Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0705450085 is determined by strict equivalence in the following parameters:

• Pitch and Position Count: 0.100" (2.54mm) pitch with 16 positions in single row configuration
• Connector Geometry: Shrouded 4-wall header design for through-hole mounting
• Contact Configuration: Male pin contacts with gold-plated mating surfaces
• Termination Method: Solder termination capability
• Fastening: Latch holder mechanism
• Environmental Rating: UL94 V-0 flammability compliance

The TE Connectivity AMP Connectors part 1-103908-5 qualifies as a substitute based on matching these core parameters. Variations in contact material, insulation material composition, contact length specifications, and post finish composition do not preclude substitution when the primary functional and electrical parameters align.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0705450085 and TE Connectivity 1-103908-5 are active production parts meeting UL94 V-0 flammability requirements. The Molex part carries ROHS3 compliance, while the TE Connectivity substitute is RoHS non-compliant. Selection between these parts depends on regulatory requirements for the end application. The TE Connectivity part provides an extended lower operating temperature limit of -65°C compared to -40°C for the Molex part, offering broader thermal range capability. Both parts maintain identical pitch, position count, shrouding configuration, and contact finish specifications at the mating interface. The difference in contact material (phosphor bronze versus brass) and insulation material composition (polyester glass-filled versus thermoplastic) does not affect mechanical or electrical compatibility in standard through-hole solder applications.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-103908-5 directly replace the Molex 0705450085 in existing PCB designs?

A: Yes. Both connectors maintain identical 2.54mm pitch, 16-position single-row configuration, shrouded 4-wall geometry, and through-hole mounting footprint. PCB layout compatibility is maintained without design modification.

Q: What is the significance of the RoHS compliance difference?

A: The Molex 0705450085 is ROHS3 compliant, while the TE Connectivity 1-103908-5 is RoHS non-compliant. Applications subject to RoHS regulations must use the Molex part. Applications without RoHS requirements can use either part.

Q: Are the contact finishes equivalent?

A: Both parts feature gold-plated mating contacts at 30.0µin (0.76µm) thickness, ensuring equivalent electrical contact performance. Post finishes differ (tin versus tin-lead), but this does not affect solder joint quality in standard through-hole assembly.

Q: What is the temperature operating range difference?

A: The Molex part operates from -40°C to 105°C, while the TE Connectivity part operates from -65°C to 105°C. The TE Connectivity part provides 25°C additional low-temperature capability for applications requiring extended thermal range.

Q: Are there packaging or inventory considerations?

A: The Molex 0705450085 has 1078 units in stock, while the TE Connectivity 1-103908-5 has 1854 units available. Both are supplied in tube packaging.
