Key Parameters

Substitute Part Grouping Explanation

The SJ-63062B qualifies as a direct substitute for the SN70C12A based on the following critical parameters:

Matching Parameters:

• Connector Type: Phone Jack (Female)
• Signal Configuration: Mono (2 Conductors, 3 Contacts)
• Mating Diameter: 6.35mm (0.250", 1/4") headphone standard
• Mounting Configuration: Through Hole, Right Angle
• Termination Method: Solder
• Shielding: Unshielded
• Internal Switch: Single Switch
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected

Functional Equivalence: Both connectors maintain identical electrical and mechanical interfaces for 6.35mm mono audio jack applications. The SJ-63062B is manufactured by CUI Devices and carries active product status, ensuring ongoing availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

The SJ-63062B is the qualified substitute for the obsolete SN70C12A. Selection is based on:

Product Status: The SN70C12A is obsolete, while the SJ-63062B maintains active product status, ensuring long-term availability and supply chain reliability.

Regulatory Compliance: Both components are ROHS3 Compliant and REACH Unaffected, meeting current environmental and safety standards.

Electrical and Mechanical Compatibility: Both connectors maintain identical functional specifications for 6.35mm mono audio jack applications, including connector type, gender, signal configuration, mounting method, and termination approach.

Material Differences: The SJ-63062B uses silver-plated phosphor bronze contacts and PBT housing, compared to the SN70C12A's nickel-plated brass contacts and thermoplastic housing. These material variations do not affect functional compatibility for standard audio jack applications.

Thread Size Variation: The SN70C12A uses 3/8"-32 threading, while the SJ-63062B uses M12 metric threading. Panel mounting hardware must be selected accordingly for the substitute component.

Frequently Asked Questions (FAQ)

Q: Can the SJ-63062B directly replace the SN70C12A in existing designs?

A: Yes. Both connectors share identical electrical and mechanical interfaces for 6.35mm mono audio jack applications. The primary consideration is panel mounting hardware compatibility due to different thread sizes (3/8"-32 versus M12).

Q: What are the key differences between these two connectors?

A: The primary differences are contact material plating (nickel versus silver), base contact material (brass versus phosphor bronze), housing material (thermoplastic versus PBT), and thread size (3/8"-32 versus M12). These variations do not affect electrical performance for standard audio applications.

Q: Why is the SJ-63062B recommended over other 6.35mm connectors?

A: The SJ-63062B matches all critical substitution parameters: connector type, gender, signal configuration, mating diameter, contact count, mounting method, and termination approach. It maintains active product status and full regulatory compliance.

Q: Are there any compatibility concerns with the different thread sizes?

A: The thread size difference (3/8"-32 versus M12) requires appropriate panel mounting hardware selection. The electrical and mechanical connector interfaces remain fully compatible.

Q: What is the inventory status of these components?

A: The SN70C12A has 777 pieces in stock as new original inventory. The SJ-63062B has 1143 pieces in stock as new original inventory.
