Substitute Part Grouping Explanation

Substitution of the MF1/4DC1004F is based on electrical and mechanical parameter equivalence. The primary substitution criterion is packaging format. The main part is supplied in bulk packaging, while the identified substitute MF1/4DCT52R1004F is supplied in cut tape (CT) format. Both parts share identical electrical specifications: 1 MOhms resistance, ±1% tolerance, 0.25W power rating, metal film composition, and automotive AEC-Q200 qualification. Physical dimensions, temperature coefficient, and operating temperature range are identical across both parts. The substitution is valid when cut tape packaging is acceptable for the application or when bulk inventory is unavailable.

Parameter Comparison

Engineering Selection Recommendations

Both the MF1/4DC1004F and MF1/4DCT52R1004F are active production parts from KOA Speer Electronics, Inc., with full ROHS3 compliance and automotive AEC-Q200 qualification. Selection between these parts depends on packaging requirements and assembly process compatibility. The bulk-packaged MF1/4DC1004F is suitable for manual assembly or applications where loose component handling is standard. The cut tape format MF1/4DCT52R1004F is optimized for automated pick-and-place assembly systems and tape-fed component feeders. Both parts maintain identical electrical performance and thermal characteristics across the full -55°C to 155°C operating range.

Frequently Asked Questions (FAQ)
