Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1981908 is based on strict equivalence across the following critical parameters:

• Electrical Specifications: Current rating (12A IEC / 10A UL) and voltage rating (630V IEC / 300V UL) must match exactly
• Physical Configuration: 3-position count, 0.200" (5.08mm) pitch, and 180° wire entry orientation are non-negotiable
• Termination Method: Screwless push-in spring termination must be maintained
• Wire Compatibility: Support for 12-26 AWG (0.2-2.5mm²) wire gauge range
• Material & Compliance: Polyamide housing with UL94 V-0 flammability rating and RoHS compliance

The substitute part 1873511 meets all these criteria while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1873511 is a direct functional equivalent to the obsolete 1981908. Both components share identical electrical ratings, physical dimensions, termination characteristics, and compliance certifications. The primary distinction is product lifecycle status: 1981908 is obsolete while 1873511 maintains active production status with confirmed inventory availability (1014 pcs in stock versus 874 pcs for the obsolete part).

For new designs and ongoing procurement, 1873511 is the appropriate selection. For legacy system maintenance where original part numbers must be preserved, 1873511 provides full electrical and mechanical compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can 1873511 be used as a direct replacement for 1981908 in existing assemblies?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. No circuit modifications or mechanical redesign is required.

Q: What is the difference between the COMBICON FKICS and COMBICON FKIC series designations?

A: Series designation reflects product line evolution. Both series maintain identical electrical and mechanical specifications for this 3-position, 5.08mm pitch configuration.

Q: Are there packaging differences between these parts?

A: The 1981908 packaging specification is not provided. The 1873511 is supplied in bulk packaging. Confirm packaging requirements for your application.

Q: Do both parts support the same wire gauge range?

A: Yes. Both components accept 12-26 AWG (0.2-2.5mm²) wire gauges with identical push-in spring termination.

Q: Are compliance certifications identical?

A: Yes. Both parts carry UL94 V-0 flammability rating, RoHS compliance, MSL 1 rating, and identical ECCN and HTSUS classifications.

Q: Why is 1981908 listed as obsolete?

A: Product status reflects Phoenix Contact's lifecycle management. The 1873511 represents the current active equivalent within the COMBICON terminal block family.
