Phoenix Contact 1899621 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1899621 is a 3-position terminal block header with male pins, shrouded design, and 0.200" (5.08mm) pitch in 90° right-angle through-hole configuration. This component belongs to the COMBICON EMSTB series and is classified as obsolete. Due to its obsolete status, identifying equivalent substitute parts from active product lines is essential for ongoing design support, procurement continuity, and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1899621 is determined by the following critical parameters:

• Electrical Compatibility: Current and voltage ratings must meet or exceed the original specification (IEC: 12A/400V; UL: 15A/300V)
• Physical Compatibility: Number of positions (3), pitch (0.200"/5.08mm), header orientation (90° right angle), and mounting type (through hole) must be identical
• Mechanical Compatibility: Shrouded (4 side) design and mating/mounting flange features must be maintained
• Material & Safety Compliance: UL94 V-0 flammability rating and RoHS compliance required

The two substitute parts identified—Phoenix Contact 1776511 and 1792630—share identical electrical ratings, physical dimensions, and core mechanical features with the original 1899621. Both are active products from current COMBICON series lines, providing long-term availability and design continuity.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1776511 is the primary substitute for the 1899621. Both components maintain identical electrical ratings (IEC: 12A/400V; UL: 15A/300V), physical dimensions, and core mechanical specifications. The 1776511 is an active product in the COMBICON MSTB series with ROHS3 compliance, ensuring long-term availability and regulatory support. The primary difference is termination style: the original uses press-fit termination, while the 1776511 uses solder termination. This change requires PCB design modification but does not affect electrical or mechanical compatibility.

Phoenix Contact 1792630 is a secondary substitute from the COMBICON CC series. It maintains the same physical footprint, pitch, and IEC electrical ratings as the original. However, the UL current rating is reduced to 10A (versus 15A on the original), making it suitable only for applications where UL compliance at 10A or below is acceptable. The housing material differs (Liquid Crystal Polymer instead of PBT), and the contact tail length is shorter (0.102" versus 0.165"), requiring PCB layout verification. This part is ROHS3 compliant and active.

For new designs or direct replacement applications, 1776511 is the recommended substitute. For applications with lower current requirements or where housing material alternatives are acceptable, 1792630 provides an additional option.

Frequently Asked Questions (FAQ)

Q: Can the 1899621 be directly replaced with the 1776511 without PCB modification?

A: No. The primary difference is termination style. The 1899621 uses press-fit termination, while the 1776511 uses solder termination. PCB pad design and assembly process must be updated accordingly. However, electrical and mechanical compatibility are maintained.

Q: What is the difference between the 1776511 and 1792630 substitutes?

A: Both are active alternatives, but they differ in three key areas: (1) UL current rating—1776511 maintains 15A, while 1792630 is rated 10A; (2) housing material—1776511 uses PBT, 1792630 uses LCP; (3) contact tail length—1776511 is 0.138", 1792630 is 0.102". The 1776511 is the closer electrical match.

Q: Is the 1792630 suitable for my application if I only need 10A UL compliance?

A: Yes, provided your application does not exceed 10A at UL voltage levels (300V). The IEC ratings remain 12A/400V for all three parts. Verify that the shorter contact tail length (0.102" versus 0.165" on the original) accommodates your PCB design.

Q: Are all three parts RoHS compliant?

A: Yes. The original 1899621 is RoHS Compliant. Both substitutes (1776511 and 1792630) are ROHS3 Compliant, which represents an updated compliance standard and is fully compatible with RoHS requirements.

Q: What is the impact of different housing materials (PBT versus LCP)?

A: Both materials meet UL94 V-0 flammability requirements. PBT (used in 1899621 and 1776511) and LCP (used in 1792630) have different thermal and mechanical properties. LCP offers superior thermal performance but may have different dimensional stability. Verify material compatibility with your operating environment and mechanical stress conditions.

Q: Can I use the 1792630 if my design requires the original green color?

A: No. The 1792630 is supplied in black, while the original 1899621 and substitute 1776511 are green. If color coding is functionally required, the 1776511 is the appropriate choice.

Q: What inventory levels are available for these parts?

A: The original 1899621 has 823 pcs in stock (obsolete status). The 1776511 has 1424 pcs available, and the 1792630 has 992 pcs available. Both substitutes are active products with ongoing supply.
