CD4073BM AND Gate IC 3 Channel 14-SOIC Equivalent & Substitute Parts

Part Overview

The CD4073BM is a 3-channel AND gate logic IC manufactured by Texas Instruments in the 4000B series. This part is discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing production and maintenance applications. The CD4073BM operates across a wide supply voltage range of 3V to 18V and is designed for surface mount applications in the 14-SOIC package. Equivalent parts maintain the same logic function, pin configuration, and electrical performance characteristics required for direct circuit replacement.

Substitute Part Grouping Explanation

Substitution of the CD4073BM is determined by the following critical parameters:

Logic function: 3-channel AND gate with 3 inputs per channel
Package type: 14-SOIC surface mount configuration
Supply voltage range: Minimum 3V to 18V compatibility
Input/output logic levels: Matching TTL/CMOS threshold specifications
Operating temperature range: Minimum -55°C to 125°C coverage
RoHS and compliance certifications: ROHS3 compliance required

Substitute parts are grouped by manufacturer and packaging format while maintaining electrical equivalence across these parameters. All listed substitutes preserve the core 3-channel AND gate functionality and 14-SOIC pinout required for direct circuit replacement.

Engineering Selection Recommendations

CD4073BM96 is the direct Texas Instruments equivalent available in active production status with Cut Tape and Digi-Reel packaging options. This part maintains identical electrical specifications and operating temperature range, providing the most direct replacement path.

MC14073BDR2G and MC14073BDG are onsemi equivalents with active product status. Both parts maintain the full -55°C to 125°C operating temperature range and 3V to 18V supply voltage compatibility. Output current specifications are higher at 8.8mA compared to the main part, with propagation delay of 100ns versus 90ns. These parts are suitable for applications where the increased output drive capability does not create circuit conflicts.

HEF4073BT,653 is a Nexperia USA Inc. equivalent with active product status. This part operates within a reduced supply voltage range of 3V to 15V and a narrower operating temperature range of -40°C to 85°C. The propagation delay is faster at 40ns. Selection of this part requires verification that the application does not require operation below -40°C or above 85°C, and that the 15V maximum supply voltage is compatible with the circuit design.

All substitute parts maintain ROHS3 compliance and MSL Level 1 rating, meeting the same environmental and handling requirements as the original CD4073BM.

Frequently Asked Questions (FAQ)

Q: Can CD4073BM96 be used as a direct replacement for CD4073BM?

A: Yes. CD4073BM96 is manufactured by Texas Instruments and maintains identical electrical specifications, operating temperature range, and supply voltage range. The only difference is packaging format (Cut Tape/Digi-Reel versus Tube). Pin configuration and functional performance are equivalent.

Q: What is the difference between the onsemi MC14073BDR2G and MC14073BDG parts?

A: Both are onsemi equivalents with identical electrical specifications. The primary difference is packaging: MC14073BDR2G is supplied in Tape & Reel format, while MC14073BDG is supplied in Tube format. Electrical performance and operating ranges are the same.

Q: Can HEF4073BT,653 be used in applications requiring -55°C operation?

A: No. The HEF4073BT,653 operating temperature range is -40°C to 85°C. Applications requiring operation at -55°C must use CD4073BM96, MC14073BDR2G, or MC14073BDG, which all support the full -55°C to 125°C range.

Q: Are there output current differences between substitute parts?

A: Yes. CD4073BM and CD4073BM96 specify 3.4mA output current. MC14073BDR2G and MC14073BDG specify 8.8mA output current. HEF4073BT,653 specifies 3mA output current. Verify that the application circuit can accommodate these differences in output drive capability.

Q: Do all substitute parts have the same propagation delay?

A: No. CD4073BM and CD4073BM96 specify 90ns propagation delay. MC14073BDR2G and MC14073BDG specify 100ns. HEF4073BT,653 specifies 40ns. Applications with timing-critical requirements must verify compatibility with the selected substitute part's propagation delay specification.

Q: Are all parts RoHS compliant?

A: Yes. All listed parts, including the main CD4073BM and all substitutes, are ROHS3 compliant and carry MSL Level 1 rating.
