Key Parameters

Substitute Part Grouping Explanation

Substitution for the LVC25FR200EV is determined by the following critical parameters: resistance value (200 mOhms), tolerance (±1%), package type (2512), composition (thick film), and compliance certifications (ROHS3). The substitute parts are grouped based on power rating capability and product status.

Group 1: Active Direct Substitutes (1W Rating)

• RL73H3AR20FTE and RL73H3AR20FTDF maintain the original 1W power rating with identical resistance and tolerance specifications
• Both are manufactured by TE Connectivity Passive Product and carry active product status
• Operating temperature range extends to -55°C ~ 155°C, providing broader thermal coverage than the original part

Group 2: Higher Power Capability Substitute (2W Rating)

• RHC2512FTR200 provides increased power handling at 2W while maintaining 200 mOhms resistance and ±1% tolerance
• Manufactured by Stackpole Electronics Inc with active product status
• Suitable for applications requiring enhanced thermal performance within the same package footprint

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Equivalent Performance): RL73H3AR20FTE and RL73H3AR20FTDF are preferred substitutes. Both maintain the 1W power rating and current sense functionality of the original LVC25FR200EV while offering active product status and extended operating temperature range (-55°C ~ 155°C). These parts are electrically and mechanically compatible with existing designs without modification.

For Enhanced Thermal Performance: RHC2512FTR200 is suitable when design margins require increased power dissipation capability. The 2W rating provides thermal headroom within the identical 2512 package footprint. This substitute is appropriate for applications experiencing higher ambient temperatures or increased current stress.

All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can RL73H3AR20FTE directly replace LVC25FR200EV in existing designs? A: Yes. Both parts share identical resistance (200 mOhms), tolerance (±1%), power rating (1W), package (2512), and composition (thick film). The RL73H3AR20FTE has extended operating temperature range and active product status, making it a direct functional equivalent.

Q: What is the difference between RL73H3AR20FTE and RL73H3AR20FTDF? A: Both are TE Connectivity RL73 series 200 mOhms 1W 2512 resistors with identical electrical specifications. The difference lies in packaging designation (FTE vs FTDF), which may reflect different tape and reel configurations or internal product variants. Electrical performance and mechanical compatibility are equivalent.

Q: When should RHC2512FTR200 be selected instead of the 1W alternatives? A: RHC2512FTR200 should be selected when the application requires higher power dissipation capability or operates at elevated ambient temperatures. The 2W rating provides additional thermal margin while maintaining the same package size and resistance value. Verify that the circuit design can accommodate the potentially different thermal characteristics of the higher-rated component.

Q: Are all substitute parts RoHS3 compliant? A: Yes. LVC25FR200EV, RL73H3AR20FTE, RL73H3AR20FTDF, and RHC2512FTR200 are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the impact of the extended operating temperature range in substitute parts? A: The substitute parts (RL73 and RHC series) operate from -55°C to 155°C compared to the original -40°C to 125°C range. This provides broader thermal coverage and is beneficial for applications in extreme environments. There is no negative impact for designs operating within the original temperature range.

Q: Are there any dimensional differences between the original and substitute parts? A: All parts use the 2512 (6432 Metric) package with minor dimensional variations within standard tolerances. Height-seated maximum ranges from 0.026" to 0.028" (0.65mm to 0.70mm). These variations are within typical PCB design tolerances and do not affect mechanical compatibility or assembly processes.
