Equivalent & Substitute Parts for Molex 0700660408

Part Overview

The Molex 0700660408 is a 4-position rectangular connector receptacle housing with 0.100" (2.54mm) pitch, designed for free-hanging in-line applications. This component features a polarizing key, female socket contacts, and operates across -40°C to 105°C. The part is classified as Active product status with 876 units currently in stock.

Substitute parts are identified when equivalent rectangular connector housings share identical functional parameters including connector type, contact type, number of positions, pitch, mounting configuration, and contact termination method. Alternative sources become necessary for supply chain continuity, inventory availability, or specific compliance requirements.

Engineering Selection Recommendations

Molex 0901230104 (C-Grid III 90123 Series)

This substitute offers expanded operating temperature range (-55°C to 105°C) compared to the main part (-40°C to 105°C), providing enhanced performance in low-temperature environments. The part carries ROHS3 compliance and REACH Unaffected status. Insulation material differs (Polyphenylene Oxide versus Polyester, Glass Filled), with PPO offering different thermal and chemical resistance characteristics. Inventory availability is significantly higher at 3467 units. Packaging is provided in Bulk format.

Amphenol ICC (FCI) 78211-004LF (Mini-PV™, Basics+ Series)

This substitute maintains identical operating temperature range (-40°C to 105°C) as the main part. The part carries RoHS compliance and REACH Affected status. Insulation material is Polyphenylene, Modified, differing from both the main part and the Molex substitute. Inventory availability is 2772 units. Packaging is provided in Bulk format. HTSUS classification matches the main part (8538.90.6000).

Both substitutes are Active status products suitable for direct component selection based on supply requirements and compliance specifications.

Frequently Asked Questions (FAQ)

Q: Can Molex 0901230104 be used as a direct replacement for Molex 0700660408?

A: Yes. Both parts share identical connector type, contact type, number of positions, pitch, mounting configuration, and contact termination. The primary differences are insulation material composition and operating temperature range. The 0901230104 extends the lower temperature limit to -55°C.

Q: What is the difference between the two substitute parts?

A: Both Molex 0901230104 and Amphenol ICC 78211-004LF meet all functional requirements for substitution. Key differences include manufacturer origin, series designation, insulation material formulation, compliance certifications (ROHS3 versus RoHS, REACH Unaffected versus REACH Affected), and inventory levels. Operating temperature ranges differ between the Molex substitute (-55°C to 105°C) and the Amphenol ICC part (-40°C to 105°C, matching the main part).

Q: Are contacts included with these connector housings?

A: No. All three parts—the main Molex 0700660408 and both substitutes—are connector housings only. Contacts must be sourced separately and are not included.

Q: Does packaging format affect compatibility?

A: Packaging format (Bulk versus other formats) does not affect electrical or mechanical compatibility. The main part is listed with no specified packaging, while both substitutes are supplied in Bulk packaging. This affects procurement and handling procedures but not functional performance.

Q: What compliance certifications should I consider for my application?

A: The Molex 0901230104 carries ROHS3 compliance and REACH Unaffected status. The Amphenol ICC 78211-004LF carries RoHS compliance and REACH Affected status. Selection depends on your application's regulatory requirements and geographic market specifications.

Q: Can I mix parts from different manufacturers in the same assembly?

A: All three parts are functionally equivalent based on provided parameters. However, assembly design considerations, mechanical fit verification, and application-specific requirements should be evaluated independently.
