Molex 0395315504 Terminal Block Header – Equivalent & Substitute Parts

Part Overview

The Molex 0395315504 is a 4-position terminal block header with male pins, shrouded on 2 sides, designed for vertical through-hole mounting with 5.08mm pitch spacing. This component is part of the Eurostyle ESE 39531 series and is currently in active production status. Finding equivalent or substitute parts may be necessary due to inventory constraints, lead time requirements, or specific application compatibility needs where alternative electrical or mechanical specifications are acceptable within system design parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0395315504 with the Weidmüller 1581800000 is based on the following alignment of critical parameters:

Matching Parameters:

• 4-position configuration with single level
• Vertical through-hole mounting orientation
• Solder termination style
• 15 A current rating (UL specification)
• 300 V voltage rating (UL specification)
• UL94 V-0 flammability rating
• Active product status with current availability
• Identical insulation height (0.472" / 12.00mm)

Allowable Variations:

• Pitch tolerance: 0.200" (5.08mm) vs. 0.197" (5.00mm) – within acceptable mechanical tolerance for standard PCB footprints
• Shrouding configuration: 2-side vs. 4-side – both provide adequate electrical isolation
• Contact mating finish: Gold vs. Tin – both meet solder joint reliability requirements
• Housing material: PA66 Nylon 6/6 vs. PBT – both meet UL94 V-0 requirements
• Contact material: Brass vs. Copper Alloy – both provide equivalent electrical conductivity
• Operating temperature range: -40°C ~ 105°C vs. -50°C ~ 100°C – overlapping operational envelope

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0395315504 and Weidmüller 1581800000 maintain active product status with current manufacturing and inventory availability. Both components meet UL94 V-0 flammability requirements and carry equivalent RoHS compliance certifications. The electrical performance specifications—15 A current rating and 300 V voltage rating under UL standards—are identical between the two parts.

The Weidmüller 1581800000 offers enhanced shrouding (4-side vs. 2-side), which provides additional electrical isolation. The pitch difference of 0.08mm (5.08mm vs. 5.00mm) falls within standard PCB manufacturing tolerances and does not preclude direct substitution on existing circuit board layouts designed for 5.08mm spacing.

Selection between these parts should be based on inventory availability, lead time requirements, and specific application constraints related to shrouding configuration or housing material compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1581800000 be used as a direct replacement for the Molex 0395315504 on existing PCB designs?

A: The pitch difference of 0.08mm (5.08mm vs. 5.00mm) is within standard PCB manufacturing tolerances. However, PCB footprints must be verified for accommodation of the 5.00mm pitch before substitution. The identical insulation height and through-hole mounting configuration support mechanical compatibility.

Q: What is the significance of the shrouding difference (2-side vs. 4-side)?

A: Both configurations provide electrical isolation between adjacent contacts. The 4-side shrouding of the Weidmüller part offers enhanced isolation and may be preferred in applications with higher electromagnetic interference sensitivity or tighter spacing constraints.

Q: Are the electrical ratings equivalent between these two parts?

A: Yes. Both parts carry identical UL ratings: 15 A current and 300 V voltage. Both meet UL94 V-0 flammability requirements and are RoHS compliant.

Q: Does the contact material difference (Brass vs. Copper Alloy) affect solder joint reliability?

A: Both brass and copper alloy contacts provide equivalent electrical conductivity and solder joint reliability. The contact mating finish (gold vs. tin) is the primary factor influencing solder joint performance, and both finishes meet industry standards for through-hole solder termination.

Q: What is the operating temperature overlap between these parts?

A: The Molex part operates from -40°C to 105°C, while the Weidmüller part operates from -50°C to 100°C. The overlapping range is -40°C to 100°C, which covers standard industrial and commercial temperature requirements.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are active products with current manufacturing status. The Molex part carries ROHS3 compliance, while the Weidmüller part carries RoHS compliance. Both meet UL94 V-0 flammability standards. The Weidmüller part includes REACH Unaffected status.
