Switchcraft L112B Barrel Connector - Equivalent & Substitute Parts

Part Overview

The Switchcraft L112B is a 6.35mm (0.250", 1/4") stereo headphone jack connector designed for panel mount applications. This connector features a 3-conductor TRS (Tip-Ring-Sleeve) configuration with solder eyelet termination, commonly used in audio equipment, telecommunications, and instrumentation applications. The L112B is part of the Hi-D JAX® L11 series and is currently in active production status with 936 units available in new original stock.

Identifying equivalent and substitute parts is necessary when the primary part number is unavailable, when bulk packaging is required, or when alternative sourcing is needed to optimize procurement timelines and inventory management.

Key Parameters

Substitute Part Grouping Explanation

The L112B and its substitute L112BX are functionally equivalent based on the following critical parameters that determine substitutability:

Electrical Parameters:

• Identical mating diameter: 6.35mm (0.250", 1/4")
• Identical signal configuration: Stereo (3 Conductor, TRS)
• Identical contact count: 3 Conductors, 3 Contacts
• Identical voltage and current ratings: 48VDC, 250 mA

Mechanical Parameters:

• Identical connector type: Phone Jack (Female)
• Identical mounting type: Panel Mount
• Identical termination method: Solder Eyelet(s)
• Identical operating temperature range: -20°C ~ 65°C
• Same series designation: Hi-D JAX® L11

Primary Difference: The L112BX is supplied in bulk packaging, whereas the L112B packaging specification is not detailed. Both parts are manufactured by Switchcraft Inc. and maintain active product status.

Parameter Comparison

Engineering Selection Recommendations

Both the L112B and L112BX are active products manufactured by Switchcraft Inc. and are electrically and mechanically equivalent for all panel mount stereo headphone jack applications requiring 6.35mm TRS connectors.

The L112BX is ROHS3 compliant and carries explicit regulatory certification. Selection between these parts should be based on:

• Packaging requirements: L112BX is supplied in bulk packaging, suitable for high-volume production runs
• Inventory availability: L112BX has significantly higher stock levels (10183 units vs. 936 units)
• Regulatory compliance documentation: L112BX includes explicit ROHS3 compliance certification

Both parts are suitable for applications operating within the -20°C to 65°C temperature range and rated for 48VDC at 250 mA maximum current.

Frequently Asked Questions (FAQ)

Q: Can L112BX be used as a direct replacement for L112B?

A: Yes. The L112BX is a direct functional equivalent. Both connectors share identical electrical specifications (48VDC, 250 mA), mechanical dimensions (6.35mm mating diameter), contact configuration (3-conductor TRS), mounting type (panel mount), and termination method (solder eyelet). The primary difference is packaging format and inventory availability.

Q: What does "bulk packaging" mean for the L112BX?

A: Bulk packaging indicates the L112BX is supplied without individual retail packaging, typically in larger quantities per container. This packaging format is standard for production environments and high-volume procurement.

Q: Are there any compatibility concerns when substituting L112B with L112BX?

A: No compatibility concerns exist. Both connectors are mechanically and electrically identical. They mate with the same 6.35mm stereo plugs and function identically in panel mount applications.

Q: What is the significance of ROHS3 compliance on the L112BX?

A: ROHS3 compliance indicates the L112BX meets Restriction of Hazardous Substances Directive requirements, restricting specific hazardous materials in electrical and electronic equipment. This certification is relevant for applications subject to EU environmental regulations or customer specifications requiring ROHS compliance.

Q: Can these connectors be used interchangeably in the same circuit design?

A: Yes. The L112B and L112BX are interchangeable from both electrical and mechanical perspectives. Circuit designs using either part number will function identically, provided the application operates within the specified -20°C to 65°C temperature range and does not exceed 48VDC or 250 mA ratings.
