Phoenix Contact 1755664 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1755664 is a 10-position terminal block plug designed for unshrouded headers with 5.00mm pitch spacing and 90° wire entry orientation. This component is classified as a screw-terminal connector with rising cage clamp termination, suitable for free-hanging inline mounting applications. The part maintains Active product status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance can be maintained across different manufacturer designs while accommodating application-specific requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1755664 is determined by the following critical parameters:

Electrical Compatibility: Current and voltage ratings must meet or exceed IEC specifications (10A minimum, 630V minimum). UL ratings provide secondary validation for North American applications.

Mechanical Compatibility: 10-position configuration with pitch spacing between 5.00mm and 5.08mm is acceptable within standard connector tolerance ranges. Wire entry orientation (90° vs. 180°) represents a functional difference but does not preclude substitution when application geometry permits. Termination method (screw-based systems) must maintain compatibility with the unshrouded header interface.

Regulatory Compliance: RoHS3 compliance and REACH unaffected status are mandatory. Material flammability rating UL94 V-0 is required.

Wire Gauge Compatibility: Acceptable wire gauge range 14-28 AWG (0.2-2.5mm²) establishes the termination capacity baseline.

The Weidmüller 1282560000 qualifies as a substitute based on these parameters, with documented differences in wire entry angle, pitch tolerance, and current rating noted in the comparison table below.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1755664 Selection Criteria:

• Applications requiring 630V IEC voltage rating
• 90° wire entry orientation is functionally required
• Rising cage clamp termination preferred for specific interface design
• RoHS3 compliance explicitly mandated

Weidmüller 1282560000 Selection Criteria:

• Applications operating at 400V IEC maximum or lower
• 180° wire entry orientation compatible with application geometry
• Higher IEC current rating (17.5A) acceptable for margin requirements
• RoHS compliance sufficient (standard RoHS, not RoHS3)
• UL ratings (10A, 300V) match primary specification

Both parts maintain Active product status and UL94 V-0 flammability compliance. Selection between these components depends on voltage requirement validation and wire entry orientation feasibility within the target application enclosure.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1282560000 replace the Phoenix Contact 1755664 in all applications?

A: Substitution is conditional. The Weidmüller part operates at 400V IEC maximum, which is below the Phoenix Contact specification of 630V IEC. Applications requiring 630V operation cannot use the Weidmüller substitute. Additionally, the 180° wire entry differs from the 90° orientation of the Phoenix Contact; physical space constraints may prevent installation.

Q: What is the pitch tolerance between 5.00mm and 5.08mm?

A: The 0.08mm difference represents a 1.6% variance within standard connector manufacturing tolerances. Both parts interface with 10-position unshrouded headers; however, mechanical fit should be validated in the target application before production deployment.

Q: Are both parts suitable for UL-regulated applications?

A: Yes. Both parts carry UL ratings of 10A at 300V and UL94 V-0 flammability classification. The Phoenix Contact part also carries IEC ratings (10A, 630V), while the Weidmüller part carries IEC ratings (17.5A, 400V). Application standards determine which certification pathway applies.

Q: What is the difference between rising cage clamp and clamping yoke termination?

A: Both are screw-based termination methods. Rising cage clamp (Phoenix Contact) uses a spring-loaded cage that rises as the screw tightens. Clamping yoke with tension sleeve (Weidmüller) uses a different mechanical design for wire retention. Both methods are suitable for 0.2-2.5mm² wire gauge range; selection depends on interface compatibility with the unshrouded header connector.

Q: Is RoHS3 compliance required, or is standard RoHS sufficient?

A: This depends on application and regional requirements. RoHS3 is the current EU directive standard and is mandatory for new designs in EU markets. RoHS (standard) is acceptable for legacy applications or non-EU markets. The Phoenix Contact part meets RoHS3; the Weidmüller part meets standard RoHS.

Q: Can wire gauge 12 AWG be used with the Phoenix Contact 1755664?

A: No. The Phoenix Contact 1755664 accepts 14-28 AWG maximum. The Weidmüller 1282560000 accepts 12-26 AWG, which includes 12 AWG. If 12 AWG termination is required, the Weidmüller part is necessary.
