Molex 0349006028 Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0349006028 is a 6-position rectangular connector housing designed for 0.157" (4.00mm) pitch applications. This receptacle housing accommodates female blade socket contacts and features a sealed design with crimp termination. The part is classified as obsolete, making identification of active equivalent alternatives essential for ongoing procurement and system maintenance. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct interchangeability without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0349006028 is determined by the following critical parameters:

• Connector Type & Contact Configuration: Must be receptacle with female blade socket contacts
• Position Count & Pitch: Exactly 6 positions at 0.157" (4.00mm) pitch
• Mechanical Interface: Single row, free hanging in-line mounting with latch holder fastening
• Termination Method: Crimp contact termination
• Environmental Sealing: Sealed housing design
• Compliance Standards: ROHS3 compliance and MSL 1 rating

The substitute part Molex 0349006128 satisfies all mandatory substitution criteria. Variations in housing color (black to gray) and insulation material composition do not affect electrical or mechanical interchangeability, as these are cosmetic and material property differences within the same connector family.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0349006128 is the direct substitute for the obsolete Molex 0349006028. Both parts share identical electrical and mechanical specifications within the MXP120 34900 series. The substitute part maintains ROHS3 compliance and MSL 1 rating, ensuring regulatory and environmental compatibility.

The primary distinction is product status: the original part is obsolete while the substitute remains in active production with significantly higher inventory availability (15,035 units versus 987 units). Housing color difference (gray versus black) represents a cosmetic variation that does not affect connector function, mating capability, or electrical performance.

For new designs or system refreshes, the Molex 0349006128 is the appropriate selection. For legacy system maintenance requiring the original black housing, compatibility must be evaluated based on specific application constraints, as the substitute's gray housing may present visual identification differences in existing assemblies.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0349006128 directly replace the 0349006028 in existing applications?

A: Yes. Both parts are electrically and mechanically identical within the MXP120 34900 series. They share the same 6-position, 4.00mm pitch configuration, contact type, mounting method, and sealing characteristics. The housing color difference does not affect interchangeability.

Q: What is the significance of the product status change from obsolete to active?

A: The obsolete status of the 0349006028 indicates Molex has discontinued production. The 0349006128 is the active equivalent, ensuring continued availability for procurement and supply chain continuity. Inventory levels reflect this status difference.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts maintain ROHS3 compliance and MSL 1 (Unlimited) rating. Regulatory and environmental certifications are identical.

Q: Does the housing color change affect mating or contact performance?

A: No. Housing color is a cosmetic attribute. Mating surfaces, contact geometry, pitch, and electrical properties remain unchanged. The sealed design and latch holder fastening function identically regardless of color.

Q: What is the base product number relationship?

A: Both parts share the base product number 034900, confirming they belong to the same connector family and design generation within the MXP120 series.

Q: Are contacts included with these housings?

A: No. Both the 0349006028 and 0349006128 are housings only. Female blade socket contacts must be procured separately and crimped into the housing.
