Engineering Selection Recommendations

Primary Recommendation: TE Connectivity 5-146253-3

The TE Connectivity 5-146253-3 is the manufacturer-recommended upgrade from the obsolete 104432-3. This part maintains identical specifications for all critical mating parameters including pitch, position count, row spacing, and contact geometry. The 5-146253-3 is active in production with ROHS3 compliance, addressing regulatory requirements that the original part does not meet. The insulation material has been upgraded from thermoplastic to Liquid Crystal Polymer (LCP), providing improved thermal and mechanical performance. Contact finish on the post has been changed from tin-lead to tin, aligning with modern RoHS requirements. This part is the direct functional equivalent and is recommended as the primary replacement.

Secondary Recommendations: Molex C-Grid Series

The Molex C-Grid 70280 series (part numbers 0010897063 and 0010977066) and C-Grid 70287 series (part number 0702871148) provide cross-manufacturer alternatives with full electrical and mechanical compatibility. These parts maintain all critical interface parameters and are ROHS3 compliant. The C-Grid III 90131 series (part numbers 0901310763 and 0901310923) offers additional options with ROHS3 compliance, though contact length specifications differ slightly. All Molex alternatives are active in production with unlimited moisture sensitivity rating.

Tertiary Recommendations: 3M, Amphenol ICC, and Preci-Dip

The 3M 2306-6221-TP, Amphenol ICC 68481-106HLF, and Preci-Dip 892-18-006-10-001101 provide additional cross-manufacturer alternatives. The 3M part maintains the original thermoplastic insulation material but is RoHS non-compliant. The Amphenol ICC part features phosphor bronze contacts and extended operating temperature range to 130°C. The Preci-Dip part offers the widest voltage rating specification at 150VDC and operates across -55°C to 125°C. All three are active in production and suitable for applications where specific material or performance characteristics are required.

Compliance Considerations

For applications requiring RoHS compliance, the TE Connectivity 5-146253-3, all Molex alternatives, Amphenol ICC 68481-106HLF, and Preci-Dip 892-18-006-10-001101 are compliant. The 3M 2306-6221-TP is RoHS non-compliant and should be selected only for applications where RoHS compliance is not required.

Frequently Asked Questions (FAQ)

Q: Can the obsolete 104432-3 be directly replaced with the TE Connectivity 5-146253-3?

A: Yes. The 5-146253-3 maintains identical specifications for all critical mating parameters: 0.100" (2.54mm) pitch, 6 positions in 2 rows, 0.100" row spacing, square contact shape, and push-pull fastening. The primary differences are material upgrades (LCP insulation, tin post finish) and ROHS3 compliance. The part is functionally equivalent for board-to-board and cable interconnection applications.

Q: What are the key differences between the TE Connectivity 5-146253-3 and Molex alternatives?

A: The TE Connectivity 5-146253-3 is the same manufacturer as the original part and maintains identical contact length specifications (0.318" mating, 0.125" post). Molex C-Grid 70280 and 70287 series parts have slightly different contact lengths (0.320" mating, 0.110" post for 70280; 0.125" post for 70287) and use glass-filled LCP insulation. Molex C-Grid III 90131 series parts have shorter contact lengths (0.266" mating, 0.114" post) and use glass-filled polyester insulation. All maintain the required 2.54mm pitch and 6-position configuration.

Q: Are there packaging differences between substitute parts?

A: Yes. The original 104432-3 packaging is not specified. The TE Connectivity 5-146253-3 is supplied in bulk packaging. Molex parts are supplied in bulk or tray packaging. The 3M 2306-6221-TP packaging is not specified. Amphenol ICC 68481-106HLF is supplied in bag packaging. Preci-Dip 892-18-006-10-001101 is supplied in bulk packaging. Packaging selection should be based on assembly process requirements and inventory management practices.

Q: Which substitute part has the widest operating temperature range?

A: The Amphenol ICC 68481-106HLF operates across -65°C to 130°C, providing the widest temperature range. The original 104432-3 and TE Connectivity 5-146253-3 operate across -65°C to 105°C. Molex parts do not specify operating temperature. The 3M 2306-6221-TP operates across -55°C to 105°C. The Preci-Dip 892-18-006-10-001101 operates across -55°C to 125°C.

Q: What is the difference between the Molex C-Grid 70280 and C-Grid III 90131 series?

A: The C-Grid 70280 series (0010897063, 0010977066) features copper alloy contacts with contact lengths of 0.320" mating and 0.110" post, and uses glass-filled LCP insulation. The C-Grid III 90131 series (0901310763, 0901310923) features brass contacts with contact lengths of 0.266" mating and 0.114" post, and uses glass-filled polyester insulation. Both maintain the 2.54mm pitch and 6-position configuration. The C-Grid 70280 series is more closely matched to the original part's contact length specifications.

Q: Are all substitute parts ROHS compliant?

A: Most substitute parts are ROHS3 compliant: TE Connectivity 5-146253-3, all Molex alternatives, Amphenol ICC 68481-106HLF, and Preci-Dip 892-18-006-10-001101. The 3M 2306-6221-TP is RoHS non-compliant. The original 104432-3 is RoHS non-compliant. For applications requiring RoHS compliance, select from the compliant alternatives listed above.

Q: What contact material differences exist among the substitutes?

A: The original 104432-3 uses copper alloy contacts. The TE Connectivity 5-146253-3 uses copper alloy contacts. Molex C-Grid 70280 and 70287 series use copper alloy contacts. Molex C-Grid III 90131 series use brass contacts. The 3M 2306-6221-TP uses copper alloy contacts. Amphenol ICC 68481-106HLF uses phosphor bronze contacts. Preci-Dip 892-18-006-10-001101 uses brass contacts. All materials are suitable for the specified 3A current rating and push-pull fastening application.

Q: Can I use a substitute part with different contact finish specifications?

A: Contact finish differences do not prevent functional substitution. The original 104432-3 has gold-plated mating contacts (30.0µin) and tin-lead post finish (100.0µin). Substitute parts maintain gold or tin mating contact finishes with varying thicknesses (10.0µin to 118.1µin). Post finishes are tin or tin-lead with varying thicknesses. These variations do not affect electrical performance for the specified 3A current and 30VAC (or unspecified) voltage ratings. Selection should be based on application requirements for corrosion resistance and contact reliability.

Q: What is the significance of the contact length differences?

A: Contact length variations affect mating depth and mechanical engagement with corresponding socket contacts. The original 104432-3 has 0.318" mating contact length and 0.125" post length. The TE Connectivity 5-146253-3 maintains these exact specifications. Molex C-Grid 70280 and 70287 series have 0.320" mating length (0.002" longer) and 0.110" or 0.125" post length. Molex C-Grid III 90131 series have 0.266" mating length (0.052" shorter). These differences may affect compatibility with existing mating connectors. Verify mating connector specifications before substitution.
