Engineering Selection Recommendations

Both substitute parts 1-87631-9 and 2-87631-0 are Active products with full RoHS compliance and EAR99 export classification, matching the regulatory status of the primary part 1-281839-2. All three parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture precautions are required during storage or handling.

The primary distinction between substitute options lies in insulation material composition and operating temperature range. Part 1-87631-9 utilizes Thermoplastic insulation with an operating range of -65°C to 105°C. Part 2-87631-0 employs Polyamide (PA) Nylon Glass Filled insulation, also rated -65°C to 105°C. The original part 1-281839-2 specifies Polybutylene Terephthalate (PBT) Glass Filled insulation with a wider operating range of -55°C to 125°C.

Selection between the primary part and substitutes should be based on application-specific temperature requirements. Applications requiring operation above 105°C necessitate the original 1-281839-2. For applications within the -65°C to 105°C range, either substitute part provides equivalent functional performance. Part 2-87631-0 offers the highest current inventory availability at 2320 units.

Frequently Asked Questions (FAQ)

Q: Can 1-87631-9 and 2-87631-0 be used interchangeably with 1-281839-2?

A: Both substitute parts satisfy all critical parametric requirements for mechanical and electrical compatibility. Selection depends on application temperature range. The original part 1-281839-2 supports operation to 125°C, while both substitutes are rated to 105°C maximum. Within the -65°C to 105°C range, substitutes provide equivalent performance.

Q: What is the significance of the different insulation materials?

A: The original part uses Polybutylene Terephthalate (PBT) Glass Filled insulation. Substitute 1-87631-9 uses Thermoplastic material, and substitute 2-87631-0 uses Polyamide (PA) Nylon Glass Filled material. These material differences result in the operating temperature range variations noted. Material selection should align with application thermal requirements.

Q: Are there any compliance or regulatory differences between these parts?

A: All three parts carry identical export classification (EAR99) and tariff codes (8538.90.6000). The original part is ROHS3 Compliant, while both substitutes are RoHS Compliant. All parts carry Moisture Sensitivity Level 1 (Unlimited), requiring no special moisture handling procedures.

Q: Do these parts include contacts?

A: No. All three part numbers specify "Contacts Not Included" in their product documentation. Contacts must be sourced separately and crimped into the housing according to TE Connectivity specifications.

Q: What is the difference between the HE13/HE14 series and AMPMODU Mod IV series?

A: These represent different product series from TE Connectivity. The original part belongs to the HE13/HE14 series, while both substitutes belong to the AMPMODU Mod IV series. Despite series differences, all parts maintain identical mechanical pitch, row configuration, and mounting characteristics, enabling direct substitution within the specified temperature operating range.

Q: Which substitute part should be selected for maximum inventory availability?

A: Part 2-87631-0 provides the highest current stock level at 2320 units, compared to 1393 units for 1-87631-9 and 828 units for the original 1-281839-2.
