Key Parameters

Substitute Part Grouping Explanation

Substitution for the LVC25FR047EV is determined by the following critical parameters:

• Resistance Value: 47 mOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package / Case: 2512 (6432 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±200ppm/°C (exact match required)
• RoHS Compliance: ROHS3 Compliant (minimum requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All substitute parts listed maintain these core electrical and mechanical specifications. Differences in power rating, operating temperature range, and additional certifications (such as AEC-Q200) represent upgrades or enhanced feature sets while preserving functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

CSR2512FT47L0 (Stackpole Electronics Inc): This part provides a direct functional upgrade with doubled power rating (2W vs 1W) and extended operating temperature range (-55°C ~ 155°C vs -40°C ~ 125°C). Product status is active with full availability. Suitable for applications requiring enhanced thermal performance without automotive qualification requirements.

CSRN2512FK47L0 (Stackpole Electronics Inc): This part includes AEC-Q200 automotive qualification in addition to the performance upgrades of CSR2512FT47L0. Recommended for automotive and mission-critical applications where AEC-Q200 compliance is specified or required.

CSRN2512FT47L0 (Stackpole Electronics Inc): Manufacturer-recommended substitute with AEC-Q200 automotive qualification, extended operating temperature range, and active product status. This part represents the primary recommended replacement for the obsolete LVC25FR047EV, particularly for designs requiring automotive-grade reliability.

All substitute parts maintain identical electrical specifications (47 mOhms, ±1% tolerance, ±200ppm/°C temperature coefficient) and package compatibility (2512 / 6432 Metric) with the original part.

Frequently Asked Questions (FAQ)

Q: Can CSR2512FT47L0 be used as a direct replacement for LVC25FR047EV?

A: Yes. Both parts share identical resistance (47 mOhms), tolerance (±1%), package (2512), composition (thick film), and temperature coefficient (±200ppm/°C). The CSR2512FT47L0 provides higher power rating (2W vs 1W) and wider operating temperature range, making it functionally compatible and superior for thermal margin.

Q: What is the difference between CSR2512FT47L0 and CSRN2512FK47L0?

A: Both parts have identical electrical specifications and package. CSRN2512FK47L0 includes AEC-Q200 automotive qualification. Select CSRN2512FK47L0 for automotive applications; select CSR2512FT47L0 for general industrial applications.

Q: Why are the substitute parts rated at 2W instead of 1W?

A: The substitute parts from Stackpole Electronics Inc are designed with higher power dissipation capability. This upgrade does not affect electrical compatibility and provides additional thermal headroom for the same 47 mOhm resistance value in the identical 2512 package.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed are ROHS3 compliant, matching the compliance status of the original LVC25FR047EV.

Q: What is the significance of AEC-Q200 rating on CSRN series parts?

A: AEC-Q200 is an automotive qualification standard. CSRN2512FK47L0 and CSRN2512FT47L0 meet this standard for automotive applications. Use these parts when AEC-Q200 compliance is required; use CSR2512FT47L0 for non-automotive applications.

Q: Are there any dimensional differences between the main part and substitutes?

A: Dimensions are nominally equivalent across all parts in the 2512 package. Minor variations exist within tolerance: LVC25FR047EV is 0.250" L x 0.130" W with 0.026" max height; substitute parts range from 0.250-0.252" L x 0.124-0.126" W with 0.026-0.028" max height. These variations are within standard 2512 package specifications and do not affect PCB layout or assembly compatibility.
