Weidmüller 1628050000 Terminal Block Plug Equivalent & Substitute Parts

Part Overview

The Weidmüller 1628050000 is a 4-position terminal block plug with female sockets, 7.5mm pitch, designed for 180° free-hanging in-line applications. This component features screw-clamping termination and is rated for 15A at 500V (IEC) or 300V (UL). The part is classified as obsolete, making equivalent substitutes necessary for ongoing system maintenance and new designs requiring compatible connectivity solutions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 1628050000 is determined by the following critical parameters:

• Mechanical Compatibility: 4 positions, 7.5mm pitch, 180° wire entry, free-hanging mounting
• Electrical Compatibility: Current and voltage ratings must meet or exceed IEC 15A / 500V or UL 15A / 300V requirements
• Termination Interface: Screw-based termination (clamping yoke or rising cage clamp acceptable)
• Wire Gauge Acceptance: Must accommodate 12-26 AWG minimum range
• Housing Material: UL94 V-0 flammability rating required
• Contact Finish: Tin plating standard

The identified substitutes (Phoenix Contact 1766903 and TE Connectivity 282959-4) meet these core mechanical and electrical parameters, though with variations in specific ratings and wire gauge ranges as detailed in the comparison table.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1766903: This substitute is active in production and meets UL electrical requirements (15A / 300V). It provides higher IEC voltage rating (1 kV vs. 500V) and expanded wire gauge compatibility (12-30 AWG). The rising cage clamp termination is functionally equivalent to the clamping yoke design. RoHS3 compliance is confirmed. Screw size differs (M3 vs. M2.5), requiring verification of mounting interface compatibility in the target application.

TE Connectivity 282959-4: This substitute is active in production and meets UL electrical requirements (15A / 300V). It offers the widest wire gauge range (12-30 AWG, 0.05-2mm²) and extended operating temperature range (-40°C to 110°C vs. -20°C to 100°C). RoHS3 compliance is confirmed. Like the Phoenix Contact option, screw size is M3, and REACH status indicates affected substances requiring compliance verification. Rising cage clamp termination provides functional equivalence.

Both substitutes maintain mechanical interchangeability through identical pitch, position count, and wire entry orientation. Selection should prioritize application-specific requirements for wire gauge range, operating temperature, and mounting interface compatibility.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1766903 or TE Connectivity 282959-4 directly replace the Weidmüller 1628050000 in existing installations?

A: Mechanical and electrical compatibility is confirmed for both substitutes. However, the screw size change from M2.5 to M3 requires verification that the mating connector or mounting structure accommodates the larger fastener. Wire gauge ranges differ; confirm that your application's wire sizes fall within the substitute's acceptable range.

Q: What is the primary difference in termination style between the original and substitutes?

A: The Weidmüller 1628050000 uses a clamping yoke (tension sleeve) termination, while both substitutes employ a rising cage clamp. Both are screw-based mechanisms and provide equivalent electrical and mechanical performance for wire retention and contact pressure.

Q: Are there temperature limitations when substituting with TE Connectivity 282959-4?

A: The TE Connectivity part extends the operating range to -40°C to 110°C, compared to the original -20°C to 100°C. This provides greater flexibility for applications requiring lower or higher temperature operation. The Phoenix Contact substitute does not specify an operating temperature range.

Q: Do the substitutes support the same wire gauge as the original part?

A: The original Weidmüller part accepts 12-26 AWG. Both substitutes accept 12-30 AWG, providing broader compatibility. However, the TE Connectivity part specifies a minimum of 0.05mm², which is narrower than the Phoenix Contact minimum of 0.2mm². Verify your specific wire gauge requirements against each substitute's range.

Q: What compliance certifications should I verify before selecting a substitute?

A: Both substitutes are RoHS3 compliant and REACH-unaffected (Phoenix Contact) or REACH-affected (TE Connectivity). Confirm that your application's regulatory requirements align with these certifications. The TE Connectivity part requires additional REACH substance compliance verification due to its affected status.

Q: Is color compatibility a concern when substituting?

A: The original part is black, while both substitutes are green. Color differences do not affect electrical or mechanical function but may impact visual identification or system documentation. Verify that color coding is not a critical requirement in your application.
