Substitute Part Grouping Explanation

Substitution eligibility for the 68683-413 is determined by the following core parameters:

26-position configuration with 2-row layout
0.100" (2.54mm) mating pitch and row spacing
Board-to-board receptacle connector style
Through-hole solder termination
Push-pull fastening mechanism
Female socket contact type
UL94 V-0 flammability rating

The three identified substitute parts (1-215307-3, 6-534206-3, and 803-43-026-10-001000) satisfy these core requirements. Variations in contact finish material (gold vs. tin), insulation material composition, contact shape, and post contact material represent acceptable engineering substitutions when electrical and mechanical interface requirements are met.

Engineering Selection Recommendations

All three substitute parts maintain active product status and satisfy the core mechanical and electrical interface requirements of the 68683-413. Selection among substitutes should be based on the following considerations:

1-215307-3 (TE Connectivity AMPMODU HV-100): This part offers ROHS3 compliance and gold-plated mating contacts. The kinked pin termination provides enhanced mechanical retention during solder reflow. Insulation height matches the original specification at 0.276" (7.00mm).

6-534206-3 (TE Connectivity AMPMODU Mod II): This part provides ROHS3 compliance with gold-plated mating contacts and a rated current capacity of 2A. The insulation height is 0.320" (8.13mm), which is 0.044" taller than the original part. Operating temperature range matches the original specification (-65°C ~ 125°C).

803-43-026-10-001000 (Mill-Max 803 Series): This part offers ROHS3 compliance and REACH Unaffected status. It features a higher current rating of 4.5A and beryllium copper contacts with circular geometry. Operating temperature range is -55°C ~ 125°C, providing a 10°C lower minimum temperature limit compared to the original.

Frequently Asked Questions (FAQ)

Q: Can 1-215307-3 be used as a direct replacement for 68683-413?

A: Yes. Both connectors share identical mating pitch (0.100"), row configuration (2 rows, 0.100" spacing), position count (26), mounting type (through hole), and fastening mechanism (push-pull). The primary difference is contact finish material (gold vs. tin) and termination style (kinked pin vs. standard solder pin). Both maintain UL94 V-0 flammability rating.

Q: What is the impact of using gold-plated contacts instead of tin-plated contacts?

A: Gold plating provides enhanced corrosion resistance and improved contact reliability in high-humidity or corrosive environments. Both finishes are suitable for standard board-to-board applications. Gold plating is typically specified for applications requiring extended service life or exposure to environmental stress.

Q: Does the 0.320" insulation height of 6-534206-3 affect compatibility?

A: The increased insulation height of 6-534206-3 (0.320" vs. 0.276") may affect board layout and component spacing. Verify that the mating connector and surrounding components accommodate the taller profile before substitution.

Q: What is the significance of the 4.5A current rating on 803-43-026-10-001000?

A: The 803-43-026-10-001000 specifies a 4.5A current rating per contact, whereas the original 68683-413 does not specify a current rating. This indicates higher current-carrying capacity and may be advantageous for applications requiring increased power delivery through the connector interface.

Q: Are all substitute parts RoHS compliant?

A: The original 68683-413 is RoHS non-compliant. All three substitute parts (1-215307-3, 6-534206-3, and 803-43-026-10-001000) are ROHS3 compliant. If RoHS compliance is required for your application, any of the three substitutes is suitable.

Q: What is the difference between kinked pin and standard solder pin termination?

A: Kinked pin termination (used in 1-215307-3) provides mechanical retention and strain relief during solder reflow, reducing the risk of pin movement. Standard solder pin termination (used in 68683-413, 6-534206-3, and 803-43-026-10-001000) relies on solder joint strength alone. Both methods are industry-standard and suitable for through-hole assembly.
