Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector headers is determined by strict equivalence across critical mechanical and electrical parameters. The Molex 0444722452 qualifies as a substitute for the TE Connectivity 1-794472-1 based on the following matching parameters:

Matching Parameters:

• Connector type: Header
• Contact type: Male Pin
• Number of positions: 24
• Number of rows: 2
• Pitch - mating: 0.165" (4.20mm)
• Row spacing - mating: 0.165" (4.20mm)
• Shrouding: Shrouded - 4 Wall
• Mounting type: Through Hole
• Termination: Solder
• Fastening type: Locking Ramp
• Contact shape: Square
• Contact material: Copper Alloy
• Contact finish - mating: Tin
• Insulation height: 0.504" (12.80mm)
• Contact length - post: 0.138" (3.50mm)
• Insulation material: Polyamide (PA), Nylon
• Moisture sensitivity level: 1 (Unlimited)
• Product status: Active

These parameters establish functional and mechanical compatibility for direct substitution in applications requiring 24-position rectangular connector headers with 4.20mm pitch and through-hole solder termination.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 1-794472-1 and Molex 0444722452 are active products with RoHS compliance status. The TE Connectivity part carries RoHS Compliant certification, while the Molex substitute carries ROHS3 Compliant certification. Both parts maintain unlimited moisture sensitivity rating and are suitable for through-hole solder applications.

The TE Connectivity 1-794472-1 specifies a UL94 V-0 flammability rating and 600VAC voltage rating. The Molex 0444722452 specifies UL94 V-2 flammability rating with voltage rating not specified in available documentation.

Contact finish thickness differs between the two parts: TE Connectivity specifies 118.1µin (3.00µm) while Molex specifies 100.0µin (2.54µm). Insulation material composition differs slightly: TE Connectivity uses Polyamide (PA) Nylon while Molex uses Polyamide (PA66) Nylon 6/6.

Selection between these parts should be based on specific application requirements regarding flammability rating, voltage rating, and contact finish thickness specifications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0444722452 be used as a direct replacement for the TE Connectivity 1-794472-1?

A: The Molex 0444722452 shares all critical mechanical parameters with the TE Connectivity 1-794472-1, including 24-position configuration, 4.20mm pitch, 2-row layout, shrouded 4-wall design, through-hole mounting, and solder termination. Both parts feature locking ramp fastening and square contact geometry. Substitution is mechanically and functionally compatible based on these matching parameters.

Q: What are the differences in flammability ratings between these parts?

A: The TE Connectivity 1-794472-1 carries a UL94 V-0 flammability rating, while the Molex 0444722452 carries a UL94 V-2 rating. Applications requiring V-0 rated components must use the TE Connectivity part.

Q: How do the contact finish thicknesses compare?

A: The TE Connectivity 1-794472-1 specifies tin contact finish at 118.1µin (3.00µm) thickness. The Molex 0444722452 specifies tin contact finish at 100.0µin (2.54µm) thickness. Both use tin as the contact finish material.
