Parameter Comparison

Engineering Selection Recommendations

Part 147278-8 (Surface Mount Configuration): Select this part for applications requiring surface mount assembly on printed circuit boards. This configuration is suitable for high-density PCB layouts where through-hole mounting is not feasible. The gold-plated mating contacts provide enhanced corrosion resistance. The RoHS non-compliant status indicates this part contains lead-based solder finish and is suitable for applications without RoHS restrictions.

Part 5-103634-8 (Through Hole Configuration): Select this part for applications requiring through-hole mounting on printed circuit boards. This configuration provides mechanical stability through post insertion into PCB vias. The RoHS Compliant status indicates lead-free composition, making this part suitable for applications subject to RoHS regulations. The tin-plated mating contacts meet standard through-hole connector specifications.

Compliance Considerations: The choice between these parts depends on regulatory requirements and assembly methodology. Applications requiring RoHS compliance must use part 5-103634-8. Applications with lead-based solder restrictions or environmental regulations must also use the RoHS-compliant substitute. Both parts maintain identical electrical performance, current rating, temperature range, and flammability certification.

Frequently Asked Questions (FAQ)

Q: Can part 5-103634-8 be used as a direct replacement for 147278-8 in surface mount applications?

A: No. Part 5-103634-8 is configured for through-hole mounting, while 147278-8 is designed for surface mount assembly. The mounting type difference requires different PCB design and assembly processes. Substitution is only valid when the application can accommodate through-hole mounting.

Q: What is the primary difference between these two connector parts?

A: The primary difference is the mounting type. Part 147278-8 uses surface mount technology with solder pads on the PCB surface. Part 5-103634-8 uses through-hole technology with leads inserted through PCB vias. Both parts share identical electrical specifications, pitch, position count, and shrouding design.

Q: Are the contact finishes interchangeable between these parts?

A: The contact finishes differ between the parts. Part 147278-8 features gold-plated mating contacts with tin-lead post finish. Part 5-103634-8 features tin-plated mating contacts with tin post finish. Both finishes are suitable for their respective mounting types and provide adequate electrical performance for the 3A current rating.

Q: Which part should be selected for RoHS-compliant applications?

A: Part 5-103634-8 is RoHS Compliant and must be used for applications subject to RoHS regulations. Part 147278-8 is RoHS non-compliant due to lead-based solder finish and is not suitable for RoHS-restricted applications.

Q: Do both parts operate within the same temperature range?

A: Yes. Both parts operate within the identical temperature range of -65°C to 105°C and maintain the same UL94 V-0 flammability rating, ensuring equivalent thermal performance across both mounting configurations.

Q: What is the packaging difference between these parts?

A: Part 147278-8 packaging is not specified in the provided data. Part 5-103634-8 is supplied in Tube packaging. Packaging differences do not affect electrical or mechanical compatibility; they relate only to order quantity and storage considerations.

Q: Can these parts be used interchangeably in medical applications?

A: Both parts are rated for medical applications. However, substitution depends on the specific PCB design and assembly method. Surface mount applications require part 147278-8, while through-hole applications require part 5-103634-8. The application's mounting methodology determines which part is appropriate.

Q: Are the mechanical dimensions identical between these parts?

A: The mating contact length (0.230" / 5.84mm) and insulation height (0.200" / 5.08mm) are identical. Part 5-103634-8 specifies a contact post length of 0.130" (3.30mm), which is not specified for part 147278-8. The mechanical compatibility depends on the specific PCB design and mounting requirements.
