Parameter Comparison

Engineering Selection Recommendations

The substitute part 5-146280-8 is the direct equivalent for the obsolete 146280-8 based on product status and compliance certifications. The substitute part is currently active and maintains full electrical and mechanical compatibility with the original specification.

Compliance Considerations:

The main part 146280-8 carries RoHS Compliant status, while the substitute part 5-146280-8 carries ROHS3 Compliant status, indicating updated regulatory alignment. Both parts maintain UL94 V-0 flammability rating and identical MSL classification of 1 (Unlimited).

Contact Finish Difference:

The primary technical difference between the two parts is the contact finish on the post: the original part specifies Tin-Lead, while the substitute specifies Tin. This change reflects industry-wide transition toward lead-free manufacturing practices and is consistent with RoHS3 compliance requirements. The mating contact finish (Gold) and all other electrical and mechanical parameters remain identical.

Inventory and Availability:

The substitute part 5-146280-8 offers significantly higher inventory availability (8881 pcs versus 1070 pcs) and active product status, ensuring long-term procurement viability for new designs and production requirements.

Frequently Asked Questions (FAQ)

Q: Can the 5-146280-8 substitute directly for the 146280-8 in existing designs?

A: Yes. The 5-146280-8 maintains identical electrical and mechanical specifications across all critical parameters including pitch, number of positions, contact type, mounting method, current rating, and operating temperature range. The connector is a direct functional equivalent suitable for board-to-board and cable applications.

Q: What is the significance of the contact finish change from Tin-Lead to Tin?

A: The change from Tin-Lead to Tin reflects compliance with lead-free manufacturing standards and RoHS3 regulations. This change does not affect electrical performance or mechanical compatibility. The mating contact finish remains Gold with identical thickness specifications.

Q: Are there any compatibility concerns with PCB assembly processes?

A: No compatibility concerns exist. Both parts use identical solder termination methods and through-hole mounting specifications. The lead-free Tin finish on the substitute part is compatible with standard lead-free solder reflow processes used in modern PCB assembly.

Q: Why is the substitute part listed as "Bulk" packaging while the original part packaging is not specified?

A: The packaging designation indicates the form in which the substitute part is supplied. Bulk packaging is standard for active production parts and does not affect the connector's electrical or mechanical performance. Specific packaging quantities should be confirmed with the supplier based on procurement requirements.

Q: What is the difference in RoHS compliance between the two parts?

A: The original part carries RoHS Compliant status, while the substitute carries ROHS3 Compliant status. ROHS3 represents the current regulatory standard with updated substance restrictions. Both parts meet lead-free and hazardous substance requirements; the substitute reflects the latest compliance certification.

Q: Is the substitute part suitable for new product designs?

A: Yes. The 5-146280-8 is an active product with full compliance certifications and significantly higher inventory availability. It is the recommended choice for new designs requiring 8-position, 2.54mm pitch rectangular connectors in the AMPMODU Mod II series.

Q: Are there any temperature or current rating differences between the parts?

A: No. Both parts maintain identical operating temperature range (-65°C ~ 105°C) and current rating (3A). All thermal and electrical performance specifications are equivalent.
