FIN1022MX Equivalent & Substitute Parts

Part Overview

The FIN1022MX is a crosspoint switch IC manufactured by onsemi, configured as a 1 x 2:2 logic switch in a 16-SOIC surface mount package. This component is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production support. The part operates with a single supply voltage between 3V and 3.6V across an operating temperature range of -40°C to 85°C. Substitute parts must maintain identical electrical specifications and mechanical compatibility to ensure direct replacement capability.

Substitute Part Grouping Explanation

Substitution for the FIN1022MX is determined by strict equivalence across the following critical parameters:

Circuit Configuration: All substitute parts must maintain the 1 x 2:2 crosspoint switch topology with 1 independent circuit.

Voltage Supply: Single supply operation within the 3V to 3.6V range is mandatory.

Operating Temperature Range: All substitutes must support the full -40°C to 85°C operating window.

Package Compatibility: 16-SOIC surface mount package with 0.154" width (3.90mm) is required for mechanical and electrical compatibility.

Substitute parts are grouped into two categories: Direct Manufacturer Equivalents (functionally identical, active product status) and Parametric Equivalents (matching all electrical and mechanical specifications, including automotive-qualified variants where applicable).

Engineering Selection Recommendations

All listed substitute parts meet the core electrical and mechanical requirements for direct replacement of the FIN1022MX. Selection should be based on the following criteria:

Product Status: All substitute parts carry Active product status, ensuring long-term availability and manufacturing support compared to the obsolete FIN1022MX.

RoHS Compliance: Parts designated as ROHS3 Compliant (SN65LVCP22D, DS10CP152QMA/NOPB, DS10CP152QMAX/NOPB, DS10CP152TMAX/NOPB, DS90CP22MX-8/NOPB, MAX9152ESE+T, SN65LVCP22DR, SN65LVDS122DR) are suitable for applications requiring environmental compliance.

Automotive Qualification: DS10CP152QMA/NOPB and DS10CP152QMAX/NOPB are qualified to AEC-Q100 automotive standards and should be selected for automotive applications requiring this certification.

Packaging and Inventory: All parts are available in 16-SOIC surface mount configuration. Inventory levels vary; DS10CP152QMAX/NOPB offers the highest stock availability at 17,947 pieces.

Manufacturer Diversity: Multiple manufacturers (Texas Instruments, National Semiconductor, Analog Devices Inc./Maxim Integrated) provide substitute options, supporting supply chain flexibility.

Frequently Asked Questions (FAQ)

Q: Can any of these substitute parts be used as a direct replacement for the FIN1022MX?

A: Yes. All listed substitute parts maintain identical circuit configuration (1 x 2:2), voltage supply range (3V ~ 3.6V), operating temperature range (-40°C ~ 85°C), and 16-SOIC package specifications. Direct substitution is electrically and mechanically compatible.

Q: What is the difference between the DS10CP152 variants (QMA, QMAX, TMAX)?

A: All three DS10CP152 variants share identical electrical specifications and 16-SOIC packaging. DS10CP152QMA/NOPB and DS10CP152QMAX/NOPB are automotive-qualified (AEC-Q100), while DS10CP152TMAX/NOPB is not. Packaging differs: QMA and QMAX use Tape & Reel, while TMAX also uses Tape & Reel. Selection depends on automotive qualification requirements.

Q: Are there differences between the SN65LVCP22D and SN65LVCP22DR parts?

A: Both parts are functionally equivalent with identical electrical specifications. SN65LVCP22D is supplied in Tube packaging, while SN65LVCP22DR is supplied in Tape & Reel (TR) packaging. Selection depends on packaging and handling requirements for your production process.

Q: Which substitute part has the best inventory availability?

A: DS10CP152QMAX/NOPB offers the highest inventory level at 17,947 pieces in stock. This part is also automotive-qualified (AEC-Q100) and ROHS3 compliant, making it suitable for both standard and automotive applications.

Q: Do all substitute parts meet RoHS requirements?

A: Most substitute parts are ROHS3 compliant. DS90CP22M-8/NOPB does not specify RoHS status. Verify RoHS compliance requirements for your specific application before selection.

Q: Is the FIN1022MX still available for purchase?

A: The FIN1022MX is classified as obsolete. However, 918 pieces are reported in stock. For new designs and long-term production, selection of an active substitute part is recommended to ensure continued availability and manufacturing support.
