Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0535200320 is determined by strict equivalence across the following critical parameters:

• Pitch spacing: 0.156" (3.96mm) — determines mechanical compatibility with mating connectors and PCB layouts
• Number of positions and rows: 3 positions, 1 row — defines the connector footprint and contact count
• Connector type and contact type: Header with male pins — establishes the mating interface
• Mounting method: Through hole with solder termination — ensures PCB assembly compatibility
• Shrouding configuration: Shrouded with 1 wall and friction lock fastening — provides mechanical retention and polarization
• Contact shape: Square — maintains consistent contact geometry
• Flammability rating: UL94 V-0 — meets material safety requirements

The TE Connectivity AMP Connectors part number 640445-3 satisfies all these critical parameters, establishing it as a direct functional equivalent despite differences in contact length dimensions and insulation material composition.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 640445-3 is the active equivalent for the obsolete Molex 0535200320. Both connectors meet UL94 V-0 flammability requirements and maintain RoHS compliance. The TE Connectivity part offers the advantage of active product status with documented availability (2649 units in stock versus 637 for the Molex part).

Dimensional variations exist in contact length and insulation height between the two parts. The TE Connectivity 640445-3 features longer mating contact length (0.400" versus 0.303") and greater overall insulation height (0.425" versus 0.370"). These differences reflect design evolution within the MTA-156 series and do not affect functional compatibility for standard board-to-cable applications where mating depth is not constrained.

The TE Connectivity part specifies operating temperature range (-55°C to 105°C) and voltage rating (600VAC), parameters not documented for the Molex original. Selection should confirm these specifications align with application requirements.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 640445-3 directly replace the Molex 0535200320 in existing designs?

A: Yes, for applications where the connector footprint and pitch spacing are the primary design constraints. Both parts share identical pitch (0.156"), position count (3), mounting method (through hole), and fastening mechanism (friction lock). Dimensional differences in contact length and insulation height are within typical tolerance ranges for board-to-cable connector applications.

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

A: The primary differences are contact length dimensions, insulation material composition, and documented electrical specifications. The TE Connectivity part provides longer mating contact length and specifies operating temperature and voltage ratings. These variations reflect manufacturing evolution and do not affect mechanical compatibility for standard applications.

Q: Are both connectors RoHS compliant?

A: Yes. The Molex 0535200320 is ROHS3 compliant, and the TE Connectivity 640445-3 is RoHS compliant. Both meet current environmental compliance requirements.

Q: What is the moisture sensitivity level for these connectors?

A: Both connectors carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are there packaging differences between the original and substitute?

A: The Molex part packaging is not specified in available documentation. The TE Connectivity 640445-3 is supplied in bulk packaging. Confirm packaging requirements with your procurement process.

Q: What contact materials are used in each connector?

A: The Molex 0535200320 uses phosphor bronze contacts, while the TE Connectivity 640445-3 uses copper alloy contacts. Both are tin-finished for soldering compatibility.
