Engineering Selection Recommendations

The Amphenol ICC RJHSE508004 is the designated substitute for the obsolete Molex 0442480002. Selection is based on the following engineering factors:

Compliance & Availability: The Amphenol ICC part maintains RoHS compliance and is in active production status, ensuring long-term availability and supply chain continuity. The Molex component is obsolete and no longer manufactured.

Electrical & Mechanical Equivalence: Both connectors share identical contact configurations (8p8c), termination methods (solder), and shielding specifications (unshielded). The contact material, finish type, and finish thickness are identical, ensuring electrical performance parity.

Environmental Performance: The Amphenol ICC substitute provides an extended operating temperature range (-55°C to 85°C) compared to the original Molex part (-40°C to 85°C), offering improved performance in low-temperature applications while maintaining the upper temperature limit.

Moisture Sensitivity: Both components carry MSL 1 rating, indicating unlimited shelf life and no special moisture control requirements during storage or handling.

Physical Integration: Through-hole mounting, 90° right-angle orientation, four-port configuration, and board lock features are preserved in the substitute, enabling direct mechanical replacement without PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC RJHSE508004 be used as a direct replacement for the Molex 0442480002?

A: Yes. Both connectors share identical contact configurations, mounting methods, termination types, and electrical specifications. The substitute maintains all critical parameters required for functional equivalence in 8p8c modular jack applications.

Q: What is the difference in housing material between the two parts?

A: The Molex 0442480002 uses polybutylene terephthalate (PBT) with polyester and glass filler, while the Amphenol ICC RJHSE508004 uses thermoplastic material. Both materials provide adequate mechanical strength and environmental resistance for through-hole mounted connectors in standard operating conditions.

Q: Does the Amphenol ICC part support the same temperature range?

A: The Amphenol ICC RJHSE508004 supports -55°C to 85°C, which extends the lower temperature limit by 15°C compared to the Molex original (-40°C to 85°C). Both maintain the same upper temperature limit of 85°C.

Q: Are there any compliance differences between the two parts?

A: Both components are RoHS compliant and carry MSL 1 ratings. The Molex part is RoHS3 compliant, while the Amphenol ICC part is RoHS compliant. Both meet environmental and regulatory requirements for electronic component use.

Q: What packaging is available for the substitute part?

A: The Amphenol ICC RJHSE508004 is supplied in tube packaging, suitable for automated assembly and manual component handling.

Q: Are the contact finish specifications identical?

A: Yes. Both parts feature gold-plated phosphor bronze contacts with 50.0µin (1.27µm) finish thickness, ensuring equivalent electrical conductivity and corrosion resistance.
