Substitute Part Grouping Explanation

Substitute parts for the BD46292G-TR are identified based on strict parametric equivalence across the following critical criteria:

Electrical Parameters (Must Match):

• Voltage threshold: 2.9V
• Number of monitored channels: 1
• Output type: Push-Pull, Totem Pole
• Reset polarity: Active Low
• Reset timeout: 180ms Minimum
• Operating temperature range: -40°C ~ 105°C

Mechanical Parameters (Must Match):

• Package type: SC-74A, SOT-753
• Device package: 5-SSOP
• Mounting type: Surface Mount
• Packaging format: Tape & Reel (TR)

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

The BD46E292G-MTR qualifies as a parametric equivalent because it maintains identical electrical specifications, mechanical compatibility, and regulatory compliance across all critical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the BD46292G-TR and BD46E292G-MTR are Active status products manufactured by Rohm Semiconductor with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on inventory availability and supply chain requirements. The BD46E292G-MTR offers higher current inventory (3831 units versus 2973 units), making it suitable for applications requiring extended lead time assurance or higher volume procurement. Both parts are functionally interchangeable in applications requiring a 2.9V single-channel voltage supervisor with push-pull output and 180ms minimum reset timeout in the -40°C to 105°C operating range.

Frequently Asked Questions (FAQ)

Q: Can BD46E292G-MTR be used as a direct replacement for BD46292G-TR?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical voltage threshold (2.9V), output configuration (push-pull, totem pole), reset characteristics (active low, 180ms minimum), operating temperature range (-40°C to 105°C), and package specifications (5-SSOP, SC-74A, SOT-753). Both are ROHS3 compliant and REACH unaffected.

Q: What are the key differences between these two parts?

A: The primary differences are the base product number designation (BD46292 versus BD46E292) and moisture sensitivity level rating (MSL 1 for BD46292G-TR versus MSL 3 for BD46E292G-MTR). Electrical performance and mechanical compatibility remain identical.

Q: Are there any package or pinout differences?

A: No. Both parts use the identical SC-74A, SOT-753 package in 5-SSOP configuration with surface mount mounting type and tape & reel packaging format.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on current inventory availability, supplier lead times, and procurement preferences. Both maintain Active product status with full regulatory compliance.

Q: Are these parts suitable for high-volume production?

A: Yes. Both parts are available in tape & reel packaging format suitable for automated assembly. Current inventory levels (2973 and 3831 units respectively) support production requirements. Confirm availability with your supplier for specific volume requirements.
