Substitute Part Grouping Explanation

Substitution of the Molex 0705630039 is determined by the following critical parameters:

Connector Type & Contact Configuration: Header with male pins
Position Count & Row Configuration: 5 positions, single row
Pitch Specification: 0.100" (2.54mm) mating pitch
Mounting & Termination: Through-hole solder termination
Shrouding Design: Shrouded 4-wall construction
Compliance & Certifications: ROHS3 compliance and UL94 V-0 flammability rating

The substitute part Molex 1719710005 maintains these core functional parameters while offering active product status and enhanced specifications. Both parts share identical pitch, position count, mounting method, and shrouding configuration, establishing direct substitution compatibility at the functional level.

Engineering Selection Recommendations

The Molex 1719710005 is the manufacturer-recommended substitute for the obsolete Molex 0705630039. Both parts maintain identical core specifications for pitch, position count, mounting configuration, and shrouding design, ensuring mechanical and electrical compatibility in board-to-cable/wire applications.

The substitute part offers the following advantages:

Active Product Status: The 1719710005 is an active product with full manufacturing support and availability, eliminating supply chain risk associated with obsolete components.
Enhanced Material Specifications: Liquid Crystal Polymer (LCP) insulation provides improved thermal and chemical resistance compared to glass-filled thermoplastic.
Defined Operating Parameters: The substitute includes specified operating temperature range (-40°C to 105°C), current rating (3A), and voltage rating (250V), enabling precise application verification.
Compliance Continuity: Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification.

Minor differences in contact material (brass vs. phosphor bronze) and contact shape (circular vs. square) do not affect functional substitution for standard board-to-cable/wire interconnect applications.

Frequently Asked Questions (FAQ)

Q: Are the 0705630039 and 1719710005 mechanically interchangeable?

A: Yes. Both connectors share identical pitch (0.100"), position count (5), row configuration (single row), mounting type (through-hole), and shrouding design (4-wall). They are mechanically interchangeable in board-to-cable/wire applications.

Q: What are the key differences between these parts?

A: The primary differences are product status (obsolete vs. active), insulation material (thermoplastic glass-filled vs. LCP), contact material (phosphor bronze vs. brass), and contact shape (square vs. circular). The substitute includes defined operating temperature, current, and voltage ratings not specified for the original part.

Q: Can I use the 1719710005 as a direct replacement in existing designs?

A: Yes. The substitute maintains all critical functional parameters. Verify that the defined operating specifications (3A current, 250V voltage, -40°C to 105°C temperature range) meet or exceed your application requirements.

Q: Does the change in insulation material affect performance?

A: Liquid Crystal Polymer (LCP) insulation in the substitute provides enhanced thermal stability and chemical resistance compared to glass-filled thermoplastic. This represents an improvement for most applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the 0705630039 and 1719710005 are ROHS3 compliant and carry UL94 V-0 flammability certification.

Q: What is the packaging difference?

A: The original part number does not specify packaging. The substitute (1719710005) is supplied in tube packaging.
