BA82903YF-CE2 Equivalent & Substitute Parts

Part Overview

The BA82903YF-CE2 is a general-purpose dual comparator integrated circuit manufactured by Rohm Semiconductor. This device features open-collector output configuration and operates across a wide supply voltage range of 2V to 36V (single supply) or ±1V to ±18V (dual supply). The component is housed in an 8-SOIC surface-mount package and is classified as Active product status, indicating continued availability and suitability for new designs.

Substitute parts become necessary when the primary part number experiences supply constraints, inventory depletion, or when design requirements mandate alternative packaging or compliance certifications. The BA82903YF-CE2 has documented equivalent alternatives that maintain electrical and mechanical compatibility while offering different availability profiles or compliance attributes.

Engineering Selection Recommendations

Primary Selection: BA82903YF-CE2

The BA82903YF-CE2 is the recommended choice for new designs. This part carries Active product status, confirming ongoing manufacturer support and availability. The device is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. Current inventory of 3900 pieces supports production requirements. The MSL rating of 3 (168 hours) is standard for this device category and requires standard moisture control during storage and handling.

Substitute Selection: BA2903WF-E2

The BA2903WF-E2 serves as a parametric equivalent for applications where the primary part is unavailable. All electrical specifications and package dimensions are identical to the BA82903YF-CE2. However, this part carries a "Not For New Designs" product status designation, indicating that Rohm Semiconductor does not recommend its use in new development projects. The MSL rating of 1 (Unlimited) provides superior moisture tolerance compared to the primary part.

Selection Criteria:

For new product development, select BA82903YF-CE2. For legacy system maintenance, field repairs, or situations where BA82903YF-CE2 inventory is exhausted, BA2903WF-E2 provides electrical and mechanical compatibility. Both parts are manufactured by Rohm Semiconductor and share identical functional performance within the specified parameter range.

Frequently Asked Questions (FAQ)

Q: Can BA2903WF-E2 be used as a direct replacement for BA82903YF-CE2 in new designs?

A: BA2903WF-E2 meets all electrical and mechanical specifications for functional equivalency. However, Rohm Semiconductor designates BA2903WF-E2 as "Not For New Designs." For new product development, BA82903YF-CE2 is the appropriate selection due to its Active product status.

Q: What is the difference in Moisture Sensitivity Level (MSL) between these parts?

A: BA82903YF-CE2 has MSL 3 (168 hours), while BA2903WF-E2 has MSL 1 (Unlimited). MSL 1 indicates the part can be stored indefinitely without moisture absorption concerns. MSL 3 requires moisture control and limits storage time to 168 hours after package opening. Both ratings are within acceptable ranges for standard manufacturing environments.

Q: Are the package dimensions identical between BA82903YF-CE2 and BA2903WF-E2?

A: Yes. Both parts use 8-SOIC surface-mount packaging with identical dimensions of 0.173" width and 4.40mm width. PCB footprints and reflow profiles are interchangeable.

Q: Do both parts meet current regulatory compliance standards?

A: Yes. Both BA82903YF-CE2 and BA2903WF-E2 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What is the supply voltage operating range for these comparators?

A: Both parts operate with single supply voltage from 2V to 36V or dual supply voltage from ±1V to ±18V, providing flexibility for various circuit configurations.

Q: Are there any differences in electrical performance between these parts?

A: No. Both parts share identical electrical specifications including input offset voltage (5mV @ 5V), input bias current (0.25µA @ 5V), output current (16mA @ 5V), quiescent current (1mA maximum), and propagation delay (400ns typical).
