Key Parameters

Substitute Part Grouping Explanation

Substitution of the 89074-185 is determined by strict equivalence across the following critical parameters:

• Position Count & Pitch: 48 positions at 0.079" (2.00mm) spacing
• Physical Configuration: 4-row through-hole header with male pins
• Electrical Characteristics: 1A current rating, gold contact finish at 30.0µin thickness
• Environmental Ratings: Operating range -55°C to 125°C, UL94 V-0 flammability
• Termination Method: Press-fit termination for PCB mounting

The substitute part 89074-185LF maintains identical electrical and mechanical specifications while offering improved regulatory compliance and active product status.

Parameter Comparison

Engineering Selection Recommendations

The 89074-185LF is the direct functional equivalent of the 89074-185 for all electrical and mechanical applications. Selection between these parts is determined by regulatory and supply chain requirements:

Use 89074-185LF for:

• New designs and production runs
• Applications requiring RoHS compliance
• Systems subject to REACH regulations
• Projects requiring active product status and ongoing manufacturer support

Use 89074-185 only for:

• Legacy system maintenance where RoHS non-compliance is acceptable
• Existing inventory utilization in non-regulated applications

Both parts are electrically and mechanically interchangeable within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Are the 89074-185 and 89074-185LF mechanically interchangeable?

A: Yes. Both connectors have identical position counts (48), pitch (0.079"), row configuration (4 rows), mounting type (through-hole), and termination method (press-fit). Physical dimensions and PCB footprints are equivalent.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and regulatory compliance. The 89074-185LF is RoHS compliant and REACH affected, while the 89074-185 is RoHS non-compliant and REACH unaffected. The 89074-185LF is active; the 89074-185 is obsolete. Electrical and mechanical specifications are identical.

Q: Can I use the 89074-185LF as a direct replacement in existing designs?

A: Yes. The 89074-185LF maintains all electrical characteristics (1A current rating, gold contact finish, operating temperature -55°C to 125°C) and mechanical specifications (48 positions, 2.00mm pitch, through-hole mounting) of the original 89074-185.

Q: What does the "LF" suffix indicate?

A: The "LF" suffix indicates lead-free composition and RoHS compliance. This designation reflects the part's compliance with the Restriction of Hazardous Substances directive.

Q: Are there packaging differences between these parts?

A: Yes. The 89074-185 is supplied in bulk packaging, while the 89074-185LF is supplied in tube packaging. This does not affect electrical or mechanical performance.

Q: Which part should I specify for new designs?

A: Specify the 89074-185LF for new designs. It offers active product status, RoHS compliance, and ongoing manufacturer support, ensuring long-term supply chain reliability and regulatory alignment.
