TE Connectivity AMP Connectors 641213-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 641213-3 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 general-purpose board-to-cable and board-to-wire interconnect applications. The part operates within the MTA-100 series and features shrouded 1-wall construction with gold-plated mating contacts and tin-lead plated posts.

The 641213-3 carries an obsolete product status. Locating equivalent and substitute parts is necessary to support ongoing maintenance, repair, and production requirements for legacy systems and equipment utilizing this connector specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 641213-3 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Pitch spacing (0.100" / 2.54mm)
• Number of positions (3)
• Number of rows (1)
• Mounting method (Through Hole)
• Termination method (Solder)
• Shrouding configuration (Shrouded - 1 Wall)
• Operating temperature range (-55°C ~ 105°C)
• Voltage rating (250VAC)
• Flammability rating (UL94 V-0)
• Contact material (Copper Alloy)
• Insulation material (Thermoplastic)

The substitute part 3-641213-3 maintains full equivalence across all mandatory parameters. The primary distinction between the main part and its substitute is product status (obsolete versus active) and packaging configuration (standard versus bulk), along with minor contact finish post material variation (tin-lead versus tin) and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 3-641213-3 is functionally equivalent to the obsolete 641213-3 across all critical electrical and mechanical parameters. The substitute maintains identical connector geometry, contact configuration, pitch spacing, and operating specifications.

The primary advantage of selecting 3-641213-3 is its active product status, ensuring ongoing availability and supply chain continuity. The substitute carries RoHS Compliant certification, whereas the original part lists RoHS status as not applicable. Both parts share identical electrical ratings, temperature operating range, and flammability certification.

The contact finish on the post differs between the two parts: the original uses tin-lead plating while the substitute uses tin plating. Both maintain the same finish thickness specification of 150.0µin (3.81µm). The mating contact finish remains gold-plated at 30.0µin (0.76µm) on both parts.

For applications requiring legacy component compatibility or where tin-lead plating is specifically mandated, the original 641213-3 remains the appropriate selection. For new designs or applications where RoHS compliance is required, the 3-641213-3 substitute is the suitable choice.

Frequently Asked Questions (FAQ)

Q: Are the 641213-3 and 3-641213-3 mechanically interchangeable?

A: Yes. Both parts share identical connector geometry, contact spacing, mounting footprint, and through-hole termination specifications. The physical dimensions and board-level interface are equivalent.

Q: What is the difference in contact finish between these two parts?

A: The original 641213-3 features tin-lead plating on the post contacts, while the substitute 3-641213-3 uses tin plating. Both maintain the same finish thickness of 150.0µin (3.81µm). The mating contacts on both parts are gold-plated at 30.0µin (0.76µm).

Q: Can I use the 3-641213-3 as a direct replacement in existing assemblies?

A: The 3-641213-3 is electrically and mechanically equivalent to the 641213-3. Compatibility depends on specific application requirements regarding RoHS compliance and contact finish material preferences. For applications where tin-lead plating is explicitly required, the original part is necessary.

Q: What is the significance of the product status difference?

A: The 641213-3 is classified as obsolete, indicating it is no longer in active production. The 3-641213-3 is active, meaning it remains in current production with ongoing availability. For long-term supply assurance, the active substitute is preferable.

Q: Are there any electrical performance differences between these connectors?

A: No. Both parts operate at identical voltage ratings (250VAC), support the same current capacity (varies by wire gauge), and function across the same temperature range (-55°C ~ 105°C). Electrical performance is equivalent.

Q: What does the packaging difference mean?

A: The original 641213-3 is supplied in standard packaging, while the 3-641213-3 is available in bulk packaging. This affects order quantities and handling but does not impact connector performance or compatibility.

Q: Are both parts suitable for general-purpose applications?

A: Yes. Both the 641213-3 and 3-641213-3 are rated for general-purpose applications and carry UL94 V-0 flammability certification, making them suitable for standard industrial and commercial interconnect requirements.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts carry Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without special moisture control measures during storage or handling.
