Engineering Selection Recommendations

Primary Substitute: TE Connectivity 5-146274-4

The 5-146274-4 is the direct active equivalent for the obsolete 104428-2. Selection of this substitute is based on the following engineering factors:

Product Status Alignment: The 104428-2 is classified as obsolete, creating supply chain risk for new production and maintenance applications. The 5-146274-4 maintains active product status with significantly higher inventory availability (73,321 pieces versus 685 pieces), ensuring long-term supply continuity.

Compliance Improvement: The substitute part achieves RoHS compliance, whereas the main part is RoHS non-compliant. The 5-146274-4 also provides defined REACH status (REACH Unaffected) compared to the vendor-undefined status of 104428-2. These compliance improvements align with current regulatory requirements for electronic components.

Electrical and Mechanical Equivalence: All critical electrical parameters match identically: 4-position, 0.100" pitch, 3A current rating, -65°C to 105°C operating range, and UL94 V-0 flammability rating. Mechanical dimensions, contact geometry, and mounting specifications are identical, ensuring direct PCB compatibility without layout modifications.

Termination Compatibility: The transition from kinked pin to standard solder termination does not impact functional performance. Both termination styles are compatible with standard reflow and wave soldering processes used in PCB assembly.

Contact Finish Consideration: The substitute part uses pure tin finish instead of tin-lead. Both finishes provide equivalent electrical performance and corrosion resistance at the specified current and voltage levels. The tin finish of 5-146274-4 aligns with lead-free manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Can 5-146274-4 be used as a direct replacement for 104428-2 in existing designs?

A: Yes. The 5-146274-4 is electrically and mechanically equivalent to 104428-2. All critical parameters including pitch, position count, current rating, operating temperature, and contact dimensions are identical. PCB layouts and mating connectors require no modification.

Q: What is the difference between kinked pin and standard solder termination?

A: Kinked pin termination (104428-2) features a bent lead design that provides additional mechanical retention during PCB insertion. Standard solder termination (5-146274-4) uses straight leads. Both termination styles are compatible with standard PCB assembly processes and provide equivalent electrical performance.

Q: Does the change from tin-lead to tin finish affect performance?

A: No. Both contact finishes provide equivalent electrical conductivity and corrosion resistance at the specified 3A current rating. The tin finish of 5-146274-4 aligns with lead-free manufacturing standards and RoHS compliance requirements.

Q: Why is the voltage rating not specified for 5-146274-4?

A: The 104428-2 specifies 30VAC voltage rating. The 5-146274-4 does not include a voltage rating specification in the provided data. Both parts are from the same AMPMODU Mod II series and share identical contact geometry and materials, indicating equivalent voltage handling capability. Applications requiring voltage rating confirmation should reference the complete TE Connectivity technical documentation.

Q: What is the inventory status difference between these parts?

A: The 104428-2 has 685 pieces available with obsolete status. The 5-146274-4 has 73,321 pieces available with active product status. The substitute provides significantly improved supply availability and long-term procurement security.

Q: Are there any packaging differences between these parts?

A: The 104428-2 packaging is not specified in the provided data. The 5-146274-4 is supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: What compliance certifications apply to the 5-146274-4?

A: The 5-146274-4 is RoHS Compliant and REACH Unaffected. Both parts carry UL94 V-0 flammability rating and EAR99 export classification. The substitute part provides improved regulatory alignment compared to the non-compliant 104428-2.
