Key Parameters

Substitute Part Grouping Explanation

Substitution for the LVC25FR220EV is determined by strict equivalence across the following parameters: resistance value (220 mOhms), tolerance (±1%), package type (2512), composition (thick film), and moisture sensitivity level (MSL 1). The operating temperature range and power rating establish functional boundaries for direct replacement.

Four substitute parts meet these core electrical and mechanical criteria:

Direct Equivalents (1W, Current Sense): RL73H3AR22FTE and RL73H3AR22FTDF from TE Connectivity maintain identical electrical specifications with extended operating temperature ranges (-55°C ~ 155°C) and active product status.

Upgrade Option (1W, Automotive Qualified): PT2512FK-070R22L from YAGEO provides automotive AEC-Q200 qualification with improved temperature coefficient (±75ppm/°C) and active availability.

Higher Power Alternative (2W): RHC2512FTR220 from Stackpole Electronics Inc offers increased power dissipation (2W) while maintaining all other core parameters, suitable for applications requiring additional thermal margin.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: RL73H3AR22FTE is the primary substitute, offering identical electrical performance with active product status and ROHS3 compliance. Extended operating temperature range (-55°C ~ 155°C) provides additional margin beyond the original specification.

For RoHS-Compliant Applications: PT2512FK-070R22L or RL73H3AR22FTE are required. RL73H3AR22FTDF is not suitable for RoHS-compliant designs due to non-compliant status.

For Automotive Applications: PT2512FK-070R22L is the only substitute with AEC-Q200 qualification, meeting automotive reliability standards with improved temperature coefficient performance.

For Increased Power Dissipation: RHC2512FTR220 provides 2W rating while maintaining all other core parameters, suitable for applications requiring additional thermal headroom within the 2512 package envelope.

For Production Continuity: All active substitutes (RL73H3AR22FTE, PT2512FK-070R22L, RHC2512FTR220) have confirmed inventory availability, ensuring supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can RL73H3AR22FTE directly replace LVC25FR220EV? A: Yes. Both parts share identical resistance (220 mOhms), tolerance (±1%), power rating (1W), package (2512), composition (thick film), and MSL rating (1). RL73H3AR22FTE has active product status and extended operating temperature range.

Q: What is the difference between RL73H3AR22FTE and RL73H3AR22FTDF? A: Both are TE Connectivity RL73 series with identical electrical specifications. The primary difference is RoHS compliance: RL73H3AR22FTE is ROHS3 compliant, while RL73H3AR22FTDF is RoHS non-compliant. For new designs, RL73H3AR22FTE is recommended.

Q: Why is PT2512FK-070R22L listed as an upgrade option? A: PT2512FK-070R22L includes AEC-Q200 automotive qualification and features a lower temperature coefficient (±75ppm/°C) compared to the original ±100ppm/°C specification, providing improved stability in automotive applications.

Q: Can RHC2512FTR220 be used as a direct substitute? A: RHC2512FTR220 is electrically compatible but rated for 2W power dissipation versus the original 1W. It is suitable for applications requiring higher power handling within the same 2512 package footprint. Verify circuit design allows the increased power rating.

Q: Are all substitutes available in tape and reel packaging? A: RL73H3AR22FTE, RL73H3AR22FTDF, and RHC2512FTR220 are supplied in Tape & Reel (TR) packaging. PT2512FK-070R22L is available in Cut Tape (CT) & Digi-Reel® packaging. Confirm packaging requirements for your production process.

Q: Do all substitutes meet MSL 1 (Unlimited) moisture sensitivity? A: Yes. All substitute parts are rated MSL 1 (Unlimited), matching the original LVC25FR220EV specification and eliminating moisture sensitivity constraints for storage and handling.
