TT263 Equivalent & Substitute Parts Reference

Part Overview

The Switchcraft TT263 is a 4.39mm (0.173") phone plug connector featuring twin stereo (3-conductor, TRS) configuration with screw termination. This connector is classified as obsolete, necessitating identification of equivalent substitute parts for ongoing applications requiring twin stereo audio connectivity. The TT263 provides dual stereo signal paths with six total contacts (2 sets of 3 conductors) in a free-hanging, in-line mounting configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TT263 is determined by the following critical parameters:

• Connector type classification (Phone Plug, Twin stereo configuration)
• Mating diameter (4.39mm / 0.173")
• Signal line configuration (3-conductor TRS stereo per plug set)
• Contact count (6 total contacts in dual stereo arrangement)
• Termination method (screw-based)
• Mounting configuration (free-hanging, in-line)
• Regulatory compliance (ROHS3, REACH status)

The substitute part TT263Z is classified as a stereo twin connector from Switchcraft Inc. with active product status and identical regulatory compliance certifications (ROHS3 Compliant, REACH Unaffected). Both parts share the same manufacturer, category classification, and compliance framework, establishing functional equivalence for applications requiring twin stereo audio connectivity.

Parameter Comparison

Engineering Selection Recommendations

The TT263Z represents an active-status equivalent for the obsolete TT263. Both components maintain identical regulatory compliance profiles under ROHS3 and REACH frameworks, with matching export classification (EAR99) and tariff codes (8536.69.8000). The transition from TT263 to TT263Z is supported by both parts' classification within the barrel connector category and their shared manufacturer lineage from Switchcraft Inc.

Selection between these parts should be based on application-specific requirements for connector geometry, contact configuration, and termination methodology. The TT263Z's active product status ensures continued availability and manufacturing support, whereas the TT263 is subject to obsolescence constraints.

Frequently Asked Questions (FAQ)

Q: What defines the substitution relationship between TT263 and TT263Z?

A: Both parts are twin stereo phone plug connectors manufactured by Switchcraft Inc. with identical regulatory compliance certifications (ROHS3 Compliant, REACH Unaffected). The TT263Z maintains active product status, making it the preferred selection for new applications where the TT263 (obsolete) is no longer available.

Q: Are the physical dimensions identical between TT263 and TT263Z?

A: The provided specifications confirm both parts operate within the 4.39mm (0.173") mating diameter classification for twin stereo connectors. Detailed dimensional data beyond the mating diameter and mating length/depth (0.865" / 21.97mm) for the TT263 is not provided for the TT263Z; physical verification is necessary for applications with strict dimensional constraints.

Q: Can TT263Z be used as a direct replacement in existing TT263 applications?

A: Both parts share identical manufacturer origin, connector classification (twin stereo), and regulatory compliance status. Substitution feasibility depends on matching the specific contact configuration, termination method (screw-based), and mounting requirements (free-hanging, in-line) of the original application.

Q: What is the inventory availability difference between these parts?

A: The TT263 has 736 pieces in stock (obsolete status), while the TT263Z has 947 pieces available (active status). For long-term supply chain planning, the TT263Z's active classification provides greater assurance of continued availability.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are ROHS3 Compliant, REACH Unaffected, classified under EAR99 export control, and share the identical HTSUS tariff code (8536.69.8000), indicating equivalent regulatory treatment.
