Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0395205504 are qualified based on the following critical parameters that determine functional equivalence:

Core Matching Criteria:

• 4-position configuration with female sockets
• 5.00mm (0.197") pitch spacing
• 180° free-hanging in-line mounting orientation
• Screw-based termination with rising cage clamp mechanism
• UL94 V-0 flammability rating
• Compatible wire gauge range (12-30 AWG)
• 300 V UL voltage rating
• ROHS3 compliance

Identified Substitutes:

• Phoenix Contact 1756298 (COMBICON MSTB series)
• Phoenix Contact 5441184 (BCP series)

Both substitutes maintain the core electrical and mechanical specifications required for direct replacement in applications utilizing the Molex Eurostyle ESE 39520 series connector system.

Parameter Comparison

Engineering Selection Recommendations

Molex 0395205504 remains the primary specification when the original design calls for gold contact mating finish and the 18 A UL current rating. This part is active in production with full ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Phoenix Contact 1756298 (COMBICON MSTB series) is suitable as a substitute when the application can accommodate a 15 A UL current rating and tin contact finish. This part maintains the rising cage clamp termination style and is active in production with ROHS3 compliance and REACH unaffected status.

Phoenix Contact 5441184 (BCP series) is suitable as a substitute when the application can accommodate a 15 A UL current rating, tin contact finish, and standard screw termination without rising cage clamp. This part is active in production with ROHS3 compliance and REACH affected status.

All three parts share identical pitch spacing, position count, mounting orientation, wire gauge compatibility, voltage rating, and flammability rating. Selection between these options depends on current rating requirements, contact finish specifications, and regulatory compliance needs specific to the end application.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1756298 or 5441184 be used as direct replacements for the Molex 0395205504?

A: Both Phoenix Contact parts are functionally equivalent for applications requiring 4-position, 5mm pitch terminal block plugs with 180° free-hanging in-line mounting. However, the Molex part supports 18 A UL current, while both Phoenix Contact substitutes are rated for 15 A UL. Verify that your application current requirements do not exceed 15 A before substitution.

Q: What is the difference between Phoenix Contact 1756298 and 5441184?

A: Both parts share the same 4-position, 5mm pitch configuration and 15 A UL current rating. The primary difference is termination style: 1756298 uses screw with rising cage clamp, while 5441184 uses standard screw termination. Additionally, 5441184 has REACH affected status, whereas 1756298 is REACH unaffected.

Q: Are there differences in contact finish between these parts?

A: Yes. The Molex 0395205504 features gold contact mating finish, while both Phoenix Contact substitutes use tin finish. Gold finish provides superior corrosion resistance in certain environments; tin finish is standard for general industrial applications. Confirm contact finish requirements for your specific application.

Q: Do all three parts support the same wire gauge range?

A: All three parts accept 12-30 AWG wire. Phoenix Contact parts additionally specify 0.2-2.5mm² metric wire gauge range. Wire stripping length varies slightly: Molex requires 6.5mm, while Phoenix Contact parts require 7mm.

Q: What are the torque specifications for screw termination?

A: Molex 0395205504 specifies 0.56 Nm (5.0 Lb-In). Phoenix Contact 1756298 specifies 0.5-0.6 Nm (4.4-5.3 Lb-In), and 5441184 specifies 0.4-0.5 Nm (4.6-4.4 Lb-In). Ensure torque application remains within the specified range for each part to prevent wire damage or connection failure.

Q: Are all parts RoHS3 compliant?

A: Yes. All three parts are ROHS3 compliant. The Molex part has unlimited MSL (1), as do both Phoenix Contact substitutes. Both Phoenix Contact parts are classified as EAR99 for export control purposes, matching the Molex classification.
