TE Connectivity 641534-8 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 641534-8 is an 8-position rectangular receptacle connector from the MTA-100 series, designed for IDC (Insulation Displacement Contact) termination with 22 AWG discrete or ribbon cable. This connector features tin-lead contact finish, a closed-end design, and a locking ramp fastening mechanism. The part is currently active in production with 894 pieces in stock.

Identifying equivalent and substitute parts is necessary when the primary part number becomes unavailable, when procurement requires alternative packaging configurations, or when compliance requirements necessitate RoHS-compliant alternatives.

Substitute Part Grouping Explanation

The substitute part 3-641534-8 is a direct functional equivalent of the 641534-8 within the MTA-100 rectangular connector series. Substitution eligibility is determined by the following critical parameters that must remain identical:

• Connector Type: Both parts are receptacles
• Number of Positions: Both are 8-position connectors
• Pitch: Both maintain 0.100" (2.54mm) spacing
• Number of Rows: Both are single-row configurations
• Contact Type: Both feature female socket contacts
• Cable Termination: Both use IDC termination
• Wire Gauge: Both accommodate 22 AWG wire
• Wire Type: Both accept discrete or ribbon cable
• Mounting Type: Both support free hanging (in-line) and right angle mounting
• Fastening Type: Both use locking ramp fastening
• Features: Both have closed-end design
• Contact Finish Thickness: Both specify 80.0µin (2.03µm)

The primary difference between these parts is the contact finish material (tin-lead versus tin) and the resulting RoHS compliance status. The substitute part 3-641534-8 is RoHS3 compliant, whereas the main part 641534-8 is RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

Both the 641534-8 and 3-641534-8 are active production parts from TE Connectivity AMP Connectors and are functionally equivalent for applications requiring 8-position, 0.100" pitch rectangular receptacle connectors with IDC termination for 22 AWG cable.

Selection based on compliance requirements:

The 3-641534-8 substitute part is the appropriate choice for applications subject to RoHS3 compliance mandates. This part maintains all functional and mechanical parameters of the original 641534-8 while eliminating lead from the contact finish material.

The 641534-8 original part remains suitable for applications where RoHS compliance is not a requirement and where tin-lead contact finish is specified or preferred.

Both parts share identical electrical and mechanical specifications, including connector geometry, contact configuration, termination method, and wire gauge compatibility. The MSL rating of 1 (Unlimited) for both parts indicates no moisture sensitivity restrictions during storage or handling.

Frequently Asked Questions (FAQ)

Q: Are the 641534-8 and 3-641534-8 mechanically interchangeable?

A: Yes. Both parts are 8-position receptacle connectors with identical pitch (0.100"), mounting type (free hanging in-line and right angle), and fastening mechanism (locking ramp). They accept the same cable types and wire gauges (22 AWG discrete or ribbon cable).

Q: What is the difference between these two part numbers?

A: The primary difference is the contact finish material. The 641534-8 uses tin-lead finish, while the 3-641534-8 uses tin finish. This difference results in different RoHS compliance statuses: the 641534-8 is RoHS non-compliant, and the 3-641534-8 is RoHS3 compliant. Both maintain the same contact finish thickness of 80.0µin (2.03µm).

Q: Can I use the 3-641534-8 as a direct replacement for the 641534-8?

A: Yes, the 3-641534-8 is a direct substitute for the 641534-8 in all applications where the connector specifications are met. The tin contact finish of the substitute part is compatible with the same mating components and cable termination processes as the tin-lead finish of the original part.

Q: What does IDC termination mean?

A: IDC (Insulation Displacement Contact) termination is a cable connection method where the connector contacts pierce through the insulation of the wire without requiring stripping or pre-tinning. This method is used with both discrete wires and ribbon cables.

Q: Are there any packaging differences between these parts?

A: The 641534-8 packaging is not specified in the available data. The 3-641534-8 is supplied in bulk packaging. Packaging configuration may affect procurement quantities and handling procedures but does not impact electrical or mechanical compatibility.

Q: What is the MSL rating, and why does it matter?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited moisture sensitivity, meaning these connectors have no moisture absorption restrictions and do not require special storage or handling conditions. Both parts share this MSL rating.

Q: Which part should I specify for new designs?

A: For new designs subject to RoHS compliance requirements, specify the 3-641534-8. For legacy systems or applications without RoHS mandates, either part is acceptable based on design requirements and procurement availability.
