Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 58355-144 is determined by strict equivalence across the following critical parameters:

• Position Count & Layout: 96 positions in 4-row by 24-column configuration
• Pitch Spacing: 0.079" (2.00mm) center-to-center distance
• Connector Type: Header with male pins
• Mounting Method: Through-hole with press-fit termination
• Contact System: Gold-plated finish at 30.0µin thickness
• Flammability Compliance: UL94 V-0 rating
• Series Compatibility: Metral® series

The substitute part 58355-144LF maintains all critical mechanical and electrical parameters required for direct functional replacement. The primary distinction is the active product status of the substitute, along with enhanced electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 58355-144LF is the direct active substitute for the obsolete 58355-144. Selection of the substitute part is justified on the following grounds:

Product Status: The 58355-144 is classified as obsolete, creating supply chain risk. The 58355-144LF maintains active product status with confirmed inventory availability.

Mechanical Compatibility: Both parts share identical position counts, pitch spacing, row/column configuration, and mounting methodology, ensuring direct PCB compatibility without layout modifications.

Electrical Performance: The 58355-144LF provides enhanced current rating (1.5A versus 1A), representing improved electrical capacity while maintaining all other contact specifications.

Compliance & Certifications: Both parts meet UL94 V-0 flammability requirements. The substitute adds RoHS compliance certification, meeting modern regulatory requirements.

Thermal Specification: The 58355-144LF includes defined operating temperature range (-55°C ~ 125°C), providing explicit thermal performance documentation absent in the main part specification.

Frequently Asked Questions (FAQ)

Q: Can the 58355-144LF be used as a direct replacement for the 58355-144 without PCB redesign?

A: Yes. Both connectors share identical position counts (96), pitch spacing (2.00mm), row/column configuration (4×24), and through-hole mounting specifications. No PCB layout modifications are required.

Q: What is the significance of the higher current rating on the 58355-144LF?

A: The substitute part supports 1.5A per contact versus 1A on the main part. This represents enhanced electrical capacity. If the original design operates at or near 1A per contact, the substitute provides additional margin. If the design requires exactly 1A, the substitute remains fully compatible.

Q: Does the RoHS compliance of the 58355-144LF affect compatibility?

A: No. RoHS compliance is an environmental and regulatory attribute that does not alter mechanical or electrical interface characteristics. The substitute is fully compatible with designs originally specified for the non-RoHS main part.

Q: Are there packaging differences between these parts?

A: The main part packaging is not specified. The substitute is supplied in tube packaging. Verify tube packaging compatibility with your assembly process requirements.

Q: What is the significance of the operating temperature specification on the substitute?

A: The 58355-144LF includes explicit operating temperature range (-55°C ~ 125°C). The main part does not specify this parameter. If your application requires operation outside this range, this must be evaluated against your specific thermal requirements.

Q: Are both parts from the same manufacturer?

A: Yes. Both are manufactured by Amphenol ICC (FCI) and belong to the Metral® series, ensuring design consistency and supply chain continuity within the same product family.
