74HCS.

Q5: Can differences in package/case affect direct replacement?
A5: Package and case differences can impact direct replacement, requiring verification of board layout compatibility before implementation.
