Substitute Part Grouping Explanation

Substitution of the 3-87589-8 with the 5-103168-7 is based on strict equivalence of the following critical parameters:

Electrical Compatibility Parameters:

• Contact Type: Male Pin (identical)
• Number of Positions: 18 (identical)
• Number of Rows: 2 (identical)
• Pitch - Mating: 0.100" (2.54mm) (identical)
• Row Spacing - Mating: 0.100" (2.54mm) (identical)
• Current Rating: 3A (identical)
• Operating Temperature Range: -65°C ~ 105°C (identical)

Mechanical Compatibility Parameters:

• Connector Type: Header (identical)
• Mounting Type: Through Hole (identical)
• Termination: Solder (identical)
• Shrouding: Shrouded - 4 Wall (identical)
• Contact Length - Mating: 0.318" (8.08mm) (identical)
• Contact Length - Post: 0.125" (3.18mm) (identical)
• Overall Contact Length: 0.533" (13.55mm) (identical)
• Insulation Height: 0.440" (11.18mm) (identical)
• Contact Shape: Square (identical)
• Material Flammability Rating: UL94 V-0 (identical)

Series Designation:

• Series: AMPMODU Mod II (identical)

The substitute part 5-103168-7 maintains full dimensional and functional compatibility with the original 3-87589-8 connector header.

Parameter Comparison

Engineering Selection Recommendations

The 5-103168-7 serves as a direct functional substitute for the obsolete 3-87589-8. Both components are manufactured by TE Connectivity within the AMPMODU Mod II series and maintain identical electrical and mechanical specifications across all critical parameters including connector type, contact configuration, pitch spacing, mounting method, and operating temperature range.

The primary distinction between the two parts is product status: the 3-87589-8 is obsolete while the 5-103168-7 is active. The substitute part is currently in production and available in higher inventory quantities (1923 pieces versus 689 pieces for the main part).

Secondary differences exist in contact finish specifications and insulation material composition. The 5-103168-7 features gold plating on mating contacts with reduced thickness (30.0µin versus 100.0µin) and thermoplastic insulation material, compared to tin plating and glass-filled polyamide in the original part. These material variations do not affect functional compatibility for standard through-hole solder applications within the specified operating temperature range.

The substitute part carries RoHS Compliance certification and defined REACH status, providing enhanced regulatory documentation compared to the vendor-undefined status of the original part. Both components share identical ECCN and HTSUS classifications.

Frequently Asked Questions (FAQ)

Q: Can the 5-103168-7 be used as a direct replacement for the 3-87589-8 in existing designs?

A: Yes. The 5-103168-7 maintains identical electrical and mechanical specifications across all critical parameters including connector type, position count, pitch spacing, mounting method, and operating temperature range. The components are functionally interchangeable for through-hole solder applications.

Q: What are the differences between the two parts?

A: The primary differences are product status (obsolete versus active), contact finish composition (tin versus gold on mating surfaces), contact finish thickness (100.0µin versus 30.0µin on mating surfaces), and insulation material (glass-filled polyamide versus thermoplastic). These differences do not affect functional compatibility.

Q: Does the gold plating on the 5-103168-7 affect compatibility?

A: No. Gold plating on the mating contacts of the 5-103168-7 is compatible with standard connector receptacles designed for the 0.100" (2.54mm) pitch AMPMODU Mod II series. The contact material remains phosphor bronze in both parts.

Q: What is the packaging difference between these parts?

A: The 3-87589-8 packaging is not specified in the provided data. The 5-103168-7 is supplied in Tray packaging.

Q: Are there any compliance or regulatory differences?

A: The 5-103168-7 carries RoHS Compliance certification and defined REACH Unaffected status. The 3-87589-8 has vendor-undefined status for both certifications. Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: What is the current rating for both parts?

A: Both the 3-87589-8 and 5-103168-7 are rated for 3A continuous current.

Q: Are the operating temperature ranges identical?

A: Yes. Both parts operate across the identical temperature range of -65°C to 105°C.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture control requirements.
