3M 3399-G600 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The 3M 3399-G600 is a 26-position rectangular receptacle connector designed for IDC (Insulation Displacement Contact) termination with ribbon cable. This connector features gold-plated contacts, a polarizing key for proper orientation, and supports wire gauges from 26-28 AWG in both stranded and solid configurations. The product is Active status and RoHS compliant, making it suitable for applications requiring reliable ribbon cable interconnection in industrial and commercial equipment.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained, ensuring functional compatibility while providing alternative sourcing options.

Substitute Part Grouping Explanation

The Amphenol ICC (FCI) part number 86130263130345E1LF qualifies as a substitute for the 3M 3399-G600 based on the following critical parameters:

• Connector Configuration: Both are 26-position rectangular receptacles with identical 0.100" (2.54mm) pitch and 2-row layout
• Termination Method: Both utilize IDC technology for ribbon cable attachment
• Contact System: Both feature gold-plated female socket contacts
• Wire Compatibility: The substitute supports 28 AWG, which falls within the main part's 26-28 AWG range
• Mounting: Both are free-hanging, in-line configurations
• Polarization: Both include polarizing keys for correct orientation
• Compliance: Both are RoHS compliant with MSL 1 rating

The substitute maintains functional equivalence for applications requiring 26-position IDC ribbon cable connections with gold contact reliability.

Parameter Comparison

Engineering Selection Recommendations

Both the 3M 3399-G600 and Amphenol ICC 86130263130345E1LF are Active products with full RoHS compliance and MSL 1 ratings, indicating equivalent environmental and regulatory qualification. Selection between these parts should be based on:

• Availability: The Amphenol ICC part shows higher inventory (1383 pcs vs. 871 pcs)
• Wire Gauge Requirements: The main part supports 26-28 AWG; the substitute is specified for 28 AWG. Applications requiring 26 AWG wire should verify compatibility with the substitute
• Additional Features: The substitute includes strain relief in addition to the polarizing key, providing enhanced mechanical protection
• Fastening: The substitute includes a latch holder mechanism, whereas the main part does not specify this feature

Both parts are suitable for production use in equivalent ribbon cable interconnection applications.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 86130263130345E1LF directly replace the 3M 3399-G600 in existing designs?

A: Yes, for applications using 28 AWG ribbon cable. The connector pitch, row configuration, IDC termination method, and contact finish are identical. If your design uses 26 AWG wire, verify that the substitute's 28 AWG specification meets your application requirements.

Q: What is the significance of the 0.100" pitch specification?

A: The 0.100" (2.54mm) pitch defines the center-to-center spacing between adjacent contacts. Both the main part and substitute share this pitch, ensuring mechanical and electrical compatibility with mating connectors and PCB layouts designed for this standard.

Q: Are both connectors suitable for the same ribbon cable types?

A: Both connectors are designed for IDC termination with ribbon cable. The main part accommodates 26-28 AWG in stranded or solid form; the substitute is specified for 28 AWG. Confirm your ribbon cable gauge matches the selected connector.

Q: What does the polarizing key feature provide?

A: The polarizing key is a mechanical feature that prevents incorrect connector orientation during assembly, ensuring proper pin alignment and preventing damage from reversed insertion.

Q: How do the RoHS and MSL ratings affect component selection?

A: Both parts are RoHS compliant and carry MSL 1 (Unlimited) ratings, indicating they meet environmental regulations and have no moisture sensitivity restrictions. They are equivalent in regulatory and storage requirements.

Q: What is the difference between "Feed Through" and "Strain Relief" features?

A: Feed Through allows the connector to pass signals through without blocking access. Strain Relief provides mechanical support to the cable at the connector interface, reducing stress on the IDC contacts during flexing or movement.
