CAT130019SWI-G Equivalent & Substitute Parts
Part Overview
The CAT130019SWI-G is a Power Management Integrated Circuit (PMIC) supervisor with push-pull, totem pole output configuration. This component functions as a simple reset/power-on reset supervisor, monitoring a single voltage channel with a 2.93V threshold and 140ms minimum reset timeout. The device is packaged in an 8-SOIC surface mount package.
The CAT130019SWI-G is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this supervisor IC.

Engineering Selection Recommendations
All identified substitute parts provide parametric equivalence to the CAT130019SWI-G across electrical and mechanical specifications. Selection among substitutes should be based on the following factors:
Active Product Status: ADM709SARZ, MAX706ASESA+, MAX706SESA+, MAX709SESA+, and TPS3705-33D are all classified as active products with ongoing manufacturer support and supply chain availability. TPS3705-33DG4 is discontinued at DiGi Electronics and should be considered only if existing inventory is available and long-term supply is not a requirement.
Compliance and Certifications: All active substitute parts are ROHS3 compliant and carry EAR99 ECCN classification, meeting current regulatory requirements for electronic component distribution and use.
Inventory Availability: Substitute parts are available in varying quantities. Selection may be influenced by immediate procurement needs and lead time requirements.
Manufacturer Support: Analog Devices Inc./Maxim Integrated and Texas Instruments provide comprehensive technical documentation and ongoing product support for their respective supervisor IC lines.
Frequently Asked Questions (FAQ)
Q: Can the CAT130019SWI-G be directly replaced with any of these substitute parts?
A: Yes. All identified substitute parts are parametrically equivalent across voltage threshold (2.93V), output configuration (push-pull, totem pole), reset logic (active low), reset timeout (140ms minimum), package type (8-SOIC), operating temperature range (-40°C ~ 85°C), and moisture sensitivity level (MSL 1). Direct pin-for-pin and functional replacement is supported.
Q: What is the difference between the MAX706 and MAX709 series substitutes?
A: Both the MAX706ASESA+, MAX706SESA+, and MAX709SESA+ meet all parametric requirements for substitution. The differences between these part numbers relate to internal design variants and manufacturing specifications not provided in the parametric data. Consult manufacturer datasheets for detailed functional differences if required.
Q: Are there any package or mounting differences between the CAT130019SWI-G and the substitute parts?
A: No. All substitute parts use the same 8-SOIC (0.154", 3.90mm Width) surface mount package. PCB layout and assembly processes require no modification.
Q: Which substitute part should I select for new designs?
A: For new designs, select from parts with active product status: ADM709SARZ, MAX706ASESA+, MAX706SESA+, MAX709SESA+, or TPS3705-33D. All provide equivalent functionality with ongoing manufacturer support and supply chain availability.
Q: Is the TPS3705-33DG4 a viable substitute?
A: The TPS3705-33DG4 is parametrically equivalent but is discontinued at DiGi Electronics. It may be considered only if existing inventory is available and supply chain continuity is not a concern for your application.
Q: Do all substitute parts meet RoHS compliance?
A: Yes. All active substitute parts (ADM709SARZ, MAX706ASESA+, MAX706SESA+, MAX709SESA+, TPS3705-33D, and TPS3705-33DG4) are ROHS3 compliant and meet current environmental and regulatory standards.
