TE Connectivity 640441-9 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 640441-9 is a 9-position rectangular receptacle connector from the MTA-100 series, designed for IDC (Insulation Displacement Contact) termination with 24 AWG discrete or ribbon cable. This connector features tin-lead contact finish and is classified as a closed-end receptacle with free-hanging or right-angle mounting capability using a locking ramp fastening mechanism.

The 640441-9 is an active product with 810 units currently in stock. Equivalent substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when specific compliance requirements necessitate component substitution.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 640441-9 are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following key parameters that must remain constant:

• Connector Type & Series: Rectangular receptacle from MTA-100 series
• Position Count & Pitch: 9 positions at 0.100" (2.54mm) spacing
• Contact Configuration: Female socket, single row
• Termination Method: IDC with 24 AWG wire compatibility
• Mounting & Fastening: Free-hanging or right-angle with locking ramp
• Physical Features: Closed-end design, white color
• Environmental Rating: MSL 1 (Unlimited)

The identified substitute part maintains all electrical and mechanical parameters while differing in contact finish specification and RoHS compliance status. This substitution is valid for applications where the contact finish material and regulatory compliance requirements are compatible with the application environment.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (640441-9): Select this part number when the application does not require RoHS compliance or when legacy systems specifically require tin-lead contact finish. The part is active and maintains full inventory availability.

Substitute Part (3-640441-9): Select this part number when RoHS compliance is required by design specifications, regulatory requirements, or customer mandates. The substitute part is RoHS compliant and maintains identical electrical and mechanical specifications. The substitute part offers significantly higher inventory availability (23,410 units) compared to the primary part.

Contact Finish Consideration: The primary difference between these parts is the contact finish material. The 640441-9 uses tin-lead finish, while the 3-640441-9 uses tin finish. Both finishes maintain the same thickness specification of 80.0µin (2.03µm). Selection between these parts should be based on regulatory compliance requirements and application environmental conditions.

Both parts are active products from TE Connectivity AMP Connectors and share identical mechanical, electrical, and environmental specifications within the MTA-100 series.

Frequently Asked Questions (FAQ)

Q: Are the 640441-9 and 3-640441-9 mechanically interchangeable?

A: Yes. Both connectors are 9-position rectangular receptacles with identical pitch (0.100"), mounting type (free-hanging or right-angle), fastening mechanism (locking ramp), and cable termination method (IDC 24 AWG). They are mechanically and electrically interchangeable in applications where contact finish material is not a constraint.

Q: What is the primary difference between these two part numbers?

A: The primary difference is the contact finish material. The 640441-9 features tin-lead contact finish, while the 3-640441-9 features tin contact finish. Both maintain identical finish thickness of 80.0µin (2.03µm). The 3-640441-9 is RoHS compliant, while the 640441-9 is RoHS non-compliant.

Q: Which part should be selected for new designs?

A: For new designs, the 3-640441-9 is recommended due to RoHS compliance status and higher inventory availability. The tin contact finish meets modern environmental and regulatory standards while maintaining full compatibility with the MTA-100 series specifications.

Q: Can these connectors be used with both discrete and ribbon cable?

A: Yes. Both the 640441-9 and 3-640441-9 support IDC termination with discrete or ribbon cable at 24 AWG wire gauge.

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

A: Both connectors have a Moisture Sensitivity Level (MSL) of 1, which indicates unlimited shelf life without moisture control requirements.

Q: Are there any packaging differences between these part numbers?

A: The 640441-9 is supplied in standard packaging, while the 3-640441-9 is supplied in bulk packaging. Both are new original stock from TE Connectivity.

Q: What is the locking ramp fastening mechanism?

A: The locking ramp is the fastening mechanism used to secure the connector in place. It provides mechanical retention for the 9-position receptacle connector in the MTA-100 series.
