Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PI3PCIE3412ZHEX is determined by strict equivalence across the following critical parameters:

• Multiplexer/Demultiplexer Circuit configuration (2:1)
• Number of channels (4)
• On-state resistance specification (5Ohm Typ)
• Supply voltage range (3V ~ 3.6V)
• Bandwidth performance (-3dB at 8.2GHz)
• Feature set (Bi-Directional, SATA, USB 3.0 support)
• Physical package (42-TQFN 9x4.6mm)
• Compliance certifications (ROHS3, REACH Unaffected)

The PI3PCIE3412AZHEX meets all substitution criteria as a direct equivalent, sharing identical electrical specifications and physical packaging while differing only in product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. standard packaging).

Parameter Comparison

Engineering Selection Recommendations

The PI3PCIE3412AZHEX is a direct functional equivalent to the PI3PCIE3412ZHEX. Both components maintain identical electrical performance specifications and physical form factors. The primary distinction is product lifecycle status: the original part is obsolete while the substitute remains in active production.

For new designs or component replenishment, the PI3PCIE3412AZHEX is the appropriate selection. Both parts carry equivalent compliance certifications (ROHS3 Compliant, REACH Unaffected) and identical moisture sensitivity ratings, ensuring compatibility with existing manufacturing and assembly processes.

The Tape & Reel packaging format of the substitute part is standard for high-volume production environments and does not affect electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can PI3PCIE3412AZHEX directly replace PI3PCIE3412ZHEX in existing designs?

A: Yes. Both parts share identical electrical specifications, channel configuration, bandwidth performance, supply voltage requirements, and physical packaging dimensions. No circuit modifications are required.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The original part is no longer manufactured. The substitute part remains in active production, ensuring long-term availability for procurement and support.

Q: Are there packaging compatibility concerns between the two part numbers?

A: No. Both components use the 42-TQFN (9x4.6mm) package with 42-VFQFN Exposed Pad configuration. The difference in packaging format (Tape & Reel vs. standard) relates only to supply method and does not affect PCB assembly or electrical performance.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both PI3PCIE3412ZHEX and PI3PCIE3412AZHEX are ROHS3 Compliant, REACH Unaffected, and carry identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited).

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

A: Substitution is based on matching 2:1 multiplexer/demultiplexer configuration, 4-channel architecture, 5Ohm typical on-state resistance, 3V to 3.6V supply voltage, 8.2GHz bandwidth, bi-directional switching with SATA and USB 3.0 support, and identical 42-TQFN physical packaging.
