Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 960222-6303-AR is determined by the following critical parameters:

• 22-position receptacle configuration with female socket contacts
• 0.100" (2.54mm) mating pitch and row spacing
• Two-row board-to-board layout
• Through-hole solder termination with push-pull fastening
• Gold-plated mating contacts
• UL94 V-0 flammability rating
• Thermoplastic insulation material

The substitute parts Amphenol ICC (FCI) 87606-311LF and 89891-311LF meet these core electrical and mechanical parameters. Both are active products in the Dubox™ series with identical position count, pitch, row configuration, and termination method. The 89891-311LF variant provides bottom or top entry connector options, offering additional design flexibility.

Parameter Comparison

Engineering Selection Recommendations

Both Amphenol ICC (FCI) substitute parts are active products with current manufacturing support, addressing the obsolescence of the 3M 960222-6303-AR. The 87606-311LF and 89891-311LF connectors maintain mechanical and electrical compatibility through identical position count, pitch, row spacing, and termination specifications.

The Amphenol ICC substitutes provide enhanced material specifications with glass-filled thermoplastic insulation and phosphor bronze contacts, offering improved durability compared to the original part. Both substitutes carry RoHS compliance and REACH affected status, meeting modern regulatory requirements.

The 89891-311LF variant offers additional design flexibility through bottom or top entry connector configuration, providing options for different PCB layout requirements while maintaining full electrical and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Are the Amphenol ICC 87606-311LF and 89891-311LF fully compatible with the 3M 960222-6303-AR?

A: Both parts maintain compatibility through identical electrical and mechanical specifications: 22-position receptacle configuration, 0.100" (2.54mm) pitch, two-row layout, through-hole solder termination, and push-pull fastening. Physical dimensions and mating interface are equivalent.

Q: What is the difference between the 87606-311LF and 89891-311LF?

A: The primary difference is connector entry orientation. The 87606-311LF is a standard receptacle, while the 89891-311LF provides bottom or top entry options. Both maintain identical electrical ratings, position count, and pitch specifications.

Q: Do the substitute parts meet current compliance standards?

A: Yes. Both Amphenol ICC substitutes are RoHS compliant and REACH affected, meeting current regulatory requirements. The original 3M part does not specify these compliance statuses.

Q: What are the contact material differences?

A: The 3M 960222-6303-AR uses copper alloy contacts, while the Amphenol ICC substitutes use phosphor bronze contacts. Both materials are suitable for the specified 2A current rating and 1000VDC voltage rating.

Q: Are there packaging differences between the original and substitute parts?

A: The 3M part does not specify packaging, while both Amphenol ICC substitutes are supplied in tube packaging. This does not affect electrical or mechanical compatibility.
