Substitute Part Grouping Explanation

Substitute parts for the CSR0805JKR620 are qualified based on the following criteria:

Electrical Equivalence: Resistance value of 620 mOhms, power rating of 0.25W, and thick film composition must be maintained. Temperature coefficient of ±200ppm/°C and operating temperature range of -55°C ~ 155°C define the thermal performance envelope.

Mechanical Compatibility: Package type 0805 (2012 Metric) with identical footprint dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) and maximum seated height of 0.026" (0.65mm) ensures direct PCB compatibility without layout modifications.

Functional Requirements: Current sense application designation and thick film construction are preserved across all substitutes.

Compliance & Regulatory: RoHS3 compliance, MSL Level 1 rating, and REACH unaffected status must be maintained for supply chain and environmental requirements.

Tolerance variations (±5% vs ±1%) represent upgrade paths where tighter tolerance specifications are required, provided all other parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitute (RLP73K2AR62JTD): This part provides electrical and mechanical equivalence to the CSR0805JKR620 with identical tolerance specification (±5%). Both parts maintain Active product status with full RoHS3 compliance and MSL Level 1 rating. Selection between these two parts is based on supply availability and procurement lead times, as all functional and compliance parameters are equivalent.

Upgrade Substitute (RLP73K2AR62FTDF): This part offers improved tolerance specification (±1% vs ±5%) while maintaining all other electrical and mechanical parameters. The tighter tolerance reduces resistance value variation in current sense applications, providing enhanced measurement accuracy. This upgrade path is applicable when circuit design requires improved precision without modifying PCB layout or thermal characteristics. RoHS3 compliance and MSL Level 1 rating are preserved.

All substitute parts maintain Active product status and full regulatory compliance, ensuring compatibility with existing supply chain and quality requirements.

Frequently Asked Questions (FAQ)

Q: Can RLP73K2AR62JTD be used as a direct replacement for CSR0805JKR620?

A: Yes. Both parts share identical electrical specifications (620 mOhms ±5%, 0.25W), package footprint (0805 / 2012 Metric), and compliance certifications (RoHS3, MSL Level 1). No circuit modifications or PCB layout changes are required.

Q: What is the difference between RLP73K2AR62JTD and RLP73K2AR62FTDF?

A: The primary difference is tolerance specification. RLP73K2AR62JTD maintains ±5% tolerance matching the original part, while RLP73K2AR62FTDF provides ±1% tolerance for improved measurement precision. All other parameters including resistance value, power rating, package dimensions, and operating temperature range are identical.

Q: When should the upgrade part RLP73K2AR62FTDF be selected?

A: The upgrade part is selected when circuit design requires tighter tolerance control for current sense measurement accuracy. The ±1% tolerance reduces resistance variation compared to ±5%, improving measurement precision without affecting thermal performance or package compatibility.

Q: Are all substitute parts compatible with the same PCB layout?

A: Yes. All parts use identical 0805 (2012 Metric) package with matching footprint dimensions (0.079" L x 0.049" W) and maximum seated height (0.026"). No PCB modifications are necessary for substitution.

Q: Do substitute parts maintain the same operating temperature range?

A: Yes. All parts operate across -55°C ~ 155°C with identical temperature coefficient of ±200ppm/°C, ensuring equivalent thermal performance in the application.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. CSR0805JKR620, RLP73K2AR62JTD, and RLP73K2AR62FTDF all maintain ROHS3 compliance with MSL Level 1 (Unlimited) rating, meeting environmental and regulatory requirements.
