Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0026624140 and TE Connectivity 4-644615-4 are active products with identical regulatory compliance profiles. Both parts maintain ROHS3 compliance, REACH unaffected status, and UL94 V-0 flammability ratings. The substitute part carries additional operational specifications including operating temperature range (-55°C ~ 105°C) and voltage rating (600VAC), which provide defined performance boundaries for applications requiring these parameters.

Selection between these parts should be based on supply availability, lead time requirements, and existing design validation history with either manufacturer's connector series. Both parts satisfy the core mechanical and electrical requirements for 14-position, 0.156" pitch rectangular connector applications in automotive, industrial, medical, and telecommunications environments.

Frequently Asked Questions (FAQ)

Q: What makes the TE Connectivity 4-644615-4 a valid substitute for the Molex 0026624140?

A: Both connectors share identical core specifications: 14-position, single-row header configuration with 0.156" (3.96mm) pitch, through-hole mounting, shrouded design with friction lock fastening, and solder termination. Both maintain UL94 V-0 flammability rating and ROHS3 compliance, meeting the critical parameters that determine mechanical and electrical compatibility in rectangular connector applications.

Q: Are there differences in contact finish thickness between these parts?

A: Yes. The Molex 0026624140 specifies 60.0µin (1.52µm) contact finish thickness on both mating and post surfaces. The TE Connectivity 4-644615-4 specifies 150.0µin (3.81µm) on both surfaces. This difference does not affect substitution compatibility but may influence contact resistance characteristics in high-cycle mating applications.

Q: What is the difference in insulation material between these connectors?

A: The Molex part uses polyester glass-filled insulation, while the TE Connectivity part uses thermoplastic glass-filled insulation. Both materials achieve UL94 V-0 flammability rating and support identical operating environments. The material difference reflects manufacturer design choices and does not impact mechanical or electrical compatibility.

Q: Do both parts support the same number of loaded positions?

A: The Molex 0026624140 specifies 13 positions loaded, while the TE Connectivity 4-644615-4 specifies all positions loaded. This indicates the TE part is supplied with all 14 contact positions populated, whereas the Molex part may be supplied with one position vacant. Verify actual loaded position requirements for your application.

Q: Are there differences in contact length specifications?

A: Yes. The Molex 0026624140 specifies 0.450" (11.43mm) mating contact length and 0.140" (4.66mm) post length, with 0.720" (18.29mm) overall contact length. The TE Connectivity 4-644615-4 specifies 0.450" (11.43mm) mating contact length and 0.125" (3.18mm) post length, with 0.700" (17.78mm) overall contact length. These minor dimensional variations reflect series design differences and do not affect standard board-to-cable connection applications.

Q: What is the difference in insulation height between these parts?

A: The Molex 0026624140 specifies 0.446" (11.33mm) insulation height, while the TE Connectivity 4-644615-4 specifies 0.545" (13.84mm). This dimensional difference should be verified against PCB layout and mating connector specifications to ensure proper mechanical fit in constrained mounting environments.

Q: Do both parts carry the same regulatory certifications?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification with identical HTSUS code 8536.69.4040. Both maintain moisture sensitivity level 1 (unlimited) and UL94 V-0 flammability rating, ensuring equivalent regulatory status for industrial and commercial applications.
