Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1722231 qualifies as a direct substitute for the 1909100 based on the following critical parameters:

• Electrical Compatibility: Both parts maintain identical current ratings (8A IEC/UL) and voltage ratings (250V IEC, 300V UL)
• Mechanical Compatibility: Both feature 9 positions, 0.150" (3.81mm) pitch, 90° right-angle orientation, and through-hole solder termination
• Connector Type: Both are male pin headers with four-side shrouding
• Regulatory Compliance: Both are RoHS compliant with UL94 V-0 flammability rating and MSL 1 classification
• Series Alignment: Both belong to the COMBICON MC series

The primary distinction lies in housing material composition and dimensional tolerances of internal contact geometry, which do not affect electrical or mechanical interface compatibility.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1722231 is the appropriate selection for applications currently using or specifying the 1909100. The substitute part maintains full electrical and mechanical compatibility while offering the advantage of active product status, ensuring long-term availability and supply chain continuity.

The housing material change from glass-filled polyamide to liquid crystal polymer (LCP) in the 1722231 provides enhanced thermal and chemical resistance properties. The minor dimensional variations in contact tail length (0.134" to 0.102") and insulation height (0.285" to 0.272") remain within acceptable tolerances for standard through-hole PCB applications and do not compromise interface compatibility.

Both parts satisfy identical regulatory requirements, including RoHS compliance, UL94 V-0 flammability classification, and MSL 1 moisture sensitivity rating, making them suitable for equivalent deployment in industrial control, telecommunications, and instrumentation applications.

Frequently Asked Questions (FAQ)

Q: Can the 1722231 directly replace the 1909100 in existing designs?

A: Yes. Both parts share identical electrical ratings (8A/250V IEC, 8A/300V UL), mechanical configuration (9 positions, 3.81mm pitch, 90° right angle), and connector interface specifications. The parts are mechanically and electrically interchangeable.

Q: What is the significance of the housing material difference?

A: The 1909100 uses glass-filled polyamide while the 1722231 uses liquid crystal polymer. Both materials meet UL94 V-0 flammability requirements. LCP offers superior thermal stability and chemical resistance, making it suitable for demanding environmental conditions.

Q: Are there dimensional concerns with the contact tail length difference?

A: The contact tail length reduction from 0.134" (3.40mm) to 0.102" (2.60mm) is a minor dimensional change that does not affect PCB through-hole compatibility or solder joint integrity in standard applications. Both dimensions are within acceptable manufacturing tolerances for this connector class.

Q: Why is the 1909100 listed as obsolete?

A: Product obsolescence reflects Phoenix Contact's lifecycle management. The 1722231 represents the current active equivalent, ensuring continued availability and manufacturing support for this connector configuration.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1909100 and 1722231 are RoHS compliant with identical MSL 1 (Unlimited) moisture sensitivity ratings, suitable for standard storage and handling conditions.

Q: What packaging options are available?

A: The 1909100 is available in standard packaging, while the 1722231 is supplied in bulk packaging. Both formats accommodate production and inventory requirements for through-hole assembly operations.
