Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX3313CUB is determined by strict parametric matching across the following critical criteria:

• Protocol: RS232 full-duplex transceiver
• Driver/Receiver Configuration: 1/1
• Data Rate: 460 Kbps
• Supply Voltage Range: 4.5V ~ 5.5V
• Operating Temperature Range: 0°C ~ 70°C
• Package Type: 10-TFSOP, 10-MSOP (0.118", 3.00mm Width)
• Receiver Hysteresis: 500 mV
• Mounting Type: Surface Mount

All substitute parts listed below meet these parametric requirements without deviation. Substitution is based solely on electrical and mechanical compatibility as defined by these parameters.

Parameter Comparison

Engineering Selection Recommendations

The MAX3313CUB is obsolete and no longer in active production. All four substitute parts listed above are active products with identical electrical and mechanical specifications. Selection among the active alternatives should be based on the following factors:

Product Status: All substitute parts are active products, ensuring long-term availability and supply chain continuity compared to the obsolete MAX3313CUB.

RoHS Compliance: All substitute parts are RoHS3 compliant, whereas the original MAX3313CUB is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements, any of the four active substitutes satisfy compliance mandates.

Packaging: All substitutes are supplied in tube packaging, providing standard handling and storage conditions for surface-mount components.

Inventory Availability: MAX3313ECUB+ offers the highest inventory level at 23,754 pieces, followed by MAX3311CUB+ at 3,100 pieces, MAX3313CUB+ at 2,160 pieces, and MAX3311ECUB+ at 2,250 pieces.

Frequently Asked Questions (FAQ)

Q: Can MAX3311CUB+ directly replace MAX3313CUB in existing designs?

A: Yes. Both parts share identical electrical parameters (RS232 protocol, 1/1 driver/receiver configuration, 460 Kbps data rate, 4.5V–5.5V supply, 0°C–70°C operating range) and mechanical specifications (10-TFSOP, 10-MSOP package). Pin-to-pin compatibility is maintained.

Q: What is the difference between MAX3313CUB+ and MAX3313ECUB+?

A: Both parts are parametrically identical. The primary difference is product designation and inventory availability. MAX3313ECUB+ has significantly higher stock levels (23,754 pieces versus 2,160 pieces).

Q: Are there any differences between MAX3311 and MAX3313 base product numbers?

A: Within the provided parameters, both base product numbers meet all substitution criteria. Selection between MAX3311 and MAX3313 variants should be based on design requirements and availability.

Q: Does the "+" suffix indicate a packaging or specification change?

A: The "+" suffix indicates tube packaging and active product status. The original MAX3313CUB without the "+" suffix is obsolete and supplied in different packaging.

Q: Are all substitutes RoHS compliant?

A: Yes. All four active substitute parts are RoHS3 compliant, whereas the original MAX3313CUB is RoHS non-compliant.

Q: Can these parts be used interchangeably in production?

A: Yes, provided the design accommodates the 10-TFSOP or 10-MSOP package format and the 4.5V–5.5V supply voltage range. All electrical and mechanical parameters are identical across all listed substitutes.
