Substitute Part Grouping Explanation

Substitution of the TE Connectivity 641536-2 is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following categories:

Electrical Parameters:

• Connector type (Rectangular Receptacle)
• Number of positions (2)
• Contact type (Female Socket)
• Wire gauge compatibility (26 AWG)
• Contact finish thickness (80.0µin / 2.03µm)

Mechanical Parameters:

• Pitch spacing (0.100" / 2.54mm)
• Mounting configuration (Free Hanging, In-Line, Right Angle)
• Fastening mechanism (Locking Ramp)
• Number of rows (1)
• Closed end feature

Termination Parameters:

• Cable termination method (IDC)
• Wire type compatibility (Discrete or Ribbon Cable)
• Series designation (MTA-100)

The substitute part 3-641536-2 meets all these criteria while offering improved product status and regulatory compliance.

Engineering Selection Recommendations

The substitute part 3-641536-2 is the direct equivalent for the obsolete 641536-2. Selection of the substitute part is based on the following engineering factors:

Product Status: The main part 641536-2 carries obsolete status, indicating discontinued manufacturing and limited availability. The substitute 3-641536-2 maintains active product status, ensuring reliable procurement and supply chain continuity.

Regulatory Compliance: The substitute part is RoHS compliant, whereas the main part is RoHS non-compliant. For applications subject to RoHS directives or customer requirements mandating RoHS compliance, the substitute part satisfies these regulatory obligations.

Contact Finish: The main part features tin-lead contact finish, while the substitute uses tin-only finish. Both maintain identical contact finish thickness (80.0µin / 2.03µm), ensuring equivalent electrical performance and contact reliability.

Functional Equivalence: All electrical and mechanical parameters remain identical between the main part and substitute. The connector maintains the same 2-position configuration, 0.100" pitch spacing, IDC termination method, 26 AWG wire gauge compatibility, and MTA-100 series designation.

Inventory Availability: The substitute part 3-641536-2 is available in significantly higher quantities (8270 pieces) compared to the main part (1000 pieces), supporting both immediate and future procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can the 3-641536-2 substitute directly replace the 641536-2 in existing designs?

A: Yes. The 3-641536-2 maintains identical electrical and mechanical specifications across all critical parameters including connector type, position count, pitch spacing, contact type, wire gauge, termination method, and mounting configuration. Direct substitution is supported without design modification.

Q: What is the difference between tin-lead and tin contact finishes in this application?

A: Both finishes provide equivalent electrical performance and contact reliability at the specified 80.0µin (2.03µm) thickness. The tin-only finish in the substitute part eliminates lead content, supporting RoHS compliance requirements. The contact finish thickness remains identical, maintaining equivalent contact resistance and durability characteristics.

Q: Why is the main part 641536-2 classified as obsolete?

A: Obsolete classification indicates the part has been discontinued by the manufacturer. The substitute part 3-641536-2 represents the current active equivalent, ensuring continued availability and manufacturing support.

Q: Are there any compatibility issues with ribbon cable or discrete wire termination?

A: No. Both the main part and substitute support identical wire types: discrete or ribbon cable at 26 AWG. The IDC termination method and locking ramp fastening mechanism function identically for both wire configurations.

Q: Does the substitute part meet RoHS requirements?

A: Yes. The 3-641536-2 is RoHS compliant. The main part 641536-2 is RoHS non-compliant due to its tin-lead contact finish. For applications requiring RoHS compliance, the substitute part satisfies these regulatory requirements.

Q: What is the moisture sensitivity level for both parts?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These connectors do not require special moisture control during storage, handling, or assembly.

Q: Are the base product numbers the same?

A: Yes. Both parts share the base product number 641536, confirming they are variants within the same product family. The numeric prefix "3-" in the substitute part designates the RoHS-compliant variant.

Q: What packaging is available for the substitute part?

A: The substitute part 3-641536-2 is available in bulk packaging, suitable for high-volume production and assembly operations.
