Substitute Part Grouping Explanation

Substitution for the A24-LCG-T-R is determined by strict adherence to the following parameters:

24-position DIP configuration with 0.6" (15.24mm) row spacing
0.100" (2.54mm) pitch for both mating and post contacts
Through-hole solder termination
Gold contact finish on mating surface
UL94 V-0 flammability rating
Operating temperature range compatibility
Current rating of 1 A or higher
Contact resistance of 30mOhm or lower

Three substitute parts meet these criteria with variations in contact material, housing composition, and extended temperature or current capabilities.

Engineering Selection Recommendations

A 24-LC-TT (Assmann WSW Components): This substitute maintains identical electrical specifications (1 A current rating, 30mOhm contact resistance) and shares the same manufacturer as the main part. The primary difference is tin-plated mating contacts instead of gold, and a reduced upper operating temperature limit of 85°C. This part is suitable for applications operating below 85°C where tin contact finish is acceptable. Active product status ensures ongoing availability.

SA246040 (On Shore Technology Inc.): This substitute provides enhanced electrical performance with 3 A current rating and 4mOhm contact resistance, both superior to the main part. Gold contact finish matches the original specification. Operating temperature range (-40°C to 105°C) covers the main part's range. Active product status and ROHS3 compliance support long-term supply chain stability.

110-13-624-41-001000 (Mill-Max Manufacturing Corp.): This substitute offers the widest operating temperature range (-55°C to 125°C) and highest current rating (3 A). Gold contact finish aligns with the original specification. Active product status and ROHS3 compliance ensure availability. Contact resistance is not specified in the provided data.

All three substitutes maintain the critical 24-position DIP configuration, 0.6" row spacing, 0.100" pitch, through-hole solder termination, and UL94 V-0 flammability rating required for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can A 24-LC-TT replace A24-LCG-T-R in all applications?

A: A 24-LC-TT is compatible for applications operating at or below 85°C. The main part supports -55°C to 105°C, so applications requiring operation above 85°C require SA246040 or 110-13-624-41-001000 instead.

Q: What is the difference between gold and tin contact finishes?

A: Both finishes provide electrical conductivity and solder compatibility. Gold offers superior corrosion resistance and lower contact resistance. Tin is cost-effective and suitable for standard applications. A 24-LC-TT uses tin; the other substitutes use gold matching the original A24-LCG-T-R specification.

Q: Are all substitutes RoHS compliant?

A: SA246040 and 110-13-624-41-001000 are ROHS3 compliant. A 24-LC-TT is ROHS3 compliant. RoHS compliance status for the original A24-LCG-T-R is not specified in the provided data.

Q: Which substitute offers the best electrical performance?

A: SA246040 and 110-13-624-41-001000 both provide 3 A current rating compared to 1 A for the main part. SA246040 specifies 4mOhm contact resistance, superior to the main part's 30mOhm.

Q: Can these substitutes be used interchangeably on the same PCB?

A: Yes. All substitutes maintain identical 24-position DIP configuration, 0.6" row spacing, 0.100" pitch, and through-hole solder termination, ensuring mechanical and electrical compatibility on PCBs designed for the A24-LCG-T-R.

Q: What is the inventory status of these substitutes?

A: A 24-LC-TT has 6750 units in stock. SA246040 has 1319 units. 110-13-624-41-001000 has 1135 units. All are available as new original stock.
