Weidmüller 995166 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Weidmüller 995166 is a 17-position wire-to-board terminal block with 0.200" (5.08mm) pitch, designed for horizontal mounting with through-hole PCB installation. This component belongs to the Omnimate LP series and features screw-clamping wire termination with side interlocking capability. The part is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations where similar electrical and mechanical specifications are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 995166 is determined by the following critical parameters:

• Position Count & Pitch: Both main and substitute parts must maintain 17 positions at 0.200" (5.08mm) pitch to ensure PCB footprint compatibility
• Mating Orientation: Horizontal with board orientation is required for mechanical fit
• Mounting Type: Through-hole mounting must be preserved for PCB assembly compatibility
• Interlocking Feature: Side interlocking capability must be present for mechanical stability
• Electrical Ratings: Current and voltage ratings of substitute parts must meet or exceed the original specification (15 A, 300 V minimum)
• Wire Gauge Compatibility: Substitute parts must accommodate the wire gauge range of the application
• Contact Material & Plating: Copper alloy with tin plating ensures consistent electrical performance and corrosion resistance

The Weidmüller 1330880000 qualifies as a substitute based on these parameters, despite differences in wire termination method, housing material, and enhanced electrical ratings.

Engineering Selection Recommendations

Primary Substitute: Weidmüller 1330880000

The Weidmüller 1330880000 is the qualified substitute for the obsolete 995166 model. Selection is based on the following engineering criteria:

• Functional Equivalence: Both parts maintain identical position count (17), pitch (5.08mm), mating orientation, and mounting type, ensuring direct PCB footprint compatibility
• Electrical Performance: The substitute meets the 300 V voltage requirement and exceeds the 15 A current rating with a 20 A capability, providing margin for application demands
• Product Status & Availability: The 1330880000 is in active production status with confirmed inventory (712 pcs), ensuring long-term supply chain reliability compared to the obsolete 995166
• Compliance & Certifications: The substitute is RoHS Compliant and REACH Unaffected, meeting modern regulatory requirements
• Mechanical Compatibility: Side interlocking feature and through-hole mounting are preserved, maintaining mechanical stability and assembly compatibility

Critical Considerations for Implementation:

The primary difference between these parts is the wire termination method. The 995166 uses screw-clamping termination, while the 1330880000 employs screwless push-in spring termination. This requires assembly procedure modification but does not affect electrical or mechanical compatibility. Additionally, verify that application wire gauges fall within the 12-24 AWG range supported by the substitute, as the original part accommodates up to 26 AWG.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1330880000 be used as a direct replacement for the 995166 without PCB redesign?

A: Yes. Both parts share identical position count (17), pitch (5.08mm), mating orientation (horizontal with board), and through-hole mounting type. PCB footprint compatibility is preserved. However, assembly procedures differ due to the change from screw-clamping to push-in spring termination.

Q: What is the primary difference between these two terminal blocks?

A: The wire termination method differs. The 995166 uses screw-clamping with a tension sleeve, requiring a screwdriver for wire insertion. The 1330880000 uses a screwless push-in spring mechanism, allowing direct wire insertion without tools. Both methods provide equivalent electrical connection reliability.

Q: Are there wire gauge compatibility issues when substituting?

A: The 995166 accommodates 12-26 AWG wire, while the 1330880000 supports 12-24 AWG. If your application uses 25-26 AWG wire, the substitute cannot be used without wire gauge modification. Verify your application's wire gauge specification before substitution.

Q: Does the substitute meet modern regulatory requirements?

A: Yes. The 1330880000 is RoHS Compliant and REACH Unaffected, meeting current regulatory standards. The original 995166 has "Not applicable" RoHS status due to its obsolete classification.

Q: What is the operating temperature range difference?

A: The 995166 operates from -20°C to 100°C, while the 1330880000 operates from -50°C to 120°C. The substitute provides an extended temperature range, suitable for applications requiring broader thermal performance.

Q: Is the current rating difference significant?

A: The 995166 is rated for 15 A, while the 1330880000 is rated for 20 A. The substitute exceeds the original specification, providing additional current capacity margin. This is advantageous for applications approaching the original 15 A limit.

Q: How does the housing material change affect performance?

A: The 995166 uses Polyamide (PA66) Nylon 6/6, while the 1330880000 uses Thermoplastic Wemid. Both materials provide adequate electrical insulation and mechanical strength for terminal block applications. Material selection should be verified against specific environmental conditions (chemical exposure, UV exposure, mechanical stress) in your application.

Q: Is inventory availability a concern?

A: The 995166 is obsolete with limited remaining stock (1072 pcs). The 1330880000 is in active production with confirmed inventory (712 pcs), ensuring reliable long-term supply chain access for future requirements.
