A-RJ45GFS Modular Coupler Connector - Equivalent & Substitute Parts

Part Overview

The A-RJ45GFS is a modular coupler connector manufactured by Assmann WSW Components, designed to connect two 8P8C (RJ45) jack connectors. This shielded Cat5e coupler features a circular threaded coupling with panel mount, square flange configuration and IP67 ingress protection rating, making it suitable for industrial environments. The product is currently obsolete, necessitating identification of active equivalent alternatives that maintain functional and electrical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the A-RJ45GFS is determined by the following mandatory parameters:

• Connector type: Modular coupler with 8P8C (RJ45) jack-to-jack configuration
• Coupling mechanism: Circular threaded coupling
• Mounting configuration: Panel mount with square flange
• Electrical rating: Cat5e shielded
• Environmental protection: Minimum IP67 ingress protection
• Housing material: ABS plastic construction
• Contact finish: Gold plating
• Moisture sensitivity: MSL 1 (Unlimited)

Both identified substitute parts meet these core substitution criteria and are classified as active products with current manufacturing status.

Parameter Comparison

Engineering Selection Recommendations

1986172-1 (TE Connectivity AMP Connectors)

This substitute is an active product with RoHS compliance certification. The extended operating temperature range of -55°C to 105°C provides broader environmental capability compared to the original A-RJ45GFS specification. The CPC 45 series designation indicates a mature, production-qualified connector line. This part is suitable for applications requiring long-term component availability and compliance documentation.

PX0870 (Bulgin Ethernet Buccaneer®)

This substitute is an active product with ROHS3 compliance and REACH unaffected status. The enhanced ingress protection rating of IP68/IP69 exceeds the original IP67 specification, providing superior environmental sealing. Documented contact material (Phosphor Bronze) and contact finish thickness (50.0µin / 1.27µm) are specified. The operating temperature range of -20°C to 70°C is narrower than the TE Connectivity alternative. This part is appropriate for applications requiring enhanced environmental protection beyond the original specification.

Frequently Asked Questions (FAQ)

Q: Can 1986172-1 and PX0870 be used interchangeably with A-RJ45GFS?

A: Both parts meet the core substitution criteria: 8P8C (RJ45) jack-to-jack modular coupler configuration, circular threaded coupling, panel mount square flange mounting, Cat5e shielded rating, and ABS housing. Mechanical and electrical compatibility is established. Selection between them depends on specific application requirements regarding operating temperature range and ingress protection level.

Q: What is the difference in ingress protection between the substitutes?

A: The original A-RJ45GFS and 1986172-1 both specify IP67 (dust tight, waterproof). The PX0870 specifies IP68/IP69, which provides enhanced protection against continuous immersion and high-pressure water jets. Selection should be based on the actual environmental exposure conditions of the application.

Q: Are there packaging differences between these parts?

A: Yes. The A-RJ45GFS is supplied in unspecified packaging. The 1986172-1 is packaged in bags, while the PX0870 is packaged in boxes. Packaging format may affect inventory management and handling procedures but does not affect functional compatibility.

Q: What compliance certifications apply to each substitute?

A: The 1986172-1 is RoHS Compliant. The PX0870 is ROHS3 Compliant and REACH Unaffected. Both parts carry EAR99 ECCN classification. Compliance requirements should be verified against specific application and regional regulations.

Q: How do operating temperature ranges affect part selection?

A: The 1986172-1 operates from -55°C to 105°C, providing the widest temperature envelope. The PX0870 operates from -20°C to 70°C. The original A-RJ45GFS operating temperature is not specified. Selection should match the actual thermal environment where the connector will be deployed.
