Greenlee Communications 45743 Modular Connector Equivalent & Substitute Parts

Part Overview

The Greenlee Communications 45743 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 45743 has reached obsolete product status. Identifying equivalent substitute parts is necessary to maintain supply chain continuity and ensure ongoing availability for applications requiring this connector type.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Greenlee Communications 45743 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Connector Type: Plug
• Number of Positions/Contacts: 6P6C (RJ11, RJ12, RJ14, RJ25)
• Shielding: Unshielded
• Contact Finish: Gold
• Color: Translucent - Clear

Secondary Compatibility Criteria:

• Cable Type: Round Cable (solid or stranded wires acceptable)
• Termination Method: Crimp or IDC (both provide equivalent electrical connection)

The Stewart Connector 940-SP-3066R qualifies as a substitute because it maintains all primary compatibility criteria. The termination method differs (IDC versus crimp), but both methods provide equivalent electrical and mechanical performance for 6P6C modular connectors. The 940-SP-3066R accepts both solid and stranded wires, providing broader application flexibility than the original part.

Parameter Comparison

Engineering Selection Recommendations

The Stewart Connector 940-SP-3066R is the designated manufacturer-recommended substitute for the obsolete Greenlee Communications 45743.

Selection Basis:

The 940-SP-3066R maintains functional equivalence across all critical electrical and mechanical parameters. Both connectors are classified under identical HTSUS and ECCN codes, confirming regulatory alignment.

The 940-SP-3066R holds active product status with ROHS3 compliance, ensuring long-term availability and regulatory adherence for new designs and production continuity. The original 45743 is obsolete with no RoHS applicability designation.

The termination method transition from crimp to IDC does not compromise electrical performance for 6P6C modular connector applications. The IDC termination in the 940-SP-3066R accommodates both solid and stranded wire gauges, providing expanded application compatibility compared to the original crimp-only design.

Both connectors share identical shielding, contact finish, color, and connector type specifications, confirming direct functional substitution for existing applications.

Frequently Asked Questions (FAQ)

Q: Can the Stewart Connector 940-SP-3066R directly replace the Greenlee 45743 in existing applications?

A: Yes. Both connectors maintain identical specifications for connector type, position/contact configuration (6P6C), shielding (unshielded), contact finish (gold), and color (translucent clear). These parameters define functional compatibility for 6P6C modular connector applications.

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

A: The Greenlee 45743 uses crimp termination; the Stewart 940-SP-3066R uses IDC (Insulation Displacement Contact) termination. Both methods provide equivalent electrical connection for modular connectors. IDC termination does not require stripping wire insulation, while crimp termination requires pre-stripped wires. The 940-SP-3066R IDC design accommodates both solid and stranded wires.

Q: Does the 940-SP-3066R accept the same wire gauges as the 45743?

A: The 45743 specification limits cable type to round cable with solid wires. The 940-SP-3066R accepts round cable with both solid and stranded wires, providing broader wire gauge compatibility. Specific wire gauge ranges are not provided in the available technical data for either connector.

Q: Are there compliance differences between the two connectors?

A: The 940-SP-3066R is ROHS3 compliant with active product status. The 45743 is obsolete with RoHS status listed as not applicable. Both connectors share identical ECCN (EAR99) and HTSUS (8536.69.8000) classifications.

Q: What is the packaging configuration for the 940-SP-3066R?

A: The 940-SP-3066R is supplied in bulk packaging, with 106,564 pieces currently in stock. The original 45743 packaging specification is not provided.

Q: Are the physical dimensions identical between the two connectors?

A: The 940-SP-3066R length is specified as 0.525" (13.34mm). The 45743 length specification is not provided in the available technical data. Both connectors are 6P6C modular plugs with translucent clear housing, indicating standard form factor compatibility.
