SN74S1053PW Equivalent & Substitute Parts

Part Overview

The SN74S1053PW is a 16-bit Schottky Barrier Diode Bus-Termination Array IC manufactured by Texas Instruments in a 20-TSSOP surface mount package. This component is classified as Last Time Buy, indicating discontinued production status. The part operates across a temperature range of 0°C to 70°C and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Due to Last Time Buy status, identifying equivalent substitute parts with compatible electrical and mechanical specifications is essential for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SN74S1053PW is determined by the following critical parameters:

• Logic Type: Must be Schottky Barrier Diode Bus-Termination Array
• Number of Bits: Must be 16-bit configuration
• Package / Case: Must be 20-TSSOP (0.173", 4.40mm Width)
• Mounting Type: Must be Surface Mount
• Operating Temperature Range: Must support 0°C ~ 70°C minimum
• Base Product Number: Must be 74S1053 series

The SN74S1053PWR qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility across all critical parameters. The primary distinction is packaging format: the main part is supplied in Tube packaging, while the substitute is supplied in Tape & Reel (TR) format. Both variants share the same 20-TSSOP package footprint and are functionally equivalent.

Parameter Comparison

Engineering Selection Recommendations

The SN74S1053PWR is a qualified substitute for the SN74S1053PW based on identical electrical and mechanical specifications. Both parts are manufactured by Texas Instruments, share the same 74S1053 base product number, and are housed in the 20-TSSOP package with matching pin configurations and functional characteristics.

The SN74S1053PWR maintains Active product status, providing continued availability and manufacturing support compared to the Last Time Buy status of the original part. Both variants meet ROHS3 compliance requirements and carry identical moisture sensitivity ratings.

The substitution is valid for applications requiring 16-bit Schottky Barrier Diode Bus-Termination Array functionality within the 0°C to 70°C operating temperature range. The primary consideration is packaging format: Tube versus Tape & Reel. Selection between these formats depends on assembly process requirements and procurement volume specifications.

Frequently Asked Questions (FAQ)

Q: Can SN74S1053PWR be used as a direct replacement for SN74S1053PW?

A: Yes. Both parts are electrically and mechanically identical. They share the same 20-TSSOP package footprint, pin configuration, and functional specifications. The difference is packaging format only: Tube versus Tape & Reel.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging is used for manual handling and smaller volume orders. Tape & Reel packaging is designed for automated assembly processes and higher volume production. Both formats contain the same component with identical electrical performance.

Q: Why is the original part marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has discontinued production. The SN74S1053PWR, with Active status, represents the current production equivalent and is recommended for new designs and ongoing procurement.

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

A: No. Both parts operate across 0°C to 70°C and maintain identical ROHS3 compliance and moisture sensitivity ratings (MSL 1).

Q: Can I mix Tube and Tape & Reel packaging in the same assembly?

A: Yes, provided your assembly process can accommodate both packaging formats. However, standardizing on a single format (typically Tape & Reel for production) is recommended for process consistency.
