Amphenol ICC 865637SLT D-Sub Receptacle 37-Position Connector

Part Overview

The 865637SLT is a D-Sub receptacle housing designed for female contacts in a 37-position configuration. This connector is manufactured by Amphenol ICC (FCI) and serves as a panel-mount solution for signal applications requiring a 2-row D-shaped connector layout. The part is currently active in production with 924 units in stock. Finding equivalent substitute parts is necessary to ensure supply chain flexibility, optimize procurement timelines, and maintain design compatibility across manufacturing batches.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 865637SLT is determined by strict equivalence across the following critical parameters:

• Connector Style: D-Sub
• Connector Type: Receptacle for Female Contacts
• Number of Positions: 37
• Number of Rows: 2
• Shell Size, Connector Layout: 4 (DC, C)
• Mounting Type: Panel Mount
• Shell Material, Finish: Steel, Tin/Zinc Plated
• Operating Temperature Range: -55°C to 125°C
• Mating Cycles: 200
• Dielectric Material: Thermoplastic
• Contact Type: Signal
• Flange Feature: Housing/Shell (Unthreaded)
• Series: 8656

The substitute part 865637SLTLF matches all critical parameters and is therefore a direct functional equivalent. Differences in RoHS compliance status and color designation do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the 865637SLT and 865637SLTLF are active production parts from Amphenol ICC within the 8656 series. Selection between these parts should be based on regulatory and compliance requirements:

The 865637SLTLF is RoHS Compliant and REACH Affected, making it the appropriate choice for applications subject to European Union environmental regulations or customer specifications requiring RoHS compliance.

The 865637SLT is RoHS non-compliant and may be selected for applications where such compliance is not mandated or where legacy system compatibility is required.

Both parts are electrically and mechanically equivalent and will function identically in D-Sub 37-position receptacle applications. The choice between them is determined by regulatory context and supply availability rather than technical performance.

Frequently Asked Questions (FAQ)

Q: Can 865637SLTLF be used as a direct replacement for 865637SLT?

A: Yes. Both parts are functionally equivalent across all electrical and mechanical parameters. The 865637SLTLF differs only in RoHS compliance status and color specification. Selection depends on regulatory requirements and application constraints.

Q: What is the significance of the RoHS compliance difference?

A: RoHS compliance indicates adherence to the Restriction of Hazardous Substances Directive. The 865637SLTLF meets these restrictions; the 865637SLT does not. Applications subject to EU regulations or customer RoHS requirements must use the 865637SLTLF variant.

Q: Are the contact specifications identical between these parts?

A: Both parts are receptacles for female contacts and do not include contacts in the package. Contact specifications are determined by the mating plug connector and are independent of the housing selection.

Q: Does the color difference affect connector performance?

A: No. Color is a visual identifier only and does not affect electrical or mechanical function. Both parts use identical shell material and finish specifications.

Q: What is the mating cycle rating and what does it indicate?

A: Both parts are rated for 200 mating cycles, indicating the number of times the connector can be mated and unmated under normal operating conditions before performance degradation occurs.

Q: Are these connectors suitable for high-temperature applications?

A: Both parts operate across the temperature range of -55°C to 125°C. Applications requiring operation outside this range require alternative connector designs.
