Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Aries Electronics 22-4511-11 is determined by the following critical parameters:

• Position Count & Row Spacing: Must be 22 positions with 0.4" (10.16mm) row spacing to maintain mechanical compatibility with existing PCB layouts
• Pitch Specifications: Both mating pitch (0.100" / 2.54mm) and post pitch (0.100" / 2.54mm) must match exactly
• Contact Finish: Gold plating is required for corrosion resistance and electrical performance consistency
• Mounting & Termination: Through-hole solder termination is mandatory for PCB assembly compatibility
• Operating Temperature: Must support -55°C ~ 125°C range for equivalent thermal performance
• Electrical Ratings: Current rating of 1 A and UL94 V-0 flammability classification establish baseline performance and safety requirements

The TE Connectivity AMP Connectors 2-1571550-7 meets all critical substitution criteria across these parameters.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 2-1571550-7 is a qualified substitute for the obsolete Aries Electronics 22-4511-11 based on the following engineering criteria:

Mechanical Compatibility: Both parts share identical position counts (22), row spacing (0.4"), and pitch specifications (0.100" mating and post). PCB footprints are mechanically compatible.

Electrical Performance: Both sockets operate across the -55°C ~ 125°C temperature range with UL94 V-0 flammability ratings. The TE part features thicker gold plating (25.0µin vs. 10.0µin) and beryllium copper contacts, which provide enhanced contact durability and lower contact resistance (10mOhm specified).

Compliance & Availability: The TE Connectivity part is RoHS Compliant and currently in active production with 815 units in stock, ensuring long-term procurement availability. The Aries part is obsolete with limited remaining inventory (1129 units).

Minor Dimensional Variance: The TE part has a 0.025" shorter termination post length (0.125" vs. 0.150"). This difference is within typical PCB design tolerances for through-hole solder joints but should be verified against specific PCB pad depth specifications during design review.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 2-1571550-7 be used as a direct replacement for the Aries 22-4511-11 in existing designs?

A: Yes, for mechanical and electrical compatibility. Both sockets accommodate 22-pin DIP integrated circuits with identical pitch and row spacing. The primary consideration is the 0.025" difference in termination post length, which should be evaluated against PCB pad specifications to ensure adequate solder joint formation.

Q: What is the significance of the different contact materials (Phosphor Bronze vs. Beryllium Copper)?

A: Both materials are standard for IC socket applications. Beryllium copper (TE part) offers superior spring properties and lower contact resistance. Phosphor bronze (Aries part) provides reliable performance at lower cost. The choice depends on application requirements for contact force and electrical performance.

Q: Why does the TE part have thicker gold plating?

A: The TE Connectivity part specifies 25.0µin (0.63µm) mating contact plating compared to 10.0µin (0.25µm) on the Aries part. Thicker plating extends contact life and improves corrosion resistance, particularly in environments with thermal cycling or humidity exposure.

Q: Are both parts RoHS compliant?

A: Yes. The Aries part is ROHS3 Compliant, and the TE part is RoHS Compliant. Both meet current environmental regulations for electronic component manufacturing.

Q: What is the contact resistance specification for the Aries part?

A: Contact resistance is not specified in the Aries part data. The TE Connectivity part specifies 10mOhm maximum contact resistance, which is typical for gold-plated IC sockets in this category.

Q: How do the moisture sensitivity levels compare?

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity concerns. These components can be stored and handled under standard conditions without special desiccant packaging requirements.
