BU4030BF-E2 Equivalent & Substitute Parts

Part Overview

The BU4030BF-E2 is a 4-channel XOR (Exclusive OR) logic IC manufactured by Rohm Semiconductor in a 14-SOP package. This component is currently active in production with 5997 units in stock. The BU4030BF-E2 operates across a supply voltage range of 3V to 16V and is designed for applications requiring exclusive OR logic functions in digital circuits.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design flexibility across manufacturing sources is required. Alternative XOR logic ICs from Texas Instruments and NXP Semiconductors provide functional equivalence while maintaining compatibility with the same logic family and pin configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BU4030BF-E2 is determined by the following critical parameters:

Functional Equivalence: All substitute parts must implement the same XOR logic function with 4 channels and 2 inputs per channel, ensuring pin-for-pin compatibility within the 4000B logic family.

Voltage Compatibility: The supply voltage range must encompass or overlap with the primary part's 3V to 16V specification. Substitute parts with extended voltage ranges (such as 3V to 18V) provide broader operational flexibility while maintaining compatibility.

Package Compatibility: All substitute parts must use the 14-SOIC package format to ensure mechanical and electrical compatibility with existing PCB layouts and socket configurations.

Logic Family: All parts belong to the 4000B CMOS logic series, ensuring consistent logic levels, timing characteristics, and interface compatibility.

Compliance Standards: RoHS3 compliance and MSL Level 1 rating are maintained across all substitute options, ensuring environmental and moisture handling consistency.

The CD4030BM and CD4030BM96 from Texas Instruments, along with the HEF4030BT,653 from NXP Semiconductors, meet these substitution criteria and are functionally equivalent to the BU4030BF-E2.

Engineering Selection Recommendations

CD4030BM96 (Texas Instruments) - Primary Substitute

The CD4030BM96 is the recommended primary substitute for the BU4030BF-E2. This part is currently active in production with 17687 units in stock, ensuring reliable availability. It maintains ROHS3 compliance and MSL Level 1 rating. The extended operating temperature range (-55°C to 125°C) provides broader environmental coverage compared to the primary part. The supply voltage range of 3V to 18V encompasses the BU4030BF-E2 specification. The CD4030BM96 is supplied in Cut Tape and Digi-Reel packaging, suitable for both manual and automated assembly processes.

CD4030BM (Texas Instruments) - Secondary Substitute

The CD4030BM provides functional equivalence with 2034 units currently in stock. However, this part is listed as discontinued at DiGi Electronics, which may impact long-term availability. It shares identical electrical specifications with the CD4030BM96 and maintains full ROHS3 compliance and MSL Level 1 rating. This part is supplied in Tube packaging.

HEF4030BT,653 (NXP Semiconductors) - Alternative Substitute

The HEF4030BT,653 is an active production part with 24175 units in stock, providing the highest inventory availability among all substitutes. This part maintains MSL Level 1 rating and REACH compliance. Detailed electrical parameters are not fully specified in the available data; however, as a member of the 4000B logic family, it provides functional equivalence for XOR logic applications.

Frequently Asked Questions (FAQ)

Q: Can the CD4030BM96 be used as a direct replacement for the BU4030BF-E2?

A: Yes, the CD4030BM96 is a direct functional replacement. Both parts implement 4-channel XOR logic with 2 inputs per channel in a 14-SOIC package. The CD4030BM96 operates across a supply voltage range of 3V to 18V, which encompasses the BU4030BF-E2 specification of 3V to 16V. Pin configuration and logic family compatibility are maintained.

Q: What are the differences in propagation delay between the BU4030BF-E2 and its substitutes?

A: The BU4030BF-E2 exhibits a maximum propagation delay of 40ns at 15V with a 50pF load. The CD4030BM and CD4030BM96 from Texas Instruments have a maximum propagation delay of 100ns under the same conditions. This difference may be significant in timing-critical applications where the faster response of the BU4030BF-E2 is required.

Q: Are there package size differences between the BU4030BF-E2 and substitute parts?

A: Yes, there is a minor package width difference. The BU4030BF-E2 uses a 14-SOIC package with a width of 4.40mm, while the CD4030BM and CD4030BM96 use a 14-SOIC package with a width of 3.90mm. Both are 14-SOIC packages and are mechanically compatible with standard 14-SOIC sockets and PCB layouts, though the narrower width of the Texas Instruments parts may provide slight space advantages in dense layouts.

Q: What is the quiescent current difference, and does it matter for my application?

A: The BU4030BF-E2 has a maximum quiescent current of 4 µA, while the CD4030BM and CD4030BM96 have a maximum quiescent current of 1 µA. For battery-powered or low-power applications where standby current is critical, the Texas Instruments substitutes offer superior power efficiency. For standard applications, this difference is typically negligible.

Q: Which substitute part offers the best availability?

A: The HEF4030BT,653 from NXP Semiconductors currently has the highest inventory with 24175 units in stock. The CD4030BM96 from Texas Instruments has 17687 units available and is the active production part with the most complete electrical specifications. The CD4030BM has 2034 units but is discontinued at DiGi Electronics, which may limit future availability.

Q: Are all substitute parts RoHS3 compliant?

A: The CD4030BM and CD4030BM96 from Texas Instruments are explicitly listed as ROHS3 compliant. The HEF4030BT,653 from NXP Semiconductors does not have RoHS status specified in the available data. For applications requiring verified RoHS3 compliance, the Texas Instruments parts are the confirmed options.

Q: What is the operating temperature range difference?

A: The BU4030BF-E2 operates from -40°C to 85°C. The CD4030BM and CD4030BM96 operate from -55°C to 125°C, providing extended temperature coverage at both the lower and upper limits. For applications requiring operation outside the BU4030BF-E2 temperature range, the Texas Instruments substitutes are necessary.
