RJSNEJ08DA8 Equivalent & Substitute Parts

Part Overview

The RJSNEJ08DA8 is a modular jack connector manufactured by Amphenol ICC (Commercial Products) designed for 8p8c (RJ45, Ethernet) applications. This connector features a 90° right-angle orientation, unshielded design, and through-hole solder termination. The product is classified as obsolete, necessitating identification of equivalent substitute components for ongoing procurement and system integration requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the RJSNEJ08DA8 are identified based on electrical and mechanical compatibility within the modular connector category. The primary substitution criteria include:

Core Compatibility Parameters:

• Connector type (Jack)
• Contact configuration (8p8c RJ45 Ethernet)
• Mounting methodology (Through Hole)
• Termination approach (Solder)
• Orientation (90° Right Angle)
• Contact material and finish specifications
• Operating temperature envelope
• Regulatory compliance (RoHS)

The RJSNEJ08DA8 is an unshielded variant. Substitute parts may include shielded configurations when the electrical interface requirements permit EMI shielding. Shielded variants provide enhanced electromagnetic interference protection while maintaining mechanical and electrical pin compatibility.

Parameter Comparison

Engineering Selection Recommendations

The RJSNEJ08DA8 is classified as obsolete. The RJSAE538H08 is an active product from the same manufacturer (Amphenol ICC Commercial Products) and serves as the primary equivalent substitute.

Selection Basis:

Both components maintain identical mechanical and electrical pin configurations for 8p8c RJ45 Ethernet applications. Both are RoHS compliant and feature phosphor bronze contacts with gold plating. Both support through-hole solder termination with 90° right-angle orientation.

The RJSAE538H08 provides an extended operating temperature range (-55°C to 85°C versus -40°C to 85°C) and includes shielding with EMI finger protection. The shielded design offers enhanced electromagnetic interference rejection compared to the unshielded RJSNEJ08DA8.

For applications where EMI shielding is not required or where the unshielded characteristic is specifically mandated, the RJSAE538H08 remains mechanically and electrically compatible due to identical pin configuration and contact specifications. The presence of shielding does not prevent functional substitution in unshielded applications.

Frequently Asked Questions (FAQ)

Q: Can the RJSAE538H08 directly replace the RJSNEJ08DA8 in existing designs?

A: Yes. Both connectors share identical 8p8c RJ45 pin configurations, through-hole solder termination, 90° right-angle orientation, and contact material specifications. The mechanical footprint and electrical interface are compatible.

Q: What is the primary difference between these two connectors?

A: The RJSNEJ08DA8 is unshielded, while the RJSAE538H08 includes shielding with an EMI finger. The RJSAE538H08 also provides an extended operating temperature range (-55°C minimum versus -40°C minimum).

Q: Does the shielding on the RJSAE538H08 affect compatibility?

A: No. Shielding is an additive feature that does not alter pin configuration or electrical contact characteristics. The shielded variant is compatible with applications designed for unshielded connectors.

Q: Are both connectors RoHS compliant?

A: Yes. Both the RJSNEJ08DA8 and RJSAE538H08 are RoHS compliant and feature identical moisture sensitivity levels (MSL 1, Unlimited).

Q: What is the contact finish thickness difference?

A: The RJSNEJ08DA8 has a contact finish thickness of 30.0µin (0.76µm), while the RJSAE538H08 has 50.0µin (1.27µm). Both use gold plating over phosphor bronze.

Q: Why is the RJSNEJ08DA8 listed as obsolete?

A: Product obsolescence is determined by the manufacturer. The RJSAE538H08, as an active product, is the recommended substitute for new designs and ongoing procurement.
