TE Connectivity 1-640441-9 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-640441-9 is a 19-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 part is currently active in production with 1,007 units in stock. Identification of equivalent substitute parts is necessary to support procurement flexibility, manage supply chain continuity, and accommodate specific compliance or packaging requirements in manufacturing environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1-640441-9 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type (Receptacle)
• Number of positions (19)
• Pitch specification (0.100" / 2.54mm)
• Number of rows (1)
• Contact type (Female Socket)
• Cable termination method (IDC)
• Wire gauge (24 AWG)
• Wire type compatibility (Discrete or Ribbon Cable)
• Mounting type (Free Hanging / Right Angle)
• Fastening type (Locking Ramp)
• Closed-end feature
• Contact finish thickness (80.0µin / 2.03µm)
• Series designation (MTA-100)
• Moisture sensitivity level (1)

Variable Parameters Permitting Substitution:

• Contact finish material (Tin-Lead vs. Tin)
• Packaging configuration (standard vs. bulk)
• RoHS compliance status

The substitute part 4-640441-9 maintains complete equivalence across all mandatory parameters while differing only in contact finish composition and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

1-640441-9 Selection Criteria: The 1-640441-9 is appropriate for applications where tin-lead contact finish is specified or required. This part is RoHS non-compliant and suitable for legacy systems, military applications, or environments where lead-based finishes are explicitly permitted or mandated. Standard packaging is available with robust inventory levels.

4-640441-9 Selection Criteria: The 4-640441-9 is the preferred substitute for new designs and applications subject to RoHS compliance requirements. The tin contact finish provides equivalent electrical and mechanical performance while meeting modern regulatory standards. Bulk packaging accommodates high-volume manufacturing operations. This part maintains full functional and dimensional compatibility with the 1-640441-9.

Compliance Considerations: Selection between these parts is primarily driven by RoHS compliance mandates. Both parts are active products from TE Connectivity with identical mechanical and electrical specifications. The contact finish material difference (tin-lead vs. tin) does not affect connector performance within the specified 24 AWG wire gauge and IDC termination parameters.

Frequently Asked Questions (FAQ)

Q: Are the 1-640441-9 and 4-640441-9 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including pitch (0.100"), position count (19), mounting type (free hanging/right angle), and fastening mechanism (locking ramp). They are direct mechanical substitutes.

Q: What is the functional difference between tin-lead and tin contact finishes?

A: Both finishes provide equivalent electrical conductivity and contact resistance performance at 24 AWG wire gauge. The primary difference is regulatory compliance: tin-lead is RoHS non-compliant, while tin is RoHS compliant. Contact finish thickness is identical at 80.0µin (2.03µm) for both variants.

Q: Can I use the 4-640441-9 in place of the 1-640441-9 in existing designs?

A: Yes, provided your application does not explicitly require tin-lead contact finish. The 4-640441-9 is a direct functional substitute with superior compliance status. Verify that your design documentation does not specify tin-lead as a mandatory requirement.

Q: What is the difference between standard and bulk packaging?

A: The 1-640441-9 uses standard packaging, while the 4-640441-9 is supplied in bulk packaging. Both packaging types contain the same connector specification. Bulk packaging is typically used for high-volume manufacturing operations to reduce per-unit packaging costs.

Q: Are both parts suitable for IDC termination with ribbon cable?

A: Yes. Both the 1-640441-9 and 4-640441-9 support IDC termination with discrete or ribbon cable at 24 AWG wire gauge. The closed-end feature and locking ramp fastening mechanism are identical across both parts.

Q: What is the moisture sensitivity level, and does it differ between these parts?

A: Both parts have a Moisture Sensitivity Level (MSL) of 1, which indicates unlimited shelf life without moisture control requirements. No special storage or handling precautions are necessary for either connector.

Q: Which part should I specify for new product designs?

A: Specify the 4-640441-9 for new designs unless tin-lead contact finish is explicitly required by application specifications or legacy system compatibility. The 4-640441-9 provides RoHS compliance and equivalent performance.
