LOC211P Equivalent & Substitute Parts

Part Overview

The LOC211P is a photovoltaic optoisolator manufactured by IXYS Integrated Circuits Division, featuring 3750Vrms isolation voltage across 2 channels with linearized output. This component is classified as obsolete, making equivalent substitutes necessary for ongoing system support and new design implementations. The part operates across the industrial temperature range of -40°C to 85°C and is packaged in a 16-SOIC surface mount configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LOC211P is determined by the following critical parameters:

• Voltage - Isolation: 3750Vrms isolation voltage is the primary electrical requirement
• Output Type: Photovoltaic, linearized output functionality
• Input Type: DC input operation
• Mounting Type: Surface mount configuration
• RoHS Compliance: ROHS3 Compliant status for regulatory alignment

The LOC111P qualifies as a manufacturer-recommended substitute based on matching isolation voltage (3750Vrms), output type (photovoltaic, linearized), input type (DC), and RoHS compliance. However, the LOC111P differs in channel configuration (1 channel versus 2 channels) and package type (8-Flatpack versus 16-SOIC). These differences require evaluation based on specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The LOC111P is an active product from the same manufacturer with identical isolation voltage and output type specifications. Selection between the main part and substitute depends on application-specific requirements:

Channel Configuration: The LOC211P provides 2 isolated channels in a single package, while the LOC111P provides 1 channel. Applications requiring dual-channel isolation in a single component cannot be directly replaced by the LOC111P without circuit redesign.

Package Compatibility: The LOC211P uses a 16-SOIC package while the LOC111P uses an 8-Flatpack package. PCB layout and footprint modifications are required for substitution.

Product Status: The LOC111P is active and supported by the manufacturer, whereas the LOC211P is obsolete. For new designs or long-term supply assurance, the LOC111P is the preferred choice when channel and package requirements align.

Compliance: Both parts maintain ROHS3 compliance and EAR99 ECCN classification. The LOC111P has a higher moisture sensitivity level (MSL 3 versus MSL 1), requiring appropriate handling and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the LOC111P directly replace the LOC211P in existing designs?

A: Direct replacement is not possible without circuit modification. The LOC111P provides 1 channel versus the LOC211P's 2 channels, and uses a different package (8-Flatpack versus 16-SOIC). PCB redesign and circuit reconfiguration are required.

Q: What is the primary reason for substitution?

A: The LOC211P is obsolete. The LOC111P is the manufacturer-recommended substitute offering the same isolation voltage and photovoltaic linearized output type from an active product line.

Q: Are there compliance differences between these parts?

A: Both parts are ROHS3 compliant and carry EAR99 ECCN classification. The LOC111P has a higher moisture sensitivity level (MSL 3 requiring 168-hour storage limits) compared to the LOC211P (MSL 1 with unlimited storage).

Q: What parameters must match for substitution consideration?

A: Critical matching parameters are isolation voltage (3750Vrms), output type (photovoltaic, linearized), input type (DC), and mounting type (surface mount). Channel count and package type are application-dependent considerations.

Q: Is the LOC111P suitable for the same temperature range?

A: The LOC211P specifies -40°C to 85°C operating temperature. The LOC111P operating temperature is not specified in the provided data and must be verified against the component datasheet for temperature-critical applications.
