Substitute Part Grouping Explanation

Substitution eligibility for the 7201LA12PDG is determined by the following critical parameters:

  • Memory Configuration: 4.5K (512 x 9) capacity is mandatory
  • FIFO Type: Asynchronous operation required
  • Bus Architecture: Uni-directional data flow required
  • Voltage Compatibility: 4.5V ~ 5.5V supply range
  • Package Format: 28-DIP through-hole mounting
  • Operating Temperature Range: 0°C ~ 70°C minimum support
  • Functional Features: Retransmit capability and depth/width expansion support

The SN74ACT7201LA20NP from Texas Instruments meets all substitution criteria, maintaining identical memory configuration, FIFO architecture, bus directionality, voltage specifications, and package format.

Engineering Selection Recommendations

The SN74ACT7201LA20NP is a direct functional equivalent for the 7201LA12PDG. Selection should be based on the following factors:

Product Status: The 7201LA12PDG is obsolete. The SN74ACT7201LA20NP maintains active production status, ensuring long-term availability and supply chain continuity.

Compliance and Certifications: The 7201LA12PDG carries ROHS3 compliance and REACH unaffected status. The SN74ACT7201LA20NP has not applicable RoHS status and vendor undefined REACH status. Verify compliance requirements against your application specifications and regional regulations before final selection.

Electrical Equivalence: Both devices operate within identical voltage ranges (4.5V ~ 5.5V) and temperature ranges (0°C ~ 70°C), supporting direct substitution in existing circuit designs.

Package Consideration: Both parts use 28-DIP through-hole packaging. Physical dimensions differ slightly (0.600" vs 0.300" body width), but both are compatible with standard 28-pin DIP sockets and PCB layouts designed for this package class.

Frequently Asked Questions (FAQ)

Q: Can the SN74ACT7201LA20NP replace the 7201LA12PDG in existing designs?

A: Yes. Both devices share identical memory configuration (512 x 9), asynchronous FIFO architecture, uni-directional bus structure, voltage specifications (4.5V ~ 5.5V), and operating temperature range (0°C ~ 70°C). Pin-to-pin compatibility and functional equivalence are confirmed.

Q: What is the difference in access time between these parts?

A: The 7201LA12PDG specifies 12ns access time. The SN74ACT7201LA20NP does not provide access time specification in the available data. Verify timing requirements against the Texas Instruments datasheet before implementation.

Q: Are there package dimension concerns?

A: Both parts use 28-DIP through-hole packages. The 7201LA12PDG body width is 0.600" (15.24mm), while the SN74ACT7201LA20NP is 0.300" (7.62mm). Both fit standard 28-pin DIP sockets. Verify PCB layout clearances if space constraints exist.

Q: What about compliance and certifications?

A: The 7201LA12PDG is ROHS3 compliant and REACH unaffected. The SN74ACT7201LA20NP has not applicable RoHS status and vendor undefined REACH status. Confirm compliance requirements with your quality and regulatory teams before selection.

Q: Is the SN74ACT7201LA20NP currently available?

A: Yes. The SN74ACT7201LA20NP is in active production status with 1617 units in stock, compared to the obsolete 7201LA12PDG with 976 units remaining.
