Phoenix Contact 1899663 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1899663 is a 7-position terminal block header with male pins, shrouded on four sides, featuring a 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 design support and procurement continuity. The COMBICON EMSTB series part utilizes press-fit termination and is rated for 12A (IEC) / 15A (UL) operation at 400V (IEC) / 300V (UL).

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1899663 is determined by the following critical parameters:

• Electrical Compatibility: Current and voltage ratings must meet or exceed the original specification (12A IEC / 15A UL at 400V IEC / 300V UL)
• Physical Compatibility: 7-position configuration, 0.200" (5.08mm) pitch, 90° right-angle orientation, through-hole mounting, and shrouded (4-side) male pin design
• Mechanical Compatibility: Mating and mounting flange features, UL94 V-0 flammability rating, and equivalent insulation height (0.339")
• Termination Method: Press-fit or solder termination are both acceptable for through-hole applications

The two substitute parts identified (1776553 and 1792672) maintain electrical and mechanical compatibility while offering active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1776553 (COMBICON MSTB Series)

Part 1776553 is the primary substitute for the obsolete 1899663. Both components maintain identical electrical ratings (12A IEC / 15A UL, 400V IEC / 300V UL), physical configuration (7-position, 5.08mm pitch, 90° right-angle), and mechanical features (shrouded male pins, through-hole mounting, UL94 V-0 rating). The 1776553 features active product status and ROHS3 compliance, providing superior long-term availability and regulatory alignment. The termination method differs (solder versus press-fit), which is compatible with standard through-hole assembly processes. Contact tail length is reduced (0.138" versus 0.165"), which may require PCB layout verification for existing designs.

Phoenix Contact 1792672 (COMBICON CC Series)

Part 1792672 serves as a secondary substitute with active product status and equivalent mechanical compatibility. This component maintains the 7-position, 5.08mm pitch, 90° right-angle configuration and UL94 V-0 flammability rating. The IEC electrical ratings remain identical (12A, 400V), but the UL current rating is reduced to 10A (versus 15A on the original). This part is suitable for applications where UL ratings do not exceed 10A. The housing material differs (Liquid Crystal Polymer versus Polybutylene Terephthalate), and contact tail length is significantly shorter (0.102"), requiring PCB layout assessment. Color is black rather than green.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1776553 directly replace 1899663 in existing designs?

A: Electrical and mechanical compatibility is confirmed. The primary design consideration is the reduced contact tail length (0.138" versus 0.165"), which may affect PCB pad spacing. Termination method changes from press-fit to solder, requiring assembly process adjustment. Layout verification is necessary before implementation.

Q: What is the significance of the termination method difference?

A: The original 1899663 uses press-fit termination, while substitutes 1776553 and 1792672 use solder termination. Both methods are standard for through-hole terminal block headers. Press-fit provides tool-less installation; solder requires reflow or wave soldering processes. Component functionality and electrical performance are equivalent.

Q: Is Phoenix Contact 1792672 suitable for all applications requiring the 1899663?

A: Part 1792672 is suitable for applications where UL current ratings do not exceed 10A. The IEC rating of 12A at 400V matches the original specification. The reduced contact tail length (0.102") and different housing material (LCP versus PBT) require PCB layout verification. This part is recommended as a secondary option when 1776553 is unavailable.

Q: What compliance certifications apply to the substitute parts?

A: Both substitute parts maintain UL94 V-0 flammability rating and MSL 1 (Unlimited) moisture sensitivity classification. Part 1776553 carries ROHS3 compliance; part 1792672 carries RoHS compliance. Both are classified as EAR99 for export control purposes. All three parts share the same HTSUS code (8536.69.4040).

Q: How do housing material differences affect component selection?

A: The original 1899663 and substitute 1776553 use Polybutylene Terephthalate (PBT); substitute 1792672 uses Liquid Crystal Polymer (LCP). Both materials meet UL94 V-0 flammability requirements. LCP offers superior dimensional stability and chemical resistance; PBT provides established thermal performance. Material selection should align with application environmental conditions and thermal cycling requirements.

Q: Are there inventory considerations for these substitutes?

A: All three parts are listed as in-stock: 1899663 (1091 pcs), 1776553 (979 pcs), and 1792672 (990 pcs). However, the original 1899663 is obsolete and inventory will not be replenished. Substitutes 1776553 and 1792672 have active product status, ensuring continued availability for future procurement.
