Substitute Part Grouping Explanation

Substitution eligibility for the TLC14IDG4 is determined by strict equivalence across the following critical parameters:

• Filter Type: Butterworth, Low Pass Switched Capacitor
• Filter Order: 4th
• Frequency - Cutoff or Center: 30kHz
• Number of Filters: 1
• Voltage - Supply: 5V ~ 12V
• Mounting Type: Surface Mount
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Base Product Number: TLC14

The TLC14ID meets all substitution criteria and is classified as a manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

The TLC14ID is the direct substitute for the discontinued TLC14IDG4. Both components share identical electrical specifications, mechanical packaging, and compliance certifications. The TLC14ID maintains active product status with current inventory availability, making it the appropriate selection for new procurement and design continuity. Both parts are ROHS3 compliant and REACH unaffected, satisfying regulatory requirements for equivalent applications.

Frequently Asked Questions (FAQ)

Q: Can the TLC14ID be used as a direct replacement for the TLC14IDG4?

A: Yes. The TLC14ID is electrically and mechanically equivalent to the TLC14IDG4 across all critical parameters: filter type, order, cutoff frequency, supply voltage range, and 8-SOIC package configuration.

Q: What is the difference between TLC14IDG4 and TLC14ID?

A: The primary difference is product status. The TLC14IDG4 is discontinued, while the TLC14ID is active with current inventory. The packaging designation differs (G4 versus standard), but electrical and functional specifications are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity ratings (MSL 1 - Unlimited).

Q: What supply voltage range does this filter support?

A: Both the TLC14IDG4 and TLC14ID operate across a 5V to 12V supply voltage range.

Q: Is the 8-SOIC package the same for both parts?

A: Yes. Both components use the 8-SOIC package with 0.154" width (3.90mm), ensuring identical PCB footprint and mounting requirements.
