RJSNEJF8MA8 Equivalent & Substitute Parts

Part Overview

The RJSNEJF8MA8 is a modular jack connector manufactured by Amphenol ICC (Commercial Products), designed for 8p8c (RJ45, Ethernet) applications with 90° right-angle orientation and shielding. This connector features through-hole solder termination, board lock functionality, and dual LED indicators (Red-Yellow). The part is classified as obsolete, necessitating identification of active equivalent components that maintain electrical and mechanical compatibility for ongoing production and field replacement requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RJSNEJF8MA8 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility:

• Contact configuration: 8p8c (RJ45, Ethernet)
• Connector type: Jack
• Termination method: Solder
• Shielding: Shielded

Mechanical Compatibility:

• Orientation: 90° Angle (Right)
• Mounting type: Through Hole
• Housing material: Thermoplastic
• Tab direction: Up and Down

Environmental & Regulatory:

• Operating temperature range must encompass or exceed -40°C ~ 85°C
• RoHS compliance status
• Moisture sensitivity level: 1 (Unlimited)

The RJSAE538708 satisfies all substitution criteria as an active product with identical electrical and mechanical specifications. Differences in LED color (Red-Green vs. Red-Yellow), contact finish thickness (50.0µin vs. 30.0µin), and EMI finger shielding enhancement do not preclude functional substitution within the defined parameter set.

Engineering Selection Recommendations

Primary Substitute: RJSAE538708

The RJSAE538708 is the recommended substitute for the obsolete RJSNEJF8MA8. Selection is based on the following engineering criteria:

Compliance & Availability:

• RJSAE538708 maintains active product status, ensuring long-term availability and supply chain continuity
• Both parts are RoHS Compliant and carry identical regulatory classifications (ECCN: EAR99; HTSUS: 8536.69.4040)
• Moisture Sensitivity Level 1 (Unlimited) is maintained

Electrical & Mechanical Equivalence:

• All critical parameters for 8p8c (RJ45, Ethernet) jack connector functionality are identical
• Through-hole solder termination, 90° right-angle orientation, and board lock features are preserved
• Phosphor bronze contacts with gold finish ensure signal integrity and corrosion resistance

Enhanced Performance Characteristics:

• RJSAE538708 extends operating temperature range to -55°C ~ 85°C, providing broader environmental tolerance
• EMI finger shielding enhancement provides superior electromagnetic interference rejection
• Increased contact finish thickness (50.0µin vs. 30.0µin) enhances durability and contact reliability

LED Indicator Consideration:

• LED color differs (Red-Green vs. Red-Yellow); verify application-specific LED indicator requirements before substitution
• If LED color is functionally critical to the application, alternative solutions must be evaluated

Frequently Asked Questions (FAQ)

Q: Can RJSAE538708 directly replace RJSNEJF8MA8 on existing PCB layouts?

A: Yes. Both connectors share identical mechanical specifications: 90° right-angle orientation, through-hole mounting, and board lock features. PCB footprints and mounting hole patterns are compatible. No layout modifications are required.

Q: What is the significance of the EMI finger in RJSAE538708?

A: The EMI finger provides enhanced shielding effectiveness against electromagnetic interference. This is an enhancement over the base shielded design and does not compromise compatibility. It is functionally transparent to the connector interface.

Q: Does the increased contact finish thickness affect connector performance?

A: The increased contact finish thickness (50.0µin vs. 30.0µin) in RJSAE538708 enhances contact durability and wear resistance without affecting electrical performance. This represents an improvement in long-term reliability.

Q: Why is the operating temperature range different?

A: RJSAE538708 specifies -55°C ~ 85°C, extending the lower temperature limit by 15°C compared to RJSNEJF8MA8 (-40°C ~ 85°C). This provides broader environmental tolerance and is fully backward compatible for applications within the original -40°C ~ 85°C range.

Q: Is LED color difference a substitution barrier?

A: LED color difference (Red-Green vs. Red-Yellow) is a visual indicator distinction only. If the application requires specific LED color for status indication or user interface purposes, this difference must be evaluated against functional requirements. If LED color is not functionally critical, substitution proceeds without restriction.

Q: What packaging differences exist between these parts?

A: RJSNEJF8MA8 packaging is not specified in available data. RJSAE538708 is supplied in Tray packaging. Confirm packaging requirements with procurement specifications before ordering.

Q: Are both parts from the same manufacturer?

A: Yes. Both RJSNEJF8MA8 and RJSAE538708 are manufactured by Amphenol ICC (Commercial Products), ensuring consistent quality standards and design philosophy.

Q: What is the inventory status for substitution planning?

A: RJSNEJF8MA8 is obsolete with 961 pcs in current stock. RJSAE538708 is active with 1084 pcs in current stock, providing reliable long-term supply availability for new designs and field replacements.
