Key Parameters

Substitute Part Grouping Explanation

Substitution for the MLF14FTC1K30 is determined by strict adherence to the following electrical and mechanical parameters:

• Resistance value: 1.3 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package type: MELF 0204 (exact match required)
• Composition: Thin Film (exact match required)
• Temperature Coefficient: ±50ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (minimum requirement)
• RoHS3 Compliance: Required
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part MMA02040C1301FB300 meets all these criteria. The power rating may exceed the original specification (0.4W vs. 0.25W), which is permissible as higher power ratings provide additional design margin without affecting electrical performance in circuits designed for the original component.

Parameter Comparison

Engineering Selection Recommendations

Both the MLF14FTC1K30 and MMA02040C1301FB300 are active production components with ROHS3 compliance and REACH unaffected status. The Vishay MMA02040C1301FB300 substitute includes additional automotive AEC-Q200 qualification and anti-sulfur features, providing enhanced reliability for demanding applications. The increased power rating (0.4W vs. 0.25W) does not compromise circuit performance and offers improved thermal margin. Selection between these components should be based on application requirements for automotive qualification and environmental resistance specifications.

Frequently Asked Questions (FAQ)

Q: Can MMA02040C1301FB300 be used as a direct replacement for MLF14FTC1K30?

A: Yes. Both components share identical resistance (1.3 kOhms), tolerance (±1%), package (MELF 0204), composition (thin film), temperature coefficient (±50ppm/°C), and operating temperature range (-55°C ~ 155°C). The higher power rating of the substitute (0.4W vs. 0.25W) is compatible with circuits designed for the original component.

Q: What is the significance of the higher power rating in the substitute part?

A: The MMA02040C1301FB300 is rated for 0.4W compared to the MLF14FTC1K30 at 0.25W. This higher rating provides additional thermal capacity and design margin without affecting electrical performance. The component will operate safely in applications designed for the lower-rated original part.

Q: Are there any dimensional differences between these parts?

A: Both components use the MELF 0204 package. The MLF14FTC1K30 has a length of 0.138" (4.60mm), while the MMA02040C1301FB300 has a length of 0.142" (3.60mm). This 0.004" (0.10mm) difference is within standard MELF 0204 package tolerances and does not affect PCB layout compatibility.

Q: What does AEC-Q200 qualification mean for the substitute part?

A: AEC-Q200 is an automotive electronics qualification standard. The MMA02040C1301FB300 meets this specification, indicating suitability for automotive applications with enhanced reliability requirements. This qualification is not required for the original MLF14FTC1K30 but is available in the substitute if needed.

Q: Are both parts RoHS compliant?

A: Yes. Both MLF14FTC1K30 and MMA02040C1301FB300 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
