Weidmüller 995019 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Weidmüller 995019 is a 21-position wire-to-board terminal block with 5.00mm pitch, designed for horizontal mounting through PCB holes. This component features screw-clamping wire termination with side interlocking capability, supporting 15A at 300V across wire gauges 12-26 AWG. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations where this series is no longer available.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Weidmüller 995019 is determined by strict alignment of the following parameters:

• Position count and pitch: Both main and substitute parts must maintain 21 positions at 0.197" (5.00mm) pitch to ensure PCB layout compatibility
• Mating orientation: Horizontal with board orientation is required for mechanical fit
• Electrical ratings: Minimum current and voltage ratings must meet or exceed the original specification (15A, 300V)
• Wire gauge compatibility: The substitute must accommodate the wire gauge range of the application
• Mounting method: Through-hole mounting is mandatory for PCB integration
• Interlocking feature: Side interlocking capability must be present for mechanical stability
• Contact material and plating: Copper alloy with tin plating ensures electrical performance and corrosion resistance

The TE Connectivity AMP Connectors part 2-1986711-1 meets these substitution criteria with enhanced electrical performance and active product status.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 2-1986711-1 serves as a direct functional substitute for the obsolete Weidmüller 995019. Both components share identical position count, pitch, mating orientation, and mounting method, ensuring mechanical and electrical compatibility at the PCB interface.

The TE Connectivity part offers enhanced specifications: 16A current rating versus 15A, extended operating temperature range (-40°C to 110°C versus -20°C to 100°C), and broader wire gauge accommodation (12-30 AWG versus 12-26 AWG). The substitute achieves ROHS3 compliance, whereas the original part status is not applicable. Both components maintain 300V voltage rating and copper alloy tin-plated contacts.

The primary functional difference is the wire termination method: the original uses screw-clamping with tension sleeve, while the substitute employs screwless push-button clamping. This termination difference requires evaluation against specific assembly and maintenance procedures in the target application.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 2-1986711-1 replace the Weidmüller 995019 in existing designs?

A: Yes, the TE Connectivity part maintains identical position count (21), pitch (5.00mm), mating orientation (horizontal with board), voltage rating (300V), and through-hole mounting. The mechanical footprint and electrical interface are compatible. However, the termination method differs (screwless push-button versus screw-clamping), which may affect assembly procedures and maintenance protocols.

Q: What are the key compatibility factors for substitution?

A: The critical parameters are 21-position count, 5.00mm pitch, horizontal board orientation, through-hole mounting, 300V voltage rating, and side interlocking feature. Both parts meet these requirements. Wire gauge range and current rating must be evaluated against the specific application load.

Q: Does the TE Connectivity part support the same wire gauge range?

A: The TE Connectivity 2-1986711-1 supports 12-30 AWG, which encompasses the original 12-26 AWG range. Applications using wire gauges 12-26 AWG are fully compatible. The extended range to 30 AWG provides additional flexibility for finer wire applications.

Q: What is the impact of the different wire termination methods?

A: The Weidmüller 995019 uses screw-clamping with tension sleeve, requiring torque application (0.5-0.6 Nm). The TE Connectivity 2-1986711-1 uses screwless push-button clamping, eliminating torque specification requirements. This affects assembly time, tooling requirements, and field maintenance procedures. Both methods provide equivalent electrical and mechanical security.

Q: Are there compliance differences between the two parts?

A: The TE Connectivity part is ROHS3 compliant with MSL rating of 1 (unlimited), while the Weidmüller part shows not applicable status for RoHS. The TE Connectivity part has vendor-undefined REACH status versus REACH unaffected for the original. Both carry EAR99 ECCN classification and identical HTSUS code 8536.90.4000.

Q: What is the current rating difference, and does it matter?

A: The TE Connectivity part is rated 16A versus 15A for the original. For applications operating at or below 15A, this difference is not a limiting factor. For applications approaching 16A, the substitute provides additional margin.
