TE Connectivity 1-104432-2 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-104432-2 is a vertical rectangular connector header manufactured under the AMPMODU Mod II series. This through-hole component features 24 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing, designed for board-to-board or cable interconnection applications. The connector utilizes male pin contacts with gold-plated mating surfaces and tin-lead plated posts, supporting 3A current at 30VAC with an operating temperature range of -65°C to 105°C.

The 1-104432-2 is classified as obsolete product status. Locating equivalent substitute components becomes necessary for new designs, production continuity, and long-term supply chain management. Active alternative connectors with compatible electrical and mechanical specifications are available to fulfill the same functional requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the TE Connectivity 1-104432-2 is determined by alignment of the following critical parameters:

Primary Matching Criteria:

• Number of positions: 24
• Number of rows: 2
• Pitch spacing (mating): 0.100" (2.54mm)
• Row spacing (mating): 0.100" (2.54mm)
• Contact type: Male Pin
• Mounting type: Through Hole
• Connector style: Board to Board

Secondary Compatibility Factors:

• Shrouding configuration: Unshrouded
• Fastening type: Push-Pull
• Termination method: Solder capability
• Operating temperature range overlap
• Voltage and current rating sufficiency

The Samtec Inc. BBD-112-T-B satisfies all primary matching criteria and maintains compatibility across secondary factors. Both connectors feature identical position counts, row configurations, and pitch specifications. Both support through-hole mounting with push-pull fastening and solder termination. The BBD-112-T-B operates across an extended temperature range (-55°C to 125°C) that encompasses the original part's operating window.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The TE Connectivity 1-104432-2 carries obsolete product status, indicating discontinued manufacturing and limited long-term availability. The Samtec BBD-112-T-B maintains active product status with current manufacturing support and established supply chain availability.

Compliance and Regulatory Status: The BBD-112-T-B provides ROHS3 compliance, addressing modern regulatory requirements for new designs and production environments. The original 1-104432-2 is RoHS non-compliant and REACH-affected, presenting potential restrictions in certain jurisdictions and applications.

Electrical and Mechanical Compatibility: Both connectors satisfy the core functional requirements: 24-position, 2-row configuration with 0.100" (2.54mm) pitch spacing, through-hole mounting, male pin contacts, and push-pull fastening. The BBD-112-T-B operates across an extended temperature range (-55°C to 125°C) that fully encompasses the original part's operating window (-65°C to 105°C).

Physical Dimensional Differences: The BBD-112-T-B exhibits increased insulation height (0.335" versus 0.090") and slightly greater overall contact length (0.585" versus 0.533"). These dimensional variations require verification against specific PCB layout and mechanical clearance requirements in the target application.

Contact Finish Differences: The original part features gold-plated mating contacts with tin-lead posts. The substitute utilizes tin-plated mating contacts with nickel-plated posts. These material differences may affect contact resistance characteristics and long-term reliability in specific environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can the Samtec BBD-112-T-B directly replace the TE Connectivity 1-104432-2 in existing designs?

A: The BBD-112-T-B matches all critical position, row, and pitch specifications required for functional compatibility. However, the increased insulation height (0.335" versus 0.090") and different contact finish materials require verification against specific PCB layout constraints and electrical performance requirements before implementation.

Q: What are the key differences between these two connectors?

A: Primary differences include product status (obsolete versus active), compliance certifications (RoHS non-compliant versus ROHS3 compliant), contact finish materials (gold/tin-lead versus tin/nickel), insulation material composition (thermoplastic versus polyester glass-filled), and physical dimensions (insulation height and overall contact length). Both connectors maintain identical position counts, row configurations, pitch spacing, and mounting methods.

Q: Are the electrical ratings equivalent between these parts?

A: The TE Connectivity 1-104432-2 specifies 3A current rating at 30VAC. The Samtec BBD-112-T-B does not provide published current and voltage ratings in the available specifications. Applications requiring specific electrical performance validation should obtain detailed electrical specifications from Samtec for the BBD-112-T-B.

Q: What is the significance of the different contact shapes (square versus circular)?

A: The original part features square-shaped contacts while the substitute uses circular contacts. This geometric difference affects contact engagement characteristics and mating force profiles. PCB pad design and connector receptacle compatibility must be verified to ensure proper contact engagement and electrical performance.

Q: Does the extended operating temperature range of the BBD-112-T-B provide additional capability?

A: The BBD-112-T-B operates from -55°C to 125°C, compared to the original part's -65°C to 105°C range. While the substitute's upper temperature limit extends 20°C higher, the lower temperature limit is 10°C higher. Applications requiring operation below -55°C would not be suitable for the BBD-112-T-B.

Q: What packaging considerations apply to the BBD-112-T-B?

A: The Samtec BBD-112-T-B is supplied in tube packaging with 992 pieces in stock. The original TE Connectivity part does not specify packaging format. Tube packaging affects handling, storage, and automated assembly compatibility compared to alternative packaging methods.

Q: Are there any regulatory or compliance advantages to using the BBD-112-T-B?

A: The BBD-112-T-B is ROHS3 compliant and REACH unaffected, providing compliance with modern regulatory requirements. The original 1-104432-2 is RoHS non-compliant and REACH-affected, which may restrict use in certain jurisdictions or applications with specific regulatory requirements.

Q: How do the contact finish materials affect connector performance?

A: The original part uses gold-plated mating surfaces with tin-lead posts, while the substitute uses tin-plated mating surfaces with nickel-plated posts. Gold plating typically provides superior corrosion resistance and lower contact resistance. Tin plating offers cost advantages but may exhibit higher contact resistance and oxidation susceptibility in certain environments. Application-specific environmental conditions should guide material selection.
