Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment of the following critical parameters:

• Position count and pitch: All substitute parts must have 8 positions at 0.200" (5.08mm) spacing
• Connector type and orientation: Female socket plugs with 180° wire entry for free-hanging in-line mounting
• Electrical ratings: UL current rating of 15 A and UL voltage rating of 300 V
• Termination method: Screw-based connection with M3 screw size
• Physical compatibility: Insulation height of 0.591" (15.00mm) and matching housing material (Polyamide/Nylon)
• Regulatory compliance: ROHS3 compliance and MSL 1 rating

The identified substitute parts (Phoenix Contact 1757077 and 5441809) meet these core electrical and mechanical requirements, enabling functional equivalence in applications designed for the Molex 0395305708.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and ROHS3 compliance, confirming ongoing manufacturing support and regulatory alignment.

Phoenix Contact 1757077 aligns most closely with the Molex 0395305708 across specified parameters. Both parts feature M3 screw sizing, matching torque specifications (0.5-0.6 Nm), and identical insulation height. The 1757077 extends wire gauge compatibility to 12-30 AWG and provides higher IEC current rating (12 A) and voltage rating (630 V), offering enhanced electrical margin. Contact mating finish differs (tin versus gold), which does not affect UL electrical ratings but may influence contact resistance characteristics in specific applications.

Phoenix Contact 5441809 meets core electrical and mechanical requirements but presents parameter variations. Screw size and torque specifications are not provided, limiting direct mechanical equivalence confirmation. Wire strip length (7mm versus 5mm) and housing material specifications are not detailed. The black color designation differs from the green standard. This part remains functionally equivalent for applications where the specified parameter variations are acceptable.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1757077 directly replace Molex 0395305708 in existing designs?

A: Yes. Both parts share identical pitch (5.08mm), position count (8), wire entry orientation (180°), mounting type (free-hanging in-line), and UL electrical ratings (15 A, 300 V). M3 screw sizing and torque specifications are compatible. The extended wire gauge range (12-30 AWG versus 12-26 AWG) provides additional flexibility without reducing compatibility.

Q: What is the significance of the contact mating finish difference (gold versus tin)?

A: Contact mating finish affects contact resistance and corrosion resistance characteristics. Gold plating provides superior corrosion resistance and lower contact resistance, particularly in low-signal applications. Tin plating is suitable for standard industrial applications with adequate contact pressure. Both finishes meet UL electrical ratings specified for this product category.

Q: Is Phoenix Contact 5441809 suitable as a substitute?

A: Phoenix Contact 5441809 meets core electrical and mechanical requirements (8 positions, 5.08mm pitch, 180° entry, 15 A UL rating, 300 V UL rating). However, unspecified screw size and torque parameters, along with undocumented housing material, limit direct mechanical equivalence confirmation. This part is functionally equivalent for applications where these parameter variations are acceptable.

Q: How do wire gauge ranges affect substitution?

A: The Molex 0395305708 supports 12-26 AWG wire. Both Phoenix Contact substitutes support 12-30 AWG, extending compatibility to smaller gauge wires. This expanded range does not reduce compatibility with the original specification and may accommodate additional application requirements.

Q: Are there inventory considerations for part selection?

A: Molex 0395305708 has 656 units in stock. Phoenix Contact 1757077 has 1405 units, and Phoenix Contact 5441809 has 1127 units. Substitute parts offer higher inventory availability for applications requiring immediate procurement.

Q: What compliance certifications apply to all three parts?

A: All parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings. Both Phoenix Contact parts maintain REACH compliance status (1757077: Unaffected; 5441809: Affected). All parts share identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications.
