Key Parameters

Substitute Part Grouping Explanation

Substitution of the L717DFC37P is determined by the following core parameters that must remain constant across all equivalent parts:

Fixed Parameters (Must Match):

• Connector Style: D-Sub
• Connector Type: Plug, Male Pins
• Number of Positions: 37
• Number of Rows: 2
• Shell Size, Connector Layout: 4 (DC, C)
• Termination: Solder Cup
• Shell Material, Finish: Steel, Tin Plated
• Voltage Rating: 300V
• Operating Temperature: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: RoHS Compliant

Variable Parameters (Allowed to Differ):

• Mounting Type: Panel Mount (main part) vs. Free Hanging (In-Line) (substitute parts)
• Current Rating: 7.5A (main part) vs. 5A per Contact (substitute parts)
• Contact Finish Thickness: 20.0µin (main part) vs. Flash or 30.0µin (substitute parts)
• Contact Material: Brass (main part) vs. Copper Alloy (substitute parts)
• Features: Grounding Indents (main part) vs. Grounding Indents and/or Shielded (substitute parts)
• Color: Black (main part) vs. Natural (substitute parts)
• Packaging: Bag (main part) vs. Tray (substitute parts)

The substitute parts DC37P064TXLF, DC37P064HTXLF, DC37P065TXLF, and DC37P065HTXLF are functionally equivalent for applications where free hanging (in-line) mounting is acceptable and current requirements do not exceed 5A per contact.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and full RoHS compliance, ensuring regulatory and compliance continuity with the L717DFC37P.

DC37P064TXLF and DC37P064HTXLF Selection: These parts are suitable for applications requiring free hanging (in-line) mounting where panel mount configuration is not required. Both parts feature flash gold contact finish and are available in high inventory quantities (1139 and 1392 units respectively). DC37P064HTXLF includes shielded features. Current rating of 5A per contact is applicable for circuits not exceeding this threshold.

DC37P065TXLF and DC37P065HTXLF Selection: These parts provide enhanced contact durability through GXT™ gold finish technology with 30.0µin thickness, exceeding the main part specification of 20.0µin. Both parts are suitable for free hanging (in-line) mounting. DC37P065HTXLF includes shielded features. Current rating of 5A per contact applies. These parts are appropriate for applications requiring extended contact life and improved corrosion resistance.

Mounting Type Consideration: The primary distinction between the main part and all substitute parts is mounting configuration. The L717DFC37P is panel mount, while all substitutes are free hanging (in-line). Selection of substitute parts requires confirmation that the application accommodates in-line mounting.

Current Rating Consideration: The L717DFC37P supports 7.5A current rating. All substitute parts are rated at 5A per contact. Applications requiring current levels between 5A and 7.5A per contact must retain the L717DFC37P.

Frequently Asked Questions (FAQ)

Q: Can DC37P064TXLF, DC37P064HTXLF, DC37P065TXLF, or DC37P065HTXLF be used as direct replacements for L717DFC37P?

A: These parts are functionally equivalent for signal transmission and electrical performance within the 5A per contact current limit. However, they are not direct mechanical replacements due to mounting type differences. L717DFC37P is panel mount, while all substitute parts are free hanging (in-line). Mechanical integration into the application must be evaluated.

Q: What is the difference between DC37P064 and DC37P065 series?

A: The primary difference is contact finish thickness and technology. DC37P064 series features flash gold finish, while DC37P065 series features GXT™ gold finish at 30.0µin thickness. DC37P065 provides enhanced contact durability and corrosion resistance. Both series maintain identical electrical ratings and connector geometry.

Q: What is the significance of the "H" designation in DC37P064HTXLF and DC37P065HTXLF?

A: The "H" designation indicates shielded connector features. DC37P064HTXLF and DC37P065HTXLF include shielding, while DC37P064TXLF and DC37P065TXLF do not. Shielded variants are appropriate for applications requiring electromagnetic interference (EMI) mitigation.

Q: Are all substitute parts RoHS compliant?

A: Yes. DC37P064TXLF, DC37P064HTXLF, DC37P065TXLF, and DC37P065HTXLF are all RoHS compliant and maintain regulatory equivalence with L717DFC37P.

Q: What is the current rating limitation for substitute parts?

A: All substitute parts are rated at 5A per contact. Applications requiring current levels exceeding 5A per contact must use L717DFC37P, which is rated at 7.5A.

Q: Can substitute parts be used in high-temperature applications?

A: Yes. All substitute parts maintain the same operating temperature range as L717DFC37P: -55°C to 125°C. Temperature performance is equivalent across all parts.

Q: What packaging differences exist between the main part and substitutes?

A: L717DFC37P is supplied in bag packaging. All substitute parts are supplied in tray packaging. This affects handling, storage, and component management but does not impact electrical or mechanical performance.

Q: Are substitute parts available in the same color as L717DFC37P?

A: No. L717DFC37P is black, while all substitute parts are natural color. Visual identification and aesthetic considerations may differ, but functional performance is equivalent.
