Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLE2425MDRG4 is determined by the following critical parameters:

• Reference Type: Ground Reference (Virtual)
• Output Type: Fixed
• Voltage - Output: 2.5V
• Current - Output: 20 mA
• Tolerance: ±0.8%
• Temperature Coefficient: 20ppm/°C Typical
• Noise - 10Hz to 10kHz: 100µVrms
• Voltage - Input: 4V ~ 40V
• Operating Temperature: -55°C ~ 125°C (TA)
• Package / Case: 8-SOIC (0.154", 3.90mm Width)

The TLE2425MDR meets all electrical and mechanical specifications required for direct substitution. Both parts share identical functional parameters, output characteristics, and package form factor. The primary distinction lies in product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The TLE2425MDR provides electrical and mechanical equivalence to the TLE2425MDRG4 across all specified functional parameters. However, compliance considerations must be evaluated:

The TLE2425MDRG4 maintains ROHS3 compliance, suitable for applications subject to RoHS regulations. The TLE2425MDR is RoHS non-compliant, restricting its use to applications where RoHS compliance is not required or where legacy component qualification is permitted.

Product status indicates the TLE2425MDRG4 is in Last Time Buy phase, while the TLE2425MDR is classified as Obsolete. Inventory availability differs significantly: 1042 units of TLE2425MDRG4 versus 3652 units of TLE2425MDR are currently in stock.

Selection should prioritize regulatory requirements and supply chain constraints specific to the application and target market.

Frequently Asked Questions (FAQ)

Q: Can the TLE2425MDR directly replace the TLE2425MDRG4 in existing designs?

A: Electrical and mechanical compatibility is confirmed. All output voltage, current, tolerance, temperature coefficient, and noise specifications are identical. The 8-SOIC package form factor is unchanged. Compliance requirements must be evaluated independently.

Q: What is the primary difference between these two parts?
