Equivalent & Substitute Parts Reference for RMC1/16SK3003DTH

Part Overview

The Kamaya RMC1/16SK3003DTH is a 300 kOhms ±0.5% thick film chip resistor rated at 0.1W (1/10W), housed in a 0402 (1005 Metric) package. The product is active and available in Tape & Reel packaging. Identifying suitable equivalent or substitute models is critical when original inventory levels are insufficient or if specific compliance or feature requirements must be met for the application, such as automotive ratings or moisture sensitivity.

Substitute Part Grouping Explanation

Substitutes are identified strictly based on parametric equivalence. The allowed substitution requires matching the following mandatory parameters: resistance value, tolerance, power rating, composition, temperature coefficient, operating temperature range, package/case size, number of terminations, moisture sensitivity level (MSL), and product status. Compliance standards and packaging must also match when relevant.

Engineering Selection Recommendations

Both RMC1/16SK3003DTH and RK73H1ETTP3003D are active products with 300 kOhms resistance, ±0.5% tolerance, 0.1W power rating, 0402 package size, and moisture sensitivity level 1 (Unlimited). RK73H1ETTP3003D also complies with ROHS3 and REACH standards and is AEC-Q200 rated for automotive applications. Selection between these models can be guided by the desired compliance and application environment, provided that all parametric and packaging criteria are met.

Frequently Asked Questions (FAQ)

Q1: What parameters must match for substituting a chip resistor in the 0402 package?
A1: Substitution is permitted when resistance value, tolerance, power rating, temperature coefficient, composition, package/case size, number of terminations, operating temperature range, moisture sensitivity level (MSL), and part status are identical.

Q2: Are RMC1/16SK3003DTH and RK73H1ETTP3003D compatible for use on the same PCB footprint?
A2: Both parts use the 0402 (1005 Metric) package and share identical package dimensions and terminations, enabling direct footprint compatibility.

Q3: Is AEC-Q200 rating necessary for general electronics assemblies?
A3: The AEC-Q200 rating is not mandatory unless specified by the end application, such as automotive reliability requirements.

Q4: Can differences in manufacturer impact parametric compatibility?
A4: Manufacturer origin does not affect parametric compatibility as long as the key substitution parameters are strictly matched.

Q5: What is the importance of Moisture Sensitivity Level (MSL) in selecting substitute resistors?
A5: Identical MSL ensures consistent assembly, handling, and storage procedures for both original and substitute parts.
