Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCHURTER 4803.1300 is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Mating diameter: 6.35mm (0.250", 1/4") headphone standard
• Connector type: Phone Plug, Male gender
• Signal configuration: Stereo (3 Conductor, TRS)
• Termination method: Solder
• Mounting style: Free Hanging (In-Line)
• Contact material: Brass with nickel plating
• Number of contacts: 3 Conductors, 3 Contacts

Allowable Variations:

• Actual diameter tolerance: 0.248" to 0.250" (6.30mm to 6.35mm)
• Operating temperature range: Must encompass or exceed -20°C to 70°C
• Voltage rating: Must meet or exceed 12VAC/DC
• Current rating: Must meet or exceed 2A
• Shielding: May differ based on application requirements
• Body color: May vary (silver acceptable)
• Compliance certifications: ROHS3 and REACH status maintained

The CUI Devices SP-6330B qualifies as a substitute based on matching all critical parameters while maintaining full electrical and mechanical compatibility with the SCHURTER 4803.1300.

Parameter Comparison

Engineering Selection Recommendations

The CUI Devices SP-6330B serves as a direct substitute for the obsolete SCHURTER 4803.1300 in applications requiring 6.35mm stereo phone plug connectors with solder termination. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing and deployment.

The SP-6330B operates across an extended lower temperature range (-25°C versus -20°C), providing enhanced performance in cold environments. The substitute features shielding, which offers improved noise immunity compared to the unshielded original design. The current rating of the SP-6330B is 1A, which is lower than the original 2A specification; therefore, applications requiring the full 2A capacity must be evaluated for current draw compatibility before substitution.

Both connectors utilize identical 6.35mm mating diameter standards, brass bodies with nickel-plated contacts, and solder termination methods, ensuring mechanical and electrical interchangeability within the specified parameter tolerances.

Frequently Asked Questions (FAQ)

Q: Can the CUI Devices SP-6330B replace the SCHURTER 4803.1300 in all applications?

A: The SP-6330B is mechanically and electrically compatible for applications drawing 1A or less. Applications requiring the full 2A current capacity of the original connector must be evaluated separately, as the substitute is rated for 1A maximum.

Q: What is the significance of the shielding difference between these connectors?

A: The SCHURTER 4803.1300 is unshielded, while the CUI Devices SP-6330B includes shielding. Shielding reduces electromagnetic interference and noise in audio signal paths. Applications sensitive to noise may benefit from the shielded design, while unshielded applications remain compatible with the shielded substitute.

Q: Are the physical dimensions compatible for direct board-level replacement?

A: Both connectors feature 6.35mm mating diameters and free-hanging in-line mounting. The mating depth differs slightly (1.210" versus 1.220"), representing a 0.010" variation within typical mechanical tolerances. Physical fit compatibility should be confirmed for space-constrained applications.

Q: Do both connectors meet current regulatory requirements?

A: Yes. Both the SCHURTER 4803.1300 and CUI Devices SP-6330B are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component manufacturing and deployment.

Q: What is the cable opening difference, and does it affect compatibility?

A: The SCHURTER 4803.1300 has a 0.268" (6.80mm) cable opening, while the SP-6330B has a 0.315" (8.00mm) opening. The larger opening on the substitute accommodates thicker cable jackets. Existing cable assemblies designed for the original connector remain compatible, though the substitute provides greater flexibility for cable diameter variations.

Q: Why is the SCHURTER 4803.1300 classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The CUI Devices SP-6330B provides functional equivalence for new designs and replacement applications where this connector category is required.
