Phoenix Contact 1897924 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1897924 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 classified as obsolete and operates at 8A (IEC/UL) and 250V (IEC) / 300V (UL). Due to its obsolete product status, identifying equivalent substitute parts is essential for ongoing system maintenance, repairs, and new designs requiring compatible interconnection solutions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1897924 is determined by the following critical parameters:

• Electrical Compatibility: Current rating (8A IEC/UL), voltage rating (250V IEC / 300V UL), and contact mating finish (Tin)
• Mechanical Compatibility: 14 positions, 0.150" (3.81mm) pitch, 90° right-angle orientation, through-hole mounting, and shrouded (4-side) housing
• Material & Safety Compliance: Polybutylene Terephthalate (PBT) housing, UL94 V-0 flammability rating, and RoHS compliance status
• Functional Equivalence: Single-level header configuration with male pins

The Phoenix Contact 1803390 qualifies as a direct substitute based on matching electrical ratings, mechanical dimensions, pitch spacing, orientation, mounting method, housing material, and safety certifications. The primary distinction is the termination style (press-fit versus solder) and minor dimensional variations in contact tail length and insulation height, which do not affect functional interchangeability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1803390 is the qualified substitute for the obsolete 1897924 based on the following engineering criteria:

Electrical Equivalence: Both parts maintain identical current (8A) and voltage (250V IEC / 300V UL) ratings, ensuring safe operation in existing circuit designs without derating or modification.

Mechanical Interchangeability: Matching pitch (0.150" / 3.81mm), position count (14), orientation (90° right-angle), and mounting method (through-hole) confirm direct mechanical compatibility with existing PCB layouts and mating connectors.

Material & Safety Compliance: Both components utilize PBT housing with UL94 V-0 flammability rating. The 1803390 carries ROHS3 compliance, representing current regulatory alignment compared to the obsolete 1897924's RoHS compliance status.

Active Product Status: The 1803390 is classified as active, ensuring long-term availability, supply chain continuity, and manufacturer support for future procurement cycles.

Termination Consideration: The 1803390 employs solder termination versus the 1897924's press-fit design. This difference requires PCB design verification to confirm solder pad compatibility and assembly process alignment.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1803390 directly replace the 1897924 without PCB modification?

A: Mechanical and electrical compatibility is confirmed. However, the termination style differs (solder versus press-fit). PCB pad design and assembly process must be verified to ensure compatibility. Contact tail length and insulation height show minor variations (0.138" vs. 0.134" and 0.276" vs. 0.285" respectively) that typically do not affect standard applications but should be confirmed for space-constrained designs.

Q: Are there any compliance or certification differences between these parts?

A: Both parts meet UL94 V-0 flammability requirements and carry RoHS compliance. The 1803390 specifically carries ROHS3 compliance, indicating alignment with current regulatory standards. Both are rated for identical electrical parameters (8A / 250V IEC, 8A / 300V UL).

Q: What is the primary reason for substitution?

A: The 1897924 is classified as obsolete. The 1803390 is an active product from the same manufacturer with matching electrical and mechanical specifications, providing supply continuity and long-term availability.

Q: Does the solder termination of the 1803390 affect performance compared to the press-fit design of the 1897924?

A: Termination style does not affect electrical performance or current/voltage ratings. Selection depends on PCB design and assembly capabilities. Solder termination requires compatible pad design and reflow or wave soldering processes.

Q: Are there inventory considerations for these parts?

A: The 1897924 shows 745 pieces in stock (obsolete status). The 1803390 shows 936 pieces in stock with active product status, indicating better long-term availability and supply chain reliability for new designs and ongoing procurement.
