Key Parameters

Substitute Part Grouping Explanation

Substitution of the FC68125 is determined by strict alignment of the following critical parameters:

Mechanical Compatibility:

• Connector type must be Phone Jack (female gender)
• Mating diameter must be 3.50mm (0.141", 1/8", Mini Plug) - Headphone specification
• Mounting configuration must be Through Hole, Right Angle
• Termination method must be Solder

Electrical Compatibility:

• Signal configuration must be Stereo (4 Conductor, TRRS)
• Number of contacts must be 4 Conductors, 4 Contacts
• Internal switch requirement must be Does Not Contain Switch
• Shielding must be Unshielded

Regulatory Compliance:

• RoHS3 Compliant status required
• REACH Unaffected status required
• Moisture Sensitivity Level must be 1 (Unlimited)

The substitute part SJ-43514 meets all mandatory mechanical, electrical, and regulatory criteria for direct substitution with the FC68125.

Parameter Comparison

Engineering Selection Recommendations

Both the FC68125 and SJ-43514 are active production parts with full regulatory compliance. The FC68125 is manufactured by CLIFF Electronic Components Ltd and the SJ-43514 is manufactured by CUI Devices. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings.

Selection between these parts should be based on:

Availability: The SJ-43514 has significantly higher inventory (108,928 units) compared to the FC68125 (981 units), making it the preferred choice for high-volume applications or when immediate availability is critical.

Packaging: The FC68125 is supplied in bag packaging, while the SJ-43514 is supplied in tray packaging. Tray packaging is standard for automated assembly processes.

Electrical Specifications: The SJ-43514 provides rated electrical specifications (12VDC, 1A maximum current) and mating length/depth (0.551" / 14.00mm), which are not specified for the FC68125. These specifications do not restrict substitution but provide additional design reference data for the SJ-43514.

Contact Materials: The SJ-43514 specifies gold and tin plating on copper alloy and phosphor bronze contacts with polyamide (PA66) nylon 6/6 housing material. These material specifications ensure reliable long-term performance in audio applications.

Both parts are suitable for direct substitution in 3.5mm stereo jack applications requiring 4-conductor TRRS connectivity with through-hole right-angle solder termination.

Frequently Asked Questions (FAQ)

Q: Can the SJ-43514 be used as a direct replacement for the FC68125?

A: Yes. Both parts meet identical mechanical, electrical, and regulatory requirements. The SJ-43514 is a direct substitute for the FC68125 in all applications requiring a 3.5mm 4-pole stereo phone jack with through-hole right-angle solder termination.

Q: What are the key compatibility criteria for substituting these parts?

A: Substitution is valid when the following parameters match: connector type (Phone Jack), gender (Female), mating diameter (3.50mm headphone), signal configuration (Stereo 4-Conductor TRRS), mounting type (Through Hole Right Angle), termination method (Solder), shielding (Unshielded), and regulatory compliance (ROHS3, REACH Unaffected, MSL 1).

Q: Are there differences in packaging between these parts?

A: Yes. The FC68125 is packaged in bags with 981 units in stock, while the SJ-43514 is packaged in trays with 108,928 units in stock. Tray packaging is standard for automated assembly and pick-and-place operations.

Q: Does the SJ-43514 provide additional electrical specifications?

A: The SJ-43514 specifies operating temperature range (-20°C to 85°C), rated voltage (12VDC), and maximum current (1A). The FC68125 does not provide these specifications in the available data. These specifications do not affect substitution compatibility.

Q: What materials are used in the SJ-43514 construction?

A: The SJ-43514 uses copper alloy and phosphor bronze contacts with gold and tin plating. The housing is constructed from polyamide (PA66) nylon 6/6 material. These materials ensure durability and reliable electrical performance in audio connector applications.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the FC68125 and SJ-43514 are ROHS3 compliant and REACH unaffected. Both carry MSL 1 (Unlimited) moisture sensitivity ratings, indicating no moisture sensitivity restrictions during storage or handling.

Q: What is the mating length/depth of these connectors?

A: The SJ-43514 specifies a mating length/depth of 0.551" (14.00mm). This specification is not provided for the FC68125 in the available data.
