Phoenix Contact 1897322 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1897322 is a 10-position terminal block header with male pins, shrouded on four sides, featuring 0.138" (4.60mm) 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. The part operates at 8A (IEC/UL) and 250V (IEC) / 300V (UL), with UL94 V-0 flammability rating and RoHS compliance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1897322 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 10
• Pitch: 0.138" (4.60mm)
• Header Orientation: 90°, Right Angle
• Type: Header, Male Pins, Shrouded (4 Side)
• Mounting Type: Through Hole
• Current Rating (IEC): 8A minimum
• Voltage Rating (IEC): 250V minimum
• Housing Material: Polybutylene Terephthalate (PBT)
• Material Flammability Rating: UL94 V-0
• Contact Mating Finish: Tin

The Phoenix Contact 1843871 qualifies as a direct substitute based on these parameters. While the termination style differs (Solder vs. Press-Fit) and minor dimensional variations exist in contact tail length and insulation height, the electrical performance, mechanical interface, and regulatory compliance remain equivalent for system-level functionality.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1843871 is the qualified substitute for the obsolete 1897322 based on electrical and mechanical equivalence. The 1843871 offers the advantage of active product status, ensuring continued availability and supply chain stability. Both parts maintain identical electrical ratings (8A/250V IEC, 8A/300V UL) and comply with UL94 V-0 flammability requirements.

The primary distinction is termination methodology: the 1897322 uses press-fit termination, while the 1843871 employs solder termination. This difference requires PCB design consideration but does not affect electrical performance or mechanical interface compatibility. The 1843871 carries ROHS3 compliance, representing current regulatory alignment compared to the RoHS Compliant designation of the 1897322.

Minor dimensional variations in contact tail length (0.138" vs. 0.134") and insulation height (0.276" vs. 0.285") fall within acceptable tolerances for standard through-hole PCB applications and do not compromise functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can the 1843871 directly replace the 1897322 on existing PCBs?

A: Mechanical and electrical compatibility is confirmed. However, the termination style difference (solder vs. press-fit) requires PCB design verification. Press-fit designs require specific pad geometry and hole tolerances; solder termination uses standard through-hole pad specifications. Consult PCB layout documentation to confirm compatibility.

Q: What is the significance of the product status change from Obsolete to Active?

A: The 1843871 is in active production, ensuring long-term availability and supply continuity. The 1897322, being obsolete, has limited remaining inventory and no future manufacturing. For new designs or long-term production, the 1843871 is the appropriate selection.

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

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

Q: Do both parts meet current regulatory requirements?

A: Both parts comply with RoHS directives. The 1843871 carries ROHS3 compliance, representing the current regulatory standard. Both maintain UL94 V-0 flammability ratings and identical electrical certifications (IEC and UL).

Q: What packaging differences exist between these parts?

A: The 1897322 is listed with unspecified packaging, while the 1843871 is supplied in Bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Are there any compliance or certification differences?

A: Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications. The 1843871 includes REACH Unaffected status. Electrical ratings, flammability classifications, and moisture sensitivity levels are equivalent.
