Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 86381-424 are identified based on strict electrical and mechanical compatibility criteria. The primary substitution logic is based on the following key parameters:

• Connector pitch of 0.100" (2.54mm)
• 24-position, 2-row configuration
• Male pin contact type
• Through-hole, right-angle mounting
• Board-to-board application style
• Push-pull fastening mechanism
• UL94 V-0 flammability rating

The substitute part TE Connectivity AMP Connectors 1-826634-2 meets these core requirements while offering variations in contact material, finish specifications, and operating temperature range. Both parts are classified as active products with current manufacturing status.

Parameter Comparison

Engineering Selection Recommendations

Both the 86381-424 and 1-826634-2 are active production parts suitable for 24-position, 2.54mm pitch board-to-board connector applications. Selection between these parts should be based on the following criteria:

The 1-826634-2 (TE Connectivity) offers ROHS3 compliance, making it the preferred choice for applications subject to RoHS regulations. The 86381-424 (Amphenol ICC) is RoHS non-compliant and should be selected only when legacy or non-regulated applications explicitly require this part.

The 1-826634-2 provides a specified operating temperature range of -65°C to 105°C and a current rating of 5A, offering defined performance parameters for thermal and electrical design calculations. The 86381-424 does not specify these parameters.

Contact finish differences exist: the 86381-424 uses tin plating on mating contacts, while the 1-826634-2 uses gold plating. Gold-plated contacts provide superior corrosion resistance and lower contact resistance, particularly beneficial in high-reliability or harsh environment applications.

Both parts share identical core mechanical specifications: 24 positions, 2 rows, 2.54mm pitch, through-hole right-angle mounting, and UL94 V-0 flammability rating. Minor dimensional variations in contact length and insulation height are within typical manufacturing tolerances for this connector class.

Frequently Asked Questions (FAQ)

Q: Can the 1-826634-2 directly replace the 86381-424 in existing designs?

A: Yes, the 1-826634-2 is mechanically and electrically compatible as a direct substitute. Both connectors share identical pitch (2.54mm), position count (24), row configuration (2), and mounting style (through-hole right-angle). Minor dimensional differences in contact length (0.264" vs. 0.250") and insulation height (0.219" vs. 0.190") are within acceptable tolerances for board-to-board mating applications.

Q: What are the key differences between these two parts?

A: Primary differences include: (1) RoHS compliance status—1-826634-2 is ROHS3 compliant while 86381-424 is non-compliant; (2) contact finish—1-826634-2 uses gold plating versus tin on the 86381-424; (3) contact material—1-826634-2 uses brass versus phosphor bronze on the 86381-424; (4) specified operating temperature and current rating available only for the 1-826634-2; (5) insulation color differs (green vs. black).

Q: Which part should be selected for new designs?

A: The 1-826634-2 is recommended for new designs due to ROHS3 compliance, specified operating temperature range (-65°C to 105°C), defined current rating (5A), and gold-plated contacts offering superior reliability. The 86381-424 should be reserved for legacy system maintenance or applications with explicit non-RoHS requirements.

Q: Are there any compatibility concerns with PCB footprints?

A: Both connectors use identical 2.54mm pitch and 2-row configuration, ensuring footprint compatibility. Minor variations in overall connector dimensions do not affect PCB land pattern design. Verify mounting hole spacing and through-hole diameter specifications with your PCB design software to confirm fit.

Q: What is the significance of the contact finish difference?

A: Gold plating (1-826634-2) provides superior corrosion resistance, lower contact resistance, and extended mating cycle life compared to tin plating (86381-424). Gold-plated contacts are preferred for applications requiring high reliability, frequent mating cycles, or exposure to corrosive environments.

Q: Do both parts have the same moisture sensitivity level?

A: Yes, both the 86381-424 and 1-826634-2 are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. Standard component storage practices apply.
