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

Part Overview

The Switchcraft 3501M 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 2 conductors and 2 contacts. The 3501M is terminated via solder and is mounted as a free-hanging in-line connector with nickel-plated copper alloy contacts.

The 3501M carries an obsolete product status. Locating equivalent or substitute components is necessary for applications requiring continued supply, maintenance, or system upgrades where this connector type remains functionally appropriate.

Key Parameters

Substitute Part Grouping Explanation

The 3501MX qualifies as a direct substitute for the 3501M based on the following critical parameters:

• Connector Type: Both are Phono (RCA) Plugs
• Gender: Both are Male
• Signal Lines: Both are Mono
• Mating Diameter: Both conform to 3.20mm ID, 9.00mm OD (RCA) standard
• Number of Contacts: Both have 2 Conductors, 2 Contacts
• Mounting Type: Both are Free Hanging (In-Line)
• Termination: Both use Solder
• Shielding: Both are Unshielded
• Contact Material: Both use Copper Alloy with Nickel Plating
• Body Material: Both use Copper Alloy
• Body Color: Both are Silver
• Internal Switch: Neither contains a switch

The 3501MX maintains full mechanical and electrical compatibility with the 3501M while offering improved product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The 3501MX is the appropriate substitute for the obsolete 3501M. Both connectors share identical mechanical and electrical specifications for the critical parameters that define RCA phono plug mono connector functionality: mating diameter, contact configuration, termination method, and material composition.

The 3501MX offers two distinct advantages:

1. Active Product Status: The 3501MX maintains current manufacturing and supply availability, whereas the 3501M is obsolete.

2. Regulatory Compliance: The 3501MX is ROHS3 compliant, meeting current environmental and material restriction standards. The 3501M is RoHS non-compliant.

Both connectors maintain identical REACH and ECCN classifications. The cable opening dimension shows a minor variation (0.127" versus 0.130"), which remains within acceptable tolerance for standard cable jacket diameters in this connector class.

Frequently Asked Questions (FAQ)

Q: Can the 3501MX directly replace the 3501M in existing applications?

A: Yes. The 3501MX maintains full mechanical and electrical compatibility with the 3501M. Both connectors conform to the same RCA phono plug standard with identical mating diameters, contact configurations, and solder termination specifications.

Q: What is the significance of the product status difference?

A: The 3501M is classified as obsolete, indicating discontinued manufacturing. The 3501MX is active, meaning it is currently manufactured and available for procurement. For new designs or ongoing supply requirements, the 3501MX is the appropriate selection.

Q: Does the RoHS compliance difference affect compatibility?

A: No. RoHS compliance is a regulatory and material composition classification. It does not affect the electrical or mechanical performance of the connector. The 3501MX's ROHS3 compliance makes it suitable for applications subject to environmental regulations, whereas the 3501M's non-compliance may restrict its use in regulated markets.

Q: Are there differences in cable opening dimensions?

A: The 3501M has a cable opening of 0.127" (3.23mm), while the 3501MX has 0.130" (3.30mm). This minor variation accommodates standard cable jacket tolerances and does not affect functional compatibility.

Q: What packaging options are available?

A: The 3501M packaging specification is not provided. The 3501MX is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Are both connectors available in current inventory?

A: The 3501M has 1093 pieces in stock. The 3501MX has 5174 pieces in stock. Availability may vary by distributor and time of order.
