Phoenix Contact 1897270 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1897270 is a 5-position terminal block header with male pins, shrouded on 4 sides, featuring 90° right-angle through-hole mounting and 4.6mm pitch. 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/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 1897270 is determined by the following critical parameters:

• Electrical Ratings: Current (8A IEC/UL) and voltage (250V IEC / 300V UL) must be maintained or exceeded
• Physical Configuration: 5-position count, 4.6mm pitch, 90° right-angle orientation, and through-hole mounting are mandatory
• Connector Type: Male pins with 4-side shrouding required
• Housing Material: PBT with UL94 V-0 flammability rating
• Compliance: RoHS compliance and MSL 1 rating

The Phoenix Contact 1843826 qualifies as a substitute based on matching electrical ratings, position count, pitch, orientation, mounting type, housing material, and flammability rating. Differences in termination style (press-fit vs. solder), series designation (COMBICON EMC vs. COMBICON MC), product status (obsolete vs. active), and minor dimensional variations in contact tail length and insulation height do not prevent functional substitution when electrical and mechanical compatibility requirements are met.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1843826 is the qualified substitute for the obsolete 1897270 terminal block header. Both components maintain identical electrical ratings (8A at 250V IEC / 300V UL), mechanical configuration (5-position, 4.6mm pitch, 90° right-angle), and material specifications (PBT housing, UL94 V-0 rating).

The primary distinction is termination methodology: the 1897270 uses press-fit termination while the 1843826 employs solder termination. This difference requires corresponding changes to PCB design and assembly processes but does not affect electrical performance or mechanical compatibility.

The 1843826 carries active product status with ROHS3 compliance, providing superior long-term availability and regulatory alignment compared to the obsolete 1897270. 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 through-hole mounting applications and do not compromise functional substitution.

Frequently Asked Questions (FAQ)

Q: Can the 1843826 directly replace the 1897270 in existing designs?

A: Electrical and mechanical compatibility is confirmed. However, the termination method differs (solder vs. press-fit), requiring PCB layout and assembly process modifications. Verify that your manufacturing capability supports solder termination before implementation.

Q: Are the dimensional differences between these parts significant?

A: Contact tail length differs by 0.004" (0.10mm) and insulation height by 0.009" (0.25mm). These variations are within standard manufacturing tolerances for through-hole terminal blocks and do not prevent functional substitution in standard PCB applications.

Q: What is the impact of the different RoHS compliance levels?

A: The 1897270 meets RoHS Compliant standards, while the 1843826 meets ROHS3 Compliant standards. ROHS3 represents an updated compliance framework with no functional impact on component performance. The 1843826 provides enhanced regulatory alignment for new designs.

Q: Does the active product status of the 1843826 affect compatibility?

A: No. Active product status indicates ongoing manufacturing and availability, which is advantageous for procurement. Compatibility is determined by electrical ratings, mechanical configuration, and material specifications, all of which match between the two parts.

Q: Are there packaging differences between these parts?

A: The 1897270 packaging specification is not provided. The 1843826 is supplied in bulk packaging. Confirm packaging requirements for your application and procurement process.
