CAT810SSDI-T3 Equivalent & Substitute Parts

Part Overview

The CAT810SSDI-T3 is a single-channel power supply supervisor IC manufactured by onsemi, designed for simple reset and power-on reset applications. This component monitors a single voltage threshold at 2.93V and provides push-pull, totem pole output with active high reset signaling. The device is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CAT810SSDI-T3 is determined by strict alignment of the following critical parameters:

• Single voltage monitoring channel
• 2.93V threshold voltage
• Push-pull, totem pole output configuration
• Active high reset logic
• 140ms minimum reset timeout
• SC-70 / SOT-323 package compatibility
• Surface mount technology
• Operating temperature range compatibility

Two substitute parts meet these criteria:

Direct Substitute: MIC810SYC3-TR (Microchip Technology) — Functionally identical across all specified parameters with active product status.

Similar Substitute: MAX810SEXR+T (Analog Devices Inc./Maxim Integrated) — Meets all electrical and mechanical requirements with extended operating temperature range (-40°C ~ 125°C).

Parameter Comparison

Engineering Selection Recommendations

MIC810SYC3-TR is the primary substitute for direct replacement applications. This part maintains identical electrical specifications and package configuration while offering active product status and ROHS3 compliance. Tape & Reel packaging supports high-volume manufacturing requirements.

MAX810SEXR+T provides an alternative with extended operating temperature range to 125°C, suitable for applications requiring enhanced thermal performance beyond the original -40°C ~ 85°C specification. This part also carries active product status and ROHS3 compliance.

Both substitutes are classified as REACH Unaffected and carry EAR99 ECCN designation, matching the regulatory profile of the original component.

Frequently Asked Questions (FAQ)

Q: Can MIC810SYC3-TR replace CAT810SSDI-T3 in existing designs?

A: Yes. MIC810SYC3-TR meets all electrical and mechanical specifications of CAT810SSDI-T3, including voltage threshold, output configuration, reset timing, and package geometry. Pin-for-pin compatibility is maintained.

Q: What is the difference between MIC810SYC3-TR and MAX810SEXR+T?

A: Both parts satisfy the core substitution criteria. The primary difference is operating temperature range: MIC810SYC3-TR operates -40°C ~ 85°C (matching the original), while MAX810SEXR+T extends to 125°C. Select MAX810SEXR+T for applications requiring higher temperature performance.

Q: Are there packaging differences between these substitutes?

A: All three parts use SC-70 / SOT-323 surface mount packages. MIC810SYC3-TR is supplied in Tape & Reel format; packaging for MAX810SEXR+T is also Tape & Reel. Physical footprint and pin configuration are identical.

Q: Do the substitutes carry the same compliance certifications?

A: MIC810SYC3-TR and MAX810SEXR+T both carry ROHS3 compliance and REACH Unaffected status. All three parts share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Q: Is the reset timeout specification identical across all three parts?

A: Yes. All three parts specify 140ms minimum reset timeout, ensuring equivalent timing behavior in power-on reset and supervisory applications.
