Switchcraft 111 Barrel Connector - Equivalent & Substitute Parts

Part Overview

The Switchcraft 111 is a 6.35mm (0.250", 1/4") mono headphone jack connector designed for panel mount applications with solder eyelet termination. This connector is part of the Hi-D® 11* series and serves as a standard interface for audio signal routing in professional and consumer audio equipment. The part remains in active production with 893 units currently in stock.

Substitute parts are identified when they maintain electrical and mechanical compatibility within the barrel connector category while offering alternative termination methods, packaging configurations, or inventory availability that may better suit specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

The Switchcraft 111X qualifies as a direct substitute based on the following alignment of critical parameters:

Electrical Compatibility:

• Identical connector type (Phone Jack), gender (Female), and signal configuration (Mono)
• Matching mating diameter of 6.35mm (0.250", 1/4")
• Identical contact count: 2 Conductors, 2 Contacts
• Equivalent voltage rating (48VDC) and current rating (3 A)
• Matching operating temperature range (-20°C ~ 65°C)

Mechanical Compatibility:

• Same mounting type (Panel Mount)
• Identical panel hole size (0.375" / 9.52mm) and thread size (3/8"-32)
• Both unshielded designs with no internal switches
• Equivalent body materials (Brass) and contact materials (Brass with Tin plating)

Primary Difference: The 111X features solder lug termination instead of solder eyelet termination. This represents a termination method variation rather than a functional incompatibility, allowing the 111X to serve applications where solder lug connection is preferred or required.

Compliance Alignment: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory equivalence.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (Switchcraft 111): Select the 111 when solder eyelet termination is specified in the design or when existing PCB layouts are configured for eyelet connection. The part maintains active product status with established supply availability.

Substitute Selection (Switchcraft 111X): The 111X is electrically and mechanically equivalent and may be selected when solder lug termination is compatible with the application's connection methodology. The 111X offers significantly higher inventory availability (4102 units versus 893 units), making it suitable for high-volume production runs or when supply chain continuity is a priority. Both parts maintain identical compliance certifications (ROHS3, REACH unaffected).

The choice between these parts is determined solely by termination method compatibility and inventory requirements, not by electrical or mechanical performance differences.

Frequently Asked Questions (FAQ)

Q: Can the 111X be used as a direct replacement for the 111 in existing designs?

A: The 111X is electrically and mechanically equivalent to the 111. The only difference is the termination method: the 111 uses solder eyelet termination while the 111X uses solder lug termination. Substitution is possible only if the PCB layout and assembly process can accommodate solder lug connections instead of eyelet connections.

Q: What is the difference between solder eyelet and solder lug termination?

A: Solder eyelet termination features a hole through which wire or PCB traces pass before soldering. Solder lug termination provides a flat tab for surface soldering. The choice depends on the specific assembly method and PCB design.

Q: Are both parts RoHS compliant?

A: Yes. Both the 111 and 111X are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the panel hole size requirement for installation?

A: Both connectors require a 0.375" (9.52mm) panel hole with 3/8"-32 thread size. Installation hardware (nut and washer) is included with both parts.

Q: Can these connectors handle the same voltage and current levels?

A: Yes. Both the 111 and 111X are rated for 48VDC and 3 A maximum current, with identical operating temperature ranges of -20°C to 65°C.

Q: Which part should be selected for high-volume production?

A: The 111X offers significantly higher inventory availability (4102 units in stock compared to 893 units for the 111), making it the preferred choice for high-volume applications when termination method compatibility exists.
