Key Parameters

Substitute Part Grouping Explanation

Substitution for the LVC25FR033EV is determined by the following critical parameters:

• Resistance Value: 33 mOhms ±1% (exact match required)
• Package / Case: 2512 (6432 Metric) (physical and electrical compatibility)
• Tolerance: ±1% (electrical accuracy requirement)
• Composition: Thick Film (material consistency)
• Temperature Coefficient: ±200ppm/°C (thermal stability)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

All substitute parts listed maintain these core parameters. The primary difference among substitutes is the power rating upgrade from 1W to 2W, which provides enhanced thermal performance while maintaining backward compatibility. Automotive-grade variants (CSRN series) include AEC-Q200 certification for applications requiring automotive qualification.

Engineering Selection Recommendations

For Standard Applications: CSR2512FK33L0 and CSR2512FT33L0 are direct functional replacements for the LVC25FR033EV. Both parts are manufactured by Stackpole Electronics Inc and maintain active product status. The 2W power rating provides improved thermal margin compared to the original 1W specification. The extended operating temperature range (-55°C ~ 155°C) accommodates broader environmental conditions. Both variants are ROHS3 compliant and carry MSL 1 rating.

For Automotive Applications: CSRN2512FK33L0 and CSRN2512FT33L0 are specified for applications requiring automotive-grade components. These parts carry AEC-Q200 certification and are suitable for automotive current sense applications. The CSRN series maintains all electrical and thermal specifications while meeting automotive qualification standards.

Product Status Consideration: All substitute parts carry active product status, ensuring long-term availability and supply chain stability compared to the obsolete LVC25FR033EV.

Frequently Asked Questions (FAQ)

Q: Can CSR2512FK33L0 or CSR2512FT33L0 directly replace LVC25FR033EV in existing designs? A: Yes. Both parts maintain identical resistance value (33 mOhms ±1%), tolerance (±1%), package (2512), composition (thick film), and temperature coefficient (±200ppm/°C). The 2W power rating is a functional upgrade that does not affect compatibility.

Q: What is the difference between CSR2512FK33L0 and CSR2512FT33L0? A: Both parts are electrically and mechanically identical. The difference lies in packaging designation within the Stackpole CSR series. Both are available in Tape & Reel (TR) packaging and maintain the same electrical specifications.

Q: When should CSRN2512FK33L0 or CSRN2512FT33L0 be selected? A: Select CSRN variants when the application requires automotive qualification. These parts carry AEC-Q200 certification and are designed for automotive current sense applications. Electrical specifications remain identical to CSR variants.

Q: Does the 2W power rating change thermal behavior in the circuit? A: The 2W rating indicates increased power dissipation capability. In applications where the original 1W part operated near its thermal limit, the 2W substitute provides improved thermal margin and reliability.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitutes (CSR2512FK33L0, CSR2512FT33L0, CSRN2512FK33L0, CSRN2512FT33L0) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level.

Q: What is the operating temperature range difference? A: The LVC25FR033EV operates from -40°C to 125°C. All Stackpole substitutes extend this range to -55°C to 155°C, providing broader environmental coverage without affecting electrical performance within the original specification range.
