Parameter Comparison

Engineering Selection Recommendations

The Molex 1719710105 is the direct manufacturer-recommended substitute for the obsolete 0705630004. Both connectors maintain identical mechanical and electrical interface specifications across all critical mating parameters, ensuring form-fit-function compatibility.

The 1719710105 offers the advantage of active product status with established supply chain availability. Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, meeting equivalent regulatory requirements. The substitute features an enhanced insulation material composition (Liquid Crystal Polymer versus Thermoplastic, Glass Filled) and includes a polarizing key feature for improved assembly guidance.

Minor material differences exist in contact construction: the substitute uses brass contacts with circular geometry compared to the original phosphor bronze square contacts. These material and geometry variations remain within acceptable substitution parameters for this connector category and do not compromise electrical or mechanical performance in standard board-to-cable/wire applications.

Frequently Asked Questions (FAQ)

Q: Are the 0705630004 and 1719710105 mechanically interchangeable?

A: Yes. Both connectors share identical pitch (0.100" / 2.54mm), position count (5), row configuration (1), mounting type (through hole), and shrouding design (4-wall). Mating contact dimensions and insulation heights are identical, ensuring direct mechanical compatibility.

Q: What are the key differences between these parts?

A: The primary differences are product status (obsolete versus active), insulation material composition (thermoplastic glass-filled versus liquid crystal polymer), contact material (phosphor bronze versus brass), and contact geometry (square versus circular). The substitute includes a polarizing key feature. These variations do not affect functional compatibility in standard applications.

Q: Can I use the 1719710105 in existing designs specified for the 0705630004?

A: Yes. The substitute maintains all critical interface parameters required for board-to-cable/wire connector applications. The identical pitch, position count, mounting type, and contact finish specifications ensure compatibility with existing mating connectors and PCB layouts.

Q: What is the significance of the polarizing key feature on the 1719710105?

A: The polarizing key provides mechanical guidance during assembly to prevent incorrect connector orientation. This feature enhances manufacturing reliability and does not interfere with designs using the original non-keyed connector.

Q: Are both parts RoHS compliant?

A: Yes. Both the 0705630004 and 1719710105 are ROHS3 compliant and carry UL94 V-0 flammability certification, meeting equivalent regulatory and safety standards.

Q: What packaging is available for the substitute part?

A: The 1719710105 is supplied in tube packaging with 6750 pieces in current stock inventory.
