CD4030BM XOR Logic IC Equivalent & Substitute Parts

Part Overview

The CD4030BM is a 4-channel, 2-input XOR (Exclusive OR) logic integrated circuit manufactured by Texas Instruments in the 4000B series. This part is packaged in 14-SOIC surface mount configuration and operates across a wide supply voltage range of 3V to 18V. The CD4030BM is currently discontinued at DiGi Electronics, making equivalent and substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4030BM is determined by the following critical parameters:

• Logic function: XOR (Exclusive OR) with 4 channels and 2 inputs per channel
• Supply voltage range: 3V ~ 18V minimum requirement
• Output current capability: 3.4mA minimum for both high and low states
• Propagation delay: 100ns maximum at 15V with 50pF load
• Operating temperature range: -55°C ~ 125°C
• Package compatibility: 14-SOIC surface mount form factor
• Compliance: ROHS3 and REACH requirements

Substitute parts are grouped into three categories: direct manufacturer equivalents (same part number variants), parametric equivalents (functionally identical specifications), and manufacturer-recommended alternatives (cross-manufacturer compatible parts).

Parameter Comparison

Engineering Selection Recommendations

CD4030BM96 is the primary direct substitute for CD4030BM. Both parts are manufactured by Texas Instruments with identical electrical specifications and package dimensions. The CD4030BM96 differs only in packaging format (Cut Tape & Digi-Reel versus Tube) and maintains active product status, making it the preferred choice for new procurement.

CD4070BM is a parametric equivalent offering identical electrical performance and package specifications. However, CD4070BM is also discontinued at DiGi Electronics. This part uses a different base product number (CD4070 versus CD4030) but maintains full compatibility with the original design parameters.

BU4030BF-E2 is a manufacturer-recommended alternative from Rohm Semiconductor. This part meets the core XOR logic function with 4 channels and 2 inputs. The BU4030BF-E2 operates within a narrower supply voltage range (3V ~ 16V versus 3V ~ 18V) and has a reduced operating temperature range (-40°C ~ 85°C versus -55°C ~ 125°C). The package footprint differs slightly (14-SOP 0.173" width versus 14-SOIC 0.154" width). This part maintains active product status and ROHS3 compliance.

HEF4030BT,653 is a manufacturer-recommended alternative from NXP Semiconductors. Limited parametric data is provided for this part. It maintains active product status and MSL 1 rating. Detailed electrical specifications and package information require verification against NXP datasheets before design integration.

For applications requiring the full -55°C ~ 125°C operating temperature range and 3V ~ 18V supply voltage, CD4030BM96 is the recommended substitute. For applications with relaxed temperature and voltage requirements, BU4030BF-E2 offers active availability with faster propagation delay (40ns versus 100ns).

Frequently Asked Questions (FAQ)

Q: Can CD4030BM96 be used as a direct replacement for CD4030BM?

A: Yes. CD4030BM96 is a direct substitute manufactured by Texas Instruments with identical electrical specifications, operating temperature range (-55°C ~ 125°C), supply voltage range (3V ~ 18V), and 14-SOIC package dimensions (0.154", 3.90mm width). The only difference is packaging format (Cut Tape & Digi-Reel versus Tube). Both parts are ROHS3 compliant and MSL 1 rated.

Q: What is the difference between CD4030BM and CD4070BM?

A: Both parts are XOR logic ICs with identical electrical specifications and package dimensions. The primary difference is the base product number designation (CD4030 versus CD4070). Both are discontinued at DiGi Electronics. CD4030BM96 is the preferred active substitute for either part.

Q: Can BU4030BF-E2 replace CD4030BM in all applications?

A: BU4030BF-E2 is compatible for applications operating within its specified ranges: supply voltage 3V ~ 16V (versus 3V ~ 18V for CD4030BM) and operating temperature -40°C ~ 85°C (versus -55°C ~ 125°C for CD4030BM). The package footprint differs slightly (14-SOP 0.173" width versus 14-SOIC 0.154" width), requiring PCB layout verification. BU4030BF-E2 offers faster propagation delay (40ns versus 100ns).

Q: What are the key parameters that determine substitutability?

A: Substitutability is determined by: XOR logic function with 4 channels and 2 inputs, supply voltage range compatibility, output current capability (minimum 3.4mA for both high and low states), propagation delay (100ns maximum at 15V, 50pF load), operating temperature range, 14-SOIC surface mount package compatibility, and ROHS3 compliance.

Q: Is HEF4030BT,653 a suitable substitute?

A: HEF4030BT,653 is a manufacturer-recommended alternative from NXP Semiconductors with active product status. However, limited parametric data is provided in the reference materials. Detailed electrical specifications, operating temperature range, supply voltage range, and package dimensions require verification against NXP datasheets before design integration.

Q: What is the inventory status of available substitutes?

A: CD4030BM96 has 17,687 pieces in stock (active status). BU4030BF-E2 has 5,997 pieces in stock (active status). HEF4030BT,653 has 24,175 pieces in stock (active status). CD4070BM has 1,320 pieces in stock but is discontinued at DiGi Electronics.
