FIN1215MTD Equivalent & Substitute Parts

Part Overview

The FIN1215MTD is a 1.785Gbps serializer interface IC manufactured by onsemi, designed for converting 21 LVTTL inputs to 3 LVDS outputs in a 48-TSSOP package. This part is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements. Substitute parts must maintain identical electrical specifications, package dimensions, and pin configurations to ensure direct compatibility.

Substitute Part Grouping Explanation

Substitution for the FIN1215MTD is determined by strict equivalence across the following critical parameters: data rate (1.785 Gbps), input/output configuration (21 LVTTL inputs to 3 LVDS outputs), supply voltage range (3V–3.6V), operating temperature range (-40°C to 85°C), and physical package (48-TFSOP). Parts are grouped into two categories:

Direct Substitute (Packaging Variant): FIN1215MTDX maintains identical electrical and functional specifications as the main part, with the only difference being packaging format (Tape & Reel versus bulk).

Functional Equivalent (Cross-Manufacturer): DS90CR217MTDX/NOPB from Texas Instruments provides equivalent serializer functionality with matching package and supply specifications, though detailed input/output configuration data is not provided in the source documentation.

Engineering Selection Recommendations

FIN1215MTDX is the primary substitute for FIN1215MTD. Both parts are manufactured by onsemi with identical electrical specifications and package dimensions. FIN1215MTDX carries Active product status and ROHS3 compliance, making it suitable for new designs and production environments requiring regulatory adherence. The packaging difference (Tape & Reel format) does not affect electrical performance or pin compatibility.

DS90CR217MTDX/NOPB from Texas Instruments is a functional equivalent based on matching package type and supply voltage specifications. However, complete electrical parameter documentation for this part is not available in the provided source data. Selection of this part requires independent verification of input/output configuration, data rate, and signal type compatibility with the original FIN1215MTD application.

Frequently Asked Questions (FAQ)

Q: Can FIN1215MTDX be used as a direct replacement for FIN1215MTD?

A: Yes. FIN1215MTDX maintains identical electrical specifications, pin configuration, and package dimensions. The only difference is packaging format (Tape & Reel). Both parts are manufactured by onsemi and are electrically interchangeable.

Q: Why is FIN1215MTD classified as obsolete?

A: Product status reflects manufacturer lifecycle decisions. FIN1215MTDX, the active variant, is available as a direct substitute with equivalent performance.

Q: What are the key parameters that determine substitutability?

A: Critical parameters are data rate (1.785 Gbps), input/output configuration (21 LVTTL to 3 LVDS), supply voltage (3V–3.6V), operating temperature range (-40°C to 85°C), and package type (48-TFSOP). Any deviation in these parameters affects compatibility.

Q: Is DS90CR217MTDX/NOPB a suitable replacement?

A: DS90CR217MTDX/NOPB shares the same package and supply voltage specifications. However, detailed input/output configuration and data rate specifications are not provided in available documentation. Functional equivalence must be independently confirmed before selection.

Q: What is the difference between MSL ratings of the parts?

A: FIN1215MTD has MSL 1 (Unlimited moisture sensitivity), while FIN1215MTDX and DS90CR217MTDX/NOPB have MSL 2 (1 Year). MSL 2 requires controlled storage conditions and handling within one year of manufacture. This affects supply chain and storage requirements but not electrical performance.

Q: Are both substitute parts RoHS compliant?

A: Yes. FIN1215MTDX and DS90CR217MTDX/NOPB are both ROHS3 compliant. RoHS compliance status for FIN1215MTD is not specified in available documentation.
