TE Connectivity AMP Connectors 2-284516-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 2-284516-1 is a 21-position terminal block header with male pins, shrouded on four sides, designed for vertical through-hole mounting with 0.138" (3.50mm) pitch spacing. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system maintenance, repair, and redesign applications.

The primary function of this terminal block header is to provide a secure, solderable connection interface for multi-conductor wire termination in industrial control systems, instrumentation, and power distribution applications. The shrouded design offers mechanical protection and prevents accidental contact with live pins during operation.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 2-284516-1 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Number of positions: 21
• Pitch spacing: 0.138" (3.50mm)
• Header orientation: Vertical
• Type: Header with male pins, shrouded (4 side)
• Mounting type: Through hole
• Termination style: Solder
• Voltage rating: 300 V (UL)
• Material flammability rating: UL94 V-0

Acceptable Variation Parameters:

• Current rating: Substitute must meet or exceed 11 A (UL)
• Operating temperature maximum: Substitute must support at least 110°C
• Contact material: Phosphor bronze or equivalent conductive material
• Housing material: Polyamide variants acceptable
• Contact finish: Tin plating acceptable
• Product status: Active status preferred for ongoing availability

The Amphenol PCD ELXH21500 meets all mandatory matching parameters and exceeds performance specifications in current rating (12 A) and maximum operating temperature (125°C), qualifying it as a direct substitute.

Engineering Selection Recommendations

Primary Substitute: Amphenol PCD ELXH21500

The Amphenol PCD ELXH21500 is the qualified substitute for the obsolete TE Connectivity 2-284516-1. This substitution is based on the following engineering criteria:

Functional Equivalence: Both components share identical electrical and mechanical specifications across all critical parameters: 21-position configuration, 0.138" (3.50mm) pitch, vertical orientation, shrouded male pin design, through-hole mounting, and solder termination. Both maintain 300 V UL voltage rating and UL94 V-0 flammability compliance.

Performance Enhancement: The ELXH21500 provides improved performance margins with a 12 A current rating (versus 11 A) and extended maximum operating temperature of 125°C (versus 110°C). These enhancements ensure compatibility with existing circuit designs while providing additional thermal and electrical headroom.

Compliance and Availability: The ELXH21500 holds active product status with RoHS compliance certification, ensuring long-term availability and regulatory alignment for new designs and system upgrades. The original 2-284516-1 is classified as obsolete, making the ELXH21500 the appropriate choice for component replacement and procurement.

Physical Compatibility: Minor dimensional variations in contact tail length (0.138" versus 0.134") and insulation height (0.360" versus 0.362") are within acceptable tolerances for through-hole PCB mounting and do not affect functional compatibility or mating characteristics.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol PCD ELXH21500 be used as a direct replacement for the TE Connectivity 2-284516-1 in existing assemblies?

A: Yes. The ELXH21500 is a direct functional equivalent with identical electrical ratings (300 V, 11+ A capability), mechanical configuration (21 positions, 3.50mm pitch, vertical orientation), and mounting characteristics (through-hole solder termination). The substitute meets or exceeds all performance specifications of the original component.

Q: What are the key differences between these two terminal block headers?

A: The primary differences are product status (obsolete versus active), manufacturer (TE Connectivity versus Amphenol PCD), contact material (phosphor bronze versus brass), housing material (PA66 versus PA46 polyamide), and minor dimensional variations in contact tail length and insulation height. The ELXH21500 also provides higher current rating (12 A) and extended temperature range (125°C maximum).

Q: Are there any compatibility concerns with PCB mounting or wire termination?

A: No. Both components use identical solder termination style and through-hole mounting methodology. The minor dimensional differences (contact tail length and insulation height) are within standard manufacturing tolerances and do not affect PCB pad layout, hole sizing, or wire gauge compatibility.

Q: Does the Amphenol PCD ELXH21500 meet current regulatory requirements?

A: Yes. The ELXH21500 is RoHS compliant and maintains UL94 V-0 flammability certification. The original 2-284516-1 carries "not applicable" RoHS status, indicating it predates current compliance requirements. The substitute is suitable for applications requiring modern regulatory alignment.

Q: What is the packaging difference between these components?

A: The TE Connectivity 2-284516-1 packaging specification is not defined in available documentation. The Amphenol PCD ELXH21500 is supplied in tray packaging. Confirm packaging requirements with your procurement or assembly department for specific application needs.

Q: Can the ELXH21500 handle the same wire gauge and current loads as the original component?

A: Yes. Both components are rated for 11 A minimum (ELXH21500 rated at 12 A), and both support 300 V UL voltage. Wire gauge compatibility is determined by the mating connector or wire termination method, not by the terminal block header itself. Consult wire gauge specifications for your specific application.

Q: Is the color difference (green versus black) a functional concern?

A: No. Color is a cosmetic identifier only and does not affect electrical performance, thermal characteristics, or mechanical function. The color difference reflects different manufacturing series (Buchanan versus ELXH) but does not impact substitution compatibility.
