Substitute Part Grouping Explanation

Substitution of the 51740-10302403CC is determined by strict equivalence across the following critical parameters:

• Connector Series & Type: Must be PwrBlade® receptacle with female sockets and blade sockets configuration
• Position Count & Layout: Exactly 30 positions with 24 signal and 6 power contact arrangement
• Pitch & Geometry: 0.100" (2.54mm) pitch with 4-row configuration
• Mounting & Termination: Through-hole mounting with press-fit termination
• Electrical & Environmental Ratings: UL94 V-0 flammability, -20°C to 105°C operating range, MSL 1
• Contact Specifications: Gold or Gold GXT™ finish at 30.0µin thickness

The substitute part 51740-10302403CCLF maintains identical electrical and mechanical specifications while differing in product status (active vs. obsolete) and packaging format (tray vs. standard packaging). This substitution is valid for direct replacement in applications where the original part is no longer available.

Engineering Selection Recommendations

The 51740-10302403CCLF is the direct functional equivalent of the 51740-10302403CC. Selection between these parts should be based on the following criteria:

For New Designs and Ongoing Production: The 51740-10302403CCLF is the preferred choice. This part carries active product status, ensuring long-term availability and supply chain stability. It meets RoHS compliance requirements, which may be mandated by regulatory frameworks or customer specifications. The tray packaging format supports efficient handling in automated assembly environments.

For Legacy System Support: The 51740-10302403CC remains suitable for repair and maintenance of existing installations where the original part specification is required. However, given its obsolete status, procurement should prioritize the substitute part to avoid future supply constraints.

Compliance Considerations: Organizations subject to RoHS directives should transition to the 51740-10302403CCLF. Both parts maintain identical electrical performance, mechanical fit, and environmental ratings, ensuring seamless integration without design modification.

Frequently Asked Questions (FAQ)

Q: Can the 51740-10302403CCLF be used as a direct replacement for the 51740-10302403CC?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters: 30-position configuration, 0.100" pitch, 4-row layout, through-hole press-fit termination, 24 signal and 6 power contact arrangement, and identical operating temperature range. The substitute part differs only in product status (active vs. obsolete) and packaging format (tray vs. standard).

Q: What is the significance of the RoHS compliance difference?

A: The 51740-10302403CCLF is RoHS compliant, meaning it meets restrictions on hazardous substances as defined by applicable regulations. The original part is RoHS non-compliant. For applications subject to RoHS requirements, the substitute part is the appropriate selection.

Q: Are there any packaging considerations when switching to the substitute part?

A: The 51740-10302403CCLF is supplied in tray packaging, while the original part uses standard packaging. Tray packaging is optimized for automated assembly processes and provides improved component protection during storage and handling. This change does not affect the connector's electrical or mechanical performance.

Q: What is the contact finish specification, and does it differ between the two parts?

A: Both parts feature gold or gold GXT™ contact finish with a thickness of 30.0µin (0.76µm). This specification is identical across both part numbers and ensures consistent electrical performance and corrosion resistance.

Q: Are there any environmental or temperature limitations I should be aware of?

A: Both parts operate across the identical temperature range of -20°C to 105°C and maintain UL94 V-0 flammability rating. Moisture sensitivity level is 1 (unlimited) for both parts, indicating no special moisture handling requirements during storage or assembly.

Q: What does the "LF" suffix in the substitute part number indicate?

A: The "LF" suffix typically indicates lead-free construction, which aligns with RoHS compliance requirements. This is a standard industry designation for parts manufactured without lead-based solder or finishes.
