Substitute Part Grouping Explanation

Substitution of the 4-644375-0 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Receptacle
• Contact Type: Female Socket
• Number of Positions: 10
• Pitch: 0.156" (3.96mm)
• Number of Rows: 1
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Locking Ramp
• Cable Termination: IDC
• Wire Gauge: 18 AWG
• Contact Finish: Tin
• Contact Finish Thickness: 80.0µin (2.03µm)
• Features: Feed Through
• Series: MTA-156

The substitute part 4-640599-0 maintains complete electrical and mechanical compatibility with the original part across all specified parameters. The primary distinction is product status: the original part is obsolete while the substitute is active, ensuring continued availability and supply chain support.

Parameter Comparison

Engineering Selection Recommendations

The 4-640599-0 serves as a direct functional equivalent to the 4-644375-0 for all electrical and mechanical applications. Selection of the substitute part is supported by the following engineering considerations:

Product Status: The original part 4-644375-0 is classified as obsolete, indicating discontinued manufacturing and limited availability. The substitute part 4-640599-0 maintains active product status with confirmed inventory of 2434 units, ensuring reliable supply for current and future production requirements.

Regulatory Compliance: Both parts maintain compliance with RoHS directives and carry identical ECCN classification (EAR99), confirming equivalent regulatory standing for export and domestic applications.

Electrical and Mechanical Compatibility: All critical parameters determining connector function, mating capability, and signal integrity are identical between the original and substitute parts. The 10-position, 0.156" pitch configuration with IDC termination for 18 AWG wire remains unchanged, ensuring direct interchangeability in existing designs.

Environmental Classification: Both parts carry MSL 1 (Unlimited) rating, indicating identical moisture sensitivity and storage requirements.

The only non-functional difference is connector color (black versus orange), which does not affect electrical performance or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 4-640599-0 be used as a direct replacement for the 4-644375-0 in existing designs?

A: Yes. The 4-640599-0 is electrically and mechanically identical to the 4-644375-0 across all functional parameters. Both connectors feature 10 positions, 0.156" pitch, IDC termination, tin contact finish, and feed-through capability. Direct substitution is supported without design modification.

Q: What is the significance of the color difference between the two parts?

A: The color difference (black for 4-644375-0 versus orange for 4-640599-0) is cosmetic and does not affect electrical performance, mechanical compatibility, or signal integrity. Color selection is typically driven by manufacturing batch or supplier preference and does not impact functional equivalence.

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

A: Both parts maintain RoHS compliance and carry identical ECCN classification (EAR99). The original part is ROHS3 compliant while the substitute is RoHS compliant, both meeting current regulatory requirements. Moisture sensitivity levels are identical at MSL 1 (Unlimited).

Q: Why is the original part 4-644375-0 classified as obsolete?

A: Obsolete classification indicates that the manufacturer has discontinued production of this part number. The substitute part 4-640599-0 remains in active production, ensuring continued availability and supply chain support for applications requiring this connector type.

Q: What wire gauges and termination methods are supported by the substitute part?

A: The 4-640599-0 supports 18 AWG wire with IDC (Insulation Displacement Contact) termination. It accommodates both discrete and ribbon cable configurations and features feed-through capability for signal pass-through applications.

Q: Are there inventory considerations when selecting between these parts?

A: The original part 4-644375-0 has limited inventory (697 units) due to obsolete status. The substitute part 4-640599-0 has significantly higher availability (2434 units) and active production status, making it the preferred choice for new designs and ongoing production requirements.

Q: What is the pitch specification and why is it important for substitution?

A: Both parts feature a 0.156" (3.96mm) pitch, which defines the center-to-center spacing between connector positions. Pitch is a critical parameter for mechanical compatibility; identical pitch ensures proper mating with corresponding plug connectors and PCB layouts.

Q: Can these connectors be used with ribbon cable applications?

A: Yes. Both the 4-644375-0 and 4-640599-0 support ribbon cable termination through IDC technology, in addition to discrete wire configurations. The feed-through feature enables signal continuity across the connector.
