AXF6B4012 Equivalent & Substitute Parts

Part Overview

The AXF6B4012 is a 40-position rectangular connector header manufactured by Panasonic Electric Works, designed for flexible printed circuit (FPC) board applications. This surface mount component features outer shroud contacts with gold plating and solder retention capabilities. The part is classified as "Not For New Designs," indicating it has been superseded in the manufacturer's product line. Identifying equivalent substitute parts is necessary for ongoing production support, legacy system maintenance, and design flexibility when the primary part becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AXF6B4012 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 40
• Pitch: 0.014" (0.35mm)
• Number of Rows: 2
• Connector Type: Header, Outer Shroud Contacts
• Mounting Type: Surface Mount
• Contact Finish: Gold
• Mated Stacking Heights: 0.6mm
• Height Above Board: 0.018" (0.46mm)
• Features: Solder Retention
• RoHS Compliance: Required
• MSL Rating: 1 (Unlimited)

Both substitute parts listed below meet all mandatory matching parameters and are therefore electrically and mechanically interchangeable with the AXF6B4012 in applications requiring these specifications.

Frequently Asked Questions (FAQ)

Q: Can AXF6D4012 and AXG240144 be used interchangeably with AXF6B4012?

A: Yes. Both substitute parts match all critical electrical and mechanical parameters: 40 positions, 0.35mm pitch, 2-row configuration, gold contact finish, and identical stacking heights. All three parts are RoHS compliant with MSL 1 rating.

Q: What is the difference between the substitute parts?

A: The primary differences are product status and series designation. AXF6D4012 belongs to the A35UH series, while AXG240144 belongs to the S35 series. Both are active products with current manufacturing support. Inventory levels differ, with AXG240144 offering higher stock availability.

Q: Why is the AXF6B4012 marked "Not For New Designs"?

A: This designation indicates the part has been superseded in the manufacturer's product line. For new designs, AXF6D4012 or AXG240144 are the recommended alternatives. Existing designs using AXF6B4012 can continue production using either substitute without circuit modification.

Q: Are packaging differences significant for assembly?

A: Both substitute parts are supplied in Tape & Reel packaging, standard for automated surface mount assembly. The AXF6B4012 packaging specification was not provided in the available data. Tape & Reel format is compatible with standard pick-and-place equipment.

Q: Do the substitute parts require PCB layout changes?

A: No. All three parts share identical mounting footprints, pitch spacing, and height specifications. PCB layouts designed for AXF6B4012 accommodate both AXF6D4012 and AXG240144 without modification.

Q: What compliance certifications apply to these parts?

A: All three parts are RoHS compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. ECCN classification is EAR99 for all parts, and HTSUS code 8536.69.4040 applies uniformly.
