Phoenix Contact 1897830 Terminal Block Header – Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1897830 is a 5-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 classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

The primary reason for identifying substitute parts is the obsolete product status of the 1897830. Active equivalent models ensure continued availability, supply chain reliability, and compliance with current manufacturing standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1897830 is determined by strict alignment of the following parameters:

• Electrical Compatibility: Current rating (8A IEC), voltage rating (250V IEC), and contact mating finish (Tin) must match exactly
• Mechanical Compatibility: Number of positions (5), pitch (3.81mm), header orientation (90° right angle), mounting type (through hole), and shroud configuration (4-side) must be identical
• Material & Safety Compliance: Housing material (PBT), flammability rating (UL94 V-0), and RoHS compliance status must be equivalent or superior
• Series & Connector Family: Both parts belong to the Phoenix Contact COMBICON family, ensuring mechanical and electrical interchangeability

The substitute part 1803303 meets all these criteria, with the primary difference being termination style (solder vs. press-fit) and minor dimensional variations within acceptable tolerances.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Ongoing Supply Requirements:

The Phoenix Contact 1803303 is the recommended substitute for the obsolete 1897830. Both components share identical electrical ratings (8A at 250V IEC), mechanical form factor (5-position, 3.81mm pitch, 90° right angle), and safety certifications (UL94 V-0). The 1803303 carries active product status with superior RoHS3 compliance, ensuring long-term availability and regulatory alignment.

Termination Consideration:

The primary functional difference is termination style: the 1897830 uses press-fit termination, while the 1803303 uses solder termination. This difference requires PCB design adjustment but does not affect electrical or mechanical compatibility. The solder termination of the 1803303 is a standard manufacturing approach for through-hole terminal blocks.

Dimensional Tolerance:

Minor dimensional variations exist in contact tail length (0.138" vs. 0.134") and insulation height (0.276" vs. 0.285"). These differences fall within acceptable mechanical tolerances for connector interchangeability and do not impact functional performance or mating characteristics.

Compliance Status:

Both components meet EAR99 export classification and HTSUS 8536.69.4040 tariff coding. The 1803303 provides enhanced compliance through ROHS3 certification, making it suitable for applications requiring current regulatory standards.

Frequently Asked Questions (FAQ)

Q: Can the 1803303 directly replace the 1897830 in existing assemblies?

A: Mechanical and electrical compatibility is confirmed. The primary consideration is termination method: the 1897830 uses press-fit termination for direct PCB insertion, while the 1803303 requires solder attachment. Existing press-fit PCB footprints must be evaluated for solder pad compatibility. Both components share identical pitch (3.81mm), position count (5), and electrical ratings (8A, 250V IEC).

Q: Are there any electrical performance differences between these parts?

A: No. Both components are rated for 8A at 250V (IEC) and 8A at 300V (UL). Contact mating finish (tin), housing material (PBT), and flammability rating (UL94 V-0) are identical. Electrical performance is equivalent.

Q: What is the significance of the series designation change (COMBICON EMC vs. COMBICON MC)?

A: Both series belong to the Phoenix Contact COMBICON family and maintain mechanical and electrical interchangeability. The series designation reflects product line evolution; the MC series represents the current active product line, while the EMC series is obsolete. Functional compatibility is maintained across both series.

Q: How do the dimensional differences affect connector mating?

A: Contact tail length (0.138" vs. 0.134") and insulation height (0.276" vs. 0.285") variations are within standard mechanical tolerances for terminal block connectors. These differences do not affect mating characteristics, shroud alignment, or electrical performance. Both components maintain the same 3.81mm pitch and 90° right-angle orientation.

Q: Is the 1803303 suitable for applications requiring RoHS compliance?

A: Yes. The 1803303 carries ROHS3 certification, meeting current RoHS Directive requirements. The 1897830 is RoHS Compliant but does not specify ROHS3 status. For new designs and applications requiring current regulatory alignment, the 1803303 is the appropriate selection.

Q: What packaging considerations apply to the 1803303?

A: The 1803303 is supplied in bulk packaging, whereas the 1897830 packaging is not specified. Bulk packaging is standard for terminal block components and does not affect component functionality or performance.
