Molex 0340620045 Equivalent & Substitute Parts

Part Overview

The Molex 0340620045 is a 2-position rectangular connector receptacle housing from the MX150 34062 series, designed for 5.00mm pitch applications. This connector features a female socket configuration with crimp termination and latch holder fastening, suitable for free-hanging in-line mounting. The part is ROHS3 compliant and currently in active production status with 1147 units in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the MX150 34062 series, allowing for component interchangeability in applications where specific design constraints permit variation in color or temperature rating.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0340620045 are qualified based on the following core parameters that must remain constant:

• Connector Type: Receptacle
• Contact Type: Female Socket
• Number of Positions: 2
• Pitch: 0.197" (5.00mm)
• Number of Rows: 1
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Fastening Type: Latch Holder
• Features: Connector Position Assurance (CPA), Sealed
• Insulation Material: Polyamide (PA6), Nylon 6 base composition
• Product Status: Active
• RoHS Status: ROHS3 Compliant

Variations permitted in substitute parts include color and maximum operating temperature, provided the application requirements do not mandate specific thermal or visual specifications. All substitute parts belong to the MX150 34062 series and maintain mechanical and electrical compatibility with the main part.

Parameter Comparison

Engineering Selection Recommendations

All four parts maintain active product status and ROHS3 compliance, qualifying them for use in applications requiring regulatory adherence. Selection between the main part (0340620045) and its substitutes depends on application-specific requirements:

Part 0340620037 is functionally identical to the main part with matching operating temperature range (-40°C ~ 125°C) and color specification (Gray). This part offers the highest inventory availability at 4431 units.

Part 0340620051 differs in color (Black) and provides an extended operating temperature range (-40°C ~ 155°C). Selection of this part is appropriate only when thermal performance above 125°C is required or when black housing is specified in the design.

Part 0340620054 maintains gray color matching the main part while providing extended operating temperature capability (-40°C ~ 155°C). This part is suitable for applications requiring thermal performance beyond 125°C without color constraint changes.

Frequently Asked Questions (FAQ)

Q: Can 0340620037 be used as a direct replacement for 0340620045?

A: Yes. Both parts share identical electrical and mechanical specifications, including 2-position configuration, 5.00mm pitch, crimp termination, and operating temperature range of -40°C to 125°C. Both are gray and ROHS3 compliant.

Q: What is the difference between 0340620051 and the main part?

A: The 0340620051 differs in two parameters: housing color (Black instead of Gray) and maximum operating temperature (155°C instead of 125°C). All other specifications remain equivalent. Use this part only when thermal performance above 125°C is required or when black housing is specified.

Q: Can I use 0340620054 in place of 0340620045?

A: Yes, with consideration of thermal requirements. The 0340620054 maintains gray color and all mechanical specifications but extends the maximum operating temperature to 155°C. If your application operates within the -40°C to 125°C range, both parts are functionally equivalent.

Q: Are all substitute parts from the same manufacturer?

A: Yes. All parts are manufactured by Molex and belong to the MX150 34062 series, ensuring design consistency and compatibility within the connector family.

Q: What does "Connector Position Assurance (CPA)" mean?

A: CPA is a feature that prevents mating of incomplete connector assemblies by blocking engagement until all contacts are properly seated. All parts in this comparison include this safety feature.

Q: Do these connectors include contacts?

A: No. All parts in this comparison are housings only. Contacts must be sourced separately and crimped into the housing according to Molex specifications.
