Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 68423-136H are identified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Compatibility Criteria:

• Pitch - Mating: 0.100" (2.54mm)
• Connector Type: Header with male pins
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Shape: Square
• Contact Finish - Mating: Gold plating
• Contact Finish Thickness - Mating: 30.0µin (0.76µm)
• Material Flammability Rating: UL94 V-0
• Insulation Color: Black
• Current Rating: 3A
• Operating Temperature Range: -65°C ~ 130°C

Secondary Compatibility Considerations:

• Number of Positions: 36 (primary) or 40 (limited compatibility)
• Contact Length - Mating: 0.318" (8.08mm) ± tolerance
• Contact Length - Post: 0.110" ~ 0.120" (2.79mm ~ 3.05mm)
• Insulation Height: 0.095" ~ 0.138" (2.41mm ~ 4.60mm)
• Style: Board to Board or Board to Board/Cable

Substitutes are grouped into two categories: direct replacements (same position count) and functional alternatives (different position count but compatible electrical and mechanical characteristics).

Engineering Selection Recommendations

68458-136HLF (Amphenol ICC - Direct Substitute)

This is the primary recommended substitute for the obsolete 68423-136H. Both connectors are from the same BERGSTIK® II series and share identical electrical and mechanical specifications, including 36 positions, 0.100" pitch, contact dimensions, and operating temperature range. The 68458-136HLF is currently in active production status with 895 units in stock. The primary difference is RoHS compliance: the 68458-136HLF is RoHS Compliant, whereas the original 68423-136H is RoHS non-compliant. This substitution is suitable for new designs and legacy system replacements where RoHS compliance is required or preferred.

0022288365 (Molex KK254 Series - Direct Position Substitute)

The Molex 0022288365 provides a direct 36-position alternative from an established connector manufacturer. It maintains the same 0.100" pitch, through-hole right-angle mounting, solder termination, and push-pull fastening. Contact dimensions are within acceptable tolerance (mating contact length 0.324" vs. 0.318"), and all critical electrical parameters align. The connector is ROHS3 Compliant and currently in active production with 937 units in stock. This option is suitable when multi-source qualification is required or when Molex connector ecosystem integration is preferred.

4-146305-0 (TE Connectivity AMPMODU Mod II - Functional Alternative)

The TE Connectivity 4-146305-0 is a 40-position variant that shares the same 0.100" pitch, through-hole right-angle mounting, and solder termination as the original 68423-136H. This connector is suitable only when the application can accommodate the additional 4 positions or when the connector will be used in a configuration where only 36 of the 40 positions are populated. The operating temperature range is -65°C ~ 105°C, which is 25°C lower than the original specification. This part is RoHS non-compliant and currently in active production with 968 units in stock. Selection of this part requires confirmation that the increased insulation height (0.138" vs. 0.095") and position count do not create mechanical or electrical conflicts in the target application.

Frequently Asked Questions (FAQ)

Q: Can I use the 68458-136HLF as a direct replacement for the 68423-136H?

A: Yes. The 68458-136HLF is a direct substitute from the same BERGSTIK® II series with identical position count (36), pitch (0.100"), contact dimensions, and operating temperature range (-65°C ~ 130°C). Both are unshrouded, through-hole, right-angle headers with male pins and gold-plated contacts. The primary difference is that 68458-136HLF is RoHS Compliant while the original is RoHS non-compliant.

Q: What are the key differences between the Molex 0022288365 and the original 68423-136H?

A: Both connectors have 36 positions at 0.100" pitch and are suitable for board-to-board applications. The Molex part has a slightly longer mating contact (0.324" vs. 0.318") and marginally taller insulation height (0.098" vs. 0.095"). The Molex connector is classified as a Header, Breakaway type, offering modular configuration options. The Molex part is ROHS3 Compliant and currently active in production.

Q: Why is the TE Connectivity 4-146305-0 listed as a substitute if it has 40 positions instead of 36?

A: The 4-146305-0 is a functional alternative when the application design permits use of a 40-position connector or when only 36 of the 40 positions will be utilized. It maintains the same 0.100" pitch, through-hole right-angle mounting, solder termination, and push-pull fastening. However, the increased insulation height (0.138" vs. 0.095") and lower maximum operating temperature (-65°C ~ 105°C vs. -65°C ~ 130°C) must be evaluated against specific application requirements.

Q: Are all substitute parts rated for 3A current?

A: The 68458-136HLF and 4-146305-0 are both rated for 3A current, matching the original 68423-136H. The Molex 0022288365 does not specify a current rating in the provided data; current capacity should be confirmed with the manufacturer or datasheet before selection.

Q: What is the difference between the packaging options for these connectors?

A: The 68423-136H original part does not specify packaging. The 68458-136HLF is supplied in Bulk packaging. The Molex 0022288365 is supplied in Bulk packaging. The TE Connectivity 4-146305-0 is supplied in Tray packaging. Packaging selection may affect handling, storage, and integration into production workflows.

Q: Which substitute part should I select for a new design?

A: For new designs requiring RoHS compliance, the 68458-136HLF (Amphenol ICC) is the primary recommendation due to identical specifications and active production status. For multi-source qualification, the Molex 0022288365 provides an equivalent alternative. The TE Connectivity 4-146305-0 should be selected only when the 40-position configuration and lower operating temperature range are compatible with application requirements.

Q: Are there any compliance or certification differences between these parts?

A: All parts meet UL94 V-0 flammability requirements and have MSL 1 (Unlimited) moisture sensitivity ratings. The 68458-136HLF is RoHS Compliant, the Molex 0022288365 is ROHS3 Compliant, and the TE Connectivity 4-146305-0 is RoHS non-compliant. REACH status varies: 68458-136HLF is REACH Affected, Molex 0022288365 is REACH Unaffected, and TE Connectivity 4-146305-0 is REACH Affected.
