Substitute Part Grouping Explanation

Substitution eligibility for the AM1705BPTP4 is determined by strict equivalence across the following critical parameters:

  • Core Processor Architecture: ARM926EJ-S
  • Core Count and Bus Width: 1 Core, 32-Bit
  • Operating Frequency: 456MHz
  • Package Type: 176-HLQFP (24x24)
  • I/O Voltage Levels: 1.8V, 3.3V
  • Operating Temperature Range: 0°C ~ 90°C (TJ)
  • Mounting Configuration: Surface Mount
  • Compliance Standards: ROHS3 Compliant, REACH Unaffected

The only allowable variation between the main part and substitutes is the packaging format (Tube vs. Tray) and product status (Obsolete vs. Active), as these do not affect electrical or mechanical compatibility in the application circuit.

The AM1705DPTP4 maintains Active product status with Texas Instruments, providing improved long-term availability compared to the Obsolete AM1705BPTP4.

Selection between these parts should be based on packaging requirements and supply chain considerations. The AM1705BPTP4 is supplied in Tube packaging, while the AM1705DPTP4 is supplied in Tray packaging. Both parts meet ROHS3 compliance and REACH requirements, ensuring regulatory alignment for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can AM1705DPTP4 be used as a direct replacement for AM1705BPTP4 in existing designs?

A: Yes. The AM1705DPTP4 is electrically and mechanically identical to the AM1705BPTP4. Both parts feature the same ARM926EJ-S core, 456MHz operating frequency, 176-HLQFP package, I/O voltage levels, and interface configurations. No circuit modifications are required.

Q: What is the difference between Tube and Tray packaging?

A: Tube and Tray are packaging formats for component delivery and handling. Tube packaging is typically used for lower-volume orders, while Tray packaging is standard for higher-volume production. Both formats contain the same component with identical electrical and mechanical properties. The choice depends on assembly line requirements and order quantities.

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

A: No. Both AM1705BPTP4 and AM1705DPTP4 are ROHS3 compliant and REACH unaffected. They share identical moisture sensitivity levels (MSL 4, 72 Hours) and environmental compliance certifications.

Q: Why is the AM1705BPTP4 marked as Obsolete?

A: Obsolete status indicates that Texas Instruments has discontinued active production and support for this part number. The AM1705DPTP4, with Active status, represents the current equivalent offering and is recommended for new designs and ongoing production requirements.

Q: Are the operating temperature ranges identical?

A: Yes. Both parts operate across the same temperature range of 0°C to 90°C (TJ), ensuring thermal compatibility in equivalent application environments.
