Phoenix Contact 1897005 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1897005 is an 8-position terminal block header with male pins, shrouded on 4 sides, featuring 0.150" (3.81mm) pitch and 90° right-angle orientation for through-hole mounting. This component is classified as obsolete, making identification of suitable substitutes essential for ongoing system maintenance and new design implementations where legacy compatibility is not required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1897005 is determined by strict equivalence across the following critical parameters:

• Electrical Compatibility: Identical current rating (8A IEC/UL) and voltage rating (250V IEC / 300V UL)
• Mechanical Compatibility: Matching number of positions (8), pitch (0.150" / 3.81mm), header orientation (90° right angle), and mounting type (through hole)
• Physical Form Factor: Identical connector type (header with male pins, shrouded 4-side), housing material (PBT), and flammability rating (UL94 V-0)
• Regulatory Compliance: RoHS compliance status

The Phoenix Contact 1827923 qualifies as a direct substitute based on these parameters. While termination style differs (press-fit vs. solder) and minor dimensional variations exist in contact tail length and insulation height, these differences do not affect functional interchangeability in applications where the electrical and mechanical specifications are met.

Parameter Comparison

Engineering Selection Recommendations

For New Designs: The Phoenix Contact 1827923 is the recommended selection. This part is active in production status with superior inventory availability (4798 units vs. 1024 units) and meets enhanced RoHS3 compliance requirements. The solder termination style provides standard PCB assembly compatibility.

For Legacy System Maintenance: The Phoenix Contact 1897005 remains available in stock. However, given its obsolete status, procurement should prioritize the 1827923 substitute where design modifications to accommodate solder termination are feasible. The minor dimensional differences in contact tail length (0.138" vs. 0.134") and insulation height (0.276" vs. 0.285") do not impact electrical performance or mechanical fit in standard through-hole applications.

Compliance Consideration: Both parts maintain UL94 V-0 flammability rating and tin contact mating finish. The 1827923 provides enhanced regulatory coverage through ROHS3 compliance and REACH unaffected status, making it the preferred choice for applications subject to evolving environmental regulations.

Frequently Asked Questions (FAQ)

Q: Can the 1827923 directly replace the 1897005 in existing PCB designs?

A: Functional replacement is supported based on electrical and mechanical equivalence. The primary design consideration is termination method: the 1897005 uses press-fit termination while the 1827923 uses solder termination. PCB pad design and assembly process must accommodate solder termination. Contact tail length and insulation height differences are within acceptable tolerances for standard through-hole mounting.

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

A: Series designation reflects product line evolution within Phoenix Contact's terminal block portfolio. Both series maintain identical electrical ratings, mechanical form factors, and compliance certifications. The series change reflects manufacturing updates and does not affect interchangeability for the specified electrical and mechanical parameters.

Q: Are there any restrictions on using the 1827923 in high-reliability applications?

A: Both parts meet UL94 V-0 flammability requirements and maintain 8A/250V (IEC) and 8A/300V (UL) ratings. Selection should be based on application-specific requirements for termination method (solder vs. press-fit) and compliance certifications. The 1827923 provides enhanced regulatory coverage through ROHS3 compliance.

Q: What is the impact of the contact tail length difference (0.138" vs. 0.134")?

A: The 0.004" (0.10mm) difference in contact tail length is within standard manufacturing tolerances for through-hole terminal blocks and does not affect PCB pad engagement or electrical performance in standard applications.

Q: Why is the 1897005 classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. The 1827923 represents the current production equivalent within Phoenix Contact's COMBICON terminal block family, offering improved compliance certifications and manufacturing continuity.
