Molex 0428910098 Equivalent & Substitute Parts

Part Overview

The Molex 0428910098 is an active rectangular connector header designed for through-hole mounting applications. This 4-position vertical header operates at 0.156" (3.96mm) pitch and features shrouded design with friction lock fastening. The connector is manufactured from brass with tin plating and polyester glass-filled insulation rated UL94 V-0. With 853 units in current inventory, this component serves general purpose, automotive, industrial, medical, and telecommunications applications. Substitute parts may be required due to inventory constraints, lead time considerations, or specific application requirements within the allowed electrical and mechanical parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0428910098 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Pitch - Mating: 0.156" (3.96mm)
• Number of Positions: 4
• Number of Rows: 1
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Shrouding: Shrouded - 1 Wall
• Fastening Type: Friction Lock
• Contact Shape: Square
• Contact Finish - Mating: Tin
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

The TE Connectivity AMP Connectors part number 3-644615-4 (MTA-156 series) meets all mandatory matching parameters and qualifies as a direct substitute. Both connectors maintain identical mating pitch, position count, shrouding configuration, and fastening mechanism. Both are active products with ROHS3 compliance and UL94 V-0 flammability rating.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0428910098 and TE Connectivity 3-644615-4 are active products with ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on:

Molex 0428910098 is appropriate when the original design specification calls for brass contact material with polyester insulation, or when the specific contact post length of 0.140" (4.66mm) and insulation height of 0.446" (11.33mm) are required by PCB layout constraints.

TE Connectivity 3-644615-4 is appropriate as a substitute when inventory availability is a consideration, as 1823 units are in stock compared to 853 units for the Molex part. The TE part provides specified operating temperature range (-55°C ~ 105°C) and voltage rating (600VAC), which may be advantageous for applications requiring documented thermal and electrical performance. The copper alloy contact material and thermoplastic insulation are functionally equivalent for the stated application categories.

Both connectors maintain identical mating pitch, position count, and shrouding configuration, ensuring mechanical and electrical compatibility at the mating interface.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity 3-644615-4 be used as a direct replacement for Molex 0428910098?

A: Yes. Both connectors share identical mating pitch (0.156"), position count (4), row configuration (1), shrouding type (shrouded 1 wall), and fastening mechanism (friction lock). Both are active products with ROHS3 compliance and UL94 V-0 rating. Dimensional variations exist in contact post length and insulation height; verify PCB layout compatibility before substitution.

Q: What are the key differences between these two connectors?

A: Contact material differs (brass vs. copper alloy) and insulation material differs (polyester vs. thermoplastic). Contact post length is 0.140" for Molex versus 0.125" for TE Connectivity. Insulation height is 0.446" for Molex versus 0.545" for TE Connectivity. The TE part provides specified operating temperature (-55°C ~ 105°C) and voltage rating (600VAC), while the Molex part does not specify these parameters.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant and carry UL94 V-0 flammability rating. Both are active products with unlimited moisture sensitivity level (MSL 1). No compliance or certification differences exist between the two connectors.

Q: What should be verified before substituting these parts?

A: Verify that PCB through-hole spacing and solder pad layout accommodate the dimensional variations in contact post length (0.140" vs. 0.125") and insulation height (0.446" vs. 0.545"). Confirm that the mating connector interface is compatible with both header designs. Validate that the copper alloy and thermoplastic materials are acceptable for the intended application environment.

Q: Which part should be selected for new designs?

A: Selection depends on design requirements and material specifications. If the design specifies brass contacts and polyester insulation, use Molex 0428910098. If operating temperature range and voltage rating documentation are required, TE Connectivity 3-644615-4 provides these specifications. Both are suitable for general purpose, industrial, automotive, medical, and telecommunications applications.
