Phoenix Contact 1897063 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1897063 is a 14-position terminal block header with male pins, shrouded on four sides, featuring 0.150" (3.81mm) pitch and 90° 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 1897063 is determined by strict equivalence across the following critical parameters:

Number of positions: 14
Pitch spacing: 0.150" (3.81mm)
Header type: Male pins with 4-side shrouding
Mounting configuration: 90° right-angle through-hole
Electrical ratings: 8A (IEC/UL), 250V (IEC), 300V (UL)
Housing material: Polybutylene Terephthalate (PBT)
Flammability rating: UL94 V-0
Contact mating finish: Tin

The Phoenix Contact 1827981 meets all these critical parameters and qualifies as a direct substitute. The primary difference lies in the termination style (press-fit versus solder) and minor dimensional variations in contact tail length and insulation height, which do not affect functional compatibility in applications designed for the original part.

Engineering Selection Recommendations

The Phoenix Contact 1827981 is the qualified substitute for the obsolete 1897063 based on the following engineering criteria:

Product Status: The 1827981 maintains active product status, ensuring ongoing availability and manufacturer support, whereas the 1897063 is obsolete and subject to supply discontinuation.

Compliance and Certifications: Both parts maintain equivalent electrical ratings (8A/250V IEC, 8A/300V UL) and UL94 V-0 flammability certification. The 1827981 carries ROHS3 compliance, representing current regulatory alignment compared to the RoHS Compliant designation of the original part.

Functional Equivalence: The 14-position configuration, 0.150" (3.81mm) pitch, 90° right-angle orientation, and 4-side shrouding are identical across both parts. The electrical performance and mechanical interface remain functionally equivalent.

Termination Consideration: The primary design difference is the termination method (solder versus press-fit). Applications originally designed for press-fit termination require PCB layout modification to accommodate solder termination. This is a design-level consideration, not a functional limitation.

Frequently Asked Questions (FAQ)

Q: Can the 1827981 be used as a direct drop-in replacement for the 1897063?

A: The 1827981 is functionally equivalent in electrical performance and mechanical interface. However, the termination style differs (solder versus press-fit), requiring PCB layout modification. The dimensional variations in contact tail length (0.138" versus 0.134") and insulation height (0.276" versus 0.285") are within acceptable tolerances for standard through-hole applications.

Q: What is the significance of the series designation change from COMBICON EMC to COMBICON MC?

A: The series designation reflects product line evolution within Phoenix Contact's terminal block portfolio. Both series maintain equivalent electrical and mechanical specifications for this 14-position configuration. The COMBICON MC series represents the current active product line.

Q: Are there any compliance differences between the two parts?

A: Both parts meet UL94 V-0 flammability requirements and maintain equivalent electrical ratings. The 1827981 carries ROHS3 compliance, which supersedes the RoHS Compliant designation of the 1897063, indicating alignment with current regulatory standards.

Q: What packaging considerations apply to the 1827981?

A: The 1827981 is supplied in bulk packaging, whereas the original 1897063 packaging specification is not detailed. Bulk packaging is standard for active production components and does not affect component functionality or performance.

Q: Are there any application restrictions when substituting the 1827981 for the 1897063?

A: No application restrictions exist based on electrical or mechanical parameters. The substitution is valid for all applications within the specified electrical ratings (8A/250V IEC, 8A/300V UL). PCB design modification is required only to accommodate the solder termination method.
