Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 995021 is determined by the following critical parameters:

• Position Count & Pitch: 23 positions at 0.197" (5.00mm) spacing (mechanical compatibility requirement)
• Mating Orientation: Horizontal with Board (PCB layout constraint)
• Mounting Type: Through Hole (assembly process compatibility)
• Electrical Ratings: Minimum 15 A current and 300 V voltage (functional requirement)
• Wire Gauge Compatibility: Acceptance of 12-26 AWG minimum range
• Wire Termination Method: Screw-based clamping (tooling and assembly compatibility)
• Contact Material: Copper alloy with tin plating (electrical and corrosion performance)

The TE Connectivity AMP Connectors part number 2-1986711-3 meets these substitution criteria with the following considerations: it maintains identical position count, pitch, orientation, and mounting type; exceeds electrical ratings (16 A current, 300 V voltage); accommodates an extended wire gauge range (12-30 AWG); and uses compatible contact materials. The primary difference is the wire termination method (screwless push-button clamp versus screw-clamping yoke), which represents a functional alternative rather than a direct mechanical replacement.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 2-1986711-3 is the identified equivalent for the obsolete Weidmüller 995021. Selection should be based on the following factors:

Product Status: The Weidmüller 995021 is obsolete, whereas the TE Connectivity alternative is active and currently manufactured, ensuring long-term availability and supply chain continuity.

Compliance & Certifications: The TE Connectivity part carries ROHS3 compliance, meeting current regulatory requirements for new designs and manufacturing. The Weidmüller part is not subject to RoHS classification due to its obsolete status.

Electrical Performance: The TE Connectivity substitute exceeds the original specifications with 16 A current capacity versus 15 A, and maintains the 300 V voltage rating. Both components use identical contact materials (copper alloy with tin plating).

Operating Temperature Range: The TE Connectivity part provides an extended operating range (-40°C ~ 110°C) compared to the original (-20°C ~ 100°C), offering greater thermal flexibility for diverse applications.

Wire Termination Methodology: The primary functional difference is the termination approach. The original uses screw-clamping with a tension sleeve; the substitute uses a screwless push-button clamp system. Both methods provide secure wire retention and are suitable for industrial terminal block applications. Assembly procedures and tooling requirements will differ accordingly.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 2-1986711-3 be used as a direct mechanical replacement for the Weidmüller 995021?

A: Yes, for PCB layout and mounting purposes. Both components share identical position count (23), pitch (5.00mm), mating orientation (horizontal with board), and through-hole mounting type. The physical footprint is compatible. However, the wire termination method differs: the original uses screw-clamping, while the substitute uses a screwless push-button clamp. Assembly procedures and operator training may require adjustment.

Q: Are the electrical ratings compatible?

A: Yes. The TE Connectivity part meets or exceeds all electrical requirements: 16 A current (versus 15 A original), 300 V voltage (identical), and compatible contact materials (copper alloy with tin plating). The extended wire gauge acceptance (12-30 AWG versus 12-26 AWG) provides additional flexibility.

Q: What is the impact of the different wire termination methods?

A: The Weidmüller 995021 uses screw-clamping with a tension sleeve, requiring a screwdriver and torque specification (0.5-0.6 Nm). The TE Connectivity 2-1986711-3 uses a screwless push-button clamp, eliminating the need for torque tools and potentially reducing assembly time. Both methods provide secure retention and are suitable for industrial applications. Operator training and assembly procedures will differ.

Q: Is the TE Connectivity part suitable for new designs?

A: Yes. The TE Connectivity 2-1986711-3 is active and ROHS3 compliant, meeting current regulatory and manufacturing standards for new product development. It provides superior compliance status compared to the obsolete Weidmüller part.

Q: What are the temperature operating range differences?

A: The Weidmüller 995021 operates from -20°C to 100°C. The TE Connectivity 2-1986711-3 operates from -40°C to 110°C, providing a wider thermal envelope suitable for applications requiring extended temperature performance.

Q: Are there any packaging differences?

A: The Weidmüller part is listed with no specified packaging designation. The TE Connectivity substitute is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.
