Phoenix Contact 1899786 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1899786 is a 19-position terminal block header with male pins, shrouded on four sides, featuring 0.200" (5.08mm) pitch and right-angle through-hole mounting. This component is part of the COMBICON EMSTB series and is classified as obsolete. Due to its obsolete status, equivalent substitute parts from Phoenix Contact's active product lines are available to maintain design compatibility and ensure continued supply chain availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1899786 is determined by the following critical parameters:

• Position Count & Pitch: All substitute parts must have 19 positions with 0.200" (5.08mm) pitch spacing
• Header Type & Orientation: Male pins, shrouded (4 side), 90° right-angle configuration required
• Mounting Method: Through-hole mounting only
• Electrical Ratings: Minimum IEC current rating of 12A and IEC voltage rating of 400V
• Compliance: RoHS compliance and UL94 V-0 flammability rating required
• Termination Style: Press-fit or solder termination acceptable based on application requirements

The two substitute parts identified—Phoenix Contact 1776676 and 1827582—meet these core substitution criteria while offering active product status and improved supply availability.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1776676 is the primary substitute for the 1899786. Both components share identical electrical ratings (12A IEC, 400V IEC, 15A UL, 300V UL), housing material (PBT), and mechanical dimensions. The 1776676 differs only in termination style (solder versus press-fit) and is classified as active product status, ensuring long-term availability. The shorter contact tail length (0.138" versus 0.165") requires PCB layout verification for through-hole depth compatibility.

Phoenix Contact 1827582 serves as a secondary substitute with active product status. This component maintains the same position count, pitch, and header configuration. Key differences include reduced IEC voltage rating (320V versus 400V), alternative housing material (LCP versus PBT), and significantly shorter contact tail length (0.102"). The 1827582 is suitable only for applications where the 320V IEC rating meets electrical requirements and where the reduced contact tail length accommodates PCB design constraints.

Both substitute parts carry RoHS compliance and UL94 V-0 flammability certification, matching the original component's regulatory status.

Frequently Asked Questions (FAQ)

Q: Can the 1776676 directly replace the 1899786 in existing designs?

A: The 1776676 maintains electrical and mechanical compatibility with the 1899786 across all critical parameters. The primary design consideration is termination method: the 1776676 uses solder termination instead of press-fit. PCB layout must accommodate the shorter contact tail length (0.138" versus 0.165"). Electrical performance remains equivalent under specified operating conditions.

Q: What is the key difference between the 1776676 and 1827582 substitutes?

A: The 1776676 maintains the original 400V IEC rating and PBT housing material with a contact tail length of 0.138". The 1827582 reduces the IEC voltage rating to 320V, uses LCP housing material, and has a significantly shorter contact tail length of 0.102". Selection depends on application voltage requirements and PCB through-hole depth specifications.

Q: Are all substitute parts RoHS compliant?

A: Yes. Both the 1776676 and 1827582 are RoHS compliant and carry UL94 V-0 flammability certification, matching the regulatory status of the original 1899786 component.

Q: Why is the 1899786 classified as obsolete?

A: The 1899786 is obsolete and no longer in active production. Phoenix Contact has transitioned to the COMBICON MSTB and COMBICON CC series for equivalent functionality. The substitute parts provide continued design compatibility while ensuring supply chain continuity.

Q: Does contact tail length affect electrical performance?

A: Contact tail length does not affect electrical performance. It is a mechanical specification that determines PCB through-hole insertion depth. Designs must verify that the shorter tail lengths of substitute parts (0.138" or 0.102") are compatible with existing PCB hole depth specifications.

Q: Can the 1827582 be used in applications requiring 400V IEC operation?

A: No. The 1827582 is rated for 320V IEC maximum. Applications requiring 400V IEC operation must use either the original 1899786 or the 1776676 substitute.
