CD4028BM Equivalent & Substitute Parts

Part Overview

The CD4028BM is a 1 x 4:10 decoder logic integrated circuit manufactured by Texas Instruments in 16-SOIC surface mount packaging. This component is classified as discontinued at DiGi Electronics, making equivalent and substitute parts necessary for ongoing design requirements and production needs. The CD4028BM operates across a wide supply voltage range of 3V to 18V with output currents of 6.8mA for both high and low states, supporting single supply configurations across industrial temperature ranges from -55°C to 125°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD4028BM is determined by the following critical parameters: decoder circuit configuration (1 x 4:10), package type (16-SOIC surface mount), voltage supply range compatibility (3V ~ 18V minimum), output current capability (6.8mA minimum), operating temperature range (-55°C ~ 125°C), and compliance certifications (ROHS3, REACH Unaffected). All substitute parts listed maintain identical or superior electrical specifications within these parameters, ensuring functional equivalence in decoder applications requiring single-supply operation across extended temperature ranges.

Parameter Comparison

Engineering Selection Recommendations

CD4028BM96 is the direct Texas Instruments equivalent with identical electrical specifications and active product status, making it the primary substitute for applications requiring exact parameter matching and manufacturer continuity.

MC14028BDR2G and NLV14028BDR2G are onsemi alternatives offering enhanced output current capability (8.8mA versus 6.8mA) while maintaining full voltage supply range compatibility (3V ~ 18V) and identical operating temperature specifications. These parts are suitable for applications where increased output drive capability provides design margin.

HEF4028BT,653 from Nexperia maintains the 4000B series decoder function and 16-SOIC package but operates within a narrower voltage supply range (4.5V ~ 15.5V). This part is applicable only to designs operating within this reduced voltage window. Output current and operating temperature specifications are not provided for this part.

All substitute parts carry ROHS3 compliance and MSL 1 ratings, ensuring compatibility with standard manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can CD4028BM96 be used as a direct replacement for CD4028BM? A: Yes. CD4028BM96 is manufactured by Texas Instruments with identical decoder circuit configuration (1 x 4:10), package type (16-SOIC), voltage supply range (3V ~ 18V), output current (6.8mA), and operating temperature range (-55°C ~ 125°C). The primary difference is active product status versus discontinued status.

Q: What is the difference between the onsemi substitutes (MC14028BDR2G and NLV14028BDR2G)? A: Both onsemi parts are functionally equivalent with identical specifications. The difference lies in the base product number designation (MC14028 versus NLV14028), which reflects different product lines within onsemi's 4000B series offerings. Both provide 8.8mA output current capability.

Q: Is HEF4028BT,653 compatible with all CD4028BM applications? A: HEF4028BT,653 is compatible only with applications operating within the 4.5V ~ 15.5V supply voltage range. Applications requiring operation below 4.5V or above 15.5V require alternative substitutes. The decoder circuit configuration and 16-SOIC package are identical.

Q: Do all substitute parts support the full -55°C ~ 125°C operating temperature range? A: CD4028BM96, MC14028BDR2G, and NLV14028BDR2G support the full -55°C ~ 125°C range. HEF4028BT,653 operating temperature specifications are not provided in the available data.

Q: Are all substitute parts RoHS compliant? A: Yes. All substitute parts listed (CD4028BM96, HEF4028BT,653, MC14028BDR2G, and NLV14028BDR2G) are ROHS3 compliant with MSL 1 ratings.

Q: Which substitute offers the best output current capability? A: MC14028BDR2G and NLV14028BDR2G both provide 8.8mA output current for high and low states, compared to 6.8mA for CD4028BM and CD4028BM96. This increased capability provides additional design margin for applications with higher output loading requirements.
