Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 641120-2 with active equivalent components is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (2)
• Pitch specification (0.156" / 3.96mm)
• Voltage rating (600VAC)
• Operating temperature range (-55°C ~ 105°C)

Mechanical Compatibility Parameters:

• Mounting type (Through Hole)
• Termination method (Solder)
• Shrouding configuration (Shrouded - 1 Wall)
• Contact dimensions (Mating length, post length, overall length)
• Insulation material and height
• Contact shape (Circular)

Compliance Parameters:

• Material flammability rating (UL94 V-0)
• Moisture sensitivity level (MSL 1)

The substitute part 3-641120-2 maintains full equivalence across all specified electrical, mechanical, and compliance parameters, with the primary distinction being active product status and RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 3-641120-2 is a direct functional equivalent to the obsolete 641120-2. Both components share identical electrical specifications, mechanical dimensions, and performance characteristics across all critical parameters. The primary distinction is product status: 641120-2 is obsolete with limited inventory availability, while 3-641120-2 is an active product with substantially higher stock levels (11,386 pieces versus 906 pieces).

An additional advantage of the 3-641120-2 substitute is its RoHS compliance status. The substitute meets RoHS requirements, whereas the original part is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulations or for organizations implementing RoHS-compliant supply chains.

The contact finish on the post differs slightly between the two parts: the original uses Tin-Lead while the substitute uses Tin. This change reflects modern manufacturing practices and environmental compliance trends. Both finishes are compatible with standard solder processes and provide equivalent electrical performance.

For new designs and replacement applications, the 3-641120-2 is the appropriate selection due to its active status, improved compliance profile, and superior availability.

Frequently Asked Questions (FAQ)

Q: Are the 641120-2 and 3-641120-2 mechanically interchangeable?

A: Yes. Both parts maintain identical mechanical specifications including mounting type (through hole), contact dimensions, insulation height, shrouding configuration, and overall form factor. Direct substitution is possible without PCB or assembly modifications.

Q: What is the significance of the contact finish difference (Tin-Lead versus Tin)?

A: The substitute part uses Tin finish on the post instead of Tin-Lead. Both finishes are compatible with standard solder reflow and wave soldering processes. Tin finish reflects current manufacturing standards and environmental compliance practices. No functional difference exists in electrical performance or reliability.

Q: Why is RoHS compliance important for this connector?

A: RoHS compliance indicates the component meets restrictions on hazardous substances. The substitute part 3-641120-2 is RoHS compliant, making it suitable for applications and markets requiring RoHS-certified components. The original 641120-2 is RoHS non-compliant and may not be acceptable for certain regulatory environments or customer specifications.

Q: Can I use the 3-641120-2 in existing designs originally specified for 641120-2?

A: Yes. The 3-641120-2 is a direct substitute with identical electrical and mechanical specifications. No design changes are required. The substitute is fully compatible with existing PCB layouts, mating connectors, and assembly processes.

Q: What is the difference in packaging between these parts?

A: The original 641120-2 packaging specification is not provided in the technical data. The substitute 3-641120-2 is supplied in bulk packaging. Confirm packaging requirements with your procurement or assembly team to ensure compatibility with your receiving and handling processes.

Q: Are the voltage and temperature ratings identical?

A: Yes. Both parts are rated for 600VAC and operate across the identical temperature range of -55°C to 105°C. Electrical performance specifications are fully equivalent.

Q: What is the pitch specification and why is it important?

A: Both parts feature a 0.156" (3.96mm) mating pitch. This specification determines compatibility with mating connectors and PCB footprints. The identical pitch ensures the substitute part mates with existing connector systems without modification.

Q: How many positions does this connector support?

A: Both the 641120-2 and 3-641120-2 are 2-position connectors in a single-row configuration. Position count and arrangement are identical between the original and substitute parts.
