Amphenol ICC 95242-409 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 95242-409 is an 18-position receptacle connector with 0.100" (2.54mm) pitch, designed for board-to-board applications in surface mount configurations. This component features a push-pull fastening mechanism, tin-lead contact finish, and thermoplastic glass-filled insulation rated UL94 V-0. The part is currently obsolete, which necessitates identification of functionally equivalent alternatives for ongoing system support and new designs.

Key Parameters

Substitute Part Grouping Explanation

The 95242-409LF qualifies as a direct substitute based on the following critical parameters that determine functional equivalence:

• Identical connector type (Receptacle, Bottom or Top Entry)
• Identical number of positions (18)
• Identical mating pitch (0.100" / 2.54mm)
• Identical row configuration (2 rows at 0.100" spacing)
• Identical mounting type (Surface Mount)
• Identical fastening mechanism (Push-Pull)
• Identical contact type (Female Socket)
• Identical insulation material and flammability rating (Thermoplastic, Glass Filled; UL94 V-0)
• Same series designation (Dubox™)

The primary difference is the contact finish specification: the substitute uses tin finish (78.7µin / 2.00µm) versus the original tin-lead finish (196.9µin / 5.00µm). Both finishes are applied to mating and post contacts consistently within each part variant.

Parameter Comparison

Engineering Selection Recommendations

The 95242-409LF is the active production equivalent of the obsolete 95242-409. Selection between these parts should be based on the following criteria:

For new designs and ongoing production: The 95242-409LF is the appropriate choice. This part maintains full mechanical and electrical compatibility while offering RoHS compliance, which the original part does not provide. Both parts share identical connector geometry, pitch, row configuration, and fastening characteristics, ensuring direct interchangeability at the board level.

Contact finish consideration: The substitute uses a thinner tin finish (78.7µin / 2.00µm) compared to the original tin-lead finish (196.9µin / 5.00µm). Both finishes are applied consistently to mating and post contacts. The thinner tin finish in the 95242-409LF reflects current industry standards and RoHS compliance requirements.

Compliance status: The 95242-409LF achieves RoHS compliance, whereas the original 95242-409 does not. This distinction is significant for applications subject to RoHS regulations or customer requirements mandating compliant components.

Frequently Asked Questions (FAQ)

Q: Are the 95242-409 and 95242-409LF mechanically interchangeable?

A: Yes. Both parts are identical in connector type, position count, mating pitch (0.100" / 2.54mm), row spacing, mounting type (surface mount), and fastening mechanism (push-pull). They occupy the same footprint and mate with identical plug connectors.

Q: What is the difference between the contact finishes?

A: The original 95242-409 uses tin-lead finish at 196.9µin (5.00µm) thickness on both mating and post contacts. The 95242-409LF uses tin finish at 78.7µin (2.00µm) thickness on both mating and post contacts. Both finishes provide equivalent electrical performance and solderability for surface mount applications.

Q: Why is the 95242-409 listed as obsolete?

A: The 95242-409 is obsolete due to the transition to RoHS-compliant alternatives. The 95242-409LF represents the current production equivalent and is actively manufactured.

Q: Does the packaging difference affect compatibility?

A: No. The original 95242-409 packaging is not specified in the available data. The 95242-409LF is supplied in tube packaging. Packaging affects handling and storage logistics but does not impact electrical or mechanical compatibility.

Q: Can I use the 95242-409LF as a direct replacement in existing assemblies designed for the 95242-409?

A: Yes. The 95242-409LF is a direct substitute. The identical mechanical dimensions, pitch, row configuration, and fastening type ensure compatibility with existing mating connectors and PCB layouts.

Q: Are there any compliance differences between these parts?

A: The 95242-409LF is RoHS compliant, while the 95242-409 is not. Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications. Both have MSL rating of 1 (Unlimited) and UL94 V-0 flammability rating.
