Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for FFC connectors is determined by strict alignment of electrical and mechanical parameters. The following criteria establish compatibility:

Critical Parameters for Substitution:

• Number of positions: 50
• Pitch: 0.020" (0.50mm)
• Mounting type: Surface Mount
• Connector/contact type: Contacts, Vertical - 1 Sided
• Voltage rating: 50V
• Current rating: 0.4A
• Operating temperature range: -25°C ~ 85°C
• Locking feature: Flip Lock
• Height above board: 0.159" (4.04mm)
• FFC, FCB thickness: 0.30mm
• Material flammability rating: UL94 V-0
• Termination: Solder

The substitute part Molex 5019515000 meets all critical electrical and mechanical parameters. Variations in actuator material composition and product status (active vs. obsolete) do not affect functional compatibility when all specified parameters align.

Parameter Comparison

Engineering Selection Recommendations

The Molex 5019515000 is the designated manufacturer substitute for the obsolete 0513745073. Both parts maintain identical electrical specifications (50V, 0.4A), mechanical dimensions (50 positions, 0.50mm pitch, 4.04mm height), and compliance certifications (ROHS3, UL94 V-0, REACH Unaffected). The substitute part carries active product status, ensuring continued availability and manufacturing support. Selection of the 5019515000 is appropriate for new designs and production continuity where the original part is no longer available.

Frequently Asked Questions (FAQ)

Q: Can the Molex 5019515000 be used as a direct replacement for the 0513745073?

A: Yes. Both parts share identical electrical ratings (50V, 0.4A), mechanical specifications (50 positions, 0.50mm pitch, vertical single-sided contacts), mounting type (surface mount), and compliance certifications. The substitute part is the active equivalent.

Q: What is the difference between the two parts?

A: The primary difference is product status: the 0513745073 is obsolete, while the 5019515000 is active. The actuator material differs (PPS glass-filled vs. PA9T nylon 9T glass-filled), but this does not affect functional compatibility when all specified parameters align.

Q: Are there packaging differences between these parts?

A: The 0513745073 packaging is not specified in the data. The 5019515000 is supplied in Tape & Reel (TR) packaging, which is standard for surface mount production.

Q: Do these connectors support the same mating cycles?

A: The 0513745073 specifies 20 mating cycles. The 5019515000 does not specify mating cycles in the provided data. Both parts feature identical flip lock mechanisms and zero insertion force (ZIF) operation.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the 0513745073 and 5019515000 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
