Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector housings is determined by strict equivalence across electrical and mechanical parameters. The primary substitution criteria for the 4-87631-0 are:

Critical Matching Parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (44)
• Pitch specification (0.100" / 2.54mm)
• Number of rows (2)
• Row spacing (0.100" / 2.54mm)
• Mounting type (Free Hanging In-Line)
• Contact termination method (Crimp)
• Fastening mechanism (Detent Lock)
• Insulation material composition (Polyamide/Nylon, Glass Filled)
• Operating temperature range (-65°C ~ 105°C)
• Series compatibility (AMPMODU Mod IV)

The substitute part 3-87631-9 meets all critical parameters and maintains full electrical and mechanical compatibility with the primary part number.

Parameter Comparison

Engineering Selection Recommendations

Both the 4-87631-0 and 3-87631-9 are Active product status components manufactured by TE Connectivity within the AMPMODU Mod IV series. The parts are electrically and mechanically equivalent across all specified parameters.

Compliance Considerations:

The 4-87631-0 carries RoHS Compliant certification, while the 3-87631-9 carries ROHS3 Compliant certification. ROHS3 represents an updated compliance standard and is fully backward compatible with RoHS requirements. Both parts meet environmental and regulatory standards for industrial and commercial applications.

Inventory and Availability:

The 3-87631-9 substitute part currently maintains higher inventory levels (933 units) compared to the primary part number (839 units), providing additional supply chain flexibility.

Selection Basis:

Component selection between these two part numbers should be based on immediate availability requirements, existing design documentation references, and procurement lead time considerations. Both parts deliver identical electrical performance and mechanical fit within the AMPMODU Mod IV connector ecosystem.

Frequently Asked Questions (FAQ)

Q: Are the 4-87631-0 and 3-87631-9 fully interchangeable in existing designs?

A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications. They share identical connector type, contact configuration, pitch, row spacing, mounting method, termination type, and operating temperature range. Direct substitution is supported without design modification.

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

A: ROHS3 represents the current iteration of the Restriction of Hazardous Substances directive. ROHS3 Compliant status indicates compliance with updated regulatory requirements and is fully compatible with RoHS Compliant applications. Both certifications restrict the same hazardous substances in electronic components.

Q: Do these connector housings include contacts?

A: No. Both the 4-87631-0 and 3-87631-9 are housing-only components. Contacts must be procured separately and installed via the crimp termination method.

Q: Can I use these parts in applications requiring temperatures below -65°C or above 105°C?

A: No. Both parts are rated for the operating temperature range of -65°C to 105°C. Applications requiring operation outside this range require alternative component selection.

Q: Are there any differences in the insulation material between these two part numbers?

A: No. Both parts use identical insulation material composition: Polyamide (PA), Nylon, Glass Filled. Material properties, thermal characteristics, and chemical resistance are equivalent.

Q: What is the significance of MSL Level 1 (Unlimited)?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life under standard storage conditions. No special moisture control measures or baking procedures are required prior to assembly.

Q: Can these receptacle housings be mated with connector plugs from other manufacturers?

A: Compatibility depends on the plug connector specifications. Both housings are designed for the AMPMODU Mod IV series and accept mating plugs that conform to the 44-position, 2-row, 0.100" pitch configuration of this series. Verification of specific plug part numbers is required for cross-manufacturer compatibility.

Q: What mounting applications are supported by the Free Hanging (In-Line) configuration?

A: Free Hanging (In-Line) mounting indicates these housings are designed for cable or harness assembly applications where the connector is suspended in-line without panel or PCB mounting. The housing provides strain relief and detent lock engagement with mating plug connectors.
