AD8345ARE Equivalent & Substitute Parts

Part Overview

The AD8345ARE is an RF modulator integrated circuit designed for applications requiring frequency conversion in the 140MHz to 1GHz range. This device integrates modulation functionality within a compact 16-TSSOP surface mount package with exposed pad. The AD8345ARE is currently classified as obsolete, making identification of suitable substitute components essential for ongoing system support, design updates, and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AD8345ARE is determined by strict equivalence across the following critical parameters:

• Functional Classification: Modulator IC
• Frequency Operating Range: LO and RF frequency bands must match 140MHz ~ 1GHz
• Electrical Performance: P1dB, noise floor, output power, supply current, and supply voltage must be identical
• Package Specification: 16-TSSOP with exposed pad, surface mount configuration
• Thermal and Environmental Ratings: Moisture sensitivity level must be equivalent

The AD8345AREZ meets all substitution criteria as a direct equivalent part from the same manufacturer with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The AD8345AREZ is a direct functional and electrical equivalent to the AD8345ARE. Both parts share identical RF modulation specifications, frequency operating ranges, and package configurations. The primary distinction is product lifecycle status: the AD8345ARE is obsolete while the AD8345AREZ maintains active production status.

For new designs or system updates requiring RF modulation in the 140MHz to 1GHz band, the AD8345AREZ is the appropriate selection. For legacy system maintenance where the AD8345ARE is currently deployed, the AD8345AREZ provides pin-compatible and functionally equivalent replacement capability.

The AD8345AREZ carries RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement and deployment.

Frequently Asked Questions (FAQ)

Q: Can the AD8345AREZ directly replace the AD8345ARE in existing designs?

A: Yes. The AD8345AREZ is electrically and mechanically equivalent to the AD8345ARE. Both devices feature identical RF modulation performance, frequency ranges, supply specifications, and 16-TSSOP package configuration. Direct substitution is supported without circuit modification.

Q: What is the primary reason for substituting the AD8345ARE?

A: The AD8345ARE is classified as obsolete. The AD8345AREZ is the active production equivalent, ensuring continued component availability and supply chain reliability.

Q: Are there packaging differences between these parts?

A: The AD8345ARE is supplied in tape format, while the AD8345AREZ is supplied in tube packaging. Both use the identical 16-TSSOP (0.173", 4.40mm Width) exposed pad package. Packaging format does not affect electrical performance or PCB assembly compatibility.

Q: Do these parts have different compliance certifications?

A: The AD8345AREZ carries RoHS3 compliance and REACH unaffected status. Compliance documentation should be verified with the component supplier for the specific procurement lot.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution is determined by equivalence in function (modulator), frequency operating range (140MHz ~ 1GHz for both LO and RF), electrical performance metrics (P1dB, noise floor, output power, supply current and voltage), package type (16-TSSOP exposed pad), and moisture sensitivity rating (MSL 3).
