TE Connectivity 640623-3 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 640623-3 is a 3-position rectangular receptacle connector from the MTA-100 series, designed for IDC (Insulation Displacement Contact) termination with 28 AWG discrete or ribbon cable. This connector features tin-lead contact finish and is classified as a feed-through receptacle with right-angle and free-hanging mounting options. The part is currently active in production with 976 pieces available in new original inventory.

Substitute parts are identified to address specific application requirements, including RoHS compliance status, contact finish specifications, and packaging configurations. Alternative part numbers within the same series maintain electrical and mechanical compatibility while offering different material certifications and availability options.

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 640623-3 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type: Receptacle
• Number of positions: 3
• Pitch: 0.100" (2.54mm)
• Number of rows: 1
• Contact type: Female socket
• Cable termination method: IDC
• Wire gauge: 28 AWG
• Wire type: Discrete or ribbon cable
• Mounting type: Free hanging (in-line) and right angle
• Fastening type: Locking ramp
• Contact finish thickness: 80.0µin (2.03µm)
• Series: MTA-100
• Moisture sensitivity level: 1 (unlimited)

Variable Parameters Allowing Substitution:

• Contact finish material (tin-lead versus tin)
• RoHS compliance status
• Packaging configuration (bulk versus standard)
• Inventory availability

The substitute part 3-640623-3 maintains complete electrical and mechanical compatibility with the main part while offering RoHS compliance and alternative packaging. Both parts share the same base product number (640623) and series designation, confirming their interchangeability within the MTA-100 connector family.

Parameter Comparison

Engineering Selection Recommendations

640623-3 Selection Criteria: The TE Connectivity 640623-3 is appropriate for applications where tin-lead contact finish is specified or required. This part maintains active production status and is suitable for legacy designs or systems with established tin-lead specifications. The part is RoHS non-compliant and should be selected only when regulatory exemptions apply or when tin-lead contact properties are functionally necessary.

3-640623-3 Selection Criteria: The substitute part 3-640623-3 is the preferred selection for new designs and applications subject to RoHS compliance requirements. This part offers identical electrical and mechanical performance with tin contact finish and is available in bulk packaging. The higher inventory level (3499 pieces) provides improved supply chain availability. Both parts are active products from TE Connectivity, ensuring long-term support and consistent manufacturing standards.

Compliance Considerations: Selection between these parts is primarily determined by RoHS compliance mandates. The 3-640623-3 substitute satisfies RoHS requirements while maintaining complete functional equivalence. Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.8000) classifications, indicating no regulatory differentiation in export or tariff treatment.

Frequently Asked Questions (FAQ)

Q: Are the 640623-3 and 3-640623-3 electrically interchangeable?

A: Yes. Both parts are 3-position receptacle connectors with identical pitch (0.100"), contact type (female socket), wire gauge (28 AWG), and IDC termination method. They operate identically in circuit applications and are mechanically compatible with the same mating connectors.

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

A: Contact finish material affects corrosion resistance and solderability characteristics. Tin-lead (640623-3) and tin (3-640623-3) finishes both provide reliable electrical contact at 80.0µin thickness. The primary distinction is RoHS compliance status, not electrical performance.

Q: Can I substitute 3-640623-3 for 640623-3 in existing designs?

A: Yes, provided the design does not explicitly require tin-lead contact finish. The substitute part maintains all electrical and mechanical specifications. Verify that RoHS compliance does not conflict with design requirements or regulatory exemptions.

Q: Why does 3-640623-3 have higher inventory availability?

A: The 3-640623-3 is packaged in bulk configuration and carries RoHS compliance, making it the standard production offering for new applications. The 640623-3 represents legacy inventory for non-compliant applications.

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

A: Yes. Both parts support IDC termination for discrete or ribbon cable at 28 AWG. The locking ramp fastening type and feed-through design accommodate both termination methods identically.

Q: What is the significance of the base product number 640623?

A: The base product number 640623 identifies the core connector design within the MTA-100 series. The suffix (3 or 3-640623-3) indicates packaging and compliance variants of the same fundamental product.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
