ISPS688FAS Equivalent & Substitute Parts

Part Overview

The ISPS688FAS is an 8-position shielded modular connector (RJ45/Ethernet) manufactured by Panduit Corp, designed for IndustrialNet™ applications. This connector is classified as obsolete, necessitating identification of equivalent substitute components for ongoing system maintenance and new installations where legacy compatibility is required. The part features IDC termination for round cable (solid or stranded wires) and is rated for Cat6a performance with IP20 ingress protection.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ISPS688FAS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type: Plug configuration
• Position count: 8p8c (RJ45/Ethernet standard)
• Shielding: Shielded construction
• Category rating: Cat6a performance specification
• Termination: IDC (Insulation Displacement Contact)
• Cable compatibility: Round cable with solid or stranded wires
• Wire gauge range: 22-27 AWG (substitute must accommodate this range)
• Ingress protection: IP20 minimum
• Housing material: Polycarbonate (PC)
• Contact finish: Gold plating
• Regulatory compliance: ROHS3 Compliant

The substitute part 1300478008 (Molex) meets all mandatory parameters and is therefore classified as a direct equivalent for the obsolete ISPS688FAS.

Parameter Comparison

Engineering Selection Recommendations

The Molex 1300478008 is a direct functional equivalent to the obsolete Panduit ISPS688FAS for the following reasons:

Compliance and Regulatory Status: Both components are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8536.69.8000) classifications, ensuring regulatory equivalence for procurement and export purposes.

Electrical and Mechanical Specifications: The substitute part maintains identical Cat6a performance ratings, IDC termination methodology, shielding configuration, and contact metallurgy (gold finish at 31.5µin thickness). Physical dimensions are equivalent within manufacturing tolerance (0.004" length variance).

Connector Interface Compatibility: Both parts conform to the 8p8c (RJ45/Ethernet) standard, ensuring mechanical and electrical interchangeability with mating connectors and cable assemblies designed for this interface.

Wire Gauge Consideration: The Molex substitute accommodates 22-24 AWG wire, which is a subset of the original 22-27 AWG specification. For applications using 25-27 AWG wire, the ISPS688FAS remains the specified component. For standard 22-24 AWG installations, the Molex part provides full compatibility.

Availability: The Molex 1300478008 is in active production status with confirmed inventory availability, whereas the ISPS688FAS is obsolete. Selection of the substitute part ensures supply chain continuity for new installations and ongoing maintenance requirements.

Frequently Asked Questions (FAQ)

Q: Can the Molex 1300478008 be used as a direct replacement for the Panduit ISPS688FAS in existing installations?

A: Yes, for applications using 22-24 AWG wire. The connector types, pin configurations, shielding, and electrical ratings are identical. Physical dimensions are equivalent within manufacturing tolerance. If your installation uses 25-27 AWG wire, the original ISPS688FAS specification must be maintained.

Q: What is the significance of the wire gauge difference between the two parts?

A: The ISPS688FAS accepts 22-27 AWG wire, while the Molex 1300478008 accepts 22-24 AWG wire. This difference reflects IDC contact design variations between manufacturers. For standard Ethernet installations using 22-24 AWG cable, both parts are equivalent. Larger gauge wires (25-27 AWG) require the original Panduit specification.

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

A: The connectors are dimensionally equivalent for practical purposes. The ISPS688FAS measures 2.059" (52.30mm) in length, while the Molex 1300478008 measures 2.055" (52.20mm). This 0.004" variance is within standard manufacturing tolerance and does not affect mechanical fit or performance.

Q: Do both connectors meet the same regulatory and compliance standards?

A: Yes. Both the ISPS688FAS and Molex 1300478008 are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8536.69.8000) classifications. They are equivalent for regulatory and procurement purposes.

Q: What is the difference between the Panduit IndustrialNet™ series and the Molex Brad Micro-Change 130047 series?

A: These are separate product lines from different manufacturers. Both series produce 8p8c shielded modular connectors rated for Cat6a performance. The Molex part is specified as a functional equivalent based on electrical and mechanical parameter matching, not series designation.

Q: Why is the ISPS688FAS listed as obsolete?

A: Obsolete status indicates that Panduit has discontinued production of this component. The Molex 1300478008 is recommended as the active production equivalent to ensure supply chain continuity and support for new installations and maintenance requirements.

Q: Are there any performance differences between gold-plated contacts on these two connectors?

A: Both connectors feature gold-plated contacts with identical finish thickness (31.5µin / 0.80µm). Contact material differs (Phosphor Bronze in the Panduit versus Spring Steel in the Molex), but both materials are standard for IDC connectors and provide equivalent electrical performance at the specified current rating.

Q: Can these connectors be used interchangeably in the same cable assembly?

A: Yes, for applications within the compatible wire gauge range (22-24 AWG). Both connectors conform to the 8p8c (RJ45/Ethernet) standard and are mechanically and electrically interchangeable with standard Ethernet mating connectors and cable assemblies.
