Key Parameters

Substitute Part Grouping Explanation

Substitution for the Molex 0359780410 is based on the following critical parameters that must remain constant:

• Connector type: Header
• Contact type: Male Pin
• Pitch - mating: 0.156" (3.96mm)
• Number of positions: 4
• Number of rows: 1
• Mounting type: Through Hole
• Termination: Solder
• Shrouding: Shrouded - 1 Wall
• Contact material: Brass
• Contact finish: Tin
• Insulation material: Polyamide (PA66), Nylon 6/6
• Flammability rating: UL94 V-0

The two substitute parts identified—TE Connectivity 1744057-4 and JST B4P-VH-B—meet all critical substitution criteria. Both are active products with equivalent mechanical and electrical interfaces, making them suitable replacements for the obsolete Molex part in applications requiring 4-position, 3.96mm pitch through-hole header connectors.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are active products with current manufacturing support, addressing the obsolescence of the Molex 0359780410. Selection between TE Connectivity 1744057-4 and JST B4P-VH-B should be based on the following factors:

TE Connectivity 1744057-4 is RoHS Compliant and carries a current rating of 7.5A at 250VAC with an operating temperature range of -25°C to 105°C. This part includes board guide features and employs a locking ramp fastening mechanism.

JST B4P-VH-B is ROHS3 Compliant with a current rating of 10A at 250V and an operating temperature range of -25°C to 85°C. The insulation material is polybutylene terephthalate (PBT) glass-filled, and fastening is accomplished via locking ramp.

Both parts meet UL94 V-0 flammability requirements and maintain compatibility with the original Molex connector interface specifications. The choice between these substitutes depends on application-specific requirements for current capacity, temperature range, and insulation material properties.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity 1744057-4 and JST B4P-VH-B be used interchangeably with the Molex 0359780410?

A: Yes. Both substitute parts maintain identical pitch (0.156" / 3.96mm), position count (4), contact type (male pin), mounting method (through-hole), and termination (solder). All three connectors feature shrouded 1-wall design with tin-plated brass contacts and UL94 V-0 flammability rating.

Q: What are the differences in insulation material between the substitutes?

A: The Molex 0359780410 and TE Connectivity 1744057-4 use polyamide (PA66) nylon 6/6 insulation. The JST B4P-VH-B uses polybutylene terephthalate (PBT) glass-filled insulation, which offers different mechanical and thermal properties.

Q: Are there differences in operating temperature ranges?

A: Yes. The TE Connectivity 1744057-4 operates from -25°C to 105°C, while the JST B4P-VH-B operates from -25°C to 85°C. The original Molex part does not specify an operating temperature range.

Q: What is the difference in current rating between the substitutes?

A: The TE Connectivity 1744057-4 is rated for 7.5A at 250VAC. The JST B4P-VH-B is rated for 10A at 250V. The original Molex part does not specify a current rating.

Q: Do the substitute parts have different fastening mechanisms?

A: The Molex 0359780410 uses friction lock fastening. Both substitute parts employ locking ramp fastening. The TE Connectivity 1744057-4 includes board guide features.

Q: Are both substitutes RoHS compliant?

A: The TE Connectivity 1744057-4 is RoHS Compliant. The JST B4P-VH-B is ROHS3 Compliant. Both meet regulatory requirements for lead-free manufacturing.
