Parameter Comparison

Engineering Selection Recommendations

The 58355-161LF is the direct substitute for the obsolete 58355-161. Both components share identical electrical and mechanical specifications across all critical parameters: position count, pitch, connector type, mounting method, and contact characteristics.

The 58355-161LF offers the following advantages:

• Active Product Status: Currently manufactured and supported by Amphenol ICC, ensuring long-term availability and supply chain continuity
• Enhanced Current Rating: 1.5A versus 1A in the original part, providing increased current-carrying capacity for the same form factor
• RoHS Compliance: The substitute meets RoHS requirements, supporting compliance with modern environmental regulations
• Defined Operating Temperature Range: Specified as -55°C to 125°C, providing clear thermal operating boundaries
• REACH Compliance Status: Documented REACH affected status ensures regulatory transparency

For new designs and legacy system replacements, the 58355-161LF is the appropriate selection. The enhanced current rating and active product status make it the preferred choice for applications requiring long-term component availability and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Are the 58355-161 and 58355-161LF mechanically interchangeable?

A: Yes. Both parts share identical mechanical specifications: 192 positions in 4×48 configuration, 0.079" (2.00mm) pitch, through-hole mounting, and press-fit termination. PCB footprints are identical.

Q: What is the difference between these two parts?

A: The primary differences are product status (obsolete versus active), current rating (1A versus 1.5A), and regulatory compliance documentation. The 58355-161LF includes specified operating temperature range (-55°C to 125°C) and RoHS compliance status.

Q: Can I use the 58355-161LF as a direct replacement in existing designs?

A: Yes. The 58355-161LF is electrically and mechanically equivalent to the 58355-161. The higher current rating (1.5A) and active product status make it suitable for direct substitution in legacy applications.

Q: What does "LF" in the part number 58355-161LF indicate?

A: The "LF" suffix typically indicates lead-free construction in Amphenol ICC nomenclature, supporting RoHS compliance requirements.

Q: Are there any compatibility concerns with PCB assembly?

A: No. Both parts use identical press-fit termination and through-hole mounting. Assembly processes and equipment settings remain unchanged.

Q: What is the significance of the MSL 1 rating?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life with no special moisture control requirements during storage or handling. Both parts carry this classification.
