Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0349002002 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
• Base Product Number: 034900

The substitute parts identified (0349002102, 0349002120, 0349002121) maintain all critical electrical and mechanical parameters. Variations exist only in color (yellow vs. black) and product status (active vs. obsolete), with operating temperature ranges differing between yellow and black variants.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using Molex 0349002002, the following active substitute parts are available:

0349002102 is the direct functional equivalent with identical electrical and mechanical specifications. This part maintains the yellow color of the original and is actively manufactured with full inventory availability. It carries ROHS3 compliance and REACH unaffected status.

0349002120 and 0349002121 are parametric equivalents that differ only in color (black instead of yellow) and offer an extended operating temperature range of -40°C to 155°C compared to the original specification. Both parts are actively manufactured and carry identical compliance certifications.

Selection between these substitutes depends on application requirements regarding color coding and thermal operating range. All three substitute parts maintain functional compatibility with the original 0349002002 housing design.

Frequently Asked Questions (FAQ)

Q: Can 0349002102 be used as a direct replacement for 0349002002?

A: Yes. The 0349002102 maintains identical electrical and mechanical parameters including connector type, contact configuration, pitch, mounting method, and fastening type. The primary difference is product status (active vs. obsolete) and packaging format.

Q: What is the difference between the yellow (0349002102) and black (0349002120, 0349002121) variants?

A: The yellow variant (0349002102) matches the original color specification. The black variants (0349002120 and 0349002121) provide the same functional performance with an extended operating temperature range of -40°C to 155°C. Color selection should be based on application requirements and system design specifications.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts (0349002102, 0349002120, 0349002121) are ROHS3 compliant with MSL rating of 1 (unlimited moisture sensitivity level).

Q: What is the packaging difference between these parts?

A: The original 0349002002 is supplied in standard packaging. Substitute parts 0349002102, 0349002120, and 0349002121 are supplied in bulk packaging format.

Q: Can these housings be used interchangeably in the same assembly?

A: Yes, provided the application does not have specific color-coding requirements or thermal operating constraints. All parts share identical mechanical interfaces, contact configurations, and mounting characteristics within the MXP120 34900 series.
