Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1902864 is determined by the following critical parameters:

• Position Count & Pitch: 7 positions at 0.200" (5.08mm) spacing
• Connector Type & Orientation: Header with male pins, shrouded (4 side), vertical mounting
• Electrical Ratings: Minimum 12A current capacity and 300V voltage rating (UL standard)
• Termination Method: Solder-based through-hole connection
• Compliance Standards: RoHS compliance and UL94 V-0 flammability rating

The substitute part Phoenix Contact 1955905 meets all critical substitution criteria. Both components share identical position count, pitch, connector type, orientation, and termination method. Both maintain RoHS compliance and UL94 V-0 flammability rating. Electrical ratings remain compatible within specified operating parameters.

Engineering Selection Recommendations

The Phoenix Contact 1955905 is the primary substitute for the obsolete 1902864 terminal block header. Selection is based on the following engineering factors:

Product Status: The 1955905 maintains active product status, ensuring continued availability and supply chain reliability compared to the obsolete 1902864.

Electrical Compatibility: Both components meet IEC electrical standards at 12A and 400V. The 1955905 operates at 10A under UL standards versus 12A for the 1902864; this represents a 2A reduction in UL current capacity. Applications operating within 10A UL limits experience no functional impact.

Compliance & Certification: Both parts maintain RoHS compliance and UL94 V-0 flammability rating, satisfying regulatory requirements for equivalent applications.

Physical Considerations: The 1955905 features Liquid Crystal Polymer (LCP) housing versus Polyamide (PA) nylon in the 1902864, providing improved thermal and chemical resistance. Contact tail length differs by 0.044" (1.10mm) and insulation height by 0.008" (0.20mm); these dimensional variations require PCB layout verification for through-hole mounting compatibility. The 1955905 demonstrates superior moisture resistance (MSL 1 versus MSL 3).

Frequently Asked Questions (FAQ)

Q: Can the 1955905 directly replace the 1902864 in existing designs?

A: Direct replacement is possible for applications operating within 10A UL current limits. PCB layout verification is required due to differences in contact tail length (0.146" versus 0.102") and insulation height (0.480" versus 0.472"). Mechanical fit must be confirmed before implementation.

Q: What is the significance of the housing material change from Polyamide to Liquid Crystal Polymer?

A: Liquid Crystal Polymer provides superior thermal stability, chemical resistance, and dimensional consistency compared to Polyamide. This material upgrade enhances long-term reliability and environmental performance in the 1955905.

Q: Are there electrical limitations when substituting the 1955905 for the 1902864?

A: Under IEC standards, both components operate identically at 12A and 400V. Under UL standards, the 1955905 is rated at 10A versus 12A for the 1902864. Applications requiring UL compliance must confirm operation within the 10A limit.

Q: What does the MSL rating difference indicate?

A: The 1902864 carries MSL 3 (168-hour moisture sensitivity), while the 1955905 carries MSL 1 (unlimited moisture sensitivity). The 1955905 demonstrates superior resistance to moisture absorption and environmental stress, reducing handling and storage constraints.

Q: Are both parts RoHS compliant?

A: Yes, both the 1902864 and 1955905 are RoHS compliant and maintain UL94 V-0 flammability certification, satisfying regulatory requirements for equivalent applications.
