Substitute Part Grouping Explanation

The Phoenix Contact 1755930 qualifies as an equivalent substitute based on the following critical parameters:

Matching Parameters:

Number of positions: 22
Pitch spacing: 0.200" (5.08mm)
Header orientation: Vertical
Termination style: Solder
Mounting type: Through Hole
Contact mating finish: Tin
Material flammability rating: UL94 V-0
Voltage rating (UL): 300 V
Product status: Active

Differing Parameters:

Shrouding configuration: 2-side (ELFH22290) vs. 4-side (1755930)
Current rating (UL): 15 A (ELFH22290) vs. 12 A (1755930)
Current rating (IEC): Not specified (ELFH22290) vs. 12 A (1755930)
Voltage rating (IEC): Not specified (ELFH22290) vs. 630 V (1755930)
Housing color: Black (ELFH22290) vs. Green (1755930)
Packaging: Tray (ELFH22290) vs. Bulk (1755930)

The 1755930 provides enhanced shrouding (4-side vs. 2-side) and higher IEC voltage rating, making it suitable for applications requiring greater mechanical protection or compliance with IEC standards.

Engineering Selection Recommendations

Both the ELFH22290 and 1755930 are active production components with equivalent electrical performance at UL ratings (300 V, with ELFH22290 rated at 15 A and 1755930 at 12 A). Both meet UL94 V-0 flammability requirements and carry MSL 1 moisture sensitivity ratings.

The ELFH22290 is suitable for applications requiring the specified 15 A UL current rating with 2-side shrouding. The 1755930 provides 4-side shrouding and IEC compliance (12 A at 630 V IEC), making it appropriate for applications requiring enhanced mechanical protection or IEC standard compliance. The contact tail length and insulation height are dimensionally equivalent within manufacturing tolerances.

Selection between these parts should be based on application-specific requirements for shrouding configuration, current rating, and regulatory compliance standards (UL vs. IEC).

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1755930 directly replace the ELFH22290 in all applications?

A: The 1755930 is electrically compatible at UL ratings (300 V) but has a lower UL current rating (12 A vs. 15 A). Applications requiring the full 15 A UL rating must use the ELFH22290. The 4-side shrouding of the 1755930 provides additional mechanical protection compared to the 2-side shrouding of the ELFH22290.

Q: What is the significance of the shrouding difference between 2-side and 4-side?

A: 2-side shrouding provides protection on two opposing sides of the connector, while 4-side shrouding provides protection on all four sides. The 4-side configuration offers greater mechanical protection and may be required for applications with higher vibration or environmental exposure.

Q: Are there differences in compliance certifications between these parts?

A: Both parts are RoHS compliant and carry UL94 V-0 flammability ratings. The 1755930 additionally specifies ROHS3 compliance and REACH unaffected status. Both are classified as EAR99 for export control purposes.

Q: How do the contact tail lengths and insulation heights compare?

A: The contact tail lengths are nearly identical (0.155" vs. 0.154") and insulation heights are equivalent within manufacturing tolerances (0.475" vs. 0.472"), ensuring compatibility with standard PCB footprints and through-hole mounting requirements.

Q: What packaging differences exist between these parts?

A: The ELFH22290 is supplied in tray packaging, while the 1755930 is supplied in bulk packaging. Packaging selection may affect inventory management and handling procedures but does not impact electrical or mechanical performance.
