Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the A-2014-3-4-R is determined by the following critical parameters:

• Connector type (Jack)
• Contact configuration (4P4C / RJ9, RJ10, RJ22)
• Port and row count (1 port, 1 row)
• Mounting method (Through Hole)
• Termination type (Solder)
• Shielding classification (Unshielded)
• Contact material and finish specifications (Phosphor Bronze with Gold plating)
• Operating temperature compatibility (-40°C to 85°C)

The substitute part A-20140 meets all these criteria and is manufactured by the same supplier, ensuring mechanical and electrical compatibility with applications originally designed for the A-2014-3-4-R.

Parameter Comparison

Engineering Selection Recommendations

The A-20140 is the manufacturer-recommended substitute for the obsolete A-2014-3-4-R. Both components share identical electrical and mechanical specifications, including contact configuration, material composition, and operating parameters. The primary distinction is product status: A-20140 is currently in active production with confirmed inventory availability (1241 units), whereas A-2014-3-4-R is obsolete with limited remaining stock (782 units).

The A-20140 includes additional features (Solder Retention) and offers user-selectable orientation flexibility compared to the fixed vertical orientation of the main part. Both components maintain full REACH compliance and EAR99 export classification. For new designs and ongoing procurement, A-20140 is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can A-20140 directly replace A-2014-3-4-R in existing applications?

A: Yes. Both components are 4P4C jack connectors with identical contact configurations, materials, finishes, and operating temperature ranges. The electrical and mechanical interfaces are equivalent.

Q: What is the difference between the orientation specifications?

A: A-2014-3-4-R has fixed vertical orientation. A-20140 offers user-selectable orientation, providing greater design flexibility without affecting electrical performance or mechanical compatibility.

Q: Are there packaging differences between these parts?

A: A-2014-3-4-R packaging is not specified in available data. A-20140 is supplied in Tray packaging. Verify packaging requirements for your procurement process.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are REACH Unaffected and classified as EAR99 for export purposes. Both maintain MSL 1 (Unlimited) moisture sensitivity ratings.

Q: Why is A-2014-3-4-R listed as obsolete?

A: Product obsolescence is determined by the manufacturer. A-20140 is the active production equivalent and is the recommended selection for all new applications and ongoing procurement.
