Molex 1718561007 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 1718561007 is a shrouded vertical rectangular connector header designed for through-hole mounting applications. This 7-position connector operates at a 0.100" (2.54mm) pitch and features male pin contacts with gold-plated mating surfaces and tin-plated posts. The component is actively manufactured and widely used in automotive, medical, telecommunications, and general-purpose applications where board-to-board or board-to-cable interconnection is required. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements permit functional equivalents.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 1718561007 with the TE Connectivity 5-1376492-7 is based on the following alignment of critical parameters:

Both connectors share the same functional classification as shrouded vertical header connectors with 7 male pin positions designed for through-hole solder termination. Both use brass contact material with tin post plating and polyamide nylon insulation. Both are actively manufactured, ROHS3 compliant, and carry MSL 1 rating.

The primary difference lies in mating pitch specification: the Molex part operates at 0.100" (2.54mm) pitch, while the TE Connectivity substitute operates at 0.098" (2.50mm) pitch. This pitch variance of 0.002" (0.04mm) represents a 2% dimensional difference. Additionally, the TE Connectivity part features 4-wall shrouding compared to the 1-wall shrouding of the Molex part, and specifies a higher flammability rating (UL94 V-0 versus V-2).

Substitution is valid only when the receiving application can accommodate the 2.50mm pitch specification and when the enhanced shrouding and flammability characteristics do not create mechanical or thermal incompatibilities with the existing design.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 1718561007 and TE Connectivity 5-1376492-7 are actively manufactured components with ROHS3 compliance and MSL 1 rating, making them suitable for long-term procurement strategies. The TE Connectivity part offers enhanced material flammability performance (UL94 V-0) and increased shrouding protection (4-wall versus 1-wall), which may provide advantages in applications requiring higher safety margins or improved EMI shielding.

Selection between these parts must account for the 0.002" (0.04mm) pitch difference. Applications designed specifically for 2.54mm pitch spacing require the Molex part. Applications that can accommodate 2.50mm pitch spacing or that were originally designed for the TE Connectivity part may use the substitute without modification.

The mating surface finish difference (gold on Molex versus tin on TE Connectivity) reflects different contact durability profiles. Gold plating provides superior corrosion resistance and lower contact resistance over extended mating cycles, while tin plating offers cost efficiency for applications with limited mating cycles.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5-1376492-7 be used as a direct replacement for the Molex 1718561007?

A: Direct replacement is possible only if the receiving application was designed with tolerance for 2.50mm pitch spacing. The 0.002" (0.04mm) pitch difference may cause mechanical misalignment in applications designed specifically for 2.54mm pitch. Physical verification of PCB hole spacing is required before substitution.

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

A: The Molex part features 1-wall shrouding, while the TE Connectivity part features 4-wall shrouding. Four-wall shrouding provides enhanced protection against accidental contact and improved EMI containment. This difference is mechanical and does not affect electrical function, but may impact physical fit within connector housings or cable assemblies.

Q: How does the contact finish difference affect performance?

A: The Molex part uses gold-plated mating contacts, which provide superior corrosion resistance and maintain lower contact resistance across multiple mating cycles. The TE Connectivity part uses tin-plated mating contacts, which are suitable for applications with limited mating cycles and lower corrosion exposure. For applications requiring frequent mating or operation in corrosive environments, the gold-plated Molex part is preferred.

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

A: The Molex 1718561007 is specified for automotive, medical, telecommunications, and general-purpose applications. The TE Connectivity 5-1376492-7 is specified for general-purpose applications. Verification of the TE Connectivity part against specific automotive or medical qualification requirements is necessary before substitution in those application categories.

Q: What packaging formats are available for these parts?

A: The Molex 1718561007 is supplied in bulk packaging. The TE Connectivity 5-1376492-7 is supplied in cut tape (CT) packaging. Packaging format selection depends on assembly process requirements and inventory management practices.
