PA9540 Modular Connector Plug 6P6C Equivalent & Substitute Parts

Part Overview

The PA9540 is a modular connector plug manufactured by Greenlee Communications, designed for 6-position 6-contact (6P6C) applications including RJ11, RJ12, RJ14, and RJ25 configurations. This unshielded plug connector utilizes IDC (Insulation Displacement Contact) termination for round cable with solid wires and features a translucent clear housing.

The PA9540 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this connector type.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PA9540 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Connector Type: Must be Plug
• Number of Positions/Contacts: Must be 6P6C (RJ11, RJ12, RJ14, RJ25)
• Shielding: Must be Unshielded
• Termination Method: Must be IDC

Secondary Compatibility Criteria:

• Color: Translucent - Clear
• RoHS Compliance: RoHS Compliant or higher standard

The substitute part 940-SP-3066 manufactured by Stewart Connector satisfies all primary compatibility criteria. While the substitute accepts flat oval cable in addition to round cable, and provides additional electrical specifications (contact finish, voltage rating, current rating), the core functional parameters align with the PA9540 requirements for 6P6C unshielded IDC plug applications.

Engineering Selection Recommendations

940-SP-3066 as Primary Substitute:

The 940-SP-3066 is the designated manufacturer-recommended substitute for the PA9540. Selection of this part is based on the following engineering factors:

1. Functional Equivalence: Both connectors meet the core 6P6C unshielded IDC plug specification for RJ11, RJ12, RJ14, and RJ25 applications.

2. Product Status: The 940-SP-3066 maintains active production status, ensuring long-term availability and supply chain reliability compared to the obsolete PA9540.

3. Compliance Standards: The 940-SP-3066 exceeds the RoHS compliance level of the PA9540, meeting ROHS3 standards. Both parts carry EAR99 ECCN classification and identical HTSUS codes (8536.69.8000).

4. Electrical Specifications: The 940-SP-3066 provides defined electrical ratings (150V, 1.5 A) and material specifications (Phosphor Bronze contacts with gold finish, Polycarbonate housing) that support reliable performance in standard telecommunications and data applications.

5. Cable Compatibility: The 940-SP-3066 accommodates both round and flat oval cable types with solid or stranded wires, providing broader application flexibility than the PA9540 specification.

Frequently Asked Questions (FAQ)

Q: Can the 940-SP-3066 directly replace the PA9540 in existing designs?

A: Yes. Both connectors are 6P6C unshielded IDC plugs with identical contact positioning and RJ11/RJ12/RJ14/RJ25 compatibility. The 940-SP-3066 accepts the same round cable type specified for the PA9540, ensuring mechanical and electrical compatibility.

Q: What is the primary difference between these two connectors?

A: The PA9540 is obsolete with limited technical specifications provided. The 940-SP-3066 is an active product with fully defined electrical ratings, material composition, and cable type flexibility. The 940-SP-3066 accepts both round and flat oval cables, whereas the PA9540 specification limits to round cable.

Q: Are there any compliance concerns when substituting the PA9540 with the 940-SP-3066?

A: No. The 940-SP-3066 maintains equivalent or superior compliance status. Both parts are RoHS compliant; the 940-SP-3066 meets the higher ROHS3 standard. Both carry identical ECCN and HTSUS classifications.

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

A: The 940-SP-3066 is supplied in bulk packaging with high inventory availability (84,667 pieces in stock).

Q: Are the electrical ratings of the 940-SP-3066 suitable for standard telecommunications applications?

A: Yes. The 940-SP-3066 is rated for 150V and 1.5 A, which aligns with standard telecommunications and low-voltage data applications for 6P6C modular connectors.
