Molex 0428910097 Equivalent & Substitute Parts

Part Overview

The Molex 0428910097 is an active rectangular connector header designed for through-hole mounting applications. This vertical 3-position connector 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 1066 pieces in current inventory, this component serves general purpose, automotive, industrial, medical, and telecommunications applications. Equivalent parts may be required due to supply constraints, design revisions, or application-specific performance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0428910097 is determined by strict alignment of the following parameters:

• Pitch - Mating: 0.156" (3.96mm)
• Number of Positions: 3
• Number of Rows: 1
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Shrouding: Shrouded - 1 Wall
• Fastening Type: Friction Lock
• Contact Shape: Square
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

The substitute parts identified (TE Connectivity 3-644611-3 and 3-644615-3) meet all critical electrical and mechanical parameters. Both are active products with equivalent mating pitch, position count, shrouding configuration, and fastening mechanism. Variations in contact material (copper alloy vs. brass), insulation material composition (thermoplastic vs. polyester), contact finish thickness, and operating temperature range do not preclude functional substitution within the specified parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

Both TE Connectivity substitute parts maintain active product status and full ROHS3 compliance, meeting regulatory requirements equivalent to the Molex 0428910097. The TE Connectivity 3-644611-3 and 3-644615-3 are functionally interchangeable based on matching electrical and mechanical specifications across all critical parameters.

The TE Connectivity 3-644615-3 includes a board guide feature not present in the Molex original, providing additional mechanical stability during mating operations. The TE Connectivity 3-644611-3 offers standard configuration without this feature.

Both substitute parts feature copper alloy contact material and thermoplastic insulation composition, differing from the Molex brass and polyester construction. These material variations do not affect compliance with UL94 V-0 flammability rating or functional performance within the specified parameter envelope.

The TE Connectivity MTA-156 series parts provide documented operating temperature range (-55°C ~ 105°C) and voltage rating (600VAC) not specified for the Molex original, offering extended environmental performance data for applications requiring temperature or voltage verification.

Frequently Asked Questions (FAQ)

Q: Are the TE Connectivity 3-644611-3 and 3-644615-3 fully interchangeable with the Molex 0428910097?

A: Both TE Connectivity parts meet all critical electrical and mechanical parameters: 0.156" (3.96mm) pitch, 3-position single-row configuration, through-hole solder termination, shrouded 1-wall design, and friction lock fastening. Functional interchangeability is established based on these matching specifications.

Q: What is the difference between TE Connectivity 3-644611-3 and 3-644615-3?

A: The primary difference is the inclusion of a board guide feature in the 3-644615-3 model. Both parts share identical electrical and mechanical specifications, pitch, position count, and termination method. The board guide provides additional mechanical alignment during connector mating.

Q: Do the substitute parts have different contact material specifications?

A: Yes. The Molex 0428910097 uses brass contacts, while both TE Connectivity substitutes use copper alloy contacts. Both materials are tin-plated and maintain equivalent electrical performance and UL94 V-0 flammability compliance.

Q: Are operating temperature and voltage ratings specified for the Molex original?

A: Operating temperature and voltage rating are not specified in the Molex 0428910097 documentation. The TE Connectivity substitutes provide documented ratings of -55°C ~ 105°C operating temperature and 600VAC voltage rating.

Q: Do all three parts meet RoHS compliance requirements?

A: Yes. The Molex 0428910097 and both TE Connectivity substitutes are ROHS3 compliant. The TE Connectivity 3-644615-3 has vendor-undefined REACH status, while the Molex original and 3-644611-3 are REACH unaffected.

Q: What is the difference in insulation material between the parts?

A: The Molex 0428910097 uses polyester glass-filled insulation, while both TE Connectivity substitutes use thermoplastic glass-filled insulation. Both materials achieve UL94 V-0 flammability rating and maintain equivalent performance within the specified parameter constraints.

Q: Can these connectors be used interchangeably in existing PCB designs?

A: Interchangeability depends on PCB footprint compatibility. All three parts share identical pitch (0.156"), position count (3), and through-hole mounting configuration. Physical dimensions including contact length and insulation height should be verified against PCB design specifications.
