AXG7340J7A Equivalent & Substitute Parts

Part Overview

The AXG7340J7A is a 42-position rectangular connector socket manufactured by Panasonic Electric Works, featuring center strip contacts with surface mount gold plating. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing production support and design continuity. The connector accommodates 40 signal positions plus 2 dedicated power positions with a 0.35mm pitch configuration suitable for high-density applications.

Substitute Part Grouping Explanation

Substitution eligibility for the AXG7340J7A is determined by strict alignment of the following critical parameters:

Connector type and contact configuration (Socket, Center Strip Contacts)
Position count (42 positions: 40 signal + 2 power)
Pitch specification (0.35mm)
Row configuration (2 rows)
Mounting technology (Surface Mount)
Contact material and finish (Gold)
Environmental compliance (RoHS status)
Moisture sensitivity level (MSL 1)

Two substitute parts meet these criteria: the AXG7400J7A from Panasonic Electric Works (parametric equivalent) and the BM24-40DS/2-0.35V(53) from Hirose Electric Co Ltd (similar equivalent). Both maintain identical electrical and mechanical specifications within the allowed tolerance parameters for this connector category.

Engineering Selection Recommendations

The AXG7400J7A serves as a direct parametric equivalent within the Panasonic Electric Works product line. Both the main part and this substitute share identical electrical and mechanical specifications, including mated stacking height and height above board dimensions. However, both parts carry obsolete product status, limiting long-term availability.

The BM24-40DS/2-0.35V(53) from Hirose Electric Co Ltd is classified as active, providing superior long-term supply chain continuity. This substitute maintains all critical electrical parameters and connector geometry. The mated stacking height and height above board are slightly elevated (0.8mm and 0.80mm respectively versus 0.59mm and 0.60mm), which must be evaluated against specific PCB layout constraints. Both substitutes meet or exceed RoHS compliance requirements and maintain MSL 1 rating. The Hirose part offers significantly higher inventory availability (12694 units) compared to Panasonic alternatives.

Frequently Asked Questions (FAQ)

Q: Can the AXG7400J7A be used as a direct replacement for the AXG7340J7A?

A: Yes. The AXG7400J7A is a parametric equivalent with identical connector type, position count, pitch, row configuration, mounting type, contact finish, and environmental ratings. Both are Panasonic Electric Works products within the A35US series.

Q: What are the key differences between the Panasonic and Hirose substitutes?

A: The primary differences are product status and physical height. The Hirose BM24-40DS/2-0.35V(53) is active (versus obsolete for Panasonic parts), offers higher inventory availability, and features slightly increased mated stacking height (0.8mm versus 0.6mm) and height above board (0.80mm versus 0.59mm). All electrical and pitch specifications remain identical.

Q: Does the increased height of the Hirose connector affect compatibility?

A: The height difference must be evaluated against your specific PCB layout and mating component clearances. The 0.2mm increase in mated stacking height and 0.21mm increase in height above board may impact designs with tight vertical constraints. Mechanical verification against your assembly requirements is necessary.

Q: Are there packaging differences between these substitutes?

A: Yes. The Panasonic parts (AXG7340J7A and AXG7400J7A) are supplied in Strip packaging, while the Hirose BM24-40DS/2-0.35V(53) is supplied in Tape & Reel (TR) format. This affects handling, storage, and automated assembly processes.

Q: Which substitute offers the best long-term availability?

A: The Hirose BM24-40DS/2-0.35V(53) is the recommended choice for long-term production support due to its active product status and substantially higher inventory availability (12694 units). Both Panasonic alternatives are obsolete, limiting future procurement options.

Q: Do all three parts meet current environmental compliance standards?

A: Yes. The AXG7340J7A and AXG7400J7A are RoHS Compliant. The Hirose BM24-40DS/2-0.35V(53) meets the more stringent ROHS3 Compliant standard. All three maintain MSL 1 (Unlimited) moisture sensitivity rating.
