Molex 0395932003 Terminal Block: Equivalent & Substitute Parts

Part Overview

The Molex 0395932003 is a 3-position wire-to-board terminal block with 5.00mm pitch, designed for horizontal mounting on PCBs through-hole connections. This component is classified as Active and maintains full RoHS3 compliance. Alternative equivalent parts are necessary when addressing supply chain constraints, specific application requirements for higher current ratings, or when alternative wire gauge compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0395932003 is determined by the following critical parameters:

• Position Count & Pitch: All substitutes must maintain 3 positions with pitch specifications of 0.197" (5.00mm) or 0.200" (5.08mm), as these dimensions define PCB footprint compatibility.
• Mating Orientation: Horizontal with board orientation is mandatory for direct substitution.
• Mounting Type: Through-hole mounting is required.
• Voltage & Current Ratings: Substitutes must meet or exceed 300 V voltage rating. Current rating may exceed the original 10 A specification.
• Wire Gauge Compatibility: Substitutes must accommodate wire gauges within or overlapping the 14-24 AWG range.
• Compliance: RoHS3 compliance is required for equivalent substitution.

The two identified substitutes—Phoenix Contact 1985933 and 1985959—meet these criteria while offering enhanced current capacity (20 A) and expanded wire gauge support (12-30 AWG).

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1985933 provides direct pitch compatibility (5.00mm) with the Molex 0395932003, making it the preferred substitute when PCB layout constraints are strict. This part maintains identical position count and mating orientation while delivering doubled current capacity (20 A vs. 10 A) and extended wire gauge support (12-30 AWG). Both components are Active products with ROHS3 compliance and unlimited moisture sensitivity rating.

Phoenix Contact 1985959 offers an alternative with 5.08mm pitch spacing. This part is suitable for applications where minor PCB footprint adjustments are acceptable. It provides the same electrical performance advantages as the 1985933 (20 A current, 12-30 AWG wire gauge) and maintains full compliance requirements.

Selection between these substitutes depends on PCB layout constraints. The 1985933 is recommended for direct replacement scenarios requiring identical pitch. The 1985959 is applicable when PCB redesign or tolerance accommodation is feasible.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1985933 replace Molex 0395932003 without PCB modification?

A: Yes. Both parts share identical 5.00mm pitch and horizontal board-mount orientation, enabling direct substitution without PCB layout changes.

Q: What is the pitch difference between 1985933 and 1985959?

A: The 1985933 uses 5.00mm pitch (matching the original Molex part), while the 1985959 uses 5.08mm pitch. This 0.08mm difference requires PCB footprint verification before substitution.

Q: Are the wire termination methods interchangeable?

A: The Molex 0395932003 uses screw-leaf spring termination with wire guard, while both Phoenix Contact substitutes use screw-rising cage clamp termination. Both methods are screw-based and functionally equivalent for wire retention, though installation procedures may differ.

Q: Do the substitute parts support the same wire gauge range?

A: The Molex part supports 14-24 AWG. Both Phoenix Contact substitutes support 12-30 AWG, providing expanded compatibility. Applications using 14-24 AWG wire are fully compatible with either substitute.

Q: Are all three parts RoHS3 compliant?

A: Yes. The Molex 0395932003 and both Phoenix Contact substitutes (1985933 and 1985959) are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: What is the current rating advantage of the substitutes?

A: The Molex part is rated for 10 A, while both Phoenix Contact substitutes are rated for 20 A. Applications requiring higher current capacity benefit from the substitute parts.
