Weidmüller 1972850000 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Weidmüller 1972850000 is a 16-position terminal block header with male pins, shrouded on four sides, designed for 0.150" (3.81mm) pitch right-angle through-hole mounting. This component is part of the Omnimate SC series and is currently in active production status. Finding equivalent substitute parts may be necessary due to supply constraints, lead time requirements, or specific application compatibility needs while maintaining electrical and mechanical performance standards.

Parameter Comparison

Engineering Selection Recommendations

Both the Weidmüller 1972850000 and Phoenix Contact 1843130 are active production components with full RoHS and REACH compliance. Selection between these parts should be based on the following criteria:

Weidmüller 1972850000 is the primary choice when:

• Application current requirements exceed 8A IEC or 8A UL ratings
• Omnimate SC series compatibility is specified
• Orange housing color is required for circuit identification
• Glass-filled polyamide housing is preferred for mechanical rigidity

Phoenix Contact 1843130 is suitable when:

• Application current requirements do not exceed 8A IEC or 8A UL
• COMBICON MCD series compatibility is acceptable
• Green housing color is acceptable for circuit identification
• Standard polyamide nylon housing meets mechanical requirements
• Supply availability or lead time favors this alternative

Both components meet identical voltage specifications (320V IEC, 300V UL), flammability ratings (UL94 V-0), and compliance certifications. The contact tail length variation (0.126" vs 0.138") is within acceptable PCB design tolerances for through-hole solder applications.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1843130 be used as a direct replacement for Weidmüller 1972850000?

A: Yes, for applications where current requirements do not exceed 8A IEC or 8A UL. Both components share identical mechanical dimensions, pitch, position count, voltage ratings, and flammability certifications. The primary difference is current rating capacity.

Q: What is the significance of the current rating difference between these parts?

A: The Weidmüller 1972850000 is rated for 17.5A IEC and 10A UL, while the Phoenix Contact 1843130 is rated for 8A IEC and 8A UL. If your application requires current handling above 8A, the Weidmüller part is the appropriate choice. For applications at or below 8A, both parts are electrically equivalent.

Q: Are the housing materials compatible with the same connector systems?

A: Both parts use polyamide (nylon) housing materials with identical shrouded four-side configurations and 0.150" (3.81mm) pitch. The Weidmüller housing includes glass-fill reinforcement, while the Phoenix Contact housing uses standard polyamide nylon. Both are mechanically compatible with standard 3.81mm pitch connector systems.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both components are RoHS compliant (Weidmüller: RoHS Compliant; Phoenix Contact: ROHS3 Compliant), REACH Unaffected, and carry UL94 V-0 flammability ratings. Both meet 320V IEC and 300V UL voltage specifications.

Q: What is the difference in contact tail length, and does it affect PCB compatibility?

A: The Weidmüller 1972850000 has a contact tail length of 0.126" (3.20mm), while the Phoenix Contact 1843130 has 0.138" (4.60mm). This 0.012" (0.30mm) variation is within standard PCB design tolerances for through-hole solder applications and does not affect functional compatibility.

Q: Are both parts available in the same packaging format?

A: Yes. Both components are supplied in bulk packaging as new original stock, suitable for standard component procurement and assembly processes.
