Phoenix Contact 1899689 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1899689 is a 9-position terminal block header with male pins, shrouded on four sides, featuring 0.200" (5.08mm) 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 COMBICON EMSTB series part utilizes press-fit termination and is suitable for applications requiring 12A (IEC) or 15A (UL) current handling at 400V (IEC) or 300V (UL) voltage ratings. Due to its obsolete status, equivalent substitute parts from active product lines are necessary to ensure supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1899689 is determined by strict alignment with the following electrical and mechanical parameters:

• Electrical Compatibility: Current and voltage ratings must meet or exceed IEC 12A/400V and UL 15A/300V specifications
• Physical Compatibility: 9 positions, 0.200" (5.08mm) pitch, 90° right-angle orientation, through-hole mounting, and shrouded (4-side) male pin configuration
• Mechanical Interface: Mating and mounting flange presence, tin contact mating finish, and UL94 V-0 flammability rating
• Termination Consideration: Substitute parts may employ different termination styles (press-fit vs. solder) provided mechanical and electrical performance remains equivalent

The two identified substitutes—Phoenix Contact 1776579 and 1792698—satisfy these core parameters while offering active product status and improved supply availability.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1776579 is the primary substitute for the obsolete 1899689. Both parts maintain identical electrical ratings (12A IEC, 15A UL) and physical dimensions, with matching PBT housing material and green color. The transition from press-fit to solder termination requires PCB design modification but does not affect electrical or mechanical compatibility. This part carries active product status and ROHS3 compliance, ensuring long-term availability.

Phoenix Contact 1792698 serves as an alternative substitute with full IEC compliance (12A/400V) but reduced UL current rating (10A vs. 15A). The housing material differs (Liquid Crystal Polymer instead of PBT) and color is black rather than green. The significantly shorter contact tail length (0.102" vs. 0.165") may require PCB layout adjustment. This part is suitable only for applications where the 10A UL rating is acceptable and where housing material substitution does not conflict with design specifications.

Selection between 1776579 and 1792698 depends on application voltage/current requirements and PCB design constraints. For applications requiring full 15A UL rating, 1776579 is the appropriate choice. For applications operating within 10A UL limits with flexible housing material requirements, 1792698 offers an alternative.

Frequently Asked Questions (FAQ)

Q: Can the 1899689 be directly replaced with the 1776579 without PCB modification?

A: Electrical and mechanical compatibility is maintained. However, termination style differs (press-fit vs. solder), requiring PCB pad design changes. Contact tail length is shorter (0.138" vs. 0.165"), which may affect PCB layout depending on trace routing and component spacing.

Q: What is the significance of the contact tail length difference between these parts?

A: Contact tail length determines the depth of solder joint or press-fit engagement on the PCB. The 1899689 has 0.165" tails, while 1776579 has 0.138" and 1792698 has 0.102". Shorter tails require PCB pad depth adjustment and may affect mechanical stability in high-vibration environments.

Q: Is the 1792698 suitable for all applications using the 1899689?

A: The 1792698 is suitable only for applications where UL current rating of 10A is acceptable. The original 1899689 supports 15A UL. Additionally, housing material differs (LCP vs. PBT), which may affect thermal performance and chemical resistance depending on the application environment.

Q: What compliance differences exist between these parts?

A: The 1899689 is RoHS Compliant. The 1776579 is ROHS3 Compliant, representing a more recent regulatory standard. The 1792698 is RoHS Compliant. All three parts carry UL94 V-0 flammability rating and MSL 1 (Unlimited) moisture sensitivity rating.

Q: Are there any color or visual identification differences that affect functionality?

A: The 1899689 and 1776579 are green; the 1792698 is black. Color is a visual identifier only and does not affect electrical or mechanical performance. However, color consistency may be important for system documentation or maintenance procedures.

Q: What inventory status should influence part selection?

A: The 1899689 is obsolete with 790 units in stock. The 1776579 has 1122 units available, and the 1792698 has 1107 units available. For new designs or long-term production, selection should prioritize active product status (1776579 or 1792698) to ensure sustained supply chain availability.
