FIN1022MTC Equivalent & Substitute Parts

Part Overview

The FIN1022MTC is a crosspoint switch IC with 1 x 2:2 circuit configuration in 16-TSSOP surface mount packaging, manufactured by onsemi. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The part operates across a 3V to 3.6V single supply voltage range with an operating temperature range of -40°C to 85°C. Identifying compatible alternatives ensures design flexibility and supply chain resilience.

Substitute Part Grouping Explanation

Substitution for the FIN1022MTC is determined by strict equivalence across the following parameters:

Circuit configuration: 1 x 2:2
Independent circuits: 1
Voltage supply: Single supply, 3V ~ 3.6V range
Operating temperature: -40°C ~ 85°C
Package: 16-TSSOP surface mount
Moisture sensitivity: MSL 1 (Unlimited)

All substitute parts listed maintain identical electrical specifications and mechanical compatibility. Substitutes are grouped by relationship type: direct manufacturer equivalents (same base product number with different packaging or suffix codes), similar parts (same functional circuit with different series designation), and parametric equivalents (functionally identical across all specified parameters).

Engineering Selection Recommendations

For applications currently using the obsolete FIN1022MTC, the following selection criteria apply:

Primary Recommendation: DS90CP22MT/NOPB or DS90CP22MTX/NOPB (Texas Instruments). Both parts maintain active product status with ROHS3 compliance and the highest inventory availability (6600 and 2700 units respectively). The /NOPB suffix indicates lead-free, halogen-free construction. DS90CP22MTX/NOPB is supplied in Tape & Reel packaging, suitable for automated assembly; DS90CP22MT/NOPB is supplied in Tube packaging.

Secondary Options: SN65LVCP22PW, SN65LVCP23PW, SN65LVDS122PW, and SN65LVDT122PW (all Texas Instruments). These parts are active, ROHS3 compliant, and available in adequate quantities. Selection among these should be based on specific application requirements and existing supply chain relationships.

Alternative Source: MAX9152EUE+ (Analog Devices Inc./Maxim Integrated). This part is active and ROHS3 compliant with 1830 units in stock, providing supply diversification from a different manufacturer.

Avoid: DS90CP22MT (Last Time Buy status). While functionally equivalent, this part is in end-of-life phase and should not be selected for new designs.

Frequently Asked Questions (FAQ)

Q: Can I directly replace FIN1022MTC with any of the listed substitute parts?

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-TSSOP package specifications. Direct pin-for-pin and functional replacement is supported.

Q: What is the difference between DS90CP22MT/NOPB and DS90CP22MTX/NOPB?

A: Both parts are functionally identical. The primary difference is packaging: DS90CP22MT/NOPB is supplied in Tube format, while DS90CP22MTX/NOPB is supplied in Tape & Reel (TR) format. Tape & Reel packaging is optimized for automated pick-and-place assembly; Tube packaging is suitable for manual or semi-automated handling.

Q: Why are there multiple Texas Instruments part numbers listed?

A: The SN65LVCP and SN65LVDS series represent different product lines within Texas Instruments' crosspoint switch portfolio. All maintain the specified 1 x 2:2 circuit configuration and electrical parameters. Selection among these should be based on design preference, existing inventory, and supply chain considerations.

Q: Is ROHS3 compliance required for my application?

A: All active substitute parts listed are ROHS3 compliant. The original FIN1022MTC does not specify RoHS status. If your application requires RoHS certification, select from the active parts with confirmed ROHS3 compliance status.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life under normal storage conditions and requires no special moisture control during handling or storage. All listed parts maintain MSL 1 classification.

Q: Can I use parts from different manufacturers interchangeably?

A: Yes, provided all electrical and mechanical parameters match. The MAX9152EUE+ from Analog Devices Inc./Maxim Integrated is functionally equivalent to the Texas Instruments options and can be used interchangeably based on availability and supply chain strategy.
