Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1707434 is determined by strict alignment with the following critical parameters:

Electrical Compatibility: Current rating (minimum 8 A UL), voltage rating (minimum 300 V UL), and contact mating finish (tin)
Mechanical Compatibility: 3-position configuration, 0.150" (3.81mm) pitch, vertical orientation, male pins with 4-side shrouding, through-hole solder termination
Regulatory Compliance: UL94 V-0 flammability rating, ROHS3 compliance, and EAR99 export classification
Physical Dimensions: Insulation height within 0.360" to 0.362" (9.14mm to 9.20mm) range

All identified substitute parts meet or exceed these parameters. Variations in housing material (Polyamide PA66 vs. Liquid Crystal Polymer), contact material composition, and operating temperature ranges do not affect functional substitution within the specified electrical and mechanical envelope.

Engineering Selection Recommendations

All identified substitute parts maintain active product status and full ROHS3 compliance, ensuring long-term availability and regulatory alignment. The Molex 0395111003 and 0395116003 parts are functionally equivalent at the 8 A UL current rating, with the primary distinction being housing color (black vs. green). The Würth Elektronik 691321300003 and Amphenol Anytek OQ0332500000G parts provide enhanced current capacity at 10 A UL, offering design margin for applications approaching the 8 A specification limit. All parts maintain identical pitch, position count, shrouding configuration, and solder termination compatibility. Selection among substitutes should be based on supply availability, lead time requirements, and any application-specific color coding or material preference constraints.

Frequently Asked Questions (FAQ)

Q: Can Molex 0395111003 directly replace Phoenix Contact 1707434? A: Yes. Both parts share identical electrical ratings (8 A UL, 300 V UL), mechanical configuration (3-position, 0.150" pitch, vertical male pins, 4-side shrouded), solder termination, and UL94 V-0 flammability rating. Housing material differs (Polyamide PA66 vs. Liquid Crystal Polymer), but this does not affect functional compatibility within the specified electrical envelope.

Q: What is the difference between Molex 0395111003 and 0395116003? A: Both parts are electrically and mechanically identical. The primary difference is housing color: 0395111003 is black, while 0395116003 is green. Both maintain 8 A UL current rating and 300 V UL voltage rating.

Q: Can I use Würth Elektronik 691321300003 in place of Phoenix Contact 1707434? A: Yes. The Würth part exceeds the minimum electrical requirements with 10 A UL current capacity versus 8 A, while maintaining all mechanical and regulatory specifications. Insulation height is identical at 0.362" (9.20mm).

Q: Are there any compliance differences between these substitute parts? A: All parts are ROHS3 compliant and carry UL94 V-0 flammability rating. The Würth Elektronik part is REACH Affected, while others are REACH Unaffected. This distinction does not affect electrical or mechanical substitution eligibility.

Q: What is the maximum operating temperature range across all parts? A: Phoenix Contact 1707434 does not specify operating temperature. Molex parts operate -40°C to 105°C, Würth Elektronik operates -40°C to 105°C, and Amphenol Anytek operates -40°C to 115°C. All exceed typical industrial control system requirements.

Q: Can I mix these parts in the same assembly? A: Yes. All parts maintain identical pitch, position count, and solder termination compatibility, enabling interchangeability within the same PCB layout and connector interface.
