Key Parameters

Substitute Part Grouping Explanation

Substitute parts are identified strictly by matching the primary electrical and mechanical parameters: resistance value, tolerance, power rating, composition, temperature coefficient, package/case, operating temperature, physical dimensions, number of terminations, and moisture sensitivity level. All substitutes presented meet these parameters exactly.

Parameter Comparison

Engineering Selection Recommendations

CRCW0201390KFNED (Vishay Dale) is Active and matches all stated parameters, providing a suitable substitute based strictly on product status and compliance. RK73H1HTTC3903F (KOA Speer Electronics, Inc.) fulfills all corresponding parameters but is listed as Not For New Designs, which should be considered when selecting for new projects. Both substitutes are ROHS3 compliant and REACH unaffected.

Frequently Asked Questions (FAQ)

Q1: What are the required electrical parameters for valid substitution?
A1: Key parameters for substitution are resistance (390 kOhms), tolerance (±1%), power rating (0.05W, 1/20W), composition (Thick Film), and temperature coefficient (±200ppm/°C).

Q2: Is the package/case size critical for equivalent selection?
A2: Yes. All substitutes must match the 0201 (0603 Metric) package size and dimensions to ensure mechanical compatibility.

Q3: Are there differences in compliance or product status among substitutes?
A3: CRCW0201390KFNED is Active; RK73H1HTTC3903F is Not For New Designs. Both substitutes are ROHS3 compliant and have MSL 1 (Unlimited).

Q4: Can substitutes be used interchangeably in existing designs?
A4: Substitutes matching all specified electrical and mechanical parameters, as listed, can be directly interchanged according to the provided criteria.

Q5: Is moisture sensitivity relevant for selection?
A5: All referenced substitutes have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), matching the main part and fulfilling this selection criterion.
