Substitute Part Grouping Explanation

Substitution eligibility for the AXE550124 is determined by strict alignment of the following critical parameters:

  • Connector type: Socket, center strip contacts
  • Number of positions: 50
  • Pitch: 0.016" (0.40mm)
  • Number of rows: 2
  • Mounting type: Surface mount
  • Contact finish: Gold
  • Mated stacking heights: 0.8mm, 1mm
  • Height above board: 0.030" (0.75mm)
  • Solder retention feature

Substitute parts are grouped into two categories:

Direct Substitutes: Parts that match all critical parameters and belong to the same series (A4S). These provide full functional and mechanical compatibility.

Similar Substitutes: Parts that match all critical parameters but belong to a different series (A4US). These provide functional compatibility with potential minor mechanical or performance variations due to series differences.

Engineering Selection Recommendations

Primary Recommendation: AXE550127 or AXE550127A

Both AXE550127 and AXE550127A are active products within the A4S series and provide direct substitution for the obsolete AXE550124. These parts maintain identical electrical and mechanical specifications, including connector type, position count, pitch, mounting configuration, and contact finish. The distinction between these two direct substitutes is packaging: AXE550127 is supplied in Tape & Reel format, while AXE550127A is supplied in Strip format. Selection between these should be based on assembly process requirements and inventory management practices.

AXE550127A carries ROHS3 compliance certification, providing enhanced regulatory alignment for new designs or systems with updated compliance requirements.

Secondary Recommendation: AXE150527A

The AXE150527A is classified as a similar substitute due to its A4US series designation, which differs from the A4S series of the main part. While this part matches all critical electrical and mechanical parameters, the series difference indicates potential variations in design, performance characteristics, or manufacturing specifications not detailed in the provided parameters. This part is also obsolete. Selection of AXE150527A should be limited to applications where A4S series availability is constrained and where series compatibility has been independently verified.

Frequently Asked Questions (FAQ)

Q: Can AXE550127 and AXE550127A be used interchangeably with AXE550124?

A: Yes. Both parts are direct substitutes for AXE550124, matching all critical parameters: 50 positions, 0.016" pitch, 2 rows, surface mount configuration, gold contact finish, and solder retention. The difference between AXE550127 and AXE550127A is packaging format only. Both are active products, making them suitable for new production and replacement applications.

Q: What is the difference between AXE550127 and AXE550127A?

A: Both parts are electrically and mechanically identical. AXE550127 is packaged in Tape & Reel (TR) format, suitable for automated assembly processes. AXE550127A is packaged in Strip format, suitable for manual assembly or lower-volume applications. AXE550127A also carries ROHS3 compliance certification compared to standard RoHS compliance for AXE550127.

Q: Can AXE150527A replace AXE550124?

A: AXE150527A matches all critical electrical and mechanical parameters and is therefore functionally compatible. However, it belongs to the A4US series rather than the A4S series. Series differences may indicate design or performance variations not specified in the provided parameters. Additionally, AXE150527A is obsolete. This part should be considered only when A4S series alternatives are unavailable and series compatibility has been independently confirmed.

Q: Why is the mated stacking height specification different for AXE150527A?

A: AXE150527A specifies a single mated stacking height of 0.8mm, whereas AXE550124, AXE550127, and AXE550127A specify 0.8mm and 1mm. This difference reflects the A4US series design and may impact connector stack configurations in applications requiring the 1mm stacking height option.

Q: Are all substitute parts RoHS compliant?

A: Yes. AXE550124, AXE550127, AXE550127A, and AXE150527A are all RoHS compliant. AXE550127A carries the enhanced ROHS3 certification. All parts meet environmental and regulatory requirements for lead-free manufacturing and hazardous substance restrictions.

Q: What is the MSL rating for these connectors?

A: All parts carry MSL 1 (Unlimited), indicating no moisture sensitivity limitations. These connectors can be stored and handled without special moisture control measures and do not require baking prior to assembly.
