UAA2016D Equivalent & Substitute Parts

Part Overview

The UAA2016D is a Power Management Integrated Circuit (PMIC) designed for electric heating systems applications. It functions as a zero voltage switch power controller in an 8-SOIC surface mount package. The UAA2016D is classified as obsolete, which necessitates identification of active equivalent parts to maintain design continuity and ensure long-term component availability for production and field service applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the UAA2016D is determined by strict equivalence across the following critical parameters:

• Functional Classification: Power Management PMIC with zero voltage switch controller functionality
• Package Type: 8-SOIC surface mount package with identical 0.154" (3.90mm) width specification
• Electrical Specifications: Supply current of 900µA and supply voltage range of -10V to -8V
• Operating Temperature Range: -20°C to 85°C
• Application Domain: Electric heating systems

The UAA2016DG qualifies as a direct substitute based on identical electrical ratings, package configuration, and functional purpose. The primary distinction between the main part and substitute is product status and compliance certification level.

Parameter Comparison

Engineering Selection Recommendations

The UAA2016DG is the direct equivalent substitute for the obsolete UAA2016D. Both parts share identical electrical specifications, package configuration, and functional characteristics required for electric heating systems applications.

The UAA2016DG offers the following advantages for new designs and component replacement:

• Active Product Status: The UAA2016DG maintains active production status, ensuring continued availability and supply chain reliability.
• Enhanced Compliance: The UAA2016DG meets ROHS3 compliance requirements, whereas the UAA2016D is non-compliant.
• Improved Moisture Handling: The UAA2016DG features MSL 1 (Unlimited) rating compared to MSL 3 (168 Hours) for the UAA2016D, reducing moisture-related handling constraints during manufacturing and storage.
• Regulatory Alignment: Both parts maintain identical REACH Unaffected and EAR99 ECCN classifications.

For applications currently using UAA2016D, direct substitution with UAA2016DG is electrically and mechanically compatible without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can UAA2016DG be used as a direct replacement for UAA2016D in existing designs?

A: Yes. The UAA2016DG is electrically and mechanically equivalent to the UAA2016D. Both parts feature identical supply current (900µA), supply voltage range (-10V to -8V), operating temperature range (-20°C to 85°C), and 8-SOIC package configuration. No circuit modifications are required.

Q: What is the primary reason for substituting UAA2016D with UAA2016DG?

A: The UAA2016D is classified as obsolete, creating supply and long-term availability risks. The UAA2016DG is an active product from the same manufacturer with identical electrical and mechanical specifications, ensuring continued component availability.

Q: Are there packaging differences between UAA2016D and UAA2016DG?

A: Both parts use the same 8-SOIC (0.154", 3.90mm Width) surface mount package. The UAA2016DG is supplied in Tube packaging, while the UAA2016D packaging specification was not provided. The package footprint and pin configuration are identical.

Q: Does the UAA2016DG meet modern compliance standards?

A: The UAA2016DG is ROHS3 compliant, whereas the UAA2016D is non-compliant. Both parts maintain REACH Unaffected status and EAR99 ECCN classification. The UAA2016DG also features improved moisture sensitivity level (MSL 1 Unlimited versus MSL 3 168 Hours).

Q: Are there any electrical performance differences between the two parts?

A: No. Both parts are specified with identical electrical parameters: 900µA supply current, -10V to -8V supply voltage range, and -20°C to 85°C operating temperature range. They are functionally equivalent for electric heating systems applications.
