Switchcraft 3501MC RCA Phono Plug Mono Connector - Equivalent & Substitute Parts

Part Overview

The Switchcraft 3501MC is a barrel connector classified as a Phono (RCA) plug designed for mono audio applications. This connector features a 3.20mm ID, 9.00mm OD (RCA) standard mating diameter with solder termination and free-hanging in-line mounting. The 3501MC is currently listed as obsolete, which necessitates identification of active equivalent parts to maintain supply chain continuity for applications requiring this connector specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3501MC is determined by strict equivalence across the following critical parameters:

• Connector type and gender (Phono RCA Plug, Male)
• Signal configuration (Mono)
• Mating diameter specification (3.20mm ID, 9.00mm OD per RCA standard)
• Contact and conductor count (2 Conductors, 2 Contacts)
• Mounting configuration (Free Hanging In-Line)
• Termination method (Solder)
• Material composition (Copper Alloy body and contacts with Nickel plating)

The 3501MCX meets all substitution criteria as a direct equivalent within the 3501M series. Both parts share identical electrical and mechanical specifications, differing only in product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The 3501MCX is the direct substitute for the obsolete 3501MC. Both connectors are electrically and mechanically identical across all specified parameters. The primary distinction is product status: the 3501MC is obsolete while the 3501MCX is active and currently in production.

An additional consideration is regulatory compliance. The 3501MCX carries ROHS3 compliance certification, whereas the 3501MC is RoHS non-compliant. For applications subject to RoHS requirements, the 3501MCX is the appropriate selection. Both parts maintain identical REACH and ECCN classifications.

The 3501MCX is supplied in bulk packaging, which may differ from the original 3501MC packaging configuration. Verify packaging requirements for your procurement process.

Frequently Asked Questions (FAQ)

Q: Can the 3501MCX be used as a direct replacement for the 3501MC?

A: Yes. The 3501MCX is a direct electrical and mechanical equivalent. Both connectors share identical specifications for connector type, gender, signal configuration, mating diameter, contact count, mounting type, termination method, and material composition.

Q: What is the primary reason to transition from 3501MC to 3501MCX?

A: The 3501MC is obsolete. The 3501MCX is the active equivalent part from Switchcraft Inc. within the 3501M series and maintains full compatibility with applications designed for the 3501MC.

Q: Are there compliance differences between these parts?

A: Yes. The 3501MCX is ROHS3 compliant, while the 3501MC is RoHS non-compliant. Both parts are REACH Unaffected and share the same ECCN and HTSUS classifications. For applications requiring RoHS compliance, the 3501MCX is the appropriate selection.

Q: Does packaging differ between the two parts?

A: The 3501MCX is supplied in bulk packaging. The original 3501MC packaging configuration is not specified in the available data. Confirm packaging requirements with your procurement specifications.

Q: Are the mechanical dimensions identical?

A: Yes. Both the 3501MC and 3501MCX feature the same mating diameter (3.20mm ID, 9.00mm OD per RCA standard) and actual diameter measurements (0.125" / 3.18mm ID, 0.370" / 9.40mm OD).

Q: What materials are used in the 3501MCX?

A: The connector body and contacts are constructed from copper alloy with nickel plating. The connector is unshielded and designed for solder termination in free-hanging in-line applications.
