Weidmüller 995143 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Weidmüller 995143 is a 15-position wire-to-board terminal block with 0.200" (5.08mm) pitch, designed for horizontal mounting with through-hole PCB connection. This component belongs to the Omnimate LP series and is classified as obsolete. Due to its obsolete status, identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs or system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 995143 is determined by the following critical parameters:

• Pitch and Position Count: Must maintain 0.200" (5.08mm) pitch with 15 positions per level to ensure PCB footprint compatibility
• Mating Orientation and Mounting: Must be horizontal with board orientation and through-hole mounting type
• Electrical Ratings: Voltage rating of 300 V is mandatory; current rating must meet or exceed 15 A
• Wire Gauge Compatibility: Must accommodate wire gauges within or overlapping the 12-26 AWG range
• Mechanical Interface: Side interlocking feature and orange color indicate mechanical compatibility requirements
• Contact Material: Copper alloy with tin plating ensures electrical performance consistency

The Weidmüller 1330850000 qualifies as a substitute based on these parameters. While it introduces improvements in current capacity, temperature range, and wire termination technology, it maintains the core mechanical and electrical compatibility requirements.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1330850000 is the qualified substitute for the obsolete 995143 terminal block. Selection between these parts should be based on the following factors:

For Continued Use of 995143: Existing inventory of 802 units is available. This part remains suitable for applications where the specific screw-based termination method and original specifications are required and where component availability is not a constraint.

For New Designs or Replenishment: The Weidmüller 1330850000 is the recommended choice. This part is active in production with 894 units in stock, ensuring long-term availability. It provides enhanced electrical performance (20 A current rating versus 15 A), extended operating temperature range (-50°C to 120°C versus -20°C to 100°C), and RoHS compliance. The screwless push-in termination technology offers improved assembly efficiency compared to the screw-clamping method of the 995143.

Both parts maintain identical pitch, position count, mating orientation, mounting type, voltage rating, and mechanical interface characteristics. The 1330850000 accommodates wire gauges 12-24 AWG, which overlaps with the 995143 range of 12-26 AWG for the majority of typical applications.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1330850000 be used as a direct replacement for the 995143 in existing PCB designs?

A: Yes. Both parts share identical pitch (0.200" / 5.08mm), position count (15), mating orientation (horizontal with board), and through-hole mounting configuration. PCB footprints designed for the 995143 are mechanically compatible with the 1330850000.

Q: What is the difference in wire termination between these two parts?

A: The 995143 uses screw-based clamping with a tension sleeve mechanism, requiring manual torque application (0.5-0.6 Nm). The 1330850000 employs screwless push-in spring termination, eliminating the need for torque tools and reducing assembly time.

Q: Are there wire gauge limitations when substituting the 1330850000 for the 995143?

A: The 995143 accepts 12-26 AWG wire, while the 1330850000 accepts 12-24 AWG wire. For applications using 25-26 AWG wire, the 995143 specifications must be retained. For 12-24 AWG applications, both parts are compatible.

Q: Does the 1330850000 meet modern regulatory requirements?

A: Yes. The 1330850000 is RoHS compliant and REACH unaffected. The 995143 is classified as not applicable for RoHS status due to its obsolete designation. For new production requiring regulatory compliance, the 1330850000 is the appropriate selection.

Q: What is the current rating difference, and does it affect substitution suitability?

A: The 995143 is rated for 15 A, while the 1330850000 is rated for 20 A. The higher current rating of the substitute part does not create compatibility issues; it provides additional margin for applications operating at or near the original 15 A specification.

Q: Are the operating temperature ranges compatible?

A: The 995143 operates from -20°C to 100°C, while the 1330850000 operates from -50°C to 120°C. The substitute part's extended temperature range is a superset of the original specification, making it suitable for applications within the original temperature window and for designs requiring expanded thermal performance.
