Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 2-284541-0 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Number of Positions: 20
• Pitch: 0.150" (3.81mm)
• Header Orientation: 90°, Right Angle
• Mounting Type: Through Hole
• Termination Style: Solder
• Voltage - UL: 300 V
• Material Flammability Rating: UL94 V-0

Allowable Variation Parameters:

• Current - UL: Substitute must meet or exceed 11 A requirement
• Operating Temperature Range: Substitute must encompass or exceed the -40°C to 110°C range
• Shrouding Configuration: Substitute may differ (4-side vs. 2-side shrouding) provided mechanical fit and electrical isolation are maintained
• Contact Material: Phosphor Bronze or Brass are acceptable alternatives
• Housing Material: Polyamide (PA66) or Thermoplastic are acceptable alternatives

The On Shore Technology Inc. OSTVE203051 meets all critical matching parameters with allowable variations in shrouding configuration, contact material, and housing material. However, the current rating of 8 A (UL) is below the original specification of 11 A, and the operating temperature range of -30°C to 105°C is narrower than the original -40°C to 110°C range.

Engineering Selection Recommendations

TE Connectivity 2-284541-0 (Original Part):

• Product Status: Obsolete
• Compliance: Material Flammability Rating UL94 V-0; ECCN EAR99
• Availability: 772 Pcs New Original In Stock
• Recommendation: Original part remains available for existing designs with established performance history and compliance documentation.

On Shore Technology OSTVE203051 (Substitute Part):

• Product Status: Active
• Compliance: Material Flammability Rating UL94 V-0; RoHS3 Compliant; REACH Unaffected; ECCN EAR99
• Availability: 1033 Pcs New Original In Stock
• Recommendation: Suitable for new designs and procurement requiring an active product with current regulatory compliance. Selection requires evaluation of the following deviations:
  • Current rating reduced from 11 A to 8 A
  • Operating temperature range narrowed from -40°C to 110°C to -30°C to 105°C
  • Shrouding configuration changed from 4-side to 2-side
  • Contact tail length increased from 0.134" to 0.177"
  • Insulation height increased from 0.285" to 0.303"

Applications operating at currents exceeding 8 A or temperatures below -30°C or above 105°C require verification of circuit performance with the substitute part specifications.

Frequently Asked Questions (FAQ)

Q: Can the On Shore Technology OSTVE203051 directly replace the TE Connectivity 2-284541-0 in all applications?

A: Direct replacement is not universal. The OSTVE203051 has a reduced current rating of 8 A compared to the original 11 A specification and a narrower operating temperature range (-30°C to 105°C versus -40°C to 110°C). Applications operating within the OSTVE203051 specifications are compatible. Applications requiring the full 11 A current capacity or extended temperature range require alternative solutions.

Q: What is the significance of the shrouding configuration difference (4-side vs. 2-side)?

A: The original TE Connectivity 2-284541-0 features 4-side shrouding, providing enhanced electrical isolation and mechanical protection on all sides. The On Shore Technology OSTVE203051 features 2-side shrouding, reducing the shrouding coverage. This difference affects the degree of electrical isolation and mechanical robustness. PCB layout and adjacent component placement must be evaluated to determine if 2-side shrouding is acceptable for the intended application.

Q: Are there dimensional compatibility concerns between these parts?

A: Yes. The contact tail length differs (0.134" versus 0.177") and the insulation height differs (0.285" versus 0.303"). These dimensional variations may affect PCB footprint compatibility, solder joint formation, and clearance to adjacent components. PCB design verification is required before substitution.

Q: What is the impact of the contact material change from Phosphor Bronze to Brass?

A: Both Phosphor Bronze and Brass are acceptable contact materials for terminal block applications. Brass provides adequate electrical conductivity and contact reliability for the specified voltage and current parameters. The material change does not introduce electrical incompatibility within the specified operating conditions.

Q: Does the On Shore Technology OSTVE203051 meet current regulatory requirements?

A: Yes. The OSTVE203051 is RoHS3 Compliant and REACH Unaffected, meeting current regulatory standards. The original TE Connectivity 2-284541-0 has RoHS Status listed as "Not applicable" and REACH Status as "Vendor Undefined," indicating it predates current regulatory frameworks. For new designs subject to RoHS3 and REACH compliance requirements, the OSTVE203051 is the appropriate selection.

Q: What is the current availability status of both parts?

A: The TE Connectivity 2-284541-0 (obsolete) has 772 Pcs New Original In Stock. The On Shore Technology OSTVE203051 (active) has 1033 Pcs New Original In Stock. The active status and higher inventory of the OSTVE203051 support long-term procurement planning for new designs.

Q: Are there applications where the TE Connectivity 2-284541-0 cannot be substituted?

A: Yes. Applications requiring current capacity exceeding 8 A, operating temperatures below -30°C or above 105°C, or requiring 4-side shrouding for specific isolation or mechanical requirements cannot use the OSTVE203051 as a direct substitute. Alternative terminal block solutions must be evaluated for these applications.
