Key Parameters

Substitute Part Grouping Explanation

Substitution of the 87402-115 is determined by strict equivalence across the following critical parameters:

• Connector type, contact type, and mating style (Header, Male Pin, Board to Board)
• Position count and row configuration (30 positions, 2 rows)
• Pitch specifications (0.050" mating pitch, 0.050" row spacing)
• Mounting method and termination (Through Hole, Right Angle, Solder)
• Fastening mechanism (Push-Pull)
• Shrouding configuration (Shrouded - 4 Wall)
• Contact geometry and dimensions (Square shape, 0.130" mating length, 0.075" post length, 0.240" insulation height)
• Electrical performance (1A DC current rating)
• Environmental specifications (Operating temperature -55°C ~ 130°C, UL94 V-0 flammability)

The substitute part 87402-115LF maintains full electrical and mechanical compatibility with the original specification while offering active product status and improved compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 87402-115LF is the direct equivalent substitute for the obsolete 87402-115. Both parts share identical electrical and mechanical specifications across all critical parameters including connector geometry, contact configuration, pitch, mounting method, and environmental ratings.

The primary distinction between the two parts is product status and compliance posture. The 87402-115 is classified as obsolete with RoHS non-compliant status, while the 87402-115LF maintains active product status with RoHS compliance. The contact finish on the post differs slightly (Tin-Lead versus Tin), though both maintain equivalent contact finish thickness specifications.

For new designs or ongoing procurement requirements, the 87402-115LF is the appropriate selection due to its active availability and regulatory compliance. For legacy systems currently utilizing the 87402-115, the 87402-115LF provides direct functional and mechanical compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Are the 87402-115 and 87402-115LF mechanically interchangeable?

A: Yes. Both parts maintain identical dimensions, contact geometry, pitch specifications, and mounting configurations. The connectors are mechanically interchangeable in board-to-board applications.

Q: What is the difference between the contact finishes on the post?

A: The 87402-115 uses Tin-Lead finish while the 87402-115LF uses Tin finish on the post contacts. Both maintain 200.0µin (5.08µm) thickness. The mating contact finish remains Gold or Gold, GXT™ on both parts at 30.0µin (0.76µm).

Q: Why is the 87402-115 listed as obsolete?

A: The 87402-115 has been superseded by the 87402-115LF, which offers improved compliance characteristics and active product status. Amphenol ICC continues to support the Rib-Cage™ series through the active 87402-115LF variant.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance status reflects manufacturing process and material composition rather than electrical or mechanical performance. Both parts deliver identical electrical specifications and operating characteristics.

Q: What packaging is available for the substitute part?

A: The 87402-115LF is supplied in Tube packaging. The original 87402-115 packaging specification was not provided in the technical data.

Q: Can the 87402-115LF be used in applications originally designed for the 87402-115?

A: Yes. The 87402-115LF provides full functional and mechanical compatibility. No design modifications are required for direct substitution in existing applications.
