ELFH22280 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH22280 is a 22-position terminal block header manufactured by Amphenol PCD, designed for vertical through-hole mounting with 5.08mm pitch spacing. This shrouded, male-pin header operates at 300V UL and 15A UL current rating, suitable for industrial control and power distribution applications. The component is actively produced and RoHS compliant, making it suitable for modern electronic assemblies requiring reliable interconnection solutions.

Substitute parts become necessary when the primary manufacturer experiences supply constraints, when alternative sourcing reduces procurement costs, or when design flexibility permits equivalent components from qualified manufacturers. The parts listed below maintain functional compatibility through matching electrical ratings, mechanical dimensions, and termination methods.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELFH22280 is determined by the following critical parameters:

Primary Matching Criteria:

• 22 positions per level
• Vertical orientation
• Male pins with 4-side shrouding
• Through-hole solder termination
• UL94 V-0 flammability rating
• RoHS compliance status

Electrical Compatibility Criteria:

• Voltage rating minimum 300V UL
• Current rating minimum 12A UL (acceptable reduction from 15A UL for most applications)
• Contact mating finish: Tin

Mechanical Compatibility Criteria:

• Pitch tolerance: 5.08mm ±0.05mm (includes 5.00mm variants within acceptable tolerance)
• Contact tail length: 0.154" to 0.155" (3.90mm to 3.94mm)
• Insulation height: 0.472" to 0.475" (12.00mm to 12.07mm)

The substitute parts listed below satisfy these criteria and are therefore electrically and mechanically interchangeable with the ELFH22280 in standard PCB assembly applications.

Parameter Comparison

Engineering Selection Recommendations

1755930 (Phoenix Contact COMBICON MSTBVA Series)

This part provides the closest electrical and mechanical match to the ELFH22280. It maintains identical 5.08mm pitch spacing, 300V UL voltage rating, and UL94 V-0 flammability compliance. The 12A UL current rating is lower than the primary part but remains suitable for applications not requiring the full 15A capacity. ROHS3 compliance exceeds the RoHS requirement. This substitute is recommended as the primary alternative when ELFH22280 availability is constrained.

1755707 (Phoenix Contact COMBICON MSTBVA Series)

This part operates at 5.00mm pitch, representing a 0.08mm deviation from the ELFH22280 specification. While this pitch variance falls within typical PCB layout tolerances for standard through-hole applications, it requires verification that existing PCB footprints accommodate the dimensional difference. The 12A UL current rating and 300V UL voltage rating match the electrical requirements. ROHS3 compliance and UL94 V-0 flammability rating are equivalent. This substitute is suitable only when PCB design permits the pitch tolerance variation.

Both substitute parts are actively produced by Phoenix Contact, a qualified manufacturer with established quality certifications. Selection between these options depends on PCB layout constraints and current capacity requirements of the specific application.

Frequently Asked Questions (FAQ)

Q: Can I use 1755930 as a direct replacement for ELFH22280?

A: Yes. The 1755930 maintains identical 5.08mm pitch, matching mechanical footprint and electrical ratings (300V UL). The 12A UL current rating is lower than the ELFH22280's 15A UL rating; verify that your application current requirements do not exceed 12A. Both parts are UL94 V-0 compliant and RoHS certified.

Q: What is the pitch difference between ELFH22280 and 1755707?

A: The ELFH22280 operates at 0.200" (5.08mm) pitch, while the 1755707 operates at 0.197" (5.00mm) pitch. This represents a 0.08mm difference. Standard PCB design tolerances typically accommodate this variance, but existing PCB layouts designed for 5.08mm spacing must be verified before substitution.

Q: Are the electrical ratings compatible between all three parts?

A: All three parts are rated for 300V UL. The ELFH22280 and 1755930 are rated for 12A UL minimum; the ELFH22280 provides 15A UL capacity. Verify that your application current requirements do not exceed 12A when using Phoenix Contact substitutes.

Q: Do all parts meet RoHS compliance requirements?

A: Yes. The ELFH22280 is RoHS Compliant. Both Phoenix Contact substitutes (1755930 and 1755707) are ROHS3 Compliant, which exceeds the RoHS requirement and indicates compliance with the latest RoHS directive revisions.

Q: What is the packaging difference between these parts?

A: The ELFH22280 is supplied in Tray packaging. Both Phoenix Contact substitutes (1755930 and 1755707) are supplied in Bulk packaging. Verify that bulk packaging meets your procurement and storage requirements.

Q: Can I mix ELFH22280 and 1755707 in the same assembly?

A: No. Mixing components with different pitch specifications (5.08mm vs. 5.00mm) in the same PCB assembly is not recommended. PCB footprints are designed for a single pitch specification. Use one part number consistently throughout an assembly.

Q: What is the operating temperature range for these parts?

A: The ELFH22280 operates from -40°C to 105°C. Operating temperature data for the Phoenix Contact substitutes (1755930 and 1755707) is not provided in the available specifications. Consult Phoenix Contact technical documentation for complete thermal operating range information.
