Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1981678 is based on strict equivalence across the following critical parameters:

• Electrical Compatibility: Identical current and voltage ratings (12A at 630V IEC; 10A at 300V UL)
• Mechanical Compatibility: Matching number of positions (10), pitch (5.00mm), and wire entry angle (180°)
• Termination Method: Identical screwless push-in spring termination style
• Mounting Configuration: Free-hanging in-line orientation
• Wire Gauge Acceptance: Identical range (12-26 AWG / 0.2-2.5mm²)
• Material and Safety Compliance: Polyamide housing with UL94 V-0 flammability rating and RoHS compliance

The substitute part 1910908 meets all these criteria and represents the active equivalent within the Phoenix Contact COMBICON product family.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1910908 is the direct active equivalent for the obsolete 1981678. Both components maintain identical electrical ratings, mechanical dimensions, and termination characteristics. The 1910908 is currently in active production status with confirmed inventory availability (851 pcs), ensuring supply chain continuity.

Both parts carry RoHS compliance and UL94 V-0 flammability certification, meeting regulatory requirements for industrial terminal block applications. The transition from the COMBICON FKICS series (1981678) to the COMBICON FKIC series (1910908) represents a product line evolution within Phoenix Contact's connector portfolio, with no functional or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1910908 directly replace 1981678 in existing applications?

A: Yes. The 1910908 is electrically and mechanically equivalent to the 1981678 across all critical parameters: 10-position configuration, 5mm pitch, 12A/630V IEC rating, 10A/300V UL rating, identical termination method, and free-hanging in-line mounting. No circuit modifications are required.

Q: What is the primary difference between these two parts?

A: The 1981678 is obsolete, while the 1910908 is an active product. Both belong to the Phoenix Contact COMBICON family but represent different series designations (FKICS vs. FKIC). Functionally, they are equivalent.

Q: Are there packaging differences between 1981678 and 1910908?

A: The 1981678 was supplied in standard packaging, while the 1910908 is available in bulk packaging. This does not affect component performance or compatibility.

Q: What wire gauges are compatible with the 1910908?

A: The 1910908 accepts wire gauges from 12 to 26 AWG, equivalent to 0.2 to 2.5mm². This range matches the original 1981678 specification.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1981678 and 1910908 are RoHS compliant and carry UL94 V-0 flammability certification, meeting current regulatory standards for industrial applications.

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

A: Both parts have an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
