FHP3194IM14X Equivalent & Substitute Parts

Part Overview

The FHP3194IM14X is a video switch IC manufactured by onsemi, configured as a 4:1 multiplexer in a 14-SOIC package. This component is classified as obsolete, making equivalent substitutes necessary for new designs and production continuity. The part operates across a wide supply voltage range (5V ~ 12V single supply, or ±2.5V ~ 6V dual supply) with an -3dB bandwidth of 800MHz, supporting video switching applications with shutdown and disable features.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the FHP3194IM14X is determined by the following critical parameters:

• Package Compatibility: 14-SOIC form factor (0.154", 3.90mm Width) — identical physical footprint required for direct PCB replacement
• Supply Voltage Range: Dual supply operation (±4.6V ~ 6V minimum) — must accommodate the design's power distribution architecture
• Functional Category: Interface multiplexer with amplifier capability — supports video switching and signal routing applications
• Mounting Type: Surface mount — consistent with modern assembly processes
• Product Status: Active alternatives required — obsolete status necessitates transition to in-production components

The substitute parts OPA4872ID and OPA4872MDREP meet these criteria as Texas Instruments interface multiplexer components in identical 14-SOIC packaging with active product status and ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

OPA4872ID is suitable for applications requiring tube packaging with lower inventory volumes. This variant maintains active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment.

OPA4872MDREP is the preferred selection for production environments. The tape and reel packaging format supports automated assembly processes, with significantly higher inventory availability (2217 pcs) compared to the tube variant. Both OPA4872 variants provide ROHS3 compliance and REACH compliance, meeting modern environmental and regulatory requirements.

The transition from the obsolete FHP3194IM14X to either OPA4872 variant eliminates supply chain risk while maintaining functional equivalence within the specified electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can OPA4872ID and OPA4872MDREP be used interchangeably with FHP3194IM14X?

A: Yes, both variants are electrically and mechanically equivalent. The difference lies in packaging format: OPA4872ID uses tube packaging, while OPA4872MDREP uses tape and reel. Selection depends on assembly method and inventory requirements.

Q: What is the primary reason for substitution?

A: The FHP3194IM14X is classified as obsolete. The OPA4872 series provides active, in-production alternatives with identical 14-SOIC packaging and compatible electrical specifications.

Q: Are there supply voltage compatibility concerns?

A: The OPA4872 series operates at ±4.6V ~ 6V dual supply, compared to the FHP3194IM14X range of ±2.5V ~ 6V. Designs operating below ±4.6V require verification of circuit performance with the substitute part.

Q: What packaging considerations apply?

A: Both substitutes use 14-SOIC (0.154", 3.90mm Width) surface mount packages, identical to the original part. No PCB layout modifications are required for direct replacement.

Q: Do the substitutes meet current compliance standards?

A: Yes. Both OPA4872 variants are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The original FHP3194IM14X compliance status is not specified.

Q: What is the moisture sensitivity difference?

A: The FHP3194IM14X has MSL 1 (unlimited shelf life), while OPA4872 variants have MSL 2 (1-year shelf life). This requires standard moisture control procedures during storage and handling for the substitute parts.
