TE Connectivity 1-146261-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-146261-3 is a rectangular connector header designed for through-hole mounting applications. This connector is a vertical 26-position header with 2.54mm (0.100") pitch spacing, configured in a 2-row layout. The part operates within the AMPMODU Mod II series and features male pin contacts with gold-plated mating surfaces and tin-lead post finishes.

The 1-146261-3 carries an obsolete product status. Locating equivalent or substitute components is necessary for ongoing production support, maintenance applications, and design continuity where this connector type is specified in existing assemblies.

Parameter Comparison

Engineering Selection Recommendations

The 6-146261-3 is a direct functional substitute for the obsolete 1-146261-3. Both parts share identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: the 1-146261-3 is obsolete, while the 6-146261-3 is active and currently available.

The 6-146261-3 offers improved compliance status with ROHS3 certification compared to the RoHS Compliant designation of the original part. Both parts maintain identical moisture sensitivity levels, export classifications, and tariff codes.

The contact finish on the post differs between the two parts: the 1-146261-3 uses tin-lead, while the 6-146261-3 uses tin. This difference reflects modern manufacturing practices and regulatory compliance trends. Both finishes maintain the same thickness specification of 100.0µin (2.54µm) and are compatible with standard solder assembly processes.

For new designs or ongoing production requiring this connector type, the 6-146261-3 is the appropriate selection due to its active product status and current availability.

Frequently Asked Questions (FAQ)

Q: Can the 6-146261-3 be used as a direct replacement for the 1-146261-3 in existing assemblies?

A: Yes. The 6-146261-3 meets all electrical and mechanical specifications of the 1-146261-3. Both parts are functionally equivalent rectangular connectors within the AMPMODU Mod II series with identical pitch, position count, contact geometry, and operating characteristics.

Q: What is the significance of the contact finish difference between tin-lead and tin?

A: The 1-146261-3 features tin-lead post finish, while the 6-146261-3 uses tin post finish. Both finishes are compatible with standard solder assembly processes and maintain identical thickness specifications. The tin finish on the 6-146261-3 reflects current manufacturing standards and regulatory compliance.

Q: Are there packaging differences between these parts?

A: The 1-146261-3 packaging specification is not provided in the available data. The 6-146261-3 is supplied in bulk packaging. Packaging configuration should be confirmed based on specific procurement requirements.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant status?

A: Both designations indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents the current regulatory standard. The 6-146261-3 carries the more current ROHS3 Compliant certification.

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

A: Yes. Both the 1-146261-3 and 6-146261-3 operate across the identical temperature range of -65°C to 105°C and carry the same UL94 V-0 flammability rating.

Q: What is the current rating for these connectors?

A: Both parts are rated for 3A continuous current. This specification applies uniformly across all 26 positions in the connector.

Q: Are these parts moisture sensitive?

A: Both parts carry Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life without moisture control requirements.
