AXE520124 Equivalent & Substitute Parts

Part Overview

The AXE520124 is a 20-position rectangular connector socket with center strip contacts, surface mount configuration, and gold plating. Manufactured by Panasonic Electric Works as part of the A4S series, this component is classified as obsolete. Due to its obsolete status, equivalent and substitute parts from the active product lineup are necessary for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the AXE520124 is determined by the following critical parameters: connector type (socket, center strip contacts), number of positions (20), pitch (0.016"/0.40mm), number of rows (2), mounting type (surface mount), contact finish (gold), and moisture sensitivity level (MSL 1). Parts meeting all these criteria are classified as direct or similar substitutes based on product status and packaging configuration.

Direct Substitutes maintain identical electrical and mechanical specifications with active product status:

AXE520127 (Tape & Reel packaging, active status)
AXE520127A (Strip packaging, active status, ROHS3 compliant)

Similar Substitutes share core functional parameters but differ in series designation or stacking height specifications:

AXE120527A (A4US series, obsolete status, 0.8mm stacking height only)
AXE5E2026 (A4S series, active status, flash gold finish, 0.8mm stacking height only)

Engineering Selection Recommendations

For new designs and procurement, AXE520127 and AXE520127A are the primary recommended substitutes for the obsolete AXE520124. Both parts are active products with identical electrical and mechanical specifications. AXE520127A offers enhanced compliance with ROHS3 certification and REACH unaffected status, making it suitable for applications with stringent regulatory requirements. AXE520127 in Tape & Reel packaging is optimized for high-volume automated assembly operations.

AXE5E2026 serves as an alternative active substitute within the A4S series, with the distinction of flash gold contact finish and single stacking height specification (0.8mm). This part is suitable for applications where the 0.8mm stacking height is acceptable and flash gold plating meets electrical requirements.

AXE120527A, while functionally compatible, carries obsolete product status and should be considered only when existing inventory must be utilized. The A4US series designation and limited stacking height option (0.8mm only) represent design differences from the original AXE520124.

Frequently Asked Questions (FAQ)

Q: Can AXE520127 directly replace AXE520124 in existing designs? A: Yes. AXE520127 maintains identical electrical and mechanical specifications including connector type, position count, pitch, mounting configuration, and contact finish. The primary difference is active product status and Tape & Reel packaging.

Q: What is the difference between AXE520127 and AXE520127A? A: Both parts share identical core specifications. AXE520127A differs in packaging (Strip vs. Tape & Reel) and compliance certifications (ROHS3 Compliant and REACH Unaffected status vs. standard RoHS Compliant). Selection depends on assembly process requirements and regulatory compliance needs.

Q: Why does AXE5E2026 list only 0.8mm stacking height when AXE520124 supports both 0.8mm and 1mm? A: AXE5E2026 is specified with a single mated stacking height of 0.8mm. Applications requiring 1mm stacking height compatibility should use AXE520127 or AXE520127A instead.

Q: Is AXE120527A suitable as a substitute? A: AXE120527A meets all core functional requirements but carries obsolete product status and belongs to the A4US series rather than A4S. It should be considered only when existing inventory is available and the 0.8mm stacking height limitation is acceptable.

Q: What packaging options are available for substitutes? A: AXE520127 is supplied in Tape & Reel (TR) packaging for automated assembly. AXE520127A is supplied in Strip packaging. AXE5E2026 is supplied in Box packaging. Packaging selection should align with manufacturing process requirements and volume specifications.

Q: Are all substitute parts RoHS compliant? A: Yes. All substitute parts carry RoHS compliance certification. AXE520127A additionally meets ROHS3 Compliant and REACH Unaffected requirements for enhanced regulatory alignment.
