BU4052BCF-E2 Equivalent & Substitute Parts

Part Overview

The BU4052BCF-E2 is a 2-circuit SP4T analog switch IC manufactured by Rohm Semiconductor, configured as a 4:1 multiplexer/demultiplexer with 160Ohm on-state resistance. The device operates across a single supply voltage range of 3V to 18V and is housed in a 16-SOP surface mount package. This part is currently in active production status with 18,148 units in stock.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design specifications allow for relaxed electrical parameters that lower component costs while maintaining functional compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the BU4052BCF-E2 is determined by the following criteria:

Mandatory Compatibility Parameters:

Switch circuit configuration must be SP4T
Multiplexer/demultiplexer circuit must be 4:1
Number of circuits must be 2
Surface mount mounting type
16-pin SOIC package family

Electrical Parameter Flexibility:

On-state resistance (Rmax) may be lower than 160Ohm (lower resistance is acceptable)
Supply voltage range must encompass or exceed the 3V minimum requirement
Operating temperature range must support -40°C minimum
Leakage current specifications may be tighter than 300nA

Packaging Variants: Substitute parts may differ in package width (3.90mm vs 4.40mm SOIC) and tape/reel configuration (Cut Tape, Tube, or Tape & Reel) without affecting electrical compatibility, provided the 16-pin SOIC footprint is maintained.

Engineering Selection Recommendations

Primary Substitutes (Active Status, Full Compatibility):

For applications operating within 2V to 6V single supply range, the CD74HC4052M96 and CD74HCT4052M96 from Texas Instruments provide direct functional equivalence with improved electrical characteristics. Both parts are in active production status. The CD74HC4052M96 supports dual supply operation (±1V ~ 5V) and offers lower on-state resistance (130Ohm) compared to the BU4052BCF-E2. The CD74HCT4052M96 is optimized for 4.5V to 5.5V supply applications.

The MC74HC4052ADR2G and MC74HC4052ADG from onsemi deliver the lowest on-state resistance (100Ohm) among available substitutes and maintain active production status. These parts support 2V to 6V single supply and ±2V to 6V dual supply operation, with superior leakage current performance (100nA).

The 74HC4052D,653 from Nexperia USA Inc. is in active production with 78,875 units in stock, offering 150Ohm on-state resistance and extended temperature range (-40°C to 125°C). This part supports both single supply (2V ~ 10V) and dual supply (±1.5V ~ 5V) configurations.

Secondary Substitutes (Last Time Buy Status):

The CD74HC4052M, CD74HC4052MT, CD74HCT4052M, and CD74HCT4052MT from Texas Instruments are designated Last Time Buy. These parts remain functionally equivalent but should be evaluated for long-term supply chain planning. All four variants feature 130Ohm on-state resistance and extended temperature range (-55°C to 125°C).

Supply Voltage Considerations:

Applications requiring operation above 10V single supply should retain the BU4052BCF-E2, as no substitute part supports the full 3V to 18V range. For applications operating within 2V to 6V, all listed substitutes are electrically compatible.

RoHS and Compliance:

All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the BU4052BCF-E2 specifications.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with lower on-state resistance than the BU4052BCF-E2?

A: Yes. Lower on-state resistance (such as 130Ohm or 100Ohm) is electrically compatible and improves signal integrity. The BU4052BCF-E2 specification of 160Ohm maximum represents the upper limit; substitutes with 150Ohm, 130Ohm, or 100Ohm are acceptable for any application designed for the original part.

Q: What is the difference between 74HC4052 and 74HCT4052 variants?

A: The 74HCT4052 series is optimized for TTL-compatible logic levels and operates within a narrower supply range (4.5V to 5.5V). The 74HC4052 series supports a wider supply range (2V to 10V). Select based on your system's supply voltage and logic interface requirements.

Q: Are the package width differences (3.90mm vs 4.40mm SOIC) significant?

A: The 16-pin SOIC footprint is standardized across all substitutes. The width difference (3.90mm vs 4.40mm) reflects different SOIC body styles but does not affect PCB layout compatibility. Both are 16-SOIC packages with identical pin pitch and electrical connections.

Q: Which substitute offers the best performance for low-leakage applications?

A: The MC74HC4052ADR2G and MC74HC4052ADG from onsemi specify 100nA maximum leakage current, compared to 300nA for the BU4052BCF-E2. These parts are suitable for applications requiring minimal off-channel leakage.

Q: Can I substitute a part with a narrower supply voltage range?

A: Only if your application operates entirely within that narrower range. For example, the 74HCT4052D,118 operates within 4.5V to 5.5V. If your design requires operation at 3V or below, this part is not suitable. Always verify that the substitute's supply range encompasses your application's operating voltage.

Q: What is the significance of "Last Time Buy" status?

A: Last Time Buy indicates the manufacturer will discontinue production after a specified date. Parts with this designation remain functionally equivalent but should not be selected for new designs requiring long-term availability. Active status parts are preferred for new applications.

Q: Are all substitutes RoHS compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 rating, matching the BU4052BCF-E2 environmental specifications.
