Substitute Part Grouping Explanation

Substitution compatibility for the 22-4511-10 is determined by the following critical parameters:

Position Count and Row Spacing: Both must match exactly at 22 positions with 0.4" (10.16mm) row spacing to ensure mechanical fit on PCB layouts
Pitch Specifications: Mating pitch of 0.100" (2.54mm) and post pitch of 0.100" (2.54mm) are mandatory for component alignment
Contact Finish: Tin plating on both mating and post contacts ensures solder compatibility
Mounting Configuration: Through-hole solder termination is required for direct PCB integration
Operating Temperature Range: -55°C ~ 105°C operational envelope must be maintained
Electrical Performance: Current rating of 1 A and contact resistance specifications must support circuit requirements
Compliance Standards: UL94 V-0 flammability rating and RoHS/REACH compliance status are critical for regulatory adherence

The TE Connectivity AMP Connectors 1571550-7 meets all mandatory mechanical and electrical parameters for direct substitution.

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 1571550-7 is a direct functional equivalent to the obsolete Aries Electronics 22-4511-10. Both components share identical mechanical specifications, electrical operating parameters, and compliance certifications. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The primary difference between the two components is the contact material composition: the original uses phosphor bronze while the substitute uses beryllium copper. Both materials are suitable for tin-plated contact applications and maintain equivalent electrical performance within the specified operating temperature range of -55°C ~ 105°C.

Both components meet UL94 V-0 flammability requirements and maintain Moisture Sensitivity Level 1 (Unlimited) classification. The substitute part carries RoHS compliance certification, supporting regulatory requirements for new designs and legacy system updates.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1571550-7 be used as a direct replacement for the Aries Electronics 22-4511-10?

A: Yes. Both components share identical position counts (22), row spacing (0.4"), pitch specifications (0.100"), contact finish (tin), mounting type (through-hole), and operating temperature range (-55°C ~ 105°C). Mechanical and electrical compatibility is confirmed.

Q: What is the difference in contact material between these two parts?

A: The original Aries part uses phosphor bronze contacts, while the TE Connectivity substitute uses beryllium copper contacts. Both materials are compatible with tin plating and provide equivalent electrical performance for this application class.

Q: Are there any compliance or certification differences?

A: Both components meet UL94 V-0 flammability standards and maintain MSL 1 (Unlimited) moisture sensitivity classification. The substitute part carries RoHS compliance certification, supporting current regulatory requirements.

Q: What is the availability status of each part?

A: The Aries Electronics 22-4511-10 is obsolete with limited remaining inventory. The TE Connectivity 1571550-7 is in active production, ensuring reliable long-term availability for new orders and system maintenance.

Q: Are the termination post lengths identical?

A: The original part specifies 0.150" (3.81mm) post length, while the substitute specifies 0.125" (3.18mm). This difference may affect PCB design considerations for through-hole solder depth and board thickness compatibility.
