Engineering Selection Recommendations

SN74F153DR (Texas Instruments) is the primary recommended substitute for new designs and production applications. This part maintains active product status with ROHS3 compliance certification, ensuring long-term availability and regulatory alignment. The Tape & Reel packaging format supports automated assembly processes.

SN74F153D (Texas Instruments) serves as an alternative substitute with Last Time Buy status. This part is ROHS3 compliant and available in Tube packaging, suitable for lower-volume applications or manual assembly workflows.

Both Texas Instruments substitutes provide identical electrical and mechanical compatibility with the obsolete 74F153SCX while offering improved product lifecycle status and regulatory compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can SN74F153D and SN74F153DR be used interchangeably with 74F153SCX?

A: Yes. Both parts are parametric equivalents with identical circuit configuration (2 x 4:1 multiplexer), package type (16-SOIC), electrical specifications (4.5V ~ 5.5V supply, 1mA/20mA output current), and operating temperature range (0°C ~ 70°C).

Q: What is the difference between SN74F153D and SN74F153DR?

A: The primary difference is packaging format. SN74F153D is supplied in Tube packaging, while SN74F153DR is supplied in Tape & Reel format. Both parts are electrically and mechanically identical. Tape & Reel format is standard for automated pick-and-place assembly; Tube format is suitable for manual handling and lower-volume applications.

Q: Why is 74F153SCX listed as obsolete?

A: The 74F153SCX has reached end-of-life status with onsemi. Texas Instruments continues to manufacture equivalent 74F153 variants, ensuring design continuity through direct substitution.

Q: Are there any compliance differences between the substitutes?

A: Both Texas Instruments substitutes (SN74F153D and SN74F153DR) carry ROHS3 compliance certification. All three parts maintain REACH Unaffected status and MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: Which substitute should be selected for new PCB designs?

A: SN74F153DR is recommended for new designs due to active product status and Tape & Reel packaging compatibility with modern assembly equipment. SN74F153D is suitable as a secondary option if Tube packaging is preferred or if Tape & Reel availability is constrained.
