TE Connectivity AMP Connectors 1-1670918-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 1-1670918-1 is a 4-position rectangular connector housing designed for receptacle applications with a 0.157" (4.00mm) pitch. This connector operates across a wide temperature range of -40°C to 130°C and is sealed for environmental protection. The part is actively manufactured and RoHS compliant, making it suitable for industrial and commercial applications requiring reliable in-line connectivity. Substitute parts may be required due to inventory constraints, application-specific environmental demands, or design modifications that necessitate alternative pitch configurations or enhanced sealing capabilities.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1-1670918-1 is determined by the following critical parameters: connector type (receptacle), contact type (female socket), number of positions (4), number of rows (1), mounting type (free hanging in-line), contact termination method (crimp), and color (black). The substitute part Molex 0521170411 shares these core functional characteristics, enabling cross-application use in systems where connector housing compatibility is required. However, this substitute introduces a different pitch specification (0.098" / 2.50mm versus 0.157" / 4.00mm), which represents a design modification rather than a direct drop-in replacement. The substitute also features enhanced environmental sealing (IP67 waterproof rating) and operates within a narrower temperature range (-40°C ~ 105°C). These differences must be evaluated against specific application requirements before implementation.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 1-1670918-1 and Molex 0521170411 are active products with current manufacturing status and full RoHS compliance certifications. The primary selection criterion depends on pitch requirement compatibility. The TE Connectivity part maintains a 4.00mm pitch suitable for applications with standard spacing requirements and supports operation to 130°C. The Molex substitute operates at a reduced 2.50mm pitch, accommodating higher-density connector layouts, and provides enhanced environmental protection through IP67 waterproof sealing when mated. Selection should be based on whether the application requires the original 4.00mm pitch specification or can accommodate the 2.50mm pitch of the substitute. Temperature operating range must also be evaluated; applications requiring sustained operation above 105°C necessitate the TE Connectivity part. Both parts maintain unlimited moisture sensitivity ratings and are suitable for industrial deployment.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0521170411 be used as a direct replacement for the TE Connectivity 1-1670918-1?

A: No. While both parts share identical connector type, contact type, position count, and mounting configuration, the pitch differs significantly (4.00mm versus 2.50mm). This pitch difference means the mating interface and PCB footprint are incompatible. The Molex part requires redesign of the mating connector and circuit board layout.

Q: What are the key compatibility factors between these two parts?

A: Both parts are 4-position receptacle housings with female sockets, crimp termination, free-hanging in-line mounting, and black color. Both maintain unlimited MSL ratings and are RoHS compliant. Compatibility is limited to applications where pitch modification is acceptable.

Q: Does the Molex substitute offer any performance advantages?

A: The Molex 0521170411 provides IP67 waterproof sealing when mated, compared to the sealed design of the TE Connectivity part. This enhanced environmental protection is beneficial for applications exposed to moisture or splash conditions. However, the Molex part operates to a maximum of 105°C, compared to 130°C for the TE Connectivity part.

Q: Are there packaging differences between these parts?

A: Yes. The TE Connectivity 1-1670918-1 is supplied in bulk packaging, while the Molex 0521170411 is supplied in tray packaging. This affects handling, storage, and integration into automated assembly processes.

Q: What insulation material differences exist?

A: The TE Connectivity part uses Polyamide (PA66) Nylon 6/6, while the Molex substitute uses Polyester with glass filling. The glass-filled polyester provides enhanced mechanical strength and thermal stability in the Molex design.

Q: Can I use the TE Connectivity part in applications requiring IP67 waterproof sealing?

A: The TE Connectivity 1-1670918-1 is specified as sealed but not rated for IP67 waterproof protection. For applications requiring IP67 mated waterproof performance, the Molex 0521170411 is the appropriate selection, provided pitch modification is feasible.
