TE Connectivity 640599-7 Rectangular Connector: Equivalent & Substitute Parts

Part Overview

The TE Connectivity 640599-7 is a 7-position rectangular receptacle connector from the MTA-156 series, designed for IDC (Insulation Displacement Contact) termination with 18 AWG discrete or ribbon cable. This connector features tin-lead contact finish, free-hanging in-line mounting, and locking ramp fastening. The part is currently active in production with 1,085 units in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across connector specifications. The primary substitute listed differs in contact finish material and RoHS compliance status while maintaining all critical functional parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 640599-7 is determined by the following critical parameters that must remain constant:

• Connector Type & Position Count: Receptacle configuration with 7 positions
• Pitch & Row Configuration: 0.156" (3.96mm) pitch, single row
• Contact Type & Gender: Female socket contacts
• Cable Termination: IDC method for 18 AWG wire
• Mounting & Fastening: Free-hanging in-line mounting with locking ramp fastening
• Series Classification: MTA-156 series designation

The substitute part 3-640599-7 maintains all these parameters. Variations in contact finish material (tin-lead versus tin) and RoHS compliance status do not affect mechanical or electrical compatibility within the MTA-156 series framework.

Parameter Comparison

Engineering Selection Recommendations

Both the 640599-7 and 3-640599-7 are active production parts from TE Connectivity with identical mechanical and electrical specifications within the MTA-156 series. Selection between these parts is determined by regulatory and compliance requirements:

640599-7 (Tin-Lead Contact Finish): Suitable for applications where RoHS compliance is not mandated. This part carries RoHS non-compliant status and REACH Affected designation.

3-640599-7 (Tin Contact Finish): Suitable for applications requiring ROHS3 compliance. This substitute maintains all functional parameters while meeting modern regulatory standards. The contact finish material change from tin-lead to tin does not alter electrical performance or mechanical compatibility within the MTA-156 connector system.

Both parts feature identical contact finish thickness (80.0µin / 2.03µm), moisture sensitivity level (MSL 1), and export classification (EAR99). Selection should be based on the specific regulatory environment and compliance requirements of the end application.

Frequently Asked Questions (FAQ)

Q: Can 3-640599-7 be used as a direct replacement for 640599-7?

A: Yes. The 3-640599-7 maintains all critical mechanical and electrical parameters: 7-position receptacle configuration, 0.156" pitch, IDC termination for 18 AWG cable, free-hanging in-line mounting, and locking ramp fastening. The contact finish material change from tin-lead to tin does not affect connector compatibility or performance within the MTA-156 series.

Q: What is the primary difference between these two parts?

A: The main differences are contact finish material (tin-lead versus tin) and RoHS compliance status. The 640599-7 uses tin-lead finish and is RoHS non-compliant, while the 3-640599-7 uses tin finish and is ROHS3 compliant. Both maintain identical contact finish thickness and all functional specifications.

Q: Are there packaging differences between 640599-7 and 3-640599-7?

A: Yes. The 640599-7 is supplied with unspecified packaging, while the 3-640599-7 is supplied in bulk packaging. This distinction affects inventory management and ordering quantities but does not impact connector functionality or compatibility.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring ROHS3 compliance, specify 3-640599-7. For applications without RoHS requirements, either part is functionally equivalent. Both parts are active in production with adequate inventory availability.

Q: Is the contact finish thickness the same for both parts?

A: Yes. Both 640599-7 and 3-640599-7 feature identical contact finish thickness of 80.0µin (2.03µm), ensuring consistent electrical contact resistance and durability characteristics.

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

A: Yes. Both parts support discrete or ribbon cable termination via IDC method at 18 AWG wire gauge. The feed-through feature accommodates both cable types within the specified wire gauge range.
