Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PI2PCIE412-DZHEX is determined by the following critical parameters:

• Package Compatibility: Identical 42-TQFN (9x4.6) surface mount package with 42-VFQFN Exposed Pad configuration
• Functional Equivalence: 4-channel PCI Express® multiplexer/demultiplexer circuit with 2:1 switching capability
• Electrical Specifications: Supply voltage range, operating temperature range, and bandwidth performance
• Compliance Standards: RoHS3 compliance, MSL rating, and regulatory certifications (REACH, ECCN, HTSUS)

The PI2PCIE2412ZHEX meets all substitution criteria as a manufacturer-recommended equivalent from Diodes Incorporated, maintaining identical package geometry, channel configuration, and functional architecture while offering enhanced bandwidth performance and improved product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

The PI2PCIE2412ZHEX is the manufacturer-recommended substitute for the obsolete PI2PCIE412-DZHEX. Both components maintain identical mechanical compatibility, functional architecture, and regulatory compliance certifications.

The PI2PCIE2412ZHEX offers extended product lifecycle status (Last Time Buy versus Obsolete), ensuring greater availability for procurement and production planning. Both parts carry ROHS3 compliance, REACH Unaffected status, and identical regulatory classifications (EAR99, HTSUS 8542.39.0001).

The PI2PCIE2412ZHEX demonstrates superior bandwidth performance (4.1 GHz versus 1.4 GHz) and operates within a narrower supply voltage range (1.5V ~ 1.8V versus 1.5V ~ 2V). These electrical differences do not preclude substitution when the design supply voltage falls within the PI2PCIE2412ZHEX operating range.

Frequently Asked Questions (FAQ)

Q: Can the PI2PCIE2412ZHEX directly replace the PI2PCIE412-DZHEX in existing designs?

A: Yes, provided the design supply voltage operates within the PI2PCIE2412ZHEX range of 1.5V ~ 1.8V. The components share identical package geometry (42-TQFN 9x4.6), pin configuration, and functional specifications for 4-channel PCI Express® multiplexing/demultiplexing.

Q: What are the key differences between these two parts?

A: The primary differences are product lifecycle status and electrical performance. The PI2PCIE2412ZHEX operates at higher bandwidth (4.1 GHz versus 1.4 GHz) and requires a narrower supply voltage range (1.5V ~ 1.8V versus 1.5V ~ 2V).

Q: Are there packaging differences between the PI2PCIE412-DZHEX and PI2PCIE2412ZHEX?

A: No. Both components use identical 42-TQFN (9x4.6) surface mount packages with 42-VFQFN Exposed Pad configuration. The PI2PCIE2412ZHEX is supplied in Tape & Reel (TR) packaging format.

Q: Do both parts meet the same compliance and regulatory requirements?

A: Yes. Both the PI2PCIE412-DZHEX and PI2PCIE2412ZHEX are ROHS3 compliant, REACH Unaffected, and classified under identical regulatory codes (EAR99, HTSUS 8542.39.0001). Both carry MSL rating of 1 (Unlimited).

Q: Why is the PI2PCIE412-DZHEX listed as Obsolete?

A: The Obsolete status indicates the manufacturer has discontinued production and support for this part number. The PI2PCIE2412ZHEX represents the current equivalent offering with extended product lifecycle support.
