RN5VD29CA-TR-FE Equivalent & Substitute Parts

Part Overview

The RN5VD29CA-TR-FE is an active voltage detector supervisor integrated circuit manufactured by Nisshinbo Micro Devices Inc. This single-channel power management IC operates as a push-pull, totem pole output device in a surface-mount SOT-23-5 package. The device monitors a 2.9V voltage threshold and is designed for applications requiring voltage supervision and reset signal generation.

The RN5VD29CA-TR-FE maintains active product status with 3,174 units in current inventory. Equivalent substitute parts are identified based on matching electrical specifications, package compatibility, and operational parameters. Substitute identification becomes necessary for supply chain continuity, inventory optimization, or design flexibility when the primary part number becomes unavailable.

Substitute Part Grouping Explanation

Substitute parts for the RN5VD29CA-TR-FE are identified through parametric equivalence matching. The substitution logic is based on the following critical parameters that must remain constant across all equivalent devices:

Mandatory Matching Parameters:

• Voltage threshold detection: 2.9V
• Output type: Push-Pull, Totem Pole configuration
• Package format: SOT-23-5 (SC-74A, SOT-753)
• Mounting type: Surface Mount
• Number of monitored voltages: 1 channel
• Operating temperature range: -40°C to 85°C
• Packaging delivery format: Tape & Reel (TR)
• Compliance standards: RoHS Compliant, MSL 1

Parts meeting all these parameters are classified as direct parametric equivalents and may be substituted in applications where the RN5VD29CA-TR-FE is specified, provided that the application does not contain design-specific dependencies on the RN5VD series designation.

Parameter Comparison

Engineering Selection Recommendations

Both the RN5VD29CA-TR-FE and R3112N291C-TR-FE are active, production-status components manufactured by Nisshinbo Micro Devices Inc. with identical electrical and mechanical specifications. Selection between these parts may be based on the following factors:

Inventory Considerations: The RN5VD29CA-TR-FE maintains 3,174 units in stock, while the R3112N291C-TR-FE maintains 3,110 units. Both quantities support standard production volumes.

Compliance and Certification: Both parts carry identical RoHS compliance status and MSL 1 moisture sensitivity ratings, meeting equivalent environmental and regulatory requirements for industrial and commercial applications.

Series Designation: The RN5VD29CA-TR-FE belongs to the RN5VD series, while the R3112N291C-TR-FE belongs to the R3112x series. Applications with series-specific design documentation should reference the appropriate manufacturer datasheet to confirm functional equivalence beyond parametric matching.

Supply Chain Strategy: Either part may be selected as a primary or secondary source component based on supplier availability, lead time, or cost considerations, as all specified parameters are equivalent.

Frequently Asked Questions (FAQ)

Q: Can the R3112N291C-TR-FE be used as a direct replacement for the RN5VD29CA-TR-FE in existing designs?

A: Yes. Both parts are parametrically equivalent across all specified electrical and mechanical parameters, including voltage threshold (2.9V), output configuration (push-pull, totem pole), package type (SOT-23-5), operating temperature range (-40°C to 85°C), and compliance certifications. Direct substitution is supported at the component level based on provided specifications.

Q: Are there any differences in the SOT-23-5 package between these parts?

A: No. Both parts use identical package specifications: SC-74A, SOT-753 surface-mount format with Tape & Reel delivery. Pin configuration and physical dimensions are equivalent.

Q: What is the significance of the different series designations (RN5VD vs. R3112x)?

A: Series designations indicate different product lines within the Nisshinbo Micro Devices Inc. portfolio. However, the parts specified here are parametrically equivalent. Design documentation should be reviewed to determine if series-specific requirements exist beyond the electrical and mechanical parameters provided.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both the RN5VD29CA-TR-FE and R3112N291C-TR-FE carry MSL 1 (Unlimited) moisture sensitivity level, indicating equivalent handling and storage requirements.

Q: Which part should be selected for new designs?

A: Selection between these parts is based on supply chain factors, inventory availability, or design preference, as all electrical and mechanical specifications are identical. Either part is suitable for new designs requiring a 2.9V single-channel voltage detector in SOT-23-5 packaging.

Q: Are both parts RoHS compliant?

A: Yes. Both the RN5VD29CA-TR-FE and R3112N291C-TR-FE are RoHS compliant and meet equivalent environmental standards.
