Phoenix Contact 1899773 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1899773 is an 18-position terminal block header from the COMBICON EMSTB series, designed for 0.200" (5.08mm) pitch applications with right-angle through-hole mounting. This component features male pins with four-sided shrouding and is rated for 12A (IEC) / 15A (UL) operation at 400V (IEC) / 300V (UL). The part is currently obsolete, making identification of compatible substitutes essential for ongoing maintenance and new designs requiring equivalent functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1899773 is determined by the following critical parameters:

• Position Count & Pitch: All substitutes must maintain 18 positions at 0.200" (5.08mm) pitch to ensure mechanical and electrical compatibility with mating connectors.
• Header Type & Orientation: Right-angle through-hole mounting with male pins and four-sided shrouding is required for form-factor compatibility.
• Electrical Ratings: Minimum current and voltage ratings must meet or exceed IEC 12A/400V and UL 15A/300V specifications.
• Mounting Interface: Through-hole termination is mandatory for PCB integration.
• Compliance: RoHS compliance and UL94 V-0 flammability rating are required for regulatory alignment.

The two identified substitutes (1776663 and 1827579) satisfy these core parameters while differing in termination style (solder vs. press-fit), housing material composition, 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

Phoenix Contact 1776663 is the primary substitute for the 1899773. Both parts share identical electrical ratings (12A IEC / 15A UL, 400V IEC / 300V UL), matching housing material (PBT), and equivalent flammability certification (UL94 V-0). The transition from press-fit to solder termination represents the primary design difference. Part 1776663 maintains active product status and full RoHS compliance, making it suitable for direct replacement in applications where solder termination is acceptable.

Phoenix Contact 1827579 serves as a secondary substitute with comparable electrical performance (12A IEC / 16A UL, 320V IEC / 300V UL). This part utilizes Liquid Crystal Polymer (LCP) housing material instead of PBT and employs solder termination. The reduced IEC voltage rating (320V vs. 400V) requires evaluation against specific application voltage requirements. Part 1827579 maintains active status and full RoHS compliance.

Both substitutes are suitable for applications requiring equivalent 18-position, 5.08mm pitch terminal block headers with through-hole mounting. Selection between 1776663 and 1827579 depends on housing material preference, voltage margin requirements, and termination method compatibility with the target PCB assembly process.

Frequently Asked Questions (FAQ)

Q: Can the 1899773 be directly replaced with either substitute part?

A: Direct replacement is possible with 1776663 or 1827579, provided the PCB assembly process accommodates the termination method change. The 1899773 uses press-fit termination, while both substitutes employ solder termination. Mechanical and electrical interfaces remain compatible.

Q: What is the primary difference between the two substitute parts?

A: The 1776663 and 1827579 differ in housing material (PBT vs. LCP), IEC voltage rating (400V vs. 320V), and color (green vs. black). Both maintain identical position count, pitch, and through-hole mounting configuration. Selection depends on application voltage requirements and material specifications.

Q: Are there any compliance or certification differences between the main part and substitutes?

A: All three parts are RoHS compliant and carry UL94 V-0 flammability ratings. No compliance gaps exist between the 1899773 and either substitute. Both substitutes maintain active product status, ensuring ongoing availability and support.

Q: Does the change from press-fit to solder termination affect electrical performance?

A: No. Termination method does not affect electrical ratings or performance characteristics. The change impacts only the assembly process and PCB integration method. Both solder and press-fit terminations achieve equivalent electrical connectivity when properly executed.

Q: Which substitute is recommended for new designs?

A: The 1776663 is recommended for new designs due to its identical electrical ratings to the original part (12A IEC / 15A UL, 400V IEC / 300V UL) and matching PBT housing material. The 1827579 is suitable when LCP material properties or the higher UL current rating (16A) provide specific design advantages.
