Key Parameters

Substitute Part Grouping Explanation

The J00-0045NL qualifies as a direct substitute based on the following critical parameters:

• Connector Type: Both are RJ45 modular connectors
• Port Configuration: Both feature 1 port with 1 row
• Mounting and Orientation: Both use Through Hole mounting with 90° right angle orientation
• Electrical Specifications: Both support 10/100 Base-TX and AutoMDIX applications
• Physical Dimensions: Both share identical height above board (0.545" / 13.84mm)
• Contact Properties: Both use Phosphor Bronze contacts with Gold finish
• Shielding: Both are shielded connectors with Board Guide feature
• Termination Method: Both use solder termination
• Operating Temperature Range: Both operate within 0°C ~ 70°C

The primary distinction between these parts is product status and compliance certification, not functional or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The J00-0045NL is the appropriate substitute for the obsolete J00-0045. Both components are electrically and mechanically equivalent across all functional parameters. The J00-0045NL offers the following advantages:

• Active product status ensures long-term availability and manufacturer support
• RoHS Compliant certification meets current environmental and regulatory requirements
• Significantly higher inventory availability (326,647 units vs. 1,083 units) supports production continuity
• Tube packaging provides improved handling and traceability compared to bulk packaging

For applications requiring RoHS non-compliant components, the J00-0045 remains available in limited stock. For new designs or ongoing production requiring regulatory compliance, the J00-0045NL is the specified alternative.

Frequently Asked Questions (FAQ)

Q: Are J00-0045 and J00-0045NL mechanically interchangeable?

A: Yes. Both connectors share identical mounting type (Through Hole), orientation (90° right angle), and height above board (0.545" / 13.84mm). PCB layout and mechanical assembly are identical.

Q: Are these connectors electrically equivalent?

A: Yes. Both support 10/100 Base-TX and AutoMDIX applications with identical contact materials (Phosphor Bronze), contact finish (Gold), and shielding specifications.

Q: What is the primary difference between these parts?

A: The J00-0045 is obsolete with RoHS non-compliant status, while the J00-0045NL is an active product with RoHS Compliant certification. Functionally and mechanically, they are equivalent.

Q: Can I use J00-0045NL in place of J00-0045 in existing designs?

A: Yes. The J00-0045NL is a direct substitute with no design modifications required. Verify that your application requirements align with RoHS Compliant status.

Q: What packaging formats are available?

A: J00-0045 is supplied in bulk packaging. J00-0045NL is supplied in tube packaging, which provides improved component protection and traceability.

Q: Are there any temperature or environmental differences?

A: No. Both connectors operate within the same temperature range (0°C ~ 70°C) and share identical moisture sensitivity level (MSL 1 - Unlimited).
