TE Connectivity AMP Connectors 644617-6 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 644617-6 is a rectangular connector header designed for through-hole, right-angle mounting applications. This connector features a 6-position configuration with 0.156" (3.96mm) pitch spacing, suitable for board-to-cable/wire connections in general purpose and industrial applications. The part operates across a temperature range of -55°C to 105°C with a 600VAC voltage rating.

The 644617-6 carries an obsolete product status, which necessitates identification of active equivalent alternatives to ensure continued component availability for new designs, repairs, and production continuity. Substitute parts must maintain electrical and mechanical compatibility while meeting current manufacturing and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 644617-6 is based on strict electrical and mechanical parameter matching within the MTA-156 connector series. The following parameters determine substitution eligibility:

Critical Matching Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (6)
• Pitch spacing (0.156" / 3.96mm)
• Mounting configuration (Through Hole, Right Angle)
• Shrouding style (Shrouded - 1 Wall)
• Contact dimensions (Mating length 0.450", Post length 0.125")
• Insulation height (0.300")
• Voltage rating (600VAC)
• Operating temperature range (-55°C ~ 105°C)
• Flammability rating (UL94 V-0)

The substitute part 3-644617-6 maintains identical mechanical and electrical specifications across all critical parameters. The primary distinction is product status (active versus obsolete) and contact finish composition (Tin versus Tin-Lead), with both finishes meeting the same thickness specification of 150.0µin (3.81µm).

Parameter Comparison

Engineering Selection Recommendations

The 3-644617-6 serves as the direct active equivalent to the obsolete 644617-6. Both parts maintain identical mechanical and electrical specifications across all critical connector parameters, ensuring functional interchangeability in board-to-cable/wire applications.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The 644617-6 is classified as obsolete with RoHS non-compliant status, while the 3-644617-6 is an active product with ROHS3 compliance. This compliance upgrade reflects current manufacturing standards and regulatory requirements for new designs and production environments.

Contact finish composition differs between the parts: the 644617-6 uses Tin-Lead plating, while the 3-644617-6 uses Tin plating. Both finishes maintain the same thickness specification of 150.0µin (3.81µm) and are applied to both mating and post contact surfaces. This finish transition aligns with the RoHS3 compliance requirement of the substitute part.

For applications requiring new component procurement, design updates, or production continuity, the 3-644617-6 is the appropriate selection. Both parts are manufactured by TE Connectivity AMP Connectors within the MTA-156 series and maintain full compatibility with existing connector systems designed for 0.156" (3.96mm) pitch, 6-position header configurations.

Frequently Asked Questions (FAQ)

Q: Can the 3-644617-6 be used as a direct replacement for the 644617-6 in existing designs?

A: Yes. The 3-644617-6 maintains identical mechanical and electrical specifications across all critical parameters including connector type, position count, pitch spacing, mounting configuration, contact dimensions, voltage rating, and operating temperature range. Both parts are manufactured by TE Connectivity AMP Connectors within the MTA-156 series and are functionally interchangeable.

Q: What is the difference between the Tin-Lead finish on the 644617-6 and the Tin finish on the 3-644617-6?

A: Both finishes meet the same thickness specification of 150.0µin (3.81µm) on mating and post contacts. The finish composition change reflects the RoHS3 compliance requirement of the 3-644617-6. The Tin finish on the substitute part provides equivalent electrical and mechanical performance for the specified applications.

Q: Why is the 644617-6 listed as obsolete?

A: The 644617-6 carries an obsolete product status, indicating it is no longer in active production. The 3-644617-6 is the active equivalent part that replaces it in the product line. For new designs and ongoing production, the 3-644617-6 should be specified.

Q: Are there any packaging differences between these parts?

A: The 644617-6 packaging specification is not provided in the available data. The 3-644617-6 is supplied in bulk packaging. Specific packaging requirements should be confirmed with the component supplier based on application needs.

Q: What is the significance of the RoHS3 compliance on the 3-644617-6?

A: ROHS3 compliance indicates the 3-644617-6 meets current regulatory requirements for restricted substances in electrical and electronic equipment. This compliance is required for many industrial and commercial applications, particularly in markets with strict environmental regulations. The obsolete 644617-6 does not carry this compliance designation.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the 644617-6 and 3-644617-6 operate across the identical temperature range of -55°C to 105°C, ensuring thermal compatibility in all specified applications.

Q: What connector systems are compatible with these 6-position headers?

A: Both parts are designed for board-to-cable/wire connections within the MTA-156 series using 0.156" (3.96mm) pitch spacing. They feature shrouded 1-wall design with friction lock fastening and are compatible with mating connectors designed for this pitch and configuration.

Q: Is the moisture sensitivity level the same for both parts?

A: Yes. Both the 644617-6 and 3-644617-6 carry a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without special moisture control requirements.
