Phoenix Contact 1899650 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1899650 is a 6-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 active equivalent parts essential for ongoing production and maintenance applications. 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 1899650 is determined by the following critical parameters that must remain constant across equivalent parts:

Mandatory Matching Parameters:

• Number of positions: 6
• Pitch: 0.200" (5.08mm)
• Header orientation: 90°, Right Angle
• Type: Header, Male Pins, Shrouded (4 Side)
• Mounting type: Through Hole
• Current rating (IEC): 12A minimum
• Voltage rating (IEC): 400V minimum
• Flammability rating: UL94 V-0
• Contact mating finish: Tin

Variable Parameters Allowing Substitution:

• Termination style (Press-Fit vs. Solder)
• Series designation (COMBICON EMSTB, MSTB, CC)
• Contact tail length
• Housing material (PBT vs. LCP)
• Housing color
• Product status (Obsolete vs. Active)
• RoHS compliance version

The two identified substitute parts (1776540 and 1792669) maintain all mandatory parameters while differing in termination methodology and housing specifications, enabling functional equivalence in terminal block header applications.

Parameter Comparison

Engineering Selection Recommendations

1776540 (COMBICON MSTB Series): This substitute part is the primary equivalent for the obsolete 1899650. Both components share identical electrical ratings (12A IEC, 15A UL) and mechanical dimensions. The primary difference is termination methodology: 1776540 uses solder termination instead of press-fit. This part carries active product status and ROHS3 compliance, making it suitable for new designs and ongoing production. The contact tail length is reduced to 0.138" (4.60mm) compared to the original 0.165" (4.19mm), requiring PCB layout verification for through-hole depth compatibility.

1792669 (COMBICON CC Series): This alternative substitute maintains the same 6-position, 5.08mm pitch configuration and shares identical IEC ratings (12A, 400V). However, the UL current rating is reduced to 10A compared to the original 15A specification. The housing material differs (Liquid Crystal Polymer vs. PBT), and the contact tail length is significantly shorter at 0.102" (2.60mm). This part is suitable only for applications where the 10A UL rating is sufficient and where the reduced contact tail length accommodates PCB design constraints. The black housing color differs from the original green specification.

Both substitute parts maintain the mandatory electrical and mechanical parameters required for functional equivalence in terminal block header applications. Selection between 1776540 and 1792669 depends on specific application current requirements, PCB layout constraints, and housing material compatibility.

Frequently Asked Questions (FAQ)

Q: Can 1776540 directly replace 1899650 in existing designs?

A: 1776540 maintains electrical equivalence (12A IEC, 15A UL) and mechanical compatibility (6 positions, 5.08mm pitch, 90° orientation). The primary design consideration is the reduced contact tail length (0.138" vs. 0.165"), which requires verification that PCB through-hole depth accommodates the shorter tail. Termination methodology differs (solder vs. press-fit), necessitating assembly process adjustment.

Q: What are the key differences between 1776540 and 1792669?

A: Both parts are functionally equivalent 6-position, 5.08mm pitch terminal block headers. 1776540 maintains the full 15A UL rating and uses PBT housing material. 1792669 reduces the UL rating to 10A, uses LCP housing material, and features a significantly shorter contact tail (0.102" vs. 0.138"). Selection depends on application current requirements and PCB layout constraints.

Q: Is the reduced contact tail length of 1792669 a compatibility issue?

A: The contact tail length reduction from 0.165" (original) to 0.102" (1792669) affects PCB through-hole depth requirements. This part is suitable only for applications where the shorter tail length accommodates existing PCB design or where PCB modification is feasible. 1776540 provides an intermediate option with 0.138" tail length.

Q: Are there compliance differences between the substitute parts?

A: 1776540 carries ROHS3 compliance, while both the original 1899650 and 1792669 carry standard RoHS compliance. All three parts maintain UL94 V-0 flammability rating and EAR99 export classification. Moisture sensitivity level is identical (MSL 1, Unlimited) across all parts.

Q: Can 1792669 be used in applications requiring 15A UL rating?

A: No. 1792669 is rated for 10A UL maximum, making it unsuitable for applications requiring the original 15A UL specification. 1776540 maintains the full 15A UL rating and is the appropriate substitute for current-critical applications.

Q: What assembly process changes are required when switching from 1899650 to 1776540?

A: The primary change is termination methodology: 1899650 uses press-fit termination, while 1776540 requires solder termination. This necessitates assembly process modification from press-fit insertion to solder reflow or wave soldering, depending on manufacturing capability.
