Engineering Selection Recommendations

All five substitute parts are direct functional equivalents to the 0347960401 and are suitable for replacement in applications requiring 4-position rectangular connector housings at 4.60mm pitch. Selection among substitutes should be based on the following criteria:

Product Status: All substitute parts maintain active product status, ensuring long-term availability and supply chain continuity compared to the discontinued original part.

Compliance & Certifications: All substitutes maintain ROHS3 compliance and MSL 1 rating. Parts 0334710463 and 0334710465 are marked as REACH Affected, while 0334710402, 0334710407, and 0334710464 are REACH Unaffected. Selection should account for REACH compliance requirements in the target application region.

Operating Temperature: Substitute parts provide extended operating temperature range (-40°C ~ 125°C) compared to the original part (-40°C ~ 105°C), offering improved thermal performance for high-temperature applications.

Material Composition: The original part uses PBT insulation material, while all substitutes use Polyester. Both materials maintain equivalent electrical and mechanical properties for this connector class and are suitable for direct substitution.

Inventory Levels: Part 0334710402 offers the highest inventory availability (2461 Pcs), followed by 0334710463 (1676 Pcs) and 0334710465 (1617 Pcs), supporting immediate procurement requirements.

Frequently Asked Questions (FAQ)

Q: Are all substitute parts mechanically compatible with the original 0347960401?

A: Yes. All substitute parts maintain identical mechanical specifications: 4-position configuration, 0.138" (4.60mm) pitch, free-hanging in-line mounting, crimp termination, and latch holder fastening. Direct mechanical interchangeability is confirmed.

Q: What is the difference between the original part and substitutes in terms of material?

A: The original 0347960401 uses Polybutylene Terephthalate (PBT) insulation, while all substitute parts use Polyester insulation. Both materials provide equivalent electrical performance and mechanical durability for rectangular connector housings in this application class.

Q: Do the substitute parts support the same contact types?

A: Yes. All substitute parts accommodate female socket contacts with crimp termination, maintaining full compatibility with existing contact inventories and assembly processes.

Q: What is the significance of the extended operating temperature range in substitute parts?

A: Substitute parts support -40°C ~ 125°C operation compared to the original -40°C ~ 105°C range. This extended range provides additional thermal margin for applications operating at elevated temperatures, though both ranges are suitable for standard industrial environments.

Q: Are there any REACH compliance differences among the substitute parts?

A: Parts 0334710463 and 0334710465 are marked as REACH Affected, while 0334710402, 0334710407, and 0334710464 are REACH Unaffected. Selection should align with regional regulatory requirements for the target application.

Q: Can I mix substitute parts in the same assembly?

A: Yes. All substitute parts are electrically and mechanically equivalent and can be used interchangeably within the same assembly or system without functional impact.

Q: What packaging format is available for the substitute parts?

A: All substitute parts are supplied in Bulk packaging, suitable for production assembly and component inventory management.
