Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 58355-124 is determined by strict equivalence across the following critical parameters:

• Position Count & Configuration: 48 positions in 4×12 arrangement
• Pitch Specification: 0.079" (2.00mm) center-to-center spacing
• Connector Type: Header with male pins
• Mounting Method: Through-hole PCB mounting
• Termination Style: Press-fit contact technology
• Contact Material & Finish: Gold plating at 30.0µin thickness
• Flammability Compliance: UL94 V-0 rating

The substitute part 58355-124LF maintains identical mechanical and electrical specifications across all critical parameters while offering enhanced performance characteristics and active product status.

Parameter Comparison

Engineering Selection Recommendations

The 58355-124LF serves as the direct substitute for the obsolete 58355-124. Both components share identical mechanical interfaces, electrical contact specifications, and flammability compliance. The 58355-124LF 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, providing increased current-carrying capacity within the same form factor
• Defined Operating Temperature Range: -55°C to 125°C specification enables precise thermal design validation
• RoHS Compliance: Meets current environmental and regulatory requirements for new designs and manufacturing processes
• Established Packaging: Supplied in tube packaging for standard component handling and assembly processes

For applications requiring the original 58355-124 specifications, the 58355-124LF provides direct functional equivalence with improved performance margins and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the 58355-124LF be used as a direct replacement for the 58355-124 in existing designs?

A: Yes. The 58355-124LF maintains identical mechanical dimensions, pitch, position count, mounting method, and contact specifications. The higher current rating (1.5A vs. 1A) and defined operating temperature range represent performance enhancements rather than compatibility changes.

Q: What is the significance of the "LF" designation in the part number?

A: The "LF" suffix indicates lead-free contact plating, reflecting current manufacturing standards and RoHS compliance. This does not affect mechanical or electrical compatibility with applications designed for the original 58355-124.

Q: Are there any thermal or environmental differences between these parts?

A: The 58355-124LF specifies an operating temperature range of -55°C to 125°C, whereas the original part does not provide this specification. Both components carry identical UL94 V-0 flammability ratings and MSL 1 moisture sensitivity levels.

Q: What packaging formats are available for the substitute part?

A: The 58355-124LF is supplied in tube packaging, which is standard for through-hole connector components and compatible with automated assembly processes.

Q: Are both parts compliant with current regulatory standards?

A: The 58355-124LF is RoHS compliant and carries current certifications. The original 58355-124, being obsolete, may not meet current regulatory requirements for new manufacturing or design implementations.
