Key Parameters

Substitute Part Grouping Explanation

The J0C-0004NL qualifies as a direct substitute based on identical electrical and mechanical parameters. Substitution eligibility is determined by the following criteria:

• Connector type and port configuration (RJ45, 1 port)
• Mounting method and board orientation (Surface Mount, 90° right angle)
• Physical dimensions and height above board (0.545" / 13.84mm)
• Electrical performance specifications (10/100 Base-TX, AutoMDIX, 4 cores)
• Contact material and finish properties (Phosphor Bronze, Gold plating)
• Shielding configuration (Shielded with EMI finger)
• Operating temperature range (0°C ~ 70°C)

The J0C-0004NL maintains full compatibility across all functional and mechanical parameters while offering improved product status and compliance characteristics.

Engineering Selection Recommendations

The J0C-0004NL is the appropriate selection for new designs and production continuity. The original J0C-0004 is obsolete and presents supply chain risk. The substitute part J0C-0004NL offers the following advantages:

• Active product status ensures ongoing availability and manufacturer support
• RoHS compliance aligns with current regulatory requirements and industry standards
• Improved moisture sensitivity level (MSL 1 vs. MSL 4) reduces handling and storage constraints
• Identical electrical and mechanical specifications ensure direct form-fit-function compatibility
• Maintains all shielding and EMI performance characteristics
• Preserves operating temperature range and contact material specifications

Frequently Asked Questions (FAQ)

Q: Can J0C-0004NL be used as a direct replacement for J0C-0004 in existing designs?

A: Yes. The J0C-0004NL maintains identical connector type, port configuration, mounting method, orientation, height, termination, shielding, contact materials, and electrical performance specifications. No design modifications are required.

Q: What is the significance of the RoHS compliance difference?

A: The J0C-0004NL is RoHS compliant, meeting Restriction of Hazardous Substances regulations. The original J0C-0004 is non-compliant. For applications subject to RoHS requirements or future regulatory compliance, the J0C-0004NL is the appropriate choice.

Q: How does the Moisture Sensitivity Level (MSL) difference affect component handling?

A: The J0C-0004 has MSL 4 (72-hour limit), requiring controlled storage and shorter exposure windows. The J0C-0004NL has MSL 1 (unlimited), eliminating moisture sensitivity constraints and simplifying inventory management and assembly processes.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts support 10/100 Base-TX with AutoMDIX, feature identical contact materials (Phosphor Bronze with Gold finish), shielding configuration (EMI finger), and operating temperature range (0°C ~ 70°C).

Q: What is the inventory status for each part?

A: J0C-0004 has 1106 pieces in stock (obsolete status). J0C-0004NL has 720 pieces in stock (active status). For new production, J0C-0004NL availability is recommended.
