Phoenix Contact 1897872 Terminal Block Header – Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1897872 is a 9-position terminal block header with male pins, shrouded on four 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 functionally equivalent alternatives essential for ongoing system support and procurement planning.

The COMBICON EMC series part is no longer in active production. Locating compatible substitute components ensures design continuity and system reliability for applications requiring this terminal block configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1897872 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Number of positions: 9
• Pitch: 0.150" (3.81mm)
• Header orientation: 90°, Right Angle
• Type: Header, Male Pins, Shrouded (4 Side)
• Mounting type: Through Hole
• Current rating (IEC): 8A
• Voltage rating (IEC): 250V
• Current rating (UL): 8A
• Voltage rating (UL): 300V
• Housing material: Polybutylene Terephthalate (PBT)
• Flammability rating: UL94 V-0

Allowable Variations:

• Termination style (Press-Fit vs. Solder)
• Contact tail length (within mechanical tolerance)
• Insulation height (within mechanical tolerance)
• Product status (Active vs. Obsolete)
• RoHS certification version (RoHS Compliant vs. ROHS3 Compliant)

The Phoenix Contact 1803345 meets all mandatory matching parameters and qualifies as a direct functional substitute despite differences in termination style and minor dimensional variations.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1803345 is the qualified substitute for the obsolete 1897872 terminal block header. Both components share identical electrical ratings, mechanical form factor, and compliance certifications.

Selection Basis:

The 1803345 is an active production component within the COMBICON MC series, ensuring long-term availability and supply chain stability. The part maintains full electrical compatibility with the original 1897872, including current and voltage ratings under both IEC and UL standards.

The primary difference is termination style: the 1897872 uses press-fit termination, while the 1803345 uses solder termination. This distinction affects assembly methodology but does not alter electrical or mechanical performance. Minor variations in contact tail length (0.138" vs. 0.134") and insulation height (0.276" vs. 0.285") fall within acceptable mechanical tolerances for through-hole mounting applications.

Both components meet UL94 V-0 flammability requirements and maintain equivalent moisture sensitivity levels. The 1803345 carries ROHS3 compliance, representing current regulatory alignment compared to the earlier RoHS Compliant designation of the 1897872.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1803345 directly replace the 1897872 in existing designs?

A: Yes. The 1803345 matches all critical electrical and mechanical parameters of the 1897872. The primary consideration is termination method: the 1803345 requires solder attachment rather than press-fit insertion. PCB layout and assembly processes must accommodate solder termination.

Q: What is the significance of the different termination styles?

A: Press-fit termination (1897872) allows mechanical insertion into plated through-holes without soldering. Solder termination (1803345) requires traditional wave or reflow soldering. Both methods achieve equivalent electrical and mechanical connections when properly executed.

Q: Are the dimensional differences between the two parts significant?

A: The contact tail length difference (0.138" vs. 0.134") and insulation height difference (0.276" vs. 0.285") are minor and fall within standard mechanical tolerances for through-hole terminal block applications. These variations do not affect PCB mounting or electrical performance.

Q: Does the ROHS3 compliance of the 1803345 affect compatibility?

A: No. ROHS3 compliance represents an updated regulatory certification and does not introduce incompatibility. The 1803345 is fully compatible with systems designed for the RoHS Compliant 1897872.

Q: What is the inventory status of these parts?

A: The 1897872 (obsolete) has 902 pieces in stock. The 1803345 (active production) has 3034 pieces in stock, providing superior long-term availability.

Q: Are both parts suitable for the same electrical applications?

A: Yes. Both components are rated for 8A at 250V (IEC) and 8A at 300V (UL), with identical UL94 V-0 flammability ratings and PBT housing material. Electrical performance is equivalent.
