Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AXG8340J4A is determined by strict alignment of the following critical parameters:

• Manufacturer & Series: Panasonic Electric Works A35US series maintains mechanical and electrical compatibility
• Connector Type: Plug configuration with outer shroud contacts
• Pitch & Row Configuration: 0.014" (0.35mm) pitch with 2-row layout
• Mounting Technology: Surface mount assembly requirement
• Contact Finish: Gold plating for electrical performance consistency
• Physical Envelope: Mated stacking height of 0.6mm and height above board of 0.018" (0.46mm)
• Compliance: RoHS compliance and MSL rating of 1

The AXG834044A qualifies as a substitute based on these parameters, with the primary distinction being position count variation within the same connector family.

Parameter Comparison

Engineering Selection Recommendations

Both the AXG8340J4A and AXG834044A are classified as obsolete products within the Panasonic Electric Works A35US rectangular connector series. Selection between these parts must account for position count requirements: the main part provides 36 positions (34 signal + 2 power), while the substitute provides 34 positions. Both components maintain identical mechanical envelope, pitch, mounting technology, and compliance certifications. The choice between these parts depends solely on the circuit design requirement for the number of interconnection positions. Both parts carry RoHS compliance and MSL rating 1, ensuring equivalent environmental and handling characteristics.

Frequently Asked Questions (FAQ)

Q: Can AXG834044A be used as a direct replacement for AXG8340J4A?

A: AXG834044A is mechanically and electrically compatible with AXG8340J4A within the A35US series. The primary difference is position count: AXG834044A provides 34 positions versus 36 positions in the main part. Substitution is valid only if the circuit design accommodates the reduced position count.

Q: Are there differences in physical dimensions between these parts?

A: No. Both parts share identical pitch (0.014"/0.35mm), mated stacking height (0.6mm), and height above board (0.018"/0.46mm). They are mechanically interchangeable in terms of PCB footprint and connector envelope.

Q: Do both parts have the same RoHS and MSL ratings?

A: Yes. Both AXG8340J4A and AXG834044A are RoHS compliant with MSL rating 1 (unlimited moisture sensitivity level), ensuring equivalent environmental compliance and handling requirements.

Q: What is the significance of the "34 + 2 Power" designation in the main part?

A: The AXG8340J4A designates 34 signal positions plus 2 dedicated power positions for a total of 36 positions. The AXG834044A provides 34 total positions without this power position separation. Design requirements determine which configuration is appropriate.

Q: Are both parts suitable for surface mount assembly?

A: Yes. Both components are surface mount connectors with identical mounting technology, solder retention features, and gold contact finish, making them compatible with standard SMD assembly processes.
