Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MF1/4DC9091F is determined by strict equivalence across the following critical parameters: resistance value (9.09 kOhms), tolerance (±1%), power rating (0.25W), composition (metal film), package type (axial), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and automotive qualification (AEC-Q200). The identified substitute part maintains identical electrical and mechanical specifications while differing only in packaging format (cut tape versus bulk). This distinction affects procurement and handling but does not impact functional performance or circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the MF1/4DC9091F and MF1/4DCT52R9091F are active production components manufactured by KOA Speer Electronics, Inc., with full ROHS3 compliance and AEC-Q200 automotive qualification. Selection between these parts should be based on procurement requirements and assembly processes. The bulk-packaged MF1/4DC9091F is suitable for high-volume manual assembly or reel-fed automated processes. The cut-tape packaged MF1/4DCT52R9091F accommodates tape-and-reel handling systems and pick-and-place automation. Both parts satisfy identical electrical performance requirements and environmental operating conditions for automotive circuit applications.

Frequently Asked Questions (FAQ)

Q: Can MF1/4DCT52R9091F be used as a direct replacement for MF1/4DC9091F? A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (cut tape versus bulk). Circuit performance and reliability are equivalent.

Q: What determines whether these parts are substitutable? A: Substitutability is based on matching resistance value (9.09 kOhms), tolerance (±1%), power rating (0.25W), composition (metal film), package type (axial), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and AEC-Q200 qualification. All these parameters are identical between the two parts.

Q: Does packaging format affect circuit performance? A: No. Packaging format (bulk or cut tape) affects only procurement, storage, and assembly handling. Electrical characteristics and reliability remain unchanged.

Q: Are both parts suitable for automotive applications? A: Yes. Both parts carry AEC-Q200 qualification and are rated for the automotive operating temperature range of -55°C to 155°C.

Q: What is the difference between bulk and cut tape packaging? A: Bulk packaging is loose component format suitable for manual assembly. Cut tape packaging places components on adhesive tape in carrier strips, optimized for automated pick-and-place assembly systems.
