Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 390322-1 are identified based on strict equivalence across critical electrical and mechanical parameters. The substitution logic requires that alternative parts maintain:

Critical Parameters (Must Match Exactly):

• Connector style: SODIMM format
• Position count: 144 positions
• Memory type: SDRAM compatibility
• Mounting method: Surface mount technology
• Insertion angle: Right angle configuration
• Card thickness accommodation: 0.050" (1.27mm)

Important Parameters (Must Match or Exceed):

• Contact finish: Gold plating
• Mounting feature: Normal, standard top-side mounting
• RoHS compliance: RoHS3 or equivalent
• Moisture sensitivity: MSL 1 or better

The TE Connectivity 390112-1 qualifies as a direct substitute based on full alignment with all critical parameters and equivalent or superior compliance ratings.

Engineering Selection Recommendations

The TE Connectivity 390112-1 is the qualified substitute for the obsolete 390322-1 connector. Selection of the 390112-1 is based on the following engineering criteria:

Electrical Compatibility: Both connectors maintain identical contact finish specifications (gold plating at 10.0µin thickness) and support the same SDRAM memory type with 144-position configuration, ensuring full electrical interchangeability.

Mechanical Compatibility: Both connectors accommodate the same card thickness (0.050" / 1.27mm), feature identical mounting methods (surface mount, right angle, top-side standard mounting), and include board guides and latches for equivalent mechanical retention.

Compliance Status: The 390112-1 carries ROHS3 compliance, which exceeds the RoHS compliance of the obsolete 390322-1. Both parts maintain MSL 1 rating and identical export classification (EAR99).

Product Availability: The 390112-1 is classified as active with current inventory availability, whereas the 390322-1 is obsolete. This status difference necessitates transition to the substitute part for ongoing production and new design implementations.

Height Consideration: The 390112-1 features a reduced height of 0.220" (5.60mm) compared to the 390322-1 at 0.390" (9.90mm). This dimensional difference does not affect electrical or functional compatibility but may provide design benefits in space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can the 390112-1 directly replace the 390322-1 in existing designs?

A: Yes. The 390112-1 maintains identical electrical and mechanical specifications across all critical parameters including connector style, position count, memory type, mounting method, insertion angle, and card thickness accommodation. The parts are functionally interchangeable.

Q: What is the significance of the height difference between these connectors?

A: The 390112-1 has a reduced height of 0.220" (5.60mm) versus the 390322-1 at 0.390" (9.90mm). This dimensional difference does not affect electrical performance or functional compatibility. The reduced height may provide advantages in applications with vertical space constraints on the printed circuit board.

Q: Are there any compliance differences between the two parts?

A: The 390112-1 carries ROHS3 compliance, which represents current regulatory standards and exceeds the RoHS compliance of the obsolete 390322-1. Both parts maintain identical MSL 1 ratings and export classifications. The 390112-1 is the preferred choice for new designs requiring current compliance certifications.

Q: What packaging differences exist between these parts?

A: The 390322-1 is supplied without specified packaging notation, while the 390112-1 is supplied in tray packaging. Tray packaging is standard for surface mount connectors and facilitates automated assembly processes.

Q: Why is the 390322-1 classified as obsolete?

A: The 390322-1 has been discontinued by TE Connectivity. The 390112-1 represents the active equivalent product line, offering identical functionality with current manufacturing and compliance standards. Transition to the 390112-1 is necessary for ongoing production support and component availability.

Q: Are the contact finish specifications identical?

A: Yes. Both connectors feature gold contact finish at 10.0µin (0.25µm) thickness, ensuring equivalent electrical performance and corrosion resistance characteristics.

Q: Can the 390112-1 be used in new product designs?

A: Yes. The 390112-1 is classified as active with current inventory availability. It is the appropriate choice for new designs requiring a 144-position SODIMM SDRAM socket connector with surface mount configuration and right-angle insertion.
