Key Parameters

Substitute Part Grouping Explanation

Substitution of the 58355-127 is determined by strict equivalence across the following critical parameters:

• Connector Position Count: 48 positions maintained
• Position Loading: 26 positions loaded configuration
• Pitch Specification: 0.079" (2.00mm) pitch required
• Physical Layout: 4 rows × 12 columns geometry
• Connector Type: Header with male pins
• Mounting Method: Through-hole PCB mounting
• Termination Style: Press-fit contact termination
• Contact Material: Gold plating at 30.0µin (0.76µm) thickness
• Flammability Compliance: UL94 V-0 rating

The direct substitute 58355-127LF maintains all these critical parameters while offering enhanced electrical performance and active product status.

Parameter Comparison

Engineering Selection Recommendations

The 58355-127LF serves as the direct functional equivalent to the obsolete 58355-127. Both components share identical mechanical and electrical specifications across all critical substitution parameters: 48-position configuration, 0.079" pitch, 4×12 layout, through-hole mounting, and press-fit termination.

The 58355-127LF offers the following advantages for component selection:

• Active Product Status: Currently manufactured and supported by Amphenol ICC, ensuring long-term availability and supply chain continuity
• Enhanced Current Rating: 1.5A rating compared to 1A in the original part, providing increased electrical capacity for the same physical form factor
• Regulatory Compliance: RoHS compliant designation and REACH affected status indicate current manufacturing standards compliance
• Operating Temperature Range: Specified temperature range of -55°C to 125°C provides explicit thermal operating boundaries
• Packaging: Supplied in tube packaging format

For applications requiring the 58355-127, the 58355-127LF is the recommended direct replacement without design modification.

Frequently Asked Questions (FAQ)

Q: Can the 58355-127LF be used as a direct replacement for the 58355-127?

A: Yes. Both parts maintain identical position count (48), pitch (0.079"), row/column configuration (4×12), connector type (header male pins), mounting method (through-hole), and termination style (press-fit). The 58355-127LF is electrically and mechanically compatible.

Q: What is the difference in current rating between these parts?

A: The 58355-127 is rated for 1A, while the 58355-127LF is rated for 1.5A. The 58355-127LF provides 50% higher current capacity within the same physical envelope.

Q: Why is the 58355-127 listed as obsolete?
