Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the NL112A must maintain electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility:

• Connector type: Phone Jack (Female)
• Signal configuration: Mono
• Mating diameter: 6.35mm (0.250", 1/4")
• Contact count: 2 Conductors, 3 Contacts
• Voltage rating: 48VDC minimum
• Current rating: 250 mA minimum

Mechanical Compatibility:

• Mounting type: Panel Mount, Through Hole
• Termination: Solder Eyelet(s)
• Panel hole size: 0.375" (9.52mm)
• Thread size: 3/8"-32
• Operating temperature range: -20°C ~ 65°C minimum

Regulatory Compliance:

• RoHS3 Compliant status

Parts meeting all these criteria are classified as direct substitutes and can be used interchangeably in the same application without circuit or mechanical redesign.

Parameter Comparison

Engineering Selection Recommendations

The NL112AX is a direct substitute for the NL112A. Both parts are manufactured by Switchcraft Inc., belong to the Hi-D® NL11 series, and share identical electrical and mechanical specifications. Both parts maintain active product status and are ROHS3 compliant, meeting current regulatory requirements.

Selection between NL112A and NL112AX should be based on availability and procurement lead times. The NL112AX currently has higher inventory availability (1171 units versus 753 units), which may provide supply chain advantages for high-volume applications or extended production runs.

No electrical redesign, mechanical modification, or performance trade-offs are required when substituting between these parts. Both connectors are suitable for identical applications requiring 6.35mm mono headphone jack functionality with panel mount solder eyelet termination.

Frequently Asked Questions (FAQ)

Q: Can the NL112AX be used as a direct replacement for the NL112A in existing designs?

A: Yes. The NL112AX is a direct substitute with identical electrical ratings, mechanical dimensions, mounting specifications, and termination method. No circuit or mechanical redesign is required.

Q: Are there any differences in contact material or plating between these parts?

A: No. Both the NL112A and NL112AX use tin-plated brass contacts, ensuring equivalent electrical performance and reliability.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both the NL112A and NL112AX are ROHS3 compliant and meet current environmental and safety requirements.

Q: What is the panel hole size requirement for installation?

A: Both connectors require a 0.375" (9.52mm) panel hole with 3/8"-32 threading for secure panel mount installation.

Q: Are there any temperature or voltage limitations when substituting between these parts?

A: No. Both parts operate across the same temperature range (-20°C ~ 65°C) and are rated for 48VDC at 250 mA, ensuring equivalent performance in all specified operating conditions.

Q: What accessories are included with each connector?

A: Both parts include mounting hardware: 1 connector, 1 nut, and 1 washer per unit.
