Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 87409-105 is determined by strict equivalence across the following critical parameters:

• Connector type, contact type, and gender (Header, Male Pin)
• Position count and row configuration (10 positions, 2 rows)
• Mating pitch and row spacing (0.050" / 1.27mm)
• Mounting technology (Surface Mount)
• Board-to-board style with shrouded 4-wall construction
• Push-pull fastening mechanism
• Solder termination
• Operating temperature range (-55°C ~ 130°C)
• Flammability rating (UL94 V-0)
• Insulation material composition (Thermoplastic, Glass Filled)
• Contact finish specification (Gold or Gold, GXT™ for mating surface)
• Mated stacking height (6.42mm)

The 87409-105LF qualifies as a direct substitute based on full alignment with all critical parameters listed above.

Parameter Comparison

Engineering Selection Recommendations

The 87409-105LF is the direct equivalent substitute for the obsolete 87409-105. Both components share identical mechanical and electrical specifications across all critical parameters including connector geometry, pitch, mounting technology, and operating temperature range.

The primary distinction between these parts is product status and regulatory compliance. The 87409-105LF carries active product status with RoHS compliance and REACH applicability, whereas the 87409-105 is obsolete and RoHS non-compliant. The 87409-105LF also specifies a current rating of 1A (DC) and uses tin post finish instead of tin-lead, reflecting modern manufacturing standards.

For new designs or component replenishment, the 87409-105LF is the appropriate selection. The connector maintains full mechanical and electrical compatibility with existing board designs utilizing the 87409-105, with the added benefit of current product availability and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the 87409-105LF be used as a direct replacement for the 87409-105 in existing assemblies?

A: Yes. The 87409-105LF is mechanically and electrically equivalent to the 87409-105. Both connectors feature identical 10-position, 2-row configuration at 0.050" pitch, surface mount construction, and operating temperature range. The components are interchangeable at the board level.

Q: What is the difference between the contact finish specifications?

A: The 87409-105 uses tin-lead post finish, while the 87409-105LF uses tin post finish. Both maintain the same gold or gold GXT™ mating surface finish at 30.0µin thickness. The post finish difference reflects the transition to lead-free manufacturing standards in the 87409-105LF.

Q: Why is the 87409-105 listed as obsolete?

A: The 87409-105 has been superseded by the 87409-105LF, which offers improved regulatory compliance (RoHS compliant) and modern manufacturing specifications. The 87409-105LF is the active product variant within the Rib-Cage™ III series for this connector configuration.

Q: Does packaging differ between these parts?

A: The 87409-105LF is supplied in tube packaging. The original 87409-105 packaging specification is not provided in the technical data. Confirm packaging requirements with your procurement process.

Q: Are there any temperature or environmental limitations when substituting these connectors?

A: Both connectors operate across the identical temperature range of -55°C to 130°C and carry UL94 V-0 flammability rating. Moisture sensitivity level is 1 (Unlimited) for both parts, indicating no special moisture handling requirements during storage or assembly.
