TRS202IPWR RS232 Transceiver Equivalent & Substitute Parts

Part Overview

The TRS202IPWR is a 2/2 full-duplex RS232 transceiver manufactured by Texas Instruments in a 16-TSSOP surface mount package. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The TRS202IPWR operates within a 4.5V to 5.5V supply voltage range with a 120 kbps data rate and 500 mV receiver hysteresis, suitable for legacy RS232 communication applications requiring full transceiver functionality.

Substitute Part Grouping Explanation

Substitution of the TRS202IPWR is determined by strict equivalence across the following critical parameters: RS232 protocol compliance, 2/2 driver/receiver configuration, full-duplex operation, 16-TSSOP package geometry, surface mount mounting type, 4.5V to 5.5V supply voltage range, and -40°C to 85°C operating temperature range. Parts meeting these core electrical and mechanical specifications are classified as direct parametric equivalents. Parts with identical specifications but different packaging formats (Cut Tape vs. Tape & Reel) are considered packaging variants of the same base product. Parts with enhanced specifications (higher data rate or receiver hysteresis) from the same manufacturer family are listed as manufacturer-recommended alternatives where supply constraints exist.

Engineering Selection Recommendations

For applications requiring full parameter equivalence with the obsolete TRS202IPWR, select TRS202EIPWR (active status, Tape & Reel packaging, 15704 units in stock) or MAX202IPWR (active status, Cut Tape packaging, 1420 units in stock). Both parts maintain identical electrical specifications: 120 kbps data rate, 500 mV receiver hysteresis, and -40°C to 85°C operating temperature range.

For applications where extended operating temperature range is not required, MAX202ECUE+T (active status, 19524 units in stock) provides the highest inventory availability with 0°C to 70°C operating temperature specification and Tape & Reel packaging.

For applications tolerating enhanced data rate and receiver hysteresis specifications, ADM202EARUZ-REEL7 (active status, 2400 units in stock) offers 230 kbps data rate and 650 mV receiver hysteresis with Cut Tape packaging, or ADM202EARUZ-REEL (active status, 1922 units in stock) with Tape & Reel packaging.

All recommended parts maintain ROHS3 compliance, MSL 1 (Unlimited) moisture sensitivity rating, and identical 16-TSSOP package geometry. Selection should prioritize active product status parts to ensure long-term supply continuity.

Frequently Asked Questions (FAQ)

Q: Can MAX202ECUE+T replace TRS202IPWR in all applications?

A: MAX202ECUE+T is electrically equivalent for data rate (120 kbps) and receiver hysteresis (500 mV) specifications. However, its operating temperature range is 0°C to 70°C, compared to TRS202IPWR's -40°C to 85°C. Use MAX202ECUE+T only in applications operating within 0°C to 70°C. For full temperature range equivalence, use TRS202EIPWR or MAX202IPWR.

Q: What is the difference between TRS202EIPWR and MAX202IPWR?

A: Both parts are parametric equivalents with identical electrical specifications (120 kbps, 500 mV hysteresis, -40°C to 85°C). TRS202EIPWR is manufactured by Texas Instruments with Tape & Reel packaging (15704 units available). MAX202IPWR is manufactured by Texas Instruments with Cut Tape packaging (1420 units available). Selection depends on packaging format requirements and inventory availability.

Q: Are ADM202EARUZ variants suitable replacements?

A: ADM202EARUZ variants (ADM202EARUZ, ADM202EARUZ-REEL, ADM202EARUZ-REEL7) have enhanced specifications: 230 kbps data rate and 650 mV receiver hysteresis, compared to TRS202IPWR's 120 kbps and 500 mV. These parts are backward compatible in applications designed for TRS202IPWR specifications. Use ADM202 variants only if the application can tolerate higher data rate and hysteresis values, or if supply constraints require it.

Q: What packaging options are available?

A: Substitute parts are available in three packaging formats: Cut Tape (CT) & Digi-Reel® (TRS202IPWR, MAX202IPWR, ADM202EARUZ-REEL7), Tube (TRS202EIPW, MAX202EEUE+, ADM202EARUZ, MAX202CUE+, MAX202ECUE+), and Tape & Reel (TR) (TRS202EIPWR, ADM202EARUZ-REEL, MAX202ECUE+T). Select based on assembly process requirements and minimum order quantities.

Q: Why is TRS202IPWR marked as obsolete?

A: TRS202IPWR is classified as obsolete by Texas Instruments. Active equivalent parts (TRS202EIPWR, MAX202IPWR, MAX202EEUE+) ensure long-term design support and supply continuity. Transition to active parts is recommended for new designs and ongoing production.
