Engineering Selection Recommendations

For applications currently using AXE120124D, the following active alternatives are available:

AXE120124 and AXE120527 are parametric equivalents within the A4US series, maintaining identical electrical and mechanical specifications. Both parts are in active production status with Tape & Reel packaging, providing supply continuity for new designs and production runs.

AXE520127 is a series variant (A4S) that maintains all critical functional parameters including position count, pitch, mounting type, contact finish, and stacking heights. The mated stacking height specification includes both 0.8mm and 1mm options, providing additional flexibility for certain board layout configurations. This part is in active production with the highest current inventory level.

All substitute parts maintain RoHS compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can AXE120124D be directly replaced with AXE520127?

A: Yes. Both parts maintain identical electrical and mechanical parameters: 20 positions, 0.016" (0.40mm) pitch, 2-row configuration, surface mount technology, gold contact finish, and 0.8mm mated stacking height. The series designation change (A4US to A4S) does not affect functional compatibility. The additional 1mm stacking height option in AXE520127 does not impact applications designed for 0.8mm operation.

Q: What is the difference between AXE120124D and AXE120124?

A: Both parts are identical in electrical and mechanical specifications. The primary difference is product status: AXE120124D is obsolete, while AXE120124 is in active production. AXE120124 is supplied in Tape & Reel packaging, suitable for automated assembly processes.

Q: Are all substitute parts RoHS compliant?

A: Yes. AXE120124D, AXE120124, AXE120527, and AXE520127 are all RoHS compliant with MSL 1 (unlimited) moisture sensitivity rating.

Q: Does packaging format affect connector performance?

A: No. Packaging format (Tape & Reel) affects handling and assembly logistics but does not alter electrical or mechanical performance. The connector specifications remain identical regardless of packaging.

Q: Which substitute part has the best current availability?

A: AXE520127 has the highest inventory level at 6917 pieces in stock, followed by AXE120527 at 965 pieces and AXE120124 at 659 pieces.
