Phoenix Contact 1897720 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1897720 is a 5-position wire-to-board terminal block with 0.200" (5.08mm) pitch, designed for horizontal board mounting using press-fit technology. This component belongs to the COMBICON EMKDS series and is classified as obsolete. Due to its obsolete status and limited long-term availability, identifying functionally equivalent substitute parts is essential for design continuity and procurement planning. The primary substitute maintains core electrical and mechanical compatibility while offering enhanced current capacity and active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1897720 is determined by the following critical parameters:

• Position count and pitch: Both main and substitute parts maintain 5 positions at 0.200" (5.08mm) spacing, ensuring PCB footprint compatibility
• Electrical ratings: Voltage rating of 300 V is maintained; current capacity is equal or greater
• Wire termination method: Screw-based rising cage clamp termination is preserved across all substitutes
• Housing material: Polyamide (PA) nylon construction remains consistent
• Compliance standards: RoHS compliance is maintained or exceeded

The primary substitute (1715750) differs in mounting technology (through-hole versus press-fit) and current capacity (15 A versus 10 A), but these differences represent functional improvements rather than incompatibilities.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1715750 is the qualified substitute for the 1897720. Selection rationale is based on the following factors:

• Product status: The 1715750 maintains active product status, ensuring continued availability and manufacturer support, whereas the 1897720 is obsolete
• Compliance: The 1715750 meets ROHS3 compliance, representing current regulatory standards; the 1897720 meets RoHS Compliant status
• Electrical performance: The 1715750 provides equal voltage rating (300 V) and superior current capacity (15 A versus 10 A), offering design margin improvement
• Mechanical compatibility: Identical pitch, position count, and wire termination method ensure direct functional replacement
• PCB integration: Mounting type differs (through-hole versus press-fit); PCB design modification is required to accommodate the alternative mounting technology

Frequently Asked Questions (FAQ)

Q: Can the 1715750 be used as a direct drop-in replacement for the 1897720?

A: Electrical and mechanical compatibility is confirmed for wire gauge, pitch, position count, and termination method. However, mounting technology differs: the 1897720 uses press-fit mounting while the 1715750 requires through-hole mounting. PCB design modification is necessary.

Q: What is the primary reason to substitute the 1897720?

A: The 1897720 is classified as obsolete. The 1715750 is an active product with equivalent electrical specifications and improved current capacity, ensuring long-term procurement viability.

Q: Are there compliance differences between these parts?

A: Both parts are RoHS compliant. The 1715750 meets ROHS3 compliance, which represents the current regulatory standard. Both parts are rated for 300 V and support 14-30 AWG wire gauge.

Q: Does the current rating difference affect compatibility?

A: The 1715750 provides 15 A capacity compared to the 1897720's 10 A rating. This represents a performance improvement and does not create compatibility issues; circuits designed for 10 A operation remain within the 1715750's specifications.

Q: What packaging considerations apply to these parts?

A: The 1897720 is available in standard packaging; the 1715750 is supplied in bulk packaging. Verify packaging requirements for your procurement process.
