Equivalent & Substitute Parts for 94910-308MLF

Part Overview

The 94910-308MLF is a Jack Modular Connector (8p8c/RJ45 Ethernet) manufactured by Amphenol ICC (FCI) with 90° right-angle orientation, through-hole solder termination, and shielding with EMI finger. This connector is rated for Cat3 applications and features a board lock mechanism. The product is currently obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 94910-308MLF is determined by strict alignment with the following core parameters:

• Connector Type & Configuration: Must be Jack, 8p8c (RJ45, Ethernet)
• Orientation & Mounting: Must maintain 90° right-angle orientation with through-hole solder termination
• Shielding Architecture: Must include shielding with EMI finger protection
• Electrical Rating: Must support Cat3 or higher (Cat5, Cat5e acceptable as backward-compatible upgrades)
• Physical Interface: Tab direction down, single row, 8 ports
• Environmental Compliance: Must maintain MSL 1 rating and REACH compliance status

The identified substitute parts meet these criteria while offering enhanced specifications in certain areas (higher temperature ratings, improved contact finish thickness, or higher category ratings).

Parameter Comparison

Engineering Selection Recommendations

6339169-3 (TE Connectivity AMP Connectors) is the manufacturer-recommended substitute. This part maintains full mechanical and electrical compatibility with the 94910-308MLF while offering enhanced specifications: Cat5 rating (versus Cat3), extended operating temperature range to 85°C, and significantly improved contact finish thickness (50.0µin versus 5.00µin). The part is currently in active production status with 2200 units in stock. RoHS3 compliance is confirmed, supporting modern regulatory requirements.

SS-718808S-A-NF (Stewart Connector) provides an alternative substitute with Cat5e rating and active product status. This connector features both board guide and board lock features, compared to board lock only on the original part. Operating temperature extends to 85°C. Contact finish thickness is 30.0µin. RoHS3 compliance and REACH Unaffected status are confirmed. Housing material differs (thermoplastic versus glass-filled thermoplastic), and contact material is copper alloy rather than phosphor bronze.

Both substitutes are electrically and mechanically compatible with the obsolete 94910-308MLF for through-hole solder applications requiring 8p8c right-angle shielded connectors with EMI protection.

Frequently Asked Questions (FAQ)

Q: Can 6339169-3 or SS-718808S-A-NF be used as direct replacements for 94910-308MLF in existing designs?

A: Yes. Both substitute parts maintain identical mechanical interfaces (90° right-angle, through-hole solder termination, 8p8c configuration, tab direction down) and shielding architecture. The higher electrical ratings (Cat5 and Cat5e versus Cat3) are backward-compatible upgrades that do not affect functionality in Cat3 applications.

Q: What is the significance of the contact finish thickness difference?

A: Contact finish thickness affects durability and wear resistance. The 94910-308MLF specifies 5.00µin, while 6339169-3 provides 50.0µin and SS-718808S-A-NF provides 30.0µin. Thicker gold plating extends contact life and improves corrosion resistance, particularly in environments with thermal cycling or high humidity.

Q: Are there differences in housing material that affect performance?

A: The 94910-308MLF uses thermoplastic with glass filler for enhanced mechanical strength. The 6339169-3 uses PCT (polycyclohexylenedimethylene terephthalate) with polyester, and SS-718808S-A-NF uses standard thermoplastic. These material differences do not affect electrical performance or shielding effectiveness for standard Ethernet applications. Material selection may influence mechanical robustness in high-vibration or extreme-temperature environments.

Q: Why is the operating temperature range different?

A: The 94910-308MLF is rated -40°C to 70°C, while both substitutes extend to -40°C to 85°C. This reflects design improvements in the substitute parts. For applications operating within the original -40°C to 70°C range, both substitutes remain fully compatible.

Q: What is the difference between EMI Finger shielding and standard shielding?

A: The 94910-308MLF and 6339169-3 both specify shielding with EMI finger, which provides enhanced electromagnetic interference rejection through finger-like contact elements. The SS-718808S-A-NF specifies shielding without explicit EMI finger designation. For applications requiring maximum EMI suppression, 6339169-3 is preferred.

Q: Are all three parts RoHS and REACH compliant?

A: The 94910-308MLF is REACH Unaffected. The 6339169-3 is ROHS3 Compliant with Vendor Undefined REACH status. The SS-718808S-A-NF is ROHS3 Compliant and REACH Unaffected. For new designs requiring full regulatory compliance, SS-718808S-A-NF or 6339169-3 are recommended.

Q: What inventory availability should be considered?

A: The 94910-308MLF (obsolete) has 1107 units in stock. The 6339169-3 has 2200 units available, and SS-718808S-A-NF has 932 units. For long-term procurement, 6339169-3 offers the highest availability and active product status.
