TRAPC3M1 Equivalent & Substitute Parts

Part Overview

The TRAPC3M1 is a 3-position circular connector receptacle with male pins, manufactured by Switchcraft Inc. as part of the Tini Q-G® TRAPC series. This Mini XLR connector is designed for through-hole, right-angle mounting with solder termination, rated for 5A current, and is commonly used in audio, medical, and testing equipment applications.

The TRAPC3M1 carries an obsolete product status. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support legacy system maintenance and repairs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TRAPC3M1 is determined by strict equivalence across the following critical parameters:

• Connector type and pin configuration (Receptacle, Male Pins, 3-position)
• Shell size and form factor (Mini XLR)
• Mounting configuration (Through Hole, Right Angle)
• Termination method (Solder)
• Electrical rating (5A current capacity)
• Contact material and finish (Brass with Tin plating)
• Mechanical fastening (Latch Lock)
• Keyed orientation for polarization

The TRAPC3MSX meets all these criteria and is classified as a direct substitute. The primary distinction is the addition of a bulkhead mounting feature (front side nut) on the TRAPC3MSX, which provides an alternative mounting configuration while maintaining full electrical and mechanical compatibility with the base TRAPC3 platform.

Parameter Comparison

Engineering Selection Recommendations

The TRAPC3MSX is the active substitute for the obsolete TRAPC3M1. Both connectors share identical electrical and mechanical specifications within the Mini XLR 3-position circular connector category.

The TRAPC3MSX offers two significant advantages:

1. Active product status ensures ongoing manufacturer support, documentation, and supply chain availability.
2. ROHS3 compliance satisfies current regulatory requirements, whereas the TRAPC3M1 is RoHS non-compliant.

The addition of bulkhead mounting capability on the TRAPC3MSX provides design flexibility for panel-mount applications while maintaining full backward compatibility with through-hole PCB mounting configurations. Selection between these parts should be based on regulatory compliance requirements and application-specific mounting needs.

Frequently Asked Questions (FAQ)

Q: Can the TRAPC3MSX be used as a direct replacement for the TRAPC3M1 in existing designs?

A: Yes. Both connectors are electrically and mechanically equivalent within the Mini XLR 3-position circular connector specification. The TRAPC3MSX includes an additional bulkhead mounting feature that does not interfere with standard through-hole PCB mounting.

Q: What is the significance of the bulkhead mounting feature on the TRAPC3MSX?

A: The bulkhead front side nut allows the TRAPC3MSX to be mounted directly to a panel or enclosure wall, in addition to standard through-hole PCB mounting. This feature provides design flexibility without affecting electrical performance or pin compatibility.

Q: Why is RoHS compliance important for this substitution?

A: The TRAPC3M1 is RoHS non-compliant, while the TRAPC3MSX is ROHS3 compliant. For new designs or applications subject to RoHS regulations, the TRAPC3MSX is the required choice. For legacy system repairs using existing TRAPC3M1 inventory, compliance status depends on application jurisdiction and customer requirements.

Q: Are there any differences in current rating or electrical performance between these parts?

A: No. Both connectors are rated for 5A current capacity and share identical contact material (brass with tin plating), shell material (thermoplastic), and electrical specifications.

Q: What packaging options are available?

A: The TRAPC3M1 packaging is not specified in available documentation. The TRAPC3MSX is supplied in bulk packaging. Confirm packaging requirements with your procurement department.

Q: How do the inventory levels compare?

A: The TRAPC3M1 has 672 pieces in stock, while the TRAPC3MSX has 4492 pieces available. The higher inventory level for the active TRAPC3MSX reflects its current production status.
