Phoenix Contact 1897128 Terminal Block Header – Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1897128 is a 5-position terminal block header with male pins, shrouded design, and 4.6mm pitch in a 90° right-angle through-hole configuration. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations. The part operates at 8A (IEC) / 8A (UL) and 250V (IEC) / 300V (UL), with press-fit termination and PBT housing rated UL94 V-0.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1897128 is determined by the following critical parameters:

• Position count and pitch: Must maintain 5 positions at 0.138" (4.60mm) pitch
• Header type and orientation: Must be male pins, shrouded (4 side), 90° right-angle configuration
• Electrical ratings: Must support minimum 8A (IEC) and 250V (IEC); UL ratings of 8A and 300V
• Mounting and termination: Through-hole mounting with compatible termination method
• Housing material and flammability: PBT housing with UL94 V-0 rating
• Compliance: RoHS compliance required

The substitute part Phoenix Contact 1844249 meets these core substitution criteria while belonging to the active COMBICON MC series. Variations in termination style (solder vs. press-fit), current capacity (12A IEC vs. 8A IEC), and mechanical dimensions (contact tail length and insulation height) are within acceptable tolerance ranges for this product category.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1844249 is the designated substitute for the obsolete 1897128 based on the following engineering criteria:

Product Status: The 1844249 is an active product within the COMBICON MC series, ensuring continued availability and supply chain stability compared to the obsolete 1897128.

Electrical Compliance: Both parts meet IEC and UL voltage and current requirements. The 1844249 provides higher IEC current capacity (12A vs. 8A), which does not compromise compatibility for applications rated at 8A.

Regulatory Compliance: Both parts maintain UL94 V-0 flammability rating and PBT housing material. The 1844249 carries ROHS3 compliance, representing current regulatory alignment.

Mechanical Compatibility: Identical pitch (4.60mm), position count (5), orientation (90° right-angle), and shrouded male pin configuration ensure PCB footprint compatibility. Minor variations in contact tail length (0.138" vs. 0.134") and insulation height (0.276" vs. 0.285") fall within standard manufacturing tolerances for this connector class.

Termination Consideration: The primary difference is termination method—press-fit (1897128) versus solder (1844249). Selection depends on assembly process capability and design requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1844249 directly replace the 1897128 on existing PCBs?

A: Yes, for applications within the 8A electrical rating. The 4.60mm pitch, 5-position configuration, and 90° right-angle orientation are identical. PCB footprint compatibility is maintained. Termination method differs (solder vs. press-fit), requiring assembly process adjustment.

Q: What is the significance of the higher 12A IEC rating on the 1844249?

A: The 1844249 supports 12A at IEC standard, while the 1897128 is rated 8A. This does not affect substitution for 8A applications. The higher rating provides design margin and is not a limiting factor for compatibility.

Q: Are there mechanical dimension differences that affect mounting?

A: Contact tail length differs by 0.004" (0.10mm) and insulation height by 0.009" (0.25mm). These variations are within standard connector manufacturing tolerances and do not affect mounting or mating performance in standard applications.

Q: Why is the 1897128 obsolete?

A: The 1897128 belongs to the COMBICON EMC series, which has been superseded by the active COMBICON MC series. The 1844249 represents the current product line equivalent.

Q: Does RoHS3 compliance on the 1844249 affect compatibility?

A: No. ROHS3 compliance is a regulatory advancement and does not impact electrical or mechanical compatibility. It ensures the substitute meets current environmental standards.

Q: What assembly process is required for the 1844249?

A: The 1844249 uses solder termination, requiring standard PCB wave or reflow soldering processes. The 1897128 used press-fit termination. Verify assembly equipment capability before design transition.
