Weidmüller 995171 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Weidmüller 995171 is a 22-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 features screw-clamping wire termination with side interlocking. The part is currently obsolete, making identification of compatible substitutes essential for ongoing system maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the Weidmüller 995171 is determined by the following critical parameters:

• Position count and pitch: Both main and substitute parts must maintain 22 positions at 0.200" (5.08mm) spacing to ensure PCB footprint compatibility
• Mating orientation: Horizontal with board orientation is required for mechanical fit
• Mounting type: Through-hole mounting must be preserved
• Electrical ratings: Voltage (300 V) and current capacity must meet or exceed application requirements
• Wire gauge compatibility: Acceptable wire sizes must overlap with the application's wiring specification
• Interlocking feature: Side interlocking is maintained across all variants

The Weidmüller 1330930000 qualifies as a substitute based on these parameters. While it introduces improvements in current rating, temperature range, and termination method, the core mechanical and electrical compatibility remains within acceptable substitution criteria.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1330930000 is the designated substitute for the obsolete 995171 model. Selection should be based on the following factors:

Product Status: The 995171 is obsolete with no ongoing manufacturing. The 1330930000 is active and maintains full production availability, making it the appropriate choice for new designs and replacement applications.

Compliance: The 1330930000 carries RoHS compliance certification, whereas the 995171 status is not applicable. For applications subject to RoHS requirements, the 1330930000 is the only compliant option.

Regulatory Alignment: Both parts maintain REACH Unaffected status and EAR99 ECCN classification, ensuring consistent regulatory treatment.

Electrical Performance: The 1330930000 provides enhanced current capacity (20 A versus 15 A) and extended operating temperature range (-50°C to 120°C versus -20°C to 100°C), offering improved performance margins for demanding applications.

Termination Method: The transition from screw-based to screwless push-in termination in the 1330930000 represents a design evolution. Assembly procedures will differ; however, both methods achieve equivalent electrical and mechanical connection integrity.

Wire Gauge Consideration: The 1330930000 accepts 12-24 AWG wire, which is a subset of the 995171's 12-26 AWG range. Applications using 25-26 AWG wire require verification that the substitute's range is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the 1330930000 be used as a direct replacement for the 995171 in existing PCB designs?

A: Yes, from a mechanical and electrical standpoint. Both parts share identical 22-position configuration, 0.200" (5.08mm) pitch, and horizontal through-hole mounting. PCB footprints are compatible. However, the termination method differs (screw versus screwless), requiring assembly procedure updates.

Q: What is the impact of the wire gauge difference between the two parts?

A: The 995171 accepts 12-26 AWG wire, while the 1330930000 accepts 12-24 AWG. If your application uses 25-26 AWG conductors, the substitute cannot accommodate these sizes. Verify wire gauge requirements before substitution.

Q: Does the color difference (black versus orange) affect functionality?

A: No. Color is a visual identifier only and does not impact electrical or mechanical performance. The color change reflects the design evolution between the Omnimate LP and Omnimate LMF series.

Q: Are there any assembly or installation differences?

A: Yes. The 995171 uses screw-clamping termination requiring a screwdriver and torque specification (0.5-0.6 Nm). The 1330930000 uses screwless push-in termination, eliminating the need for torque tools. Assembly procedures must be updated accordingly.

Q: Is the 1330930000 suitable for applications requiring the full -20°C to 100°C temperature range of the 995171?

A: Yes. The 1330930000 operates across -50°C to 120°C, which fully encompasses the 995171's temperature range. The substitute provides extended temperature capability.

Q: What is the significance of RoHS compliance on the 1330930000?

A: RoHS compliance indicates the part meets Restriction of Hazardous Substances requirements, restricting lead and other hazardous materials. This is mandatory for many regulated industries and markets. The 995171's "not applicable" status may limit its use in RoHS-regulated applications.

Q: Can both parts be used interchangeably in the same production run?

A: Not recommended. While electrically and mechanically compatible, the different termination methods and assembly procedures create process complexity. Standardizing on the 1330930000 for new production is the preferred approach.
