Key Parameters

Substitute Part Grouping Explanation

The MS112BX is identified as a direct substitute for the MS112B based on the following alignment criteria:

Electrical Compatibility:

• Both parts maintain stereo (3 conductor, TRS) signal configuration
• Identical contact count: 3 conductors, 3 contacts
• Matching termination method: solder eyelet(s)
• Equivalent tin plating on contacts

Mechanical Compatibility:

• Both are female phone jack connectors
• Panel mount, through-hole mounting configuration
• Brass body construction with identical material specification
• Same series designation: Hi-D JAX® MS-11*

Functional Equivalence:

• Both are unshielded connectors
• Identical connector type classification
• Matching mounting hardware inclusion (nut and washer)

Compliance & Status:

• Both parts maintain ROHS3 compliance
• Active product status for both variants
• Equivalent regulatory certifications (REACH Unaffected, EAR99 classification)

The primary distinction between MS112B and MS112BX is the mating diameter specification: MS112B operates at 6.35mm (0.250"), while MS112BX operates at 5.23mm (0.206"). This diameter difference defines the mechanical interface and determines plug compatibility. Selection between these parts depends on the specific mating plug diameter required for the application.

Parameter Comparison

Engineering Selection Recommendations

MS112B Selection Criteria:

• Applications requiring 6.35mm (0.250", 1/4") mating diameter
• Standard headphone jack audio interface applications
• ROHS3 compliance requirement satisfied
• 856 units currently available for immediate procurement

MS112BX Selection Criteria:

• Applications requiring 5.23mm (0.206") mating diameter
• Compact audio connector applications with smaller plug specifications
• ROHS3 and REACH compliance requirements satisfied
• Higher inventory availability: 1114 units in stock
• Bulk packaging option available

Both parts maintain active product status and equivalent regulatory compliance. Selection is determined by the specific mating diameter requirement of the application's mating plug connector. Verify mating plug diameter specifications before component selection to ensure mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can MS112BX be used as a direct replacement for MS112B?

A: MS112BX is electrically and functionally equivalent to MS112B in terms of signal configuration (stereo TRS), contact count, termination method, and material specifications. However, the mating diameter differs: MS112B accepts 6.35mm plugs, while MS112BX accepts 5.23mm plugs. Substitution is only valid if the application's mating plug diameter matches the jack specification.

Q: What is the primary difference between these two parts?

A: The critical difference is the mating diameter. MS112B operates at 6.35mm (0.250"), the standard 1/4" headphone jack size. MS112BX operates at 5.23mm (0.206"), a smaller diameter specification. All other electrical and mechanical parameters remain equivalent.

Q: Are both parts ROHS3 compliant?

A: Yes, both MS112B and MS112BX are ROHS3 compliant. MS112BX additionally carries REACH Unaffected status.

Q: What termination method do these connectors use?

A: Both parts use solder eyelet termination, suitable for direct PCB soldering applications.

Q: How many contacts do these connectors have?

A: Both connectors feature 3 conductors and 3 contacts, configured for stereo (TRS) audio signal transmission.

Q: What is the mounting configuration?

A: Both parts are panel-mount, through-hole connectors designed for installation through a panel with solder connections on the reverse side.

Q: Are these connectors shielded?

A: No, both MS112B and MS112BX are unshielded connectors.

Q: What materials are used in the connector body?

A: Both connectors feature brass body construction with tin-plated contacts. MS112BX includes polyester glass-filled housing material.

Q: What is included with the MS112BX connector?

A: MS112BX includes 3 pieces per connector: the connector body, mounting nut, and washer.

Q: Which part has better inventory availability?

A: MS112BX has higher current inventory with 1114 units in stock compared to MS112B with 856 units.
