Phoenix Contact 1897694 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1897694 is a 2-position wire-to-board terminal block with side entry, 5.08mm pitch, and press-fit mounting. This component is classified as obsolete, making identification of suitable substitutes essential for ongoing design support and procurement planning. The part operates at 10A/300V with screw-rising cage clamp termination and M2 thread specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1897694 is determined by the following critical parameters:

Core Compatibility Criteria:

• Positions per level: 2
• Pitch: 0.200" (5.08mm)
• Mating orientation: Horizontal with board
• Wire gauge acceptance: 14-30 AWG
• Wire termination type: Screw - Rising Cage Clamp
• Voltage rating: minimum 300 V
• Current rating: minimum 10 A

The substitute part Phoenix Contact 1715721 meets these core criteria with the following considerations: it maintains identical pitch, position count, wire gauge range, and voltage specification. The current rating is elevated to 15A, providing margin above the original 10A requirement. The primary difference is the mounting method transition from press-fit to through-hole, which represents a mechanical interface change requiring PCB redesign.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1715721 is the identified substitute for the obsolete 1897694. Selection of this substitute is supported by the following factors:

Product Status: The 1715721 maintains active product status with current manufacturing support, addressing the obsolescence constraint of the original part.

Electrical Compatibility: Both parts maintain identical voltage (300V) and wire gauge (14-30 AWG) specifications. The 1715721 provides increased current capacity (15A versus 10A), which is compatible with applications designed for the original 10A rating.

Compliance: The 1715721 carries ROHS3 compliance certification, meeting current regulatory requirements. Both parts maintain MSL 1 (Unlimited) moisture sensitivity classification.

Mechanical Considerations: The transition from press-fit to through-hole mounting requires PCB redesign. The screw thread specification changes from M2 to M3, necessitating torque adjustment from 0.22-0.25 Nm to 0.5-0.6 Nm. The 1715721 includes interlocking side features not specified in the original part.

Frequently Asked Questions (FAQ)

Q: Can the 1715721 be used as a direct drop-in replacement for the 1897694?

A: No. While electrical parameters are compatible, the mounting method differs fundamentally. The 1897694 uses press-fit mounting; the 1715721 requires through-hole PCB design. PCB redesign is necessary.

Q: Are the pitch and position specifications identical between these parts?

A: Yes. Both parts maintain 0.200" (5.08mm) pitch and 2-position configuration, ensuring identical connector spacing and footprint width.

Q: What is the impact of the M2 to M3 screw thread change?

A: The screw thread upgrade from M2 to M3 increases clamping force capacity. Torque specification changes from 0.22-0.25 Nm to 0.5-0.6 Nm. Existing M2 fasteners are not compatible with the 1715721.

Q: Does the increased current rating of the 1715721 affect compatibility?

A: No. The 15A rating of the 1715721 exceeds the 10A requirement of the original application, providing operational margin. Applications designed for 10A operation remain within specification.

Q: What is the significance of the interlocking side feature on the 1715721?

A: The interlocking side feature on the 1715721 provides mechanical retention enhancement during assembly and operation. This feature is not present on the 1897694 but does not prevent substitution.

Q: Are both parts RoHS compliant?

A: Yes. The 1897694 is RoHS Compliant; the 1715721 is ROHS3 Compliant. Both meet current environmental compliance requirements.
