Key Parameters

Substitute Part Grouping Explanation

Substitute part 316517-2 is classified as an equivalent alternative to the main part 316517-3 based on the following critical parameters that determine substitution eligibility:

Matching Parameters (Substitution Basis):

• Connector type, configuration, and form factor (Header, 20-position, 2-row)
• Pitch specifications (0.200" mating pitch and row spacing)
• Mounting methodology (Through Hole)
• Shrouding design (Shrouded - 4 Wall)
• Electrical ratings (600V voltage rating)
• Temperature operating range (-55°C ~ 105°C)
• Fastening mechanism (Detent Lock)
• Termination method (Solder)
• Contact material and shape (Copper Alloy, Rectangular)
• Insulation material and flammability rating (Thermoplastic, Polyester, Glass Filled; UL94 V-0)
• Series designation (Dynamic D-3500)

Distinguishing Parameter:

• Contact Finish Thickness - Mating: 316517-3 specifies 30.0µin (0.76µm) gold plating; 316517-2 specifies 15.0µin (0.38µm) gold plating

Both parts maintain full compatibility for standard applications where the contact finish thickness differential does not impact performance requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the 316517-3 and 316517-2 are active products within the TE Connectivity Dynamic D-3500 series and maintain full compliance with RoHS standards. The 316517-3 carries RoHS Compliant certification, while the 316517-2 carries ROHS3 Compliant certification, indicating enhanced regulatory alignment for the substitute part.

The primary technical distinction between these parts is the contact finish thickness on the mating surface. The 316517-3 provides 30.0µin (0.76µm) gold plating, while the 316517-2 provides 15.0µin (0.38µm) gold plating. Both thicknesses remain within industry-standard specifications for rectangular connector headers and support equivalent electrical performance and contact reliability for general purpose and industrial applications.

Selection between these parts should be based on inventory availability, lead time requirements, and specific application constraints. Both parts are suitable for direct substitution in applications where the contact finish thickness differential does not impose additional performance or durability requirements.

Frequently Asked Questions (FAQ)

Q: Are the 316517-3 and 316517-2 fully interchangeable?

A: Yes, these parts are fully interchangeable for standard applications. Both connectors share identical mechanical dimensions, electrical ratings, mounting configurations, and operational characteristics. The only difference is the gold plating thickness on the mating contacts.

Q: What is the significance of the contact finish thickness difference?

A: Contact finish thickness affects long-term wear resistance and corrosion protection. The 316517-3 with 30.0µin (0.76µm) plating provides enhanced durability for high-cycle mating applications or harsh environments. The 316517-2 with 15.0µin (0.38µm) plating is suitable for standard industrial and general purpose applications with typical mating cycles.

Q: Can I use 316517-2 in place of 316517-3 in my existing design?

A: Yes, the 316517-2 can be used as a direct substitute for the 316517-3 without design modifications. Both parts maintain the same form factor, pitch, row spacing, voltage rating, temperature range, and mounting methodology.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: Both certifications indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents a more recent version of the standard with updated substance restrictions. The 316517-2 with ROHS3 Compliant status meets current regulatory requirements.

Q: Are both parts suitable for industrial applications?

A: Yes, both the 316517-3 and 316517-2 are rated for general purpose and industrial applications. They operate across the temperature range of -55°C to 105°C and maintain a 600V voltage rating suitable for industrial control and interconnection systems.

Q: What is the through-hole post length for these connectors?

A: Both parts feature a contact length post of 0.150" (3.81mm), ensuring consistent solder joint formation and mechanical stability when mounted on printed circuit boards.

Q: Do these connectors require any special handling or storage?

A: Both parts carry a Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no special moisture control requirements during storage or handling.
