AXE140527D Equivalent & Substitute Parts

Part Overview

The AXE140527D is a 40-position rectangular connector socket manufactured by Panasonic Electric Works, designed for surface mount applications with center strip contacts and gold plating. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. The part belongs to the A4US series and maintains full RoHS compliance with MSL 1 rating.

Substitute Part Grouping Explanation

Substitute parts for the AXE140527D are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Connector Type & Position Count: All substitutes maintain socket configuration with 40 positions
Pitch & Row Configuration: 0.016" (0.40mm) pitch with 2-row arrangement preserved across all alternatives
Mounting & Physical Dimensions: Surface mount technology with identical height above board (0.030"/0.75mm) and mated stacking height (0.8mm)
Contact Finish: Gold plating maintained for all substitutes
Compliance: RoHS compliance and MSL 1 rating consistent across all parts

The substitute parts differ primarily in series designation (A4US vs. A4S), packaging format, and product status, but maintain electrical and mechanical equivalence for direct substitution in applications designed for the AXE140527D.

Engineering Selection Recommendations

Primary Substitutes (A4US Series - Same Base Product)

AXE140124 and AXE140527 are direct parametric equivalents within the A4US series. Both parts maintain identical electrical and mechanical specifications to the AXE140527D while offering active product status. These parts are preferred for applications requiring continuity with the original design series. Both are available in Tape & Reel packaging for automated assembly processes.

Alternative Substitute (A4S Series)

AXE540127 provides functional equivalence across all critical parameters but operates within the A4S series designation. This part offers the highest inventory availability (114,630 units) and active product status. The mated stacking height specification includes both 0.8mm and 1mm options, providing additional flexibility for certain board layout configurations. This part is suitable for applications where series compatibility is not a design constraint.

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

Frequently Asked Questions (FAQ)

Q: Can AXE540127 be used as a direct replacement for AXE140527D?

A: Yes. AXE540127 maintains all critical electrical and mechanical parameters: 40-position socket configuration, 0.016" (0.40mm) pitch, 2-row arrangement, surface mount technology, gold contact finish, and identical height above board. The primary difference is series designation (A4S vs. A4US) and packaging format (Tape & Reel vs. bulk).

Q: What is the difference between AXE140124 and AXE140527?

A: Both parts are parametric equivalents within the A4US series with identical specifications. The difference lies in their base product number designation (AXE140 base) and internal part coding. Both are suitable for direct substitution of the AXE140527D.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel (TR) packaging and bulk packaging contain identical components. Packaging selection depends on assembly process requirements and handling procedures. Tape & Reel format is standard for automated pick-and-place assembly.

Q: Are all substitutes RoHS compliant?

A: Yes. AXE140124, AXE140527, and AXE540127 are all RoHS compliant with MSL 1 rating, matching the compliance profile of the AXE140527D.

Q: What does the mated stacking height specification mean?

A: Mated stacking height defines the vertical distance when the connector socket is mated with its corresponding plug. AXE140527D specifies 0.8mm. AXE540127 offers both 0.8mm and 1mm options, providing flexibility for applications with specific board-to-board spacing requirements.

Q: Why is AXE140527D classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. AXE140124 and AXE140527 (both active) provide continuity within the same A4US series, while AXE540127 (active, A4S series) offers an alternative from the same manufacturer with higher inventory availability.
