SS-641010-NF-50 Equivalent & Substitute Parts

Part Overview

The SS-641010-NF-50 is an active modular jack connector manufactured by Stewart Connector, designed for 10p10c (RJ50) applications with 90° right-angle orientation. This unshielded through-hole connector features solder termination and board lock functionality. The part is ROHS3 compliant and maintains an operating temperature range of -40°C to 85°C. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, supply chain considerations, or design flexibility within the allowed parameter tolerance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SS-641010-NF-50 is determined by strict equivalence across the following critical parameters:

• Connector type (Jack)
• Contact configuration (10p10c / RJ50)
• Mechanical orientation (90° right-angle)
• Mounting method (through-hole, solder termination)
• Electrical shielding classification (unshielded)
• Contact finish specification (gold plating at 50.0µin thickness)
• Operating temperature range (-40°C to 85°C minimum)
• Regulatory compliance (ROHS3)

The identified substitute part 5558065-1 meets all mandatory electrical and mechanical parameters. Variations in housing material (thermoplastic vs. polyamide), contact material composition (copper alloy vs. phosphor bronze), and mechanical features (board lock vs. board guide) do not affect functional interchangeability within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

Both the SS-641010-NF-50 and 5558065-1 are active products with current manufacturing status. Selection between these parts should be based on:

• Availability and lead time requirements
• Inventory levels (SS-641010-NF-50: 1149 pcs; 5558065-1: 2917 pcs)
• Compliance certifications (both ROHS3 compliant, both EAR99 classification)
• Housing material preference (thermoplastic vs. polyamide)
• Mechanical feature requirements (board lock vs. board guide)

Both parts satisfy identical electrical specifications, contact geometry, and environmental operating conditions. The substitute part carries Cat3 rating designation, which does not alter the core substitution eligibility based on the provided parameters.

Frequently Asked Questions (FAQ)

Q: Can 5558065-1 be used as a direct replacement for SS-641010-NF-50 in PCB assembly?

A: Yes. Both parts share identical contact configuration (10p10c), orientation (90° right-angle), mounting method (through-hole solder), and operating temperature range. The parts are mechanically and electrically interchangeable within the specified parameter set.

Q: What is the difference between board lock and board guide features?

A: Board lock and board guide are mechanical retention features on the connector housing. Both provide board-level stability during assembly and operation. The choice between them depends on application-specific mechanical requirements not specified in the core electrical parameters.

Q: Are there differences in contact material that affect performance?

A: The main part uses copper alloy contacts; the substitute uses phosphor bronze. Both materials are plated with gold at 50.0µin thickness. Contact material composition does not alter the electrical performance or interchangeability within the specified parameter tolerance.

Q: Does the Cat3 rating on 5558065-1 affect substitution eligibility?

A: No. The Cat3 rating is an additional specification on the substitute part. It does not conflict with the core electrical and mechanical parameters that determine substitution eligibility.

Q: What is the packaging format for both parts?

A: Both parts are supplied in tray packaging, suitable for automated assembly processes.
