Amphenol ICC 94910-304MLF Modular Connector RJ45 Jack — Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 94910-304MLF is a shielded modular jack connector (8p8c RJ45 Ethernet) with 90° right-angle orientation, designed for through-hole mounting with solder termination. This connector features an EMI finger for shielding and operates across -40°C to 70°C. The product is classified as obsolete, making equivalent substitutes necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 94910-304MLF is determined by the following core parameters:

• Connector Type & Configuration: All substitutes must be 8p8c (RJ45 Ethernet) jack connectors with 4 ports and 1 row
• Orientation & Mounting: 90° right-angle orientation with through-hole solder termination required
• Shielding: Shielded construction with EMI finger capability
• Tab Direction: Down-facing tab orientation
• Contact System: Gold-plated contacts with copper alloy or phosphor bronze material
• Environmental Rating: Operating temperature range and MSL compatibility

The four substitute parts listed below meet these core substitution criteria. Differences in contact finish thickness, housing material composition, and electrical ratings (Cat3 vs. Cat5e) represent acceptable variations within the modular connector category while maintaining functional equivalence for the specified application.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are active products with current manufacturing support, addressing the obsolescence status of the 94910-304MLF. Selection among substitutes should be based on the following factors:

SS-718804S-A-NF: Baseline Cat5e substitute without EMI finger. Suitable for applications where EMI filtering is not required. ROHS3 and REACH compliant.

SS-718804S-A-PG3-BA-A283: Cat5e substitute with EMI finger matching the original shielding specification. Includes board guide feature. ROHS3 and REACH compliant.

SS-718804S-A-PG4-BA: Cat5e substitute with EMI finger and board guide. Functionally equivalent to SS-718804S-A-PG3-BA-A283 with identical electrical and mechanical specifications. ROHS3 and REACH compliant.

SS-728804SFR1-A-NF: Stewart Connector Series 72 alternative with integrated filter feature and board guide. Shielded without specified EMI finger. ROHS3 and REACH compliant. Suitable for applications requiring additional EMI filtering beyond standard shielding.

All substitutes operate across -40°C to 85°C, exceeding the original -40°C to 70°C range. All maintain MSL 1 (Unlimited) rating and share identical ECCN and HTSUS classifications with the original part.

Frequently Asked Questions (FAQ)

Q: Can SS-718804S-A-NF be used as a direct replacement for 94910-304MLF?

A: SS-718804S-A-NF meets all core substitution criteria: 8p8c RJ45 jack, 90° right-angle, through-hole solder termination, 4 ports, down-facing tab, and shielded construction. The primary difference is the absence of an EMI finger. If EMI finger functionality is required for your application, use SS-718804S-A-PG3-BA-A283 or SS-718804S-A-PG4-BA instead.

Q: What is the difference between SS-718804S-A-PG3-BA-A283 and SS-718804S-A-PG4-BA?

A: Both parts are functionally equivalent Cat5e shielded jacks with EMI finger and board guide. They share identical electrical ratings, contact specifications, operating temperature range, and compliance certifications. Selection between them may depend on packaging availability (tray vs. alternative) or internal inventory management.

Q: Why do the substitute parts have higher contact finish thickness (30.0µin vs. 5.00µin)?

A: Contact finish thickness is a manufacturing specification that does not affect functional compatibility. The higher thickness on Stewart Connector parts provides equivalent or superior contact durability and electrical performance compared to the original Amphenol specification.

Q: Are all substitutes RoHS3 and REACH compliant?

A: Yes. All four substitute parts are ROHS3 Compliant and REACH Unaffected. The original 94910-304MLF does not specify these compliance statuses. If RoHS3 and REACH compliance is required for your application, any of the four substitutes are suitable.

Q: What is the difference between Cat3 and Cat5e ratings?

A: The original 94910-304MLF is rated Cat3 (Category 3, supporting up to 10 Mbps). All substitute parts are rated Cat5e (Category 5e, supporting up to 1 Gbps). Cat5e is backward compatible with Cat3 applications and provides superior performance headroom for future upgrades.

Q: Should I use SS-728804SFR1-A-NF if my application requires additional filtering?

A: SS-728804SFR1-A-NF includes an integrated filter feature in addition to shielding. This part is suitable if your application requires both shielded construction and active EMI filtering. Verify that the filter characteristics match your specific EMI suppression requirements.

Q: Are there any mechanical compatibility concerns when substituting these parts?

A: All substitutes maintain identical mechanical specifications: 90° right-angle orientation, through-hole mounting, down-facing tab direction, and 4-port configuration. Board-level mechanical compatibility is preserved. Verify PCB footprint compatibility with your specific board design before procurement.
