Molex 0705450141 Equivalent & Substitute Parts

Part Overview

The Molex 0705450141 is an active rectangular connector header designed for through-hole mounting in board-to-cable/wire applications. This shrouded 2-position header with 0.100" (2.54mm) pitch and gold-plated mating contacts serves general purpose, automotive, industrial, and medical applications. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility permits component variation within specified electrical and mechanical tolerances.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0705450141 and TE Connectivity 1-1871843-2 maintain active product status and comply with ROHS3 and UL94 V-0 flammability requirements. Selection between these parts should account for the following documented differences:

The Molex part operates across a wider temperature range (-40°C to 105°C) compared to the TE Connectivity substitute (-30°C to 105°C). Applications requiring operation below -30°C must use the Molex part.

The mating pitch differs by 0.002" (0.04mm), with the Molex part at 0.100" (2.54mm) and the TE Connectivity part at 0.098" (2.50mm). This variance requires mechanical compatibility verification with mating connectors or cable assemblies.

Contact finish differs: the Molex part features gold-plated mating contacts, while the TE Connectivity substitute uses tin plating. Gold plating provides enhanced corrosion resistance in harsh environments; tin plating is suitable for general purpose applications.

Both parts are ROHS3 compliant with MSL 1 rating and share identical ECCN and HTSUS classifications, supporting equivalent regulatory and logistics handling.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-1871843-2 be used as a direct replacement for the Molex 0705450141?

A: The TE Connectivity part is a manufacturer-recommended substitute with matching connector type, position count, mounting method, and shrouding. However, the 0.002" pitch difference and contact finish variation require verification of mechanical compatibility with mating connectors and assessment of environmental requirements.

Q: What is the significance of the pitch difference between these parts?

A: The Molex part has a 0.100" (2.54mm) mating pitch, while the TE Connectivity substitute has a 0.098" (2.50mm) pitch. This 0.002" difference may affect compatibility with existing cable assemblies or mating connectors. Mechanical fit must be confirmed before substitution.

Q: Does the contact finish difference affect performance?

A: The Molex part uses gold-plated mating contacts, providing superior corrosion resistance in corrosive or high-humidity environments. The TE Connectivity substitute uses tin plating, which is suitable for general purpose and controlled environments. Selection depends on application environment and reliability requirements.

Q: Are both parts suitable for automotive and medical applications?

A: The Molex 0705450141 is specified for automotive, general purpose, industrial, and medical applications. The TE Connectivity 1-1871843-2 is specified for general purpose applications. Automotive and medical applications should confirm the TE Connectivity part meets specific application standards and certifications.

Q: What is the temperature operating range difference?

A: The Molex part operates from -40°C to 105°C, while the TE Connectivity substitute operates from -30°C to 105°C. Applications requiring operation below -30°C must use the Molex part.

Q: Are both parts RoHS compliant?

A: Yes, both the Molex 0705450141 and TE Connectivity 1-1871843-2 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What packaging formats are available?

A: The Molex 0705450141 is supplied in tube packaging, while the TE Connectivity 1-1871843-2 is supplied in bulk packaging. Packaging selection may affect procurement, handling, and inventory management.
