Phoenix Contact 1899676 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1899676 is an 8-position terminal block header with male pins, shrouded design, and 90° right-angle orientation. This component features a 0.200" (5.08mm) pitch and press-fit termination style, designed for through-hole mounting applications. The part is classified as obsolete, making identification of equivalent substitute components essential for ongoing system maintenance and new design implementations where this series is specified.

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1899676 is determined by the following critical parameters:

Electrical Compatibility: Current rating (IEC: 12A minimum), voltage rating (IEC: 400V minimum), and contact mating finish (Tin)
Mechanical Compatibility: 8 positions, 0.200" (5.08mm) pitch, 90° right-angle orientation, male pins with 4-side shrouded design, through-hole mounting
Material & Safety: UL94 V-0 flammability rating, RoHS compliance status
Dimensional Compatibility: Insulation height of 0.339" (8.61mm)

The identified substitute parts (1776566 and 1792685) maintain these core electrical and mechanical parameters while differing in termination style (solder vs. press-fit), series designation, and specific contact tail lengths.

Engineering Selection Recommendations

1776566 (COMBICON MSTB Series)

This substitute maintains full electrical compatibility with the main part across both IEC and UL standards. The primary difference is termination style: solder-based rather than press-fit. Both parts share identical pitch, position count, orientation, and insulation height. The 1776566 is currently in active production status with higher inventory availability (2074 units). Housing material remains PBT with UL94 V-0 rating. Contact tail length is shorter (0.138" vs. 0.165"), which may require PCB layout verification for through-hole mounting depth. RoHS3 compliance exceeds the original RoHS requirement.

1792685 (COMBICON CC Series)

This substitute meets core electrical specifications for IEC ratings (12A/400V) but has a reduced UL current rating of 10A compared to the main part's 15A. Housing material differs (LCP instead of PBT), though both maintain UL94 V-0 flammability rating. Contact tail length is significantly shorter (0.102" vs. 0.165"), requiring PCB design verification. Color is black rather than green. This part is active in production with moderate inventory (639 units). Suitable for applications where UL 10A rating is sufficient and PCB mounting depth accommodates the shorter tail length.

Frequently Asked Questions (FAQ)

Q: Can 1776566 be used as a direct replacement for 1899676 in existing PCB designs?

A: Mechanical compatibility exists for pitch, position count, and orientation. However, termination style differs (solder vs. press-fit), requiring PCB pad redesign. Contact tail length is 0.027" shorter, which may affect mounting depth. Verify PCB layout before implementation.

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

A: Both 1776566 and 1792685 use solder termination. The 1792685 has a lower UL current rating (10A vs. 15A), different housing material (LCP vs. PBT), and significantly shorter contact tail (0.102" vs. 0.138"). Select based on electrical requirements and PCB mounting constraints.

Q: Is the 1792685 suitable for high-current applications?

A: The 1792685 maintains the IEC rating of 12A but has a reduced UL rating of 10A. For applications requiring 15A UL compliance, use 1776566 instead.

Q: Do all three parts have the same insulation height?

A: Yes. All three parts maintain an insulation height of 0.339" (8.61mm), ensuring consistent mating interface dimensions.

Q: Are there packaging differences between these parts?

A: The main part (1899676) is listed as obsolete with unspecified packaging. Both substitutes (1776566 and 1792685) are supplied in bulk packaging.

Q: What compliance certifications apply to these substitutes?

A: Both 1776566 and 1792685 are ROHS3 compliant and carry UL94 V-0 flammability ratings. Both are classified as EAR99 for export control purposes.
