Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AXG8500J4 is determined by the following critical parameters:

Electrical Compatibility:

• Pitch: 0.014" (0.35mm)
• Number of Rows: 2
• Contact Finish: Gold
• Mated Stacking Height: 0.6mm

Mechanical Compatibility:

• Mounting Type: Surface Mount
• Height Above Board: 0.018" (0.46mm)
• Solder Retention feature

Regulatory & Environmental:

• RoHS Compliance
• Moisture Sensitivity Level 1

The substitute part AXF6D5012 maintains compatibility across all critical electrical and mechanical parameters. The primary distinction is the connector type (Header vs. Plug) and position count (50 vs. 52), which reflects the active product line evolution within the A35 series family.

Parameter Comparison

Engineering Selection Recommendations

The AXG8500J4 is obsolete and no longer supported by the manufacturer. The AXF6D5012 is the active equivalent within the Panasonic A35 connector family, maintaining all critical electrical and mechanical specifications including pitch, stacking height, mounting configuration, and contact finish.

Both parts are RoHS compliant and carry MSL 1 rating, ensuring compatibility with standard surface mount assembly processes. The AXF6D5012 is currently in active production with documented inventory availability, making it the appropriate selection for new designs and production continuity.

The primary design consideration is the connector type transition from Plug to Header and the position count reduction from 52 to 50. These differences require circuit board layout verification to confirm mating interface compatibility with existing receptacle designs.

Frequently Asked Questions (FAQ)

Q: Can AXF6D5012 directly replace AXG8500J4 in existing assemblies?

A: Direct mechanical and electrical substitution is possible only if the mating receptacle is compatible with a Header connector type and can accommodate the 50-position configuration. The pitch, stacking height, and contact finish are identical, but the connector gender and position count must be verified against your specific application requirements.

Q: What is the significance of the position count difference (52 vs. 50)?

A: The AXG8500J4 includes 50 signal positions plus 2 dedicated power positions. The AXF6D5012 provides 50 total positions. Circuit board layout and signal routing must be evaluated to determine if this configuration change is compatible with your design.

Q: Are both parts suitable for the same assembly process?

A: Yes. Both parts are surface mount components with identical height above board specifications (0.018" / 0.46mm) and solder retention features. Both carry MSL 1 rating, requiring no special moisture control during storage or assembly.

Q: What packaging format is available for AXF6D5012?

A: AXF6D5012 is supplied in Tape & Reel (TR) format, standard for high-volume surface mount production. The AXG8500J4 packaging format is not specified in available documentation.

Q: Are there any compliance differences between these parts?

A: Both parts are RoHS compliant and carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications. No compliance barriers exist for substitution from a regulatory standpoint.
