TE Connectivity 644564-2 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 644564-2 is a 2-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 an active product with unlimited moisture sensitivity rating. Substitute parts are identified to address specific compliance requirements, packaging preferences, or inventory availability while maintaining functional equivalence within the MTA-100 series.

Key Parameters

Substitute Part Grouping Explanation

Substitution between the main part 644564-2 and the identified equivalent 3-644564-2 is based on strict equivalence of the following critical parameters:

• Connector Configuration: Both are 2-position rectangular receptacles within the MTA-100 series
• Electrical Interface: Identical pitch (0.100"), contact type (female socket), and contact finish thickness (80.0µin)
• Termination Method: Both utilize IDC termination for 26 AWG discrete or ribbon cable
• Mechanical Compatibility: Matching mounting type (free hanging in-line, right angle) and fastening mechanism (locking ramp)
• Environmental Rating: Both rated MSL 1 (unlimited moisture sensitivity)

The primary distinction between these parts is the contact finish material and RoHS compliance status. The substitute part 3-644564-2 features tin contact finish and is RoHS compliant, whereas the main part 644564-2 uses tin-lead finish and is RoHS non-compliant. Both maintain identical contact finish thickness and all mechanical/electrical parameters.

Engineering Selection Recommendations

Selection Criteria Based on Compliance and Product Status:

Both parts are active products from TE Connectivity's MTA-100 series with identical mechanical and electrical specifications. The selection between 644564-2 and 3-644564-2 is determined by regulatory and compliance requirements:

• For RoHS-compliant applications: Select 3-644564-2, which meets RoHS compliance requirements while maintaining all functional equivalence to the main part.

• For legacy or non-regulated applications: The 644564-2 remains suitable where RoHS compliance is not mandated.

• For inventory and packaging considerations: The substitute part 3-644564-2 is available in bulk packaging with higher inventory levels (5768 pcs vs. 1114 pcs), supporting higher-volume procurement scenarios.

Both parts carry identical ECCN (EAR99) and HTSUS classifications, ensuring equivalent export and tariff treatment. The contact finish material difference (tin-lead vs. tin) does not alter the mechanical interface or electrical performance within the specified 26 AWG wire gauge and IDC termination parameters.

Frequently Asked Questions (FAQ)

Q: Are 644564-2 and 3-644564-2 mechanically interchangeable?

A: Yes. Both connectors share identical pitch (0.100"), mounting configuration (free hanging in-line, right angle), fastening mechanism (locking ramp), and contact geometry. They are mechanically interchangeable within MTA-100 series applications.

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

A: Both contact finishes are applied at identical thickness (80.0µin). The primary distinction is regulatory: tin-lead finish is associated with RoHS non-compliance, while tin finish meets RoHS requirements. Functionally, both provide equivalent contact resistance and durability for IDC termination with 26 AWG cable.

Q: Can I use 3-644564-2 as a direct replacement for 644564-2 in existing designs?

A: Yes, provided your application does not have specific requirements for tin-lead contact finish. The substitute part maintains all electrical and mechanical parameters. Verify RoHS compliance requirements for your end application.

Q: What does the packaging difference (standard vs. bulk) mean for component selection?

A: Packaging designation indicates order quantity increments and storage format. Bulk packaging typically supports higher-volume orders. Both parts are identical in form, fit, and function; packaging choice depends on procurement volume and inventory management requirements.

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

A: Yes. Both 644564-2 and 3-644564-2 support IDC termination for discrete or ribbon cable at 26 AWG wire gauge. The IDC mechanism and contact design are identical across both parts.

Q: What is the significance of MSL 1 (Unlimited) rating for these connectors?

A: MSL 1 indicates the connector has unlimited shelf life and requires no special moisture control during storage or handling. This applies equally to both the main part and substitute, simplifying inventory management and logistics.
