Parameter Comparison

Engineering Selection Recommendations

Primary Substitution Criteria:

The substitute part 2-640497-4 is electrically and mechanically equivalent to the main part 640497-4 across all critical parameters. Both parts are classified as Active product status and maintain identical electrical ratings, mechanical dimensions, and functional specifications.

Compliance Consideration:

The substitute part 2-640497-4 carries ROHS3 Compliant status, whereas the main part 640497-4 is RoHS non-compliant. This distinction is significant for applications subject to RoHS (Restriction of Hazardous Substances) regulations. The substitute part's enhanced compliance status does not compromise electrical or mechanical performance and may be required for specific regulatory environments.

Contact Finish Difference:

The main part features Tin-Lead contact finish on the post, while the substitute part features Tin contact finish on the post. Both maintain identical finish thickness (150.0µin / 3.81µm) and identical gold mating surface finish. This difference reflects evolving lead-free manufacturing standards and does not affect electrical performance or mechanical compatibility.

Inventory and Availability:

The substitute part 2-640497-4 maintains higher inventory availability (1261 Pcs) compared to the main part 640497-4 (912 Pcs), both in new original condition.

Frequently Asked Questions (FAQ)

Q: Are the 640497-4 and 2-640497-4 connectors physically interchangeable?

A: Yes. Both connectors maintain identical mechanical dimensions, including 2-position configuration, 4.2mm pitch, through-hole mounting, shrouded 4-wall construction, and contact geometry. Physical interchangeability is confirmed across all specified mechanical parameters.

Q: What is the difference between the Tin-Lead and Tin contact finishes on the post?

A: The main part 640497-4 uses Tin-Lead finish, while the substitute part 2-640497-4 uses Tin finish. Both maintain identical finish thickness (150.0µin / 3.81µm). The Tin finish on the substitute part reflects lead-free manufacturing compliance. Both finishes provide equivalent electrical performance and solder joint reliability for the specified 6A current rating and 250VAC voltage rating.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. The RoHS compliance status reflects manufacturing process and material composition standards, not electrical performance. Both parts maintain identical electrical ratings (6A, 250VAC) and operating temperature range (-55°C ~ 105°C). The substitute part's ROHS3 Compliant status is a regulatory advantage for applications in jurisdictions requiring RoHS compliance.

Q: Can I use the 2-640497-4 as a direct replacement for the 640497-4 in existing designs?

A: Yes. The substitute part 2-640497-4 maintains full electrical and mechanical compatibility with the main part 640497-4. All critical parameters including current rating, voltage rating, pitch, mounting type, and contact specifications are identical. The substitute part is suitable for direct replacement in applications currently using the main part.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the 640497-4 and 2-640497-4 operate across the identical temperature range of -55°C to 105°C. No thermal performance differences exist between the two parts.

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

A: Both parts carry Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life without moisture control requirements. No special storage or handling precautions are necessary for either part.
