Phoenix Contact 1897306 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1897306 is an 8-position terminal block header with male pins, shrouded on 4 sides, designed for 90° right-angle through-hole mounting. This component operates at 8A (IEC/UL) and 250V (IEC) / 300V (UL) with 0.138" (4.60mm) pitch spacing. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1897306 is determined by the following critical parameters:

• Electrical Compatibility: Current rating (8A minimum), voltage rating (250V IEC / 300V UL minimum)
• Physical Compatibility: 8 positions, 0.138" (4.60mm) pitch, 90° right-angle orientation, through-hole mounting
• Mechanical Compatibility: Male pins with 4-side shrouding, PBT housing material, UL94 V-0 flammability rating
• Environmental Compliance: RoHS compliance status

The Phoenix Contact 1843855 qualifies as a direct functional 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) and minor dimensional variations in contact tail length and insulation height do not preclude substitution in applications where the solder termination method is acceptable.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1843855 is the primary substitute for the obsolete 1897306. Both components maintain identical electrical specifications (8A / 250V IEC, 8A / 300V UL) and mechanical form factors (8 positions, 4.60mm pitch, 90° right-angle, through-hole mounting). The 1843855 is currently in active production status, ensuring long-term availability and supply chain continuity.

The primary distinction between these parts is termination methodology: the 1897306 uses press-fit termination, while the 1843855 employs solder termination. This difference requires PCB design modification to accommodate solder-based connection rather than press-fit insertion. Minor dimensional variations in contact tail length (0.138" vs. 0.134") and insulation height (0.276" vs. 0.285") are within acceptable tolerances for standard through-hole PCB applications.

Both components meet equivalent environmental and compliance standards: UL94 V-0 flammability rating, RoHS compliance (with the 1843855 meeting ROHS3 specifications), and tin contact mating finish. The 1843855 is suitable for new designs and legacy system replacements where solder termination is compatible with existing manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can the 1843855 directly replace the 1897306 without PCB modifications?

A: No. The 1897306 uses press-fit termination while the 1843855 requires solder termination. PCB pad design and assembly process must be adapted accordingly. The through-hole mounting footprint remains compatible, but connection methodology differs fundamentally.

Q: Are the electrical ratings identical between these parts?

A: Yes. Both components are rated for 8A current and 250V (IEC) / 300V (UL) voltage. They are electrically interchangeable in terms of load capacity and voltage withstand.

Q: What is the significance of the contact tail length difference (0.138" vs. 0.134")?

A: The 0.004" (0.10mm) difference in contact tail length is negligible for standard through-hole PCB applications. Both lengths accommodate typical PCB thickness and solder joint formation without functional impact.

Q: Does the insulation height difference affect mechanical fit?

A: The 0.009" (0.25mm) increase in insulation height on the 1843855 does not compromise mechanical compatibility. This variation is within standard manufacturing tolerances and does not affect board-level integration or connector mating.

Q: Why is the 1897306 classified as obsolete?

A: The 1897306 has been superseded by the 1843855 in Phoenix Contact's product portfolio. The active production status of the 1843855 ensures continued availability and support for applications requiring 8-position, 4.60mm pitch terminal block headers.

Q: Are both parts RoHS compliant?

A: Yes. The 1897306 is RoHS Compliant, and the 1843855 meets the more stringent ROHS3 Compliant specification. Both satisfy environmental regulatory requirements for lead-free manufacturing and hazardous substance restrictions.

Q: What packaging options are available?

A: The 1897306 was supplied in standard packaging (not specified in available data). The 1843855 is available in bulk packaging, suitable for production volume requirements.
