Engineering Selection Recommendations

Primary Substitute Recommendation: L717HDA26PD1CH3R

The L717HDA26PD1CH3R from Amphenol ICC (Commercial Products) is the preferred substitute for the obsolete 749769-2. This connector maintains identical form, fit, and function while providing enhanced electrical specifications and full RoHS compliance. The L717HDA26PD1CH3R features:

Active product status with continuous manufacturing support
RoHS Compliant certification
Increased current rating (3A vs. 2A)
Increased voltage rating (250V vs. 125V)
Identical operating temperature range (-55°C ~ 105°C)
Through-hole, right-angle mounting configuration
Board-side flange feature with M3 mounting
Tin-plated steel shell with gold-plated brass contacts
UL94 V-0 flammability rating

Secondary Substitute Options:

10090926-P266VLF (Amphenol ICC FCI) provides an alternative with mating-side female screwlock flange feature and board-edge mounting capability. This variant offers RoHS compliance and enhanced current rating (2.5A per contact) with increased voltage rating (250V).

L717HDA26PD1CH3F (Amphenol ICC Commercial Products) offers mating-side female screwlock configuration as an alternative to board-side mounting, maintaining all other electrical and mechanical specifications of the L717HDA26PD1CH3R.

633-026-263-032 (Mercury United Electronics) provides an alternative source with 3A per contact current rating and shielded features. Operating temperature range is limited to -55°C ~ 85°C, which is acceptable for applications not requiring the full 105°C upper limit.

All recommended substitutes maintain the critical 26-position, 3-row, high-density D-Sub configuration with 0.350" backset spacing and solder termination. All substitutes are active products with established supply chains and manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can the L717HDA26PD1CH3R directly replace the 749769-2 in existing designs?

A: Yes. The L717HDA26PD1CH3R maintains identical form, fit, and function with the 749769-2. Both connectors feature 26-position, 3-row high-density D-Sub configuration, 0.350" backset spacing, through-hole right-angle solder termination, and UL94 V-0 flammability rating. The L717HDA26PD1CH3R provides enhanced electrical performance with higher current and voltage ratings.

Q: What is the difference between the L717HDA26PD1CH3R and L717HDA26PD1CH3F?

A: Both connectors are electrically and mechanically identical. The primary difference is the flange feature configuration. The L717HDA26PD1CH3R features board-side mounting (M3), while the L717HDA26PD1CH3F features mating-side female screwlock (M3). Selection depends on the specific board layout and mating connector configuration.

Q: Are the Amphenol ICC (FCI) variants 10090926-P266VLF and 10090926-P266XLF interchangeable?

A: Both variants maintain identical electrical specifications and 26-position high-density D-Sub configuration. The primary difference is the flange feature: 10090926-P266VLF features mating-side female screwlock (4-40), while 10090926-P266XLF features board-side mounting (4-40). Both support board-edge and through-hole mounting. Selection depends on flange mounting requirements.

Q: Does the 633-026-263-032 from Mercury United Electronics meet the full operating temperature range of the original 749769-2?

A: The 633-026-263-032 operates across -55°C ~ 85°C, which does not include the full 105°C upper limit of the 749769-2. This connector is suitable for applications with maximum operating temperatures at or below 85°C. For applications requiring operation to 105°C, select L717HDA26PD1CH3R, L717HDA26PD1CH3F, 10090926-P266VLF, or 10090926-P266XLF.

Q: What is the significance of RoHS compliance for substitute selection?

A: All recommended substitute parts are RoHS Compliant or ROHS3 Compliant, while the original 749769-2 is RoHS Non-Compliant. RoHS compliance is required for new designs and procurement in many markets and applications. Substitute parts meet current environmental and regulatory requirements.

Q: Can I use the 10090926-P266VLF in applications requiring the original 125V rating?

A: Yes. The 10090926-P266VLF is rated for 250V operation, which exceeds the 125V requirement of the 749769-2. Higher voltage ratings provide additional safety margin and are fully compatible with 125V applications.

Q: What packaging options are available for these substitute connectors?

A: The L717HDA26PD1CH3R, L717HDA26PD1CH3F, 10090926-P266VLF, and 10090926-P266XLF are supplied in Tray packaging. The 633-026-263-032, 633-026-263-043, and 633-026-663-032 variants have packaging specifications not fully detailed in available data. Confirm packaging requirements with supplier documentation for procurement planning.

Q: Are there current inventory considerations for substitute selection?

A: Current inventory levels vary by substitute part. L717HDA26PD1CH3R maintains 1,155 pieces in stock, L717HDA26PD1CH3FC309 maintains 1,095 pieces, 633-026-263-032 maintains 1,156 pieces, and 10090926-P266VLF maintains 1,104 pieces. All recommended substitutes have substantial inventory availability for immediate procurement.
