Engineering Selection Recommendations

Primary Recommendation: PCA9601DPZ The PCA9601DPZ is the preferred substitute, maintaining NXP manufacturer continuity with Active product status. It provides identical package (8-TSSOP), voltage supply range (2.5V ~ 15V), and data rate capability (1MHz). The addition of a second channel and 100ns delay time specification represents functional enhancement without compatibility compromise. This part is recommended for designs requiring direct form-factor and electrical compatibility with the obsolete PCA9601DP,118.

Secondary Recommendations: P82B96 Series (Texas Instruments) The P82B96 family offers multiple packaging options (8-TSSOP, 8-SOIC, 8-DIP, 8-VSSOP) with Active status availability. These parts operate at 400kHz data rate, which is within the I2C standard specification. The P82B96PWR (8-TSSOP, Active) and P82B96DR (8-SOIC, Active) provide the best long-term availability. Lower supply current (4mA vs. 5.5mA) and extended voltage floor (2V vs. 2.5V) represent operational advantages. Selection depends on PCB layout constraints and packaging requirements.

Alternative for Single-Channel Requirements: P82B715 Series For applications requiring single-channel configuration, the P82B715DR (8-SOIC, Active) or P82B715P (8-DIP, Active) provide I2C buffer functionality. These parts operate within a narrower voltage range (4.5V ~ 12V) and exhibit higher supply current (22mA). Selection of this family requires verification that the application voltage supply and current budget accommodate these specifications.

Compliance Assurance All recommended substitutes maintain ROHS3 compliance and operate across the -40°C to 85°C temperature range, ensuring regulatory and thermal compatibility with the original PCA9601DP,118 design requirements.

Frequently Asked Questions (FAQ)

Q: Can PCA9601DPZ directly replace PCA9601DP,118 in existing designs? A: Yes. The PCA9601DPZ maintains identical 8-TSSOP package dimensions, voltage supply range (2.5V ~ 15V), and 1MHz data rate. The additional channel and delay time specification do not create incompatibility. Pin-to-pin compatibility must be verified against the specific PCB layout.

Q: What is the primary difference between PCA9601DPZ and P82B96 series substitutes? A: PCA9601DPZ maintains 1MHz data rate capability and 2.5V minimum supply voltage. P82B96 series operates at 400kHz maximum data rate with 2V minimum supply voltage. For I2C applications, 400kHz meets standard bus speed requirements. Selection depends on whether the design requires 1MHz operation or can operate within standard I2C clock speeds.

Q: Are through-hole packages available as substitutes? A: Yes. The P82B96P (8-DIP) and P82B715P (8-DIP) provide through-hole mounting options. These parts are suitable for breadboard prototyping or legacy PCB designs requiring through-hole components. Both maintain ROHS3 compliance and I2C application compatibility.

Q: What packaging options are available for surface mount designs? A: Surface mount options include 8-TSSOP (PCA9601DPZ, P82B96PW, P82B96PWR), 8-SOIC (P82B96D, P82B96DR, P82B715D, P82B715DR), and 8-VSSOP (P82B96DGKR). The 8-TSSOP option most closely matches the original PCA9601DP,118 form factor.

Q: Which substitute offers the best long-term availability? A: P82B96PWR and P82B96DR both carry Active product status with substantial inventory levels (15,600 and 37,600 units respectively). These parts represent the most stable long-term sourcing options.

Q: Do substitute parts require circuit design modifications? A: No circuit modifications are required for I2C bus applications. All substitutes maintain 2-Wire Bus input/output configuration and operate within compatible voltage and temperature ranges. PCB layout considerations may apply based on package selection.

Q: What is the significance of "Last Time Buy" product status? A: Parts marked "Last Time Buy" (P82B96D, P82B96PW, P82B715D) indicate the manufacturer will discontinue production. These parts remain available for current orders but should not be selected for new long-term production designs. Active status parts are recommended for new designs.

Q: Can I use P82B715 series as a substitute for single-channel applications? A: Yes, if the application voltage supply range (4.5V ~ 12V) and higher supply current (22mA) are compatible with the design. The P82B715DR (8-SOIC, Active) is the recommended single-channel option with confirmed long-term availability.
