Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 51416-003 is determined by strict equivalence across the following critical parameters:

• Connector type: Receptacle with female sockets and blade sockets
• Position count: 26 positions
• Pitch specification: 0.100" (2.54mm)
• Row configuration: 4 rows
• Mounting method: Board edge, through-hole, right-angle orientation
• Contact layout: 24 signal, 2 power distribution
• Contact finish material and thickness: Gold or Gold, GXT™ at 30.0µin (0.76µm)
• Operating temperature range: -20°C ~ 105°C
• Flammability rating: UL94 V-0

The substitute part 51416-003LF meets all these criteria and is therefore a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 51416-003LF is the direct substitute for the obsolete 51416-003. Both parts are manufactured by Amphenol ICC and share identical electrical and mechanical specifications across all critical parameters.

The primary distinction between these parts is product status and compliance posture. The 51416-003 is obsolete and RoHS non-compliant, while the 51416-003LF is active and RoHS compliant. The 51416-003LF also carries REACH Affected status, indicating compliance with European chemical regulations.

For new designs or ongoing production requiring this connector type, the 51416-003LF is the appropriate selection. For legacy systems currently using the 51416-003, the 51416-003LF provides functional equivalence with improved regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the 51416-003LF be used as a direct replacement for the 51416-003?

A: Yes. The 51416-003LF is a direct functional equivalent. All electrical and mechanical parameters are identical, including connector type, position count, pitch, mounting configuration, contact layout, contact finish, and operating temperature range.

Q: What is the difference between the 51416-003 and 51416-003LF?

A: The primary differences are product status and regulatory compliance. The 51416-003 is obsolete and RoHS non-compliant. The 51416-003LF is active, RoHS compliant, and REACH affected. Functionally and mechanically, both parts are equivalent.

Q: Are there packaging differences between these parts?

A: The 51416-003 packaging information is not specified in the available data. The 51416-003LF is supplied in Tray packaging.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is based on equivalence across connector type, position count (26), pitch (0.100" / 2.54mm), row configuration (4), mounting type (board edge, through-hole, right-angle), contact layout (24 signal, 2 power), contact finish (Gold or Gold, GXT™ at 30.0µin), operating temperature range (-20°C ~ 105°C), and flammability rating (UL94 V-0).

Q: Is the 51416-003LF suitable for applications requiring RoHS compliance?

A: Yes. The 51416-003LF is RoHS compliant, making it suitable for applications with RoHS requirements. The original 51416-003 is RoHS non-compliant.

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

A: Both the 51416-003 and 51416-003LF have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture control requirements.
