Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0349002001 are qualified based on the following critical parameters that must remain constant:

• Connector Type: Receptacle
• Contact Type: Female Blade Socket
• Number of Positions: 2
• Pitch: 0.157" (4.00mm)
• Number of Rows: 1
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Fastening Type: Latch Holder
• Features: Sealed
• Series: MXP120 34900
• RoHS Status: ROHS3 Compliant

The substitute parts 0349002101, 0349002120, and 0349002121 maintain all critical electrical and mechanical parameters. Variations in color (yellow to black) and operating temperature ranges do not affect functional interchangeability within the MXP120 34900 series architecture.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: Molex 0349002101

The 0349002101 is the direct functional equivalent with active product status. It maintains identical electrical and mechanical specifications to the obsolete 0349002001, including yellow color matching. This part is recommended as the first-choice replacement for direct substitution in existing designs.

Alternative Substitutes: Molex 0349002120 and 0349002121

Both 0349002120 and 0349002121 are parametric equivalents with active product status and full ROHS3 compliance. These parts differ only in color (black instead of yellow) and operating temperature range (-40°C to 155°C versus -40°C to 125°C for the main part). Selection between these alternatives depends on application requirements for color coding and thermal operating conditions. Both parts maintain identical mechanical fit and electrical performance within the MXP120 34900 series.

Frequently Asked Questions (FAQ)

Q: Can 0349002101 be used as a direct replacement for 0349002001?

A: Yes. The 0349002101 maintains all critical electrical and mechanical parameters including connector type, contact configuration, pitch, mounting method, and termination type. The primary difference is product status (active versus obsolete).

Q: What is the difference between 0349002101 and 0349002120/0349002121?

A: The 0349002101 is yellow; 0349002120 and 0349002121 are black. Additionally, 0349002120 and 0349002121 support operating temperatures to 155°C compared to 125°C for 0349002101. All three parts are functionally equivalent within the MXP120 34900 series.

Q: Are color differences between substitute parts significant for interchangeability?

A: Color is a visual identifier and does not affect electrical or mechanical interchangeability. Selection should be based on application requirements for color coding or visual identification.

Q: Do all substitute parts maintain the same packaging format?

A: The main part 0349002001 is listed with no specified packaging. All substitute parts (0349002101, 0349002120, 0349002121) are supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Are contacts included with these connector housings?

A: No. All parts in this series (main and substitutes) are housings only. Female blade socket contacts must be ordered separately.

Q: What compliance certifications apply to these parts?

A: All parts maintain ROHS3 compliance and MSL rating of 1 (unlimited moisture sensitivity level). The substitute parts 0349002101, 0349002120, and 0349002121 additionally carry REACH Unaffected status.
