Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0791077010 is determined by strict alignment with the following core parameters:

• Connector Type & Contact Configuration: Must be a receptacle with female socket contacts
• Position Count & Row Configuration: Exactly 22 positions arranged in 2 rows
• Pitch Specification: 0.079" (2.00mm) mating pitch and row spacing
• Mounting & Termination: Through-hole mounting with solder termination
• Fastening Mechanism: Push-pull fastening system
• Contact Finish: Gold-plated mating surface

The TE Connectivity AMP Connectors part number 3-1734506-4 meets all substitution criteria. Both connectors share identical mechanical and electrical interface specifications, enabling direct functional replacement in applications requiring 22-position rectangular connectors with 2.00mm pitch spacing.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 3-1734506-4 directly replace the Molex 0791077010 in existing designs?

A: Yes. Both connectors share identical mechanical interfaces (22 positions, 2.00mm pitch, through-hole mounting, push-pull fastening) and electrical contact specifications (gold-plated female sockets, phosphor bronze contacts). Direct substitution is functionally compatible.

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

A: The primary differences are operational temperature range (Molex -55°C to 125°C vs. TE Connectivity -40°C to 105°C), voltage rating (Molex 125V vs. TE Connectivity 250VAC), packaging format (Molex tube vs. TE Connectivity tray), and insulation material composition (Molex glass-filled vs. TE Connectivity standard thermoplastic). Verify these specifications against your application requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both the Molex 0791077010 and TE Connectivity 3-1734506-4 are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level), making them suitable for standard manufacturing and storage conditions.

Q: What is the significance of the packaging difference?

A: Molex 0791077010 is supplied in tube packaging; TE Connectivity 3-1734506-4 is supplied in tray packaging. This affects handling, storage, and automated assembly compatibility. Verify your assembly equipment specifications before selecting based on packaging format.

Q: Which part should I select for high-temperature applications?

A: The Molex 0791077010 supports operation up to 125°C, making it suitable for higher-temperature environments. The TE Connectivity 3-1734506-4 is rated to 105°C maximum. Select based on your specific operating temperature requirements.
