Substitute Part Grouping Explanation

The TE Connectivity AMP Connectors 6-147105-2 qualifies as a functional substitute based on the following critical parameters:

Matching Parameters:

24-position receptacle configuration
0.100" (2.54mm) mating pitch
2-row layout with 0.100" (2.54mm) row spacing
Surface mount termination
Female socket contact type
Push-pull fastening mechanism
Gold-plated mating contacts
2A current rating
UL94 V-0 flammability rating
Board-to-board application compatibility

Substitution Basis: Both connectors share identical mechanical and electrical interface specifications for mating with complementary plug connectors. The core dimensional and contact parameters ensure physical and electrical interchangeability in the same PCB footprint and circuit application.

Engineering Selection Recommendations

The TE Connectivity 6-147105-2 is the designated substitute for the obsolete 3M 966224-2000-AR-PR. Selection is based on:

Product Status: The 3M part is obsolete with no active manufacturing. The TE Connectivity alternative maintains active production status, ensuring long-term availability and supply chain continuity.

Compliance & Certifications: Both parts carry UL94 V-0 flammability certification and MSL 1 moisture sensitivity rating. The TE Connectivity part additionally provides RoHS compliance documentation.

Operating Envelope: The TE Connectivity substitute supports an extended operating temperature range (-65°C ~ 125°C) compared to the original part (-25°C ~ 105°C), providing broader thermal margin for applications within the original specification window.

Interface Compatibility: Identical mating pitch, row spacing, contact configuration, and fastening mechanism ensure direct mechanical and electrical compatibility with existing complementary connectors and PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 6-147105-2 directly replace the 3M 966224-2000-AR-PR in existing designs?

A: Yes. Both connectors share identical mating pitch (0.100"), row spacing (0.100"), position count (24), and fastening mechanism (push-pull). The PCB footprint and mating interface are compatible with the same complementary plug connectors.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer series designation (3M 966 vs. TE Connectivity AMPMODU Mod IV), insulation material composition (thermoplastic vs. polyester glass-filled), contact material (copper alloy vs. phosphor bronze), and operating temperature range extension in the TE part. The TE substitute also provides RoHS compliance certification.

Q: Are there any packaging considerations when switching to the substitute part?

A: The TE Connectivity 6-147105-2 is supplied in Tape & Reel (TR) packaging, whereas the original 3M part packaging specification was not provided. Verify that TR packaging is compatible with your assembly process and equipment.

Q: Does the gold contact finish thickness difference affect interchangeability?

A: Both parts feature gold-plated mating contacts meeting the 0.100" pitch interface specification. The TE part specifies 30.0µin (0.76µm) gold thickness versus flash plating on the 3M part. Both finishes are suitable for the 2A current rating and 1000VDC application envelope.

Q: What is the voltage rating for the TE Connectivity substitute?

A: The TE Connectivity 6-147105-2 voltage rating was not specified in the provided data. The original 3M part is rated for 1000VDC. Consult TE Connectivity technical documentation to confirm voltage rating compatibility for your specific application.
