AS6C1008-55STINL Equivalent & Substitute Parts

Part Overview

The AS6C1008-55STINL is a 1Mbit asynchronous SRAM memory IC manufactured by Alliance Memory, Inc. This parallel interface memory device operates across a wide voltage range (2.7V to 5.5V) and is housed in a 32-sTSOP surface mount package. The part maintains active product status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified when electrical specifications, memory organization, interface type, and package configuration remain identical to the primary part number.

Engineering Selection Recommendations

Both the AS6C1008-55STINL and AS6C1008-55STIN maintain active product status with identical compliance certifications. The AS6C1008-55STIN is designated as the manufacturer recommended substitute and carries significantly higher inventory availability (33,630 pcs vs. 1,088 pcs). Selection between these parts should be based on supply chain requirements and lead time considerations, as all electrical, mechanical, and regulatory specifications are equivalent.

Frequently Asked Questions (FAQ)

Q: Can AS6C1008-55STIN replace AS6C1008-55STINL in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including memory capacity, timing characteristics, voltage range, temperature range, and package configuration.

Q: Are there differences in the package or pin configuration?

A: No. Both parts use the identical 32-sTSOP surface mount package with 0.465" width (11.80mm). Pin configuration and mechanical dimensions are equivalent.

Q: What is the significance of the different part number suffixes?

A: The suffix variation reflects different packaging or distribution channels from Alliance Memory, Inc., but does not indicate functional or electrical differences. All core specifications remain identical.

Q: Are both parts RoHS3 compliant?

A: Yes. Both AS6C1008-55STINL and AS6C1008-55STIN carry ROHS3 compliance certification and are REACH unaffected.

Q: What is the MSL rating and why is it important?

A: Both parts carry MSL 3 rating (168 hours maximum floor life). This moisture sensitivity level must be observed during storage and handling to maintain component reliability.

Q: Which part should be selected for new designs?

A: Selection should be based on supply availability and procurement lead times. The AS6C1008-55STIN offers higher inventory levels and is the manufacturer recommended option. Both parts are functionally equivalent for design purposes.
