Weidmüller 1623920000 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Weidmüller 1623920000 is a 12-position terminal block header with male pins, shrouded on two sides, featuring 0.300" (7.62mm) pitch and 90° right-angle through-hole mounting. This component 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 eligibility for the Weidmüller 1623920000 is determined by the following critical parameters:

• Position Count & Pitch: Must be 12 positions at 0.300" (7.62mm) spacing to ensure PCB footprint compatibility
• Connector Type & Orientation: Must be male pin header with 90° right-angle configuration and two-side shrouding for mechanical fit and polarization
• Termination & Mounting: Solder termination with through-hole mounting required for assembly process compatibility
• Material & Flammability: UL94 V-0 rated housing material ensures compliance with fire safety standards
• Contact Specifications: Copper alloy contacts with tin mating finish provide electrical performance and corrosion resistance

The TE Connectivity AMP Connectors 1-282965-2 (Buchanan series) meets all critical substitution criteria, with documented differences in operating temperature range, housing material composition, and electrical ratings that remain within acceptable application parameters.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 1-282965-2 serves as a direct functional substitute for the obsolete Weidmüller 1623920000 based on the following engineering criteria:

Mechanical Compatibility: Both components share identical pitch (0.300"/7.62mm), position count (12), orientation (90° right-angle), and shrouding configuration (2-side). PCB footprint compatibility is confirmed.

Electrical Performance: The TE part maintains identical voltage rating (300V UL) and exceeds the current rating (15A vs. 10A UL), providing equivalent or superior electrical capacity for the same application space.

Material & Safety Compliance: Both components feature UL94 V-0 flammability ratings. The TE part uses PA66 nylon housing versus PBT in the Weidmüller; both materials meet the same fire safety standard and are suitable for equivalent thermal environments within their respective operating ranges.

Product Availability: The TE Connectivity part is actively manufactured, ensuring supply chain continuity for the obsolete Weidmüller component.

Regulatory Status: The TE part carries RoHS compliance certification, meeting modern regulatory requirements for new designs and manufacturing environments.

Design Consideration: The TE part features a shorter contact tail length (0.138" vs. 0.177"), which may require PCB pad layout verification for solder joint formation. Insulation height difference (0.329" vs. 0.335") is negligible for mechanical clearance.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-282965-2 be used as a direct replacement on existing PCBs designed for the Weidmüller 1623920000?

A: Yes, with one design consideration. The shorter contact tail length (4.60mm vs. 4.50mm) requires verification that PCB pad depth and solder joint geometry remain adequate. The pitch, position count, and mounting footprint are identical. Recommend pad layout review before production implementation.

Q: What is the impact of different housing materials (PBT vs. PA66)?

A: Both materials achieve UL94 V-0 flammability rating. PBT (Weidmüller) offers slightly higher continuous operating temperature (130°C vs. 110°C). PA66 (TE Connectivity) provides equivalent fire safety and is suitable for applications within its -40°C to 110°C operating range. Material selection depends on specific thermal environment requirements.

Q: Are there electrical performance differences between these components?

A: The TE part is rated for 15A (UL) versus 10A (UL) for the Weidmüller, representing a 50% higher current capacity. Voltage rating remains identical at 300V (UL). For applications operating at or near the original 10A specification, the TE part provides additional design margin.

Q: Why is the Weidmüller part obsolete?

A: Product status reflects manufacturer discontinuation of the Omnimate SL series. The TE Connectivity Buchanan series provides equivalent functionality with active manufacturing support and modern compliance certifications (RoHS).

Q: Does the TE part meet RoHS requirements?

A: Yes. The TE Connectivity 1-282965-2 is RoHS compliant. The Weidmüller part's RoHS status is not specified in available documentation.

Q: What is the significance of the insulation height difference (0.335" vs. 0.329")?

A: The 0.006" (0.15mm) difference is negligible for mechanical clearance and component spacing on standard PCB layouts. This parameter does not affect substitution suitability.

Q: Can I mix Weidmüller and TE Connectivity parts in the same assembly?

A: Yes. Both components share identical pitch and position configuration, allowing mixed use within the same PCB design. However, standardizing on a single part number is recommended for inventory management and assembly process consistency.
