Molex 1600733111 Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The Molex 1600733111 is a 3-position receptacle housing for rectangular connectors with a 0.177" (4.50mm) pitch. This component is part of the MX150 160073 series and is designed for free-hanging, in-line applications requiring crimp termination. The housing is sealed, constructed from glass-filled polyamide (PA6), and rated for operating temperatures from -40°C to 125°C. This part is currently active in production with full inventory availability. Equivalent substitute parts may be required due to supply chain considerations, packaging preferences, or project-specific sourcing requirements.

Substitute Part Grouping Explanation

The substitute part 1600733102 is electrically and mechanically equivalent to the main part 1600733111 based on the following critical parameters:

Identical connector type (Receptacle) and contact type (Female Socket)
Matching position count (3 positions) and pitch specification (0.177" / 4.50mm)
Same mounting configuration (Free Hanging, In-Line) and termination method (Crimp)
Identical fastening type (Latch Holder), color (Gray), and sealed feature
Matching insulation material (Polyamide PA6, Glass Filled) and temperature rating (-40°C to 125°C)
Equivalent compliance certifications (ROHS3, MSL 1, REACH Unaffected)

The primary difference between these parts is packaging: 1600733111 is supplied in standard packaging, while 1600733102 is supplied in bulk packaging. Both parts share the same base product number (160073) and series designation (MX150 160073), confirming their functional equivalence.

Engineering Selection Recommendations

Both the Molex 1600733111 and 1600733102 are active production parts with full ROHS3 compliance and REACH unaffected status, making them suitable for applications requiring regulatory compliance. The selection between these parts should be based on packaging requirements and inventory availability rather than electrical or mechanical performance, as all functional parameters are identical.

The 1600733111 with standard packaging is appropriate for applications requiring controlled unit quantities and standard distribution channels. The 1600733102 with bulk packaging is suitable for high-volume manufacturing operations or applications where bulk sourcing provides cost or logistics advantages. Both parts carry MSL 1 (Unlimited) moisture sensitivity, eliminating special storage or handling requirements.

Frequently Asked Questions (FAQ)

Q: Are the Molex 1600733111 and 1600733102 fully interchangeable?

A: Yes. Both parts are functionally equivalent across all electrical and mechanical parameters, including connector type, position count, pitch, mounting configuration, termination method, and operating temperature range. The only difference is packaging format.

Q: What is the difference between standard and bulk packaging for these parts?

A: Standard packaging (1600733111) is used for typical distribution and smaller order quantities. Bulk packaging (1600733102) is used for high-volume orders and direct manufacturing integration. The connector housing itself is identical in both cases.

Q: Can I substitute 1600733102 for 1600733111 in an existing design?

A: Yes. Since all functional parameters match exactly, 1600733102 can be used as a direct substitute for 1600733111 without design modifications or compatibility concerns.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the 1600733111 and 1600733102 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: What is the moisture sensitivity level for these connector housings?

A: Both parts carry MSL 1 (Unlimited), indicating no special moisture control or baking requirements during storage or handling.

Q: Do these housings include contacts?

A: No. Both the 1600733111 and 1600733102 are housings only. Contacts must be sourced separately and installed using the crimp termination method.
