ISO1211DR Equivalent & Substitute Parts

Part Overview

The ISO1211DR is a specialized interface integrated circuit manufactured by Texas Instruments, classified as a PLC Digital Input Modules Interface component. This 8-SOIC surface mount device operates within a supply voltage range of 2.25V to 5.5V and is designed for digital interface applications in industrial control systems. The part maintains Active product status with ROHS3 compliance and carries an MSL rating of 2 (1 Year). Substitute parts are identified when equivalent functional performance can be achieved within the specified electrical and mechanical parameters while maintaining compatibility with the target application environment.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ISO1211DR are identified based on the following critical parameters:

• Package Compatibility: Surface mount packages with equivalent or compatible footprints
• Voltage Supply Range: Operating voltage specifications that encompass or align with the 2.25V ~ 5.5V requirement
• Functional Classification: Digital interface components serving equivalent PLC and industrial control applications
• Compliance Status: ROHS3 compliance and REACH unaffected status maintained across substitutes
• Product Status: Active manufacturing status ensuring availability and long-term support

The identified substitutes SI8710CD-B-ISR and SI8719BC-A-IS are digital isolator components from Skyworks Solutions Inc. that provide equivalent interface functionality for PLC digital input module applications. SI8719BC-A-IS maintains the identical 8-SOIC package footprint as the ISO1211DR, while SI8710CD-B-ISR operates in a 6-SOIC package configuration.

Parameter Comparison

Engineering Selection Recommendations

Selection between the ISO1211DR and its substitutes is determined by package footprint requirements and supply voltage specifications:

SI8719BC-A-IS is the primary substitute candidate, maintaining identical 8-SOIC package dimensions (0.154", 3.90mm Width) and compatible supply voltage range (2.5V ~ 5.5V overlaps with 2.25V ~ 5.5V). This part preserves PCB layout compatibility and mounting requirements while maintaining Active product status and ROHS3 compliance.

SI8710CD-B-ISR serves as an alternative for applications where package footprint flexibility exists. The 6-SOIC package (0.295", 7.50mm Width) represents a different form factor requiring PCB redesign. The extended supply voltage range (3V ~ 30V) accommodates broader system requirements. This substitute maintains Active status and ROHS3 compliance.

Both substitutes maintain REACH unaffected status consistent with the original part. All three components are currently in active production with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can SI8719BC-A-IS directly replace ISO1211DR without PCB modification?

A: SI8719BC-A-IS maintains the identical 8-SOIC package footprint (0.154", 3.90mm Width), enabling direct PCB placement compatibility. Supply voltage specifications (2.5V ~ 5.5V) overlap with the ISO1211DR requirement (2.25V ~ 5.5V), supporting functional substitution in standard PLC digital input module applications.

Q: What are the package differences between the substitute options?

A: SI8719BC-A-IS uses an 8-SOIC package matching the ISO1211DR footprint. SI8710CD-B-ISR employs a 6-SOIC package with larger dimensions (0.295", 7.50mm Width versus 0.154", 3.90mm Width), requiring PCB layout modifications for implementation.

Q: Are all parts ROHS3 compliant?

A: Yes. ISO1211DR, SI8710CD-B-ISR, and SI8719BC-A-IS all maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements.

Q: What supply voltage considerations apply to substitution?

A: The ISO1211DR operates at 2.25V ~ 5.5V. SI8719BC-A-IS operates at 2.5V ~ 5.5V, covering the primary operating range. SI8710CD-B-ISR operates at 3V ~ 30V, providing extended voltage capability for systems requiring broader supply specifications.

Q: Are moisture sensitivity levels comparable across parts?

A: ISO1211DR carries MSL 2 (1 Year). SI8710CD-B-ISR and SI8719BC-A-IS both carry MSL 3 (168 Hours), indicating different moisture exposure handling requirements during storage and assembly processes.
