• Row configuration: 4 rows
• Mounting method: Board edge, through-hole, right-angle orientation
• Termination method: Solder
• Contact layout: 24 signal, 16 power positions
• Contact finish: Gold or Gold, GXT™ at 30.0µin thickness
• Flammability rating: UL94 V-0
• Operating temperature range: -20°C ~ 105°C
• Series designation: PwrBlade®

The substitute part 51915-040LF maintains full electrical and mechanical compatibility with the original specification while offering improved product status and compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 51915-040LF is the direct substitute for the obsolete 51915-040. Both parts maintain identical electrical and mechanical specifications across all critical parameters including connector type, position count, pitch, mounting configuration, contact layout, and operating temperature range.

The 51915-040LF offers two significant advantages over the original part:

1. Active product status: The 51915-040LF is currently in active production, ensuring long-term availability and supply chain continuity.

2. Compliance improvement: The 51915-040LF is RoHS compliant and REACH affected, whereas the 51915-040 is RoHS non-compliant. For applications subject to environmental regulations or customer requirements mandating RoHS compliance, the 51915-040LF is the appropriate selection.

Both parts share identical contact finish specifications, flammability ratings, and thermal operating ranges, confirming full functional interchangeability in board-level applications.

Frequently Asked Questions (FAQ)

Q: Are the 51915-040 and 51915-040LF electrically and mechanically interchangeable?

A: Yes. Both parts are identical in connector type, position count, pitch, mounting method, contact layout, contact finish, and operating temperature range. They are fully interchangeable at the board level.

Q: What is the difference between the 51915-040 and 51915-040LF?

A: The primary differences are product status and compliance. The 51915-040 is obsolete and RoHS non-compliant. The 51915-040LF is active production and RoHS compliant. Packaging differs: the original uses bulk packaging while the substitute uses tray packaging.

Q: Why should I use the 51915-040LF instead of the 51915-040?

A: The 51915-040LF is recommended for new designs and ongoing production due to its active status and RoHS compliance. For legacy systems currently using the 51915-040, the 51915-040LF provides a compliant replacement without requiring design modifications.

Q: Does the tray packaging of the 51915-040LF affect compatibility?

A: No. Packaging format does not affect electrical or mechanical compatibility. Tray packaging is a handling and logistics consideration only.

Q: Are there any thermal or electrical performance differences between these parts?

A: No. Both parts operate across the identical temperature range of -20°C to 105°C and maintain the same contact finish specifications and flammability rating.
