Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74HC153DB,112 is determined by the following critical parameters:

• Functional equivalence: All substitute parts maintain the 2 x 4:1 multiplexer circuit configuration and 74HC series base product number
• Electrical compatibility: Supply voltage range (2V ~ 6V) and logic family (74HC) must match
• Package compatibility: Substitutes must accommodate the 16-pin SSOP/TSSOP surface mount footprint
• Operating temperature range: Substitutes must support the required temperature specification or exceed it
• Compliance requirements: RoHS3 compliance and REACH unaffected status must be maintained

Substitute parts are grouped by package type (SSOP vs. TSSOP) and manufacturer (Nexperia vs. Texas Instruments), with variations in output current specifications and product status noted.

Parameter Comparison

Engineering Selection Recommendations

Primary substitute (Nexperia source): 74HC153PW,118 is the direct functional equivalent from the original manufacturer. It maintains identical electrical specifications (5.2mA output current, -40°C ~ 125°C operating range) and RoHS3 compliance. The transition from 16-SSOP to 16-TSSOP packaging requires PCB footprint verification, as the TSSOP package has a narrower body width (4.40mm vs. 5.30mm).

Alternative substitutes (Texas Instruments source): SN74HC153PWR (active status) and SN74HC153PW/SN74HC153PWT (discontinued status) provide functional multiplexer operation with identical supply voltage and logic family. These parts feature higher output current capability (7.8mA vs. 5.2mA) and a reduced operating temperature range (-40°C ~ 85°C). Selection of Texas Instruments variants is appropriate when higher output drive capability is beneficial or when Nexperia sourcing is unavailable.

Compliance: All substitute parts maintain RoHS3 compliance and REACH unaffected status, meeting regulatory requirements equivalent to the original part.

Frequently Asked Questions (FAQ)

Q: Can 74HC153PW,118 directly replace 74HC153DB,112 on the PCB?

A: Functional replacement is direct; however, package geometry differs. The 74HC153PW,118 uses 16-TSSOP (4.40mm width) versus the original 16-SSOP (5.30mm width). PCB footprint compatibility must be confirmed before assembly. Both packages are 16-pin surface mount with identical pin pitch and electrical function.

Q: What is the difference between Nexperia and Texas Instruments 74HC153 variants?

A: Both manufacturers produce functionally equivalent 2 x 4:1 multiplexers within the 74HC logic family. Key differences include output current specifications (Nexperia: 5.2mA; Texas Instruments: 7.8mA) and operating temperature ranges (Nexperia: -40°C ~ 125°C; Texas Instruments: -40°C ~ 85°C). Selection depends on application current requirements and temperature environment.

Q: Are packaging options interchangeable?

A: No. SSOP and TSSOP packages have different footprints and cannot be used interchangeably without PCB redesign. SSOP (0.209" width) and TSSOP (0.173" width) require distinct land patterns. Verify your PCB design supports the selected package before procurement.

Q: Does product status affect substitution suitability?

A: Product status indicates availability and manufacturer support. Active status parts (74HC153PW,118 and SN74HC153PWR) have ongoing production and supply. Discontinued or obsolete parts may have limited availability. For new designs, active status parts are preferred; for legacy support, any electrically compatible part meeting compliance requirements is acceptable.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitute parts maintain RoHS3 compliance and REACH unaffected status, matching the regulatory profile of the original 74HC153DB,112.
