Weidmüller 1521860000 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Weidmüller 1521860000 is a 2-position terminal block header with male pins, shrouded design, and 5.08mm pitch for vertical through-hole mounting. This component is classified as obsolete, making identification of equivalent substitute parts essential for ongoing system maintenance and new design implementations. The part operates within IEC ratings of 12A at 250V and UL ratings of 15A at 300V, with an operating temperature range of -20°C to 100°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 1521860000 is determined by the following critical parameters:

• Connector Type & Configuration: Header with male pins, shrouded (2 side), 2 positions
• Pitch & Spacing: 0.200" (5.08mm) pitch for mechanical and electrical compatibility
• Mounting Method: Through-hole solder termination
• Electrical Performance: Current and voltage ratings must meet or exceed IEC 12A/250V and UL 15A/300V specifications
• Physical Dimensions: Insulation height of 0.472" (12.00mm) and contact tail length within acceptable range
• Material & Compliance: UL94 V-0 flammability rating, RoHS compliance, and copper alloy contacts

The identified substitute parts maintain these core parameters while offering improved product status (active availability) and enhanced electrical performance in certain ratings.

Parameter Comparison

Engineering Selection Recommendations

Weidmüller 1146320000 is the primary substitute within the Omnimate SL series. This part maintains identical mechanical compatibility (2 positions, 5.08mm pitch, vertical through-hole) and exceeds the electrical performance of the obsolete 1521860000 with IEC ratings of 24A at 400V. The extended operating temperature range (-50°C to 100°C) provides additional thermal margin. Housing material differs (glass-filled polyamide versus PBT), and contact tail length is shorter (3.20mm versus 4.50mm), requiring verification of PCB pad layout compatibility. Both parts carry RoHS compliance and UL94 V-0 flammability rating.

TE Connectivity 282825-2 (Buchanan series) provides cross-manufacturer substitution with identical mechanical configuration and UL electrical ratings (15A at 300V). This part features an extended operating temperature range (-40°C to 110°C) and includes side stacking capability. Housing material is polyamide (PA66) nylon 6/6. Contact tail length (4.60mm) falls between the original and Weidmüller alternative. ROHS3 compliance and active product status support long-term availability. IEC current rating is not specified for this part.

Both substitutes are currently in active production status, ensuring supply chain continuity compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1146320000 directly replace the 1521860000 on existing PCBs?

A: Mechanical compatibility is maintained for the connector interface (2 positions, 5.08mm pitch, vertical orientation). However, the contact tail length differs (3.20mm versus 4.50mm), requiring verification that PCB pad spacing and solder joint geometry remain within acceptable tolerances. Housing material change from PBT to glass-filled polyamide may affect mechanical stress characteristics in vibration-prone applications.

Q: What are the electrical performance differences between substitutes?

A: The Weidmüller 1146320000 provides enhanced IEC ratings (24A at 400V versus 12A at 250V), offering greater current and voltage capacity. The TE Connectivity 282825-2 maintains the original UL rating (15A at 300V) but does not specify IEC current rating. Both substitutes meet or exceed the original part's UL electrical specifications.

Q: Are there temperature range considerations for substitution?

A: The original part operates from -20°C to 100°C. The Weidmüller 1146320000 extends the lower limit to -50°C, and the TE Connectivity 282825-2 extends both limits (-40°C to 110°C). Applications requiring operation below -20°C or above 100°C benefit from these extended ranges.

Q: How do housing material differences affect performance?

A: The original uses polybutylene terephthalate (PBT), while substitutes use polyamide (PA) or glass-filled polyamide. Both materials maintain UL94 V-0 flammability rating. Polyamide variants offer improved impact resistance and lower moisture absorption, while PBT provides superior dimensional stability. Material selection depends on specific environmental and mechanical stress requirements.

Q: Is cross-manufacturer substitution (TE Connectivity 282825-2) recommended?

A: Yes, the TE Connectivity 282825-2 maintains full mechanical and electrical compatibility with identical pitch, position count, and UL ratings. Active product status and ROHS3 compliance support long-term supply availability. The side stacking feature provides additional design flexibility not present in the original part.

Q: What compliance certifications are maintained across all parts?

A: All three parts carry UL94 V-0 flammability rating, RoHS compliance (RoHS or ROHS3), and identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications. Moisture sensitivity level remains 1 (Unlimited) across all variants.
