Weidmüller 995161 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Weidmüller 995161 is a 12-position wire-to-board terminal block with 0.200" (5.08mm) pitch, designed for horizontal mounting through PCB holes. This component belongs to the Omnimate LP series and is classified as obsolete. Due to its obsolete status, identifying equivalent substitute parts from the active product line is essential for ongoing design support, maintenance, and new production requirements.

Key Parameters

Substitute Part Grouping Explanation

The Weidmüller 9994000000 qualifies as a direct substitute for the 995161 based on the following critical parameters:

• Electrical Compatibility: Both parts maintain identical current (15 A) and voltage (300 V) ratings, ensuring equivalent electrical performance in the same circuit applications.
• Mechanical Compatibility: Both feature 12 positions at 0.200" (5.08mm) pitch with horizontal board mounting and through-hole installation, enabling direct PCB layout compatibility.
• Termination Method: Both use screw-clamping with tension sleeve wire termination and side interlocking features, maintaining identical connector interface characteristics.
• Material & Plating: Both employ copper alloy contacts with tin plating and polyamide-based housing materials, ensuring equivalent corrosion resistance and environmental performance.
• Regulatory Compliance: Both are RoHS compliant and REACH unaffected, meeting current environmental and safety standards.

The primary differences—wire gauge range, operating temperature range, screw specifications, and product status—do not prevent substitution when the application requirements fall within the substitute part's specifications.

Engineering Selection Recommendations

The Weidmüller 9994000000 is the recommended substitute for the obsolete 995161 based on the following factors:

• Active Product Status: The 9994000000 is an active product in the Omnimate LM series, ensuring long-term availability, technical support, and supply chain continuity.
• Regulatory Compliance: Both parts maintain RoHS compliance and REACH unaffected status, meeting current environmental regulations without additional qualification.
• Electrical & Mechanical Equivalence: Identical current, voltage, pitch, position count, and mounting configuration enable direct substitution in existing designs without PCB layout modifications.
• Enhanced Operating Range: The substitute part supports an extended operating temperature range (-50°C ~ 120°C versus -20°C ~ 100°C), providing greater thermal margin for demanding applications.
• Wire Gauge Consideration: The substitute accepts 14-24 AWG wire, which overlaps with the main part's 12-26 AWG range. Applications using 12 or 26 AWG wire require evaluation against the substitute's narrower specification.

Frequently Asked Questions (FAQ)

Q: Can the 9994000000 be used as a direct replacement for the 995161 in existing assemblies?

A: Yes, for applications where wire gauge falls within 14-24 AWG and operating temperature remains within -50°C ~ 120°C. The identical pitch, position count, electrical ratings, and mounting configuration enable direct substitution without PCB redesign.

Q: What is the impact of the different screw specifications (M3 vs. M2.5)?

A: The substitute uses M2.5 screws with lower torque specifications (0.4-0.5 Nm versus 0.5-0.6 Nm). Termination procedures must follow the substitute part's torque requirements to ensure proper clamping force and electrical contact.

Q: Are there wire gauge limitations when substituting?

A: Yes. The main part supports 12-26 AWG, while the substitute supports 14-24 AWG. Applications using 12 AWG or 26 AWG wire cannot use the 9994000000 substitute. Verify wire gauge requirements before selection.

Q: What are the packaging differences?

A: The 995161 is supplied in standard packaging, while the 9994000000 is supplied in bulk packaging. Confirm packaging requirements for your procurement and assembly processes.

Q: Why is the operating temperature range different?

A: The substitute part uses Wemid thermoplastic housing material, which provides superior thermal stability compared to the main part's PA66 nylon material, enabling the extended -50°C ~ 120°C operating range.

Q: Are both parts RoHS and REACH compliant?

A: Yes, both the 995161 and 9994000000 are RoHS compliant and REACH unaffected, meeting current environmental and regulatory requirements.
