Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 350587-2 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Number of positions: 12
• Number of rows: 3
• Pitch spacing (mating): 0.250" (6.35mm)
• Row spacing (mating): 0.250" (6.35mm)
• Mounting type: Through hole
• Termination method: Solder
• Connector style: Board to cable/wire
• Fastening type: Locking ramp
• Contact shape: Circular
• Insulation height: 0.550" (13.97mm)

The Molex 0010845121 satisfies all critical mechanical and electrical parameters required for functional equivalence. While the main part features male pin contacts with gold finish and the substitute features female socket contacts with tin finish, both components maintain identical pitch spacing, row configuration, mounting methodology, and physical envelope dimensions. The contact type difference (male versus female) represents a complementary pairing relationship rather than a direct pin-for-pin substitution, suitable for mating applications.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 350587-2 is classified as obsolete, requiring transition to active equivalent components for new procurement. The Molex 0010845121 provides functional equivalence based on matching mechanical parameters and connector geometry.

Compliance Considerations:

The Molex 0010845121 holds ROHS3 compliance status, whereas the TE Connectivity 350587-2 is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the Molex substitute satisfies current environmental compliance mandates. The Molex component is rated for -55°C to 105°C operating temperature and 600V voltage rating, providing defined performance boundaries absent from the obsolete TE Connectivity specification.

Contact Finish Differences:

The TE Connectivity 350587-2 features gold-plated mating contacts (30.0µin thickness), while the Molex 0010845121 utilizes tin-plated mating contacts (137.8µin thickness). Both employ tin-plated posts. Gold plating provides enhanced corrosion resistance and lower contact resistance; tin plating offers cost efficiency and adequate performance for general-purpose applications. Selection between these finishes depends on application-specific requirements for contact reliability and environmental exposure.

Insulation Material Variation:

The TE Connectivity component uses polyamide (PA) nylon insulation, while the Molex substitute employs polybutylene terephthalate (PBT). PBT offers superior dimensional stability, chemical resistance, and flame rating (UL94 V-0 versus V-2), making it suitable for industrial and automotive applications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0010845121 directly replace the TE Connectivity 350587-2 in existing designs?

A: The Molex 0010845121 provides mechanical and electrical equivalence in terms of pitch spacing, row configuration, mounting type, and physical envelope. However, the contact type differs: the TE Connectivity part features male pins while the Molex part features female sockets. Direct replacement requires that the mating connector be compatible with the opposite contact gender. Both components maintain identical 0.250" (6.35mm) pitch and 3-row configuration, ensuring proper alignment and mating.

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

A: Primary differences include: (1) Contact type: male pin versus female socket; (2) Contact finish: gold-plated (TE) versus tin-plated (Molex); (3) Insulation material: polyamide nylon (TE) versus PBT (Molex); (4) Product status: obsolete (TE) versus active (Molex); (5) RoHS compliance: non-compliant (TE) versus ROHS3 compliant (Molex); (6) Operating temperature specification: unspecified (TE) versus -55°C to 105°C (Molex); (7) Voltage rating: unspecified (TE) versus 600V (Molex).

Q: Are there packaging differences between these parts?

A: The TE Connectivity 350587-2 packaging specification is not provided in the technical data. The Molex 0010845121 is supplied in bulk packaging. Packaging configuration may affect procurement quantities and handling procedures; contact the supplier for specific packaging requirements.

Q: Which connector should be selected for new designs?

A: The Molex 0010845121 is the appropriate selection for new designs. It maintains active product status, provides ROHS3 compliance, includes defined operating temperature and voltage ratings, and is currently available in production quantities. The TE Connectivity 350587-2 is obsolete and should not be specified for new applications.

Q: Does the contact finish difference affect electrical performance?

A: Both gold and tin finishes provide adequate electrical conductivity for general-purpose applications. Gold plating offers superior corrosion resistance and lower contact resistance, beneficial in high-reliability or corrosive environments. Tin plating is suitable for standard industrial applications with controlled environmental conditions. The choice depends on application-specific requirements for contact longevity and performance under environmental stress.

Q: What is the significance of the insulation material difference?

A: Polyamide (PA) nylon and polybutylene terephthalate (PBT) are both suitable insulation materials for connector applications. PBT provides superior dimensional stability across temperature ranges, enhanced chemical resistance, and achieves higher flame rating (UL94 V-0 versus V-2). For applications requiring higher temperature stability or exposure to chemical environments, PBT insulation offers performance advantages.
