HEF4030BT,652 XOR Logic IC - Equivalent & Substitute Parts

Part Overview

The HEF4030BT,652 is a 4-channel, 2-input XOR (Exclusive OR) logic integrated circuit manufactured by Nexperia USA Inc. in the 4000B series. This device is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. The HEF4030BT,652 operates across a supply voltage range of 3V to 15V and is housed in a 14-SOIC surface mount package with a width of 3.90mm. Finding suitable alternatives ensures design continuity and component availability for applications requiring XOR logic functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HEF4030BT,652 is determined by strict equivalence in the following parameters:

• Logic Function: All substitute parts must implement 4-channel, 2-input XOR logic
• Circuit Count & Input Configuration: 4 circuits with 2 inputs per circuit
• Supply Voltage Compatibility: Substitute parts must support the 3V to 15V range or broader
• Mounting Type: Surface mount technology required
• Package Type: 14-pin SOIC variants acceptable with compatible pinout
• Electrical Performance: Propagation delay, quiescent current, and output drive capability must meet or exceed the original specification

The following parts meet these criteria and are grouped by manufacturer and product status:

Active Status Parts: CD4030BM96 (Texas Instruments), BU4030BF-E2 (Rohm Semiconductor), CD4030BNSR (Texas Instruments)

Discontinued Status Parts: CD4030BM (Texas Instruments)

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Procurement:

CD4030BM96 is the preferred substitute. This part is manufactured by Texas Instruments, maintains active product status, and provides extended operating temperature range (-55°C to 125°C) compared to the original HEF4030BT,652. The CD4030BM96 is supplied in Cut Tape and Digi-Reel packaging with the highest inventory availability (17,687 pcs). All compliance certifications (ROHS3, REACH Unaffected, EAR99) match the original specification.

For Extended Temperature Applications:

CD4030BNSR offers the same electrical performance as CD4030BM96 with active product status and extended temperature range. This part is supplied in Tape & Reel packaging and is suitable for applications requiring temperature stability beyond the original -40°C to 85°C range.

For Reduced Output Drive Requirements:

BU4030BF-E2 (Rohm Semiconductor) provides faster propagation delay (40ns versus 55ns) and lower output high current (1.2mA versus 3mA), making it suitable for low-power applications. This part maintains active status and ROHS3 compliance. Package width is 4.40mm, which may require PCB layout verification for existing designs.

Avoid:

CD4030BM is discontinued at DiGi Electronics and should not be selected for new designs despite active status at other distributors.

Frequently Asked Questions (FAQ)

Q: Can I directly replace HEF4030BT,652 with CD4030BM96 on my PCB?

A: Yes, CD4030BM96 is a direct functional replacement. Both parts use the 14-SOIC package with 3.90mm width and identical pinout. Electrical parameters are compatible within the 3V to 15V supply range. No circuit modifications are required.

Q: What is the difference between CD4030BM96 and CD4030BNSR?

A: Both parts are manufactured by Texas Instruments and provide identical electrical performance. The primary difference is packaging: CD4030BM96 is supplied in Cut Tape and Digi-Reel format, while CD4030BNSR is supplied in Tape & Reel format. Select based on your assembly process requirements.

Q: Why does BU4030BF-E2 have a different package width (4.40mm vs 3.90mm)?

A: BU4030BF-E2 uses a 14-SOIC package with 4.40mm width, which is a wider variant of the standard SOIC package. This may affect PCB footprint compatibility. Verify your PCB design accommodates this width before selection.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (BU4030BF-E2, CD4030BM, CD4030BM96, CD4030BNSR) are ROHS3 compliant and REACH unaffected, matching the original HEF4030BT,652 compliance status.

Q: Which substitute part has the best availability?

A: CD4030BM96 has the highest inventory availability at 17,687 pcs in stock. This part is recommended for applications requiring immediate procurement and long-term supply security.

Q: Can I use these substitutes in applications operating above 15V?

A: Yes. All substitute parts support supply voltages up to 16V (BU4030BF-E2) or 18V (CD4030BM, CD4030BM96, CD4030BNSR), exceeding the original 15V maximum. Designs operating at 16V or 18V can safely use these alternatives.

Q: What is the quiescent current difference between HEF4030BT,652 and the Texas Instruments alternatives?

A: HEF4030BT,652 specifies 4 µA maximum quiescent current, while CD4030BM, CD4030BM96, and CD4030BNSR specify 1 µA maximum. The Texas Instruments parts consume less standby power, which may benefit battery-powered applications.
