OPA4872IDG4 Equivalent & Substitute Parts

Part Overview

The OPA4872IDG4 is a specialized interface integrated circuit designed for multiplexer with amplifier applications. Manufactured by Texas Instruments, this component is packaged in a 14-SOIC form factor and operates within a ±4.6V to 6V supply voltage range. The OPA4872IDG4 is currently discontinued at DiGi Electronics, making identification of equivalent and substitute parts essential for ongoing design support and production continuity. Substitute components must maintain functional compatibility while meeting the same electrical specifications and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the OPA4872IDG4 are identified based on the following critical parameters:

Primary Substitution Criteria:

• Functional category: Interface (specialized)
• Application compatibility: Multiplexer with Amplifier functionality
• Supply voltage range: ±4.6V ~ 6V
• Mounting type: Surface Mount
• Compliance standards: ROHS3 Compliant, REACH Unaffected

Package Consideration: The OPA4872IDG4 is available in 14-SOIC packaging. Substitute parts may utilize alternative surface-mount packages provided they maintain electrical and functional equivalence. Package differences require PCB layout evaluation during design integration.

Two substitute parts are identified: the OPA4872ID (same base product, alternative packaging) and the PI3HDX1204B1ZHIEX (functionally equivalent interface component with different package form factor).

Parameter Comparison

Engineering Selection Recommendations

OPA4872ID (Manufacturer Recommended Substitute): The OPA4872ID is the primary substitute for the OPA4872IDG4. Both components share identical electrical specifications, functional characteristics, and package form factor. The OPA4872ID maintains active product status with current inventory availability. This substitute requires no design modifications and provides direct functional replacement. Compliance certifications (ROHS3, REACH Unaffected) are equivalent.

PI3HDX1204B1ZHIEX (Alternative Interface Solution): The PI3HDX1204B1ZHIEX is a functionally equivalent interface component from Diodes Incorporated. While it operates within a narrower supply voltage range (3V ~ 3.6V) compared to the original specification (±4.6V ~ 6V), it maintains interface category classification and surface-mount deployment. The component utilizes a 42-VFQFN package, requiring PCB layout redesign. This substitute is suitable only when supply voltage requirements align with the 3V ~ 3.6V specification. Compliance status is equivalent (ROHS3 Compliant, REACH Unaffected).

Frequently Asked Questions (FAQ)

Q: Can the OPA4872ID be used as a direct replacement for the OPA4872IDG4? A: Yes. The OPA4872ID is electrically and functionally identical to the OPA4872IDG4. Both components operate at ±4.6V ~ 6V, utilize 14-SOIC packaging, and maintain equivalent compliance certifications. No design modifications are required.

Q: What is the difference between OPA4872IDG4 and OPA4872ID? A: The primary difference is packaging format. The OPA4872IDG4 is supplied in standard packaging, while the OPA4872ID is supplied in tube packaging. Electrical specifications and functional performance are identical.

Q: Is the PI3HDX1204B1ZHIEX suitable for all OPA4872IDG4 applications? A: The PI3HDX1204B1ZHIEX is functionally equivalent but operates at a reduced supply voltage range (3V ~ 3.6V). It is suitable only for applications where the supply voltage requirement does not exceed 3.6V. Additionally, the 42-VFQFN package requires PCB layout redesign compared to the 14-SOIC form factor.

Q: Are all substitute parts ROHS3 compliant? A: Yes. Both the OPA4872ID and PI3HDX1204B1ZHIEX maintain ROHS3 compliance and REACH Unaffected status, matching the original OPA4872IDG4 specifications.

Q: What is the moisture sensitivity level difference between substitutes? A: The OPA4872ID maintains MSL 2 (1 Year) equivalent to the original part. The PI3HDX1204B1ZHIEX has improved moisture sensitivity at MSL 1 (Unlimited), providing enhanced storage and handling flexibility.

Q: Which substitute should be selected for new designs? A: The OPA4872ID is recommended for direct replacement applications. The PI3HDX1204B1ZHIEX should be selected only when supply voltage specifications align with the 3V ~ 3.6V range and package redesign is acceptable.
