Molex 0395300708 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Molex 0395300708 is an 8-position terminal block plug with female sockets, 0.200" (5.08mm) pitch, designed for 180° free-hanging in-line applications. This component is part of the Eurostyle ESE 39530 series and is currently in active production status with 732 units in stock. Terminal block plugs of this specification are essential for modular electrical interconnection systems requiring screw-based termination and standardized pitch spacing. Substitute parts may be required due to supply constraints, design standardization across manufacturing facilities, or specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0395300708 is determined by strict alignment of the following critical parameters:

• Position Count & Pitch: Must be 8 positions at 0.200" (5.08mm) spacing to ensure mechanical and electrical compatibility with mating connectors
• Connector Type: Must be a plug with female sockets to maintain proper mating orientation
• Mounting Configuration: Must support 180° free-hanging in-line installation
• Termination Method: Must utilize screw-based termination for consistent clamping force and reliability
• Electrical Ratings: Must meet or exceed UL ratings of 15 A at 300 V to ensure safe operation in the intended application
• Wire Gauge Compatibility: Must accommodate 12-26 AWG wire range or broader
• Insulation Height: Must match 0.591" (15.00mm) for proper board-level clearance and mechanical fit
• Regulatory Compliance: Must maintain ROHS3 compliance and equivalent certifications

The Phoenix Contact 5441809 qualifies as a direct substitute based on these parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0395300708 and Phoenix Contact 5441809 are active production components with ROHS3 compliance and equivalent regulatory certifications (EAR99, HTSUS 8536.90.4000). Selection between these parts should be based on:

• Supply Availability: The Phoenix Contact 5441809 currently has 1127 units in stock compared to 732 units for the Molex part, providing greater availability for high-volume requirements
• Wire Gauge Accommodation: The Phoenix Contact part supports 12-30 AWG, providing compatibility with a broader wire gauge range than the Molex specification of 12-26 AWG
• Electrical Performance: Both parts meet identical UL electrical ratings (15 A, 300 V) and are suitable for equivalent applications
• Mechanical Compatibility: Identical pitch, position count, mounting configuration, and insulation height ensure direct mechanical interchangeability with existing mating connectors and PCB layouts
• Regulatory Status: Both parts maintain equivalent compliance certifications, ensuring suitability for regulated applications

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 5441809 be used as a direct replacement for the Molex 0395300708 in existing assemblies?

A: Yes. Both parts share identical mechanical dimensions (8 positions, 0.200" pitch, 0.591" insulation height), mounting configuration (180° free-hanging in-line), and electrical ratings (15 A UL, 300 V UL). The parts are mechanically and electrically interchangeable with existing mating connectors and circuit board layouts.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Termination style specification—Molex uses "Screw - Rising Cage Clamp" while Phoenix Contact specifies "Screw"; (2) Wire gauge range—Phoenix Contact supports 12-30 AWG versus Molex 12-26 AWG; (3) Contact mating finish—Molex uses gold while Phoenix Contact uses tin; (4) Torque specification—Molex specifies 0.56 Nm (5.0 Lb-In) while Phoenix Contact specifies 0.4-0.5 Nm (4.6-4.4 Lb-In); (5) Wire strip length—Molex requires 5mm while Phoenix Contact requires 7mm.

Q: Are there any wire gauge limitations when substituting the Phoenix Contact part?

A: The Phoenix Contact 5441809 accommodates 12-30 AWG wire, which encompasses the Molex specification of 12-26 AWG. Applications using wire gauges within the 12-26 AWG range are fully compatible with both parts. Applications requiring 27-30 AWG wire can only use the Phoenix Contact part.

Q: Do both parts have the same regulatory compliance status?

A: Yes. Both the Molex 0395300708 and Phoenix Contact 5441809 are ROHS3 compliant, carry MSL rating 1 (Unlimited), and share identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications.

Q: What is the difference in contact mating finish between these parts?

A: The Molex part uses gold plating on the contact mating surfaces, while the Phoenix Contact part uses tin plating. Both finishes are suitable for screw-terminal applications; gold provides enhanced corrosion resistance in high-humidity environments, while tin offers cost efficiency in standard industrial applications.

Q: Are there torque specification differences that affect installation?

A: Yes. The Molex part specifies a screw torque of 0.56 Nm (5.0 Lb-In), while the Phoenix Contact part specifies 0.4-0.5 Nm (4.6-4.4 Lb-In). When substituting, use the torque specification provided by the substitute part manufacturer to ensure proper clamping force and prevent wire damage or connection failure.
