Molex 0395105504 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Molex 0395105504 is a 4-position terminal block plug with female sockets, 0.150" (3.81mm) pitch, designed for 180° free-hanging in-line applications. This component is classified as Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling direct replacement in applications where the main part is unavailable or inventory constraints require alternative sourcing.

Substitute Part Grouping Explanation

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

Electrical Compatibility: Voltage rating (UL) ≥ 300 V and current rating (UL) ≥ 8 A
Mechanical Compatibility: 4-position configuration, 0.150" (3.81mm) pitch, female socket type, 180° wire entry, free-hanging mounting
Environmental Compliance: UL94 V-0 flammability rating, operating temperature range that encompasses or exceeds -40°C ~ 115°C
Physical Dimensions: Insulation height 0.437" (11.10mm), compatible wire gauge range that includes 16-30 AWG

The identified substitute parts (Weidmüller 1792880000 and Phoenix Contact 1803594) meet all critical electrical and mechanical parameters required for direct replacement in the Molex 0395105504 application.

Engineering Selection Recommendations

All three components—Molex 0395105504, Weidmüller 1792880000, and Phoenix Contact 1803594—maintain Active product status and meet UL94 V-0 flammability requirements. The Molex and Phoenix Contact parts share identical termination methodology (Screw - Rising Cage Clamp), while the Weidmüller variant employs Screw - Clamping Yoke (Tension Sleeve) termination. Both termination styles are functionally equivalent for this application class.

The Weidmüller 1792880000 provides enhanced current capacity (10 A UL vs. 8 A UL) and extended operating temperature range (-50°C ~ 120°C vs. -40°C ~ 115°C), offering additional design margin. The Phoenix Contact 1803594 supports an expanded wire gauge range (14-30 AWG vs. 16-30 AWG), accommodating larger conductor cross-sections.

Selection should be based on inventory availability, supply chain requirements, and specific application constraints. All three parts satisfy the core electrical and mechanical specifications for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can Weidmüller 1792880000 replace Molex 0395105504 in existing designs?

A: Yes. Both components share identical pitch (0.150"), position count (4), socket type (female), wire entry angle (180°), mounting configuration (free-hanging), voltage rating (300 V UL), and flammability classification (UL94 V-0). The Weidmüller part exceeds the current specification (10 A vs. 8 A) and operating temperature range, making it a direct electrical and mechanical substitute.

Q: What is the difference between Rising Cage Clamp and Clamping Yoke termination?

A: Both termination styles secure wire conductors via screw-driven clamping mechanisms. Rising Cage Clamp (Molex, Phoenix Contact) uses a spring-loaded cage that rises as the screw tightens. Clamping Yoke (Weidmüller) employs a tension sleeve mechanism. Both methods provide equivalent electrical contact and mechanical retention for this application class.

Q: Does Phoenix Contact 1803594 support the full wire gauge range of Molex 0395105504?

A: Phoenix Contact 1803594 supports 14-30 AWG, which encompasses the Molex specification of 16-30 AWG. The Phoenix Contact part accommodates additional smaller gauge conductors (14-15 AWG) beyond the original requirement.

Q: Are all three parts RoHS compliant?

A: Yes. Molex 0395105504 and Phoenix Contact 1803594 are ROHS3 compliant. Weidmüller 1792880000 is RoHS compliant. All three meet RoHS requirements for lead-free construction.

Q: What is the impact of different wire strip lengths across these parts?

A: Molex specifies 6.5mm wire strip length; Weidmüller and Phoenix Contact specify 7mm. This 0.5mm difference is within standard manufacturing tolerance and does not affect functional compatibility or mating performance in typical applications.
