Phoenix Contact 1897050 Terminal Block Header – Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1897050 is a 13-position terminal block header with male pins, shrouded on four sides, designed for 0.150" (3.81mm) pitch right-angle through-hole mounting. This component is part of the COMBICON EMC series and is classified as obsolete. Due to its obsolete status, identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs or system maintenance.

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1897050 is determined by strict alignment of the following critical parameters:

Electrical Specifications: Current rating (8A IEC/UL), voltage rating (250V IEC / 300V UL)
Physical Configuration: 13 positions, 0.150" (3.81mm) pitch, right-angle orientation, through-hole mounting
Connector Type: Male pins with four-side shrouding
Material & Compliance: PBT housing with UL94 V-0 flammability rating, RoHS compliance

The substitute part Phoenix Contact 1827978 meets all these critical parameters. The primary differences are the termination style (solder vs. press-fit), series designation (COMBICON MC vs. COMBICON EMC), and minor dimensional variations in contact tail length and insulation height. The substitute part is classified as active and carries ROHS3 compliance with REACH unaffected status.

Engineering Selection Recommendations

The Phoenix Contact 1827978 is a direct functional substitute for the obsolete 1897050. Both components share identical electrical ratings, physical positioning, and core mechanical specifications. The substitute part carries active product status, ensuring long-term availability and supply chain stability.

The primary distinction is the termination method: the 1897050 uses press-fit termination, while the 1827978 requires solder termination. This difference necessitates PCB design modification to accommodate solder pads instead of press-fit holes. The substitute part's ROHS3 compliance and REACH unaffected status provide enhanced regulatory alignment for current manufacturing standards.

Minor dimensional variations in contact tail length (0.004" difference) and insulation height (0.009" difference) fall within acceptable tolerances for standard through-hole PCB applications and do not affect electrical performance or mechanical fit within standard connector housings.

Frequently Asked Questions (FAQ)

Q: Can the 1827978 directly replace the 1897050 without PCB modification?

A: No. The 1897050 uses press-fit termination, while the 1827978 requires solder termination. PCB design changes are necessary to accommodate the different termination method.

Q: Are the electrical specifications identical between these parts?

A: Yes. Both components are rated for 8A (IEC/UL), 250V (IEC), and 300V (UL), with identical pitch, position count, and connector configuration.

Q: What is the significance of the ROHS3 compliance on the substitute part?

A: ROHS3 compliance indicates adherence to the current Restriction of Hazardous Substances directive. The substitute part meets modern regulatory requirements, whereas the main part carries standard RoHS compliance.

Q: Do the dimensional differences affect compatibility with existing connector housings?

A: The contact tail length difference (0.004") and insulation height difference (0.009") are minor and do not affect standard connector housing compatibility or electrical performance.

Q: Why is the main part classified as obsolete?

A: The 1897050 is part of the COMBICON EMC series, which has been superseded by the active COMBICON MC series. The 1827978 represents the current-generation equivalent.

Q: Is the substitute part available in the same packaging as the main part?

A: The 1827978 is supplied in bulk packaging, whereas the main part packaging is not specified. Confirm packaging requirements with your procurement department.
