Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 1623520000 is determined by the following critical parameters:

• Connector Type & Configuration: 5-position plug with female sockets
• Pitch Specification: 0.300" (7.62mm) center-to-center spacing
• Mounting Orientation: 180° free-hanging in-line configuration
• Electrical Ratings: Minimum 15 A current capacity and 300 V voltage rating (UL)
• Wire Compatibility: Support for 12-26 AWG conductor sizes
• Termination Method: Screw-based clamping mechanism
• Housing Material & Flammability: UL94 V-0 rated polymer construction
• Contact Finish: Tin plating for corrosion resistance

The TE Connectivity AMP Connectors part 796981-5 meets these core substitution criteria while maintaining functional and electrical compatibility within the specified parameter ranges.

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 796981-5 is a direct functional substitute for the obsolete Weidmüller 1623520000. Selection rationale is based on the following factors:

Product Status: The TE Connectivity part maintains active product status, ensuring continued availability and supply chain reliability compared to the obsolete Weidmüller component.

Electrical Compliance: Both parts meet identical UL electrical ratings (15 A, 300 V) and share UL94 V-0 flammability certification, confirming equivalent safety performance in industrial applications.

Mechanical Compatibility: Identical pitch (7.62mm), connector type (5-position female socket plug), and mounting configuration (180° free-hanging in-line) ensure direct mechanical interchangeability in existing installations.

Wire Gauge Compatibility: The TE part supports an extended wire gauge range (12-30 AWG / 0.05-3mm²) that encompasses the original specification (12-26 AWG / 2.5mm²), providing design flexibility for future applications.

Environmental Performance: The TE part's extended operating temperature range (-40°C ~ 110°C) exceeds the original specification (-20°C ~ 100°C), offering improved performance in demanding thermal environments.

Regulatory Compliance: The TE part is RoHS Compliant and REACH Affected, meeting current environmental and hazardous substance regulations applicable to electronic components.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 796981-5 directly replace the Weidmüller 1623520000 in existing installations?

A: Yes. Both parts share identical pitch (7.62mm), connector configuration (5-position female socket plug), mounting type (180° free-hanging in-line), and electrical ratings (15 A / 300 V UL). Direct mechanical and electrical interchangeability is confirmed.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Termination mechanism—Weidmüller uses screw-clamping yoke; TE uses rising cage clamp; (2) Wire gauge range—TE supports 12-30 AWG versus Weidmüller's 12-26 AWG; (3) Operating temperature—TE range is -40°C ~ 110°C versus Weidmüller's -20°C ~ 100°C; (4) Contact material—Weidmüller uses copper alloy; TE uses phosphor bronze; (5) Housing material—Weidmüller uses PBT; TE uses PA66 nylon; (6) Product status—TE is active; Weidmüller is obsolete.

Q: Are there any compatibility concerns with the different termination styles?

A: No. Both termination methods (screw-clamping yoke and rising cage clamp) are industry-standard screw-based mechanisms designed for the same wire gauge ranges and current ratings. Functional performance is equivalent.

Q: Does the TE part support the same wire gauges as the original?

A: Yes, and more. The TE part supports 12-30 AWG (0.05-3mm²), which fully encompasses the original specification of 12-26 AWG (2.5mm²). This extended range provides additional design flexibility without compromising compatibility.

Q: What is the difference in screw size and torque specifications?

A: Weidmüller specifies M2.5 screws with 0.4-0.5 Nm torque; TE specifies M3 screws with 0.79 Nm torque. These differences reflect the different termination mechanisms but do not affect interchangeability. Follow the torque specification for the part being installed.

Q: Is the TE part suitable for applications requiring extended temperature operation?

A: Yes. The TE part's operating temperature range (-40°C ~ 110°C) exceeds the original specification, making it suitable for applications requiring operation at lower or higher temperatures than the original Weidmüller part.

Q: What packaging is available for the TE Connectivity substitute?

A: The TE Connectivity 796981-5 is available in bulk packaging, with 1008 pieces currently in stock as new original inventory.
