CD4025BM NOR Gate IC Equivalent & Substitute Parts

Part Overview

The CD4025BM is a 3-channel NOR gate logic IC manufactured by Texas Instruments in the 4000B series. This surface mount device operates across a wide supply voltage range of 3V to 18V and is housed in a 14-SOIC package. The CD4025BM is currently in Last Time Buy status, making identification of active equivalent and substitute parts essential for ongoing design support and procurement planning. Alternative parts with identical or compatible electrical and mechanical specifications ensure design continuity and supply chain flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4025BM is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Logic Type: NOR Gate (3-channel, 3-input configuration)
• Package: 14-SOIC form factor
• Supply Voltage Range: 3V ~ 18V
• Operating Temperature: -55°C ~ 125°C
• RoHS and REACH Compliance Status

Substitution Categories:

Category 1: Direct Functional Equivalents (Identical Specifications) Parts meeting all electrical parameters including output current (3.4mA) and propagation delay (90ns @ 15V, 50pF):

• CD4025BM96 (Texas Instruments, Active status, Cut Tape & Digi-Reel packaging)

Category 2: Functional Equivalents with Parameter Variance (Higher Output Current) Parts with identical logic configuration and package but higher output current capability (8.8mA) and slightly increased propagation delay (100ns @ 15V, 50pF):

• MC14025BDR2G (onsemi, Tape & Reel packaging)
• MC14025BDG (onsemi, Tube packaging)
• NLV14025BDR2G (onsemi, Tape & Reel packaging)

Category 3: Functional Alternative (Different Logic Type) Part with different logic function but identical package and supply specifications:

• CD4069UBM (Texas Instruments, Inverter IC, 6-channel configuration)

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance): CD4025BM96 is the primary recommended substitute. This part maintains identical output current specifications (3.4mA) and propagation delay (90ns @ 15V, 50pF) while offering Active product status and improved packaging availability through Cut Tape & Digi-Reel format. Both parts are Texas Instruments products within the 4000B series, ensuring design continuity.

For Active Supply with Parameter Tolerance: MC14025BDR2G, MC14025BDG, and NLV14025BDR2G are onsemi equivalents suitable for applications where higher output current (8.8mA) and slightly increased propagation delay (100ns @ 15V, 50pF) are acceptable. All three maintain the 14-SOIC package, supply voltage range, and operating temperature specifications. These parts offer robust Active status and established supply chains.

For Alternative Logic Function: CD4069UBM is not a direct substitute due to different logic type (Inverter vs. NOR Gate) and circuit configuration (6-channel, 1-input vs. 3-channel, 3-input). This part is listed only for reference in applications where inverter functionality may serve as a design alternative.

Compliance Considerations: All substitute parts maintain ROHS3 compliance, REACH Unaffected status, and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can CD4025BM96 be used as a direct replacement for CD4025BM? A: Yes. CD4025BM96 is electrically and mechanically identical to CD4025BM, with matching output current (3.4mA) and propagation delay (90ns @ 15V, 50pF) specifications. The primary difference is packaging format (Cut Tape & Digi-Reel vs. Tube) and Active product status.

Q: What is the difference between the Texas Instruments and onsemi NOR gate options? A: Texas Instruments parts (CD4025BM, CD4025BM96) deliver 3.4mA output current and 90ns propagation delay. onsemi parts (MC14025BDR2G, MC14025BDG, NLV14025BDR2G) provide higher output current (8.8mA) and slightly increased propagation delay (100ns @ 15V, 50pF). Both families maintain identical supply voltage range, operating temperature, and package specifications.

Q: Are packaging differences between Tube, Cut Tape, and Tape & Reel significant for substitution? A: Packaging format affects procurement, handling, and assembly processes but does not impact electrical performance or compatibility. Selection depends on manufacturing requirements and inventory management practices. All formats are compatible with standard surface mount assembly equipment.

Q: Can CD4069UBM replace CD4025BM in my design? A: No. CD4069UBM is a 6-channel Inverter IC with fundamentally different logic function and circuit configuration. It cannot perform NOR gate operations and is unsuitable as a direct substitute. Consider this part only if your design can accommodate inverter functionality.

Q: Do all substitute parts meet the same compliance standards? A: Yes. All listed substitute parts maintain ROHS3 compliance, REACH Unaffected status, and MSL Level 1 rating, matching the CD4025BM compliance profile.

Q: What should I consider when transitioning from CD4025BM (Last Time Buy) to an active substitute? A: Verify that the selected substitute meets your specific output current and propagation delay requirements. CD4025BM96 provides identical electrical specifications for seamless transition. onsemi alternatives require confirmation that higher output current (8.8mA) and increased propagation delay (100ns) are acceptable for your application timing and drive requirements.
