Greenlee Communications 45776 Modular Connector Equivalent & Substitute Parts

Part Overview

The Greenlee Communications 45776 is a modular connector plug designed for 6-position 6-contact (6P6C) applications including RJ11, RJ12, RJ14, and RJ25 configurations. This unshielded connector features crimp termination for round cable with solid wires and gold-plated contacts with translucent clear housing.

The 45776 has reached obsolete product status. Identifying equivalent substitute parts is necessary to maintain supply chain continuity and ensure ongoing availability for applications requiring 6P6C modular plug connectivity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Greenlee Communications 45776 is based on the following critical parameters that must remain consistent:

Core Compatibility Parameters:

• Connector type: Plug configuration
• Contact count: 6P6C (RJ11, RJ12, RJ14, RJ25 compatible)
• Shielding: Unshielded design
• Contact finish: Gold plating
• Housing color: Translucent clear

Termination Compatibility: The 45776 uses crimp termination for solid wires. Substitute parts may employ alternative termination methods (such as IDC) provided they maintain compatibility with the same cable types and contact configurations. The Stewart Connector 940-SP-3066R qualifies as a substitute because it accommodates both solid and stranded wires through IDC termination while maintaining all core electrical and mechanical parameters.

Engineering Selection Recommendations

Primary Substitute: Stewart Connector 940-SP-3066R

The Stewart Connector 940-SP-3066R is the manufacturer-recommended substitute for the obsolete Greenlee Communications 45776. This part maintains all critical electrical and mechanical parameters required for 6P6C modular plug applications.

Compliance and Status Advantages:

• Active product status ensures ongoing availability and supply chain reliability
• ROHS3 compliance meets current environmental and regulatory requirements
• REACH unaffected status confirms compliance with chemical substance regulations
• EAR99 ECCN classification maintains export compliance

Technical Compatibility: The 940-SP-3066R preserves the core functional requirements: 6P6C connector configuration, unshielded design, gold-plated contacts, and translucent clear housing. The IDC termination method provides enhanced versatility by accommodating both solid and stranded wire types, expanding application flexibility compared to the crimp-only design of the 45776.

Electrical Performance: The substitute part provides specified electrical ratings (1.5 A current, 150V voltage) that establish clear performance boundaries for circuit design, whereas the original part lacked published ratings.

Frequently Asked Questions (FAQ)

Q: Can the Stewart Connector 940-SP-3066R directly replace the Greenlee 45776 in existing applications?

A: Yes. Both parts maintain identical 6P6C connector configuration, unshielded design, gold contact finish, and translucent clear housing. The 940-SP-3066R is the manufacturer-recommended substitute and qualifies for direct replacement in applications originally designed for the 45776.

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

A: The 45776 uses crimp termination, which requires mechanical compression of contacts onto solid wires. The 940-SP-3066R uses IDC (Insulation Displacement Contact) termination, which pierces wire insulation without requiring separate crimping tools. IDC termination accommodates both solid and stranded wires, providing greater flexibility.

Q: Are there cable type compatibility differences?

A: The 45776 is specified for solid wires only. The 940-SP-3066R accommodates both solid and stranded wires through its IDC termination design. Applications using solid wire cables remain fully compatible with the substitute part.

Q: What compliance certifications apply to the substitute part?

A: The Stewart Connector 940-SP-3066R holds ROHS3 compliance and REACH unaffected status, meeting current environmental regulations. The original 45776 lists RoHS status as "Not applicable" due to its obsolete status.

Q: Does the substitute part maintain the same physical dimensions?

A: The 940-SP-3066R specifies a length of 0.525" (13.34mm). The original 45776 does not provide length specifications in available documentation. Both parts maintain the standard 6P6C form factor for RJ11, RJ12, RJ14, and RJ25 applications.

Q: What electrical ratings should be used for circuit design?

A: The 940-SP-3066R provides specified ratings of 1.5 A current capacity and 150V voltage rating. These values establish the electrical performance envelope for applications using this substitute part. The original 45776 does not provide published electrical ratings.

Q: Is the substitute part available in bulk packaging?

A: Yes. The Stewart Connector 940-SP-3066R is available in bulk packaging with high inventory levels (106,564 pieces in stock), ensuring reliable supply for production requirements.
