Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74F151APC is based on the following critical parameters that must remain consistent:

• Circuit configuration: 1 x 8:1 multiplexer topology
• Package format: 16-DIP through-hole package with 0.300" (7.62mm) pitch
• Voltage supply range: 4.5V ~ 5.5V single supply
• Operating temperature range: 0°C ~ 70°C
• Output current specifications: 1mA high, 20mA low (or compatible higher ratings)
• Pin-to-pin compatibility within the 74F151 base product family

The SN74F151BN from Texas Instruments meets all substitution criteria as an active product with identical package, voltage, temperature, and functional specifications.

Engineering Selection Recommendations

The SN74F151BN is the direct substitute for the obsolete 74F151APC. Selection is based on:

• Active product status ensuring long-term availability and supply chain continuity
• Identical package and pinout compatibility for direct board-level replacement
• Matching voltage supply and operating temperature specifications
• Output current specifications that meet or exceed the original part requirements (24mA low vs. 20mA)
• RoHS3 compliance providing environmental and regulatory alignment for modern manufacturing standards
• Equivalent REACH and ECCN classifications maintaining export and regulatory consistency

Frequently Asked Questions (FAQ)

Q: Can the SN74F151BN replace the 74F151APC in existing designs?

A: Yes. Both parts share identical 16-DIP package geometry, pinout, voltage supply range (4.5V ~ 5.5V), and operating temperature specifications (0°C ~ 70°C). The SN74F151BN output current rating of 24mA low exceeds the 74F151APC specification of 20mA, ensuring compatibility.

Q: What is the primary reason for substitution?

A: The 74F151APC is classified as obsolete. The SN74F151BN is an active product from Texas Instruments, providing assured supply and manufacturing continuity.

Q: Are there package or mounting differences?

A: No. Both parts use identical 16-DIP through-hole packages with 0.300" (7.62mm) pitch. Direct board-level substitution is possible without layout modifications.

Q: Do compliance certifications differ?

A: Both parts maintain REACH Unaffected status and EAR99 ECCN classification. The SN74F151BN includes RoHS3 compliance, which is standard for active products.

Q: What is the functional difference between these parts?

A: Both implement 1 x 8:1 multiplexer logic with identical circuit topology and specifications. The SN74F151BN offers higher output current capability (24mA vs. 20mA low), which is a performance enhancement rather than a limitation.
