Key Parameters

Substitute Part Grouping Explanation

The Sullins Connector Solutions NPPN042FFKS-RC qualifies as a substitute based on the following critical parameters:

Matching Parameters:

• 8-position configuration
• 0.079" (2.00mm) mating pitch
• 2-row layout with 0.079" (2.00mm) row spacing
• Surface mount termination
• Gold contact finish on mating surface
• Square contact shape
• Phosphor bronze contact material
• Push-pull fastening type
• Black insulation color
• UL94 V-0 flammability rating
• ROHS3 compliance
• MSL 1 (Unlimited moisture sensitivity level)

Substitution Logic: The NPPN042FFKS-RC maintains electrical and mechanical compatibility through identical pitch spacing, contact configuration, and surface mount footprint. Both connectors support the same mating interface geometry and contact arrangement, enabling direct PCB layout compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0791099208 and Sullins NPPN042FFKS-RC maintain ROHS3 compliance and MSL 1 ratings, ensuring compatibility with standard manufacturing and storage protocols. The Molex part provides a wider operating temperature range (-55°C to 125°C) compared to the Sullins substitute (-40°C to 105°C), which may be a determining factor for applications requiring extended temperature performance. The Sullins connector offers a higher current rating (2A versus 1A), providing additional margin for power delivery applications. Both parts are active products with established supply availability.

Frequently Asked Questions (FAQ)

Q: Can the Sullins NPPN042FFKS-RC directly replace the Molex 0791099208 on the same PCB?

A: Yes, both connectors share identical mating pitch (0.079"), row spacing (0.079"), and surface mount footprint geometry. The PCB layout remains compatible without modification.

Q: What is the primary difference between these connectors?

A: The Molex part is a receptacle connector, while the Sullins part is a header connector. Both feature identical contact arrangements and mating interfaces. The Molex part supports a wider operating temperature range (-55°C to 125°C), while the Sullins part provides higher current capacity (2A versus 1A).

Q: Are there packaging differences between these parts?

A: Yes. The Molex 0791099208 is supplied in Tape & Reel (TR) packaging, while the Sullins NPPN042FFKS-RC is supplied in Tube packaging. This affects handling and automated assembly processes.

Q: Do both connectors meet the same compliance standards?

A: Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) ratings. Both achieve UL94 V-0 flammability classification.

Q: Which part should be selected for high-temperature applications?

A: The Molex 0791099208 supports operation up to 125°C, making it suitable for applications requiring extended temperature performance. The Sullins substitute is rated to 105°C maximum.
