Key Parameters

Substitute Part Grouping Explanation

Substitution of the FMS6141CSX is determined by the following critical parameters:

• Functional Category: Linear video driver IC
• Supply Voltage Range: 4.75V ~ 5.25V compatibility
• Application Domain: Consumer video filtering and driving
• Mounting Technology: Surface mount configuration
• Base Product Number: FMS6141 series designation

The FMS6141S5X qualifies as a functional substitute based on matching the base product number (FMS6141), identical supply voltage specification, equivalent driver function, and shared application in consumer video systems. Both parts operate within the same electrical parameters and serve identical functional roles despite differences in package form factor.

Parameter Comparison

Engineering Selection Recommendations

The FMS6141S5X is an active substitute for the obsolete FMS6141CSX. Both parts maintain identical electrical specifications including supply voltage range (4.75V ~ 5.25V), functional classification as video driver ICs, and application domain in consumer video systems. The FMS6141S5X carries RoHS3 compliance status, providing enhanced environmental and regulatory alignment compared to the obsolete original part.

The primary design consideration is package form factor: the FMS6141CSX uses an 8-SOIC package while the FMS6141S5X uses a 5-TSSOP (SC-70-5, SOT-353) package. PCB layout and footprint modifications are required for implementation of the substitute part.

Frequently Asked Questions (FAQ)

Q: Can the FMS6141S5X directly replace the FMS6141CSX without circuit modifications?

A: Electrical substitution is valid based on matching supply voltage, driver function, and consumer video application parameters. However, physical substitution requires PCB footprint redesign due to different package geometries (8-SOIC versus 5-TSSOP/SC-70-5).

Q: What is the significance of the FMS6141 base product number?

A: The FMS6141 base designation indicates the core video driver IC design. Variants such as FMS6141CSX and FMS6141S5X represent different package implementations of the same functional device, enabling substitution based on application requirements.

Q: Why is the FMS6141CSX classified as obsolete?

A: Obsolescence reflects the manufacturer's discontinuation of this specific part number. The FMS6141S5X remains in active production, making it the recommended path for new designs and legacy system support.

Q: Are there regulatory or compliance differences between these parts?

A: Both parts share identical REACH status (REACH Unaffected) and ECCN classification (EAR99). The FMS6141S5X includes RoHS3 compliance certification, providing additional environmental compliance assurance.

Q: What is the moisture sensitivity level (MSL) for the substitute part?

A: The FMS6141CSX specifies MSL 1 (Unlimited). The FMS6141S5X data was not provided with MSL information in the available parameters.
