J8064E64 Equivalent & Substitute Parts

Part Overview

The J8064E64 is a 4-port RJ45 through-hole modular connector from Pulse Electronics' PULSEJACK™ J8 series, designed for 10/100 Base-TX Ethernet applications with AutoMDIX capability. This connector features a 90° right-angle orientation, shielded design with EMI finger protection, and solder termination for PCB mounting.

The J8064E64 carries an obsolete product status. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production or maintenance requirements for systems utilizing this connector.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the J8064E64 is determined by strict equivalence across the following critical parameters:

• Connector type and port configuration (RJ45, 4-port)
• Mounting method and orientation (through-hole, 90° right-angle)
• Electrical application specification (10/100 Base-TX, AutoMDIX)
• Physical dimensions, particularly height above board (0.536" / 13.61mm)
• Shielding architecture (shielded with EMI finger)
• Contact material and finish specifications (phosphor bronze with gold plating)
• Operating temperature range (0°C ~ 70°C)

The J8064E64NL meets all these criteria and qualifies as a direct substitute. The primary distinction between these parts is product status and packaging format, not functional or electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The J8064E64NL is the direct substitute for the obsolete J8064E64. Both parts are electrically and mechanically identical across all functional parameters. Selection of J8064E64NL is supported by the following factors:

• Active product status ensures ongoing availability and supply chain support
• RoHS compliance of J8064E64NL meets current environmental and regulatory requirements, whereas the original J8064E64 does not
• Identical electrical performance for 10/100 Base-TX Ethernet applications
• Identical mechanical fit and PCB integration characteristics
• Tray packaging of J8064E64NL accommodates standard component handling and automated assembly processes

For new designs or production transitions, J8064E64NL is the appropriate selection. For legacy system maintenance where RoHS non-compliance is not a constraint, J8064E64 remains functionally equivalent if available inventory exists.

Frequently Asked Questions (FAQ)

Q: Can J8064E64NL be used as a direct replacement for J8064E64 in existing designs?

A: Yes. The J8064E64NL is electrically and mechanically identical to the J8064E64. All functional parameters, including connector type, port count, orientation, termination method, shielding, and operating temperature range, are equivalent. PCB layout and assembly procedures require no modification.

Q: What is the primary difference between J8064E64 and J8064E64NL?

A: The J8064E64NL is the active production variant with RoHS compliance. The J8064E64 is obsolete and RoHS non-compliant. Packaging differs (tray versus bulk), but electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns when substituting J8064E64NL for J8064E64?

A: No compatibility concerns exist. Both parts conform to the same physical dimensions, electrical specifications, and application requirements for 10/100 Base-TX Ethernet with AutoMDIX functionality.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical performance. Both parts deliver identical electrical characteristics for Ethernet applications.

Q: What packaging formats are available for these parts?

A: J8064E64 is supplied in bulk packaging. J8064E64NL is supplied in tray packaging, which is standard for automated assembly and component handling.

Q: Are both parts suitable for 10/100 Base-TX applications?

A: Yes. Both J8064E64 and J8064E64NL are specified for 10/100 Base-TX Ethernet applications with AutoMDIX capability and operate across the 0°C to 70°C temperature range.
