CD4007UBM Equivalent & Substitute Parts

Part Overview

The CD4007UBM is a Complementary Pair Plus Inverter logic IC manufactured by Texas Instruments in the 4000B series. This device integrates dual complementary transistor pairs with an inverter function in a 14-SOIC surface mount package. The CD4007UBM is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. Substitute parts maintain functional equivalence through identical logic type, electrical specifications, and mechanical compatibility while offering active product status from alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4007UBM is determined by strict equivalence across the following critical parameters:

Functional Equivalence: All substitute parts maintain the Complementary Pair Plus Inverter logic type, ensuring identical circuit behavior and pin configuration.

Electrical Specifications: Supply voltage range (3V ~ 18V), number of bits (3), and operating temperature range (-55°C ~ 125°C) are identical across all qualified substitutes, guaranteeing direct functional replacement without circuit redesign.

Mechanical Compatibility: All substitute parts use the 14-SOIC (0.154", 3.90mm Width) package with surface mount technology, enabling direct PCB footprint compatibility.

Regulatory Compliance: All substitutes maintain ROHS3 compliance, REACH unaffected status, and MSL 1 rating, satisfying environmental and reliability requirements.

Packaging Variants: Substitutes are available in Tube and Tape & Reel (TR) packaging formats. Selection depends on assembly process requirements rather than functional capability.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: CD4007UBM96 (Texas Instruments) provides direct manufacturer continuity with active product status. This part maintains the original design lineage while offering improved availability and supply chain stability compared to the obsolete CD4007UBM.

Alternative Selections by Packaging Format:

For Tape & Reel (TR) applications requiring high-volume automated assembly, HEF4007UBT,653 (Nexperia USA Inc.) and MC14007UBDR2G (onsemi) are functionally equivalent alternatives with active status and established supply channels.

For Tube packaging applications, MC14007UBDG (onsemi) provides an active alternative with the same packaging format as the original CD4007UBM, supporting manual or semi-automated assembly processes.

Compliance Basis: All recommended substitutes maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and legacy system maintenance. MSL 1 rating across all parts eliminates moisture sensitivity constraints during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can CD4007UBM96 directly replace CD4007UBM in existing designs?

A: Yes. CD4007UBM96 maintains identical electrical specifications (3V ~ 18V supply, -55°C ~ 125°C operating range), logic type (Complementary Pair Plus Inverter), and 14-SOIC package footprint. The only difference is packaging format (Tape & Reel vs. Tube), which does not affect circuit performance.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging is used for manual or semi-automated assembly processes, while Tape & Reel (TR) packaging is optimized for high-speed automated pick-and-place equipment. Both formats contain identical die and electrical performance. Selection depends on manufacturing process capability, not functional requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (CD4007UBM96, HEF4007UBT,653, MC14007UBDG, MC14007UBDR2G) maintain ROHS3 compliance and REACH unaffected status, meeting environmental regulations for both new production and legacy applications.

Q: Why is NLV14007UBDR2G listed but not recommended?

A: NLV14007UBDR2G is categorized as a General Purpose Comparator rather than a Complementary Pair Plus Inverter logic IC. While it shares the same 14-SOIC package and voltage range, its functional classification differs from the CD4007UBM. Direct substitution is not supported without circuit redesign.

Q: What inventory levels are available for each substitute?

A: CD4007UBM96 has 3,415 units in stock. HEF4007UBT,653 has 7,439 units. MC14007UBDG has 50,200 units. MC14007UBDR2G has 16,132 units. Inventory levels support both prototype and production-volume requirements.

Q: Is there a preferred manufacturer among the substitutes?

A: Selection should be based on supply chain requirements and packaging format needs rather than manufacturer preference. All recommended substitutes (Texas Instruments, Nexperia, onsemi) maintain equivalent electrical performance and regulatory compliance.
