Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the L717DD50PC are identified from NorComp Inc. based on the following critical matching parameters:

Mandatory Matching Criteria:

• Connector type: D-Sub plug with male pins
• Position count: 50 positions
• Row configuration: 3 rows
• Shell size: 5 (DD, D)
• Termination method: Solder
• Mounting style: Right angle
• Contact type: Signal
• Contact form: Machined
• Contact material: Brass
• Flammability rating: UL94 V-0
• Connector style: D-Sub

Allowable Parameter Variations: Substitute parts may differ in backset spacing, current rating, operating temperature range, shell material finish, contact finish thickness, and voltage rating specifications. These variations do not prevent functional substitution when application requirements permit.

The four identified substitute parts from NorComp Inc. (173-E50-113R001, 173-E50-113R141, 174-E50-113R001, 174-E50-113R141) maintain core connector topology and electrical characteristics while offering alternative mechanical configurations and thermal operating ranges.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status and comply with RoHS regulations. The L717DD50PC and all four NorComp substitute parts carry UL94 V-0 flammability certification, meeting safety requirements for general industrial and commercial applications.

Amphenol ICC L717DD50PC is suitable for applications requiring the full specified current rating of 7.5A, extended operating temperature range (-55°C to 125°C), and 300V voltage rating. The tin-plated steel shell and 8.00µin gold contact finish provide specified corrosion resistance characteristics.

NorComp 173-E50-113R001 and 173-E50-113R141 feature reduced backset spacing (0.283" versus 0.319"), supporting compact PCB layouts. The 173-E50-113R141 variant includes female screwlock mating connectors (4-40) and mounting brackets for panel-mount applications.

NorComp 174-E50-113R001 and 174-E50-113R141 feature increased backset spacing (0.370" versus 0.319"), accommodating applications with larger component clearance requirements. The 174-E50-113R141 variant includes female screwlock mating connectors (4-40) and mounting brackets for panel-mount applications.

All NorComp substitutes operate within -50°C to 100°C temperature range and carry 5A current rating. Applications requiring the full 7.5A rating or extended temperature extremes must retain the L717DD50PC specification.

Frequently Asked Questions (FAQ)

Q: Can NorComp substitute parts directly replace the L717DD50PC in all applications?

A: Direct replacement depends on application electrical and thermal requirements. The L717DD50PC supports 7.5A current rating and -55°C to 125°C operating range. NorComp substitutes are rated for 5A and -50°C to 100°C. Applications operating within the NorComp specifications permit substitution. Applications requiring the higher current rating or extended temperature range require the L717DD50PC.

Q: What is the significance of backset spacing differences between substitute parts?

A: Backset spacing defines the distance from the connector mounting plane to the solder pin termination points. The L717DD50PC specifies 0.319" (8.10mm). NorComp 173-E series parts specify 0.283" (7.20mm), and 174-E series parts specify 0.370" (9.40mm). PCB layout and component placement must accommodate the specified backset spacing. Incorrect spacing selection results in solder joint misalignment or component interference.

Q: What is the difference between unthreaded housing and female screwlock flange features?

A: Unthreaded housing (L717DD50PC, 173-E50-113R001, 174-E50-113R001) provides basic connector retention through friction fit. Female screwlock (173-E50-113R141, 174-E50-113R141) includes 4-40 threaded inserts on the mating connector side, enabling mechanical locking via threaded coupling. Screwlock variants include mounting brackets for panel-mount applications. Selection depends on application retention requirements and panel mounting necessity.

Q: Are shell material finish differences significant for substitution?

A: The L717DD50PC features tin-plated steel shell; NorComp substitutes feature nickel-plated steel shell. Both finishes provide corrosion resistance suitable for industrial environments. Tin plating offers superior solderability; nickel plating provides enhanced corrosion resistance in harsh environments. Application environment determines appropriate finish selection.

Q: What does contact finish thickness variation mean for connector performance?

A: The L717DD50PC specifies 8.00µin (0.203µm) gold contact finish thickness. NorComp substitutes specify flash gold finish (thickness not quantified). Flash finish provides adequate contact conductivity and corrosion resistance for standard signal applications. Applications requiring specified contact finish thickness or enhanced wear resistance should retain the L717DD50PC specification.

Q: How do dielectric material differences affect connector suitability?

A: The L717DD50PC uses thermoplastic glass-filled dielectric material. NorComp substitutes use polyamide (PA6T) nylon 6T dielectric. Both materials meet UL94 V-0 flammability requirements. Nylon 6T offers superior chemical resistance and dimensional stability. Thermoplastic glass-filled material provides enhanced mechanical strength. Application environment determines appropriate material selection.

Q: Are all substitute parts suitable for solder reflow processes?

A: All identified parts feature solder termination and UL94 V-0 flammability rating, indicating suitability for standard PCB assembly processes. Specific reflow temperature profiles and dwell times must comply with connector manufacturer specifications and solder paste requirements. Consult detailed assembly guidelines for each manufacturer variant.

Q: What compliance certifications apply to all parts in this comparison?

A: All parts carry UL94 V-0 flammability certification. The L717DD50PC is RoHS Compliant. NorComp substitutes are ROHS3 Compliant. All parts carry ECCN EAR99 and HTSUS 8536.69.4040 classifications. Applications requiring specific regulatory compliance must verify certification status against applicable standards.
