Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0705510044 and TE Connectivity 5-103673-9 are active-status products with full RoHS compliance and UL94 V-0 flammability certification. The TE Connectivity part provides an extended operating temperature range (-65°C to 105°C versus -40°C to 105°C), offering additional thermal margin for demanding applications. Both parts maintain identical pitch, position count, mounting configuration, and contact finish specifications. Selection between these parts should be based on application-specific temperature requirements, supply chain availability, and design validation protocols established for your organization.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5-103673-9 be used as a direct replacement for the Molex 0705510044?

A: Yes, within the specified electrical and mechanical parameters. Both parts share identical pitch (0.100"), position count (10), mounting type (through-hole right-angle), shrouding (4-wall), and contact finish (gold). Minor dimensional variations in contact length and insulation height fall within acceptable tolerance ranges for this connector category.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Contact material composition (Phosphor Bronze vs. Brass), (2) Insulation material (Polyester, Glass Filled vs. Thermoplastic), (3) Operating temperature range (TE part rated to -65°C), (4) Contact finish thickness on posts (Molex 74.8µin vs. TE 100.0µin), and (5) Packaging format (Molex Bulk vs. TE Tube).

Q: Are there any compliance or certification concerns with substitution?

A: No. Both parts carry UL94 V-0 flammability ratings, RoHS compliance, and identical ECCN/HTSUS classifications. Moisture sensitivity levels are equivalent at MSL 1 (Unlimited).

Q: Does packaging format affect compatibility?

A: Packaging format (Bulk vs. Tube) does not affect electrical or mechanical compatibility. It impacts only handling, storage, and logistics considerations.

Q: What should be verified before implementing this substitution in production?

A: Verify that the extended temperature range of the TE part (-65°C minimum) aligns with your application requirements, and confirm that minor dimensional variations in contact length and insulation height are acceptable for your specific PCB layout and mating connector design.
