Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 58355-151 is determined by strict equivalence across the following critical parameters:

• Connector Configuration: 96 positions, 4 rows × 24 columns
• Pitch Specification: 0.079" (2.00mm)
• Connector Type: Header with male pins
• Mounting Method: Through-hole PCB mounting
• Termination Technology: Press-fit contacts
• Contact Material & Finish: Gold plating at 30.0µin (0.76µm) thickness
• Flammability Compliance: UL94 V-0 rating
• Moisture Sensitivity: MSL 1 (Unlimited)

The substitute part 58355-151LF maintains full equivalence across all these parameters while offering enhanced electrical performance and active product status with extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The 58355-151LF serves as the direct substitute for the obsolete 58355-151. Both components share identical mechanical and electrical specifications across all critical parameters that determine PCB-level compatibility: connector position count, pitch, mounting method, and contact configuration.

The 58355-151LF offers the following advantages:

• Active Product Status: Ensures long-term availability and manufacturing support
• Enhanced Current Rating: 1.5A versus 1A on the original part, providing increased electrical capacity within the same form factor
• Defined Operating Temperature Range: -55°C ~ 125°C specification enables thermal performance validation
• RoHS Compliance: Meets current environmental and regulatory requirements
• Packaging: Supplied in tube format for automated assembly processes

Selection of the 58355-151LF is appropriate for applications requiring the Metral® 96-position header connector family with through-hole termination and gold-plated contacts.

Frequently Asked Questions (FAQ)

Q: Are the 58355-151 and 58355-151LF mechanically interchangeable?

A: Yes. Both parts maintain identical connector configuration (96 positions, 4×24 arrangement), pitch spacing (0.079"), mounting type (through-hole), and termination method (press-fit). PCB footprints and mating interface specifications are equivalent.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and electrical performance. The 58355-151LF is an active product with a higher current rating (1.5A versus 1A), defined operating temperature range (-55°C ~ 125°C), and RoHS compliance. The 58355-151 is obsolete.

Q: Can I use the 58355-151LF in a design originally specified for the 58355-151?

A: Yes. The 58355-151LF meets or exceeds all electrical and mechanical parameters of the original part. The enhanced current rating and temperature specification provide additional design margin.

Q: What does the "LF" suffix indicate?

A: The "LF" designation indicates lead-free contact plating, consistent with RoHS compliance requirements.

Q: Are there any compatibility concerns with existing PCB designs?

A: No. Both parts use identical pitch, row/column configuration, and through-hole mounting specifications. Existing PCB layouts require no modification.

Q: What is the packaging difference?

A: The 58355-151LF is supplied in tube packaging, suitable for automated pick-and-place assembly. The original 58355-151 packaging specification was not provided.
