Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5-146290-3 is determined by strict alignment with the following critical parameters:

Mechanical Compatibility:

• Connector type classification (Header, Breakaway)
• Contact type (Male Pin)
• Number of positions (3)
• Pitch spacing (0.100" / 2.54mm)
• Mounting method (Through Hole)
• Overall contact dimensions and insulation height

Electrical Compatibility:

• Operating temperature range (-65°C ~ 105°C)
• Current rating (3A)
• Contact material (Copper Alloy)
• Contact finish (Tin)

Material & Compliance:

• Insulation material (Liquid Crystal Polymer)
• Flammability rating (UL94 V-0)
• RoHS compliance status
• Moisture sensitivity level (MSL 1)

The substitute part 5-146278-3 shares identical mechanical and electrical specifications with the main part across all critical parameters. The primary distinction is product status (Active vs. Obsolete) and termination method availability (Solder only vs. Press-Fit and Solder).

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5-146278-3 is the direct substitute for the obsolete 5-146290-3. Both connectors are manufactured by TE Connectivity within the AMPMODU Mod II series and share identical electrical, mechanical, and material specifications.

Product Status Consideration: The 5-146290-3 is classified as obsolete, while the 5-146278-3 maintains active product status. Active status ensures ongoing manufacturer support, documented availability, and compliance with current regulatory standards.

Compliance & Certification: Both parts meet UL94 V-0 flammability requirements and maintain MSL 1 moisture sensitivity classification. The 5-146278-3 carries ROHS3 compliance, representing the current regulatory standard, while the 5-146290-3 carries RoHS compliance. Both designations are compatible for applications requiring RoHS adherence.

Termination Method: The primary technical distinction is termination capability. The 5-146290-3 supports both Press-Fit and Solder termination methods, while the 5-146278-3 supports Solder termination only. For applications utilizing solder termination exclusively, the 5-146278-3 provides full functional equivalence. Applications requiring press-fit termination must retain the 5-146290-3 or identify alternative solutions outside this substitute pair.

Supply Chain & Inventory: The 5-146278-3 maintains significantly higher inventory availability (15,876 pieces) compared to the 5-146290-3 (946 pieces), supporting long-term production continuity and reducing procurement lead times.

Frequently Asked Questions (FAQ)

Q: Can the 5-146278-3 directly replace the 5-146290-3 in all applications?

A: The 5-146278-3 provides direct substitution for applications using solder termination. If your design requires press-fit termination capability, the 5-146278-3 does not support this method. Verify your assembly process termination requirements before substitution.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: Obsolete status indicates the 5-146290-3 is no longer in active production and will eventually reach end-of-life. Active status for the 5-146278-3 ensures continued manufacturing, technical support, and regulatory compliance updates. For new designs or long-term production, the active part is preferred.

Q: Are the electrical and mechanical specifications identical between these parts?

A: Yes. Both connectors share identical specifications for connector type, contact configuration, pitch spacing, operating temperature range, current rating, contact materials, and insulation properties. All critical parameters for mechanical and electrical compatibility are matched.

Q: What does ROHS3 compliance mean compared to RoHS compliance?

A: ROHS3 represents the current regulatory standard for restriction of hazardous substances, incorporating the latest EU directives. RoHS compliance refers to earlier versions of the standard. Both designations indicate restriction of hazardous materials; ROHS3 reflects the most current regulatory framework.

Q: Are there packaging differences between these parts?

A: The 5-146290-3 packaging is not specified in available documentation. The 5-146278-3 is supplied in bulk packaging. Confirm packaging requirements with your procurement process, as this may affect handling, storage, and assembly procedures.

Q: Can I use the 5-146278-3 in legacy equipment currently using the 5-146290-3?

A: Yes, provided the equipment assembly process uses solder termination. The identical mechanical and electrical specifications ensure functional compatibility. If the legacy equipment uses press-fit assembly methods, substitution is not suitable.

Q: What is the MSL 1 rating and why is it important?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without special moisture control requirements. Both parts carry this rating, eliminating moisture-related storage constraints and simplifying inventory management.
