SS-39100-003 Equivalent & Substitute Parts

Part Overview

The SS-39100-003 is a modular connector plug manufactured by Stewart Connector, designed for 8-position 8-contact (8P8C) RJ45 Ethernet applications. This unshielded Cat6 connector features IDC (Insulation Displacement Contact) termination for round cable with solid or stranded wires. The part is currently classified as obsolete, necessitating identification of active equivalent alternatives to maintain supply chain continuity for applications requiring this connector type.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SS-39100-003 is determined by strict equivalence across the following critical parameters:

• Connector Type: Plug configuration
• Number of Positions/Contacts: 8P8C (RJ45, Ethernet) standard
• Cable Type: Round Cable, Solid or Stranded Wires compatibility
• Shielding: Unshielded construction
• Ratings: Cat6 performance category
• Termination: IDC contact system
• Length: 0.885" (22.48mm) physical dimension
• Color: Translucent - Clear appearance
• Contact Finish: Gold plating
• Contact Finish Thickness: 50.0µin (1.27µm)
• Current Rating: 1.5 A electrical specification
• Voltage Rating: 150V electrical specification
• Housing Material: Polycarbonate (PC)
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part SS-39100-021 maintains full equivalence across all specified parameters, with the exception of contact material composition (Copper Alloy versus Phosphor Bronze) and product status transition from obsolete to active.

Parameter Comparison

Engineering Selection Recommendations

The SS-39100-021 is the direct active equivalent for the obsolete SS-39100-003. Both parts are manufactured by Stewart Connector within the same Series 39 product line and maintain identical electrical and mechanical specifications across all critical parameters.

The transition from Phosphor Bronze to Copper Alloy contact material in the substitute part represents a material composition change within the same functional class. Both materials provide equivalent contact performance at the specified 1.5 A current rating and 150V voltage rating with gold plating at 50.0µin thickness.

The SS-39100-021 carries ROHS3 compliance certification, indicating adherence to current regulatory requirements. Both parts maintain REACH Unaffected status and MSL 1 (Unlimited) moisture sensitivity classification.

The substitute part is available in bulk packaging with significantly higher inventory levels (8475 Pcs versus 783 Pcs), supporting consistent supply chain availability for ongoing production requirements.

Frequently Asked Questions (FAQ)

Q: Can SS-39100-021 be used as a direct replacement for SS-39100-003 in existing designs?

A: Yes. The SS-39100-021 maintains full electrical and mechanical equivalence across all specified parameters including connector type, contact count, cable compatibility, shielding, ratings, termination method, physical dimensions, and electrical ratings.

Q: What is the difference between Phosphor Bronze and Copper Alloy contact materials?

A: Both materials are suitable for the specified 1.5 A current rating and 150V voltage rating with gold plating. The contact material composition does not affect functional compatibility in this application.

Q: Does the SS-39100-021 support the same cable types as the SS-39100-003?

A: Yes. Both parts are specified for round cable with solid or stranded wires, maintaining identical cable compatibility.

Q: What is the significance of the ROHS3 compliance on the SS-39100-021?

A: ROHS3 compliance indicates the substitute part meets current European Union Restriction of Hazardous Substances regulations. This is relevant for applications subject to regulatory compliance requirements.

Q: Are there packaging differences between these parts?

A: The SS-39100-003 packaging is not specified in available documentation. The SS-39100-021 is supplied in bulk packaging. Packaging format should be confirmed with the supplier based on specific procurement requirements.

Q: What inventory status should be considered for procurement planning?

A: The SS-39100-003 is obsolete with limited remaining inventory (783 Pcs). The SS-39100-021 is active with substantially higher inventory availability (8475 Pcs), supporting reliable procurement for ongoing production.
