Key Parameters

Substitute Part Grouping Explanation

Substitution of the 51915-044 is based on strict equivalence across the following critical parameters:

• Connector Configuration: 16-position receptacle with female sockets
• Pitch and Position Layout: 0.100" (2.54mm) pitch with 4-row configuration
• Mounting and Termination: Board edge mounting with through-hole, right-angle solder termination
• Contact Specifications: Gold or Gold, GXT™ finish at 30.0µin (0.76µm) thickness
• Environmental Ratings: UL94 V-0 flammability rating and -20°C ~ 105°C operating temperature range
• Mechanical Features: Guide pin inclusion and black color

The substitute part 51915-044LF maintains complete equivalence across all specified electrical and mechanical parameters. The primary distinction is product status and compliance certification, not functional or dimensional characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 51915-044LF is the direct functional equivalent of the 51915-044 across all electrical and mechanical specifications. Selection between these parts should be based on the following criteria:

For New Designs and Ongoing Production: The 51915-044LF is the appropriate selection. This part maintains active product status, ensuring continued availability and manufacturer support. The 51915-044LF carries RoHS compliance certification and REACH affected status, meeting current regulatory requirements for electronic component procurement.

For Legacy System Support: The 51915-044 remains functionally equivalent for applications where existing inventory is available. However, the obsolete status indicates limited future availability through standard distribution channels.

Both parts are manufactured by Amphenol ICC (FCI) within the PwrBlade® series and share identical connector architecture, contact specifications, and environmental ratings. The choice between them is determined by compliance requirements and supply chain considerations rather than functional performance.

Frequently Asked Questions (FAQ)

Q: Are the 51915-044 and 51915-044LF mechanically interchangeable?

A: Yes. Both connectors share identical mounting type (board edge, through-hole, right-angle), position count (16), pitch (0.100"), and row configuration (4). They are direct mechanical substitutes.

Q: What is the significance of the "LF" designation in the 51915-044LF part number?

A: The "LF" suffix indicates lead-free construction, which correlates with RoHS compliance. The 51915-044LF meets RoHS requirements, while the 51915-044 does not.

Q: Can I use the 51915-044 in applications requiring RoHS compliance?

A: No. The 51915-044 is RoHS non-compliant. Applications subject to RoHS regulations must use the 51915-044LF.

Q: Are there differences in contact performance between these parts?

A: No. Both parts specify identical contact finish (Gold or Gold, GXT™) at 30.0µin (0.76µm) thickness, operating temperature range (-20°C ~ 105°C), and flammability rating (UL94 V-0).

Q: What packaging options are available?

A: The 51915-044LF is supplied in tray packaging. Packaging specification for the 51915-044 is not provided in the technical data.

Q: Why is the 51915-044 classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production and support. The 51915-044LF represents the current production equivalent within the PwrBlade® series.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both connectors operate across the identical temperature range of -20°C ~ 105°C.
