Substitute Part Grouping Explanation

Substitution eligibility for the HTSW-103-14-L-S is determined by strict alignment of the following critical parameters:

Connector type (Header with male pin contact)
Pitch specification (0.100" / 2.54mm)
Position count (3 positions, single row)

Contact finish on mating surface (Gold plating)
Insulation material compatibility (LCP or equivalent polymeric material)
Flammability rating (UL94 V-0)
RoHS compliance status

The identified substitute parts meet these core electrical and mechanical criteria, enabling direct replacement in applications where the HTSW-103-14-L-S is specified.

Engineering Selection Recommendations

All three connectors maintain Active product status and satisfy UL94 V-0 flammability requirements. The HTSW-103-14-L-S and 929705-01-03-EU share identical insulation height (0.100") and contact post length (0.110"), providing the closest mechanical alignment. The 5-146276-3 exhibits a reduced insulation height (0.090") and extended contact post length (0.125"), which may affect board layout compatibility in space-constrained applications.

Operating temperature ranges differ across the three options. The HTSW-103-14-L-S supports the widest range (-55°C ~ 125°C), while the 5-146276-3 extends the lower temperature limit to -65°C. The 929705-01-03-EU operates within -40°C ~ 105°C. Selection should align with the application's thermal requirements.

All parts are RoHS compliant. The HTSW-103-14-L-S and 5-146276-3 carry ROHS3 designation, while the 929705-01-03-EU is RoHS compliant without specific revision notation.

Frequently Asked Questions (FAQ)

Q: What determines if a connector can substitute for the HTSW-103-14-L-S?

A: Substitution requires matching pitch (0.100" / 2.54mm), position count (3), row configuration (single row), mounting method (through hole), termination type (solder), contact type (male pin), and mating contact finish (gold). All identified substitutes meet these criteria.

Q: Are there mechanical differences I should consider?

A: Yes. The 5-146276-3 has a lower insulation height (0.090" vs. 0.100") and longer contact post (0.125" vs. 0.110"). These differences may impact PCB footprint compatibility and mating depth. The 929705-01-03-EU matches the original dimensions more closely.

Q: What is the temperature operating range difference?

A: The HTSW-103-14-L-S operates from -55°C to 125°C. The 5-146276-3 extends to -65°C at the lower end but limits to 105°C maximum. The 929705-01-03-EU operates within -40°C to 105°C. Select based on your application's thermal environment.

Q: Are all parts RoHS compliant?

A: Yes. The HTSW-103-14-L-S and 5-146276-3 are ROHS3 compliant. The 929705-01-03-EU is RoHS compliant. All meet environmental compliance requirements.

Q: What is the difference between the insulation materials?

A: The HTSW-103-14-L-S and 5-146276-3 use Liquid Crystal Polymer (LCP). The 929705-01-03-EU uses Polycyclohexylenedimethylene Terephthalate (PCT). Both materials provide UL94 V-0 flammability ratings and are suitable for through-hole solder applications.

Q: Can I use these connectors interchangeably on the same PCB?

A: Mechanical compatibility depends on PCB footprint design. The 929705-01-03-EU provides the closest dimensional match to the original. The 5-146276-3 requires layout verification due to its reduced insulation height and extended post length.
