Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for terminal block headers is determined by the following critical parameters:

• Position Count & Pitch: Both main part and substitute must have identical 11 positions at 5.08mm pitch to ensure mechanical and electrical compatibility with mating connectors
• Header Orientation: Vertical orientation is required for through-hole PCB mounting compatibility
• Termination Style: Solder termination is mandatory for direct replacement in existing PCB designs
• Electrical Ratings: Substitute parts must meet or exceed the application's voltage and current requirements (IEC 400V/27.5A or UL 300V/18.5A)
• Mounting Type: Through-hole mounting is required for PCB integration
• Compliance Standards: RoHS compliance and UL94 V-0 flammability rating ensure regulatory and safety alignment

The Phoenix Contact 1921641 qualifies as a substitute based on matching position count, pitch, vertical orientation, solder termination, through-hole mounting, and compliance certifications. However, electrical rating differences exist and must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1921641 is available as an active product, addressing the obsolescence status of the Weidmüller 1775692001. Both components maintain UL94 V-0 flammability compliance and RoHS certification, ensuring regulatory alignment.

Key considerations for selection:

Electrical Capacity: The Phoenix Contact 1921641 operates at reduced current ratings (12A IEC/UL versus 27.5A/18.5A for the Weidmüller). Applications requiring the full current capacity of the original part cannot use this substitute without circuit redesign.

Shrouding Configuration: The substitute features 4-side shrouding compared to the original 2-side shrouding. This provides enhanced mechanical protection and may affect PCB layout compatibility depending on adjacent component placement.

Contact Finish: The substitute uses gold plating versus tin on the original. Gold plating provides superior corrosion resistance and contact reliability in demanding environments.

Voltage Ratings: Both components support 400V IEC and 300V UL ratings, maintaining voltage compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1921641 directly replace the Weidmüller 1775692001 in existing designs?

A: Direct replacement is possible only if the application current requirement does not exceed 12A. The Phoenix Contact part has lower current ratings (12A IEC/UL) compared to the original (27.5A IEC/18.5A UL). Verify your circuit's maximum current draw before substitution.

Q: What is the difference between 2-side and 4-side shrouding?

A: 2-side shrouding provides protection on two opposing sides of the connector. 4-side shrouding extends protection to all four sides, offering increased mechanical robustness and EMI shielding. The 4-side configuration may require verification of PCB layout clearances around the component.

Q: Are the pitch and position count identical between these parts?

A: Yes. Both components have 11 positions at 5.08mm pitch, ensuring mechanical compatibility with existing mating connectors and PCB footprints.

Q: Do both parts meet the same compliance standards?

A: Both components are RoHS compliant and carry UL94 V-0 flammability ratings. The Phoenix Contact part is currently active in production, while the Weidmüller part is obsolete.

Q: What is the significance of the contact finish difference?

A: The Weidmüller uses tin plating; the Phoenix Contact uses gold plating. Gold provides superior corrosion resistance and contact reliability, particularly in high-humidity or corrosive environments. Tin is adequate for standard industrial applications.

Q: Are the insulation heights compatible?

A: Yes. Both components have identical insulation heights of 0.472" (12.00mm), ensuring consistent PCB assembly and spacing with other components.
