Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0541323633 is determined by the following critical parameters:

• Number of Positions: Must be 36
• Pitch: Must be 0.020" (0.50mm)
• Mounting Type: Must be Surface Mount, Right Angle
• Voltage Rating: Must be 50V
• Current Rating: Must be 0.5A
• Locking Feature: Must be Slide Lock
• Termination: Must be Solder

The substitute parts listed meet these core electrical and mechanical requirements. However, variations exist in contact orientation (bottom vs. top), contact finish material, housing composition, and product status. These variations are documented in the parameter comparison table below.

Engineering Selection Recommendations

Molex 0541323697 is the primary equivalent substitute. This part maintains identical electrical specifications, mechanical dimensions, and contact configuration (bottom-mounted) as the original 0541323633. The key difference is active product status, ensuring long-term availability and supply chain continuity. Operating temperature range is narrower (-20°C ~ 85°C vs. -40°C ~ 85°C), which must be evaluated against application requirements. Packaging is supplied as Tape & Reel (TR) rather than Cut Tape (CT).

Amphenol ICC 62684-362100ALF and 62684-36210E9ALF are cross-manufacturer alternatives with identical electrical ratings and pitch specifications. Both parts feature top-mounted contacts rather than bottom-mounted, requiring PCB layout modification. Contact finish is gold instead of tin bismuth, providing enhanced corrosion resistance. Operating temperature range extends to -55°C, offering broader environmental capability. The 62684-362100ALF maintains active product status, while 62684-36210E9ALF is obsolete.

Selection between these substitutes depends on PCB design constraints (contact orientation), environmental operating range requirements, and supply availability. All listed parts comply with RoHS and REACH regulations as specified.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0541323697 be used as a direct replacement for the 0541323633?

A: Yes, the 0541323697 is a direct functional equivalent. Both parts share identical pitch (0.5mm), position count (36), mounting configuration (surface mount, right angle), and contact orientation (bottom). The primary difference is product status (active vs. obsolete) and packaging format (Tape & Reel vs. Cut Tape). Operating temperature range differs by 20°C at the lower limit; verify application requirements before selection.

Q: What is the key difference between Molex and Amphenol ICC substitutes?

A: The Amphenol ICC parts (62684-362100ALF and 62684-36210E9ALF) feature top-mounted contacts, whereas the Molex parts feature bottom-mounted contacts. This orientation difference requires PCB redesign and cannot be accommodated through simple component swapping. Contact finish also differs: Amphenol uses gold plating versus Molex tin bismuth finish.

Q: Are the Amphenol ICC parts compatible with existing PCB designs?

A: Amphenol ICC parts are electrically and mechanically compatible in terms of pitch, position count, and voltage/current ratings. However, the top-mounted contact orientation requires PCB layout modification. These parts are suitable only for new designs or redesigned assemblies that accommodate top-mounted contact configuration.

Q: What packaging options are available?

A: The Molex 0541323633 is supplied in Cut Tape (CT) packaging. The Molex 0541323697 substitute is supplied in Tape & Reel (TR) format. Amphenol ICC 62684-362100ALF is available in Cut Tape (CT), while 62684-36210E9ALF is supplied in Tape & Reel (TR). Packaging selection affects handling, storage, and automated assembly compatibility.

Q: Do all substitute parts meet RoHS compliance?

A: Yes, all listed parts comply with RoHS regulations. The Molex parts are ROHS3 compliant. The Amphenol ICC parts are RoHS compliant. All parts are suitable for applications requiring RoHS-compliant component sourcing.

Q: What is the operating temperature range difference, and does it matter?

A: The original Molex 0541323633 operates from -40°C to 85°C. The Molex 0541323697 substitute operates from -20°C to 85°C, a 20°C reduction at the lower limit. The Amphenol ICC parts operate from -55°C to 85°C, providing extended low-temperature capability. Application environment determines whether this difference is critical.
