Key Parameters

Substitute Part Grouping Explanation

Substitution between the main part 641120-5 and the identified substitute 3-641120-5 is based on strict equivalence of the following critical parameters:

Electrical Compatibility Parameters:

• Pitch - Mating: 0.156" (3.96mm)
• Number of Positions: 5
• Contact Type: Male Pin
• Voltage Rating: 600VAC
• Operating Temperature Range: -55°C ~ 105°C

Mechanical Compatibility Parameters:

• Connector Type: Header
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Friction Lock
• Shrouding: Shrouded - 1 Wall
• Contact Shape: Circular
• Insulation Material: Thermoplastic, Glass Filled
• Material Flammability Rating: UL94 V-0

Dimensional Parameters:

• Contact Length - Mating: 0.400" (10.16mm)
• Contact Length - Post: 0.125" (3.18mm)
• Overall Contact Length: 0.650" (16.51mm)
• Insulation Height: 0.425" (10.80mm)

The substitute part 3-641120-5 maintains identical specifications across all electrical, mechanical, and dimensional parameters. The primary difference is packaging format (Bulk versus standard packaging) and compliance status variation.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (641120-5): The 641120-5 is suitable for applications where RoHS non-compliant components are acceptable. This part maintains Active product status and is available in standard packaging with 1053 pieces in stock.

Substitute Part Selection (3-641120-5): The 3-641120-5 is the direct functional equivalent and is recommended for applications requiring ROHS3 compliance. This substitute maintains all electrical and mechanical specifications while offering improved regulatory compliance. The part is available in Bulk packaging with 756 pieces in stock.

Contact Finish Consideration: The main part features Tin-Lead post finish, while the substitute features Tin post finish. Both finishes are functionally equivalent for solder termination applications and do not affect electrical or mechanical performance.

Selection Criteria:

• Select 641120-5 for non-regulated applications or where legacy component specifications are required
• Select 3-641120-5 for applications subject to ROHS3 regulatory requirements or for new designs requiring enhanced compliance posture
• Both parts are interchangeable from electrical and mechanical perspectives
• Packaging format differs (standard versus Bulk); verify procurement requirements before selection

Frequently Asked Questions (FAQ)

Q: Are the 641120-5 and 3-641120-5 electrically interchangeable?

A: Yes. Both parts operate at 600VAC, support the same current rating (varies by wire gauge), and maintain identical operating temperature ranges of -55°C to 105°C. The electrical performance is equivalent.

Q: What is the difference between these two parts?

A: The primary differences are RoHS compliance status and packaging format. The 641120-5 is RoHS non-compliant with standard packaging, while the 3-641120-5 is ROHS3 compliant with Bulk packaging. The contact finish on the post differs (Tin-Lead versus Tin), but both are functionally equivalent for solder termination.

Q: Can I use the 3-641120-5 as a direct replacement for the 641120-5?

A: Yes. The 3-641120-5 is a direct substitute with identical mechanical and electrical specifications. All dimensional parameters, contact configurations, and performance characteristics are equivalent.

Q: Does the Tin versus Tin-Lead post finish affect solderability?

A: No. Both Tin and Tin-Lead finishes are suitable for solder termination. The Tin finish on the 3-641120-5 substitute is functionally equivalent for this application.

Q: Which part should I select for new designs?

A: For new designs, the 3-641120-5 is recommended due to ROHS3 compliance, which aligns with current regulatory requirements and industry standards. Both parts are Active status and suitable for production use.

Q: Are there any mechanical compatibility issues between these parts?

A: No. Both parts feature identical shrouding (Shrouded - 1 Wall), mounting type (Through Hole), contact shape (Circular), and all dimensional specifications. They are mechanically interchangeable.

Q: What is the pitch specification for these connectors?

A: Both parts feature a 0.156" (3.96mm) mating pitch, which is the standard spacing for the MTA-156 series. This specification is identical across both parts.

Q: Can these parts be used in industrial applications?

A: Yes. Both the 641120-5 and 3-641120-5 are rated for general purpose and industrial applications. The UL94 V-0 flammability rating applies to both parts, meeting industrial safety requirements.

Q: What is the inventory status for each part?

A: The 641120-5 has 1053 pieces in stock (standard packaging), while the 3-641120-5 has 756 pieces in stock (Bulk packaging). Verify availability based on your procurement timeline and packaging requirements.
