PE64904C-Z Equivalent & Substitute Parts

Part Overview

The PE64904C-Z is an RF IC Digitally Tunable Capacitor manufactured by pSemi, designed for general-purpose RF applications across the 100MHz to 3GHz frequency range. This component features an SPI interface and is packaged in a 10-QFN (2x2) surface-mount configuration. The PE64904C-Z is currently discontinued at DiGi Electronics, making identification of suitable equivalent parts essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PE64904C-Z is determined by the following critical parameters:

• Functional equivalence: Digitally Tunable Capacitor with identical RF application scope
• Frequency compatibility: 100MHz ~ 3GHz operating range
• Interface compatibility: SPI control interface
• Package compatibility: 10-QFN (2x2) surface-mount form factor
• Electrical specifications: Supply voltage and control characteristics
• Compliance standards: RoHS and REACH certification status

The PE64904D-Z meets all substitution criteria as a direct equivalent part from the same manufacturer, with identical functional specifications and package configuration.

Parameter Comparison

Engineering Selection Recommendations

The PE64904D-Z is the direct substitute for the discontinued PE64904C-Z. Both parts are manufactured by pSemi and share identical functional specifications, frequency range, interface protocol, and package configuration. The PE64904D-Z is currently in active production status with confirmed inventory availability.

The primary distinction between these parts is packaging format: the PE64904C-Z was supplied in Cut Tape and Digi-Reel formats, while the PE64904D-Z is supplied in Tape & Reel format. This difference does not affect electrical or mechanical compatibility and is a standard variation in component distribution.

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), ensuring equivalent reliability and handling requirements. The PE64904D-Z includes specified supply voltage parameters (2.3V ~ 3.6V), providing additional design documentation clarity compared to the original part specification.

Frequently Asked Questions (FAQ)

Q: Can the PE64904D-Z directly replace the PE64904C-Z in existing designs?

A: Yes. The PE64904D-Z is electrically and mechanically equivalent to the PE64904C-Z. Both parts feature identical frequency range (100MHz ~ 3GHz), SPI interface, 10-QFN (2x2) package, and general-purpose RF application scope. No design modifications are required.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) and Digi-Reel packaging are used for lower-volume orders and manual handling, while Tape & Reel (TR) packaging is standard for automated assembly processes. The electrical and mechanical specifications of the component remain identical regardless of packaging format.

Q: Are there any compliance or certification differences between these parts?

A: Both the PE64904C-Z and PE64904D-Z maintain ROHS3 compliance and identical moisture sensitivity levels (MSL 1). No compliance or certification differences exist between these parts.

Q: Why is the PE64904D-Z listed as active while the PE64904C-Z is discontinued?

A: The PE64904C-Z has been discontinued at DiGi Electronics as part of normal product lifecycle management. The PE64904D-Z represents the current active equivalent from pSemi and is the recommended part for new designs and production continuity.

Q: Is the supply voltage specification (2.3V ~ 3.6V) on the PE64904D-Z a functional difference?

A: No. The supply voltage specification on the PE64904D-Z provides explicit documentation of operating parameters. This represents improved specification clarity rather than a functional change from the PE64904C-Z.
