Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AXK854145WG is determined by strict equivalence across the following critical parameters:

• Connector Type: Must be Header with Outer Shroud Contacts
• Position Count: Exactly 54 positions required
• Pitch Specification: 0.40mm (0.016") pitch mandatory
• Row Configuration: 2-row arrangement required
• Mounting Technology: Surface mount only
• Regulatory Compliance: RoHS compliant status
• Moisture Sensitivity: MSL 1 classification

The BM14HC-54DP-0.4V(51) from Hirose Electric Co Ltd meets all substitution criteria, maintaining identical electrical and mechanical specifications across all critical parameters.

Parameter Comparison

Engineering Selection Recommendations

The BM14HC-54DP-0.4V(51) serves as a direct functional equivalent to the obsolete AXK854145WG. Both components share identical specifications for position count, pitch, row configuration, and mounting technology. The Hirose part maintains active product status, ensuring continued availability and supply chain reliability. Both components satisfy RoHS compliance requirements and carry MSL 1 classification, indicating no moisture sensitivity constraints during storage and handling.

Selection of the BM14HC-54DP-0.4V(51) as a substitute is supported by regulatory alignment and active manufacturing status, eliminating obsolescence risk associated with the original Panasonic component.

Frequently Asked Questions (FAQ)

Q: Can the BM14HC-54DP-0.4V(51) be used as a direct replacement for the AXK854145WG?

A: Yes. Both components maintain identical specifications for connector type, position count (54), pitch (0.40mm), row configuration (2), and surface mount technology. Electrical and mechanical compatibility is assured.

Q: What is the significance of the pitch specification in connector substitution?

A: Pitch defines the center-to-center spacing between adjacent contacts. The 0.40mm pitch is a critical parameter that must match exactly to ensure proper mating with corresponding receptacle connectors. Pitch deviation prevents correct assembly.

Q: Does the contact finish difference affect substitution eligibility?

A: The AXK854145WG specifies gold contact finish, while the BM14HC-54DP-0.4V(51) does not specify contact finish in the provided data. Both components maintain RoHS compliance and MSL 1 classification, supporting functional equivalence for the specified application parameters.

Q: Why is the AXK854145WG classified as obsolete?

A: Obsolescence indicates the manufacturer has discontinued production. The BM14HC-54DP-0.4V(51) maintains active status, providing continued supply availability and design support.

Q: Are there any packaging or inventory considerations for this substitution?

A: The AXK854145WG has 717 pieces in stock, while the BM14HC-54DP-0.4V(51) has 895 pieces available. Both are new original components suitable for immediate procurement.
