Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 1-104353-1 are identified based on strict equivalence of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Header, Breakaway
• Contact Type: Male Pin
• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 22
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole, Right Angle
• Contact Finish - Mating: Gold
• Material Flammability Rating: UL94 V-0
• Insulation Color: Black

The substitute parts listed below satisfy all mandatory matching parameters. Variations in contact length, insulation height, and post finish thickness remain within acceptable tolerances for board-to-board and cable connection applications. Operating temperature ranges and current/voltage ratings are provided where available for engineering evaluation.

Engineering Selection Recommendations

TE Connectivity 1-104353-1 (Obsolete)

The original part is no longer in active production. Replacement with an active equivalent is required for new designs and ongoing component procurement.

Molex 0010894226 (Active)

The Molex 0010894226 is an active product with ROHS3 compliance, offering improved environmental regulatory alignment compared to the original part. This connector maintains all critical mechanical and electrical parameters required for direct substitution. The contact length variations (mating contact 0.240" versus 0.230" original, post contact 0.110" versus 0.120" original) and insulation height difference (0.220" versus 0.238" original) are within acceptable tolerances for standard through-hole board mounting applications. Current and voltage ratings are not specified for this part; engineering evaluation against application requirements is necessary. The Molex part is packaged in tube format.

3M 2322-5121-TG (Active)

The 3M 2322-5121-TG is an active product with identical mating contact length (0.230") and matching post contact length (0.110") to the Molex alternative. This connector maintains all critical mechanical and electrical parameters. The operating temperature range (-55°C to 105°C) is narrower than the original part (-65°C to 105°C) by 10°C at the lower limit. Current rating is specified at 3A, matching the original part. The contact finish thickness on mating surfaces is reduced (10.0µin versus 30.0µin original), which may affect long-term contact reliability in high-cycle mating applications. RoHS non-compliance status matches the original part.

Compliance Considerations

For applications requiring RoHS3 compliance, the Molex 0010894226 is the appropriate selection. For applications requiring maintenance of original RoHS status or where compliance is not a constraint, both Molex and 3M alternatives are suitable. Temperature range requirements below -55°C necessitate evaluation of the 3M part against application specifications, as the lower operating limit is 10°C higher than the original.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0010894226 be used as a direct replacement for the TE Connectivity 1-104353-1?

A: Yes. The Molex 0010894226 satisfies all mandatory matching parameters including connector type, contact type, pitch, position count, row configuration, mounting type, contact finish, and flammability rating. Contact length and insulation height variations are within acceptable tolerances for through-hole board mounting. Current and voltage ratings are not specified for the Molex part; verify against application requirements.

Q: Can the 3M 2322-5121-TG be used as a direct replacement for the TE Connectivity 1-104353-1?

A: Yes. The 3M 2322-5121-TG satisfies all mandatory matching parameters. The operating temperature range is -55°C to 105°C, which is 10°C narrower at the lower limit than the original part (-65°C to 105°C). Applications requiring operation below -55°C require engineering evaluation. Contact finish thickness on mating surfaces is reduced (10.0µin versus 30.0µin original).

Q: What are the key differences between the Molex and 3M substitute parts?

A: The Molex 0010894226 offers ROHS3 compliance, while the 3M 2322-5121-TG maintains RoHS non-compliant status matching the original part. Mating contact length differs (Molex 0.240" versus 3M 0.230" matching original). Insulation material differs (Molex polyester glass-filled versus 3M thermoplastic glass-filled). Operating temperature range is not specified for Molex; 3M specifies -55°C to 105°C. Contact finish thickness on mating surfaces is 30.0µin (Molex) versus 10.0µin (3M).

Q: Are there packaging differences between the substitute parts?

A: Yes. The Molex 0010894226 is packaged in tube format. The 3M 2322-5121-TG packaging is not specified in the available data. The original TE Connectivity part packaging is also not specified. Verify packaging requirements for your procurement and assembly processes.

Q: What should I consider when selecting between the substitute parts?

A: Selection depends on regulatory compliance requirements (ROHS3 compliance favors Molex), operating temperature range (original -65°C lower limit requires evaluation of 3M's -55°C limit), contact finish durability (original and Molex specify 30.0µin mating finish versus 3M's 10.0µin), and availability. Verify current and voltage ratings against application requirements, as these are not specified for the Molex part.

Q: Are the contact dimensions compatible with existing mating connectors designed for the TE Connectivity 1-104353-1?

A: Contact length variations exist between the substitute parts and original. The Molex mating contact is 0.240" (versus 0.230" original), and both Molex and 3M post contacts are 0.110" (versus 0.120" original). These variations are within standard tolerances for 0.100" pitch connector systems. Verify compatibility with specific mating connector specifications if critical contact engagement is required.

Q: What is the significance of the contact finish thickness differences?

A: The original TE Connectivity part and Molex substitute specify 30.0µin (0.76µm) gold plating on mating contacts. The 3M part specifies 10.0µin (0.25µm). Thicker plating generally provides longer contact life and better corrosion resistance in high-cycle mating applications. Applications with frequent mating cycles should consider this difference.
