TE Connectivity AMP Connectors 641211-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 641211-3 is a rectangular connector header designed for through-hole mounting applications. This connector is a vertical 3-position header with 0.100" (2.54mm) pitch spacing, commonly used in board-to-cable and board-to-wire configurations. The part operates within the MTA-100 series and features male pin contacts with gold-plated mating surfaces and tin-lead plated posts.

The 641211-3 carries an obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production and maintenance requirements for legacy systems utilizing this connector specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 641211-3 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 3
• Number of Rows: 1
• Pitch - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder
• Operating Temperature Range: -55°C ~ 105°C
• Voltage Rating: 250VAC
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

Acceptable Variation Parameters:

• Product Status: Active status preferred for ongoing availability
• Packaging: Bulk or standard packaging acceptable
• Contact Finish - Post: Tin or Tin-Lead both acceptable (both provide equivalent solder joint reliability)

The substitute part 3-641211-3 meets all mandatory matching parameters and represents a direct functional equivalent with improved supply chain status.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 3-641211-3 is a direct functional equivalent to the 641211-3 and is suitable for component replacement in all applications where the original part was specified.

Primary Advantage: The 3-641211-3 carries an Active product status, ensuring continued availability and supply chain support. The original 641211-3 is classified as Obsolete, which presents long-term sourcing challenges for production and maintenance activities.

Compliance Equivalence: Both parts maintain identical compliance certifications including ROHS3 compliance, REACH Unaffected status, and UL94 V-0 flammability rating. No regulatory or certification barriers exist for substitution.

Contact Finish Consideration: The substitute part features tin-plated posts compared to the tin-lead plating on the original part. Both finishes provide equivalent solder joint reliability and mechanical performance within the specified operating temperature range of -55°C to 105°C. This variation reflects industry-wide transition toward lead-free manufacturing practices while maintaining functional equivalence.

Packaging Difference: The substitute is supplied in bulk packaging compared to standard packaging for the original part. This represents a procurement variation only and does not affect connector performance or compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 3-641211-3 be used as a direct replacement for the 641211-3 in existing designs?

A: Yes. The 3-641211-3 is a direct functional equivalent. All critical electrical and mechanical parameters match the original specification. The connector will mate with the same receptacle contacts and perform identically within the specified operating conditions.

Q: What is the difference between the tin-lead post finish on the original part and the tin finish on the substitute?

A: Both finishes provide equivalent solder joint reliability and mechanical performance. Tin plating is the industry standard for lead-free manufacturing. The substitute's tin finish meets the same solderability and corrosion resistance requirements as the original tin-lead finish across the full operating temperature range.

Q: Why is the original 641211-3 marked as Obsolete?

A: Obsolete status indicates the part is no longer in active production. The 3-641211-3 represents the current production equivalent within the MTA-100 series and is the recommended source for new procurement.

Q: Are there any compatibility issues with the bulk packaging of the substitute part?

A: No. Bulk packaging is a procurement format only and does not affect connector specifications, performance, or compatibility. The connector itself is identical to the original part.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the 641211-3 and 3-641211-3 are ROHS3 compliant, REACH Unaffected, and carry UL94 V-0 flammability ratings. No compliance barriers exist for substitution.

Q: What is the current inventory status of the substitute part?

A: The 3-641211-3 has 3566 pieces in stock as new original inventory, compared to 1069 pieces for the obsolete original part. The substitute offers superior supply chain availability.

Q: Can the 3-641211-3 be used in applications requiring the full -55°C to 105°C operating temperature range?

A: Yes. The substitute part is rated for the identical operating temperature range and maintains full performance across this specification.
