Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 58355-164 is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Number of positions: 192 (fixed requirement)
• Pitch: 0.079" (2.00mm) (fixed requirement)
• Configuration: 4 rows × 48 columns (fixed requirement)
• Connector type: Header, Male Pins (fixed requirement)
• Mounting type: Through Hole (fixed requirement)
• Termination method: Press-Fit (fixed requirement)
• Series: Metral® (fixed requirement)
• Contact finish: Gold (fixed requirement)

Allowable Variations:

• Current rating: May increase from 1A to 1.5A (backward compatible)
• Operating temperature range: May be specified (enhancement)
• Contact finish thickness: Maintained at 30.0µin (0.76µm)
• Product status: May transition from Obsolete to Active
• RoHS compliance: May be added (enhancement)
• Color: May vary (Natural vs. unspecified)

The substitute part 58355-164LF maintains all critical parameters while offering improved electrical performance and active product status.

Parameter Comparison

Engineering Selection Recommendations

The 58355-164LF is the direct functional equivalent of the obsolete 58355-164. Selection of the substitute part is supported by the following factors:

Product Status: The 58355-164 is classified as obsolete, while the 58355-164LF maintains active product status with current manufacturing support and documented inventory availability (979 pcs in stock).

Electrical Performance: The substitute part provides equal or superior electrical characteristics. The current rating increases from 1A to 1.5A, representing a 50% improvement in current-carrying capacity while maintaining identical contact geometry and termination method.

Compliance and Certifications: Both parts maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity classification. The substitute part adds RoHS compliance certification, meeting modern regulatory requirements.

Physical and Mechanical Compatibility: All critical mechanical parameters remain unchanged: 192 positions, 0.079" (2.00mm) pitch, 4×48 configuration, through-hole mounting, and press-fit termination. PCB footprint and mounting hole patterns are identical.

Thermal Specification: The substitute part specifies an operating temperature range of -55°C to 125°C, providing defined thermal performance boundaries for system design.

For new designs and ongoing system support, the 58355-164LF is the appropriate selection. Existing assemblies using the 58355-164 may be retrofitted with the substitute part without PCB redesign or mechanical modification.

Frequently Asked Questions (FAQ)

Q: Can the 58355-164LF be used as a direct replacement for the 58355-164 in existing PCB assemblies?

A: Yes. The 58355-164LF is mechanically and electrically compatible with the 58355-164. All critical parameters—position count, pitch, configuration, mounting type, and termination method—are identical. PCB footprints and mounting hole patterns require no modification.

Q: What is the significance of the "LF" designation in the part number 58355-164LF?

A: The "LF" suffix indicates lead-free construction, reflecting RoHS compliance. This designation distinguishes the part from the original 58355-164 while maintaining functional equivalence.

Q: Does the increased current rating of 1.5A in the substitute part affect compatibility?

A: No. The higher current rating of the 58355-164LF (1.5A vs. 1A) represents improved electrical performance and is fully backward compatible. Systems designed for 1A operation will function correctly with the substitute part.

Q: Are there any packaging differences between the two parts?

A: The 58355-164 packaging is not specified in the available data. The 58355-164LF is supplied in tube packaging. Confirm packaging requirements for your procurement process.

Q: What is the inventory status for the substitute part?

A: The 58355-164LF has 979 pieces of new original stock currently available. The original 58355-164 has 1015 pieces in stock but is classified as obsolete with no ongoing manufacturing support.

Q: Are both parts manufactured by the same company?

A: Yes. Both the 58355-164 and 58355-164LF are manufactured by Amphenol ICC (FCI) and belong to the Metral® connector series.

Q: What operating temperature range should be used for system design?

A: The substitute part 58355-164LF specifies -55°C to 125°C operating temperature. The original 58355-164 does not provide a specified operating temperature range. Use the documented range of the substitute part for thermal design calculations.

Q: Is the substitute part suitable for new product designs?

A: Yes. The 58355-164LF is classified as an active product with current manufacturing support, RoHS compliance, and specified operating parameters. It is the appropriate choice for new designs requiring this connector type and configuration.
