Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 640442-2 is based on strict equivalence across the following critical parameters:

Mechanical Compatibility Parameters:

• Connector type (Receptacle)
• Number of positions (2)
• Pitch spacing (0.100" / 2.54mm)
• Number of rows (1)
• Mounting configuration (Free Hanging In-Line, Right Angle)
• Fastening mechanism (Locking Ramp)

Electrical & Termination Parameters:

• Cable termination method (IDC)
• Wire gauge compatibility (26 AWG)
• Contact type (Female Socket)
• Closed-end feature

Physical & Environmental Parameters:

• Color (Blue)
• Contact finish thickness (80.0µin / 2.03µm)
• Moisture Sensitivity Level (MSL 1 - Unlimited)

The substitute part 3-640442-2 maintains equivalence across all mechanical, electrical, and environmental parameters while differing only in contact finish composition (tin versus tin-lead) and regulatory compliance status.

Engineering Selection Recommendations

Primary Substitute: 3-640442-2

The part 3-640442-2 is the direct substitute for 640442-2 based on the following engineering criteria:

Mechanical & Electrical Equivalence: All mechanical dimensions, contact configurations, termination methods, and electrical parameters are identical. The connector maintains the same 2-position, 0.100" pitch receptacle configuration with IDC termination for 26 AWG cable.

Product Status Advantage: The substitute part carries active product status, ensuring continued availability and manufacturing support. The original 640442-2 is classified as obsolete, limiting future procurement options.

Regulatory Compliance: The substitute part 3-640442-2 is RoHS compliant, whereas the original part is RoHS non-compliant. This provides improved compliance for applications subject to RoHS regulations. Both parts maintain identical MSL ratings and ECCN classifications.

Contact Finish Consideration: The substitute uses tin contact finish instead of tin-lead. Both finishes maintain the same 80.0µin (2.03µm) thickness specification, ensuring equivalent electrical and mechanical performance in IDC applications.

Inventory & Availability: Both parts maintain substantial inventory levels (1061 units for 640442-2 and 1047 units for 3-640442-2), supporting immediate procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can 3-640442-2 be used as a direct replacement for 640442-2 in existing designs?

A: Yes. The substitute part maintains identical mechanical, electrical, and environmental specifications across all critical parameters including connector type, position count, pitch, mounting configuration, cable termination method, and wire gauge compatibility.

Q: What is the difference between the tin-lead finish on 640442-2 and the tin finish on 3-640442-2?

A: Both finishes maintain the same 80.0µin (2.03µm) thickness specification. The contact finish composition differs, but the electrical and mechanical performance in IDC applications remains equivalent. The tin finish on the substitute part supports improved RoHS compliance.

Q: Why is 640442-2 classified as obsolete?

A: Product obsolescence is determined by manufacturer lifecycle decisions. The substitute part 3-640442-2 maintains active status, ensuring continued manufacturing support and availability.

Q: Are there any compatibility issues when substituting 3-640442-2 for 640442-2?

A: No compatibility issues exist. Both connectors are from the same MTA-100 series, share identical pitch spacing (0.100"), mounting type (Free Hanging In-Line, Right Angle), fastening mechanism (Locking Ramp), and IDC termination method for 26 AWG cable.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance relates to material composition restrictions and regulatory adherence, not electrical performance. Both parts deliver equivalent electrical characteristics in IDC applications.

Q: What packaging differences exist between these parts?

A: The original part 640442-2 packaging is not specified in available data. The substitute part 3-640442-2 is supplied in bulk packaging, suitable for production and repair applications.

Q: Are both parts suitable for discrete and ribbon cable termination?

A: Yes. Both 640442-2 and 3-640442-2 support discrete or ribbon cable termination via IDC method at 26 AWG wire gauge.
