AXT870124 Equivalent & Substitute Parts

Part Overview

The AXT870124 is a 70-position rectangular connector header manufactured by Panasonic Electric Works, designed for surface mount applications with gold-plated contacts and outer shroud configuration. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing production and maintenance applications. The connector features solder retention and operates with unlimited moisture sensitivity rating (MSL 1), suitable for standard industrial and commercial environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AXT870124 is determined by the following critical parameters:

• Connector Type: Header with outer shroud contacts (maintains mechanical and electrical interface compatibility)
• Number of Positions: 70 positions (ensures pin count compatibility with mating receptacles)
• Number of Rows: 2 rows (preserves physical layout and contact arrangement)
• Mounting Type: Surface mount (maintains PCB assembly process compatibility)
• Contact Finish: Gold (ensures electrical performance and corrosion resistance equivalent)
• Features: Solder retention (maintains assembly reliability)

The substitute part DF37B-70DP-0.4V(51) from Hirose Electric Co Ltd satisfies these core substitution criteria. While pitch specifications differ (0.014" vs 0.016"), both connectors maintain the 70-position, 2-row header configuration with gold contacts and surface mount capability, allowing functional equivalence in applications where the connector footprint can accommodate the dimensional variance.

Parameter Comparison

Engineering Selection Recommendations

The DF37B-70DP-0.4V(51) serves as the primary equivalent for the obsolete AXT870124. Selection of this substitute is supported by:

• Product Status Alignment: The Hirose part maintains active production status, ensuring long-term availability and supply chain continuity.
• Regulatory Compliance: RoHS compliance of the DF37B-70DP-0.4V(51) meets current environmental standards, whereas the AXT870124 status is not specified.
• Functional Equivalence: Both connectors maintain 70-position, 2-row header configuration with gold contacts and surface mount assembly compatibility.
• Dimensional Compatibility: Mated stacking heights (1mm vs 0.98mm) and height above board (0.033" vs 0.030") represent negligible variance for standard PCB applications.

The pitch difference (0.35mm vs 0.40mm) requires PCB footprint evaluation to confirm accommodation within existing design constraints.

Frequently Asked Questions (FAQ)

Q: Can the DF37B-70DP-0.4V(51) directly replace the AXT870124 without PCB modification?

A: Direct replacement depends on PCB footprint design. The pitch difference (0.35mm vs 0.40mm) may require footprint adjustment. Verify that the PCB layout accommodates the 0.40mm pitch spacing of the Hirose connector.

Q: Are the mating receptacles interchangeable between these two connectors?

A: Mating receptacles are manufacturer-specific. Confirm that existing receptacles are compatible with the Hirose DF37B series before substitution.

Q: What is the significance of the MSL 1 rating for both connectors?

A: MSL 1 (Unlimited) indicates unlimited shelf life without moisture bake-out requirements, suitable for standard storage and handling conditions in industrial environments.

Q: Why is the AXT870124 classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The DF37B-70DP-0.4V(51) provides functional continuity for applications requiring 70-position surface mount headers with gold contacts.

Q: Does the RoHS compliance of the DF37B-70DP-0.4V(51) affect compatibility?

A: RoHS compliance ensures the substitute meets current environmental regulations. This status does not affect electrical or mechanical compatibility with the original design.
