Weidmüller 995022 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Weidmüller 995022 is a 24-position wire-to-board terminal block with 5mm pitch, designed for horizontal mounting through PCB holes. This component features side-entry interlocking capability and screw-clamping wire termination, supporting 15A at 300V across wire gauges 12-26 AWG. The product is classified as obsolete, making identification of active equivalent components essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

The TE Connectivity AMP Connectors part number 2-1986711-4 qualifies as a functional substitute based on the following critical parameters:

• Position Count & Pitch: Both components provide 24 positions at 0.197" (5.00mm) pitch, ensuring mechanical and electrical compatibility in PCB layouts
• Mating Orientation: Both feature horizontal-with-board configuration for identical mounting geometry
• Voltage Rating: Both rated at 300V, meeting electrical system requirements
• Mounting Type: Both use through-hole PCB mounting
• Interlocking Feature: Both incorporate side-entry interlocking capability
• Contact Material: Both use copper alloy with tin plating for equivalent electrical performance

Differences in current rating (16A vs 15A), wire gauge range (12-30 AWG vs 12-26 AWG), termination method (screwless push-button vs screw-clamping), and operating temperature range represent design variations that do not preclude substitution when system requirements fall within the substitute's specifications.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 2-1986711-4 is an active product with ROHS3 compliance and MSL rating of 1 (Unlimited), providing superior long-term availability compared to the obsolete Weidmüller 995022. The substitute meets or exceeds all critical electrical parameters: voltage rating (300V), current capacity (16A vs 15A requirement), and wire gauge accommodation (12-30 AWG vs 12-26 AWG requirement).

The primary design difference is termination method: the substitute uses screwless push-button clamping versus screw-clamping on the original. This change requires PCB layout and assembly procedure evaluation to confirm compatibility with existing connector mating interfaces and installation tooling.

The substitute's extended operating temperature range (-40°C ~ 110°C) and improved compliance status support deployment in applications requiring broader environmental tolerance or regulatory documentation.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 2-1986711-4 directly replace the Weidmüller 995022 in existing designs?

A: Mechanical and electrical compatibility is confirmed for PCB mounting geometry and electrical performance. The screwless termination method requires verification that mating connectors and assembly procedures are compatible with push-button clamping versus screw-clamping operation.

Q: What are the critical parameters that define substitution eligibility?

A: Position count (24), pitch (5.00mm), mating orientation (horizontal with board), voltage rating (300V), and through-hole mounting type are the primary determinants. Both components meet these criteria.

Q: Does the wire gauge range difference affect substitution?

A: The substitute accommodates 12-30 AWG versus the original 12-26 AWG. This represents expanded capability and does not restrict substitution for applications using the original wire gauge range.

Q: What compliance advantages does the substitute offer?

A: The TE Connectivity part is ROHS3 compliant with MSL 1 (Unlimited), whereas the Weidmüller 995022 is obsolete. This ensures long-term availability and regulatory alignment for new production.

Q: How do the termination methods differ functionally?

A: The original uses M3 screw-clamping with specified torque (0.5-0.6 Nm). The substitute uses screwless push-button clamping, eliminating screw torque requirements but requiring different mating connector design and assembly methodology.
