Substitute Part Grouping Explanation

Substitution of the M80-4T12642FC is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Arrangement: 26 positions in 2-row configuration
• Mating Pitch & Row Spacing: 0.079" (2.00mm) pitch with 0.079" (2.00mm) row spacing
• Mounting & Termination: Through-hole solder termination with screw-lock fastening
• Electrical Performance: 2.2A current rating and 800V voltage rating
• Environmental Specifications: -55°C to 125°C operating temperature range
• Contact Materials & Finishes: Beryllium copper contacts with gold mating finish and tin post finish
• Insulation Properties: Polyphenylene sulfide (PPS) glass-filled insulation with UL94 V-0 rating

The M80-4T12642FD meets all these criteria as an active equivalent within the same Datamate J-Tek series.

Frequently Asked Questions (FAQ)

Q: Are the M80-4T12642FC and M80-4T12642FD mechanically interchangeable?

A: Yes. Both connectors share identical mounting type (through-hole), pitch (0.079" / 2.00mm), row spacing (0.079" / 2.00mm), and fastening method (screw lock). Physical dimensions, including insulation height (0.205" / 5.20mm) and mated stacking heights (7.3mm, 7.55mm), are identical.

Q: What is the difference between these two part numbers?

A: The primary difference is product status. The M80-4T12642FC is obsolete, while the M80-4T12642FD is active. All electrical, mechanical, and environmental specifications are identical. The M80-4T12642FD carries updated compliance documentation (ECCN: EAR99 vs. OBSOLETE designation).

Q: Can I use the M80-4T12642FD in existing designs originally specified for the M80-4T12642FC?

A: Yes. The M80-4T12642FD is a direct functional equivalent with no design modifications required. PCB layouts, mating connector specifications, and assembly processes remain unchanged.

Q: Are there any compliance or certification differences?

A: Both parts maintain ROHS3 compliance and REACH Unaffected status. The M80-4T12642FD carries current ECCN classification (EAR99) with active HTSUS code (8536.69.4040), while the obsolete M80-4T12642FC carries legacy designations.

Q: What is the contact material and finish specification?

A: Both connectors use beryllium copper contacts with gold plating on mating surfaces (12.0µin / 0.30µm thickness) and tin plating on post surfaces (137.8µin / 4.60µm thickness).

Q: Are these connectors suitable for automotive applications?

A: Yes. Both parts are rated for automotive, general purpose, and military applications with operating temperature range of -55°C to 125°C and UL94 V-0 flammability rating.
