Substitute Part Grouping Explanation

Substitution eligibility for the 51936-002 is determined by strict equivalence across the following critical parameters:

  • Connector type: Receptacle with female sockets and blade sockets
  • Position count: 41 positions with 25 positions loaded
  • Pitch: 0.100" (2.54mm)
  • Row configuration: 4 rows
  • Mounting method: Through hole
  • Termination method: Press-fit
  • Contact layout: 32 signal, 9 power
  • Contact finish specification: Gold or Gold, GXT™
  • Contact finish thickness: 30.0µin (0.76µm)
  • Color: Black
  • Flammability rating: UL94 V-0
  • Operating temperature range: -20°C ~ 105°C
  • Guide pin presence: Required

The substitute part 51936-002LF meets all these criteria and is therefore electrically and mechanically equivalent to the main part number.

Engineering Selection Recommendations

The 51936-002LF is the direct equivalent substitute for the obsolete 51936-002. Both parts are manufactured by Amphenol ICC and share identical electrical and mechanical specifications across all critical parameters.

The primary distinction between these parts is product status and compliance posture. The 51936-002LF is an active product with RoHS compliance and REACH applicability, whereas the 51936-002 is obsolete and RoHS non-compliant. For new designs or ongoing production requiring compliance with current environmental regulations, the 51936-002LF is the appropriate selection.

The packaging difference (bulk versus tray) reflects standard industry practice for active versus obsolete product lines and does not affect connector performance or compatibility.

Frequently Asked Questions (FAQ)

Q: Are the 51936-002 and 51936-002LF electrically interchangeable?

A: Yes. Both connectors share identical electrical specifications including connector type, position count, pitch, contact layout (32 signal, 9 power), contact finish, and operating temperature range. They are electrically equivalent.

Q: Are the 51936-002 and 51936-002LF mechanically interchangeable?

A: Yes. Both connectors have identical mechanical specifications including 41 positions with 25 loaded, 0.100" (2.54mm) pitch, 4-row configuration, through-hole mounting, press-fit termination, guide pin features, and black color. They are mechanically equivalent.

Q: Why is the 51936-002 listed as obsolete?

A: The 51936-002 has been superseded by the 51936-002LF, which offers improved compliance status (RoHS compliant) and active product support. The obsolete designation indicates that the original part number is no longer in active production.

Q: What is the difference between the packaging formats?

A: The 51936-002 is supplied in bulk packaging, while the 51936-002LF is supplied in tray packaging. This difference reflects standard industry practice for obsolete versus active product lines. Tray packaging provides improved handling and organization for production environments.

Q: Can I use the 51936-002LF as a direct replacement in existing designs using the 51936-002?

A: Yes. The 51936-002LF is a direct substitute with identical electrical and mechanical specifications. No design modifications are required for substitution.

Q: What is the significance of the RoHS compliance difference?

A: The 51936-002LF is RoHS compliant, meaning it meets restrictions on hazardous substances in electrical and electronic equipment. The 51936-002 is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements, the 51936-002LF is the appropriate selection.
