Engineering Selection Recommendations

The 3-641217-2 is a direct functional equivalent to the 641217-2 with no electrical or mechanical compromises. Selection criteria are based on the following factors:

Product Status: The 641217-2 is classified as obsolete, while the 3-641217-2 maintains active product status. Active status ensures continued manufacturing support, quality assurance, and supply chain reliability.

Regulatory Compliance: Both parts satisfy RoHS requirements. The 641217-2 carries ROHS3 compliance, while the 3-641217-2 carries standard RoHS compliance. Both designations confirm lead-free construction and hazardous substance restrictions compliance.

Moisture Sensitivity: Both parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

Export Classification: Both parts are classified as EAR99, confirming identical export control status.

Packaging Consideration: The 641217-2 is supplied in unspecified packaging, while the 3-641217-2 is supplied in bulk packaging. Bulk packaging is standard for active production components and supports higher-volume procurement requirements.

For new designs or component replacement in active systems, the 3-641217-2 is the appropriate selection due to active product status and assured long-term availability.

Frequently Asked Questions (FAQ)

Q: Are the 641217-2 and 3-641217-2 electrically interchangeable?

A: Yes. Both connectors are 2-position receptacles with identical contact pitch (0.156"), contact type (female socket), wire gauge rating (18 AWG), and gold contact finish specifications. They function identically in IDC termination applications.

Q: What is the difference between these two part numbers?

A: The primary difference is product status. The 641217-2 is obsolete, while the 3-641217-2 is active. The 3-641217-2 also specifies bulk packaging, which is standard for active production components. All electrical and mechanical specifications are identical.

Q: Can I use the 3-641217-2 as a direct replacement for the 641217-2?

A: Yes. The 3-641217-2 is a direct substitute with identical connector specifications, contact configuration, and termination method. No design modifications are required.

Q: Are both parts RoHS compliant?

A: Yes. The 641217-2 is ROHS3 compliant, and the 3-641217-2 is RoHS compliant. Both designations confirm compliance with lead-free and hazardous substance restrictions.

Q: What wire gauge does this connector support?

A: Both connectors are rated for 18 AWG wire with IDC termination. The contact pitch of 0.156" and IDC design are optimized for this wire gauge.

Q: Does moisture sensitivity affect storage or handling?

A: No. Both parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity. Standard storage conditions are appropriate.

Q: What is the pitch specification for this connector?

A: The pitch is 0.156" (3.96mm), which defines the center-to-center spacing between the two contact positions. This specification is identical for both the main part and substitute.

Q: Is the locking ramp fastening mechanism the same on both parts?

A: Yes. Both connectors use locking ramp fastening for mechanical retention. The fastening mechanism and interface are identical.
