HEF4072BT,652 Equivalent & Substitute Parts

Part Overview

The HEF4072BT,652 is a 2-channel OR gate logic IC manufactured by NXP USA Inc., housed in a 14-SO surface mount package. This component belongs to the 4000B CMOS logic series and is classified as obsolete. Due to its discontinued status, identifying functionally equivalent substitute parts is necessary for ongoing design support, board revisions, and production continuity. Substitute parts must maintain identical logic functionality, pin configuration, and electrical performance within specified operating ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HEF4072BT,652 is based on the following critical parameters:

• Logic Function: All substitute parts must implement 2-channel OR gate logic with 4 inputs per channel
• Package Compatibility: Substitute parts must use 14-SOIC or 14-SO surface mount packages with identical pin assignments
• Voltage Supply Range: The main part operates at 3V ~ 15V; substitute parts with extended ranges (3V ~ 18V) are compatible within the original operating window
• Operating Temperature: The main part range is -40°C ~ 85°C; substitute parts with extended ranges (-55°C ~ 125°C) provide broader environmental coverage
• Series Classification: All parts belong to the 4000B CMOS logic series
• Compliance: RoHS3 compliance and REACH unaffected status must be maintained

The four substitute parts (CD4072BM, CD4072BM96, CD4072BMT, CD4072BNSR) are all manufactured by Texas Instruments and meet these substitution criteria. Differences exist only in packaging format (Tube, Cut Tape & Digi-Reel, or Tape & Reel) and product status (Active or Discontinued at DiGi Electronics).

Parameter Comparison

Engineering Selection Recommendations

CD4072BM96 (Texas Instruments) is the primary recommended substitute. This part carries Active product status, ensuring long-term availability and manufacturing support. It is supplied in Cut Tape & Digi-Reel format with 9656 units in stock, providing reliable procurement for production environments. The extended voltage supply range (3V ~ 18V) and operating temperature range (-55°C ~ 125°C) exceed the original part specifications, offering design margin for environmental variations.

CD4072BNSR (Texas Instruments) is the secondary recommended substitute. This part also maintains Active product status and is supplied in Tape & Reel format with 2000 units in stock. Note that this variant uses a 14-SOIC package with 0.209" width (5.30mm) compared to the standard 0.154" width (3.90mm). PCB layout verification is required to confirm mechanical compatibility before selection.

CD4072BM (Texas Instruments) and CD4072BMT (Texas Instruments) are available but carry Discontinued at DiGi Electronics status. These parts should be considered only when CD4072BM96 or CD4072BNSR are unavailable. CD4072BM is supplied in Tube format (1225 units in stock), while CD4072BMT is supplied in Cut Tape & Digi-Reel format (832 units in stock).

All substitute parts maintain identical logic functionality, input/output thresholds, and compliance certifications. The primary performance difference is propagation delay: substitute parts exhibit 90ns maximum delay at 15V and 50pF load, compared to 55ns for the original part. This difference must be evaluated against circuit timing requirements.

Frequently Asked Questions (FAQ)

Q: Can CD4072BM96 be used as a direct replacement for HEF4072BT,652?

A: Yes. Both parts implement identical 2-channel OR gate logic with 4 inputs per channel in 14-SOIC surface mount packages. Electrical parameters (input/output thresholds, supply voltage range, operating temperature) are compatible. Pin assignments are identical. The primary difference is propagation delay (90ns vs. 55ns), which must be verified against circuit timing specifications.

Q: What is the difference between CD4072BM96 and CD4072BNSR?

A: Both parts are manufactured by Texas Instruments and implement identical logic functionality. The primary difference is package width: CD4072BM96 uses 14-SOIC (0.154", 3.90mm width), while CD4072BNSR uses 14-SOIC (0.209", 5.30mm width). PCB footprint compatibility must be confirmed before selection. Both maintain Active product status.

Q: Why does the substitute part have a longer propagation delay (90ns vs. 55ns)?

A: Propagation delay differences reflect manufacturing process variations between NXP and Texas Instruments. The 90ns specification for Texas Instruments CD4072 parts is within acceptable CMOS logic performance for the 4000B series. Circuit timing analysis must confirm that the longer delay does not violate system requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All four substitute parts (CD4072BM, CD4072BM96, CD4072BMT, CD4072BNSR) are RoHS3 compliant and REACH unaffected, matching the compliance status of the original HEF4072BT,652.

Q: Which substitute part should I select for new production?

A: CD4072BM96 is recommended for new production due to Active product status, highest inventory availability (9656 units), and standard 14-SOIC package dimensions (0.154", 3.90mm width). This ensures long-term supply continuity and compatibility with existing PCB designs.

Q: Can I use CD4072BNSR if CD4072BM96 is unavailable?

A: CD4072BNSR is functionally equivalent and maintains Active product status. However, verify PCB footprint compatibility due to the wider 14-SOIC package (0.209", 5.30mm width vs. 0.154", 3.90mm width). If the PCB footprint is designed for the narrower package, mechanical interference may occur.
