SJ-3513 Equivalent & Substitute Parts

Part Overview

The SJ-3513 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 1136 units in stock.

Substitute parts are identified when they maintain electrical compatibility across critical parameters including connector type, mating diameter, conductor configuration, termination method, and mounting orientation. Alternative models may be required due to inventory availability, packaging preferences, or specific application constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SJ-3513 is determined by strict equivalence across the following critical parameters:

• Connector Type & Gender: Phone Jack, Female
• Mating Diameter: 4.60mm (0.141", 1/8", Mini Plug) - Headphone
• Signal Configuration: Stereo (3 Conductor, TRS)
• Contact Count: 3 Conductors, 3 Contacts
• Mounting Configuration: Panel Mount, Through Hole, Right Angle
• Termination Method: Solder Eyelet(s)
• Electrical Ratings: 12VDC, 1 A minimum
• Temperature Range: -25°C ~ 85°C minimum

The SJ1-3513 meets all substitution criteria as a direct equivalent within the CUI Devices barrel connector portfolio. Both parts share identical functional specifications, electrical ratings, and mechanical interfaces, differing only in packaging format and series designation.

Parameter Comparison

Engineering Selection Recommendations

The SJ1-3513 is a direct functional equivalent to the SJ-3513 for all electrical and mechanical applications. Both parts maintain identical performance characteristics across voltage, current, temperature, and connector specifications.

Selection between these parts should be based on:

• Inventory Availability: SJ1-3513 has significantly higher stock (92403 units) compared to SJ-3513 (1136 units)
• Packaging Requirements: SJ1-3513 is supplied in bulk packaging; SJ-3513 in standard packaging
• Compliance Certification: SJ1-3513 carries explicit ROHS3 compliance documentation
• Series Continuity: SJ-3513 maintains the original SJ series designation; SJ1-3513 uses the SJ1 series

Both parts are manufactured by CUI Devices and are in active production status, ensuring long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can SJ1-3513 be used as a direct replacement for SJ-3513 in existing designs?

A: Yes. The SJ1-3513 meets all electrical and mechanical specifications of the SJ-3513. No circuit modifications or mechanical redesign is required. The connector interface, pin configuration, electrical ratings, and operating temperature range are identical.

Q: What is the difference between SJ-3513 and SJ1-3513?

A: The primary differences are packaging format (standard vs. bulk) and series designation (SJ vs. SJ1). Electrical performance, mechanical dimensions, and connector specifications are equivalent. SJ1-3513 includes explicit ROHS3 compliance certification.

Q: Are there any compatibility concerns with panel mounting?

A: No. Both parts use identical panel mount specifications: 0.236" (5.99mm) panel hole size, M6 thread size, and right-angle through-hole mounting. Installation procedures and mechanical interfaces are interchangeable.

Q: What is the mating plug specification for these connectors?

A: Both connectors accept standard 4.6mm (0.141", 1/8", Mini Plug) stereo headphone plugs with three-conductor (TRS) configuration. The actual diameter tolerance is 0.142" (3.60mm).

Q: Are these connectors shielded?

A: No. Both SJ-3513 and SJ1-3513 are unshielded connectors. For applications requiring electromagnetic interference protection, alternative shielded models must be specified.

Q: What termination method is used?

A: Both connectors use solder eyelet termination for direct PCB mounting. No additional adapters or connectors are required for circuit board integration.
