Substitute Part Grouping Explanation

Substitution eligibility for the M80-4000000FD-06-322-00-000 is determined by strict equivalence across the following critical parameters:

Connector type (Receptacle)
Contact type (Female Socket, Power)
Number of positions (6)
Pitch specification (0.157" / 4.00mm)
Mounting method (Through Hole)
Termination type (Solder)
Fastening mechanism (Screw Lock)
Current and voltage ratings (20A / 800V)
Operating temperature range (-55°C ~ 125°C)
Compliance certifications (UL94 V-0, ROHS3)

The M80-4000000FD-06-321-00-000 qualifies as a direct substitute based on these parameters. Both parts share the same base product number (M80-4000000FD), series designation (Datamate Mix-Tek), and all critical electrical and mechanical specifications. The primary distinction is product status: the substitute is active, whereas the original part is obsolete.

Engineering Selection Recommendations

The M80-4000000FD-06-321-00-000 is the appropriate substitute for the obsolete M80-4000000FD-06-322-00-000. Both parts maintain identical electrical performance specifications (20A, 800V), mechanical compatibility (6-position, 4.00mm pitch, through-hole solder termination), and regulatory compliance (UL94 V-0, ROHS3, REACH Unaffected).

The substitute part carries active product status, ensuring ongoing availability and supply chain support. The contact post length differs (0.138" versus 0.197"), which reflects a design refinement within the same connector family. This dimensional variation does not affect mating compatibility or electrical performance when used with corresponding plug connectors from the Datamate Mix-Tek series.

Selection of the active substitute eliminates obsolescence risk and aligns with current manufacturing standards while preserving full functional equivalence for board-to-board and cable interconnect applications.

Frequently Asked Questions (FAQ)

Q: Are these connectors mechanically compatible? A: Yes. Both parts share identical pitch (0.157" / 4.00mm), mounting type (through-hole), fastening mechanism (screw lock), and mated stacking height (7.3mm). The contact post length difference does not affect mating compatibility with standard Datamate Mix-Tek plug connectors.

Q: Can the substitute part be used in existing PCB designs? A: Yes. The substitute maintains the same through-hole footprint, solder termination, and electrical ratings. PCB layouts designed for the original part require no modification.

Q: What is the significance of the contact post length difference? A: The contact post length (0.197" versus 0.138") represents a design refinement within the Datamate Mix-Tek family. Both lengths provide adequate contact engagement and do not affect electrical performance or mating reliability.

Q: Are compliance certifications identical? A: Yes. Both parts carry UL94 V-0 flammability rating, ROHS3 compliance, and REACH Unaffected status. Moisture sensitivity level is identical (MSL 1 - Unlimited).

Q: Why is the original part obsolete? A: Product obsolescence reflects manufacturer lifecycle decisions. The active substitute provides equivalent functionality with current manufacturing support and supply availability.

Q: What are the electrical performance limits? A: Both parts are rated for 20A continuous current at 800V maximum voltage across the operating temperature range of -55°C to 125°C.
