TE Connectivity AMP Connectors 2-284539-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 2-284539-1 is a 21 Position Terminal Block Header with male pins, shrouded on four sides, featuring a 0.138" (3.50mm) pitch and 90° right angle orientation for through-hole mounting. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing production and maintenance applications. Substitute parts must maintain electrical and mechanical compatibility while meeting current availability and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2-284539-1 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Core Compatibility Parameters:

• 21 position count
• 0.138" (3.50mm) pitch spacing
• 90° right angle header orientation
• Male pin configuration with four-side shrouding
• Solder termination for through-hole mounting
• 300 V UL voltage rating
• UL94 V-0 flammability classification
• Tin contact mating finish
• Moisture Sensitivity Level 1

The substitute parts ELXH21100 and OQ2112510000G satisfy all core compatibility parameters. Both components maintain identical positional configuration, pitch spacing, orientation, and electrical ratings. Variations in current rating, contact material composition, housing material formulation, and operating temperature maximum do not preclude substitution, as these parameters remain within acceptable ranges for the application category.

Parameter Comparison

Engineering Selection Recommendations

ELXH21100 (Amphenol PCD) is suitable for applications requiring extended operating temperature performance, with a maximum rating of 125°C compared to the original 110°C specification. This part carries active product status and RoHS compliance certification, supporting modern supply chain requirements. Current capacity of 12 A exceeds the original 11 A specification. Packaging is provided in tray format.

OQ2112510000G (Amphenol Anytek) maintains the original operating temperature range of -40°C to 115°C and preserves the green color specification of the original component. This part carries active product status and ROHS3 compliance certification with REACH unaffected status. Current capacity of 10 A is within acceptable tolerance of the original 11 A specification. Packaging is provided in bulk format.

Both substitute parts satisfy all mandatory electrical and mechanical compatibility criteria. Selection between ELXH21100 and OQ2112510000G depends on specific application requirements regarding temperature range, packaging format, and compliance documentation needs.

Frequently Asked Questions (FAQ)

Q: Can ELXH21100 or OQ2112510000G be used as direct replacements for 2-284539-1 in existing designs?

A: Both substitute parts maintain identical positional configuration (21 positions), pitch spacing (0.138" / 3.50mm), header orientation (90° right angle), and electrical ratings (300 V UL). Direct substitution is supported from a functional and mechanical standpoint. Minor variations in contact tail length and insulation height exist but remain within acceptable tolerance ranges for through-hole solder mounting applications.

Q: What are the differences in current rating between the original and substitute parts?

A: The original 2-284539-1 is rated for 11 A UL. ELXH21100 is rated for 12 A UL, and OQ2112510000G is rated for 10 A UL. Both substitute ratings remain within acceptable operational margins for terminal block header applications in this category.

Q: How do the operating temperature ranges differ?

A: The original 2-284539-1 operates from -40°C to 110°C. ELXH21100 extends the upper limit to 125°C, providing enhanced thermal performance. OQ2112510000G operates from -40°C to 115°C. Selection depends on specific application thermal requirements.

Q: What packaging formats are available for the substitute parts?

A: ELXH21100 is supplied in tray packaging. OQ2112510000G is supplied in bulk packaging. Packaging selection should align with production workflow and inventory management requirements.

Q: Are the substitute parts RoHS compliant?

A: ELXH21100 carries RoHS compliance certification. OQ2112510000G carries ROHS3 compliance certification. The original 2-284539-1 has RoHS status listed as not applicable. Both substitutes support modern regulatory compliance requirements.

Q: What contact materials are used in each part?

A: The original 2-284539-1 uses Phosphor Bronze contacts. ELXH21100 uses Brass contacts. OQ2112510000G uses Copper Alloy contacts. All three materials provide adequate electrical conductivity and corrosion resistance for terminal block applications with tin mating finish.

Q: Do the substitute parts maintain the same shrouding configuration?

A: Yes. All three parts feature four-side shrouding with male pin headers, maintaining identical mechanical protection and mating interface characteristics.
