L177DFDH50SAM4 Equivalent & Substitute Parts

Part Overview

The L177DFDH50SAM4 is a 50-position D-Sub receptacle connector manufactured by Amphenol ICC, featuring female sockets with right-angle solder termination and panel mount through-hole installation. This connector is classified as an active product with full RoHS compliance and is designed for signal applications requiring robust electrical and mechanical performance in industrial and commercial environments.

Substitute parts are identified when equivalent connectors share the same functional specifications: 50-position D-Sub receptacle configuration, female socket contact type, right-angle mounting orientation, solder termination method, and compatible shell size (DD/D, Size 5). Alternative sources become necessary due to inventory availability, supply chain optimization, or design flexibility requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the L177DFDH50SAM4 is determined by strict equivalence across the following mandatory parameters:

Connector Configuration: All substitute parts must be D-Sub style receptacles with 50 positions arranged in 3 rows, shell size 5 (DD/D layout), and female socket contact configuration.

Mounting and Termination: Substitutes must feature right-angle orientation, panel mount installation with through-hole capability, and solder termination to ensure direct PCB integration compatibility.

Contact Specifications: All substitutes must use machined contact form and signal-grade contact type to maintain electrical performance characteristics.

Packaging Format: Substitute parts must be supplied in tray packaging to align with handling and storage requirements.

The identified substitute part 174-E50-213R001 (NorComp Inc.) meets all mandatory configuration parameters, enabling direct functional replacement in applications where the primary part is unavailable.

Parameter Comparison

Engineering Selection Recommendations

Both the L177DFDH50SAM4 and 174-E50-213R001 are active products with full regulatory compliance. The L177DFDH50SAM4 maintains RoHS compliance and carries a current rating of 7.5A with operating temperature range of -55°C to 125°C. The 174-E50-213R001 is ROHS3 compliant with a current rating of 5A and operating temperature range of -50°C to 100°C.

Selection between these parts should be based on application-specific electrical requirements. The L177DFDH50SAM4 is suitable for applications requiring higher current capacity (7.5A) and extended low-temperature operation (-55°C). The 174-E50-213R001 is appropriate for applications within its rated specifications (5A, -50°C to 100°C) where NorComp supply chain availability is preferred.

Both parts satisfy identical mechanical and functional requirements for 50-position D-Sub receptacle applications with right-angle solder termination. Regulatory compliance and export classification (EAR99) are equivalent across both options.

Frequently Asked Questions (FAQ)

Q: Can the 174-E50-213R001 directly replace the L177DFDH50SAM4 in all applications?

A: Direct replacement is possible for applications operating within the 174-E50-213R001 specifications: maximum current 5A and operating temperature range -50°C to 100°C. Applications requiring the L177DFDH50SAM4's higher current rating (7.5A) or extended low-temperature operation (-55°C) require the original part.

Q: What are the differences in shell material finish between these parts?

A: The L177DFDH50SAM4 features tin-plated steel shell material, while the 174-E50-213R001 uses nickel-plated steel. Both configurations provide corrosion resistance; material selection depends on specific environmental exposure requirements and application standards.

Q: Are both parts compatible with the same PCB footprint?

A: Both parts share identical connector configuration (50-position D-Sub, Size 5, right-angle solder termination) and are designed for panel mount through-hole installation. PCB footprint compatibility is maintained. However, backset spacing differs: L177DFDH50SAM4 at 0.319" (8.10mm) versus 174-E50-213R001 at 0.370" (9.40mm). Verify PCB layout accommodates the specific backset spacing of the selected part.

Q: Do both parts meet the same regulatory standards?

A: Both parts are RoHS compliant (L177DFDH50SAM4 is RoHS Compliant; 174-E50-213R001 is ROHS3 Compliant), REACH Unaffected, and classified as EAR99 for export purposes. Both carry UL94 V-0 flammability rating. Regulatory compliance is equivalent for standard applications.

Q: What is the significance of the contact material difference (Copper Alloy vs. Brass)?

A: Both materials are standard for D-Sub connectors and provide adequate electrical conductivity and durability. Contact material selection does not affect functional compatibility. Both parts feature gold contact finish for enhanced corrosion resistance and signal integrity.
