Weidmüller 995151 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Weidmüller 995151 is a 23-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 compatible substitute components essential for ongoing system maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Weidmüller 995151 is determined by strict alignment of the following critical parameters:

• Position count and pitch: Both main and substitute parts must maintain 23 positions at 0.200" (5.08mm) spacing to ensure PCB footprint compatibility
• Mating orientation and mounting: Horizontal with board orientation and through-hole mounting are non-negotiable for mechanical fit
• Electrical ratings: Voltage rating of 300 V is maintained across all parts; current rating may be equal or higher
• Wire gauge compatibility: Substitute parts must accommodate the wire sizes specified for the application
• Interlocking feature: Side interlocking capability is preserved for mechanical stability
• Contact material and plating: Copper alloy with tin plating ensures consistent electrical performance and corrosion resistance

The Weidmüller 1330940000 qualifies as a substitute based on these parameters, with improvements in current capacity, temperature range, and product status.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1330940000 is the qualified substitute for the obsolete Weidmüller 995151. Selection is based on the following engineering criteria:

Mechanical Compatibility: Both parts maintain identical position count (23), pitch (5.08mm), mating orientation, and through-hole mounting, ensuring direct PCB footprint compatibility without layout modifications.

Electrical Performance: The substitute part maintains the 300 V voltage rating and increases current capacity from 15 A to 20 A, providing enhanced performance margin for the same electrical application space.

Product Status and Compliance: The 1330940000 is an active product with RoHS compliance certification, whereas the 995151 is obsolete. This transition ensures long-term supply chain viability and regulatory alignment for new designs and production continuity.

Operating Environment: The substitute part extends the operating temperature range from -20°C to -50°C at the lower end and from 100°C to 120°C at the upper end, accommodating broader environmental conditions.

Wire Termination Difference: The main part uses screw-clamping termination, while the substitute employs screwless push-in spring termination. This represents a functional improvement in assembly speed and consistency, though assembly procedures must be updated accordingly.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1330940000 be used as a direct replacement for the 995151 on existing PCBs?

A: Yes, from a mechanical and electrical standpoint. Both parts share identical position count, pitch, mating orientation, and through-hole mounting configuration. However, the wire termination method differs: the 995151 uses screw clamping, while the 1330940000 uses push-in spring termination. Assembly procedures and operator training must be updated accordingly.

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

A: The 995151 accepts 12-26 AWG wire, while the 1330940000 accepts 12-24 AWG wire. If your application uses 25 or 26 AWG wire, the substitute part cannot accommodate these sizes. Verify wire gauge specifications in your design before substitution.

Q: Does the higher current rating of the 1330940000 affect compatibility?

A: No. The 20 A rating of the substitute part is equal to or exceeds the 15 A requirement of the original part. This provides additional performance margin without creating compatibility issues.

Q: Are there compliance differences between the two parts?

A: Yes. The 1330940000 is RoHS compliant, while the 995151 is not applicable for RoHS. Both parts maintain REACH Unaffected status and EAR99 export classification. For new designs subject to RoHS requirements, the 1330940000 is the appropriate choice.

Q: What is the significance of the extended operating temperature range in the substitute part?

A: The 1330940000 operates from -50°C to 120°C compared to the 995151's -20°C to 100°C range. This expanded range accommodates more demanding thermal environments without component derating or failure risk.

Q: Are both parts available in the same packaging?

A: The 995151 is listed with no specified packaging designation, while the 1330940000 is supplied in bulk packaging. Verify packaging requirements for your procurement and assembly processes.
