Greenlee Communications 45750 Modular Connector Equivalent & Substitute Parts

Part Overview

The Greenlee Communications 45750 is a modular plug connector with 6 positions and 4 contacts (6P4C), conforming to RJ11 and RJ14 standards. This unshielded connector is designed for flat oval cable with stranded wires and utilizes crimp termination. The product is classified as obsolete, necessitating identification of active equivalent components that maintain functional and electrical compatibility for ongoing applications and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Greenlee Communications 45750 is determined by the following critical parameters that must remain consistent:

Mandatory Matching Parameters:

• Connector Type: Plug
• Number of Positions/Contacts: 6P4C (RJ11, RJ14)
• Shielding: Unshielded
• Cable Type: Flat Oval Cable, Stranded Wires
• Color: Translucent - Clear
• Contact Finish: Gold

The Assmann WSW Components A-MO 6/4-F50 satisfies all mandatory parameters. While the termination method differs (IDC versus crimp), both termination types are functionally compatible with 6P4C modular connector applications. The substitute part is active and carries current regulatory compliance certifications (ROHS3, REACH Unaffected, EAR99), addressing the obsolescence of the original component.

Parameter Comparison

Engineering Selection Recommendations

The Assmann WSW Components A-MO 6/4-F50 is the designated substitute for the obsolete Greenlee Communications 45750. Selection of this substitute is based on the following engineering criteria:

Product Status Alignment: The substitute part maintains active product status with current manufacturing support, addressing the obsolescence limitation of the original component.

Regulatory Compliance: The A-MO 6/4-F50 carries ROHS3 compliance and REACH Unaffected status, meeting current environmental and regulatory requirements. The original part lists RoHS status as not applicable due to its obsolete classification.

Functional Equivalence: Both connectors maintain identical 6P4C modular connector specifications, unshielded configuration, and gold contact finish. The connector type, position count, and cable compatibility remain unchanged.

Termination Consideration: The substitute employs IDC (Insulation Displacement Contact) termination rather than crimp. IDC termination is functionally compatible with 6P4C modular connector applications and is widely used in equivalent connector designs.

Electrical Ratings: The substitute provides specified electrical ratings (250V, 2A) that establish performance boundaries for the connector in operational circuits.

Frequently Asked Questions (FAQ)

Q: Why is the Greenlee 45750 being replaced?

A: The Greenlee Communications 45750 is classified as obsolete. The Assmann A-MO 6/4-F50 provides functional equivalence with active product status and current regulatory compliance.

Q: Are the connectors mechanically compatible?

A: Both connectors are 6P4C modular plugs designed for flat oval cable with stranded wires. The physical form factor and contact arrangement are equivalent.

Q: What is the difference between crimp and IDC termination?

A: The original part uses crimp termination; the substitute uses IDC (Insulation Displacement Contact) termination. Both termination methods are functionally compatible with 6P4C modular connector applications and produce equivalent electrical connections.

Q: Does the substitute meet current regulatory requirements?

A: Yes. The Assmann A-MO 6/4-F50 is ROHS3 compliant and REACH Unaffected, meeting current environmental and regulatory standards.

Q: Are the electrical ratings specified for both parts?

A: The original Greenlee 45750 does not provide specified voltage or current ratings. The substitute Assmann A-MO 6/4-F50 is rated for 250V and 2A.

Q: What is the packaging difference?

A: The original part packaging is not specified. The substitute is supplied in bulk packaging with 49,802 pieces available in current inventory.

Q: Is the color the same?

A: Both connectors are translucent clear, maintaining visual consistency in applications.
