Key Parameters

Substitute Part Grouping Explanation

Substitution of the 58355-149 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility:

• Connector type (Header, Male Pins)
• Number of positions (96)
• Pitch spacing (0.079" / 2.00mm)
• Row configuration (4 rows)
• Mounting method (Through Hole)
• Termination style (Press-Fit)

Electrical & Material Compliance:

• Contact finish (Gold plating)
• Current rating (1A)
• Flammability rating (UL94 V-0)
• Series designation (Metral®)

The substitute part 58355-149LF meets all these criteria while offering an active product status and extended operating temperature specification, making it a direct functional equivalent for applications requiring the same physical and electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 58355-149LF is the direct equivalent substitute for the obsolete 58355-149. Both connectors share identical mechanical and electrical specifications within the Metral® series, ensuring pin-for-pin compatibility and functional interchangeability in PCB applications.

Selection Basis:

The 58355-149LF is recommended for new designs and replacement applications because:

1. Product Status: The substitute maintains active product status, ensuring continued availability and manufacturing support from Amphenol ICC (FCI).

2. Compliance: The 58355-149LF carries RoHS Compliant certification, meeting current regulatory requirements for electronic component procurement in regulated industries.

3. Operating Temperature: The substitute specifies an operating temperature range of -55°C to 125°C, providing explicit thermal performance data absent from the main part specification.

4. Mechanical & Electrical Equivalence: All critical parameters—connector type, position count, pitch, mounting method, termination style, contact finish, current rating, and flammability rating—are identical between the two parts.

For applications where the original 58355-149 is no longer available, the 58355-149LF provides direct substitution without design modification or PCB rework.

Frequently Asked Questions (FAQ)

Q: Can the 58355-149LF be used as a direct replacement for the 58355-149 in existing designs?

A: Yes. The 58355-149LF is mechanically and electrically equivalent to the 58355-149. Both connectors feature 96 positions, 0.079" (2.00mm) pitch, 4-row configuration, through-hole mounting, press-fit termination, and identical contact finish specifications. No design changes or PCB modifications are required.

Q: What is the primary difference between these two parts?

A: The 58355-149 is obsolete, while the 58355-149LF maintains active product status. Additionally, the 58355-149LF specifies an operating temperature range of -55°C to 125°C and carries RoHS Compliant certification. All functional and mechanical characteristics remain identical.

Q: Are the connector headers physically interchangeable?

A: Yes. Both connectors share the same physical dimensions, pin configuration, pitch spacing, and mounting footprint. They are fully interchangeable at the PCB level.

Q: Does the 58355-149LF require different PCB layout or footprint design?

A: No. The PCB footprint, hole spacing, and mounting requirements are identical for both parts. Existing PCB designs for the 58355-149 require no modification to accommodate the 58355-149LF.

Q: What does the "LF" designation in 58355-149LF indicate?

A: The "LF" suffix typically indicates lead-free compliance in Amphenol ICC part numbering. The 58355-149LF is RoHS Compliant, reflecting current environmental and regulatory standards for electronic components.

Q: Are there any electrical performance differences between the two connectors?

A: No. Both connectors maintain identical electrical specifications: 1A current rating, gold contact finish at 30.0µin (0.76µm) thickness, and UL94 V-0 flammability rating. Electrical performance is equivalent.

Q: What is the moisture sensitivity level for these connectors?

A: Both the 58355-149 and 58355-149LF carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
