Amphenol ICC 8656O25SLT D-Sub Connector Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 8656O25SLT is a D-Sub receptacle housing designed for female contacts in 25-position configurations. This connector is classified as an active product with established market availability. The 8656O25SLT is supplied in bulk packaging and serves as a panel-mount solution for D-Sub applications requiring standard shell size 3 (DB, B) layout.

Identifying equivalent and substitute parts becomes necessary when bulk packaging is unavailable, when RoHS compliance is required for specific applications, or when alternative packaging formats better suit production workflows.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 8656O25SLT is determined by the following critical parameters that must remain constant:

• Connector Type: Receptacle for Female Contacts
• Number of Positions: 25
• Shell Size, Connector Layout: 3 (DB, B)
• Mounting Type: Panel Mount
• Shell Material, Finish: Steel, Tin/Zinc Plated
• Operating Temperature Range: -55°C ~ 125°C
• Mating Cycles: 200
• Dielectric Material: Thermoplastic
• Flange Feature: Housing/Shell (4-40)
• Contact Type: Signal
• Moisture Sensitivity Level: 1 (Unlimited)

The 8656O25SLTLF qualifies as a direct substitute because it maintains all critical electrical and mechanical parameters while differing only in packaging format (tray versus bulk) and compliance certifications.

Engineering Selection Recommendations

The 8656O25SLTLF serves as a direct functional equivalent to the 8656O25SLT for all D-Sub 25-position receptacle housing applications. Selection between these parts should be based on the following criteria:

Choose 8656O25SLT when:

• Bulk packaging format is required for high-volume production runs
• RoHS compliance is not a regulatory requirement for the end application

Choose 8656O25SLTLF when:

• RoHS compliance is mandated by application requirements or regional regulations
• Tray packaging format aligns with assembly and logistics workflows
• REACH compliance documentation is required

Both parts maintain identical electrical performance, mechanical compatibility, and environmental operating specifications. The choice between them is driven by packaging preference and regulatory compliance needs rather than functional capability.

Frequently Asked Questions (FAQ)

Q: Can the 8656O25SLTLF be used as a direct replacement for the 8656O25SLT in existing designs?

A: Yes. The 8656O25SLTLF is electrically and mechanically identical to the 8656O25SLT. All connector specifications, mating cycles, operating temperature range, and physical dimensions remain unchanged. The only differences are packaging format and RoHS compliance status.

Q: What is the difference between bulk and tray packaging for these D-Sub connectors?

A: Bulk packaging supplies components without individual protective packaging, suitable for high-volume automated assembly. Tray packaging provides organized compartmentalization, offering improved handling protection and easier inventory management for moderate-volume applications.

Q: Does the RoHS compliance difference affect connector performance?

A: No. RoHS compliance relates to material composition and manufacturing processes, not electrical or mechanical performance. Both parts operate identically within the specified -55°C to 125°C temperature range and support 200 mating cycles.

Q: Are contacts included with either part number?

A: No. Both the 8656O25SLT and 8656O25SLTLF are housing-only components. Female contacts must be sourced separately and crimped into the housing.

Q: What is the significance of the 4-40 flange feature?

A: The 4-40 flange feature indicates the mounting hole specification. This standardized specification ensures consistent panel-mount installation across both part numbers.

Q: Can these connectors be used in applications requiring REACH compliance?

A: The 8656O25SLTLF is documented as REACH Unaffected. The 8656O25SLT does not specify REACH status. For applications with explicit REACH compliance requirements, the 8656O25SLTLF is the appropriate selection.
