AXE124124D Equivalent & Substitute Parts

Part Overview

The AXE124124D is a 24-position rectangular connector socket manufactured by Panasonic Electric Works, designed for surface mount applications with center strip contacts and gold plating. This part operates in the A4US series and features solder retention for reliable PCB assembly. The AXE124124D is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. Substitute parts maintain identical electrical and mechanical specifications while offering active product status and improved availability.

Substitute Part Grouping Explanation

Substitution for the AXE124124D is determined by strict equivalence across the following critical parameters: connector type (socket with center strip contacts), position count (24), pitch (0.016"/0.40mm), row configuration (2 rows), mounting method (surface mount), contact finish (gold), and mechanical dimensions (0.8mm mated stacking height, 0.030" height above board). All substitute parts maintain identical RoHS compliance and MSL ratings.

The substitute parts are grouped into two categories:

Parametric Equivalents (Same Series A4US): AXE124124 and AXE124527 are direct parametric equivalents within the A4US series, differing only in packaging format (Tape & Reel) and product status (Active vs. Obsolete).

Similar Substitute (Series A4S): AXE524127 operates within the A4S series and maintains all critical electrical and mechanical parameters, with packaging in Tape & Reel format and active product status. Mated stacking height options include both 0.8mm and 1mm configurations.

Engineering Selection Recommendations

For applications currently using AXE124124D, transition to active product alternatives is recommended due to obsolete status. AXE124124 and AXE124527 are direct parametric equivalents within the A4US series and provide the most direct substitution path with identical mechanical and electrical specifications. Both parts carry active product status and RoHS compliance certification.

AXE524127 operates within the A4S series and maintains all critical functional parameters while offering the additional flexibility of dual mated stacking height options (0.8mm and 1mm). This part is suitable for applications where series variation is acceptable and the 1mm stacking height option provides design advantage.

All substitute parts maintain identical pitch, position count, contact finish, and compliance certifications as the original AXE124124D, ensuring functional compatibility in surface mount applications requiring 24-position rectangular connectors with gold-plated center strip contacts.

Frequently Asked Questions (FAQ)

Q: Can AXE124124 and AXE124527 be used interchangeably with AXE124124D?

A: Yes. AXE124124 and AXE124527 are parametric equivalents with identical electrical and mechanical specifications. The primary differences are packaging format (Tape & Reel vs. bulk) and product status (Active vs. Obsolete). Both maintain the same 24-position configuration, 0.016" pitch, gold contact finish, and surface mount design.

Q: What is the difference between AXE524127 and the A4US series parts?

A: AXE524127 operates within the A4S series rather than A4US. All critical parameters remain identical: 24 positions, 0.016" pitch, 2 rows, surface mount, gold finish, and solder retention. The A4S series offers dual mated stacking height options (0.8mm and 1mm) compared to the fixed 0.8mm specification of A4US parts.

Q: Are all substitute parts RoHS compliant?

A: Yes. AXE124124, AXE124527, and AXE524127 are all RoHS compliant with MSL rating of 1 (Unlimited), matching the compliance profile of AXE124124D.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel packaging (used for AXE124124, AXE124527, and AXE524127) and bulk packaging (AXE124124D) do not affect electrical or mechanical performance. Packaging selection is driven by assembly process requirements and inventory management.

Q: Can AXE524127 be used in designs requiring the 0.8mm stacking height?

A: Yes. AXE524127 supports both 0.8mm and 1mm mated stacking heights. Designs specifying 0.8mm stacking height are compatible with AXE524127 when the 0.8mm configuration is selected.
