Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AXE518124 is determined by strict equivalence across the following critical parameters:

• Connector Type: Socket with center strip contacts (electrical interface requirement)
• Number of Positions: 18 positions (pin count and layout compatibility)
• Pitch: 0.016" (0.40mm) (mechanical spacing and mating compatibility)
• Number of Rows: 2 rows (physical arrangement and footprint)
• Mounting Type: Surface mount (assembly process compatibility)
• Contact Finish: Gold (electrical performance and corrosion resistance)
• Height Above Board: 0.030" (0.75mm) (clearance and PCB integration)
• Mated Stacking Heights: 0.8mm or 1mm (connector interface compatibility)
• RoHS Compliance: Required for regulatory alignment
• Moisture Sensitivity Level: MSL 1 (storage and handling requirements)

The AXE118527A meets all substitution criteria and is classified as an equivalent alternative.

Parameter Comparison

Engineering Selection Recommendations

The AXE118527A qualifies as a direct functional equivalent to the AXE518124 based on electrical and mechanical parameter alignment. Both components are RoHS compliant and carry MSL 1 classification, ensuring equivalent regulatory and environmental performance. The primary distinction lies in series designation (A4S versus A4US) and packaging format (Cut Tape versus Strip), neither of which affects electrical or mechanical compatibility in the application.

The mated stacking height specification for AXE118527A (0.8mm only) represents a subset of the AXE518124 range (0.8mm and 1mm). Applications requiring the 1mm stacking height must confirm compatibility with the substitute part's 0.8mm specification before implementation.

Both parts are classified as obsolete, indicating limited future availability. Inventory levels are adequate for current procurement (AXE518124: 2099 units; AXE118527A: 974 units).

Frequently Asked Questions (FAQ)

Q: Can AXE118527A be used as a direct replacement for AXE518124 in existing designs?

A: Yes. Both parts share identical electrical and mechanical specifications across all critical parameters: 18-position socket configuration, 0.016" (0.40mm) pitch, 2-row layout, surface mount assembly, gold contact finish, and 0.030" (0.75mm) height above board. RoHS compliance and MSL 1 ratings are equivalent.

Q: What is the difference between the A4S and A4US series designations?

A: Series designation reflects internal Panasonic Electric Works product line organization. Both A4S and A4US series connectors in this specification maintain identical electrical and mechanical performance for the 18-position socket configuration.

Q: Does packaging format (Cut Tape versus Strip) affect component functionality?

A: No. Packaging format affects only handling, storage, and assembly logistics. The electrical and mechanical properties of the connector remain unchanged. Cut Tape (CT) and Strip packaging contain identical components.

Q: Is the 0.8mm mated stacking height of AXE118527A compatible with designs specified for 0.8mm or 1mm?

A: The AXE118527A supports 0.8mm mating only. Designs requiring 1mm stacking height must confirm mechanical clearance and mating interface compatibility before substitution.

Q: Are both parts suitable for new production designs?

A: Both AXE518124 and AXE118527A are classified as obsolete. While current inventory is available, neither part is recommended for new production designs. Panasonic Electric Works should be consulted for current-generation alternatives within the rectangular connector portfolio.

Q: What compliance certifications apply to both parts?

A: Both parts are RoHS compliant and carry Moisture Sensitivity Level 1 (unlimited storage without desiccant requirements). ECCN classification is EAR99 for both components.
