Substitute Part Grouping Explanation

Substitution of the obsolete TE Connectivity 4-103328-2 is based on strict electrical and mechanical parameter matching within the AMPMODU Mod II series. The substitute part 5-146254-3 maintains identical specifications across all critical dimensions and electrical characteristics:

Matching Parameters:

• Connector type, contact type, and configuration (6-position, 2-row header)
• Mating pitch and row spacing (0.100" / 2.54mm)
• Contact dimensions and geometry (square shape, 0.230" mating length, 0.120" post length)
• Mounting method (through-hole solder termination)
• Fastening mechanism (push-pull)
• Electrical performance (3A current rating, -65°C to 105°C operating range)
• Material compliance (UL94 V-0, RoHS, MSL 1)

The primary distinction between the main part and substitute is product status (obsolete versus active) and insulation material composition (thermoplastic versus liquid crystal polymer), with both materials meeting identical flammability and environmental specifications.

Engineering Selection Recommendations

The TE Connectivity 5-146254-3 is the direct substitute for the obsolete 4-103328-2. Selection of the substitute part is based on the following engineering criteria:

Product Status: The 5-146254-3 maintains active product status with current manufacturing and distribution support, whereas the 4-103328-2 is classified as obsolete. This ensures long-term availability and supply chain continuity for new designs and production requirements.

Electrical and Mechanical Compatibility: Both parts are identical across all critical electrical parameters (3A current rating, -65°C to 105°C operating range) and mechanical dimensions (6-position, 2-row configuration with 0.100" pitch, through-hole solder termination, push-pull fastening). Pin-to-pin compatibility is complete, enabling direct substitution in existing PCB layouts without design modification.

Compliance and Certifications: Both parts meet UL94 V-0 flammability requirements and maintain MSL 1 (unlimited moisture sensitivity level) classification. The substitute part carries ROHS3 compliance, representing current regulatory alignment. Both parts are classified under identical ECCN (EAR99) and HTSUS (8536.69.4040) codes.

Material Specification: The substitute part uses liquid crystal polymer (LCP) insulation material in place of thermoplastic. Both materials satisfy identical flammability and environmental performance standards. LCP provides enhanced dimensional stability and thermal performance characteristics within the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the 5-146254-3 be used as a direct replacement for the 4-103328-2 in existing assemblies?

A: Yes. The 5-146254-3 is electrically and mechanically identical to the 4-103328-2 across all critical parameters. Pin configuration, contact geometry, mating pitch, current rating, and operating temperature range are identical. Direct substitution in existing PCB designs and assemblies is supported without modification.

Q: What is the difference between the thermoplastic insulation in the 4-103328-2 and the LCP insulation in the 5-146254-3?

A: Both insulation materials meet identical UL94 V-0 flammability ratings and environmental specifications. Liquid crystal polymer (LCP) provides improved dimensional stability and thermal performance. Both materials are suitable for the specified -65°C to 105°C operating temperature range and maintain equivalent electrical isolation properties.

Q: Are there packaging differences between these parts?

A: The 4-103328-2 packaging specification is not provided in the available data. The 5-146254-3 is supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility for component selection purposes.

Q: Why is the 4-103328-2 classified as obsolete?

A: Obsolescence classification indicates the part is no longer in active production. The 5-146254-3 represents the current active equivalent within the AMPMODU Mod II series, ensuring access to current manufacturing and supply chain support.

Q: Do both parts meet current regulatory compliance standards?

A: Both parts are RoHS compliant. The 5-146254-3 carries ROHS3 designation, representing alignment with current regulatory requirements. Both parts are classified as EAR99 for export control purposes and carry identical HTSUS commodity codes.

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

A: Both parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions. These connectors do not require special moisture control handling during storage, transportation, or assembly.

Q: Are the contact dimensions and mating lengths identical between the two parts?

A: Yes. Contact length for mating is 0.230" (5.84mm), post length is 0.120" (3.05mm), and overall contact length is 0.440" (11.18mm) for both parts. Insulation height is 0.090" (2.29mm) for both. These dimensions ensure mechanical compatibility with mating connectors and PCB through-hole patterns.
