Molex 0955022883 Equivalent & Substitute Parts

Part Overview

The Molex 0955022883 is a modular jack connector (8P8C/RJ45) designed for Ethernet applications with vertical through-hole mounting and unshielded Cat3 rating. This connector features board lock functionality, phosphor bronze contacts with gold finish, and operates across -40°C to 80°C. The part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications requiring this connector type.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the Molex 0955022883 is determined by strict equivalence across the following critical parameters:

• Connector type: Jack modular connector
• Contact configuration: 8P8C (RJ45/Ethernet standard)
• Mounting method: Through hole solder termination
• Physical orientation: Vertical
• Electrical rating: Cat3 unshielded
• Mechanical features: Board lock with user-selectable tab direction
• Contact material and finish: Phosphor bronze with gold plating (50.0µin minimum)
• Moisture sensitivity: MSL 1 (unlimited shelf life)

The two substitute parts listed (TE Connectivity 5556416-1 and 5569284-1) meet all these criteria. Both are active products from a major connector manufacturer, providing direct functional and mechanical compatibility with the obsolete Molex part.

Parameter Comparison

Engineering Selection Recommendations

Both TE Connectivity substitutes provide direct functional equivalence to the obsolete Molex 0955022883 across all critical electrical and mechanical parameters. Selection between the two active alternatives depends on specific application requirements:

TE Connectivity 5556416-1 features PBT/Polyester housing material and maintains REACH Unaffected status, providing full regulatory clarity for international applications. This part is recommended for applications requiring explicit REACH compliance documentation.

TE Connectivity 5569284-1 features Polyamide (PA/Nylon) housing material with vendor-undefined REACH status. This part offers equivalent electrical and mechanical performance with a slightly different material composition. Clarification of REACH applicability may be required for regulated markets.

Both substitutes operate across -40°C to 85°C, providing a 5°C extended upper temperature range compared to the original Molex part. Both maintain RoHS compliance, MSL 1 rating, and identical contact specifications (phosphor bronze with 50.0µin gold finish).

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity 5556416-1 and 5569284-1 be used interchangeably with Molex 0955022883?

A: Both TE Connectivity parts are functionally equivalent substitutes. They share identical connector type, contact configuration (8P8C), mounting method (through-hole vertical solder), electrical rating (Cat3 unshielded), and mechanical features (board lock, user-selectable tab). The primary difference is housing material composition (PBT/Polyester vs. Polyamide/Nylon), which does not affect electrical or mechanical compatibility for standard applications.

Q: What is the difference in operating temperature range?

A: The Molex 0955022883 operates from -40°C to 80°C. Both TE Connectivity substitutes extend the upper limit to 85°C. For applications operating within the original -40°C to 80°C range, both substitutes are fully compatible. Applications requiring operation above 80°C benefit from the extended range of the TE Connectivity parts.

Q: Are there packaging differences between the substitutes?

A: The Molex 0955022883 packaging is not specified in the available data. Both TE Connectivity substitutes are supplied in Tray packaging. Confirm tray specifications match your assembly process requirements.

Q: What is the significance of the housing material difference?

A: The Molex part uses generic thermoplastic housing. TE Connectivity 5556416-1 specifies PBT/Polyester, and 5569284-1 specifies Polyamide/Nylon. Both materials are standard for modular connector housings and provide equivalent mechanical performance for this connector class. Material selection may be relevant for specific environmental or chemical exposure conditions.

Q: Are both substitutes RoHS compliant?

A: Yes. The Molex 0955022883 is ROHS3 Compliant. Both TE Connectivity substitutes are RoHS Compliant. All three parts meet RoHS requirements for lead-free solder and restricted substance limits.

Q: What is the REACH compliance status for each part?

A: Molex 0955022883 and TE Connectivity 5556416-1 are both REACH Unaffected. TE Connectivity 5569284-1 has Vendor Undefined REACH status. For applications in regulated markets requiring explicit REACH compliance documentation, 5556416-1 is the preferred substitute.

Q: Do the substitutes maintain the same contact finish specification?

A: Yes. All three parts use phosphor bronze contacts with gold finish at 50.0µin (1.27µm) thickness, ensuring equivalent electrical performance and contact reliability.
