Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 58355-129 is determined by strict equivalence across the following critical parameters:

• Position Count & Pitch: 48 positions at 0.079" (2.00mm) pitch
• Physical Configuration: 4 rows × 12 columns arrangement
• Connector Type & Termination: Header with male pins, press-fit termination
• Mounting Method: Through-hole PCB mounting
• Electrical Ratings: 1A current capacity
• Contact Specifications: Gold plating at 30.0µin (0.76µm) thickness
• Compliance: UL94 V-0 flammability rating

The substitute part 58355-129LF maintains full electrical and mechanical compatibility with the original specification while offering active product status and extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The 58355-129LF is the direct substitute for the obsolete 58355-129. Both components share identical electrical and mechanical specifications across all critical parameters: 48-position configuration, 2.00mm pitch, through-hole mounting, press-fit termination, and 1A current rating with gold-plated contacts.

The 58355-129LF offers two additional advantages: active product status ensuring continued availability and supply chain support, and RoHS compliance certification. The extended operating temperature range of -55°C to 125°C provides broader environmental applicability compared to the unspecified temperature range of the original part.

For applications requiring the 58355-129, the 58355-129LF provides full functional and mechanical interchangeability with enhanced compliance and availability characteristics.
