Substitute Part Grouping Explanation

Substitute parts for the Molex 0026489073 are qualified based on the following critical parameters that determine functional interchangeability:

Pitch - Mating: 0.156" (3.96mm) — must match exactly for PCB footprint compatibility
Number of Positions: 7 — electrical interface requirement
Contact Type: Male Pin — mating interface specification
Mounting Type: Through Hole — assembly process compatibility
Termination: Solder — connection method
Shrouding: Shrouded - 1 Wall — mechanical protection and alignment
Material Flammability Rating: UL94 V-0 — safety compliance requirement

The following parts meet these substitution criteria:

TE Connectivity 640445-7 (MTA-156 Series)
TE Connectivity 644752-7 (MTA-156 Series)

Both substitute parts maintain identical pitch, position count, contact type, mounting method, and flammability rating. Variations in contact length and insulation height do not affect functional compatibility in standard applications.

Engineering Selection Recommendations

All three parts—Molex 0026489073, TE Connectivity 640445-7, and TE Connectivity 644752-7—are actively produced and ROHS3 compliant. Selection between these parts should be based on:

Molex 0026489073: Primary choice when specified in original design documentation. Maintains KK396 and 41671 series compatibility. Contact length specifications (0.447" mating, 0.125" post) are optimized for standard through-hole PCB applications.

TE Connectivity 640445-7: Functionally equivalent substitute with MTA-156 series designation. Shorter mating contact length (0.400") and reduced insulation height (0.425") may be suitable for space-constrained layouts. Rated for -55°C to 105°C operating temperature and 600VAC voltage rating.

TE Connectivity 644752-7: Functionally equivalent substitute with MTA-156 series designation. Extended post contact length (0.175") accommodates thicker PCB assemblies or wire gauge applications. Maintains identical mating contact length and insulation height as 640445-7. Rated for -55°C to 105°C operating temperature and 600VAC voltage rating.

All parts carry UL94 V-0 flammability certification and unlimited moisture sensitivity rating, ensuring compliance with automotive, industrial, and medical application standards.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity 640445-7 and 644752-7 be used interchangeably with Molex 0026489073?

A: Yes, both TE Connectivity parts are functionally equivalent substitutes. All three connectors share identical pitch (0.156"), position count (7), contact type (male pin), mounting method (through hole), and flammability rating (UL94 V-0). The primary differences are contact length specifications, which do not affect compatibility in standard applications.

Q: What is the difference between TE Connectivity 640445-7 and 644752-7?

A: Both parts are MTA-156 series headers with identical mating contact length (0.400") and insulation height (0.425"). The key difference is post contact length: 640445-7 features 0.125" post length, while 644752-7 features 0.175" post length. Select 644752-7 for applications requiring extended post engagement or thicker PCB assemblies.
