Phoenix Contact 1900138 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1900138 is an 8-position terminal block header with male pins, shrouded on four sides, featuring a 0.197" (5.00mm) pitch and 90° right-angle orientation for through-hole mounting. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations.

The primary reason for identifying substitute parts is the obsolete product status of the 1900138. Active equivalent models provide continuity for applications requiring identical electrical and mechanical performance while ensuring access to current inventory and ongoing manufacturer support.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Phoenix Contact 1900138 are identified based on strict equivalence across the following critical parameters:

• Electrical Performance: Current and voltage ratings (IEC and UL standards)
• Physical Configuration: 8 positions, 0.197" (5.00mm) pitch, 90° right-angle orientation
• Connector Type: Male pins with 4-side shrouding
• Mounting Method: Through-hole termination
• Contact Interface: Tin mating finish
• Compliance: RoHS and flammability ratings

The identified substitutes (1776757 and 1836748) maintain these core parameters while differing in termination style (solder vs. press-fit), housing material, contact tail length, and product status. These differences are documented to enable informed selection based on specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1776757 is the primary substitute for the 1900138. Both components share identical electrical ratings (12A IEC, 15A UL), pitch, orientation, and shrouding configuration. The 1776757 maintains PBT housing material and equivalent insulation height. The primary difference is termination style (solder vs. press-fit) and slightly shorter contact tail length (0.138" vs. 0.165"). The 1776757 holds active product status with ROHS3 compliance, ensuring current availability and manufacturer support.

Phoenix Contact 1836748 provides an alternative substitute with active product status and ROHS3 compliance. This component maintains the 8-position, 5.00mm pitch, and 90° right-angle configuration. Differences include solder termination, LCP housing material, significantly shorter contact tail length (0.079"), reduced insulation height (0.298"), and black color. The 1836748 supports 16A UL current rating and specifies -40°C operating temperature. Selection of this substitute requires confirmation that the reduced contact tail length and different housing material are compatible with the target PCB design and thermal requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1776757 directly replace the 1900138 in existing designs?

A: The 1776757 maintains electrical equivalence (12A IEC, 15A UL, 400V IEC, 300V UL) and identical pitch and orientation. The primary consideration is termination method: the 1900138 uses press-fit termination while the 1776757 uses solder termination. PCB pad design and assembly process compatibility must be confirmed. Contact tail length differs (0.165" vs. 0.138"), which may affect PCB stack-up calculations.

Q: What are the key differences between the 1776757 and 1836748?

A: Both are solder-terminated alternatives to the obsolete 1900138. The 1776757 maintains PBT housing and 0.339" insulation height identical to the original part. The 1836748 uses LCP housing with reduced insulation height (0.298") and significantly shorter contact tail (0.079" vs. 0.165"). The 1836748 supports higher UL current (16A vs. 15A) and specifies -40°C operating temperature. Housing material and dimensional differences require PCB design verification.

Q: Are all three parts RoHS compliant?

A: The 1900138 is RoHS Compliant. Both substitutes (1776757 and 1836748) are ROHS3 Compliant, representing current regulatory compliance standards. All three components have MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions.

Q: Does color difference between parts affect functionality?

A: The 1900138 and 1776757 are green; the 1836748 is black. Color is a visual identifier only and does not affect electrical or mechanical performance. Selection should be based on application requirements for visual identification or documentation standards.

Q: What is the impact of different housing materials?

A: The 1900138 and 1776757 use PBT (Polybutylene Terephthalate). The 1836748 uses LCP (Liquid Crystal Polymer). Both materials meet UL94 V-0 flammability requirements for the original part (1836748 flammability rating not specified). LCP offers superior dimensional stability and higher temperature performance. Material selection depends on thermal environment and mechanical stress requirements of the specific application.
