Weidmüller 995158 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Weidmüller 995158 is a 9-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 is classified as obsolete. Due to its discontinued status, identifying functionally equivalent substitute parts is essential for ongoing system maintenance, repair, and new design implementations where this terminal block specification is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 995158 is determined by the following critical parameters:

• Pitch and Position Count: Must maintain 0.200" (5.08mm) pitch with 9 positions per level to ensure PCB footprint compatibility
• Mating Orientation: Must be horizontal with board configuration for mechanical fit
• Mounting Type: Must be through-hole to match existing PCB design
• Interlocking Feature: Side interlocking capability must be preserved for connector stability
• Electrical Ratings: Current and voltage ratings must meet or exceed the original specification (15 A, 300 V minimum)
• Wire Gauge Compatibility: Must accommodate the wire gauge range or a subset thereof

The substitute part Weidmüller 1330790000 meets these core substitution criteria while offering enhanced electrical performance and active product status.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1330790000 is a direct functional substitute for the 995158 based on the following engineering criteria:

Mechanical Compatibility: Both parts maintain identical pitch (5.08mm), position count (9), and through-hole mounting configuration, ensuring PCB footprint compatibility without layout modifications.

Electrical Performance: The substitute part exceeds the original specification with a 20 A current rating versus 15 A, while maintaining the same 300 V voltage rating. This provides additional design margin for applications requiring the original 15 A capacity.

Product Status and Compliance: The 1330790000 is an active product with RoHS compliance certification, whereas the 995158 is obsolete. For new designs and long-term supply chain stability, the substitute part is the preferred selection.

Operating Temperature Range: The substitute extends the operating temperature range to -50°C ~ 120°C compared to the original -20°C ~ 100°C, providing broader environmental applicability.

Wire Gauge Consideration: The substitute accepts 12-24 AWG wire, which covers the majority of the original 12-26 AWG range. Applications requiring 25-26 AWG wire must be evaluated individually.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1330790000 be used as a direct replacement for the 995158 in existing designs?

A: Yes, for applications using wire gauges 12-24 AWG. The 1330790000 maintains identical pitch, position count, and through-hole mounting configuration. If your design uses 25-26 AWG wire, verify that the substitute's 12-24 AWG range is acceptable for your application.

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

A: The 995158 uses screw-clamping termination with a torque specification of 0.5-0.6 Nm, while the 1330790000 uses screwless push-in spring termination. Both achieve equivalent electrical and mechanical performance but differ in assembly methodology.

Q: Does the higher current rating of the 1330790000 affect compatibility?

A: No. A higher current rating is a performance enhancement that does not compromise compatibility. Applications designed for 15 A operation will function correctly with the 20 A rated substitute.

Q: Are there packaging differences between these parts?

A: The 995158 is supplied in standard packaging, while the 1330790000 is supplied in bulk packaging. Verify bulk packaging requirements align with your procurement and handling procedures.

Q: Is the 1330790000 suitable for applications requiring the full -20°C ~ 100°C temperature range of the original?

A: Yes. The 1330790000 operating range of -50°C ~ 120°C fully encompasses the original specification, making it suitable for all temperature conditions where the 995158 was used.

Q: What is the significance of RoHS compliance for the substitute part?

A: RoHS compliance indicates the 1330790000 meets European Union restrictions on hazardous substances. This is relevant for products destined for EU markets or applications with RoHS requirements. The original 995158 lists RoHS status as not applicable due to its obsolete classification.
