Molex 0395250002 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Molex 0395250002 is a 2-position terminal block header with male pins, shrouded design, and 5.00mm pitch for vertical through-hole mounting. This component is classified as Active product status and is designed for applications requiring reliable electrical connections in industrial and commercial equipment. Substitute parts become necessary when the primary component faces supply constraints, extended lead times, or when design flexibility permits the use of mechanically and electrically compatible alternatives from different manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0395250002 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Substitution Criteria:

• Number of positions: 2 (exact match required)
• Type: Header with male pins and shrouded (4-side) design (exact match required)
• Header orientation: Vertical (exact match required)
• Mounting type: Through hole (exact match required)
• Termination style: Solder (exact match required)
• Material flammability rating: UL94 V-0 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

Allowable Parameter Variations:

• Pitch tolerance: 0.197" (5.00mm) to 0.200" (5.08mm) — minor pitch variation acceptable within standard PCB layout tolerances
• Current rating: 15 A minimum (UL standard)
• Voltage rating: 300 V minimum (UL standard)
• Operating temperature range: -20°C to 105°C acceptable (overlap with original -40°C to 105°C)
• Contact material: Brass or copper alloy
• Housing material: Polyamide (PA66/PA) or Liquid Crystal Polymer (LCP)
• Contact mating finish: Tin (standard)

The two substitute parts listed below meet all primary criteria and fall within allowable parameter variations.

Engineering Selection Recommendations

Weidmüller 1776364001 (Omnimate SL Series)

This substitute is qualified for direct replacement in applications where the 0.059" (1.50mm) contact tail length is compatible with PCB through-hole specifications. The Weidmüller part maintains UL94 V-0 flammability rating, ROHS3 compliance, and meets or exceeds electrical specifications (15 A at 300 V UL). Operating temperature range (-20°C to 100°C) is suitable for standard industrial applications but does not extend to the -40°C lower limit of the original part. Solder retention feature provides additional manufacturing robustness.

Phoenix Contact 1924525 (COMBICON MSTBV Series)

This substitute is qualified for direct replacement in applications where the 0.154" (3.90mm) contact tail length and green housing color are acceptable. The Phoenix Contact part exceeds electrical specifications (16 A at 300 V UL) and maintains UL94 V-0 flammability rating and ROHS3 compliance. Operating temperature range is not specified in available data. Mating and mounting flange design provides enhanced mechanical stability.

Both substitutes are Active product status components with established supply availability and full regulatory compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1776364001 be used as a direct PCB replacement for the Molex 0395250002?

A: The Weidmüller part is mechanically and electrically compatible for vertical through-hole mounting applications. However, the contact tail length differs (0.059" versus 0.150"), which may require PCB layout verification to confirm hole depth compatibility. Pitch variation (5.08mm versus 5.00mm) is within standard tolerance for PCB design.

Q: What is the significance of the pitch difference between 5.00mm and 5.08mm?

A: The 0.08mm pitch difference represents a 1.6% variation. Standard PCB design tolerances typically accommodate this variation. However, applications with tight mechanical constraints or custom PCB layouts should verify hole spacing compatibility before implementation.

Q: Does the Phoenix Contact 1924525 green housing color affect electrical performance?

A: Housing color is a visual identification feature only and does not affect electrical performance, current rating, voltage rating, or thermal characteristics. The green color is a standard identifier for the COMBICON MSTBV series.

Q: Are both substitute parts suitable for low-temperature applications requiring -40°C operation?

A: The Weidmüller part specifies -20°C minimum operating temperature, which does not meet the -40°C requirement of the original Molex part. The Phoenix Contact operating temperature range is not specified. For applications requiring -40°C operation, the original Molex 0395250002 is the specified component.

Q: What is the impact of different contact tail lengths on soldering?

A: Contact tail length affects solder joint formation and PCB hole depth requirements. The Molex part (0.150"), Weidmüller part (0.059"), and Phoenix Contact part (0.154") have different tail lengths. PCB design must accommodate the selected component's tail length to ensure proper solder fillet formation and mechanical strength.

Q: Are all three parts RoHS3 compliant?

A: Yes. The Molex 0395250002, Weidmüller 1776364001, and Phoenix Contact 1924525 are all ROHS3 compliant, meeting current environmental and hazardous substance restrictions.

Q: What packaging formats are available for these parts?

A: Molex 0395250002 is supplied in Bulk packaging. Weidmüller 1776364001 is supplied in Cut Tape (CT) packaging. Phoenix Contact 1924525 is supplied in Bulk packaging. Packaging format selection depends on production volume and assembly process requirements.
