Phoenix Contact 1688586 Modular Connector RJ45 Jack 8P8C Right Angle Shielded

Part Overview

The Phoenix Contact 1688586 is a modular connector jack (8P8C/RJ45) configured for 90° right angle mounting with shielding suitable for Cat5e Ethernet applications. This connector features through-hole solder termination and is rated for -40°C to 85°C operation. The product is currently obsolete, necessitating identification of functionally equivalent alternatives from active manufacturers for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1688586 is determined by the following critical parameters:

Primary Compatibility Criteria:

Connector type: 8P8C jack (RJ45 Ethernet)
Mounting configuration: Through-hole solder termination
Mechanical orientation: 90° right angle
Electrical shielding: Shielded construction
Operating temperature: -40°C minimum to 85°C maximum
Contact finish: Gold plating
Compliance: ROHS3 compliant

Substitution Categories:

Direct Equivalents (Shielded, Cat5e/Cat5): Parts meeting all primary criteria with shielded construction and Cat5/Cat5e ratings. These include Amphenol ICC 95678-001LF, 95678-001ALF, and 95678-101ALF, which maintain identical mechanical and electrical interfaces.

Functional Alternatives (Shielded, Different Category): TE Connectivity 5557791-1 provides shielded construction with Cat3 rating and identical mechanical form factor, suitable where Cat3 performance is acceptable.

Unshielded Alternative: Phoenix Contact 1149870 maintains identical mechanical configuration and operating temperature but removes shielding, applicable only where EMI protection is not required.

Integrated RJ45 Module: Würth Elektronik 7499011001A integrates RJ45 functionality with 10/100 Base-T and AutoMDIX support in a shielded through-hole package, suitable for applications requiring active network features.

Engineering Selection Recommendations

For Direct Replacement (Shielded, Cat5/Cat5e, Extended Temperature): Amphenol ICC 95678-001LF or 95678-001ALF are preferred substitutes. Both maintain shielded construction with EMI fingers, Cat5 rating, and active product status. The 95678-001LF is recommended as primary choice due to REACH Unaffected status. Operating temperature is limited to -40°C to 70°C; applications requiring 85°C operation require thermal analysis.

For Cost-Optimized Shielded Alternative: TE Connectivity 5557791-1 provides shielded construction with board guide and shorting features at active status. Cat3 rating is suitable for legacy Ethernet applications where Cat5e performance is not required.

For Unshielded Applications: Phoenix Contact 1149870 maintains identical mechanical configuration and full -40°C to 85°C temperature range. Selection is limited to applications where electromagnetic shielding is not a functional requirement.

For Integrated Network Functionality: Würth Elektronik 7499011001A integrates 10/100 Base-T and AutoMDIX capabilities in shielded through-hole form factor. Selection is appropriate where active network features provide system-level advantages.

Frequently Asked Questions (FAQ)

Q: Can 95678-001LF directly replace 1688586 in all applications? A: Mechanical and electrical interfaces are compatible. Operating temperature maximum is reduced from 85°C to 70°C. Thermal analysis is required for applications operating above 70°C.

Q: What is the difference between 95678-001LF and 95678-001ALF? A: Both are electrically and mechanically identical. 95678-001ALF includes GXT™ gold finish with increased thickness (15.0µin vs. 5.00µin). Selection depends on contact durability requirements and mating cycle specifications.

Q: Is 1149870 suitable as a substitute? A: 1149870 is mechanically compatible but removes shielding. Selection is limited to applications where EMI protection is not required. Electrical performance in shielded environments will be degraded.

Q: What is the advantage of 7499011001A over standard RJ45 jacks? A: 7499011001A integrates 10/100 Base-T and AutoMDIX functionality, eliminating external magnetics and reducing component count. Selection is appropriate for applications requiring active network features.

Q: Are all substitutes ROHS3 compliant? A: 1149870, 5557791-1, and 7499011001A are ROHS3 compliant. Amphenol ICC parts (95678 series) are RoHS compliant but not explicitly ROHS3 certified. Compliance verification with procurement is required for ROHS3-mandated applications.

Q: What packaging formats are available? A: Phoenix Contact 1688586 and 1149870 are supplied in standard packaging. TE Connectivity 5557791-1 is supplied in trays. Würth Elektronik 7499011001A and Amphenol ICC 95678 series are supplied in tubes. Packaging selection affects handling and storage procedures.
