Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 173853-4 are identified based on strict parametric equivalence within the Multi-Lock rectangular connector series. The following parameters must remain constant for functional substitution:

• Connector Type: Plug
• Contact Type: Female Socket
• Number of Positions: 18
• Number of Rows: 2
• Row Spacing: 0.232" (5.90mm)
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Fastening Type: Latch Lock
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Variations in color and product status are permitted where all electrical and mechanical parameters remain identical. The following parts meet these substitution criteria:

1. 173853-1 - White housing variant, active product status
2. 176118-5 - Blue housing variant, last time buy status

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity 173853-1

The 173853-1 is the recommended substitute for the obsolete 173853-4. This part maintains identical electrical and mechanical specifications while offering active product status with current manufacturing support. The 173853-1 is supplied in tray packaging and carries REACH Unaffected compliance status, providing superior supply chain continuity compared to the obsolete main part.

Secondary Substitute: TE Connectivity 176118-5

The 176118-5 provides functional equivalence with all critical parameters matching the 173853-4. However, this part carries last time buy status, indicating limited future availability. Selection of this part should be restricted to applications where existing inventory management or design documentation specifically requires this variant.

Both substitute parts maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring compatibility with existing environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can 173853-1 be used as a direct replacement for 173853-4 in existing assemblies?

A: Yes. The 173853-1 maintains identical connector type, position count, row spacing, mounting configuration, and contact termination method. The housing color difference (white versus green) does not affect electrical or mechanical function.

Q: What is the significance of the product status difference between these parts?

A: The 173853-4 is obsolete and no longer manufactured. The 173853-1 is active, ensuring continued availability for new production and design revisions. The 176118-5 is last time buy, indicating a defined end-of-life date with limited remaining inventory.

Q: Are the contacts compatible across all three part numbers?

A: All three parts use identical crimp contact termination and 18-position configuration. Contacts specified for the 173853-4 are compatible with both 173853-1 and 176118-5 housings.

Q: Does the insulation material specification affect substitution?

A: The 173853-1 specifies Polybutylene Terephthalate (PBT) insulation material with operating temperature range -30°C to 105°C. This material and temperature range are standard for Multi-Lock series housings and do not restrict substitution.

Q: What packaging differences exist between substitute parts?

A: The 173853-4 packaging is not specified. The 173853-1 is supplied in tray packaging. The 176118-5 packaging is not specified. Packaging differences do not affect component function and are determined by procurement requirements.

Q: Are all three parts compliant with current regulatory standards?

A: Yes. All three parts are ROHS3 compliant with EAR99 export classification. The 173853-1 carries REACH Unaffected status, while the 173853-4 and 176118-5 carry vendor undefined REACH status.
