Switchcraft 112B Equivalent & Substitute Parts

Part Overview

The Switchcraft 112B is a 6.35mm (1/4") stereo phone jack connector designed for panel mount, through-hole applications. This barrel connector features three conductors (TRS configuration) with solder eyelet termination and is rated for 48VDC at 3A. The 112B is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications requiring this connector type.

Substitute Part Grouping Explanation

The Switchcraft 112BX qualifies as a direct substitute for the 112B based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Connector type and gender match (Phone Jack, Female)
• Mating diameter and signal configuration are identical (6.35mm, Stereo TRS)
• Mounting configuration and termination method are the same (Panel Mount, Through Hole, Solder Eyelet)
• Electrical ratings are equivalent or exceed requirements (48VDC, 3A)
• Physical dimensions match (Panel Hole Size: 0.375", Thread Size: 3/8"-32)
• Operating temperature range is maintained (-20°C ~ 65°C)

The 112BX maintains all functional and dimensional specifications of the 112B, enabling direct substitution in applications where the original part is no longer available.

Parameter Comparison

Engineering Selection Recommendations

The Switchcraft 112BX is the appropriate substitute for the obsolete 112B. Both parts are manufactured by Switchcraft Inc. and share identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status and regulatory compliance: the 112B is obsolete and RoHS non-compliant, while the 112BX is an active product with ROHS3 compliance. For new designs and ongoing production requiring this connector type, the 112BX should be selected. For legacy system maintenance where RoHS compliance is not a requirement, the 112BX remains functionally equivalent and maintains full compatibility with existing 112B installations.

Frequently Asked Questions (FAQ)

Q: Can the 112BX be used as a direct replacement for the 112B?

A: Yes. The 112BX is a direct substitute. All electrical ratings (48VDC, 3A), mechanical dimensions (6.35mm mating diameter, 0.375" panel hole, 3/8"-32 thread), signal configuration (Stereo TRS, 3 conductors), and termination method (Solder Eyelet) are identical between the two parts.

Q: What is the primary difference between the 112B and 112BX?

A: The 112B is obsolete and RoHS non-compliant, while the 112BX is an active product with ROHS3 compliance. Functionally and mechanically, they are equivalent.

Q: Are there packaging differences between these parts?

A: The 112B packaging specification is not provided. The 112BX is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Will the 112BX work in applications originally designed for the 112B?

A: Yes. The 112BX maintains identical operating temperature range (-20°C ~ 65°C), voltage rating (48VDC), current rating (3A), and all mechanical specifications. No design modifications are required.

Q: Should I consider RoHS compliance when selecting between these parts?

A: If your application or market requires RoHS compliance, the 112BX (ROHS3 compliant) is the appropriate choice. The 112B is RoHS non-compliant and should not be used in applications with RoHS requirements.
