• Number of rows (1)
• Pitch spacing (0.100" / 2.54mm)
• Mounting method (Through Hole)
• Termination method (Solder)
• Fastening type (Push-Pull)
• Contact geometry (Square shape, mating length 0.228", post length 0.126", overall length 0.465")
• Insulation dimensions (Height 0.110")
• Insulation material (PBT)
• Shrouding configuration (Unshrouded)
• Style classification (Board to Board or Cable)

Electrical and Environmental Parameters:

• Moisture Sensitivity Level (MSL 1 - Unlimited)
• Contact material composition
• Contact finish specifications

The substitute part 826646-2 maintains full mechanical and dimensional compatibility with the 966443-2 while offering active product status and enhanced compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The 826646-2 is the direct equivalent substitute for the obsolete 966443-2. Both connectors share identical mechanical dimensions, contact geometry, pitch spacing, and mounting characteristics within the AMPMODU Mod II series.

Product Status Consideration: The 966443-2 carries obsolete product status, indicating discontinued manufacturing and limited availability. The 826646-2 maintains active product status with significantly higher inventory availability (26,022 pieces in stock versus 733 pieces for the obsolete part), ensuring reliable supply chain continuity.

Compliance and Certification Advantages: The 826646-2 provides enhanced compliance certifications not specified for the 966443-2:

• ROHS3 compliance certification
• UL94 V-0 material flammability rating
• Documented operating temperature range (-65°C ~ 105°C)
• Specified current rating (5A)

Contact Material Differences: The 966443-2 uses copper alloy contacts with tin-lead post finish, while the 826646-2 uses brass contacts with tin post finish. Both configurations maintain gold mating surface finish and are compatible with standard PCB through-hole assembly processes.

For new designs and production applications, the 826646-2 is the appropriate selection. For legacy system repairs requiring exact historical component matching, the 966443-2 remains available in limited quantities.

Frequently Asked Questions (FAQ)

Q: Are the 966443-2 and 826646-2 mechanically interchangeable?

A: Yes. Both connectors maintain identical pitch spacing (0.100" / 2.54mm), contact geometry, mounting type (through-hole solder), and overall dimensions. They are direct mechanical equivalents within the AMPMODU Mod II series.

Q: What is the primary reason to substitute the 966443-2?

A: The 966443-2 is classified as obsolete product status with limited inventory (733 pieces). The 826646-2 is an active product with substantially higher availability (26,022 pieces), ensuring long-term supply chain reliability.

Q: Do the contact material differences between the two parts affect compatibility?
