Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1902806 is determined by the following critical parameters:

• Electrical Compatibility: Current and voltage ratings must meet or exceed IEC 12A/400V and UL 15A/300V specifications
• Physical Configuration: 8-position count, 0.200" (5.08mm) pitch, and 90° right-angle orientation are mandatory
• Connector Type: Male pins with four-side shrouding required for mechanical and electrical safety
• Termination Method: Solder termination for PCB integration
• Mounting Standard: Through-hole mounting compatibility
• Regulatory Compliance: UL94 V-0 flammability rating and RoHS compliance

The Phoenix Contact 1954980 qualifies as a direct substitute based on these parameters. Both components share identical functional specifications for position count, pitch, orientation, and termination method. The 1954980 operates within the required electrical envelope and maintains equivalent mechanical compatibility despite differences in housing material composition and minor dimensional variations in contact tail length and insulation height.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1954980 is the designated substitute for the obsolete 1902806 based on the following engineering criteria:

Product Status Alignment: The 1954980 maintains active production status, ensuring long-term availability and supply chain continuity. The 1902806 is classified as obsolete, necessitating transition to an equivalent active component.

Electrical Performance: Both components meet IEC electrical specifications at 12A/400V. The 1954980 specifies 10A under UL conditions compared to the 1902806's 15A rating. This represents a conservative specification that remains suitable for applications within the 10A envelope. Applications requiring the full 15A UL capacity must be evaluated against actual circuit requirements.

Regulatory Compliance: Both components achieve UL94 V-0 flammability classification and maintain RoHS compliance. The 1954980 carries ROHS3 certification, representing current regulatory alignment.

Physical Compatibility: Identical pitch (5.08mm), position count (8), orientation (90° right angle), and termination method (solder) ensure mechanical and electrical interchangeability on PCB layouts. Minor dimensional variations in contact tail length (0.114" vs. 0.102") and insulation height (0.350" vs. 0.339") fall within standard manufacturing tolerances and do not affect functional compatibility.

Material Specification: The 1954980 uses Liquid Crystal Polymer (LCP) housing versus polyamide (PA) nylon in the 1902806. Both materials achieve identical flammability ratings and maintain equivalent electrical insulation properties for this application class.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1954980 be used as a direct replacement for the 1902806 in existing designs?

A: Yes, the 1954980 qualifies as a direct substitute. Both components share identical pitch (5.08mm), position count (8), orientation (90°), and termination method (solder). Physical dimensions vary minimally and remain within standard tolerances. Verify that your application operates within the 1954980's UL current specification of 10A.

Q: What is the significance of the housing material difference between these parts?

A: The 1902806 uses polyamide (PA) nylon while the 1954980 uses Liquid Crystal Polymer (LCP). Both materials achieve UL94 V-0 flammability classification and provide equivalent electrical insulation for this component class. Material selection does not affect electrical performance or mechanical compatibility in standard terminal block applications.

Q: Are there any dimensional concerns when substituting the 1954980 for the 1902806?

A: Contact tail length differs by 0.012" (0.30mm) and insulation height by 0.011" (0.28mm). These variations are within standard manufacturing tolerances for terminal block connectors and do not affect PCB footprint compatibility or mating performance.

Q: Does the 1954980 meet the same regulatory requirements as the 1902806?

A: Both components achieve UL94 V-0 flammability rating and maintain RoHS compliance. The 1954980 carries ROHS3 certification, representing current regulatory standards. Both are classified as EAR99 for export control purposes.

Q: What is the difference between IEC and UL current ratings for these components?

A: IEC and UL represent different international testing and certification standards. The 1902806 is rated at 12A (IEC) and 15A (UL). The 1954980 is rated at 12A per position (IEC) and 10A (UL). Applications must comply with the applicable standard for their region and use case.

Q: Is the 1954980 available in the same packaging as the 1902806?

A: The 1902806 is listed with unspecified packaging, while the 1954980 is supplied in bulk packaging. Verify packaging requirements with your procurement specifications.
