Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2-640440-3 connector is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• 23-position contact count
• 0.100" (2.54mm) pitch spacing
• Single-row configuration
• IDC termination compatibility with 22 AWG wire gauge
• Contact finish thickness of 80.0µin (2.03µm)

Mechanical Parameters:

• Receptacle connector type with female socket contacts
• Free hanging (in-line) and right-angle mounting capability
• Locking ramp fastening mechanism
• Closed-end housing design
• Red color specification

Environmental & Compliance Parameters:

• Moisture Sensitivity Level 1 (unlimited)
• ECCN EAR99 classification
• HTSUS 8536.69.8000 tariff code

The substitute part 5-640440-3 maintains identical electrical and mechanical specifications while differing in contact finish composition (tin versus tin-lead) and product status (active versus obsolete).

Parameter Comparison

Engineering Selection Recommendations

The 5-640440-3 serves as the direct substitute for the obsolete 2-640440-3 connector. Both parts share identical electrical and mechanical specifications within the MTA-100 series, ensuring functional interchangeability in 23-position IDC applications with 22 AWG cable.

Product Status Consideration: The 2-640440-3 is classified as obsolete, while the 5-640440-3 maintains active product status. For new designs and ongoing production, the 5-640440-3 is the appropriate selection to ensure long-term component availability and supply chain continuity.

Compliance Differentiation: The primary distinction between these parts is regulatory compliance. The 5-640440-3 is RoHS compliant, whereas the 2-640440-3 is RoHS non-compliant. This difference reflects the contact finish composition: the substitute uses pure tin finish instead of tin-lead. For applications subject to RoHS directives or customer requirements mandating RoHS compliance, the 5-640440-3 is the required selection.

Contact Finish: Both parts maintain identical contact finish thickness of 80.0µin (2.03µm). The tin finish of the 5-640440-3 provides equivalent electrical performance and contact reliability compared to the tin-lead finish of the 2-640440-3 within the specified thickness parameters.

Environmental Rating: Both connectors carry MSL 1 (unlimited moisture sensitivity level), indicating no moisture sensitivity restrictions for storage or handling.

Frequently Asked Questions (FAQ)

Q: Can the 5-640440-3 directly replace the 2-640440-3 in existing applications?

A: Yes. The 5-640440-3 is electrically and mechanically equivalent to the 2-640440-3. Both connectors are 23-position receptacles with 0.100" pitch, IDC termination for 22 AWG cable, and identical mounting and fastening specifications. The substitute part maintains the same contact finish thickness and closed-end housing design.

Q: What is the primary difference between these two parts?

A: The main differences are product status and contact finish composition. The 2-640440-3 is obsolete with tin-lead contact finish and RoHS non-compliant status. The 5-640440-3 is active with pure tin contact finish and RoHS compliant status. Both maintain identical electrical and mechanical performance specifications.

Q: Why should I use the 5-640440-3 instead of the 2-640440-3?

A: The 5-640440-3 is the active product in the MTA-100 series. Using the active part ensures component availability for current and future production runs. Additionally, the RoHS compliance of the 5-640440-3 aligns with modern regulatory requirements and customer specifications.

Q: Are there any compatibility concerns when substituting the 5-640440-3 for the 2-640440-3?

A: No compatibility concerns exist. Both connectors share identical pitch, position count, row configuration, mounting type, fastening mechanism, and cable termination method. The contact finish thickness is equivalent at 80.0µin (2.03µm), ensuring consistent electrical performance.

Q: Does the tin finish of the 5-640440-3 affect electrical performance compared to the tin-lead finish of the 2-640440-3?

A: No. Both contact finishes maintain the same thickness specification of 80.0µin (2.03µm). Tin finish provides equivalent electrical conductivity and contact reliability for IDC applications with 22 AWG cable.

Q: What is the packaging difference between these parts?

A: The 2-640440-3 packaging specification is not defined in the available data. The 5-640440-3 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Are both parts suitable for ribbon cable and discrete wire applications?

A: Yes. Both the 2-640440-3 and 5-640440-3 support discrete or ribbon cable termination via IDC method with 22 AWG wire gauge.

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

A: Both connectors carry MSL 1 (unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or use.
