Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1-284514-7 is determined by strict equivalence across the following critical parameters:

Position and Pitch Compatibility: The substitute part must maintain 17 positions with 0.138" (3.50mm) pitch spacing to ensure mechanical and electrical compatibility with existing PCB layouts and mating connectors.

Shrouding and Orientation: The four-sided shrouded design with vertical orientation is mandatory for proper mechanical fit and polarization within the application.

Electrical Ratings: The substitute must support the required voltage (300 V UL) and current (11 A UL minimum) specifications. Deviations in current capacity below the original specification indicate reduced electrical capability.

Termination and Mounting: Solder termination and through-hole mounting type must be preserved to maintain assembly compatibility.

Material and Thermal Properties: Housing material (Polyamide PA66/Nylon 6/6) and flammability rating (UL94 V-0) ensure consistent mechanical and safety performance across temperature ranges.

The Molex 0395011017 satisfies these core substitution criteria while maintaining functional equivalence for the terminal block header category.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: The Molex 0395011017 (Eurostyle ESE 39501 series) serves as the functional equivalent for the obsolete TE Connectivity 1-284514-7. Both components share identical position count, pitch, shrouding configuration, and mounting orientation, ensuring direct mechanical compatibility with existing PCB designs and mating connectors.

Compliance Considerations: The Molex substitute carries active product status and ROHS3 compliance, providing advantages for new designs and systems subject to regulatory requirements. The TE Connectivity original part carries no RoHS designation, reflecting its obsolete classification.

Electrical Performance Variance: The Molex 0395011017 operates at a reduced UL current rating of 8 A compared to the original 11 A specification. Applications requiring the full 11 A capacity must evaluate whether the 8 A rating satisfies circuit requirements. The voltage rating (300 V UL) remains equivalent across both parts.

Thermal Operating Range: The Molex substitute operates to a maximum of 105°C, compared to 110°C for the original part. Applications operating near the upper thermal limit require assessment of this 5°C reduction.

Contact Material Difference: The TE Connectivity original uses phosphor bronze contacts, while the Molex substitute uses brass contacts. Both materials are tin-plated and suitable for solder termination applications.

Mechanical Fit: Insulation height measurements differ by 0.06mm (0.362" versus 0.360"), representing a negligible variance within standard manufacturing tolerances and does not affect functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0395011017 be used as a direct replacement for the TE Connectivity 1-284514-7 in existing assemblies?

A: Yes, the Molex 0395011017 provides direct mechanical and electrical compatibility for applications operating within its specified current rating of 8 A and maximum temperature of 105°C. The identical pitch (3.50mm), position count (17), shrouding configuration, and through-hole mounting ensure compatibility with existing PCB layouts and mating connectors.

Q: What is the significance of the current rating difference between the two parts?

A: The TE Connectivity original supports 11 A UL current, while the Molex substitute supports 8 A UL current. This 3 A reduction represents a 27% decrease in current capacity. Applications must verify that circuit current requirements do not exceed 8 A to ensure safe operation with the substitute part.

Q: Are there compatibility concerns related to the operating temperature range difference?

A: The Molex substitute operates to 105°C maximum, compared to 110°C for the original part. This 5°C reduction is significant only for applications operating continuously near or above 105°C. Standard industrial applications operating below 100°C experience no practical impact.

Q: How do the contact materials affect performance and reliability?

A: The TE Connectivity original uses phosphor bronze contacts, while the Molex substitute uses brass contacts. Both materials are tin-plated for solder termination and provide equivalent electrical performance and corrosion resistance in standard operating environments. Contact material selection does not affect functional compatibility.

Q: What packaging considerations apply to the Molex substitute?

A: The Molex 0395011017 is supplied in bulk packaging, compared to the original part's unspecified packaging. Bulk packaging is standard for terminal block headers and does not affect component performance or installation procedures.

Q: Does the Molex substitute meet current regulatory requirements?

A: Yes, the Molex 0395011017 carries ROHS3 compliance certification, making it suitable for applications subject to RoHS regulations. The original TE Connectivity part carries no RoHS designation due to its obsolete status.

Q: Are there any mechanical fit concerns related to the insulation height difference?

A: The insulation height difference of 0.06mm (0.362" versus 0.360") falls within standard manufacturing tolerances and does not affect mechanical fit or functional compatibility with standard PCB designs and mating connectors.
