94911-508MLF Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 94911-508MLF is a modular jack connector (8p8c/RJ45) with 90° right-angle orientation, unshielded design, and through-hole solder termination. This connector is rated for Cat3 applications and features a board lock mechanism. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations where legacy compatibility is required.

Substitute Part Grouping Explanation

Substitution eligibility for the 94911-508MLF is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

Connector type: Jack modular connector
Configuration: 8p8c (RJ45, Ethernet)
Orientation: 90° right-angle
Mounting type: Through hole
Termination: Solder
Shielding: Unshielded
Port count: 8
Row count: 1
Tab direction: Down
Contact material: Phosphor Bronze

Engineering Selection Recommendations

The Molex 0432238176 is a qualified substitute for the obsolete Amphenol ICC 94911-508MLF based on the following engineering criteria:

Functional Equivalence: All mandatory electrical and mechanical parameters align precisely. Both connectors are 8p8c jack modules with identical orientation, mounting, termination, and contact specifications.

Performance Enhancement: The substitute provides Cat4 rating versus the original Cat3, representing improved performance headroom for Ethernet applications without introducing incompatibility.

Compliance Status: The Molex part maintains RoHS3 compliance and unlimited MSL rating, meeting current regulatory requirements. Both parts carry EAR99 ECCN classification.

Production Availability: The substitute is in active production status with confirmed inventory (1071 pcs), whereas the original is obsolete. This ensures long-term supply chain viability.

Temperature Consideration: The substitute operates within -40°C to 85°C, which is narrower than the original -65°C to 125°C range. Verify this range is acceptable for the target application environment before final selection.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0432238176 be used as a direct replacement in existing PCB designs?

A: Yes. The connector maintains identical footprint, orientation, mounting type, and solder termination. No PCB redesign is required. The substitute is mechanically and electrically compatible with the original 94911-508MLF.

Q: What is the difference between Cat3 and Cat4 ratings?

A: Cat4 represents a higher performance classification for Ethernet applications, supporting greater bandwidth and data transmission rates. Using a Cat4 connector in a Cat3 application introduces no compatibility issues and provides performance margin.

Q: Are there any temperature limitations when substituting?

A: The Molex substitute operates from -40°C to 85°C, compared to the original -65°C to 125°C. If your application requires operation below -40°C or above 85°C, the substitute is not suitable. Verify your operating environment specifications before selection.

Q: Does the housing material difference affect performance?

A: Both housings are glass-filled thermoplastic materials. The Molex uses polyamide (PA) nylon formulation while the original uses generic thermoplastic. Both provide equivalent mechanical strength and environmental resistance for this connector class.

Q: Is the Molex part available in the same packaging?

A: The Molex 0432238176 is supplied in tray packaging. Confirm packaging requirements for your procurement and assembly processes.

Q: Are both parts RoHS compliant?

A: Yes. The original is RoHS compliant, and the substitute is ROHS3 compliant, meeting current and future regulatory requirements.
