Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 7-146308-0 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Substitution Criteria:

• Connector Type: Header, Breakaway
• Contact Type: Male Pin
• Number of Positions: 40
• Number of Rows: 2
• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Fastening Type: Push-Pull
• Shrouding: Unshrouded
• Style: Board to Board or Cable
• Material Flammability Rating: UL94 V-0

The Molex 0901220140 connector satisfies all primary substitution criteria, enabling direct functional replacement in applications requiring 40-position, 2-row, right-angle header connectors with 2.54mm pitch spacing and push-pull fastening. Both parts maintain identical position count, row configuration, pitch specifications, and mounting methodology, establishing compatibility at the mechanical and electrical interface level.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 7-146308-0 Selection Criteria:

• Primary choice when gold-plated mating contacts are required for enhanced corrosion resistance
• Specified 3A current rating provides explicit electrical performance documentation
• RoHS Compliant status suitable for applications with RoHS Phase 1 requirements
• Thermoplastic insulation material selection for specific thermal or chemical compatibility needs

Molex 0901220140 Selection Criteria:

• Qualified substitute when tin-plated mating contacts meet application requirements
• ROHS3 Compliant status addresses updated RoHS Directive requirements
• Brass contact material provides alternative electrical and mechanical properties
• Polyester insulation material selection for specific environmental or performance requirements
• Longer mating contact length (0.266" vs 0.230") accommodates deeper mating depth applications

Both parts maintain Active product status with full RoHS compliance and unlimited moisture sensitivity rating (MSL 1), ensuring long-term availability and environmental regulation adherence. Selection between these parts depends on specific contact finish requirements, insulation material compatibility, and mating contact length specifications for the target application.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0901220140 directly replace the TE Connectivity 7-146308-0 in existing designs?

A: The Molex 0901220140 provides functional compatibility for applications where the connector interface specifications (40 positions, 2 rows, 2.54mm pitch, right-angle through-hole mounting, push-pull fastening) are the primary design requirements. However, design review is necessary to evaluate differences in contact finish (tin vs. gold), contact materials (brass vs. copper alloy), and insulation materials (polyester vs. thermoplastic) against application-specific performance criteria.

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

A: The primary dimensional variations are contact length specifications. The Molex 0901220140 features a longer mating contact length (0.266" vs. 0.230") and slightly shorter post contact length (0.114" vs. 0.120"). Insulation height differs minimally (0.242" vs. 0.238"). These variations may affect mating depth and board layout considerations in space-constrained applications.

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

A: The TE Connectivity 7-146308-0 uses gold-plated mating contacts (30.0µin thickness), providing superior corrosion resistance and lower contact resistance in high-reliability applications. The Molex 0901220140 uses tin-plated mating contacts (157.5µin thickness), suitable for general-purpose and automotive applications where gold plating is not required. Contact finish selection depends on environmental exposure, signal integrity requirements, and cost considerations.

Q: Are both connectors suitable for automotive applications?

A: The Molex 0901220140 explicitly lists automotive applications in its specification. The TE Connectivity 7-146308-0 does not specify automotive applications in the provided data. Automotive application suitability requires evaluation against specific automotive qualification standards and environmental requirements beyond the provided parameter set.

Q: What is the significance of the different insulation materials?

A: The TE Connectivity 7-146308-0 uses thermoplastic, glass-filled insulation, while the Molex 0901220140 uses polyester, glass-filled insulation. Both materials achieve UL94 V-0 flammability rating. Material selection affects thermal stability, chemical resistance, and mechanical properties. Application-specific environmental conditions determine which insulation material is appropriate.

Q: Do both connectors meet current RoHS requirements?

A: Yes. The TE Connectivity 7-146308-0 is RoHS Compliant (Phase 1), and the Molex 0901220140 is ROHS3 Compliant (updated directive). Both parts satisfy RoHS environmental compliance requirements. ROHS3 compliance indicates adherence to the most current RoHS Directive amendments.

Q: What is the current rating difference between these parts?

A: The TE Connectivity 7-146308-0 specifies a 3A current rating per contact. The Molex 0901220140 does not provide a current rating specification in the available data. Applications requiring explicit current rating documentation should reference the TE Connectivity part or obtain detailed current specifications from Molex technical documentation.

Q: Are these connectors available in equivalent configurations with different position counts?

A: The provided data addresses only the 40-position, 2-row configuration. Both manufacturers offer connector families with alternative position counts and row configurations. Specific alternative configurations require consultation of complete product line documentation from each manufacturer.
