Substitute Part Grouping Explanation

The Phoenix Contact 1722176 qualifies as a direct substitute for the 1908897 based on the following critical parameters:

Electrical Compatibility: Both parts maintain identical current (8A IEC/UL) and voltage ratings (250V IEC, 300V UL)
Mechanical Compatibility: Matching pitch (0.150"/3.81mm), position count (4), orientation (90° right angle), and termination method (solder through-hole)
Connector Type: Both are male pin headers with 4-side shrouded design
Series Alignment: Both belong to the COMBICON MC series
Regulatory Compliance: Both meet UL94 V-0 flammability requirements and RoHS standards

The primary distinction is product status: 1908897 is obsolete, while 1722176 is active production. Housing material differs (Polyamide vs. Liquid Crystal Polymer), and dimensional variations exist in contact tail length and insulation height, but these do not affect functional substitution within the specified electrical and mechanical parameters.

Engineering Selection Recommendations

The Phoenix Contact 1722176 is the direct active equivalent for the obsolete 1908897. Selection should be based on the following factors:

Product Status: The 1908897 is obsolete and no longer in active production. The 1722176 is an active production part within the same COMBICON MC series, ensuring long-term availability and supply chain continuity.

Regulatory Compliance: Both parts meet UL94 V-0 flammability standards and RoHS requirements. The 1722176 carries ROHS3 compliance, representing current regulatory alignment. Both are classified as EAR99 for export control purposes.

Electrical Performance: Identical current and voltage ratings across both IEC and UL standards ensure functional equivalence in circuit applications. No derating or performance adjustment is required.

Physical Integration: While housing material differs (glass-filled polyamide versus liquid crystal polymer) and dimensional variations exist in contact tail length and insulation height, these changes do not affect electrical performance or standard PCB mounting compatibility within the specified mechanical envelope.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1722176 be used as a direct replacement for 1908897 in existing designs?

A: Yes. Both parts share identical electrical ratings (8A/250V IEC, 8A/300V UL), pitch spacing (3.81mm), position count (4), orientation (90° right angle), and termination method (solder through-hole). The 1722176 is the active production equivalent.

Q: What is the difference in housing material between these parts?

A: The 1908897 uses glass-filled polyamide (PA/nylon), while the 1722176 uses liquid crystal polymer (LCP). Both materials meet UL94 V-0 flammability requirements. LCP offers improved dimensional stability and thermal performance.

Q: Are there dimensional differences that affect PCB layout?

A: Yes. The contact tail length differs (0.134" vs. 0.102") and insulation height differs (0.285" vs. 0.272"). These variations are within standard manufacturing tolerances for the COMBICON MC series and do not affect standard through-hole PCB mounting. Verify pad spacing and clearances for your specific PCB design.

Q: Is the 1722176 available in the same packaging as the 1908897?

A: The 1908897 packaging is listed as unspecified. The 1722176 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Do both parts meet current environmental and regulatory standards?

A: Both parts are RoHS compliant. The 1722176 carries ROHS3 compliance, representing alignment with current regulatory requirements. Both are classified as EAR99 for export control.

Q: What is the moisture sensitivity level for these parts?

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
