Key Parameters

Substitute Part Grouping Explanation

Substitution for the 0781271349 is determined by the following critical parameters that must remain constant:

• Number of Positions: 34
• Pitch: 0.020" (0.50mm)
• Mounting Type: Surface Mount
• Connector Type: Contacts, Vertical - 1 Sided
• Voltage Rating: 50V
• Current Rating: 0.5A
• Operating Temperature Range: -40°C ~ 85°C
• Flammability Rating: UL94 V-0
• Termination: Solder
• FFC/FPC Thickness: 0.30mm
• Height Above Board: 0.161" (4.10mm)
• Cable End Type: Tapered
• Contact Finish: Tin Bismuth
• Contact Finish Thickness: 39.4µin (1.00µm)

The parametric equivalent 0781193410 maintains all critical electrical and mechanical parameters while differing in housing material, contact material, and mating cycle rating. The MFR recommended substitute 0781273410 represents an alternative connector design within the same product family.

Parameter Comparison

Engineering Selection Recommendations

The 0781193410 serves as the parametric equivalent substitute for the obsolete 0781271349. Both parts maintain identical electrical specifications (50V, 0.5A), mechanical configuration (34 positions, 0.5mm pitch, surface mount), and thermal operating range (-40°C to 85°C). The 0781193410 is currently in active production status with RoHS compliance and unlimited moisture sensitivity level rating, making it suitable for direct replacement in new designs and production continuations.

The 0781273410 is identified as the manufacturer-recommended alternative within the Molex product portfolio. Limited parametric data is provided for this part; however, it is classified as active and RoHS compliant.

Both substitute parts carry ECCN EAR99 classification and maintain compliance with applicable regulatory standards. Selection between the parametric equivalent and manufacturer-recommended substitute should be based on specific application requirements, PCB layout constraints, and connector interface specifications not detailed in the provided parameters.

Frequently Asked Questions (FAQ)

Q: Can the 0781193410 be used as a direct replacement for the 0781271349?

A: The 0781193410 maintains all critical electrical and mechanical parameters required for functional equivalence. Both parts feature 34 positions, 0.5mm pitch, 50V voltage rating, 0.5A current rating, and identical operating temperature range. The primary differences are housing material (LCP versus polyamide), contact material (phosphor bronze versus copper alloy), and mating cycle rating (10 versus 20 cycles). These differences do not affect electrical compatibility in applications matching the specified parameters.

Q: What is the difference between the parametric equivalent and the manufacturer-recommended substitute?

A: The 0781193410 is classified as a parametric equivalent because it shares all critical electrical and mechanical specifications with the main part. The 0781273410 is the manufacturer-recommended alternative, though limited technical parameters are provided for this part. The manufacturer recommendation indicates this part represents an approved alternative within the Molex product family.

Q: Are both substitute parts RoHS compliant?

A: Yes. The 0781193410 is RoHS compliant, and the 0781273410 is RoHS compliant. Both parts meet regulatory requirements for lead-free and restricted substance compliance.

Q: What is the packaging format for the 0781193410?

A: The 0781193410 is supplied in Tape & Reel (TR) packaging format, which differs from the main part's packaging specification. Tape & Reel packaging is standard for high-volume surface mount assembly operations.

Q: How do the mating cycle ratings differ between the main part and substitute?

A: The 0781271349 is rated for 20 mating cycles, while the 0781193410 is rated for 10 mating cycles. This difference reflects the mechanical durability of each connector design. Applications requiring frequent connector mating should account for this specification difference.
