Parameter Comparison

Engineering Selection Recommendations

1-103735-2 (TE Connectivity AMP Connectors AMPMODU MTE Series)

Primary selection for applications requiring the extended lower temperature operating range of -65°C. This part maintains ROHS3 compliance and REACH affected status. The 4-wall shrouding provides enhanced mechanical protection. Brass contact material with 30.0µin gold plating thickness meets automotive and telecommunications specifications.

0705430012 (Molex SL 70543 Series)

Suitable for applications operating within -40°C to 105°C temperature range. This part is ROHS3 compliant and REACH unaffected, offering regulatory advantage in certain supply chain contexts. The 4-wall shrouding matches the main part configuration. Phosphor bronze contact material with 15.0µin gold plating thickness provides cost optimization. Voltage rating of 250V is specified for this part. Current rating is not specified in available documentation.

76384-313LF (Amphenol ICC Dubox™ Series)

Suitable for applications requiring extended upper temperature operation to 125°C. This part is RoHS compliant and REACH affected. The 2-wall shrouding provides reduced mechanical protection compared to the main part. Copper alloy contact material with 30.0µin gold plating thickness and GXT™ finish technology matches the main part's contact finish thickness. Current rating of 3A aligns with the main part specification.

All three parts maintain UL94 V-0 flammability rating, unlimited moisture sensitivity level (MSL 1), and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0705430012 be used as a direct replacement for the TE Connectivity 1-103735-2?

A: The Molex 0705430012 shares critical electrical and mechanical parameters including 13-position, 0.100" pitch, through-hole solder termination, and gold-plated male pin contacts. Both parts feature 4-wall shrouding, UL94 V-0 rating, and unlimited moisture sensitivity. The primary difference is the operating temperature range: the Molex part operates from -40°C to 105°C, while the TE part extends to -65°C. Selection depends on the minimum operating temperature requirement of the application.

Q: What is the difference between the 4-wall and 2-wall shrouding on the Amphenol ICC 76384-313LF?

A: Shrouding wall configuration affects mechanical protection and mating force characteristics. The 4-wall shrouding on the TE Connectivity 1-103735-2 and Molex 0705430012 provides complete perimeter protection. The 2-wall shrouding on the Amphenol ICC 76384-313LF provides reduced mechanical protection but may offer different mating force profiles. Physical compatibility with mating connectors must be verified based on specific application requirements.

Q: Are there voltage rating differences between these parts?

A: The Molex 0705430012 specifies a 250V voltage rating. The TE Connectivity 1-103735-2 and Amphenol ICC 76384-313LF do not have voltage ratings specified in available documentation. For applications with specific voltage requirements, the Molex part provides explicit voltage specification.

Q: What is the significance of the contact finish thickness differences?

A: The TE Connectivity 1-103735-2 and Amphenol ICC 76384-313LF both specify 30.0µin (0.76µm) gold plating thickness on mating contacts. The Molex 0705430012 specifies 15.0µin (0.38µm) thickness. Thicker plating generally provides enhanced corrosion resistance and contact durability over extended service life. Selection should consider environmental exposure and expected connector mating cycles.

Q: Which part is suitable for automotive applications?

A: All three parts list automotive applications in their specifications. The TE Connectivity 1-103735-2 explicitly includes automotive in its application list. The Molex 0705430012 includes automotive and industrial applications. The Amphenol ICC 76384-313LF does not specify applications in available documentation. For automotive-specific requirements, verify compliance with relevant automotive standards and supplier qualification requirements.

Q: What is the difference between ROHS3 Compliant and RoHS Compliant status?

A: The TE Connectivity 1-103735-2 and Molex 0705430012 are specified as ROHS3 Compliant, indicating compliance with the third iteration of the Restriction of Hazardous Substances directive. The Amphenol ICC 76384-313LF is specified as RoHS Compliant without version specification. Both statuses indicate compliance with hazardous substance restrictions, though ROHS3 represents the current regulatory standard.

Q: Can these parts be used interchangeably in existing designs?

A: Interchangeability depends on specific design parameters including operating temperature range, shrouding configuration, contact finish requirements, and mating connector compatibility. The 13-position, 0.100" pitch, through-hole solder termination, and gold-plated male pin contacts are common across all three parts. Physical dimensions, particularly insulation height and overall contact length, vary between parts and must be verified against PCB layout and mating connector specifications before substitution.
