Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1-104433-2 is determined by strict alignment of the following critical parameters:

Position and Pitch Compatibility: The substitute connector must provide 24 positions arranged in 2 rows with 0.100" (2.54mm) mating pitch and 0.100" (2.54mm) row spacing to ensure mechanical interchangeability with mating connectors and printed circuit board layouts.

Contact Configuration: Male pin contact type is required to maintain electrical continuity with existing female receptacle connectors in the application.

Mounting and Termination: Through-hole mounting type is mandatory for compatibility with standard PCB assembly processes. Solder termination capability is required for permanent board attachment.

Electrical Performance: The substitute must support the application's electrical requirements, including current and voltage ratings appropriate for the circuit design.

Fastening Mechanism: Push-pull fastening type ensures mechanical retention and disconnection capability consistent with the original design.

Environmental Specifications: Operating temperature range and moisture sensitivity level must accommodate the application's environmental conditions.

The Samtec BBD-112-T-B satisfies these substitution criteria through equivalent position count, pitch spacing, contact type, mounting method, and fastening mechanism.

Parameter Comparison

Engineering Selection Recommendations

Obsolescence Mitigation: The TE Connectivity 1-104433-2 is classified as obsolete. The Samtec BBD-112-T-B is an active product with confirmed inventory availability, providing long-term supply continuity for production and design requirements.

Regulatory Compliance: The Samtec BBD-112-T-B is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components in most jurisdictions. The original TE Connectivity part is RoHS non-compliant and REACH affected, presenting compliance constraints for new applications.

Mechanical Compatibility: Both connectors share identical position count (24), row configuration (2 rows), mating pitch (0.100"), and row spacing (0.100"), ensuring direct mechanical interchangeability with existing mating connectors and PCB footprints.

Electrical Equivalence: Both connectors utilize male pin contacts with push-pull fastening and through-hole solder termination. The Samtec part operates across a wider temperature range (-55°C to 125°C versus -65°C to 105°C), providing enhanced thermal performance for extended operating environments.

Contact Finish Differences: The Samtec BBD-112-T-B features tin-plated mating contacts and nickel-plated posts, compared to gold-plated mating contacts and tin-lead posts on the original part. These finishes are functionally equivalent for standard board-to-board applications within the specified electrical parameters.

Material Composition: The Samtec part utilizes polyester glass-filled insulation material, providing improved mechanical strength and thermal stability compared to the thermoplastic insulation of the original connector.

Frequently Asked Questions (FAQ)

Q: Can the Samtec BBD-112-T-B directly replace the TE Connectivity 1-104433-2 in existing designs?

A: Yes. Both connectors share identical position count, row configuration, pitch spacing, contact type, mounting method, and fastening mechanism.
