Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0719790204 is based on strict equivalence across the following critical parameters:

• Connector type: Receptacle with female socket contacts
• Position count and arrangement: 8 positions in 2 rows
• Mating pitch and row spacing: 0.100" (2.54mm)
• Mounting configuration: Surface mount, right-angle orientation
• Termination method: Solder
• Fastening mechanism: Push-pull
• Contact finish: Gold plating on mating surfaces
• Contact material: Phosphor bronze
• Insulation material composition and flammability rating: UL94 V-0

The TE Connectivity AMP Connectors part number 5147722-3 meets all these criteria and is designated as the manufacturer-recommended substitute.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5147722-3 is the designated substitute for the obsolete Molex 0719790204. Selection is supported by the following factors:

All critical electrical and mechanical parameters align between the two parts. The substitute maintains identical connector topology, pitch, row configuration, and contact materials. Both parts carry UL94 V-0 flammability certification and MSL 1 moisture sensitivity rating.

The TE Connectivity part offers an extended operating temperature range (-55°C to 125°C versus -40°C to 105°C), providing broader environmental compatibility. Both parts maintain RoHS compliance status, with the substitute classified as active product, ensuring ongoing availability and supply chain stability.

The substitute is available in cut tape packaging with documented inventory, supporting both new designs and legacy system maintenance.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5147722-3 directly replace the Molex 0719790204 in existing designs?

A: Yes. Both connectors share identical mating pitch (0.100"), position count (8), row configuration (2 rows), mounting type (surface mount right-angle), and contact finish (gold). Mechanical and electrical compatibility is established across all specified parameters.

Q: What are the key differences between these two parts?

A: The primary differences are product status and operating temperature range. The Molex part is obsolete; the TE Connectivity part is active. The TE Connectivity part operates from -55°C to 125°C, compared to -40°C to 105°C for the Molex part. Insulation material composition differs: Molex uses LCP (liquid crystal polymer), while TE Connectivity uses PCT (polycyclohexylenedimethylene terephthalate) with polyester.

Q: Are there packaging considerations when switching to the substitute?

A: The TE Connectivity 5147722-3 is supplied in cut tape (CT) packaging. Verify that your assembly process accommodates this packaging format. The Molex part packaging specification was not provided in the available data.

Q: Do both parts meet the same compliance standards?

A: Both parts are UL94 V-0 rated and carry MSL 1 (unlimited) moisture sensitivity classification. The Molex part is ROHS3 compliant; the TE Connectivity part is RoHS compliant. Both are classified under ECCN EAR99 and HTSUS 8536.69.4040.

Q: What is the current rating for the TE Connectivity substitute?

A: The TE Connectivity 5147722-3 is rated for 2A per contact. Current rating for the Molex 0719790204 was not specified in the available technical data.
