Substitute Part Grouping Explanation

Substitution of the Amphenol ICC 90520-003 with the Molex 0424106168 is based on strict equivalence of the following critical parameters:

• Connector Type: Both are jack connectors
• Contact Configuration: Both support 6p6c (RJ11, RJ12, RJ14, RJ25)
• Mounting and Orientation: Both feature through-hole vertical mounting
• Termination Method: Both use solder termination
• Shielding: Both are unshielded
• Performance Rating: Both meet Cat3 specifications
• Port and Row Configuration: Both have 1 port and 1 row
• Tab Direction: Both support user-selectable tab direction
• Contact Finish: Both feature gold-plated contacts
• LED Status: Neither contains LED functionality
• Regulatory Compliance: Both are RoHS compliant and carry EAR99 classification

These parameters define the functional and mechanical interchangeability of the substitute part within the same application context.

Parameter Comparison

Engineering Selection Recommendations

Both the Amphenol ICC 90520-003 and Molex 0424106168 are active production parts with equivalent functional specifications for 6p6c modular jack applications. Selection between these parts should be based on the following factors:

Amphenol ICC 90520-003 is suitable when:

• Copper alloy contact material is specified in design requirements
• Operating temperature range of -40°C to 70°C is sufficient
• Thinner gold plating (5.00µin) meets contact durability specifications
• RoHS Compliant certification is required

Molex 0424106168 is suitable when:

• Phosphor bronze contact material is preferred for enhanced spring properties
• Extended operating temperature range to 80°C is required
• Thicker gold plating (50.0µin) is specified for increased contact longevity
• ROHS3 Compliant certification is required

Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, indicating equivalent export and tariff treatment. Both maintain MSL 1 (Unlimited) moisture sensitivity ratings, eliminating special storage or handling requirements.

Frequently Asked Questions (FAQ)

Q: Are the Amphenol ICC 90520-003 and Molex 0424106168 mechanically interchangeable?

A: Yes. Both connectors feature identical mounting type (through hole), orientation (vertical), port configuration (1 port, 1 row), and tab direction (user selectable). Physical dimensions and PCB footprints are compatible for direct substitution.

Q: What is the difference in contact material between these parts?

A: The Amphenol ICC 90520-003 uses copper alloy contacts, while the Molex 0424106168 uses phosphor bronze. Phosphor bronze typically provides superior spring characteristics and wear resistance. The choice depends on application-specific contact force and durability requirements.

Q: Do the differences in gold plating thickness affect compatibility?

A: Both parts meet Cat3 electrical specifications with gold-plated contacts. The Amphenol ICC part has 5.00µin plating thickness, while the Molex part has 50.0µin thickness. Thicker plating generally provides extended contact life in high-cycle applications. Selection should align with expected mating cycles and contact wear specifications.

Q: What is the significance of the operating temperature range difference?

A: The Amphenol ICC 90520-003 operates from -40°C to 70°C, while the Molex 0424106168 extends to 80°C. For applications requiring sustained operation above 70°C, the Molex part is the appropriate selection. For standard temperature environments, both parts are equivalent.

Q: Are both parts RoHS compliant?

A: Yes. The Amphenol ICC 90520-003 is RoHS Compliant, and the Molex 0424106168 is ROHS3 Compliant. Both meet RoHS requirements; ROHS3 represents a more recent certification standard. Both parts are suitable for RoHS-regulated applications.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided that the design does not specify constraints on contact material, operating temperature range, or gold plating thickness. Both parts support identical RJ11, RJ12, RJ14, and RJ25 standards and carry equivalent regulatory classifications (EAR99, HTSUS 8536.69.4040).

Q: What is the packaging format for both parts?

A: Both parts are supplied in tray packaging, suitable for automated assembly processes and standard component handling.
