Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FCE17C37PB650 are qualified based on the following critical parameters that determine functional interchangeability:

Core Compatibility Criteria:

• Connector Type: D-Sub Plug with Male Pins
• Number of Positions: 37
• Number of Rows: 2
• Shell Size, Connector Layout: 4 (DC, C)
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Current Rating: 5A per Contact
• Contact Type: Signal
• Material Flammability Rating: UL94 V-0
• RoHS Compliance: Required

All three substitute parts (D37P13A4GL00LF, D37P13A4GV00LF, D37P13A4GX00LF) meet these core criteria. Variations exist in shell material finish (Tin-Nickel Plated vs. Tin Plated), contact material (Brass vs. Phosphor Bronze), flange feature design, and operating temperature range. These variations do not prevent functional substitution when the application requirements align with the specified parameters of each substitute part.

Parameter Comparison

Engineering Selection Recommendations

D37P13A4GL00LF Selection Criteria: This substitute part is suitable when the application requires extended operating temperature range (-55°C to 125°C) compared to the FCE17C37PB650 (-40°C to 85°C), and when 300V voltage rating specification is required. The part maintains RoHS Compliance and MSL 1 rating. The Housing/Shell (M3) flange feature matches the main part configuration. Backset spacing difference of 0.004" (0.11mm) is within typical PCB layout tolerances for D-Sub connectors.

D37P13A4GV00LF Selection Criteria: This substitute is applicable when the application requires mating-side female screwlock (4-40) flange feature for enhanced mechanical retention. Extended operating temperature range (-55°C to 125°C) and 300V voltage rating are provided. RoHS Compliance and MSL 1 rating are maintained. This configuration is suitable for applications requiring positive mating force control.

D37P13A4GX00LF Selection Criteria: This substitute meets ROHS3 Compliance requirement (versus RoHS Compliant for the main part) and is suitable for applications with REACH Affected material declarations. Housing/Shell (4-40) flange feature provides alternative mounting configuration. Extended operating temperature range (-55°C to 125°C) and 300V voltage rating are available. This part is appropriate for applications with stricter regulatory compliance requirements.

All substitute parts share core electrical and mechanical compatibility with the FCE17C37PB650 based on connector type, position count, shell size, mounting configuration, and current rating specifications.

Frequently Asked Questions (FAQ)

Q1: Can D37P13A4GL00LF, D37P13A4GV00LF, and D37P13A4GX00LF be used interchangeably with FCE17C37PB650?

A: These parts share identical core specifications for connector type (D-Sub Plug, Male Pins), position count (37), row configuration (2), shell size (4 DC, C), mounting type (Through Hole, Right Angle), termination method (Solder), current rating (5A per Contact), and flammability rating (UL94 V-0). Functional substitution is supported when application requirements align with each part's specific parameters. Differences in flange feature design, contact material, and operating temperature range must be evaluated against application requirements.

Q2: What are the key differences between the main part and substitute parts?

A: The FCE17C37PB650 features Phosphor Bronze contacts with 15.0µin gold plating and operates from -40°C to 85°C. Substitute parts use Brass contacts with flash gold plating and operate from -55°C to 125°C. Shell material finish differs (Tin Plated vs. Tin-Nickel Plated). Flange features vary: FCE17C37PB650 and D37P13A4GL00LF use Housing/Shell (M3), D37P13A4GV00LF uses Mating Side Female Screwlock (4-40), and D37P13A4GX00LF uses Housing/Shell (4-40). Substitute parts specify 300V voltage rating; the main part does not specify voltage rating.

Q3: Are there backset spacing compatibility concerns?

A: The FCE17C37PB650 specifies 0.405" (10.29mm) backset spacing, while all substitute parts specify 0.409" (10.40mm). This 0.004" (0.11mm) difference is within standard PCB layout tolerances for D-Sub connectors and does not prevent functional substitution. PCB design verification is recommended to confirm accommodation of this minor spacing variation.

Q4: What is the significance of contact material differences (Phosphor Bronze vs. Brass)?

A: Both Phosphor Bronze and Brass are acceptable contact materials for D-Sub signal connectors. The material difference does not affect electrical performance for standard signal applications. Contact finish (gold plating) provides the primary corrosion resistance and electrical interface characteristics. Material selection should be verified against specific application requirements and environmental conditions.

Q5: How do operating temperature ranges affect part selection?

A: The FCE17C37PB650 operates from -40°C to 85°C. All substitute parts operate from -55°C to 125°C, providing extended temperature capability. If the application operates within the FCE17C37PB650 temperature range, either the main part or any substitute part is suitable. If the application requires operation below -40°C or above 85°C, substitute parts must be selected.

Q6: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: RoHS Compliant indicates compliance with the original Restriction of Hazardous Substances Directive. ROHS3 Compliant indicates compliance with the updated RoHS 3 Directive (2011/65/EU as amended by 2015/863/EU), which includes additional restricted substances. D37P13A4GX00LF with ROHS3 Compliant status is suitable for applications with stricter regulatory requirements.

Q7: What does REACH Affected status indicate for D37P13A4GX00LF?

A: REACH Affected status indicates that the part contains substances subject to the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) regulation. This designation requires documentation and compliance verification for applications in regulated industries. D37P13A4GL00LF and D37P13A4GV00LF are listed as REACH Unaffected.

Q8: How do flange feature differences impact mechanical installation?

A: FCE17C37PB650 and D37P13A4GL00LF use Housing/Shell (M3) flange with M3 mounting holes. D37P13A4GV00LF features Mating Side Female Screwlock (4-40) for positive mating retention. D37P13A4GX00LF uses Housing/Shell (4-40) with 4-40 mounting holes. Flange feature selection depends on the mating connector type and mechanical retention requirements of the application. PCB mounting hole pattern must accommodate the selected flange configuration.

Q9: Are packaging differences significant for component procurement?

A: The FCE17C37PB650 packaging is not specified in available documentation. All substitute parts are supplied in Tray packaging. Packaging format may affect handling, storage, and automated assembly processes. Procurement and manufacturing teams should verify packaging compatibility with existing component handling and assembly equipment.

Q10: What inventory considerations apply to these substitute parts?

A: Current inventory levels are: FCE17C37PB650 (1114 Pcs), D37P13A4GL00LF (1148 Pcs), D37P13A4GV00LF (1163 Pcs), and D37P13A4GX00LF (984 Pcs). All parts are listed as New Original In Stock. Inventory levels may change; verification with supplier is recommended for long-term procurement planning.
