Phoenix Contact 1955086 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1955086 is a 7-position terminal block header with male pins, shrouded on 4 sides, designed for 90° right-angle through-hole mounting. This component operates at 12A per position (IEC) and 400V (IEC), with a 0.200" (5.08mm) pitch configuration. The part is active in production and RoHS compliant, making it suitable for industrial control and power distribution applications where reliable electrical connections are required. Substitute parts may be necessary due to inventory constraints, lead time requirements, or packaging preferences while maintaining equivalent electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

The On Shore Technology Inc. OSTOQ075451 qualifies as an equivalent substitute based on the following critical parameters:

• Electrical Compatibility: Both parts maintain 7 positions with 0.200" (5.08mm) pitch spacing, ensuring identical PCB footprint and connector interface compatibility.
• Mechanical Configuration: Both feature male pins with 4-side shrouding and 90° right-angle orientation for identical mounting geometry.
• Termination Method: Both utilize solder termination for through-hole PCB assembly.
• Contact Material: Both employ tin-plated contacts for equivalent mating performance.
• Compliance: Both are RoHS compliant and carry EAR99 ECCN classification.

Differences in housing material (Liquid Crystal Polymer vs. Thermoplastic), contact tail length (2.60mm vs. 4.00mm), and insulation height do not prevent substitution when the PCB design accommodates the OSTOQ075451's physical dimensions. The OSTOQ075451 operates within -40°C to 115°C, which encompasses typical industrial operating ranges.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1955086 is recommended when:

• Original equipment specifications explicitly require Phoenix Contact COMBICON CCA series components
• The application requires UL voltage rating of 300V with IEC rating of 400V
• Material flammability rating UL94 V-0 is a design requirement
• Packaging in Tape & Reel format is preferred for automated assembly

On Shore Technology OSTOQ075451 is recommended when:

• Inventory availability or lead time constraints necessitate an alternative source
• Bulk packaging is acceptable for the assembly process
• The application operates within -40°C to 115°C temperature range
• ROHS3 compliance is required
• The longer contact tail length (4.00mm) and reduced insulation height (4.00mm) are compatible with PCB design specifications

Both parts are active products with established supply chains and carry equivalent electrical certifications for industrial applications.

Frequently Asked Questions (FAQ)

Q: Can OSTOQ075451 be used as a direct replacement for 1955086 on existing PCBs?

A: Electrical compatibility is confirmed through matching pitch, position count, and contact configuration. However, the OSTOQ075451 has a longer contact tail (4.00mm vs. 2.60mm) and lower insulation height (4.00mm vs. 8.61mm). PCB design must accommodate these dimensional differences. Physical clearance verification is required before substitution.

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

A: The 1955086 carries an IEC rating of 12A per position at 400V, while the OSTOQ075451 does not specify IEC current rating. Both maintain 300V UL rating. For applications requiring 12A per position at 400V, the 1955086 is the specified choice.

Q: Are both parts suitable for the same operating temperature range?

A: The 1955086 does not specify an operating temperature range in the provided data. The OSTOQ075451 operates from -40°C to 115°C. Applications with defined temperature requirements should reference the 1955086 datasheet for confirmation of thermal compatibility.

Q: What is the difference in packaging between these parts?

A: The 1955086 is supplied in Tape & Reel (TR) format, suitable for automated pick-and-place assembly. The OSTOQ075451 is supplied in Bulk packaging, requiring manual handling or alternative feeding methods.

Q: Do both parts meet RoHS requirements?

A: Yes. The 1955086 is RoHS Compliant. The OSTOQ075451 is ROHS3 Compliant. Both meet current RoHS standards for lead-free component manufacturing.

Q: What is the significance of the different housing materials?

A: The 1955086 uses Liquid Crystal Polymer (LCP) housing with UL94 V-0 flammability rating. The OSTOQ075451 uses Thermoplastic housing without specified flammability rating. For applications with flammability requirements, the 1955086 is the appropriate selection.
