SS-79100-003 SFP+ Cage Connector Press-Fit Right Angle Equivalent & Substitute Parts

Part Overview

The SS-79100-003 is an active SFP+ cage connector manufactured by Stewart Connector, designed for press-fit through-hole mounting in right-angle orientation. This component functions as a receptacle interface for SFP+ transceiver modules in high-speed optical communication systems. The connector features EMI shielding and integrated light pipe functionality to support reliable signal transmission and module identification. With 808 units in current stock and active product status, this part remains available for new designs and production applications. Equivalent substitute parts are identified to provide procurement flexibility, supply chain redundancy, and alternative sourcing options when the primary part becomes unavailable or when design requirements necessitate alternative manufacturer specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SS-79100-003 is determined by strict equivalence across the following critical parameters:

• Connector Type: SFP+ (optical transceiver interface standard)
• Connector Style: Cage (mechanical form factor)
• Mounting Type: Through Hole, Right Angle (PCB integration method and orientation)
• Termination Method: Press-Fit (connection to PCB without soldering)
• Features: EMI Shielded, Light Pipe (functional requirements for signal integrity and module identification)
• Packaging: Tray (supply format)
• RoHS Status: ROHS3 Compliant (environmental and regulatory requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (storage and handling classification)

The identified substitute part 2110929-1 from TE Connectivity AMP Connectors meets all these criteria, establishing direct functional and mechanical equivalence for component selection and replacement purposes.

Parameter Comparison

Engineering Selection Recommendations

Both the SS-79100-003 and 2110929-1 are active products with ROHS3 compliance and identical functional specifications. Selection between these parts should be based on:

• Availability: The 2110929-1 currently maintains higher inventory (1090 units) compared to SS-79100-003 (808 units), providing supply assurance for high-volume production requirements.
• Manufacturer preference: Stewart Connector and TE Connectivity AMP Connectors are both established manufacturers in the pluggable connector market. Design documentation and qualification history may favor one manufacturer over the other based on existing supply chain relationships.
• Regulatory compliance: Both parts satisfy ROHS3 requirements. The SS-79100-003 carries REACH Unaffected status, while 2110929-1 shows Vendor Undefined REACH status. For applications requiring explicit REACH compliance documentation, the SS-79100-003 may be preferred.
• Tariff classification: HTSUS codes differ (SS-79100-003: 8538.90.8180 vs. 2110929-1: 8536.69.4040), which may impact landed cost and duty calculations for international procurement.

Frequently Asked Questions (FAQ)

Q: Can 2110929-1 be used as a direct replacement for SS-79100-003 in existing designs?

A: Yes. Both parts are functionally and mechanically equivalent across all critical parameters: SFP+ connector type, cage style, through-hole right-angle mounting, press-fit termination, EMI shielding, and light pipe features. No design modifications are required for substitution.

Q: Are there any differences in press-fit contact specifications between these parts?

A: Contact finish and contact finish thickness specifications are not provided in the available technical data for either part. Detailed contact specifications should be obtained from manufacturer datasheets to confirm compatibility with specific PCB pad designs and press-fit equipment parameters.

Q: What is the significance of the different HTSUS codes?

A: HTSUS codes classify products for tariff and duty purposes. The different codes (8538.90.8180 for SS-79100-003 and 8536.69.4040 for 2110929-1) may result in different duty rates depending on country of origin and import destination. Procurement teams should consult with customs brokers for accurate landed cost calculations.

Q: Does the REACH Unaffected status of SS-79100-003 versus Vendor Undefined for 2110929-1 affect component selection?

A: For applications subject to REACH regulations, the SS-79100-003 with explicit REACH Unaffected status provides documented compliance. The 2110929-1 with Vendor Undefined status requires clarification from TE Connectivity regarding REACH applicability. Regulatory requirements should drive selection in compliance-critical applications.

Q: Are both parts suitable for high-speed optical communication systems?

A: Both parts are specified as SFP+ cage connectors with EMI shielding and light pipe features, indicating suitability for high-speed optical transceiver applications. Specific performance validation should be conducted according to system requirements and applicable standards (such as SFP+ MSA specifications).

Q: What is the Moisture Sensitivity Level 1 (Unlimited) classification?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. These parts can be stored and handled without special humidity controls or floor-life limitations, simplifying inventory management and supply chain logistics.
