Switchcraft 111PC Barrel Connector - Equivalent & Substitute Parts

Part Overview

The Switchcraft 111PC is a 6.35mm (0.250", 1/4") mono headphone jack connector designed for panel mount, through-hole solder applications. This connector is part of the Hi-D® 11* series and serves as a standard audio interface component in professional and consumer audio equipment. The 111PC is currently in active production with 646 units available in new original stock. Substitute parts become necessary when addressing specific packaging requirements, inventory constraints, or application-specific mounting configurations while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

The Switchcraft 111PCX qualifies as a direct substitute for the 111PC based on identical electrical and mechanical parameters. Both connectors share the same core specifications: 6.35mm mono phone jack configuration, 2-contact solder termination, panel mount through-hole design, 48VDC voltage rating, 3A current capacity, and -20°C to 65°C operating temperature range. The primary distinction between these parts is packaging format: the 111PC is supplied in standard packaging, while the 111PCX is supplied in bulk packaging. This substitution relationship is valid when application requirements and PCB layout specifications remain unchanged. Both parts are manufactured by Switchcraft Inc. within the Hi-D® 11* series and maintain identical contact material (brass with tin plating), body material (brass), and mechanical mounting specifications including panel hole size (0.375") and thread size (3/8"-32).

Parameter Comparison

Engineering Selection Recommendations

Both the 111PC and 111PCX are active production components manufactured by Switchcraft Inc. and maintain full ROHS3 compliance. Selection between these parts should be based on packaging and inventory requirements rather than electrical or mechanical performance, as both components are functionally identical. The 111PCX offers significantly higher stock availability (11,070 units) compared to the 111PC (646 units), making it suitable for high-volume production runs or applications requiring extended supply chain security. The bulk packaging format of the 111PCX may provide cost advantages for large-scale manufacturing operations. Both parts are suitable for audio interface applications operating within the specified -20°C to 65°C temperature range and 48VDC maximum voltage environment.

Frequently Asked Questions (FAQ)

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

A: Yes. The 111PCX is electrically and mechanically identical to the 111PC. Both connectors feature the same 6.35mm mono jack configuration, 2-contact solder termination, panel mount specifications, and electrical ratings. The only difference is packaging format.

Q: What is the primary difference between the 111PC and 111PCX?

A: The 111PC is supplied in standard packaging, while the 111PCX is supplied in bulk packaging. This distinction affects inventory management and cost per unit for high-volume applications but does not impact connector performance or compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both the 111PC and 111PCX are ROHS3 compliant and suitable for applications requiring environmental compliance certification.

Q: What are the mechanical mounting requirements for these connectors?

A: Both connectors require a 0.375" (9.52mm) panel hole and use a 3/8"-32 thread size for panel mount, through-hole installation. Each connector includes mounting hardware consisting of one connector body, one nut, and one washer.

Q: Can these connectors be used in temperature-sensitive applications?

A: Both the 111PC and 111PCX are rated for operation between -20°C and 65°C. Applications requiring operation outside this range require alternative connector selection.

Q: What is the maximum voltage and current these connectors can handle?

A: Both connectors are rated for 48VDC maximum voltage and 3A maximum current. Applications exceeding these specifications require alternative components.
