Molex 0340910004 Rectangular Connector Plug Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0340910004 is a 3-position rectangular connector plug housing with a 0.177" (4.50mm) pitch, designed for free-hanging in-line applications. This component is part of the MX150 34091 series and features a green polyamide insulation body with male blade contacts and a locking ramp fastening mechanism. The part is Active in product status and maintains full RoHS3 and REACH compliance. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector housing specification, allowing for interchangeability in applications where color differentiation or inventory availability necessitates alternative part selection.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0340910004 are identified based on strict equivalence of the following critical parameters:

• Connector type (Plug)
• Number of positions (3)
• Pitch specification (0.177" / 4.50mm)
• Contact type (Male Blade)
• Mounting configuration (Free Hanging In-Line)
• Contact termination method (Crimp)
• Fastening mechanism (Locking Ramp)
• Insulation material (Polyamide/Nylon)
• Operating temperature range (-40°C ~ 125°C)
• Terminal Position Lock (TPA) feature

The primary variable among substitute parts is the housing color, which does not affect electrical or mechanical compatibility. All substitute parts maintain identical series designation (MX150 34091), product status (Active), and regulatory compliance (RoHS3, REACH).

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0340910004 and 0340910003 are Active products with identical electrical and mechanical specifications. Selection between these parts should be based on:

• Application-specific color coding requirements or system design standards
• Current inventory availability and lead time considerations
• Existing connector color schemes in the assembly or system

Both parts maintain full RoHS3 compliance and REACH compliance status, with MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling. The interchangeability of these parts is complete from an electrical and mechanical standpoint, with housing color as the sole differentiating factor.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0340910003 (brown) be used as a direct replacement for the 0340910004 (green)?

A: Yes. Both parts are electrically and mechanically identical. They share the same 3-position configuration, 0.177" pitch, male blade contact type, crimp termination, locking ramp fastening, and operating temperature range. The only difference is housing color.

Q: Are there any compatibility issues when substituting between these parts?

A: No compatibility issues exist from an electrical or mechanical perspective. Both parts are designed for the same MX150 34091 series and maintain identical contact specifications and mounting configurations.

Q: Do these connector housings include contacts?

A: No. Both the 0340910004 and 0340910003 are housing-only components. Contacts must be sourced separately and installed via crimp termination.

Q: What is the significance of the Terminal Position Lock (TPA) feature?

A: The Terminal Position Lock (TPA) feature provides mechanical assurance that contacts are properly seated within the housing, preventing accidental contact displacement during assembly or operation.

Q: Are there any storage or handling requirements for these parts?

A: Both parts carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints. Standard component storage practices apply.

Q: What is the base product number, and how does it relate to these part numbers?

A: The base product number is 034091. The full part numbers 0340910004 and 0340910003 are derived from this base, with the final digits indicating specific variants (housing color in this case).
