Key Parameters

Substitute Part Grouping Explanation

Substitution for the SCHURTER 4803.3300 requires matching the following critical parameters:

• Connector Type & Configuration: Female phone jack with 3-conductor stereo (TRS) configuration
• Mating Diameter: 6.35mm (0.250", 1/4") headphone standard
• Electrical Ratings: Minimum 12VAC/DC voltage rating and 2A current capacity
• Termination Method: Solder-type connection for PCB integration
• Contact Material: Gold-plated brass for corrosion resistance and signal integrity
• Environmental Compliance: RoHS3 compliance for regulatory alignment

The provided substitute list contains CEC Industries part number 131, which is classified as a lamp component (G-4.6 / E10 miniature screw base) with a voltage rating of 1.3V. This part does not meet the electrical, mechanical, or functional requirements for substitution of the SCHURTER 4803.3300 stereo phone jack connector.

Parameter Comparison

Engineering Selection Recommendations

No functionally equivalent substitute part is available from the provided substitute list. The CEC Industries 131 is a lamp component and does not serve the connector function of the SCHURTER 4803.3300.

For applications requiring a 6.35mm stereo phone jack connector with solder termination, component selection must prioritize:

• Verification of 6.35mm mating diameter compliance with existing mating plugs
• Confirmation of 3-conductor TRS configuration for stereo signal routing
• Validation of solder termination compatibility with PCB assembly processes
• Confirmation of minimum 12VAC/DC voltage and 2A current ratings
• Verification of RoHS3 compliance for regulatory requirements

Given the obsolete status of the SCHURTER 4803.3300, sourcing from authorized distributors with verified inventory or identifying alternative connector manufacturers with equivalent 6.35mm stereo phone jack specifications is recommended.

Frequently Asked Questions (FAQ)

Q: Why is CEC Industries 131 listed as a substitute if it is not compatible?

A: The provided substitute list contains CEC Industries 131, which is a lamp component. This part does not meet the functional, electrical, or mechanical requirements for substitution of a stereo phone jack connector and should not be used as a replacement.

Q: What are the critical parameters for finding a true substitute for the SCHURTER 4803.3300?

A: A true substitute must match: 6.35mm mating diameter, 3-conductor stereo (TRS) configuration, female gender, solder termination, gold-plated brass contacts, minimum 12VAC/DC voltage rating, 2A current capacity, and RoHS3 compliance.

Q: Can the SCHURTER 4803.3300 be replaced with a different connector type?

A: No. The 6.35mm stereo phone jack is a standardized connector format. Replacement with different connector types would require redesign of mating interfaces and is not a direct substitution.

Q: What does the obsolete status mean for component sourcing?

A: Obsolete status indicates the SCHURTER 4803.3300 is no longer in active production. Sourcing requires identification of remaining inventory from authorized distributors or selection of alternative manufacturers offering equivalent 6.35mm stereo phone jack connectors.

Q: Are there compliance considerations when selecting a substitute?

A: Yes. Any substitute must maintain RoHS3 compliance and meet the same electrical ratings (12VAC/DC, 2A) to ensure regulatory alignment and system performance.
