Key Parameters

Substitute Part Grouping Explanation

The 90512-003LF qualifies as a direct substitute for the 90512-003 based on the following critical parameters:

• Identical connector type, position count, and contact configuration (6p4c RJ11/RJ14)
• Matching mounting method (through hole), orientation (vertical), and termination (solder)
• Identical shielding classification (unshielded) and category rating (Cat3)
• Equivalent contact material, finish specification, and housing composition
• Matching operating temperature range (-40°C to 70°C)
• Identical mechanical features (board lock, panel stops, user-selectable tab direction)

The substitution is based on complete electrical and mechanical compatibility across all specified parameters. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The 90512-003LF is the appropriate selection for new designs and production continuity. The main part (90512-003) is classified as obsolete, creating supply chain risk for ongoing applications. The substitute part maintains complete electrical and mechanical compatibility while offering:

• Active production status with established supply chain availability
• RoHS compliance certification
• REACH compliance status
• Tube packaging format suitable for automated assembly processes
• Identical performance specifications across all electrical and mechanical parameters

For applications currently using the 90512-003, direct substitution with the 90512-003LF requires no design modifications or PCB layout changes.

Frequently Asked Questions (FAQ)

Q: Can the 90512-003LF be used as a direct replacement for the 90512-003 without PCB modifications?

A: Yes. Both parts share identical connector type, contact configuration, mounting method, orientation, and termination specifications. No PCB layout or design changes are required.

Q: What is the primary reason for substitution?

A: The 90512-003 is classified as obsolete. The 90512-003LF is the active production equivalent with identical specifications and improved availability.

Q: Are there compliance differences between the two parts?

A: The 90512-003LF includes RoHS and REACH compliance certifications. The main part does not specify these certifications. Both parts share identical electrical and mechanical specifications.

Q: Does packaging format affect compatibility?

A: No. The packaging difference (tube for the 90512-003LF versus unspecified for the 90512-003) does not affect electrical or mechanical performance. Packaging selection depends on assembly process requirements and inventory management practices.

Q: Are the contact finish specifications identical?

A: Yes. Both parts feature gold-plated copper alloy contacts with 5.00µin (0.127µm) finish thickness, ensuring equivalent signal integrity and connection reliability.

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

A: Both the 90512-003 and 90512-003LF operate across -40°C to 70°C, providing identical thermal performance characteristics.
