Phoenix Contact 1900235 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1900235 is an 18-position terminal block header with male pins, shrouded on four sides, featuring 0.197" (5.00mm) pitch and 90° right-angle through-hole mounting. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity. The part operates at IEC ratings of 12A/400V and UL ratings of 15A/300V, with UL94 V-0 flammability compliance and RoHS certification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1900235 is determined by the following critical parameters:

• Position Count & Pitch: 18 positions at 0.197" (5.00mm) spacing (non-negotiable for mechanical fit)
• Header Type & Orientation: Male pins, shrouded (4 side), 90° right-angle configuration
• Mounting Method: Through-hole termination
• Electrical Ratings: Minimum IEC 12A/400V and UL 15A/300V compliance
• Flammability & Compliance: UL94 V-0 rating and RoHS certification required

The two identified substitutes (1776854 and 1836845) maintain these core parameters while differing in termination style (solder vs. press-fit), series designation, housing material, and contact tail geometry. These variations are acceptable within the substitution framework as they do not affect the primary electrical or mechanical interface requirements.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts (1776854 and 1836845) are active products from Phoenix Contact and maintain full compliance with the electrical and mechanical requirements of the obsolete 1900235.

1776854 (COMBICON MSTB Series): This substitute shares identical electrical ratings (12A IEC/15A UL) and mechanical pitch with the main part. The primary difference is termination style (solder vs. press-fit) and a reduced contact tail length (0.138" vs. 0.165"). This part is suitable for applications where solder termination is acceptable and PCB design accommodates the shorter tail geometry.

1836845 (COMBICON CC Series): This substitute maintains the 18-position, 5.00mm pitch configuration with equivalent electrical performance (12A IEC/16A UL). The housing material differs (LCP vs. PBT), and the contact tail is significantly shorter (0.079"). This part includes specified operating temperature range (-40°C ~ 100°C) and is suitable for applications requiring enhanced thermal or chemical resistance properties of LCP material.

Both substitutes carry RoHS compliance and UL94 V-0 flammability certification, ensuring regulatory alignment with the original part.

Frequently Asked Questions (FAQ)

Q: Can 1776854 and 1836845 be used interchangeably with 1900235?

A: Both parts maintain the critical mechanical and electrical parameters (18 positions, 5.00mm pitch, 90° right-angle, through-hole mounting, 12A IEC/15A UL minimum ratings). However, termination style and contact tail length differ. PCB design must accommodate these variations. Solder termination (both substitutes) differs from press-fit (original), requiring assembly process adjustment.

Q: What is the impact of different contact tail lengths?

A: Contact tail length affects PCB hole depth and solder joint geometry. The main part (0.165") has longer tails than 1776854 (0.138") and 1836845 (0.079"). PCB design must be verified to ensure adequate hole depth and solder fillet formation for the selected substitute.

Q: Are there color or material differences that affect functionality?

A: The main part is green (PBT housing); 1776854 is green (PBT housing); 1836845 is black (LCP housing). These are cosmetic and material property differences. LCP material in 1836845 offers enhanced thermal and chemical resistance compared to PBT. Color and material do not affect electrical performance or mechanical fit.

Q: Which substitute should be selected for new designs?

A: Both active substitutes are suitable. Selection depends on termination preference (solder), PCB layout constraints (contact tail length), and environmental requirements (operating temperature range specified for 1836845). Verify PCB design compatibility with the selected substitute's contact tail geometry.

Q: Are all substitutes RoHS compliant?

A: Yes. The main part and both substitutes are RoHS compliant with UL94 V-0 flammability rating and MSL 1 (unlimited moisture sensitivity level).
