TE Connectivity 641534-2 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 641534-2 is a 2-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 900 pieces available in new original inventory.

Substitute parts are identified to provide alternatives based on matching electrical and mechanical specifications, particularly when inventory availability, packaging requirements, or compliance status necessitate component selection from equivalent options within the same connector family.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 641534-2 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Rectangular Receptacle)
• Number of positions (2)
• Contact type (Female Socket)
• Pitch (0.100" / 2.54mm)
• Wire gauge (22 AWG)
• Cable termination method (IDC)

Mechanical Compatibility Parameters:

• Mounting type (Free Hanging, In-Line, Right Angle)
• Fastening type (Locking Ramp)
• Number of rows (1)
• Features (Closed End)
• Contact finish thickness (80.0µin / 2.03µm)

Environmental & Regulatory Parameters:

• Series designation (MTA-100)
• Moisture Sensitivity Level (1 - Unlimited)
• ECCN classification (EAR99)
• HTSUS code (8536.69.8000)

The substitute part 3-641534-2 maintains full equivalence across all electrical and mechanical parameters. The primary differences are contact finish composition (tin versus tin-lead) and RoHS compliance status, which do not affect functional interchangeability in applications where these specifications are acceptable.

Parameter Comparison

Engineering Selection Recommendations

641534-2 Selection Criteria: The original part number 641534-2 is appropriate for applications where tin-lead contact finish is specified or required. This part maintains active production status and is suitable for non-RoHS regulated applications or where legacy component specifications mandate tin-lead plating.

3-641534-2 Selection Criteria: The substitute part 3-641534-2 is functionally equivalent and provides the following advantages:

• RoHS compliance for applications subject to RoHS Directive requirements
• Significantly higher inventory availability (18999 pieces versus 900 pieces)
• Bulk packaging option for high-volume procurement
• Identical electrical and mechanical performance characteristics
• Same contact finish thickness and connector geometry

Both parts are active products from TE Connectivity AMP Connectors and maintain identical specifications across all critical electrical and mechanical parameters. Selection between these parts depends on regulatory compliance requirements, packaging needs, and inventory availability rather than functional performance differences.

Frequently Asked Questions (FAQ)

Q: Are the 641534-2 and 3-641534-2 connectors mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including pitch (0.100"), number of positions (2), mounting type (Free Hanging, In-Line, Right Angle), fastening mechanism (Locking Ramp), and closed-end design. They are directly interchangeable in applications where the contact finish specification permits substitution.

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

A: The contact finish composition differs between the two parts. The 641534-2 features tin-lead plating, while the 3-641534-2 features tin plating. Both maintain the same contact finish thickness of 80.0µin (2.03µm). The selection between these finishes depends on application requirements and regulatory compliance mandates.

Q: Why does the 3-641534-2 have significantly higher inventory availability?

A: The 3-641534-2 is supplied in bulk packaging and carries RoHS compliance certification, making it suitable for a broader range of applications and regulatory environments. This typically results in higher stock levels to meet diverse market demand.

Q: Can the 641534-2 be used in RoHS-regulated applications?

A: No. The 641534-2 is marked as RoHS non-compliant due to its tin-lead contact finish. For RoHS-regulated applications, the 3-641534-2 substitute part must be used.

Q: Are both connectors rated for the same wire gauge and termination method?

A: Yes. Both the 641534-2 and 3-641534-2 are rated for 22 AWG wire and use IDC (Insulation Displacement Contact) termination. They accept both discrete and ribbon cable configurations.

Q: What is the Moisture Sensitivity Level for these connectors?

A: Both connectors carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are there any differences in the locking mechanism between these two parts?

A: No. Both connectors use an identical locking ramp fastening type and are mechanically equivalent in all fastening aspects.
