TE Connectivity 641213-4 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity 641213-4 is a shrouded vertical rectangular connector header designed for through-hole mounting in board-to-cable/wire applications. This component features a 4-position configuration with 0.100" (2.54mm) pitch spacing and is part of the MTA-100 series. The part is classified as obsolete, making identification of active equivalent components essential for ongoing production and maintenance applications. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct compatibility without circuit redesign or board modification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector headers is determined by strict equivalence across electrical and mechanical parameters. The following criteria establish whether a part qualifies as a direct substitute for the TE Connectivity 641213-4:

Critical Matching Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (4)
• Pitch spacing (0.100" / 2.54mm)
• Mounting method (Through Hole)
• Shrouding configuration (Shrouded - 1 Wall)
• Termination method (Solder)
• Voltage rating (250VAC minimum)
• Operating temperature range (-55°C ~ 105°C)
• Material flammability rating (UL94 V-0)

The substitute part 3-641213-4 meets all critical parameters and is therefore classified as a direct equivalent. The primary distinction between these parts is product status and packaging configuration, not functional or electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 3-641213-4 is the direct functional equivalent to the obsolete 641213-4 model. Both components share identical electrical and mechanical specifications across all critical parameters including connector type, contact configuration, pitch spacing, mounting method, and environmental ratings.

Product Status Consideration: The 641213-4 is classified as obsolete, while the 3-641213-4 maintains active product status with significantly higher inventory availability (4989 pieces versus 919 pieces). This status difference reflects manufacturing continuity and supply chain reliability.

Compliance Variation: The substitute part 3-641213-4 is RoHS Compliant, whereas the main part carries a "Not applicable" RoHS status. This distinction reflects the obsolete classification of the original part. For applications requiring RoHS compliance, the 3-641213-4 is the appropriate selection.

Contact Finish Variation: The post contact finish differs between the two parts. The 641213-4 uses Tin-Lead finish, while the 3-641213-4 uses Tin finish. Both finishes maintain identical thickness specifications (150.0µin / 3.81µm) and are compatible with standard solder termination processes.

Packaging: The 3-641213-4 is supplied in bulk packaging, whereas the original part packaging is not specified. This packaging difference does not affect functional compatibility.

For new designs and ongoing production requiring this connector type, the 3-641213-4 is the recommended selection based on active product status and RoHS compliance.

Frequently Asked Questions (FAQ)

Q: Can the 3-641213-4 be used as a direct replacement for the 641213-4 in existing applications?

A: Yes. The 3-641213-4 is electrically and mechanically equivalent to the 641213-4. All critical parameters including connector type, position count, pitch spacing, voltage rating, temperature range, and flammability rating are identical. Direct substitution is possible without circuit modification or board redesign.

Q: What is the significance of the contact finish difference between Tin-Lead and Tin?

A: Both finishes are applied at identical thickness (150.0µin / 3.81µm) and are compatible with standard solder termination processes. The Tin finish on the 3-641213-4 reflects modern manufacturing practices and RoHS compliance requirements. This change does not affect electrical performance or solderability.

Q: Why does the 641213-4 have "Not applicable" RoHS status while the 3-641213-4 is RoHS Compliant?

A: The 641213-4 is classified as obsolete, and RoHS status is not assigned to discontinued products. The 3-641213-4 is an active product manufactured to current RoHS standards. For applications requiring RoHS compliance documentation, the 3-641213-4 is the appropriate choice.

Q: Are there any differences in the mating interface between these two parts?

A: No. Both parts feature identical mating contact specifications: 0.295" (7.49mm) mating length, gold finish at 30.0µin (0.76µm) thickness, square contact shape, and 0.100" (2.54mm) pitch spacing. Mating compatibility with corresponding receptacles is identical.

Q: What is the difference between the packaging configurations?

A: The 641213-4 packaging is not specified in available documentation. The 3-641213-4 is supplied in bulk packaging. Packaging configuration does not affect component functionality or electrical characteristics. Selection between these parts should be based on functional requirements and product availability, not packaging format.

Q: Can both parts be used interchangeably in the same circuit board design?

A: Yes. The 3-641213-4 is a direct functional equivalent suitable for use in any application designed for the 641213-4. The identical through-hole mounting specifications, solder termination method, and dimensional characteristics ensure mechanical and electrical compatibility without design modification.

Q: What is the current availability status of these parts?

A: The 641213-4 (obsolete) has 919 pieces in stock. The 3-641213-4 (active) has 4989 pieces in stock. For new production requirements, the 3-641213-4 offers superior supply chain continuity due to its active product status.
