SS65400-003F Modular Connector Jack 4P4C Equivalent & Substitute Parts

Part Overview

The Stewart Connector SS65400-003F is a modular connector jack with 4 positions and 4 contacts (4P4C), commonly referenced as RJ9, RJ10, or RJ22 connector types. This component features vertical orientation, through-hole mounting, and solder termination with board lock functionality. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for new designs and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SS65400-003F is based on strict electrical and mechanical parameter matching. All substitute parts must maintain the following critical parameters:

• Connector type: Jack
• Contact configuration: 4P4C (RJ9, RJ10, RJ22)
• Mounting method: Through hole
• Orientation: Vertical
• Termination method: Solder
• Shielding: Unshielded
• Features: Board lock
• Operating temperature range: -40°C to 85°C
• Moisture sensitivity level: 1 (Unlimited)

The four Assmann WSW Components parts listed (A-2014-3-1-N-T, A-2014-3-2-N-T, A-2014-3-3-N-T, and A-2014-3-4-N-T-R) meet all these core requirements. These parts differ only in contact finish thickness specifications, which represent manufacturing variations within acceptable electrical performance parameters for this connector category.

Parameter Comparison

Engineering Selection Recommendations

All four Assmann WSW Components substitute parts are active products with ROHS3 compliance, providing regulatory advantage over the obsolete Stewart Connector SS65400-003F. Selection among the substitute options should be based on contact finish thickness requirements specific to your application:

• A-2014-3-1-N-T: Minimum contact finish thickness at 15.0µin (0.38µm)
• A-2014-3-2-N-T: Contact finish thickness matching the original part at 30.0µin (0.76µm)
• A-2014-3-3-N-T: Maximum contact finish thickness at 50.0µin (1.27µm)
• A-2014-3-4-N-T-R: Minimal contact finish thickness at 6.00µin (0.152µm)

All substitute parts maintain identical electrical and mechanical interface specifications, operating temperature range, and environmental compliance certifications. The housing material change from thermoplastic to polyester glass-filled material provides enhanced mechanical durability in the substitute parts.

Frequently Asked Questions (FAQ)

Q: Are all four Assmann WSW Components parts direct substitutes for the SS65400-003F?

A: Yes. All four parts (A-2014-3-1-N-T, A-2014-3-2-N-T, A-2014-3-3-N-T, and A-2014-3-4-N-T-R) maintain identical connector type, contact configuration, mounting method, orientation, termination, shielding, board lock feature, and operating temperature specifications. They differ only in contact finish thickness.

Q: What is the significance of contact finish thickness variation among the substitute parts?

A: Contact finish thickness affects contact durability and mating cycle life. The thickness options provided (6.00µin to 50.0µin) represent different performance grades within the same connector family. Selection depends on your application's mating cycle requirements and contact wear specifications.

Q: Can I use any of these substitute parts interchangeably on the same PCB?

A: Yes. All substitute parts share identical through-hole mounting footprints, vertical orientation, and solder termination specifications. They are mechanically and electrically interchangeable at the board level.

Q: What compliance advantages do the substitute parts offer?

A: The Assmann WSW Components substitutes are ROHS3 compliant, whereas the original Stewart Connector part does not specify RoHS status. All parts maintain REACH Unaffected status and EAR99 export classification.

Q: How does the housing material change affect performance?

A: The substitute parts use polyester glass-filled material instead of thermoplastic. This provides improved mechanical strength and thermal stability while maintaining the same operating temperature range (-40°C to 85°C) and moisture sensitivity level (MSL 1).

Q: Are there any packaging differences between the substitute parts?

A: All substitute parts are supplied in tray packaging. The original part packaging information was not specified in the available data.
