Key Parameters

Substitute Part Grouping Explanation

Substitution of the 53612-S50-7 is determined by strict alignment of the following critical parameters:

• Connector Type & Contact Type: Must be Header with Male Pin contacts
• Position Count & Row Configuration: Must maintain 50 positions in 2 rows
• Pitch Specifications: Mating pitch and row spacing must both be 0.100" (2.54mm)
• Mounting & Termination: Through-hole solder termination required
• Shrouding & Fastening: 4-wall shrouded design with latch lock/eject hooks
• Contact Material & Shape: Phosphor bronze with square contact geometry

The substitute part EJH-125-01-F-D-TH-01 from Samtec Inc. meets all these core electrical and mechanical parameters, enabling direct functional replacement in applications currently using the 53612-S50-7.

Engineering Selection Recommendations

The EJH-125-01-F-D-TH-01 from Samtec Inc. is the qualified substitute for the obsolete 53612-S50-7. Selection is based on the following engineering factors:

Product Status: The 53612-S50-7 is obsolete, while the EJH-125-01-F-D-TH-01 is active and currently manufactured, ensuring long-term availability and supply chain continuity.

Regulatory Compliance: The substitute part is ROHS3 compliant, whereas the original part is RoHS non-compliant. This addresses modern regulatory requirements for new designs and procurement cycles.

Functional Equivalence: Both connectors share identical core specifications for connector type, contact configuration, pitch, mounting method, and shrouding design, ensuring mechanical and electrical compatibility in existing applications.

Performance Specifications: The substitute provides defined operating temperature range (-55°C ~ 125°C) and current rating (3A), offering documented performance parameters absent in the original part specification.

Frequently Asked Questions (FAQ)

Q: Can the EJH-125-01-F-D-TH-01 be used as a direct replacement for the 53612-S50-7?

A: Yes. Both connectors share identical pitch (0.100" / 2.54mm), position count (50 in 2 rows), mounting type (through-hole), shrouding (4-wall), and fastening mechanism (latch lock/eject hooks). The connectors are mechanically and electrically compatible for board-to-cable/wire applications.

Q: What are the key differences between these two parts?

A: The primary differences are product status, regulatory compliance, and documented performance specifications. The 53612-S50-7 is obsolete and RoHS non-compliant, while the EJH-125-01-F-D-TH-01 is active, ROHS3 compliant, and includes specified operating temperature range and current rating. The substitute also uses Liquid Crystal Polymer (LCP) insulation instead of thermoplastic.

Q: Are there packaging differences between the original and substitute?

A: Yes. The 53612-S50-7 packaging is not specified, while the EJH-125-01-F-D-TH-01 is supplied in tube packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Does the number of positions loaded affect substitution?

A: The 53612-S50-7 has all 50 positions loaded, while the EJH-125-01-F-D-TH-01 has 49 positions loaded. This difference does not affect functional compatibility if your application uses 49 or fewer positions. Confirm position requirements for your specific design.

Q: What is the impact of different contact finish specifications?

A: The 53612-S50-7 features gold mating contact finish (15.0µin thickness) with tin-lead post finish. The EJH-125-01-F-D-TH-01 has gold mating contact finish (3.00µin thickness) with tin post finish. Both provide adequate electrical contact and corrosion resistance for standard applications. The thinner gold plating on the substitute is within industry standards for 2.54mm pitch connectors.
