ELFH22260 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH22260 is a 22-position terminal block header manufactured by Amphenol PCD, designed for vertical through-hole mounting with 0.200" (5.08mm) pitch spacing. This component features male pins with 2-side shrouding and is rated for 15 A at 300 V (UL). The part is currently active in production with 951 units in stock. Alternative equivalent parts may be required due to supply constraints, packaging preferences, or specific application requirements for different shrouding configurations or voltage ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ELFH22260 is determined by the following critical parameters that must remain consistent:

• Number of Positions: 22 positions (fixed requirement)
• Pitch: 0.200" (5.08mm) (fixed requirement)
• Header Orientation: Vertical (fixed requirement)
• Termination Style: Solder (fixed requirement)
• Mounting Type: Through Hole (fixed requirement)
• Contact Tail Length: Approximately 0.155" (3.94mm) ±0.001"
• Insulation Height: Approximately 0.475" (12.07mm) ±0.003"

The Phoenix Contact 1755930 qualifies as an equivalent substitute because it maintains all critical dimensional and functional parameters. The primary difference is the shrouding configuration (4-side versus 2-side), which does not affect electrical compatibility or mechanical fit in standard applications. The substitute also maintains UL94 V-0 flammability rating and operates within the same voltage specification (300 V UL).

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1755930 is an acceptable equivalent substitute for the ELFH22260 based on the following engineering criteria:

Electrical Compatibility: Both parts maintain 300 V UL voltage rating and UL94 V-0 flammability classification. The substitute's 12 A UL current rating is lower than the original 15 A rating; applications requiring the full 15 A capacity must use the ELFH22260.

Mechanical Compatibility: Contact tail length and insulation height differences are within acceptable manufacturing tolerances (0.001" and 0.003" respectively). Both parts are through-hole solder-mount with identical 22-position, 5.08mm pitch configuration.

Regulatory Compliance: Both parts are RoHS compliant (ELFH22260 is RoHS Compliant; 1755930 is ROHS3 Compliant). Both maintain active product status with established supply chains.

Shrouding Difference: The 4-side shrouding of the 1755930 provides enhanced EMI shielding and mechanical protection compared to the 2-side shrouding of the ELFH22260. This difference does not prevent substitution in standard applications but may affect board layout or connector mating characteristics.

Packaging Consideration: The ELFH22260 is supplied in trays; the 1755930 is supplied in bulk. Procurement and handling procedures may differ accordingly.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1755930 be used as a direct replacement for the ELFH22260?

A: Yes, for applications requiring up to 12 A at 300 V. The 1755930 maintains identical position count, pitch, orientation, and termination style. Applications requiring the full 15 A capacity must use the ELFH22260.

Q: What is the significance of the shrouding difference (2-side vs. 4-side)?

A: The 2-side shrouding on the ELFH22260 provides lateral protection, while the 4-side shrouding on the 1755930 provides complete perimeter protection. The 4-side configuration offers improved EMI shielding and mechanical robustness. Both configurations are mechanically compatible with standard mating connectors at 5.08mm pitch.

Q: Are the dimensional differences between the two parts significant?

A: No. The contact tail length difference (0.155" vs. 0.154") and insulation height difference (0.475" vs. 0.472") are within standard manufacturing tolerances and do not affect PCB mounting or connector mating.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: Both designations indicate compliance with RoHS (Restriction of Hazardous Substances) regulations. ROHS3 refers to the third iteration of the directive with updated substance restrictions. Both parts meet current RoHS requirements.

Q: Does the different packaging (Tray vs. Bulk) affect electrical performance?

A: No. Packaging format affects only logistics, handling, and storage procedures. Electrical and mechanical performance is identical regardless of packaging type.

Q: Can I use the 1755930 in a high-current application requiring 15 A?

A: No. The 1755930 is rated for 12 A maximum at UL specifications. For 15 A applications, the ELFH22260 must be used.

Q: Are both parts suitable for the operating temperature range of -40°C to 105°C?

A: The ELFH22260 is specified for -40°C to 105°C. The 1755930 operating temperature range is not provided in the available specifications. Verify the 1755930 operating temperature requirements with the manufacturer for applications requiring full temperature range coverage.
