74HC253DB,118 Equivalent & Substitute Parts

Part Overview

The 74HC253DB,118 is a dual 4:1 multiplexer logic integrated circuit manufactured by Nexperia USA Inc. in a 16-SSOP surface mount package. This component functions as a data selector, routing one of four input signals to a single output based on binary control inputs. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 74HC253DB,118 is determined by the following critical parameters:

• Functional equivalence: Dual 4:1 multiplexer configuration (2 x 4:1 circuit)
• Electrical compatibility: Voltage supply range (2V ~ 6V), output current ratings (7.8mA), and logic family (74HC series)
• Thermal compatibility: Operating temperature range must meet or exceed the application requirement
• Package compatibility: Physical form factor and pin count (16-pin)
• Compliance: RoHS3 compliance and REACH unaffected status

Two substitute parts meet these criteria with variations in package type and manufacturer source.

Parameter Comparison

Engineering Selection Recommendations

74HC253D,653 (Nexperia USA Inc.)

This substitute maintains identical electrical specifications and operating temperature range (-40°C ~ 125°C) as the main part. The primary difference is the package type: 16-SOIC (0.154", 3.90mm Width) versus 16-SSOP. Both are surface mount packages with equivalent pin pitch and functionality. This part is currently in active production status with higher inventory availability (3577 Pcs). Selection of this substitute requires PCB layout modification to accommodate the SOIC package footprint.

SN74HC253DBR (Texas Instruments)

This substitute provides identical package compatibility (16-SSOP) and electrical specifications as the main part. The operating temperature range is reduced to -40°C ~ 85°C, which is suitable for applications not requiring the extended upper temperature limit of 125°C. This part is currently in active production status with substantial inventory availability (4072 Pcs). Direct PCB compatibility is maintained due to matching SSOP package specifications.

Both substitutes maintain full compliance with RoHS3 and REACH requirements. Selection between them depends on thermal requirements and package footprint constraints of the target application.

Frequently Asked Questions (FAQ)

Q: Can 74HC253D,653 replace 74HC253DB,118 directly on the PCB?

A: Electrical and functional compatibility is confirmed. However, the package differs: 74HC253D,653 uses 16-SOIC while 74HC253DB,118 uses 16-SSOP. Direct PCB replacement requires footprint modification. Pin assignments remain identical across both packages.

Q: What is the temperature limitation of SN74HC253DBR?

A: SN74HC253DBR operates from -40°C to 85°C, compared to the main part's -40°C to 125°C range. Applications requiring operation above 85°C must use 74HC253D,653 or the original part.

Q: Are all three parts RoHS3 compliant?

A: Yes. All three parts—74HC253DB,118, 74HC253D,653, and SN74HC253DBR—are ROHS3 compliant and REACH unaffected.

Q: Which substitute has better availability?

A: SN74HC253DBR (Texas Instruments) has the highest inventory at 4072 Pcs, followed by 74HC253D,653 (Nexperia) at 3577 Pcs.

Q: Do the substitutes maintain the same output current specifications?

A: Yes. All three parts provide identical output current ratings of 7.8mA for both high and low states, and operate within the same 2V ~ 6V supply voltage range.

Q: What is the primary reason to substitute the obsolete 74HC253DB,118?

A: The main part is classified as obsolete. Both substitute parts are in active production, ensuring long-term availability and supply chain continuity for new designs and production runs.
