Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connectors is determined by compatibility across critical electrical and mechanical parameters. The primary criteria for establishing substitute relationships include:

Electrical Compatibility Parameters:

• Pitch spacing (0.100" / 2.54mm)
• Number of positions (4)
• Contact type (Male Pin)
• Fastening mechanism (Push-Pull)

Mechanical Compatibility Parameters:

• Mounting configuration (Through Hole, Right Angle)
• Connector style (Board to Board or Cable)
• Shrouding type (Unshrouded)
• Number of rows (1)

Environmental & Compliance Parameters:

• Material flammability rating (UL94 V-0)
• Moisture sensitivity level (1 - Unlimited)
• Product status (Active)

The Molex 0901210764 connector satisfies these core substitution criteria through matching pitch spacing, position count, contact type, mounting style, and environmental ratings. Variations in contact finish, contact material, and insulation material do not preclude substitution when electrical and mechanical interfaces remain compatible.

Engineering Selection Recommendations

TE Connectivity 104431-2 Selection Criteria: The TE Connectivity AMP Connectors 104431-2 is appropriate for applications requiring Tin-Lead contact finish and dual termination options (Press-Fit and Solder). This part maintains Active product status and is RoHS non-compliant. The connector supports operating temperatures from -65°C to 105°C with a 3A current rating at 30VAC. This part is suitable for legacy designs or applications where RoHS non-compliance is acceptable.

Molex 0901210764 Selection Criteria: The Molex 0901210764 connector is appropriate for applications requiring RoHS3 compliance and gold-plated mating contacts. This part maintains Active product status and is REACH Unaffected. The connector features solder-only termination and is designated for automotive and general-purpose applications. The gold contact finish provides enhanced corrosion resistance compared to tin-lead finishes. This part is suitable for new designs requiring regulatory compliance or enhanced environmental durability.

Substitution Applicability: Both connectors are electrically and mechanically compatible for standard board-to-board and cable interconnection applications. Selection between these parts depends on regulatory compliance requirements, contact finish specifications, and termination method preferences rather than functional capability differences.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0901210764 directly replace the TE Connectivity 104431-2 in existing designs?

A: The Molex 0901210764 provides electrical and mechanical compatibility through matching pitch spacing (0.100" / 2.54mm), position count (4), contact type (Male Pin), mounting style (Through Hole, Right Angle), and fastening mechanism (Push-Pull). Physical board layout compatibility requires verification of contact length variations: the TE Connectivity part features 0.318" (8.08mm) mating contact length versus 0.266" (6.75mm) for the Molex part. Insulation height differences (0.138" versus 0.142") are minimal and typically do not affect board-level compatibility.

Q: What are the key differences between these connectors?

A: Primary differences include contact finish (Tin-Lead versus Gold), contact material (Copper Alloy versus Brass), insulation material (Thermoplastic versus Polyester, Glass Filled), termination options (Press-Fit/Solder versus Solder only), and regulatory compliance status (RoHS non-compliant versus RoHS3 Compliant). These differences do not affect electrical interface compatibility but influence environmental performance, regulatory applicability, and manufacturing process requirements.

Q: Which connector should be selected for new product designs?

A: The Molex 0901210764 is appropriate for new designs requiring RoHS3 compliance and REACH compliance status. The TE Connectivity 104431-2 is appropriate for legacy designs or applications where RoHS non-compliance is acceptable and dual termination capability is required.

Q: Are there current or voltage rating differences between these connectors?

A: The TE Connectivity 104431-2 specifies 3A current rating at 30VAC. The Molex 0901210764 does not provide current or voltage ratings in the available specifications. Applications requiring specific electrical performance validation should reference manufacturer datasheets for detailed electrical characteristics.

Q: What is the significance of contact finish differences?

A: The TE Connectivity 104431-2 features Tin-Lead contact finish (100.0µin / 2.54µm thickness), while the Molex 0901210764 features Gold contact finish (15.0µin / 0.38µm thickness). Gold plating provides enhanced corrosion resistance and is preferred for automotive and harsh environmental applications. Tin-Lead finish is suitable for standard industrial applications with controlled environmental conditions.

Q: Can these connectors be used interchangeably in automotive applications?

A: The Molex 0901210764 is designated for automotive applications. The TE Connectivity 104431-2 does not specify automotive application suitability. For automotive applications, the Molex 0901210764 is the appropriate selection.

Q: What are the termination method differences?

A: The TE Connectivity 104431-2 supports both Press-Fit and Solder termination methods. The Molex 0901210764 supports Solder termination only. Applications requiring press-fit assembly capability must use the TE Connectivity part.
