Engineering Selection Recommendations

The N111X is the direct active equivalent for the obsolete N111. All electrical and mechanical parameters are identical, ensuring drop-in compatibility in existing designs and applications. The primary distinction is product status: the N111 is obsolete while the N111X is active and currently in production.

The N111X offers improved regulatory compliance, meeting ROHS3 standards compared to the N111's non-compliant status. This compliance improvement is significant for applications subject to environmental and regulatory requirements. Both parts share identical electrical ratings (48VDC, 250 mA), mechanical specifications (panel hole size, thread size), and material composition (brass contacts with tin plating, polyester glass-filled housing).

For new designs or replacement applications requiring the 6.35mm mono headphone jack connector with panel mount through-hole configuration, the N111X is the appropriate selection. Inventory availability of the N111X (5501 pcs) supports production requirements.

Frequently Asked Questions (FAQ)

Q: Can the N111X directly replace the N111 in existing assemblies?

A: Yes. The N111X is a direct substitute with identical electrical and mechanical parameters. Panel hole size (0.375"), thread size (3/8"-32), contact configuration (2 conductors, 2 contacts), and all electrical ratings (48VDC, 250 mA) are identical. Physical installation and electrical performance are equivalent.

Q: What is the difference between the N111 and N111X?

A: The N111 is obsolete; the N111X is active. The N111X meets ROHS3 compliance standards while the N111 does not. All functional and mechanical specifications are identical. The N111X is available in bulk packaging.

Q: Are there packaging differences between the N111 and N111X?

A: The N111X is supplied in bulk packaging, while the N111 packaging specification is not defined. Both include the same connector assembly: 1 connector, 1 nut, and 1 washer per unit.

Q: What applications use the 6.35mm mono phone jack connector?

A: The N111/N111X is designed for audio equipment, professional audio interfaces, and consumer electronics requiring 6.35mm (1/4") headphone jack connectivity with panel-mounted through-hole installation.

Q: Are the contact materials identical between N111 and N111X?

A: Yes. Both use brass contacts with tin plating, ensuring equivalent electrical performance and corrosion resistance.

Q: What is the operating temperature range for both parts?

A: Both the N111 and N111X operate across -20°C to 65°C, supporting standard industrial and consumer applications.
