Weidmüller 995149 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Weidmüller 995149 is a 21-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 capability. The part is currently obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations where equivalent functionality is required.

Substitute Part Grouping Explanation

Substitution of the Weidmüller 995149 is determined by the following critical parameters that must remain consistent:

Position count and pitch: 21 positions at 0.200" (5.08mm) spacing
Mounting configuration: Horizontal with board, through-hole PCB mounting
Electrical ratings: Minimum 15 A current and 300 V voltage capability
Wire gauge compatibility: Support for 12 AWG minimum wire sizes
Mechanical features: Side interlocking capability for connector stability
Housing and contact materials: Polyamide or equivalent thermoplastic with tin-plated copper contacts

The Weidmüller 1330920000 qualifies as a substitute based on these parameters. While it introduces improvements in current rating (20 A), operating temperature range (-50°C ~ 120°C), and termination method (screwless push-in versus screw-clamping), it maintains all critical compatibility requirements for direct functional replacement.

Engineering Selection Recommendations

The Weidmüller 1330920000 is the qualified substitute for the obsolete 995149 terminal block. Selection of this substitute is supported by the following factors:

Product Status: The 1330920000 is an active product from Weidmüller, ensuring ongoing availability and supply chain continuity compared to the obsolete 995149.

Regulatory Compliance: The 1330920000 carries RoHS compliance certification, meeting current environmental and regulatory requirements for electronic component manufacturing and use in regulated industries.

Electrical Performance: The substitute maintains the 300 V voltage rating and exceeds the original 15 A current specification with a 20 A rating, providing enhanced electrical capacity for the same footprint and pitch.

Mechanical Compatibility: Both components share identical position count (21), pitch spacing (0.200"), mounting orientation (horizontal with board), and through-hole PCB mounting configuration, ensuring direct mechanical interchangeability.

Termination Method Transition: The shift from screw-clamping to screwless push-in termination represents a design modernization that simplifies assembly procedures while maintaining equivalent electrical and mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the 1330920000 be used as a direct replacement for the 995149 in existing PCB designs?

A: Yes. Both components share identical pitch (0.200"), position count (21), mounting type (through-hole), and mating orientation (horizontal with board). PCB footprints designed for the 995149 will accommodate the 1330920000 without modification.

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

A: The main difference is the wire termination method. The 995149 uses screw-clamping with a tension sleeve, while the 1330920000 uses a screwless push-in spring mechanism. The 1330920000 also offers improved current rating (20 A versus 15 A) and extended operating temperature range (-50°C ~ 120°C versus -20°C ~ 100°C).

Q: Are there wire gauge compatibility concerns when substituting?

A: The 995149 supports 12-26 AWG wire, while the 1330920000 supports 12-24 AWG wire. For applications using 25-26 AWG wire, the 1330920000 may not accommodate the full range. Verify wire gauge requirements before substitution.

Q: Does the 1330920000 meet current regulatory requirements?

A: Yes. The 1330920000 is RoHS compliant and carries active product status, meeting current environmental and regulatory standards. The 995149 is obsolete and carries "Not applicable" RoHS status.

Q: Is the packaging format different between these parts?

A: The 995149 is listed with unspecified packaging, while the 1330920000 is supplied in bulk packaging. Confirm packaging and quantity requirements with your supplier for procurement planning.

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

A: Yes, provided wire gauge requirements fall within the 12-24 AWG range supported by both components. The identical pitch, position count, and mounting configuration ensure mechanical and electrical interchangeability within this wire gauge specification.
