TE Connectivity 644564-4 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 644564-4 is a 4-position rectangular receptacle connector from the MTA-100 series, designed for IDC (Insulation Displacement Contact) termination with 26 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 1,099 units in stock.

Substitute parts are identified when equivalent connectors maintain identical electrical and mechanical specifications while offering alternative packaging, compliance status, or contact finish materials. Identifying suitable alternatives ensures design flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 644564-4 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Number of positions: 4
• Pitch: 0.100" (2.54mm)
• Wire gauge: 26 AWG
• Contact type: Female socket
• Cable termination: IDC

Mechanical Compatibility Parameters:

• Connector type: Receptacle
• Mounting type: Free Hanging (In-Line), Right Angle
• Fastening type: Locking ramp
• Number of rows: 1
• Contact finish thickness: 80.0µin (2.03µm)

Environmental Parameters:

• Moisture sensitivity level: 1 (Unlimited)
• Series: MTA-100

The substitute part 3-644564-4 maintains all electrical and mechanical specifications identical to the main part. The primary differences are packaging format (bulk versus standard) and contact finish material (tin versus tin-lead), with corresponding RoHS compliance status variation.

Parameter Comparison

Engineering Selection Recommendations

644564-4 Selection Criteria: The 644564-4 is appropriate for applications where tin-lead contact finish is specified or required by design documentation. This part is RoHS non-compliant and suitable for legacy systems or applications without RoHS restrictions. Standard packaging is available with 1,099 units in current inventory.

3-644564-4 Selection Criteria: The 3-644564-4 is the preferred alternative for new designs and applications subject to RoHS compliance requirements. This substitute maintains identical electrical and mechanical performance while offering tin contact finish and RoHS compliance. Bulk packaging format and higher inventory availability (2,629 units) support high-volume production requirements.

Both parts are active products from TE Connectivity with identical MTA-100 series specifications, ensuring long-term availability and design stability. Selection between these parts is determined by compliance requirements and packaging needs rather than functional performance differences.

Frequently Asked Questions (FAQ)

Q: Are 644564-4 and 3-644564-4 electrically interchangeable?

A: Yes. Both connectors maintain identical electrical specifications including 4-position configuration, 0.100" pitch, 26 AWG wire gauge, IDC termination, and female socket contact type. Electrical performance is equivalent.

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

A: The 644564-4 features tin-lead contact finish while the 3-644564-4 features tin contact finish. Both maintain the same 80.0µin (2.03µm) finish thickness. The contact finish material difference reflects the RoHS compliance status of each part.

Q: Can I use 3-644564-4 as a direct replacement for 644564-4 in existing designs?

A: Mechanical and electrical compatibility is confirmed. The 3-644564-4 is a direct substitute from a functional standpoint. Design review is required only if tin-lead contact finish is explicitly specified in original design documentation.

Q: What does RoHS compliance mean for connector selection?

A: RoHS compliance restricts the use of certain hazardous substances in electrical and electronic equipment. The 3-644564-4 is RoHS compliant; the 644564-4 is not. Selection depends on regulatory requirements applicable to the end application and market region.

Q: Does packaging format affect connector performance?

A: No. Standard and bulk packaging formats contain identical connectors. Packaging selection is based on order quantity, inventory management, and supply chain requirements rather than electrical or mechanical performance.

Q: Are both parts available for immediate shipment?

A: Both parts are active products in current inventory. The 644564-4 has 1,099 units available; the 3-644564-4 has 2,629 units available. Inventory status should be confirmed at time of order.

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

A: Yes. Both the 644564-4 and 3-644564-4 support discrete or ribbon cable termination via IDC method at 26 AWG wire gauge.
