Substitute Part Grouping Explanation

Substitution of the 50003-1300H is determined by strict equivalence across the following critical parameters:

• Connector Type & Style: Receptacle with female sockets in high-density configuration (HPC™ series)
• Position Count & Configuration: 300 positions arranged in 4 rows × 75 columns
• Pitch & Spacing: 0.100" (2.54mm) pitch maintained for PCB compatibility
• Mounting & Termination: Through-hole, right-angle orientation with solder termination
• Contact Specifications: Gold finish at 30.0µin thickness with mating guide feature

The primary substitute identified is the 50003-1300HLF, which maintains identical electrical and mechanical specifications while offering active product status and RoHS compliance. This substitution is valid for applications where the connector footprint, pin count, and interface requirements remain unchanged.

Engineering Selection Recommendations

The 50003-1300HLF serves as the direct active equivalent to the obsolete 50003-1300H. Selection of the substitute part is appropriate for the following conditions:

• New Designs: The 50003-1300HLF is the recommended choice for new backplane connector implementations, offering active product status and continued manufacturer support.
• RoHS Compliance Requirements: Applications subject to RoHS directives must transition to the 50003-1300HLF, as the original part does not meet compliance standards.
• Existing System Maintenance: For systems currently using the 50003-1300H, the 50003-1300HLF provides a direct replacement without requiring PCB redesign, given the identical mechanical and electrical specifications.
• Supply Chain Continuity: With 649 units in stock, the 50003-1300HLF ensures availability for production and support applications.

Frequently Asked Questions (FAQ)

Q: Can the 50003-1300HLF be used as a direct replacement for the 50003-1300H?

A: Yes. Both parts maintain identical connector type, position count, pitch, mounting configuration, and contact specifications. PCB footprints and mating interfaces are compatible without modification.

Q: What is the significance of the "LF" suffix in the part number 50003-1300HLF?

A: The "LF" designation indicates lead-free and RoHS-compliant construction. This reflects the material composition and environmental compliance status of the connector.

Q: Are there electrical performance differences between these parts?

A: No. Both connectors share identical electrical specifications including contact finish, pitch, and configuration. Performance in signal integrity and current-carrying capacity remains equivalent.

Q: What is the impact of the obsolete status of the 50003-1300H?

A: Obsolete status indicates the part is no longer in active production. The 50003-1300HLF is the active continuation, ensuring long-term availability and manufacturer support for new applications and system maintenance.

Q: Is the MSL rating the same for both parts?

A: Yes. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: Can existing inventory of 50003-1300H be mixed with 50003-1300HLF in production?

A: From a mechanical and electrical standpoint, yes. However, RoHS compliance requirements may restrict mixing in regulated applications. Verify compliance requirements for your specific application.
