Weidmüller 1522010000 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Weidmüller 1522010000 is a 4-position terminal block header with male pins, shrouded on two sides, featuring a 0.200" (5.08mm) pitch for vertical through-hole mounting. This component is part of the Omnimate SL series and is designed for solder termination applications requiring IEC ratings of 12A at 250V and UL ratings of 15A at 300V.

The 1522010000 has reached obsolete product status. Identifying functionally equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades.

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 1522010000 is determined by the following critical parameters:

Position Count & Pitch: 4 positions at 0.200" (5.08mm) spacing
Connector Type & Orientation: Male pin header, vertical orientation, shrouded on two sides
Electrical Ratings: Minimum UL voltage rating of 300V; IEC current rating of 12A or higher
Mounting Method: Through-hole solder termination
Contact Finish: Tin plating for corrosion resistance and solderability
Operating Temperature: Functional range of -20°C to 100°C or broader

The On Shore Technology Inc. OSTOQ045350 meets these substitution criteria. Both components share identical position count, pitch, connector type, shrouding configuration, and vertical orientation. Both are rated for 300V UL and feature tin-plated contacts suitable for solder termination. The OSTOQ045350 operates across a wider temperature range (-30°C to 105°C) and maintains electrical compatibility with the original design.

Engineering Selection Recommendations

The On Shore Technology OSTOQ045350 is the qualified substitute for the obsolete Weidmüller 1522010000. Selection is based on the following engineering factors:

Product Status: The OSTOQ045350 maintains active production status, ensuring long-term component availability and supply chain continuity compared to the obsolete 1522010000.

Electrical Compliance: Both components meet identical UL voltage requirements (300V) and are rated for solder termination. The OSTOQ045350 supports the required electrical performance without derating.

Regulatory Compliance: The OSTOQ045350 is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards. Both components share identical ECCN (EAR99) and HTSUS classifications.

Mechanical Compatibility: Identical pitch (5.08mm), position count (4), orientation (vertical), and shrouding configuration (2-side) ensure direct mechanical interchangeability in PCB layouts and connector assemblies.

Temperature Performance: The OSTOQ045350 operates across a wider temperature range (-30°C to 105°C) compared to the original specification (-20°C to 100°C), providing enhanced thermal margin for demanding applications.

Frequently Asked Questions (FAQ)

Q: Can the OSTOQ045350 be used as a direct replacement for the 1522010000 in existing designs?

A: Yes. Both components share identical pitch (5.08mm), position count (4), connector type (male pin header), shrouding (2-side), and orientation (vertical). PCB footprints and connector mating interfaces are mechanically compatible. Electrical ratings (300V UL) are equivalent.

Q: What are the key differences between these two parts?

A: The primary differences are product status (1522010000 is obsolete; OSTOQ045350 is active), operating temperature range (OSTOQ045350 supports -30°C to 105°C versus -20°C to 100°C), contact material (copper alloy versus brass), and housing material (PBT versus thermoplastic). The OSTOQ045350 is ROHS3 compliant.

Q: Are there any electrical performance differences?

A: Both components are rated for 300V UL and feature tin-plated contacts for solder termination. The 1522010000 specifies 12A IEC current rating; the OSTOQ045350 does not specify IEC current in the provided data. Both are suitable for standard signal and low-power applications within the 300V UL envelope.

Q: What is the impact of different contact materials (copper alloy versus brass)?

A: Both copper alloy and brass are standard contact materials for terminal block headers. Tin plating on both materials provides equivalent corrosion resistance and solderability. Material selection does not affect electrical performance or mechanical compatibility in this application.

Q: Is the wider operating temperature range of the OSTOQ045350 significant?

A: The OSTOQ045350 supports operation from -30°C to 105°C compared to -20°C to 100°C for the 1522010000. This extended range provides additional thermal margin and may be beneficial for applications in extreme environments, though both components meet standard industrial temperature requirements.

Q: Are there packaging or inventory considerations?

A: The 1522010000 is listed as obsolete with 708 pieces in stock. The OSTOQ045350 is active production with 1358 pieces available. For new designs and long-term supply assurance, the OSTOQ045350 is the recommended selection.
