TE Connectivity 640440-5 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 640440-5 is a 5-position rectangular receptacle connector from the MTA-100 series, designed for IDC (Insulation Displacement Contact) termination with 22 AWG discrete or ribbon cable. This connector features tin-lead contact finish, a closed-end design, and free-hanging or right-angle mounting configuration with locking ramp fastening.

The 640440-5 is classified as obsolete. Locating equivalent or substitute components is necessary to support legacy system maintenance, repair, and continued field deployment where this connector type remains in use.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 640440-5 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility:

• Identical connector type (rectangular receptacle)
• Identical number of positions (5)
• Identical pitch (0.100" / 2.54mm)
• Identical row configuration (1 row)
• Identical contact type (female socket)
• Identical mounting type (free hanging in-line, right angle)
• Identical fastening mechanism (locking ramp)

Electrical & Termination Compatibility:

• Identical cable termination method (IDC)
• Identical wire gauge (22 AWG)
• Identical wire type support (discrete or ribbon cable)
• Identical contact finish thickness (80.0µin / 2.03µm)

Physical Characteristics:

• Identical closed-end design
• Identical color (red)
• Identical series designation (MTA-100)

The substitute part 3-640440-5 meets all mechanical, electrical, and physical requirements for direct substitution. The primary difference is the contact finish material (tin versus tin-lead) and product status (active versus obsolete).

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 3-640440-5

The 3-640440-5 is the direct equivalent substitute for the obsolete 640440-5. Both connectors share identical mechanical, electrical, and dimensional specifications within the MTA-100 series. The substitute part is currently in active production status with 3400 units in stock, ensuring availability for replacement and new assembly applications.

Compliance Considerations:

The 640440-5 is RoHS non-compliant with tin-lead contact finish. The substitute part 3-640440-5 is ROHS3 compliant with tin contact finish. For applications subject to RoHS regulations or environmental compliance requirements, the 3-640440-5 provides regulatory alignment while maintaining full functional and mechanical compatibility.

Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.8000) classifications, indicating equivalent export control and tariff treatment.

Moisture Sensitivity:

Both the main part and substitute are classified as MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage, handling, or assembly.

Frequently Asked Questions (FAQ)

Q: Can the 3-640440-5 be used as a direct replacement for the 640440-5?

A: Yes. The 3-640440-5 is mechanically and electrically equivalent to the 640440-5. Both connectors feature identical 5-position, 0.100" pitch rectangular receptacle design, IDC termination for 22 AWG cable, and locking ramp fastening. The substitute part is currently in active production.

Q: What is the difference between the tin-lead finish on the 640440-5 and the tin finish on the 3-640440-5?

A: The 640440-5 uses tin-lead contact finish, while the 3-640440-5 uses tin contact finish. Both maintain the same contact finish thickness of 80.0µin (2.03µm). The tin finish on the substitute part aligns with ROHS3 compliance requirements.

Q: Are there any mechanical compatibility issues when substituting the 3-640440-5 for the 640440-5?
