Key Parameters

Substitute Part Grouping Explanation

The MN112A has one identified direct substitute: MN112AX. Substitution eligibility is determined by strict equivalence across the following critical parameters:

• Connector type (Phone Jack)
• Gender (Female)
• Signal configuration (Mono)
• Mating diameter (6.35mm / 0.250")
• Contact count (2 Conductors, 3 Contacts)
• Internal switch configuration (Single Switch)
• Mounting type (Panel Mount, Through Hole)
• Termination method (Solder Eyelet)
• Shielding (Unshielded)
• Contact material and plating (Brass with Tin plating)
• Housing material (Thermoplastic)
• Panel hole size (0.375" / 9.52mm)
• Thread size (3/8"-32)
• Regulatory compliance (ROHS3, REACH Unaffected)

The MN112AX meets all substitution criteria and is packaged in bulk format, distinguishing it from the standard packaging of the MN112A.

Parameter Comparison

Engineering Selection Recommendations

Both the MN112A and MN112AX are active products manufactured by Switchcraft Inc. and maintain full compliance with ROHS3 and REACH regulations. Selection between these parts should be based on packaging requirements and inventory availability. The MN112AX offers higher stock levels (1156 units) and bulk packaging, making it suitable for high-volume production runs. The MN112A maintains standard packaging with adequate inventory (661 units) for standard procurement cycles. Both parts are electrically and mechanically equivalent and interchangeable in all applications requiring a 6.35mm mono headphone jack connector with panel-mount, through-hole solder eyelet termination.

Frequently Asked Questions (FAQ)

Q: Are MN112A and MN112AX electrically identical? A: Yes. Both parts are identical in electrical performance, contact configuration, signal handling, and switching characteristics. They differ only in packaging format.

Q: Can MN112AX be used as a direct replacement for MN112A? A: Yes. The MN112AX is a direct substitute. All mechanical dimensions, mounting specifications, termination methods, and electrical parameters are equivalent.

Q: What is the difference between MN112A and MN112AX? A: The primary difference is packaging. MN112A uses standard packaging, while MN112AX is supplied in bulk packaging. Both are from the same Hi-D JAX® MN-11* series and manufactured by Switchcraft Inc.

Q: Are there any compliance differences between these parts? A: No. Both parts carry identical RoHS3 compliance and REACH Unaffected status.

Q: What panel hole size is required for installation? A: Both connectors require a 0.375" (9.52mm) panel hole with 3/8"-32 threading for the mounting nut.

Q: How many contacts does this connector have? A: The connector has 3 total contacts supporting 2 conductors in a mono configuration with a single internal switch.
