SJ-3554NG Equivalent & Substitute Parts

Part Overview

The SJ-3554NG is a 4.6mm stereo barrel connector (phone jack) manufactured by CUI Devices, designed for headphone and audio applications. This right-angle, through-hole mounted connector features a kinked pin termination and supports stereo (3-conductor, TRS) signal configuration. The part is currently in active production with 1079 units available in inventory.

Substitute parts are identified when they maintain identical electrical specifications, mechanical compatibility, and connector geometry while potentially offering different packaging or availability options.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SJ-3554NG is determined by strict adherence to the following parameters:

• Connector type and gender (Phone Jack, Female)
• Mating diameter specification (4.60mm)
• Signal configuration (Stereo, 3-conductor TRS)
• Contact count (3 Conductors, 4 Contacts)
• Mounting configuration (Through Hole, Right Angle)
• Termination method (Kinked Pin)
• Electrical ratings (12VDC, 1A)
• Operating temperature range (-25°C ~ 85°C)
• Contact and housing materials (Brass/Copper with Tin plating, PBT housing)

The SJ1-3554NG qualifies as a direct substitute because it maintains all critical electrical and mechanical parameters while differing only in packaging format and series designation.

Parameter Comparison

Engineering Selection Recommendations

Both the SJ-3554NG and SJ1-3554NG are active production parts from CUI Devices with identical electrical and mechanical specifications. Selection between these parts should be based on:

• Packaging requirements: The SJ1-3554NG is supplied in bag packaging, while the SJ-3554NG packaging format is not specified.
• Inventory availability: The SJ1-3554NG offers significantly higher stock levels (5484 units versus 1079 units), providing better supply chain continuity.
• Series designation: Both parts belong to the SJ series family and are functionally interchangeable in applications requiring 4.6mm stereo phone jack connectors.

Both parts comply with RoHS3 and REACH regulations, confirming environmental compliance for industrial and consumer applications.

Frequently Asked Questions (FAQ)

Q: Can the SJ1-3554NG be used as a direct replacement for the SJ-3554NG?

A: Yes. Both parts maintain identical electrical ratings (12VDC, 1A), mechanical configuration (4.6mm stereo, right-angle through-hole), and contact specifications (3 conductors, 4 contacts). The parts are functionally equivalent in all applications.

Q: What is the difference between the SJ-3554NG and SJ1-3554NG?

A: The primary differences are packaging format (bag for SJ1-3554NG) and inventory availability. All electrical and mechanical parameters are identical.

Q: Are there any compatibility concerns when substituting between these parts?

A: No compatibility concerns exist. Both connectors feature identical mating diameter (4.60mm), termination style (kinked pin), and mounting configuration (through-hole, right angle). PCB layout and mechanical mounting are interchangeable.

Q: What applications are these connectors suitable for?

A: These 4.6mm stereo phone jack connectors are designed for headphone applications, audio equipment, and consumer electronics requiring standard mini-plug connectivity with TRS (tip-ring-sleeve) signal configuration.

Q: What are the environmental compliance certifications?

A: Both parts are RoHS3 compliant and REACH unaffected, meeting current environmental regulations for industrial and consumer applications.
