Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0395432003 is determined by the following critical parameters:

• Electrical Compatibility: Voltage rating (300 V minimum), current capacity (10 A minimum), and wire gauge acceptance (14-24 AWG minimum range)
• Mechanical Compatibility: 3-position configuration, through-hole mounting, horizontal board orientation, and pitch tolerance within 5.00mm ± 0.08mm
• Termination Method: Screw-based wire termination with equivalent clamping force and wire retention
• Environmental Compliance: RoHS3 compliance and operating temperature range support

The identified substitute parts meet these criteria while maintaining functional equivalence for wire-to-board connection applications.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1985933 qualifies as a direct substitute based on matching pitch (5.00mm), voltage (300 V), position count (3), and through-hole mounting configuration. This part exceeds the current rating requirement (20 A vs. 10 A) and expands wire gauge acceptance (12-30 AWG vs. 14-24 AWG). Both parts maintain RoHS3 compliance and Active product status. The termination method differs (rising cage clamp vs. leaf spring), but both employ screw-based wire retention.

Phoenix Contact 1985959 provides substitution with a pitch variance of 0.08mm (5.08mm vs. 5.00mm). This tolerance may require PCB layout verification for through-hole alignment. Current and voltage ratings match the 1985933 specification. RoHS3 compliance and Active status are maintained. Pitch deviation necessitates mechanical compatibility assessment before deployment.

Both Phoenix Contact alternatives are suitable for applications where the Molex 0395432003 is unavailable, provided that PCB footprint and mechanical constraints accommodate the specified pitch and termination geometry.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1985933 replace Molex 0395432003 in existing designs?

A: Yes. Both parts share identical pitch (5.00mm), voltage rating (300 V), position count (3), and through-hole mounting. The Phoenix Contact part accepts a wider wire gauge range (12-30 AWG) and provides higher current capacity (20 A). Termination method differs (rising cage clamp vs. leaf spring), but both employ screw-based clamping. No PCB redesign is required.

Q: What is the pitch difference between Molex 0395432003 and Phoenix Contact 1985959?

A: Phoenix Contact 1985959 has a pitch of 5.08mm compared to the Molex part's 5.00mm pitch. This 0.08mm difference may affect through-hole alignment on existing PCBs. Mechanical compatibility must be verified before substitution.

Q: Are all three parts RoHS3 compliant?

A: Yes. Molex 0395432003, Phoenix Contact 1985933, and Phoenix Contact 1985959 are all RoHS3 compliant and maintain Active product status.

Q: What wire gauges are supported by each part?

A: Molex 0395432003 supports 14-24 AWG. Both Phoenix Contact alternatives (1985933 and 1985959) support 12-30 AWG, providing broader wire gauge compatibility.

Q: Do the substitute parts have different current ratings?

A: Yes. Molex 0395432003 is rated for 10 A, while both Phoenix Contact alternatives are rated for 20 A. The higher rating of the substitutes does not prevent their use in 10 A applications.
