HEF4072BT,653 Equivalent & Substitute Parts

Part Overview

The HEF4072BT,653 is a 2-channel OR gate logic IC manufactured by NXP USA Inc., housed in a 14-SOIC surface mount package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The HEF4072BT,653 operates across a 3V to 15V supply voltage range and is suitable for digital logic applications requiring OR gate functionality with dual 4-input configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HEF4072BT,653 are qualified based on the following criteria:

• Logic Function: All substitutes must implement 2-channel OR gate logic with 4 inputs per channel
• Package Compatibility: All substitutes use 14-SOIC surface mount packaging with identical physical dimensions (0.154", 3.90mm width)
• Series Classification: All substitutes belong to the 4000B logic series
• Supply Voltage Range: Substitutes must support the minimum 3V supply requirement; extended upper voltage ratings (up to 18V) are acceptable
• Output Current Capability: Substitutes must meet or exceed the 3mA output current specification
• Compliance Standards: All substitutes maintain ROHS3 compliance and MSL Level 1 rating
• Propagation Delay: Substitutes with longer propagation delays remain functionally compatible for non-time-critical applications

The Texas Instruments CD4072 series parts (CD4072BM, CD4072BM96, CD4072BMT) meet all substitution criteria while offering extended operating temperature ranges and improved quiescent current characteristics.

Parameter Comparison

Engineering Selection Recommendations

CD4072BM96 is the primary recommended substitute for the HEF4072BT,653. This part maintains active product status, ensuring long-term availability and supply chain stability. The CD4072BM96 is supplied in Cut Tape (CT) & Digi-Reel® packaging with 9656 units currently in stock, providing immediate procurement capability. All electrical and mechanical parameters align with substitution requirements, and ROHS3 compliance with MSL Level 1 rating ensures compatibility with standard manufacturing processes.

CD4072BMT serves as a secondary substitute option. Although discontinued at DiGi Electronics, this part meets all electrical and mechanical compatibility criteria with 832 units available in inventory. Selection of this part should be based on specific packaging requirements (Cut Tape & Digi-Reel®) or supply chain constraints.

CD4072BM is a tertiary option, discontinued at DiGi Electronics but available in Tube packaging with 1225 units in stock. This part is suitable for applications where tube packaging is preferred over cut tape formats.

All three Texas Instruments substitutes provide superior quiescent current performance (1 µA versus 4 µA) and extended operating temperature ranges (-55°C to 125°C versus -40°C to 85°C), offering design advantages for temperature-sensitive or low-power applications.

Frequently Asked Questions (FAQ)

Q: Can CD4072BM96 directly replace HEF4072BT,653 in existing designs?

A: Yes. Both parts implement identical 2-channel OR gate logic with 4 inputs per channel in 14-SOIC packaging. Electrical parameters are compatible across all specified operating conditions. The extended supply voltage range (3V to 18V) and wider operating temperature range (-55°C to 125°C) of the CD4072BM96 provide additional design margin.

Q: What is the difference between CD4072BM, CD4072BM96, and CD4072BMT?

A: These parts are electrically identical but differ in packaging format and product status. CD4072BM96 is the active product supplied in Cut Tape & Digi-Reel® format. CD4072BMT is discontinued but also supplied in Cut Tape & Digi-Reel® format. CD4072BM is discontinued and supplied in Tube packaging. Selection depends on packaging requirements and availability.

Q: Are there any timing considerations when substituting the HEF4072BT,653?

A: The CD4072 series substitutes exhibit longer propagation delay (90ns at 15V, 50pF) compared to the HEF4072BT,653 (55ns). For applications with timing-critical signal paths, this 35ns difference must be evaluated against system timing budgets. For non-time-critical logic applications, this difference is not significant.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All substitute parts are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating, matching the HEF4072BT,653 specifications. REACH status is unaffected for all parts.

Q: What is the advantage of the extended operating temperature range in CD4072 substitutes?

A: The CD4072 series operates from -55°C to 125°C compared to the HEF4072BT,653 range of -40°C to 85°C. This extended range accommodates industrial and automotive applications requiring operation at lower ambient temperatures or higher junction temperatures without performance degradation.
