Key Parameters

Substitute Part Grouping Explanation

Substitution for the LVC25JR820EV is determined by the following critical parameters: resistance value (820 mOhms), package type (2512), composition (thick film), and RoHS3 compliance. The substitute parts are grouped based on tolerance and power rating variations while maintaining electrical and mechanical compatibility.

Key substitution criteria:

• Resistance: 820 mOhms (exact match required)
• Package: 2512 (6432 Metric) (exact match required)
• Composition: Thick film (exact match required)
• RoHS3 Compliance: Required
• Tolerance: ±1% or ±5% acceptable
• Power Rating: 1W or 2W acceptable (2W provides margin)
• Temperature Coefficient: ±100ppm/°C (standard for all candidates)

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain full electrical and mechanical compatibility with the LVC25JR820EV. Selection among substitutes depends on specific design requirements:

RCWE2512R820FKEA (Vishay Dale): Offers improved tolerance (±1%) and increased power rating (2W) with automotive AEC-Q200 qualification. Extended operating temperature range (-55°C to 155°C) provides margin beyond the original specification. Suitable for applications requiring higher reliability and automotive compliance.

RHC2512JTR820 (Stackpole Electronics Inc): Maintains ±5% tolerance matching the original part while providing 2W power rating. Extended temperature range and active product status ensure long-term availability. Recommended for direct replacement where tolerance and power margin are acceptable.

RL73H3AR82FTDF (TE Connectivity Passive Product): Provides ±1% tolerance with 1W power rating matching the original specification. Active product status with extended temperature range. Suitable for applications requiring improved tolerance without power rating increase.

RL73H3AR82FTE (TE Connectivity Passive Product): Identical electrical specifications to RL73H3AR82FTDF with higher inventory availability (20,728 pcs). Preferred choice for ±1% tolerance requirement with 1W power rating and extended temperature range.

Frequently Asked Questions (FAQ)

Q: Can I use a 2W rated resistor as a substitute for the 1W LVC25JR820EV? A: Yes. The 2W rated substitutes (RCWE2512R820FKEA and RHC2512JTR820) are mechanically and electrically compatible. Higher power rating provides additional thermal margin and does not negatively impact circuit performance.

Q: What is the difference between ±1% and ±5% tolerance substitutes? A: Tolerance specifies the maximum deviation from the nominal 820 mOhms resistance value. ±1% tolerance (RCWE2512R820FKEA, RL73H3AR82FTDF, RL73H3AR82FTE) provides tighter resistance control suitable for precision current sensing. ±5% tolerance (RHC2512JTR820) matches the original specification and is acceptable for general current sense applications.

Q: Are all substitutes compatible with the 2512 package footprint? A: Yes. All substitute parts use the 2512 (6432 Metric) package with identical termination count (2). Physical dimensions are within tolerance for standard PCB footprints designed for 2512 resistors.

Q: Why do some substitutes have extended operating temperature ranges? A: Substitute parts from active manufacturers (Vishay Dale, Stackpole Electronics Inc, TE Connectivity) are designed to broader industrial specifications. Extended ranges (-55°C to 155°C versus -40°C to 125°C) provide additional design margin and are backward compatible with the original specification.

Q: Which substitute offers the best long-term availability? A: RL73H3AR82FTE (TE Connectivity) has the highest current inventory (20,728 pcs) and active product status, ensuring sustained availability for production requirements.

Q: Are all substitutes RoHS3 compliant? A: Yes. All substitute parts and the original LVC25JR820EV are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), meeting environmental and regulatory requirements.
