Greenlee Communications 9544 Modular Connector RJ45 Equivalent & Substitute Parts

Part Overview

The Greenlee Communications 9544 is a modular connector plug designed for 8-position 8-contact (8P8C) RJ45 Ethernet applications. This unshielded connector is rated for Cat5e performance and utilizes IDC (Insulation Displacement Contact) termination technology for round cable with stranded wires. The product is currently classified as obsolete, making identification of functionally equivalent active alternatives essential for ongoing system maintenance and new installations where this connector type is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Greenlee Communications 9544 is based on strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type: Plug configuration
• Contact count: 8P8C (RJ45, Ethernet) standard
• Shielding configuration: Unshielded
• Performance rating: Cat5e
• Termination technology: IDC
• Cable compatibility: Round cable with stranded wire support

The Stewart Connector SS-37000-002 satisfies all mandatory substitution criteria. Both connectors are designed for identical electrical and mechanical interfaces, supporting the same cable types and performance standards. The SS-37000-002 is an active product with current manufacturing status and full inventory availability, providing a direct functional replacement for the obsolete Greenlee 9544.

Parameter Comparison

Engineering Selection Recommendations

The Stewart Connector SS-37000-002 is the designated manufacturer-recommended substitute for the Greenlee Communications 9544. Selection of this alternative is supported by the following engineering factors:

Compliance and Regulatory Status: The SS-37000-002 maintains RoHS3 compliance, exceeding the RoHS compliance level of the original part. Both components carry identical ECCN (EAR99) and HTSUS (8536.69.8000) classifications, ensuring consistent regulatory treatment in procurement and supply chain documentation.

Product Lifecycle Status: The transition from the obsolete Greenlee 9544 to the active Stewart Connector SS-37000-002 ensures access to current manufacturing, quality assurance processes, and ongoing inventory availability. The SS-37000-002 is manufactured under active product status with 43,078 units in current stock.

Functional Equivalence: Both connectors meet identical electrical and mechanical specifications for 8P8C RJ45 Ethernet applications at Cat5e performance levels. The SS-37000-002 supports both solid and stranded wire configurations, providing expanded cable compatibility compared to the original specification.

Moisture Sensitivity: The SS-37000-002 carries MSL 1 (Unlimited) rating, indicating no moisture sensitivity constraints during storage and handling, compared to the original part's not-applicable MSL designation.

Frequently Asked Questions (FAQ)

Q: Can the Stewart Connector SS-37000-002 directly replace the Greenlee 9544 in existing installations?

A: Yes. Both connectors are 8P8C RJ45 plugs with unshielded, IDC termination for Cat5e applications. The mechanical and electrical interfaces are identical, allowing direct substitution without modification to mating equipment or cable assemblies.

Q: What is the significance of the SS-37000-002 supporting both solid and stranded wire types?

A: The original Greenlee 9544 specification limits compatibility to stranded wire. The SS-37000-002 expands this capability to accept both solid and stranded conductors within the same connector body, providing greater flexibility in cable sourcing without compromising performance.

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

A: Both parts carry EAR99 and identical HTSUS classifications. The SS-37000-002 achieves ROHS3 compliance, which represents a higher compliance standard than the RoHS compliance of the original part. This upgrade ensures compatibility with current and future regulatory requirements.

Q: What is the packaging difference between these parts?

A: The Greenlee 9544 packaging specification is not provided in available documentation. The Stewart Connector SS-37000-002 is supplied in bulk packaging, suitable for high-volume assembly operations and component distribution.

Q: Does the SS-37000-002 provide electrical performance specifications not listed for the original part?

A: Yes. The SS-37000-002 includes specified voltage rating (150V) and current rating (1.5 A), along with contact material (Phosphor Bronze) and finish specifications (Gold, 50.0µin thickness). These specifications confirm performance capability for standard Ethernet applications but do not alter the Cat5e performance equivalence between the two connectors.

Q: What is the MSL rating significance for the SS-37000-002?

A: MSL 1 (Unlimited) indicates the connector has no moisture sensitivity constraints. Components may be stored and handled under standard environmental conditions without desiccant packaging or time-limited shelf life restrictions, simplifying inventory management and logistics.
