Switchcraft 112A Barrel Connector - Equivalent & Substitute Parts

Part Overview

The Switchcraft 112A is a 6.35mm (0.250", 1/4") mono headphone jack connector designed for panel mount, through-hole applications. This connector features a single internal switch, solder eyelet termination, and is rated for 48VDC at 3A. The 112A is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

The Switchcraft 112AX qualifies as a direct substitute for the 112A based on identical electrical and mechanical parameters. Substitution is determined by the following critical parameters:

• Connector type and mating diameter (6.35mm mono jack)
• Contact configuration (2 conductors, 3 contacts with single internal switch)
• Mounting specifications (panel mount, through-hole with 3/8"-32 thread)
• Electrical ratings (48VDC, 3A)
• Termination method (solder eyelet)
• Physical dimensions (0.375" panel hole size)

The 112AX maintains full compatibility with the 112A across all specified electrical and mechanical interfaces.

Parameter Comparison

Engineering Selection Recommendations

The Switchcraft 112AX is the direct functional equivalent of the 112A. Both parts are identical in electrical performance, mechanical interface, and physical dimensions. The primary distinction is product lifecycle status: the 112A is obsolete while the 112AX is active production.

For new designs or component replacement, the 112AX is the appropriate selection. The 112AX provides the additional benefit of RoHS3 compliance, whereas the 112A is RoHS non-compliant. Both parts maintain REACH Unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can the 112AX be used as a direct replacement for the 112A?

A: Yes. The 112AX is electrically and mechanically identical to the 112A. All electrical ratings, contact configurations, mounting specifications, and physical dimensions are equivalent. The 112AX is the active production equivalent of the obsolete 112A.

Q: What is the difference between the 112A and 112AX?

A: The primary differences are product status and regulatory compliance. The 112A is obsolete; the 112AX is active production. The 112AX is RoHS3 compliant, while the 112A is RoHS non-compliant. All other specifications are identical.

Q: Are there packaging differences between these parts?

A: The 112A is supplied with standard packaging. The 112AX is supplied in bulk packaging. Both contain the same connector assembly with nut and washer.

Q: What are the critical parameters for substitution compatibility?

A: Substitution compatibility is determined by: 6.35mm mating diameter, mono signal configuration, 2 conductors with 3 contacts, single internal switch, panel mount through-hole mounting, 3/8"-32 thread, 0.375" panel hole size, 48VDC rating, and 3A current rating.

Q: Is the 112AX suitable for new product designs?

A: Yes. The 112AX is active production and RoHS3 compliant, making it appropriate for new designs requiring a 6.35mm mono panel-mount phone jack connector with solder eyelet termination.
