Key Parameters

Substitute Part Grouping Explanation

Substitution for the CSR2010JTR300 is determined by the following criteria:

Electrical Parameters: Resistance value (300 mOhms), power rating (1W), and composition (Thick Film) must remain constant. Tolerance and temperature coefficient variations are permitted within the scope of direct substitution.

Mechanical Parameters: Package type (2010 / 5025 Metric) and termination count (2) must match exactly.

Compliance Parameters: RoHS3 compliance and MSL rating (1) must be maintained.

Direct Substitutes: Parts with identical electrical and mechanical specifications but different tolerance or temperature coefficient ratings.

Upgrade Substitutes: Parts with improved tolerance specifications (±1% vs ±5%) while maintaining all other core parameters.

Parameter Comparison

Engineering Selection Recommendations

CSR2010JTR300 (Original Part): Use when ±5% tolerance and ±100ppm/°C temperature coefficient are specified in circuit design. All parts are Active status with ROHS3 compliance and unlimited moisture sensitivity rating.

CSRN2010JTR300 (Direct Substitute): Functionally equivalent with identical tolerance (±5%) and power rating (1W). Temperature coefficient is ±250ppm/°C compared to ±100ppm/°C in the original. Physical dimensions vary slightly (width 2.45mm vs 2.54mm, height 0.75mm vs 0.65mm). Select when dimensional variation is acceptable and temperature coefficient drift tolerance permits the higher specification.

CSR2010FKR300 (Upgrade Substitute): Provides improved tolerance specification (±1% vs ±5%) with identical temperature coefficient (±100ppm/°C) and physical dimensions to the original part. Select for applications requiring tighter resistance tolerance while maintaining all other electrical and mechanical characteristics.

Frequently Asked Questions (FAQ)

Q: Can CSRN2010JTR300 replace CSR2010JTR300 in all applications?

A: CSRN2010JTR300 maintains identical resistance, tolerance, and power rating. However, temperature coefficient is ±250ppm/°C versus ±100ppm/°C, and physical dimensions differ slightly (width and height). Verify circuit design permits these variations before substitution.

Q: What is the primary advantage of CSR2010FKR300 over CSR2010JTR300?

A: CSR2010FKR300 provides ±1% tolerance compared to ±5% tolerance in CSR2010JTR300. Temperature coefficient, power rating, package, and physical dimensions remain identical. Select CSR2010FKR300 when circuit specifications require tighter resistance accuracy.

Q: Are all three parts mechanically compatible with 2010 package footprints?

A: All three parts use 2010 (5025 Metric) package with 2 terminations. CSR2010JTR300 and CSR2010FKR300 share identical dimensions (0.197" L x 0.100" W, 0.026" height). CSRN2010JTR300 has slightly different width (0.097" vs 0.100") and height (0.030" vs 0.026"). Verify PCB layout tolerances accommodate CSRN2010JTR300 dimensional variation if substituting.

Q: Do all substitute parts maintain ROHS3 compliance?

A: Yes. CSR2010JTR300, CSRN2010JTR300, and CSR2010FKR300 are all ROHS3 compliant with MSL rating 1 (Unlimited).

Q: Which part should be selected for high-temperature stability applications?

A: CSR2010JTR300 and CSR2010FKR300 both specify ±100ppm/°C temperature coefficient. CSRN2010JTR300 specifies ±250ppm/°C. For applications requiring minimal temperature-induced resistance drift, select CSR2010JTR300 or CSR2010FKR300.
