Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 70079-303 is determined by the following critical parameters:

• Connector Position Count: Must be 9 positions to ensure mechanical fit and signal routing compatibility
• Contact Configuration: Female socket type required for mating interface consistency
• Color Specification: Gray housing maintains visual identification and assembly standards
• Manufacturer Source: Amphenol ICC (FCI) maintains design and performance consistency
• Product Category: Backplane connector classification ensures functional equivalence

The substitute part 70079-303LF meets all these criteria while incorporating a backpanel kit with cover assembly, representing a functional variant within the same connector family.

Parameter Comparison

Engineering Selection Recommendations

Both the 70079-303 and 70079-303LF are manufactured by Amphenol ICC (FCI) and maintain identical electrical and mechanical specifications for the core 9-position female socket connector interface. Selection between these parts should be based on assembly requirements:

• 70079-303: Select when a standard termination kit configuration is required without integrated backpanel cover assembly
• 70079-303LF: Select when backpanel integration with protective cover is specified in the design, as this variant includes three-piece kit assembly

Both parts maintain new original stock status and are suitable for direct substitution where the kit configuration difference does not impact system design requirements.

Frequently Asked Questions (FAQ)

Q: Can 70079-303 and 70079-303LF be used interchangeably in the same application?

A: Both parts share identical 9-position female socket connector specifications. Interchangeability depends on whether the backpanel cover assembly included in the 70079-303LF is required by your design. If the cover is not specified, the 70079-303 provides equivalent connector functionality.

Q: What is the primary difference between these two part numbers?

A: The 70079-303LF includes a backpanel kit with protective cover assembly (3-piece configuration), while the 70079-303 is a standard termination kit. The core connector interface remains identical.

Q: Are both parts from the same manufacturer?

A: Yes, both parts are manufactured by Amphenol ICC (FCI), ensuring consistent design standards and performance characteristics.

Q: What connector positions do these parts support?

A: Both parts are configured for 9-position connector applications with female socket contacts in gray.

Q: How should I determine which part to order for my application?

A: Review your design specifications for backpanel assembly requirements. If a protective cover is specified, use 70079-303LF. If only the termination kit is required, use 70079-303. Both maintain adequate stock availability.
