Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TAJB156M016RBY are qualified based on the following criteria:

Electrical Equivalence: Capacitance value (15 µF), voltage rating (16 V), and ESR (2.5 Ohm) must remain constant. These parameters define the functional performance in the circuit.

Mechanical Compatibility: Package type (1411/3528 Metric), physical dimensions (0.138" L x 0.110" W, 2.10mm max height), and surface mount mounting type must be identical to ensure PCB layout compatibility without redesign.

Environmental & Compliance Alignment: Operating temperature range (-55°C ~ 125°C), RoHS3 compliance, and MSL rating (1) must be maintained.

Tolerance Variation: The TAJB156M016RBY operates at ±20% tolerance. A substitute with tighter tolerance (±10%) is electrically compatible and represents an upgrade path, as it maintains all other critical parameters while improving capacitance accuracy.

Packaging Format: Substitutes may differ in packaging format (Tape & Reel vs. Cut Tape & Digi-Reel®) without affecting component performance, as these are logistics and assembly considerations only.

Parameter Comparison

Engineering Selection Recommendations

TAJB156M016RNJ (Direct Substitute): This part maintains identical electrical and mechanical specifications to the TAJB156M016RBY, with the primary difference being packaging format (Tape & Reel vs. Bulk). Both parts carry Active product status and full ROHS3 compliance. Selection of this substitute is appropriate when Tape & Reel packaging is preferred for automated assembly processes or inventory management.

TAJB156K016RNJ (Upgrade Substitute): This part offers improved capacitance tolerance (±10% vs. ±20%), while maintaining all other critical electrical parameters, mechanical dimensions, and compliance certifications. The tighter tolerance specification makes this part suitable for applications requiring higher capacitance accuracy. All other functional and environmental characteristics remain equivalent. This part is available in Cut Tape & Digi-Reel® packaging format.

All three parts are Active products from KYOCERA AVX, ROHS3 compliant, and suitable for the full operating temperature range of -55°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Can TAJB156M016RNJ be used as a direct replacement for TAJB156M016RBY?

A: Yes. Both parts are electrically and mechanically identical, with 15 µF capacitance, 16 V rating, 2.5 Ohm ESR, and identical package dimensions (1411/3528 Metric). The difference is packaging format only (Tape & Reel vs. Bulk), which does not affect component performance.

Q: What is the advantage of TAJB156K016RNJ over TAJB156M016RBY?

A: TAJB156K016RNJ provides tighter capacitance tolerance (±10% vs. ±20%), resulting in improved accuracy of the capacitance value. All other electrical specifications, mechanical compatibility, and environmental ratings remain identical.

Q: Are all three parts physically interchangeable on the PCB?

A: Yes. All three parts share identical package type (1411/3528 Metric), physical dimensions (0.138" L x 0.110" W, 2.10mm max height), and surface mount configuration. No PCB layout modifications are required when substituting between these parts.

Q: Do packaging format differences affect circuit performance?

A: No. Packaging format (Bulk, Tape & Reel, or Cut Tape & Digi-Reel®) is a logistics and assembly consideration only. It does not impact electrical performance, reliability, or environmental compliance of the capacitor itself.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. TAJB156M016RNJ and TAJB156K016RNJ are both ROHS3 compliant, matching the compliance status of the TAJB156M016RBY.

Q: What is the MSL rating for these parts?

A: All three parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
