ELVA20100 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELVA20100 is a 20-position terminal block header manufactured by Amphenol PCD, designed for through-hole solder mounting applications. This shrouded, right-angle header features male pins with 0.150" (3.81mm) pitch spacing and is rated for 12 A at 300 V (UL). The component is actively produced and stocked, with 918 units available in inventory. Equivalent parts are identified when they maintain functional compatibility across critical electrical and mechanical parameters while meeting the same application requirements.

Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1843156 qualifies as a functional equivalent to the ELVA20100 based on the following critical parameters:

• Position Configuration: Both parts feature 20 positions arranged in 2 levels with 10 positions per level
• Pitch Spacing: Both maintain 0.150" (3.81mm) pitch, ensuring mechanical compatibility with mating connectors
• Header Type: Both are shrouded (4-side), right-angle male pin headers
• Termination: Both use solder termination for through-hole mounting
• Contact Tail Length: Both specify 0.138" (4.60mm) contact tail length
• Insulation Height: Both maintain comparable insulation heights (0.890" vs 0.894")
• Flammability Rating: Both meet UL94 V-0 material flammability requirements
• Compliance: Both are RoHS compliant

The 1843156 operates at reduced current ratings (8 A IEC/UL vs 12 A UL) and includes IEC voltage specification (320 V IEC) alongside UL ratings. Both components are actively produced and available in stock.

Parameter Comparison

Engineering Selection Recommendations

Both the ELVA20100 and 1843156 are actively produced components with current availability. Selection between these parts depends on application current requirements:

The ELVA20100 supports 12 A at 300 V (UL) and is suitable for applications requiring the full current rating. The 1843156 operates at 8 A (UL) and 8 A (IEC) with 320 V (IEC) and 300 V (UL) ratings, making it appropriate for applications with lower current demands. Both components meet UL94 V-0 flammability requirements and maintain RoHS compliance. The mechanical compatibility across pitch, contact tail length, and insulation height ensures interchangeability in PCB layouts designed for 0.150" (3.81mm) pitch terminal block headers.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1843156 replace the Amphenol PCD ELVA20100 in all applications?

A: The 1843156 is mechanically and electrically compatible for applications operating at 8 A or below. Applications requiring the full 12 A rating of the ELVA20100 must use the original part or verify that the substitute's 8 A rating meets the circuit requirements.

Q: Are the pitch and contact spacing identical between these parts?

A: Yes. Both parts maintain 0.150" (3.81mm) pitch spacing and 0.138" (4.60mm) contact tail length, ensuring compatibility with mating connectors and PCB footprints designed for either component.

Q: What is the difference in insulation height between these parts?

A: The ELVA20100 specifies 0.890" (22.61mm) insulation height, while the 1843156 specifies 0.894" (22.71mm). This 0.004" (0.10mm) difference is negligible for standard PCB applications and does not affect functional compatibility.

Q: Do both parts meet the same compliance standards?

A: Both parts meet UL94 V-0 flammability requirements and are RoHS compliant. The 1843156 carries ROHS3 compliance designation, while the ELVA20100 is RoHS Compliant. Both are suitable for applications requiring RoHS compliance.

Q: What packaging differences exist between these parts?

A: The ELVA20100 is supplied in Tray packaging, while the 1843156 is supplied in Bulk packaging. Packaging format does not affect component functionality or electrical performance.
