Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 103233-3 is determined by strict equivalence across the following critical parameters: connector type (Header), contact type (Male Pin), number of positions (8), number of rows (2), mating pitch (0.100"/2.54mm), row spacing (0.100"/2.54mm), mounting type (Through Hole), termination method (Press-Fit, Solder), fastening type (Push-Pull), contact shape (Square), mating contact finish (Gold), and material flammability rating (UL94 V-0).

The substitute parts identified below maintain these core electrical and mechanical specifications. Variations in contact length, insulation height, contact material composition, and post contact finish are secondary parameters that do not preclude functional substitution when the primary parameters align. All substitute parts support the same board-to-board or cable interconnection style and unshrouded configuration.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (5-103233-3): The TE Connectivity part number 5-103233-3 is the primary direct equivalent to 103233-3. Both parts belong to the AMPMODU Mod II series and share identical electrical and mechanical specifications. The 5-103233-3 maintains Active product status, ensuring ongoing availability and supply chain support. The primary distinction is RoHS compliance status: 5-103233-3 is RoHS Compliant, whereas 103233-3 is RoHS non-compliant. For applications requiring RoHS compliance, 5-103233-3 is the recommended replacement. The contact finish on the post differs slightly (Tin versus Tin-Lead), which does not affect functional compatibility.

Cross-Manufacturer Alternatives: The Amphenol ICC part 10077239-108LF and Samtec part PHT-104-02-L-D are functionally compatible substitutes that meet all critical electrical and mechanical parameters. Both parts are RoHS Compliant and maintain Active product status. The 10077239-108LF operates across an extended temperature range (-65°C ~ 130°C) compared to the main part (-55°C ~ 125°C). The PHT-104-02-L-D supports a higher current rating (4.8A per Contact) and utilizes Liquid Crystal Polymer insulation material. Selection between these alternatives depends on specific application requirements regarding temperature range, current capacity, and insulation material properties.

Frequently Asked Questions (FAQ)

Q: Can 5-103233-3 be used as a direct replacement for 103233-3?

A: Yes. The 5-103233-3 is a direct equivalent with identical connector type, position count, pitch spacing, mounting method, and termination specifications. Both parts are mechanically and electrically interchangeable. The primary difference is RoHS compliance status, with 5-103233-3 being RoHS Compliant.

Q: What are the key differences between the TE Connectivity substitutes and cross-manufacturer alternatives?

A: TE Connectivity parts (103233-3 and 5-103233-3) use Copper Alloy contacts, while Amphenol ICC (10077239-108LF) and Samtec (PHT-104-02-L-D) use Phosphor Bronze contacts. The Samtec part supports higher current capacity (4.8A per Contact versus 3A) and features Liquid Crystal Polymer insulation. The Amphenol part operates across a wider temperature range (-65°C ~ 130°C).

Q: Are there packaging differences between these parts?

A: Yes. The 103233-3, 5-103233-3, and 10077239-108LF are supplied in Bulk packaging. The PHT-104-02-L-D is supplied in Tube packaging. Packaging format may affect handling, storage, and integration into manufacturing processes.

Q: Do all substitute parts maintain the same contact length specifications?

A: No. Contact lengths vary across the substitute parts. The 103233-3 has an Overall Contact Length of 0.660" (16.76mm), while 10077239-108LF is 0.608" (15.44mm) and PHT-104-02-L-D is 0.552" (14.02mm). These variations may affect board layout and mating depth considerations in specific applications.

Q: Which substitute part is recommended for new designs?

A: For new designs requiring RoHS compliance and TE Connectivity series continuity, 5-103233-3 is the recommended choice. For applications requiring extended temperature range or higher current capacity, cross-manufacturer alternatives (10077239-108LF or PHT-104-02-L-D) should be evaluated based on specific design requirements.

Q: Are all substitute parts rated for the same operating temperature range?

A: No. The 103233-3, 5-103233-3, and PHT-104-02-L-D operate from -55°C ~ 125°C. The 10077239-108LF operates across a wider range of -65°C ~ 130°C. Application temperature requirements should be verified before part selection.

Q: What is the significance of the Last Time Buy status for 103233-3?

A: Last Time Buy status indicates that the manufacturer has discontinued production of this part. Existing inventory is available for purchase, but no future production is planned. Transition to an active substitute part is necessary for long-term supply chain continuity.
