• Pitch (0.100" / 2.54mm)
• Number of rows (1)
• Cable termination method (IDC)
• Wire gauge compatibility (22 AWG)
• Wire type support (Discrete or Ribbon Cable)

Mechanical Compatibility Parameters:

• Mounting type (Free Hanging In-Line, Right Angle)
• Fastening type (Locking Ramp)
• Feed-through feature

Physical Parameters:

• Contact finish thickness (80.0µin / 2.03µm)
• Base product number (641653)

The substitute part 3-641653-8 maintains full equivalence across all electrical, mechanical, and physical parameters while offering improved product status and regulatory compliance.

Engineering Selection Recommendations

The TE Connectivity 3-641653-8 is the direct substitute for the obsolete 641653-8 model. Selection of the substitute part is based on the following engineering criteria:

Product Status: The 641653-8 is classified as obsolete, making the active-status 3-641653-8 the appropriate replacement for ongoing production and field service applications.

Regulatory Compliance: The 3-641653-8 is RoHS compliant, whereas the original 641653-8 is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulations and environmental compliance requirements.

Electrical and Mechanical Equivalence: Both parts maintain identical specifications across all critical parameters including connector type, position count, pitch, contact type, termination method, wire gauge, mounting configuration, and fastening mechanism. The contact finish thickness remains constant at 80.0µin (2.03µm).

Contact Finish Difference: The primary technical distinction is the contact finish material. The 641653-8 features tin-lead finish, while the 3-641653-8 features tin finish. Both finishes maintain the same thickness specification and are compatible with IDC termination for 22 AWG cable.

Availability: The 3-641653-8 is available in significantly higher inventory (6291 pieces) compared to the 641653-8 (932 pieces), supporting supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the 3-641653-8 be used as a direct replacement for the 641653-8 in existing designs?

A: Yes. The 3-641653-8 is electrically and mechanically equivalent to the 641653-8 across all critical parameters including connector type, position count, pitch, contact type, termination method, wire gauge, and mounting configuration. Both parts are compatible with 22 AWG discrete or ribbon cable and feature identical contact finish thickness.

Q: What is the difference between the tin-lead finish on the 641653-8 and the tin finish on the 3-641653-8?

A: The 641653-8 uses tin-lead contact finish, while the 3-641653-8 uses tin contact finish. Both finishes maintain the same thickness specification of 80.0µin (2.03µm). The tin finish on the 3-641653-8 reflects modern manufacturing standards and RoHS compliance requirements.

Q: Are there any compatibility issues when substituting the 3-641653-8 for the 641653-8?

A: No compatibility issues exist. Both connectors are from the MTA-100 series with identical electrical and mechanical specifications. They support the same cable types, termination methods, and mounting configurations.

Q: Why is the 641653-8 classified as obsolete?

A: The 641653-8 is classified as obsolete by TE Connectivity. The 3-641653-8 is the active replacement part that maintains full functional equivalence while offering improved product status and regulatory compliance.

Q: What is the significance of RoHS compliance for the 3-641653-8?

A: The 3-641653-8 is RoHS compliant, meaning it meets the Restriction of Hazardous Substances directive requirements. This is important for applications subject to RoHS regulations and for organizations with environmental compliance policies. The original 641653-8 is RoHS non-compliant.

Q: Are the packaging specifications different between these two parts?

A: The 641653-8 packaging specification is not provided in the technical data. The 3-641653-8 is supplied in bulk packaging. Specific packaging requirements should be confirmed with the supplier.

Q: Can both parts be used interchangeably in production?

A: Yes. The 3-641653-8 is the direct substitute for the 641653-8 and can be used interchangeably in applications requiring 8-position IDC rectangular receptacle connectors with 22 AWG wire compatibility and 0.100" pitch spacing.
