Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the APX393SG-13 is determined by the following critical parameters:

Functional Requirements:

• Dual-channel comparator configuration (2 elements)
• General purpose or equivalent application class
• Open-drain output capability
• Surface mount packaging in 8-pin configuration

Electrical Compatibility:

• Supply voltage range must encompass or overlap with 2.5V ~ 5.5V
• Input offset voltage within acceptable tolerance for signal comparison applications
• Propagation delay suitable for timing-critical applications (≤ 600ns preferred)
• Quiescent current within reasonable operational limits

Physical & Environmental:

• 8-pin SOIC or equivalent compact surface mount package
• Operating temperature range of -40°C ~ 85°C minimum
• RoHS3 compliance and REACH unaffected status
• MSL rating compatible with standard assembly processes

Substitute parts meeting these criteria can be directly interchanged in applications where the APX393SG-13 is specified, provided PCB layout accommodates package variations and electrical performance margins are verified for the specific application.

Parameter Comparison

Engineering Selection Recommendations

ADCMP392ARZ-RL7 (Analog Devices Inc.)

This substitute offers identical 8-SOIC package footprint compatibility with the APX393SG-13. The ADCMP392ARZ-RL7 provides superior input offset voltage performance (5mV vs. 7mV) and significantly lower quiescent current (29.3µA vs. 180µA), making it suitable for power-sensitive applications. The extended operating temperature range (-40°C ~ 125°C) provides additional thermal margin. However, the propagation delay specification (9.7µs) exceeds the APX393SG-13 (600ns), requiring verification for timing-critical applications. Both devices are ROHS3 compliant and active in production.

BU7253F-E2 (Rohm Semiconductor)

This CMOS comparator provides open-drain output matching the APX393SG-13 architecture. The BU7253F-E2 features exceptionally low input bias current (1pA typical) and operates across an extended supply voltage range (1.8V ~ 5.5V). The package width differs slightly (4.40mm vs. 3.90mm), requiring PCB layout verification. Propagation delay (750ns typical) is comparable to the APX393SG-13. This device is ROHS3 compliant and active in production with MSL rating of 1 (Unlimited).

TS332IQ2T (STMicroelectronics)

This substitute employs a compact 8-DFN (2x2) package rather than SOIC, necessitating PCB redesign. The TS332IQ2T delivers higher output current capability (93mA @ 5V vs. 60mA @ 5V) and lower quiescent current (30µA vs. 180µA). Propagation delay (720ns) is within acceptable range of the APX393SG-13. Extended operating temperature range (-40°C ~ 125°C) and MSL rating of 1 (Unlimited) provide additional design flexibility. ROHS3 compliance is confirmed.

All substitute parts maintain active product status, ROHS3 compliance, and REACH unaffected designation, ensuring regulatory and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the ADCMP392ARZ-RL7 be used as a direct replacement for the APX393SG-13?

A: The ADCMP392ARZ-RL7 shares identical 8-SOIC package dimensions and dual-channel comparator architecture. However, the propagation delay specification (9.7µs) is significantly longer than the APX393SG-13 (600ns). Direct substitution is valid only when application timing requirements do not depend on the faster propagation delay of the original part.

Q: What is the primary difference between the BU7253F-E2 and APX393SG-13?

A: Both devices feature open-drain output and dual-channel configuration. The BU7253F-E2 is classified as CMOS technology with exceptionally low input bias current (1pA typical). The package width differs (4.40mm vs. 3.90mm), and the BU7253F-E2 operates across a wider supply voltage range (1.8V ~ 5.5V). PCB layout verification is required due to package dimension variation.

Q: Why does the TS332IQ2T use a different package type?

A: The TS332IQ2T employs an 8-DFN (2x2) package, which is a compact surface mount alternative to SOIC. This package type offers reduced board space and improved thermal characteristics. Substitution requires PCB redesign and is not a pin-compatible replacement.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The APX393SG-13 and all listed substitute parts (ADCMP392ARZ-RL7, BU7253F-E2, TS332IQ2T) are ROHS3 compliant and REACH unaffected, ensuring regulatory compliance across all options.

Q: Which substitute part has the lowest quiescent current?

A: The ADCMP392ARZ-RL7 offers the lowest maximum quiescent current at 29.3µA, compared to 180µA for the APX393SG-13. The BU7253F-E2 and TS332IQ2T provide 65µA and 30µA respectively, both significantly lower than the original part.

Q: Can the TS332IQ2T operate at the same supply voltage as the APX393SG-13?

A: The TS332IQ2T operates across 1.6V ~ 5V, which overlaps with the APX393SG-13 range of 2.5V ~ 5.5V. At 5V operation, both devices function within specification. However, the TS332IQ2T cannot operate above 5V, whereas the APX393SG-13 supports up to 5.5V.

Q: What is the MSL rating significance for these comparators?

A: MSL (Moisture Sensitivity Level) indicates the maximum time a component can be exposed to ambient conditions before soldering. The APX393SG-13 has MSL 3 (168 hours), while ADCMP392ARZ-RL7, BU7253F-E2, and TS332IQ2T all have MSL 1 (Unlimited). Lower MSL ratings provide greater flexibility in assembly scheduling and storage.
