• Pitch: 0.012" (0.30mm)
• Mounting Type: Surface Mount, Right Angle
• Connector/Contact Type: Contacts, Bottom
• Termination: Solder
• Voltage Rating: 50V
• Current Rating: 0.2A
• Locking Feature: Flip Lock
• Contact Finish: Gold
• Housing Material: Liquid Crystal Polymer (LCP), Glass Filled
• RoHS Status: ROHS3 Compliant

The substitute part 5035665102 belongs to the Easy-On 503566 series and maintains full electrical and mechanical compatibility with the original part while offering active product status and extended operational temperature range.

Engineering Selection Recommendations

The substitute part 5035665102 is suitable for applications currently using the obsolete 5016285191. Selection should be based on the following engineering considerations:

Product Status: The substitute part maintains active product status, ensuring long-term availability and continued manufacturing support from Molex. The original part's obsolete classification necessitates transition to an equivalent alternative.

Compliance & Certifications: Both parts maintain ROHS3 compliance and EAR99 export classification. The substitute part carries additional UL94 HB flammability rating alongside the UL94 V-0 rating, providing expanded material certification coverage.

Operational Envelope: The substitute part extends the operating temperature range from -25°C ~ 85°C to -40°C ~ 105°C, offering enhanced thermal performance for applications requiring broader temperature operation.

Mechanical Compatibility: Height above board increases from 0.035" (0.88mm) to 0.037" (0.95mm). This 0.002" (0.07mm) difference must be evaluated against PCB layout constraints and clearance requirements in the target application.

Contact Material Variation: The substitute part uses Phosphor Bronze contacts instead of Copper Alloy. Both materials maintain gold finish and are suitable for the specified 0.2A current rating and 50V voltage rating.

Packaging: The substitute part is supplied in Tape & Reel (TR) format, which may differ from the original packaging configuration. Verify packaging compatibility with assembly and procurement workflows.

Frequently Asked Questions (FAQ)

Q: Can the 5035665102 be used as a direct replacement for the 5016285191 in existing designs?

A: Yes, the 5035665102 qualifies as a direct electrical and mechanical substitute. Both parts share identical position count (51), pitch (0.3mm), mounting configuration (surface mount, right angle), voltage rating (50V), and current rating (0.2A). The 0.002" height difference must be verified against PCB clearance specifications.

Q: What is the significance of the contact material difference between Copper Alloy and Phosphor Bronze?

A: Both contact materials are suitable for the specified electrical parameters (0.2A, 50V). Phosphor Bronze in the substitute part provides enhanced spring characteristics and wear resistance. This material change does not affect electrical compatibility or performance within the rated specifications.

Q: Does the extended operating temperature range of the substitute part affect compatibility?

A: The substitute part's extended range (-40°C ~ 105°C versus -25°C ~ 85°C) provides additional thermal capability. Applications operating within the original temperature range remain fully compatible. Applications requiring the extended range benefit from the substitute part's enhanced thermal performance.

Q: Are there any PCB layout considerations when transitioning from the original to the substitute part?

A: The height above board increases from 0.035" (0.88mm) to 0.037" (0.95mm). Verify that PCB layout, component placement, and clearance specifications accommodate this 0.002" (0.07mm) increase. All other mechanical dimensions and mounting configurations remain identical.

Q: What packaging format is the substitute part supplied in?

A: The substitute part 5035665102 is supplied in Tape & Reel (TR) format. Confirm compatibility with existing assembly equipment and procurement processes. The original part packaging format should be verified separately if different packaging is required.

Q: Are both parts RoHS compliant?

A: Yes, both the original part 5016285191 and substitute part 5035665102 are ROHS3 compliant. Both parts also maintain identical ECCN (EAR99) and HTSUS (8536.69.4051) classifications for export and tariff purposes.

Q: What is the difference in flammability ratings between the two parts?

A: The original part carries UL94 V-0 rating. The substitute part carries both UL94 V-0 and UL94 HB ratings, providing expanded material certification coverage. Both ratings meet or exceed the original specification.
