CD4082BPW Equivalent & Substitute Parts

Part Overview

The CD4082BPW is a 2-channel AND gate logic IC manufactured by Texas Instruments, housed in a 14-TSSOP surface mount package. This component operates across a wide supply voltage range of 3V to 18V and is part of the 4000B CMOS logic series. The CD4082BPW is currently in Last Time Buy status, indicating limited availability. Identifying equivalent substitute parts is necessary to ensure design continuity and maintain supply chain reliability for applications requiring this logic function.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4082BPW is determined by strict equivalence across the following critical parameters:

• Logic function: 2-channel AND gate with 4 inputs per channel
• Electrical specifications: Supply voltage range 3V ~ 18V, quiescent current 1 µA maximum, output current 3.4mA, propagation delay 90ns @ 15V with 50pF load
• Package type: 14-TSSOP surface mount configuration
• Temperature range: -55°C ~ 125°C
• Compliance: ROHS3 compliant, MSL Level 1

The CD4082BPWR meets all these criteria and is therefore a direct functional and electrical equivalent. The primary distinction between these parts is packaging format: the CD4082BPW is supplied in Tube packaging, while the CD4082BPWR is supplied in Cut Tape (CT) & Digi-Reel® format.

Parameter Comparison

Engineering Selection Recommendations

The CD4082BPWR is the direct substitute for the CD4082BPW. Both parts are manufactured by Texas Instruments and share identical electrical and functional specifications. The CD4082BPWR is currently in Active product status with higher inventory availability (3220 Pcs) compared to the CD4082BPW (762 Pcs), which is in Last Time Buy status. Both parts maintain ROHS3 compliance and MSL Level 1 rating.

The selection between these parts should be based on packaging requirements and supply chain considerations. The CD4082BPWR in Cut Tape & Digi-Reel® format is suitable for automated assembly processes and high-volume production. The CD4082BPW in Tube packaging may be preferred for manual assembly or lower-volume applications where tape reel handling is not required.

Frequently Asked Questions (FAQ)

Q: Are CD4082BPW and CD4082BPWR electrically identical?

A: Yes. Both parts are manufactured by Texas Instruments and share identical electrical specifications, including supply voltage range (3V ~ 18V), quiescent current (1 µA max), output current (3.4mA), propagation delay (90ns @ 15V, 50pF), and operating temperature range (-55°C ~ 125°C).

Q: What is the difference between these two part numbers?

A: The primary difference is packaging format. The CD4082BPW is supplied in Tube packaging, while the CD4082BPWR is supplied in Cut Tape (CT) & Digi-Reel® format. Both use the same 14-TSSOP surface mount package.

Q: Can I use CD4082BPWR as a direct replacement for CD4082BPW in my design?

A: Yes. The CD4082BPWR is a direct functional and electrical equivalent. No circuit modifications are required. The 14-TSSOP package footprint is identical for both parts.

Q: Why is CD4082BPW in Last Time Buy status?

A: Last Time Buy status indicates that Texas Instruments is discontinuing this product variant. The CD4082BPWR in Active status is the recommended alternative for new designs and ongoing production.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: Which part should I specify for new production?

A: The CD4082BPWR is recommended for new production due to its Active product status and higher inventory availability. It is suitable for automated assembly processes using tape reel packaging.
