Substitute Part Grouping Explanation

Substitution of the CD40107BPW is determined by strict equivalence across the following critical parameters:

• Logic Function: Dual 2-input NAND gate with open drain output configuration
• Electrical Specifications: Supply voltage range 3V ~ 18V, quiescent current 4 µA maximum, output current 68mA maximum, propagation delay 100ns @ 15V with 50pF load
• Input Logic Levels: Low 1.5V ~ 4V, High 4.6V ~ 11V
• Package Format: 8-TSSOP surface mount package with identical physical dimensions
• Temperature Range: -55°C ~ 125°C operating specification
• Compliance Standards: ROHS3 compliant, REACH unaffected, EAR99 classification

The CD40107BPWR represents a direct functional equivalent, differing only in packaging configuration (Tape & Reel versus Tube) while maintaining identical electrical performance and pin compatibility.

Parameter Comparison

Engineering Selection Recommendations

The CD40107BPWR is the direct substitute for the CD40107BPW. Both components are manufactured by Texas Instruments and maintain identical electrical and functional specifications across all critical parameters. The primary distinction is packaging format: the CD40107BPW is supplied in Tube packaging, while the CD40107BPWR is supplied in Tape & Reel format.

Selection between these parts should be based on procurement and assembly requirements. The CD40107BPWR is recommended for high-volume production environments utilizing automated pick-and-place assembly, as Tape & Reel packaging is optimized for such processes. The CD40107BPW remains suitable for lower-volume applications or manual assembly workflows.

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), ensuring compatibility with standard manufacturing and storage protocols. The CD40107BPWR's Active product status provides extended availability compared to the CD40107BPW's Last Time Buy designation.

Frequently Asked Questions (FAQ)

Q: Are CD40107BPW and CD40107BPWR pin-compatible? A: Yes. Both components use the 8-TSSOP package with identical pin assignments and electrical characteristics. Direct substitution is possible without circuit modification.

Q: What is the difference between Tube and Tape & Reel packaging? A: Tube packaging supplies individual components in a plastic tube, suitable for manual handling and lower-volume applications. Tape & Reel packaging supplies components on continuous carrier tape wound on reels, optimized for automated assembly equipment. Electrical performance is identical.

Q: Can I use CD40107BPWR in place of CD40107BPW? A: Yes. The CD40107BPWR is a direct functional equivalent with identical electrical specifications, operating temperature range, and supply voltage requirements. Substitution is valid for all applications.

Q: Why is CD40107BPW marked as Last Time Buy? A: Last Time Buy status indicates the manufacturer is discontinuing production. The CD40107BPWR, with Active status, represents the ongoing production equivalent and is recommended for new designs or long-term supply requirements.

Q: Are there any compliance differences between these parts? A: No. Both parts maintain identical ROHS3 compliance, REACH unaffected status, and EAR99 classification. Moisture sensitivity level (MSL 1) is identical for both variants.

Q: What is the maximum output current for this NAND gate? A: The maximum output low current is 68mA. The output high current is not specified (indicated by "-"), which is typical for open drain configurations where external pull-up resistors determine high-level current characteristics.
