Switchcraft 389 Circular Connector Adapter - Equivalent & Substitute Parts

Part Overview

The Switchcraft 389 is a circular connector adapter designed to convert between two 3-position XLR female socket interfaces in a free-hanging (in-line) configuration. This adapter features a shielded design with push-pull detent lock fastening and is constructed from zinc die-cast housing with nickel finish.

The 389 is classified as obsolete. Locating equivalent substitute parts is necessary for applications requiring this specific connector interface configuration, particularly where inventory of the original part is limited or unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Switchcraft 389 is determined by the following critical parameters:

• Connector interface type: 3-position XLR female sockets on both ends
• Mounting configuration: Free-hanging (in-line) orientation
• Fastening mechanism: Push-pull detent lock
• Housing construction: Zinc die-cast with nickel finish
• Shielding requirement: Shielded design
• Manufacturer series: Q-G® series

The substitute part 389X maintains identical electrical and mechanical specifications across all these parameters, ensuring direct functional equivalence for applications requiring this adapter configuration.

Parameter Comparison

Engineering Selection Recommendations

The Switchcraft 389X serves as the direct substitute for the obsolete 389 model. Both parts are manufactured by Switchcraft Inc. within the Q-G® series and maintain identical mechanical and electrical interface specifications.

The 389X offers the advantage of active product status, ensuring ongoing availability and supply chain reliability. Additionally, the 389X achieves ROHS3 compliance, whereas the original 389 is non-compliant with RoHS regulations. For applications subject to RoHS requirements or environmental compliance mandates, the 389X is the appropriate selection.

Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.4020) classifications, confirming equivalent regulatory treatment for export and tariff purposes.

Frequently Asked Questions (FAQ)

Q: Is the 389X a direct replacement for the 389?

A: Yes. The 389X maintains identical specifications for connector interface type, mounting configuration, fastening mechanism, housing construction, and shielding. Both parts are 3-position XLR female-to-female adapters in free-hanging configuration with push-pull detent lock fastening.

Q: What is the primary difference between the 389 and 389X?

A: The 389X is the active production variant with ROHS3 compliance, whereas the 389 is obsolete and RoHS non-compliant. The 389X is supplied in bulk packaging.

Q: Can the 389X be used in applications originally designed for the 389?

A: Yes. The electrical and mechanical parameters are identical, ensuring functional equivalence in all applications requiring a 3-position XLR female-to-female adapter with the specified fastening and shielding characteristics.

Q: Are there any compliance considerations when substituting the 389X for the 389?

A: The 389X provides improved compliance status through ROHS3 certification. Applications subject to RoHS regulations should transition to the 389X. Both parts maintain identical ECCN and HTSUS classifications.

Q: What packaging options are available?

A: The 389 was supplied with unspecified packaging. The 389X is available in bulk packaging.
