Molex 0395259010 Terminal Block Header – Equivalent & Substitute Parts

Part Overview

The Molex 0395259010 is a 10-position vertical terminal block header with 5.00mm pitch, designed for through-hole solder mounting. This component is part of the Eurostyle ESE 39525 series and is classified as Active product status. The shrouded 4-side design provides mechanical stability and electrical isolation. Substitute parts are identified when equivalent electrical ratings, mechanical dimensions, and connector compatibility align with the original specification, enabling direct replacement in applications where component availability or supply chain requirements necessitate alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0395259010 are qualified based on the following critical parameters:

• Electrical Compatibility: Current and voltage ratings must meet or exceed the original specification (15 A UL, 300 V UL minimum).
• Mechanical Compatibility: 10-position count, vertical orientation, and through-hole solder termination are mandatory.
• Pitch Tolerance: Pitch must be 5.00mm or 5.08mm (within standard manufacturing tolerance for Eurostyle connectors).
• Connector Type: Male pins with 4-side shrouding required for mechanical and electrical equivalence.
• Regulatory Compliance: RoHS3 compliance and UL94 V-0 flammability rating required.

The two identified substitutes (Phoenix Contact 1776964 and 1777154) meet these criteria with minor pitch variation (5.08mm vs. 5.00mm) that remains within acceptable tolerance for standard terminal block applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: Phoenix Contact 1776964

The Phoenix Contact 1776964 provides direct electrical and mechanical equivalence to the Molex 0395259010. Both components share identical pitch (5.00mm), position count (10), orientation (vertical), and UL voltage rating (300 V). The 1776964 maintains ROHS3 compliance and UL94 V-0 flammability rating. The current rating differential (12 A vs. 15 A) is acceptable in applications where the circuit design operates within the 12 A threshold. This part is Active status and suitable for direct replacement.

Secondary Substitute: Phoenix Contact 1777154

The Phoenix Contact 1777154 offers functional equivalence with a pitch variation of 5.08mm (0.200") compared to the original 5.00mm specification. This minor pitch difference (0.08mm) falls within standard manufacturing tolerance for Eurostyle terminal block connectors and does not affect mechanical or electrical performance in standard PCB applications. The 1777154 maintains identical position count, orientation, voltage rating (300 V UL), and regulatory compliance (ROHS3, UL94 V-0). The current rating (12 A) applies the same consideration as the primary substitute. This part is Active status.

Both substitutes are qualified based on Active product status, full regulatory compliance, and electrical parameter alignment with the original specification.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1776964 be used as a direct replacement for Molex 0395259010?

A: Yes. Both components share identical pitch (5.00mm), 10-position configuration, vertical orientation, solder termination, and UL voltage rating (300 V). The current rating difference (12 A vs. 15 A) requires circuit design verification to confirm operation within the lower threshold. Both are Active status with ROHS3 compliance and UL94 V-0 rating.

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

A: The 0.08mm pitch variation between the Molex 0395259010 (5.00mm) and Phoenix Contact 1777154 (5.08mm) is within standard manufacturing tolerance for Eurostyle terminal block connectors. This difference does not affect mechanical fit or electrical performance in standard through-hole PCB applications where connector spacing is designed for standard pitch families.

Q: Are both Phoenix Contact substitutes electrically equivalent?

A: Both Phoenix Contact parts (1776964 and 1777154) meet the electrical requirements of the original Molex component with respect to voltage rating (300 V UL) and flammability (UL94 V-0). The current rating for both substitutes is 12 A, which is lower than the original 15 A rating. Circuit design must confirm operation within this reduced current threshold.

Q: What regulatory certifications apply to these substitute parts?

A: All three components (Molex 0395259010 and both Phoenix Contact substitutes) are ROHS3 compliant and carry UL94 V-0 flammability rating. Both Phoenix Contact parts include REACH Unaffected status. All components are classified as Active product status.

Q: Can these parts be used interchangeably in existing designs?

A: The Phoenix Contact 1776964 provides direct mechanical and electrical interchangeability with identical pitch and electrical ratings (within the 12 A current limitation). The Phoenix Contact 1777154 is mechanically compatible with the minor pitch tolerance noted above. Both require verification that circuit current requirements do not exceed 12 A.
