TE Connectivity AMP Connectors 2-284512-0 Terminal Block Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 2-284512-0 is a 20 Position Terminal Block Header with male pins, shrouded on four sides, designed for 90° right angle through-hole mounting. This component operates at 300 V UL and 11 A UL current rating with a 0.138" (3.50mm) pitch configuration. The part is classified as obsolete, making identification of equivalent and substitute components necessary for ongoing system maintenance, repair, and redesign applications where continued sourcing of the original part is unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 2-284512-0 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 20
• Pitch: 0.138" (3.50mm)
• Header Orientation: 90°, Right Angle
• Type: Header, Male Pins, Shrouded (4 Side)
• Termination Style: Solder
• Mounting Type: Through Hole

Electrical Compatibility Parameters:

• Voltage - UL: 300 V (minimum requirement)
• Current - UL: 10 A or greater (original part rated 11 A)

Physical and Material Parameters:

• Material Flammability Rating: UL94 V-0
• Contact Mating Finish: Tin

The Weidmüller 1841810000 satisfies all mandatory matching parameters and electrical compatibility requirements. While certain secondary parameters differ (contact material, housing material, operating temperature range, color), these variations do not prevent functional substitution when the primary electrical and mechanical criteria are met.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1841810000 is a direct functional substitute for the obsolete TE Connectivity 2-284512-0 based on electrical and mechanical equivalence. Both components share identical pitch, position count, orientation, and termination methodology. Both meet UL94 V-0 flammability requirements and operate at 300 V UL with current ratings within acceptable tolerance (10 A versus 11 A).

The Weidmüller part offers the advantage of active product status, ensuring continued availability and supply chain reliability. The component is RoHS Compliant, providing compliance with current environmental regulations. The addition of IP10 ingress protection in the Weidmüller design provides enhanced environmental sealing compared to the original part specification.

Minor physical variations exist in contact tail length (0.126" versus 0.134") and insulation height (0.293" versus 0.287"), which fall within acceptable manufacturing tolerances for through-hole solder applications. The operating temperature range of the Weidmüller part (-50°C ~ 100°C) is narrower at the upper limit but extends lower, accommodating most industrial applications.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1841810000 be used as a direct replacement for the TE Connectivity 2-284512-0 in existing designs?

A: Yes. Both components share identical pitch (0.138" / 3.50mm), position count (20), header orientation (90° right angle), connector type (male pins, shrouded 4-side), and termination method (solder through-hole). Electrical ratings are compatible at 300 V UL and 10-11 A UL.

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

A: Contact tail length differs by 0.008" (0.20mm), and insulation height differs by 0.006" (0.14mm). These variations are within standard manufacturing tolerances for terminal block headers and do not affect PCB mounting or electrical performance in standard applications.

Q: Is the Weidmüller part RoHS compliant?

A: Yes. The Weidmüller 1841810000 is RoHS Compliant. The original TE Connectivity part lists RoHS Status as Not Applicable due to its obsolete classification.

Q: What is the operating temperature difference between these parts?

A: The TE Connectivity part operates from -40°C to 110°C. The Weidmüller part operates from -50°C to 100°C. The Weidmüller part extends the lower temperature range by 10°C but has a 10°C lower upper limit. Selection depends on specific application temperature requirements.

Q: Does the Weidmüller part have any additional protective features?

A: The Weidmüller 1841810000 includes IP10 ingress protection, which the original part does not specify. This provides enhanced protection against dust and contact with larger objects.

Q: Are the contact materials compatible in terms of mating performance?

A: Both parts use tin contact mating finish. The TE Connectivity part uses Phosphor Bronze contacts while the Weidmüller part uses Copper Alloy contacts. Both materials are standard for terminal block applications and provide equivalent electrical conductivity and reliability.

Q: What is the current rating difference, and does it affect substitution?

A: The TE Connectivity part is rated at 11 A UL while the Weidmüller part is rated at 10 A UL. For applications operating at or below 10 A, substitution is direct. For applications requiring the full 11 A capacity, design verification is necessary to confirm the 1 A reduction is acceptable.
