SJ-3515 Equivalent & Substitute Parts Reference

Part Overview

The SJ-3515 is a 4.6mm stereo barrel connector (phone jack) manufactured by CUI Devices, designed for headphone and audio applications. This right-angle, panel-mount connector features three conductors (TRS configuration) with solder eyelet termination. The part is currently in active production with 705 units in stock.

Identifying equivalent and substitute parts is necessary when the primary part number becomes unavailable, when alternative packaging formats are required, or when sourcing from different inventory locations is needed to meet project timelines and supply chain requirements.

Key Parameters

Substitute Part Grouping Explanation

The SJ1-3515 qualifies as a direct substitute for the SJ-3515 based on the following critical parameters:

• Connector Type & Signal Configuration: Both parts are stereo phone jacks with identical 3-conductor TRS configuration
• Mating Diameter: Both use the standard 4.60mm (0.141") mini plug interface
• Contact Count: Both feature 3 conductors and 5 contacts
• Mounting & Termination: Both are panel-mount, through-hole, right-angle connectors with solder eyelet termination
• Electrical Ratings: Both support 12VDC at 1A current capacity
• Temperature Range: Both operate across -25°C ~ 85°C
• Compliance: Both are ROHS3 compliant

The primary difference is packaging format: SJ1-3515 is supplied in trays with significantly higher inventory availability (30,280 units), while SJ-3515 uses standard packaging with lower stock levels.

Parameter Comparison

Engineering Selection Recommendations

Both the SJ-3515 and SJ1-3515 are active production parts from CUI Devices with identical electrical and mechanical specifications. Selection between these parts should be based on:

Packaging Requirements: The SJ1-3515 is supplied in tray packaging, which is standard for high-volume manufacturing and automated assembly processes. The SJ-3515 uses standard packaging suitable for lower-volume applications.

Supply Chain Availability: The SJ1-3515 maintains significantly higher inventory levels (30,280 units versus 705 units), making it the preferred choice for projects requiring extended lead time assurance or bulk quantities.

Compliance Status: Both parts meet ROHS3 compliance requirements and are suitable for applications subject to environmental regulations.

Electrical Performance: No performance differentiation exists between these parts. Both are rated for identical voltage (12VDC), current (1A), and temperature ranges (-25°C ~ 85°C).

Frequently Asked Questions (FAQ)

Q: Can SJ1-3515 be used as a direct replacement for SJ-3515?

A: Yes. Both parts are electrically and mechanically identical. The SJ1-3515 is a direct substitute with the only difference being tray packaging versus standard packaging.

Q: What determines compatibility between these connector models?

A: Compatibility is determined by matching the mating diameter (4.60mm), signal configuration (stereo TRS), contact count (3 conductors, 5 contacts), mounting type (panel mount, right angle), and termination method (solder eyelet). Both parts meet all these criteria.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (tray versus standard) does not affect the connector's electrical characteristics, mechanical fit, or performance in the application.

Q: Are there any compliance differences between these parts?

A: No. Both parts carry identical ROHS3 compliance certification and are suitable for the same regulatory environments.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on packaging requirements and supply chain considerations. The SJ1-3515 is recommended when tray packaging is compatible with manufacturing processes or when higher inventory availability is beneficial.
