Substitute Categories:

Category 1: Direct Package & Output Type Match (14-TSSOP, Open-Drain) MCP6549-E/ST, MCP6549-I/ST, MCP6549T-E/ST, MCP6549T-I/ST, TS334IPT, and TS334IYPT maintain identical 14-TSSOP packaging and open-drain output configuration. These parts support extended supply voltage ranges (1.6V minimum) and offer improved quiescent current performance compared to the APX339TSG-13.

Category 2: Alternative Output Type (14-TSSOP, Push-Pull/CMOS) MCP6544-E/ST, MCP6544-I/ST, and MCP6544T-E/ST provide 14-TSSOP packaging with CMOS push-pull output instead of open-drain. These are suitable for applications where push-pull output is acceptable and quiescent current minimization is prioritized.

Category 3: Different Package Format (16-SOIC, Open-Drain) ADCMP396ARZ-RL7 offers open-drain output in 16-SOIC packaging. This substitute requires PCB layout modification and is applicable only when package footprint change is acceptable.

Engineering Selection Recommendations

For 14-TSSOP Open-Drain Direct Substitution: MCP6549-E/ST, MCP6549-I/ST, MCP6549T-E/ST, and MCP6549T-I/ST are functionally compatible replacements. All maintain 14-TSSOP packaging, open-drain output, and ROHS3 compliance. MCP6549T-E/ST and MCP6549T-I/ST are available in Tape & Reel format matching the APX339TSG-13 packaging preference. These parts offer superior quiescent current performance (1µA vs. 300µA) and extended operating temperature range to 125°C.

For 14-TSSOP with Extended Temperature Range: TS334IPT and TS334IYPT provide 14-TSSOP open-drain configuration with -40°C to 125°C operating range. TS334IYPT includes automotive-grade qualification (AEC-Q100). Both offer faster propagation delay (210ns vs. 600ns) and higher output current capability (93mA vs. 60mA).

For 14-TSSOP Push-Pull Output Alternative: MCP6544-E/ST, MCP6544-I/ST, and MCP6544T-E/ST provide CMOS push-pull output in 14-TSSOP packaging. These are suitable when push-pull output topology is acceptable and quiescent current minimization is required. MCP6544T-E/ST is available in Tape & Reel format.

For Package Format Change (16-SOIC): ADCMP396ARZ-RL7 offers open-drain output in 16-SOIC packaging with superior input offset voltage (2.5mV vs. 7mV) and lower quiescent current (59.4µA vs. 300µA). This substitute requires PCB layout redesign and is applicable only when package footprint modification is feasible.

Compliance Considerations: All substitute parts maintain ROHS3 compliance and active product status. Selection should prioritize parts with matching operating temperature requirements and packaging format to minimize design and procurement modifications.

Frequently Asked Questions (FAQ)

Q: Can MCP6549 series parts directly replace APX339TSG-13 without circuit modification? A: MCP6549-E/ST, MCP6549-I/ST, MCP6549T-E/ST, and MCP6549T-I/ST are pin-compatible and functionally equivalent in 14-TSSOP packaging with identical open-drain output configuration. No circuit modification is required for these substitutes.

Q: What is the difference between MCP6549-E/ST and MCP6549T-E/ST? A: Both parts are electrically identical. The primary difference is packaging format: MCP6549-E/ST is supplied in Tube packaging, while MCP6549T-E/ST is supplied in Tape & Reel (TR) format. MCP6549T-E/ST matches the APX339TSG-13 Tape & Reel packaging preference.

Q: Are MCP6544 series parts suitable replacements for open-drain applications? A: MCP6544 series parts feature CMOS push-pull output instead of open-drain. These are suitable only for applications where push-pull output topology is acceptable. Applications requiring open-drain output should use MCP6549 series instead.

Q: What are the key performance differences between APX339TSG-13 and TS334IPT? A: TS334IPT offers faster propagation delay (210ns vs. 600ns), higher output current capability (93mA vs. 60mA), lower input offset voltage (5mV vs. 7mV), and extended operating temperature range (-40°C to 125°C vs. -40°C to 85°C). Both maintain 14-TSSOP packaging and open-drain output.

Q: Can ADCMP396ARZ-RL7 be used as a substitute despite different packaging? A: ADCMP396ARZ-RL7 is functionally compatible but requires PCB layout modification due to 16-SOIC packaging versus 14-TSSOP. This substitute is applicable only when package footprint change is acceptable and superior input offset voltage performance is required.

Q: What is the moisture sensitivity level difference between APX339TSG-13 and substitute parts? A: APX339TSG-13 has MSL 3 (168 Hours), while most substitute parts have MSL 1 (Unlimited). Lower MSL values indicate reduced moisture sensitivity and longer shelf life without baking requirements.

Q: Are all substitute parts ROHS3 compliant? A: Yes, all listed substitute parts maintain ROHS3 compliance matching the APX339TSG-13 environmental certification status.

Q: Which substitute offers the lowest quiescent current consumption? A: MCP6549 series parts (MCP6549-E/ST, MCP6549-I/ST, MCP6549T-E/ST, MCP6549T-I/ST) and MCP6544 series parts offer 1µA maximum quiescent current, significantly lower than APX339TSG-13 (300µA).

Q: Is TS334IYPT suitable for automotive applications? A: Yes, TS334IYPT includes automotive-grade qualification (AEC-Q100) and is suitable for automotive applications requiring -40°C to 125°C operating temperature range with 14-TSSOP open-drain configuration.
