Key Parameters

Substitute Part Grouping Explanation

Substitution of terminal block plugs is determined by strict electrical and mechanical compatibility. The following parameters establish whether a substitute part is functionally equivalent to the Phoenix Contact 1939578:

Critical Substitution Parameters:

• Number of positions (7)
• Pitch spacing (0.295" / 7.50mm)
• Plug wire entry orientation (180°)
• Termination style (Screwless - Push-In Spring)
• Mounting type (Free Hanging / In-Line)
• Current and voltage ratings (IEC: 12A / 1 kV; UL: 10A / 300V)
• Wire gauge compatibility (12-26 AWG / 0.2-2.5mm²)
• Housing material and flammability rating (Polyamide PA, UL94 V-0)
• Contact mating finish (Tin)

The Phoenix Contact 1939468 meets all critical substitution parameters and is classified as a direct equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1939468 is a direct functional equivalent to the obsolete 1939578. Both components are manufactured by Phoenix Contact within the COMBICON GFKC series and share identical electrical ratings, mechanical dimensions, and termination characteristics.

The 1939468 is currently in active production status, whereas the 1939578 is obsolete. For new designs or component replacement in existing systems, the 1939468 is the appropriate selection. Both parts maintain RoHS compliance and UL94 V-0 flammability certification, ensuring regulatory conformance in applications requiring these standards.

The primary distinction between the two parts is packaging: the 1939578 was supplied in standard packaging, while the 1939468 is available in bulk packaging. This difference does not affect electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1939468 directly replace the 1939578 in existing installations?

A: Yes. The 1939468 is electrically and mechanically identical to the 1939578. All critical parameters—position count, pitch, wire entry angle, termination method, current/voltage ratings, and wire gauge compatibility—are identical. Direct substitution is appropriate.

Q: What is the difference between the 1939578 and 1939468?

A: The primary difference is product status and packaging. The 1939578 is obsolete; the 1939468 is active production. The 1939468 is supplied in bulk packaging, while the 1939578 was supplied in standard packaging. Electrical and mechanical specifications are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1939578 and 1939468 are RoHS compliant and carry UL94 V-0 flammability certification.

Q: What wire gauges are compatible with these terminal block plugs?

A: Both parts accept wire gauges from 12-26 AWG (0.2-2.5mm²).

Q: What is the current and voltage rating for these components?

A: IEC ratings are 12A at 1 kV. UL ratings are 10A at 300V. Applications must operate within the lower of these two rating sets.

Q: Is the 1939468 available in the same packaging as the 1939578?

A: The 1939468 is supplied in bulk packaging. If standard packaging is required, contact the manufacturer or authorized distributor for packaging options.
