Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1658390-1 is based on the following critical parameters that must align between the main part and substitute candidates:

Mandatory Matching Parameters:

• Number of Positions: 160 (20 x 8)
• Connector Style: Receptacle with Cage, Ganged (2x4)
• Mounting Type: Through Hole, Right Angle
• Features: Board Guide, EMI Shielded
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variations:

• Connector Type: SFP to SFP+ (backward compatible protocol evolution)
• Termination Type: Solder to Press-Fit (both through-hole termination methods)
• Contact Finish and Finish Thickness: Variations permitted based on application requirements
• Packaging: Different packaging formats acceptable for equivalent functionality

The Molex 0760465001 meets all mandatory matching parameters while introducing SFP+ protocol capability and press-fit termination, making it a functional substitute for the obsolete 1658390-1.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement of Obsolete 1658390-1:

The Molex 0760465001 serves as the primary substitute for the obsolete TE Connectivity 1658390-1. Both connectors maintain identical physical form factors, position counts, and mounting configurations. The 0760465001 is currently in active production status, ensuring long-term supply chain availability.

Compliance Considerations:

Both the main part and substitute are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement. Moisture sensitivity levels are identical at MSL 1 (Unlimited), indicating no special storage or handling requirements.

Termination Method Transition:

The primary difference between these connectors is the termination method: the 1658390-1 uses solder termination while the 0760465001 uses press-fit termination. Press-fit termination offers advantages in manufacturing efficiency and eliminates thermal stress associated with solder reflow processes. PCB design modifications are required to accommodate press-fit contact holes, which differ from solder through-hole specifications.

Protocol Enhancement:

The 0760465001 supports SFP+ protocol, which is backward compatible with SFP applications. This upgrade path provides enhanced signal integrity and future-proofing for systems requiring higher data rates.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0760465001 directly replace the TE Connectivity 1658390-1 without PCB modifications?

A: The connectors share identical external dimensions, mounting footprints, and position configurations. However, the termination method differs: the 1658390-1 requires solder through-holes while the 0760465001 requires press-fit contact holes. PCB redesign is necessary to accommodate the different termination specifications.

Q: What is the difference between SFP and SFP+ connector types?

A: SFP+ is an enhanced version of the SFP standard supporting higher data rates. The 0760465001 SFP+ receptacle is backward compatible with SFP modules, making it suitable for both legacy and next-generation applications.

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

A: Both connectors are ROHS3 compliant and REACH unaffected. Moisture sensitivity levels are identical at MSL 1 (Unlimited). No special handling or storage requirements differentiate these parts from a compliance perspective.

Q: What advantages does press-fit termination offer over solder termination?

A: Press-fit termination eliminates thermal stress from solder reflow, reduces manufacturing process complexity, and improves contact reliability. The termination method selection depends on manufacturing capabilities and PCB design specifications.

Q: Does the Molex 0760465001 include additional features compared to the 1658390-1?

A: The 0760465001 includes a light pipe feature in addition to the board guide and EMI shielding present in the 1658390-1. The light pipe provides visual indication of connector status or signal presence.

Q: What is the contact finish specification for the 1658390-1?

A: Contact finish specifications are not provided for the 1658390-1. The Molex 0760465001 specifies gold plating at 30.0µin (0.76µm) thickness, which is standard for high-reliability SFP+ applications.

Q: Are both connectors available in the same packaging format?

A: The 1658390-1 packaging is not specified. The 0760465001 is supplied in tray packaging. Packaging format selection depends on production volume and handling requirements.
