Engineering Selection Recommendations
Mercury United Electronics 634 Series (634-062-263-042, 634-062-263-043, 634-062-663-042, 634-062-663-043)
The Mercury United Electronics 634 Series connectors provide direct mechanical and electrical compatibility with the TE Connectivity 2-5748394-4. These parts maintain the same 62-position, 3-row, high-density D-Sub configuration with right-angle solder termination and gold-plated contacts. Selection among the four Mercury variants depends on specific flange and contact material requirements for the application. These parts are suitable for applications where the original TE Connectivity connector is unavailable.
Amphenol ICC HD Series (L177HDC62SD1CH3F, L177HDC62SD1CH3R, L177HDC62SD1CH4R, L77HDC62SD1CH3F, L77HDC62SD1CH3FC309, L77HDC62SD1CH3R)
The Amphenol ICC HD Series connectors offer enhanced electrical performance with 3A current rating and 250V voltage rating, exceeding the original part specifications. All Amphenol variants are active products with RoHS compliance certification. The L177HDC62 and L77HDC62 base product numbers represent different connector families within the HD Series. Selection among these variants depends on flange feature requirements (mating side female screwlock M3, board side M3, or board side 4-40) and contact material preference (brass or phosphor bronze).
Product Status Consideration
The original TE Connectivity 2-5748394-4 is classified as obsolete. All Amphenol ICC substitute parts are active products with current manufacturing support and RoHS compliance. Mercury United Electronics parts provide equivalent functionality for applications requiring direct replacement of the obsolete TE Connectivity connector.
Compliance and Certification
All substitute parts maintain UL94 V-0 material flammability rating and MSL 1 (Unlimited) moisture sensitivity level, matching the original part specifications. Amphenol ICC parts carry RoHS Compliant certification, providing regulatory compliance for new designs and applications subject to RoHS requirements.
Frequently Asked Questions (FAQ)
Q: Can I use an Amphenol ICC HD Series connector as a direct replacement for the TE Connectivity 2-5748394-4?
A: Yes. The Amphenol ICC HD Series connectors (L177HDC62 and L77HDC62 families) are mechanically and electrically compatible with the TE Connectivity 2-5748394-4. All critical parameters match: 62 positions, 3 rows, high-density D-Sub configuration, through-hole right-angle solder termination, gold-plated contacts, and UL94 V-0 flammability rating. The Amphenol parts exceed the original specifications with higher current rating (3A vs. 2A) and voltage rating (250V vs. 125V).
Q: What is the difference between the L177HDC62 and L77HDC62 Amphenol connector families?
A: Both families are 62-position, 3-row, high-density D-Sub receptacles with right-angle solder termination and gold-plated contacts. The primary differences are in the base product number designation and specific flange feature configurations available within each family. Selection between these families depends on the specific flange mounting requirements of the application.
Q: How do I select the correct flange feature variant?
A: Flange feature selection depends on the mechanical mounting requirements of your application. Available options include: Mating Side Female Screwlock (M3), Board Side (M3), and Board Side (4-40). The original TE Connectivity 2-5748394-4 uses Housing/Shell (4-40) flange feature. For direct replacement with matching flange configuration, select Amphenol part L177HDC62SD1CH4R or L77HDC62SD1CH3R variants with 4-40 board side mounting.
Q: Are Mercury United Electronics 634 Series connectors equivalent to Amphenol ICC HD Series connectors?
A: Both Mercury United and Amphenol ICC connectors are mechanically and electrically compatible with the TE Connectivity 2-5748394-4 and with each other. All maintain the same 62-position, 3-row, high-density D-Sub configuration with right-angle solder termination and gold-plated contacts. The primary difference is that Amphenol ICC parts are active products with RoHS compliance certification, while Mercury United parts provide equivalent functionality for applications requiring direct replacement.
Q: What is the significance of the contact material difference between Brass and Phosphor Bronze?
A: Both brass and phosphor bronze are acceptable contact materials for this connector category. The original TE Connectivity 2-5748394-4 uses phosphor bronze contacts. Amphenol ICC variants offer both materials: L177HDC62SD1CH3R and L77HDC62SD1CH3R use phosphor bronze, while L177HDC62SD1CH3F, L177HDC62SD1CH4R, L77HDC62SD1CH3F, and L77HDC62SD1CH3FC309 use brass. Selection depends on application-specific requirements for contact material properties.
Q: What does the contact finish thickness specification mean?
A: Contact finish thickness refers to the gold plating depth on the connector contacts. The original TE Connectivity 2-5748394-4 specifies Flash thickness. Amphenol ICC substitutes offer Flash, 16.0µin (0.41µm), and 30.0µin (0.76µm) thicknesses. All thicknesses provide adequate gold plating for electrical contact and corrosion resistance. Thicker plating (30.0µin) provides enhanced durability for high-cycle mating applications.
Q: Are the Mercury United 634 Series connectors RoHS compliant?
A: RoHS compliance status for Mercury United 634 Series connectors is not specified in the provided data. Amphenol ICC HD Series connectors are certified RoHS Compliant. For applications requiring RoHS compliance certification, Amphenol ICC parts are the recommended choice.
Q: Can I use a connector with higher current and voltage ratings as a substitute?
A: Yes. The Amphenol ICC HD Series connectors are rated for 3A current (vs. 2A original) and 250V voltage (vs. 125V original). Higher electrical ratings provide additional safety margin and are acceptable for applications designed for the original 2A/125V specifications. The connector will operate safely within the original design parameters while providing enhanced electrical capacity.
Q: What is the operating temperature range for substitute connectors?
A: The original TE Connectivity 2-5748394-4 operates from -55°C to 105°C. Most Amphenol ICC substitutes maintain this range. L177HDC62SD1CH3R extends the upper limit to 125°C. All substitute parts meet or exceed the original operating temperature specification.
Q: Are grounding tabs a required feature for substitution?
A: Grounding tabs are an additional feature present on most Amphenol ICC variants but not on the original TE Connectivity 2-5748394-4. Grounding tabs provide enhanced EMI/RFI shielding and are beneficial for applications requiring improved signal integrity. Their presence does not prevent substitution and provides additional functionality for compatible applications.
