Weidmüller 999365 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Weidmüller 999365 is an 18-position wire-to-board terminal block with 45° (135°) angle orientation and 0.197" (5.00mm) pitch for through-hole PCB mounting. This component belongs to the Omnimate LM 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

Substitute parts for the Weidmüller 999365 are identified based on the following critical parameters that determine functional equivalence:

• Position Count: 18 positions (exact match required)
• Pitch Specification: 0.197" (5.00mm) center-to-center spacing
• Mating Orientation: 45° (135°) angle with board
• Mounting Configuration: Through-hole PCB mounting
• Connector Type: Wire-to-board terminal block

The Assmann WSW Components A-TB500-TP18 satisfies all these core substitution criteria. Both components share identical mechanical and electrical interface specifications, enabling direct functional replacement in applications requiring this terminal block configuration.

Parameter Comparison

Engineering Selection Recommendations

The Assmann WSW Components A-TB500-TP18 is the designated substitute for the obsolete Weidmüller 999365. Selection rationale is based on:

• Product Status Alignment: The A-TB500-TP18 maintains active production status, ensuring long-term availability and supply chain continuity.
• Compliance Certifications: Both components share identical ECCN (EAR99) and HTSUS classifications, maintaining regulatory consistency.
• Moisture Sensitivity: Both components carry MSL 1 (Unlimited) rating, indicating equivalent environmental handling requirements.
• Mechanical Compatibility: Identical pitch, position count, and mating orientation ensure direct PCB layout compatibility without redesign.

The A-TB500-TP18 is suitable for applications where the Weidmüller 999365 was originally specified, provided that color variation (gray versus black) does not present functional or aesthetic constraints.

Frequently Asked Questions (FAQ)

Q: Can the Assmann A-TB500-TP18 be used as a direct replacement for the Weidmüller 999365?

A: Yes. Both components share identical mechanical and electrical interface specifications: 18 positions, 0.197" (5.00mm) pitch, 45° (135°) mating orientation, and through-hole mounting. Direct substitution is supported without PCB layout modification.

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

A: The Weidmüller 999365 is obsolete, while the Assmann A-TB500-TP18 is in active production. The A-TB500-TP18 also provides additional documented specifications including current rating (10 A), voltage rating (300 V), wire gauge compatibility (12-24 AWG), and operating temperature range (-40°C ~ 115°C).

Q: Are there packaging differences between these components?

A: The Weidmüller 999365 packaging specification is not provided. The Assmann A-TB500-TP18 is supplied in bulk packaging. Verify packaging requirements for your procurement process.

Q: Do both components have the same moisture sensitivity requirements?

A: Yes. Both components carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: Are there color considerations for substitution?

A: The Weidmüller 999365 is black; the Assmann A-TB500-TP18 is gray. If color matching is a functional requirement for your application, this difference must be evaluated against your design specifications.
