Parameter Comparison

Engineering Selection Recommendations

Both the RT9818D-13GV and APX803L40-13SA-7 are active production devices with full ROHS3 compliance and REACH Unaffected status, making them suitable for applications requiring regulatory adherence. The devices are electrically and mechanically equivalent across all specified parameters.

Selection between these parts should be based on:

Packaging Format: The RT9818D-13GV is supplied in bulk packaging, while the APX803L40-13SA-7 is supplied in Tape & Reel format. Choose based on assembly process requirements and volume handling procedures.

Moisture Sensitivity: The APX803L40-13SA-7 features MSL 1 (Unlimited shelf life), compared to the RT9818D-13GV MSL 3 (168 hours). For applications with extended storage requirements or high-humidity environments, the APX803L40-13SA-7 offers superior moisture tolerance.

Availability: Both parts maintain substantial inventory levels (1124 and 1134 units respectively), ensuring supply continuity for production requirements.

Frequently Asked Questions (FAQ)

Q: Can the APX803L40-13SA-7 be used as a direct replacement for the RT9818D-13GV?

A: Yes. Both devices are electrically and mechanically equivalent. They share identical voltage threshold (1.3V), reset timeout (292ms minimum), output configuration (Open Drain/Open Collector), reset polarity (Active Low), operating temperature range (-40°C to 85°C), and SOT-23-3 package footprint. All regulatory certifications (ROHS3, REACH, EAR99) are matched.

Q: Are there any differences in pin configuration between these parts?

A: No. Both the RT9818D-13GV and APX803L40-13SA-7 use the SOT-23-3 package with identical three-pin configuration, ensuring direct PCB footprint compatibility without layout modifications.

Q: What is the significance of the different Moisture Sensitivity Levels?

A: The APX803L40-13SA-7 has MSL 1 (Unlimited shelf life), while the RT9818D-13GV has MSL 3 (168-hour limit). MSL 3 requires controlled storage conditions and limits shelf life to 168 hours after moisture exposure. For applications with extended storage or high-humidity environments, the APX803L40-13SA-7 provides superior moisture tolerance without additional desiccant packaging requirements.

Q: Does packaging format affect electrical performance?

A: No. The Tape & Reel (TR) packaging of the APX803L40-13SA-7 and bulk packaging of the RT9818D-13GV do not affect electrical characteristics. Packaging format selection depends on assembly process automation and volume handling requirements.

Q: Are both parts suitable for industrial temperature applications?

A: Yes. Both devices operate across the industrial temperature range of -40°C to 85°C (TA), meeting standard industrial specifications for voltage supervision and reset signal generation.

Q: What compliance standards apply to both substitute parts?

A: Both the RT9818D-13GV and APX803L40-13SA-7 are ROHS3 compliant, REACH Unaffected, and classified under ECCN EAR99 with HTSUS code 8542.39.0001, ensuring regulatory compliance for commercial and industrial applications.
