AXT346124 Equivalent & Substitute Parts

Part Overview

The AXT346124 is a 46-position rectangular connector socket manufactured by Panasonic Electric Works, designed for surface mount applications with gold-plated contacts and solder retention features. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity. The connector features outer shroud contacts and is suitable for applications requiring reliable interconnection in compact form factors.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AXT346124 is determined by the following critical parameters:

• Position Count: 46 positions (fixed requirement)
• Connector Type: Socket configuration with outer shroud contacts
• Pitch Tolerance: 0.016" (0.40mm) nominal, with allowance for compatible pitch standards
• Mounting Technology: Surface mount (SMD) compatibility
• Contact Material: Gold plating for corrosion resistance and electrical performance
• Compliance: RoHS compliance and MSL rating
• Mechanical Interface: Mated stacking height and board height compatibility

The identified substitute BM23PF0.8-46DP-0.35V(895) from Hirose Electric Co Ltd maintains functional equivalence through matching position count, surface mount technology, gold contact finish, and compliance certifications. Pitch variation (0.014" vs 0.016") represents a design consideration requiring PCB layout verification but does not preclude functional substitution in applications where mechanical tolerance permits.

Parameter Comparison

Engineering Selection Recommendations

The BM23PF0.8-46DP-0.35V(895) is an active product from Hirose Electric Co Ltd and represents a viable substitute for the obsolete AXT346124. Both components maintain RoHS compliance and MSL Level 1 ratings, ensuring compatibility with standard manufacturing and storage protocols.

Key considerations for selection:

• Product Availability: The Hirose component is actively manufactured with 2613 units in stock, compared to the Panasonic component's obsolete status with limited remaining inventory.
• Mechanical Footprint: The Hirose substitute features reduced mated stacking height (0.8mm vs 1.5mm) and lower profile above board (0.63mm vs 1.45mm), enabling space-constrained applications.
• Pitch Differential: The 0.014" (0.35mm) pitch of the Hirose component differs from the 0.016" (0.40mm) pitch of the original. PCB layout redesign is required to accommodate this pitch change.
• Connector Type Variation: The Hirose component is configured as a header, whereas the original is a socket. Mating interface design must account for this polarity reversal.

Frequently Asked Questions (FAQ)

Q: Can the BM23PF0.8-46DP-0.35V(895) be used as a direct drop-in replacement for the AXT346124?

A: No. While both components share 46 positions, gold plating, surface mount technology, and compliance certifications, the pitch difference (0.35mm vs 0.40mm) and connector type variation (header vs socket) require PCB redesign and mating interface reconfiguration.

Q: What is the significance of the pitch difference between these connectors?

A: Pitch determines the spacing between contact positions. The 0.014" (0.35mm) pitch of the Hirose component requires PCB traces and pad layouts to be redesigned from the original 0.016" (0.40mm) specification. This is not a minor adjustment and affects the entire interconnect footprint.

Q: Are both components RoHS compliant?

A: Yes. Both the AXT346124 and BM23PF0.8-46DP-0.35V(895) are RoHS compliant and carry MSL Level 1 ratings, indicating compatibility with standard manufacturing environments and unlimited shelf life under controlled storage.

Q: What does the connector type difference (socket vs header) mean for my application?

A: Socket connectors receive pins from a mating header connector. Header connectors provide the pins. Substituting a socket with a header requires redesign of the mating connector interface. The two cannot be directly mated without additional adapter hardware.

Q: Why is the Hirose component smaller in profile?

A: The BM23PF0.8-46DP-0.35V(895) achieves reduced stacking height (0.8mm vs 1.5mm) and lower board profile (0.63mm vs 1.45mm) through optimized contact geometry and compression design. This enables integration into space-constrained assemblies.

Q: Is the Hirose component available in the same packaging as the original?

A: The Hirose component is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. Packaging compatibility with existing production equipment should be verified.
