• Power rating: 0.25W minimum (0.5W is acceptable as upgrade)
• Temperature coefficient: ±200ppm/°C or better
• Operating temperature range: -55°C to 155°C minimum

Mechanical Parameters (Must Match):

• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Number of terminations: 2
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)

Compliance Parameters:

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The identified substitutes meet or exceed all electrical specifications while maintaining identical mechanical compatibility and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

CSR0805JK47L0 (Primary Part): Select this part for applications requiring standard tolerance (±5%) current sense resistors without automotive qualification requirements. Suitable for general industrial and consumer applications within the specified temperature range.

ERJ-6BWJR047V (Substitute - Matched Tolerance): This Panasonic part maintains ±5% tolerance matching the original specification while providing doubled power rating (0.5W vs 0.25W). Includes AEC-Q200 automotive qualification, enabling use in automotive applications. Temperature coefficient and operating range are equivalent. Height increase of 0.004" (0.10mm) must be verified for PCB layout compatibility.

ERJ-6BWFR047V (Substitute - Enhanced Tolerance): This Panasonic part upgrades tolerance to ±1% while maintaining 0.5W power rating and AEC-Q200 automotive qualification. Provides superior accuracy for precision current sensing applications. Height and thermal characteristics are equivalent to ERJ-6BWJR047V. Select when tighter tolerance specification is required.

All substitutes maintain ROHS3 compliance, MSL Level 1 rating, and identical package footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can ERJ-6BWJR047V or ERJ-6BWFR047V be used as direct replacements for CSR0805JK47L0?

A: Yes, both parts are mechanically and electrically compatible. The 0805 package footprint is identical. Verify PCB layout clearance for the maximum seated height of 0.030" (0.75mm) versus the original 0.026" (0.65mm).

Q: What is the difference between ERJ-6BWJR047V and ERJ-6BWFR047V?

A: Both parts are identical except for tolerance specification. ERJ-6BWJR047V maintains ±5% tolerance matching the original part. ERJ-6BWFR047V provides ±1% tolerance for applications requiring higher accuracy. Power rating and all other parameters are equivalent.

Q: Are the Panasonic substitutes suitable for automotive applications?

A: Yes, both ERJ-6BWJR047V and ERJ-6BWFR047V carry AEC-Q200 automotive qualification. The original CSR0805JK47L0 does not include this certification.

Q: Does the increased power rating (0.5W vs 0.25W) affect circuit performance?

A: No. Higher power rating indicates greater thermal capability and does not alter electrical characteristics. Resistance, tolerance, and temperature coefficient remain functionally equivalent.

Q: Are there height restrictions for using the substitute parts?

A: The substitute parts have a maximum seated height of 0.030" (0.75mm) compared to 0.026" (0.65mm) for the original. Verify PCB layout and component clearance requirements before substitution.

Q: Do all parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, MSL Level 1, and operate across -55°C to 155°C. REACH status is unaffected for all parts.
