Key Parameters

Substitute Part Grouping Explanation

Substitution of the 647055-2 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Receptacle
• Number of Positions: 2
• Pitch: 0.100" (2.54mm)
• Number of Rows: 1
• Mounting Type: Free Hanging (In-Line), Right Angle
• Cable Termination: IDC
• Wire Gauge: 26 AWG
• Wire Type: Discrete or Ribbon Cable
• Features: Closed End
• Fastening Type: Locking Ramp
• Series: MTA-100

Variable Parameters (Allowable Differences):

• Contact Finish: Tin-Lead or Gold
• Contact Finish Thickness: Varies by finish type
• Product Status: Obsolete or Active
• RoHS Compliance: Non-compliant or Compliant
• Packaging: Bulk or other configurations

The substitute part 3-641239-2 maintains full mechanical and electrical compatibility with the 647055-2 across all mandatory parameters. The primary differences are contact finish material (gold versus tin-lead) and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement in Active Production:

The 3-641239-2 is the appropriate substitute for the obsolete 647055-2. This part maintains identical mechanical and electrical specifications across all functional parameters while offering the following advantages:

• Active Product Status: The 3-641239-2 is currently in active production, ensuring long-term availability and supply chain continuity.
• RoHS3 Compliance: The substitute meets ROHS3 compliance requirements, supporting regulatory and environmental standards applicable to modern manufacturing and distribution.
• Improved Inventory: The 3-641239-2 maintains significantly higher stock levels (8988 Pcs) compared to the obsolete 647055-2 (899 Pcs), reducing procurement lead times.

Contact Finish Consideration:

The 3-641239-2 features gold contact finish (30.0µin) in place of the tin-lead finish (80.0µin) of the 647055-2. Both finishes are compatible with IDC termination and 26 AWG wire applications. Gold contact finish provides enhanced corrosion resistance and is standard in current MTA-100 series production.

Compliance Status:

Applications subject to RoHS3 requirements must transition to the 3-641239-2. The 647055-2 is RoHS non-compliant and unsuitable for new designs or regulated markets.

Frequently Asked Questions (FAQ)

Q: Can the 3-641239-2 be used as a direct replacement for the 647055-2 in existing assemblies?

A: Yes. The 3-641239-2 maintains identical connector geometry, pitch, mounting configuration, and IDC termination specifications. Mechanical and electrical compatibility is confirmed across all functional parameters.

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

A: Both finishes are suitable for IDC termination with 26 AWG wire. Gold finish provides superior corrosion resistance and is the current standard for MTA-100 series production. Tin-lead finish was used in legacy designs. The contact finish does not affect mechanical fit or electrical performance in this connector category.

Q: Is the 3-641239-2 suitable for applications requiring RoHS compliance?

A: Yes. The 3-641239-2 is ROHS3 compliant. The 647055-2 is RoHS non-compliant and cannot be used in applications subject to RoHS requirements.

Q: Are there any packaging differences between the 647055-2 and 3-641239-2?

A: The 647055-2 packaging is not specified in available documentation. The 3-641239-2 is supplied in bulk packaging. Confirm packaging requirements with your procurement specification.

Q: What is the Moisture Sensitivity Level (MSL) for both parts?

A: Both the 647055-2 and 3-641239-2 are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Can I use the 3-641239-2 in new product designs?

A: Yes. The 3-641239-2 is an active product with current manufacturing support. It is the recommended choice for all new designs requiring a 2-position MTA-100 series IDC receptacle connector for 26 AWG cable.

Q: What is the availability status of the 647055-2?

A: The 647055-2 is classified as obsolete. Limited inventory (899 Pcs) remains available. For ongoing production requirements, transition to the 3-641239-2 to ensure supply continuity.
