Phoenix Contact 1900248 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1900248 is a 19-position terminal block header with male pins, shrouded on four sides, featuring 0.197" (5.00mm) pitch and 90° right-angle orientation for through-hole mounting. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations. The part operates at IEC ratings of 12A/400V and UL ratings of 15A/300V, with press-fit termination and UL94 V-0 flammability compliance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1900248 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: 19 positions, 0.197" (5.00mm) pitch, 90° right-angle orientation, and through-hole mounting are mandatory
• Connector Type: Male pins with four-sided shrouding required
• Compliance: UL94 V-0 flammability rating and RoHS compliance required
• Contact Finish: Tin plating required for mating surfaces

Two substitute parts meet these criteria with variations in termination style, housing material, and contact tail length. Both maintain electrical performance within acceptable parameters while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1776867 is suitable for applications where solder termination is acceptable and IEC voltage rating of 320V meets system requirements. This part maintains identical pitch, position count, and shrouding configuration while offering active product status and improved long-term availability. The reduced contact tail length (0.138" vs. 0.165") requires verification of PCB pad layout compatibility.

Phoenix Contact 1836858 provides the highest current rating (16A UL) and active product status with extended operating temperature range (-40°C to 100°C). The Liquid Crystal Polymer housing offers superior thermal and mechanical properties compared to PBT. The significantly shorter contact tail length (0.079") necessitates PCB design review to ensure adequate solder joint formation and mechanical support. The black color differs from the original green specification.

Both substitutes maintain UL94 V-0 compliance, RoHS compliance, and tin contact finish. Selection between these options depends on termination method compatibility with existing PCB design and mechanical clearance requirements for contact tail length.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1776867 directly replace 1900248 in existing designs?

A: Electrical and mechanical compatibility is confirmed for pitch, position count, and connector type. The primary difference is termination style change from press-fit to solder. PCB pad layout must be verified to accommodate the 0.138" contact tail length versus the original 0.165" specification.

Q: What is the impact of housing material change from PBT to LCP in part 1836858?

A: Liquid Crystal Polymer offers improved thermal stability and mechanical strength compared to Polybutylene Terephthalate. This change does not affect electrical performance or compliance ratings. Material selection depends on application thermal and mechanical requirements.

Q: Are there color implications for using the black 1836858 instead of green 1900248?

A: Color is a visual identification parameter only and does not affect electrical or mechanical function. Color change may impact assembly documentation and visual inspection procedures but does not alter component performance.

Q: How does the reduced contact tail length in substitute parts affect PCB design?

A: Contact tail length determines solder joint depth and mechanical support. Shorter tails (0.138" or 0.079") require PCB pad design verification to ensure adequate solder fillet formation and mechanical stability. Consult PCB layout guidelines for the selected substitute part.

Q: Do both substitute parts maintain the same voltage rating as the original?

A: IEC voltage rating decreases from 400V to 320V in both substitutes. UL voltage rating remains at 300V. Applications operating at IEC voltages above 320V require design review to confirm compatibility.

Q: Is RoHS compliance maintained across all three parts?

A: Yes. The main part 1900248 and both substitutes 1776867 and 1836858 are RoHS compliant, meeting environmental and regulatory requirements.
