Parameter Comparison

Engineering Selection Recommendations

Both the 70079-312 and 70079-312LF are manufactured by Amphenol ICC (FCI) and share identical core specifications for 21-position receptacle connectors with female sockets in gray. Selection between these parts should be based on packaging requirements and inventory availability. The 70079-312LF includes a backpanel cover assembly (3-piece kit), which may provide additional mechanical protection or integration benefits depending on application requirements. The 70079-312 standard kit configuration offers alternative packaging for applications where the cover assembly is not required or sourced separately.

Frequently Asked Questions (FAQ)

Q: Can the 70079-312LF directly replace the 70079-312 in existing designs?

A: Yes. Both parts are 21-position receptacle connectors with female sockets manufactured by Amphenol ICC (FCI). The primary difference is packaging configuration: the 70079-312LF includes a backpanel cover assembly, while the 70079-312 is supplied as a standard connector kit. Electrical and mechanical compatibility is maintained across both part numbers.

Q: What is the significance of the "LF" suffix in the 70079-312LF part number?

A: The "LF" designation indicates a variant configuration that includes additional components (backpanel cover, 3-piece assembly). This suffix does not affect the core connector specifications but identifies a different kit assembly level.

Q: Are there any restrictions on interchangeability between these parts?

A: Interchangeability is determined by application requirements for the backpanel cover assembly. If the cover is required for mechanical integration or environmental protection, the 70079-312LF is the appropriate selection. If the cover is not needed or sourced separately, the 70079-312 provides equivalent connector functionality.

Q: How should part selection be prioritized when both options are available?

A: Selection should be based on specific application packaging requirements and inventory availability. Verify whether the backpanel cover assembly (included in 70079-312LF) is necessary for your mechanical design before part selection.
