Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0520891719 is determined by the following critical parameters:

• Position Count: Must be 17 positions
• Pitch: Must be 0.039" (1.00mm)
• Mounting Configuration: Must be through-hole, right-angle orientation
• Contact Orientation: Must be top-mounted contacts
• Flat Flex Type: Must support FPC or FFC/FPC compatibility
• Termination Style: Must use kinked pin termination
• Electrical Ratings: Substitute must meet or exceed 50V voltage and 0.5A current requirements
• Environmental Compliance: Must maintain RoHS compliance and UL94 V-0 flammability rating

The Amphenol ICC (FCI) part HLW17R-2C7LF meets all critical substitution criteria. This part is active in production, ensuring long-term availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol ICC HLW17R-2C7LF is the qualified substitute for the obsolete Molex 0520891719 based on the following engineering criteria:

Functional Equivalence: Both connectors share identical position count (17), pitch (1.00mm), mounting configuration (through-hole right-angle), and contact orientation (top-mounted). Both use kinked pin termination and phosphor bronze contacts, ensuring mechanical and electrical compatibility at the interface level.

Electrical Performance: The HLW17R-2C7LF exceeds the original part's electrical specifications with 100V voltage rating versus 50V, and 1A current capacity versus 0.5A. This provides additional design margin for applications operating within the original specifications.

Environmental Compliance: Both parts maintain UL94 V-0 flammability certification and RoHS compliance. The substitute extends the operating temperature range to -55°C to 85°C, providing broader environmental coverage.

Reliability Enhancement: The substitute offers 30 mating cycles compared to 20 for the original part, and transitions from obsolete to active production status, ensuring long-term supply availability and manufacturing consistency.

Physical Consideration: The HLW17R-2C7LF has a height above board of 0.154" (3.90mm) versus 0.118" (3.00mm) for the original. PCB layout verification is required to confirm clearance compatibility in space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC HLW17R-2C7LF directly replace the Molex 0520891719 in existing designs?

A: Yes, for applications where the increased height above board (3.90mm versus 3.00mm) does not create mechanical interference. The connector maintains identical electrical interface, position count, pitch, and mounting orientation. PCB layout review is necessary to confirm clearance.

Q: What is the primary reason for substitution?

A: The Molex 0520891719 is classified as obsolete. The Amphenol ICC HLW17R-2C7LF is an active production part, ensuring continued availability and supply chain reliability.

Q: Are there differences in housing material between these connectors?

A: Yes. The original uses Polyamide (PA66) Nylon 6/6, while the substitute uses Polybutylene Terephthalate (PBT) with glass filling. Both materials maintain UL94 V-0 flammability rating. PBT offers improved dimensional stability and chemical resistance.

Q: Does the substitute support both FFC and FPC cable types?

A: The HLW17R-2C7LF is specified for FFC and FPC compatibility with thickness ratings of 0.30mm and 0.33mm. The original Molex part is specified for FPC only at 0.30mm. Verify cable specifications match the substitute's supported thickness range.

Q: What are the electrical rating differences?

A: The substitute provides higher electrical margins: 100V versus 50V for voltage rating, and 1A versus 0.5A for current rating. Applications designed for the original specifications operate safely within the substitute's ratings.

Q: Is mating cycle life a consideration for this substitution?

A: The substitute offers 30 mating cycles versus 20 for the original. For applications requiring frequent connector mating, the substitute provides extended service life.

Q: Are both parts RoHS compliant?

A: Yes. The original is RoHS3 compliant, and the substitute is RoHS compliant. Both meet regulatory requirements for restricted substance elimination.
