Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TAJS156M006RNJ is determined by the following criteria:

Primary Substitution Parameters:

• Capacitance value: 15 µF (exact match required)
• Voltage rating: 6.3 V (exact match required)
• Package / Case: 1206 (3216 Metric) (exact match required)
• Type: Molded Tantalum (exact match required)
• Operating temperature range: -55°C ~ 125°C (exact match required)
• Mounting type: Surface Mount (exact match required)

Allowable Variation Parameters:

• Tolerance: ±20% (main part) to ±10% (substitute) — tighter tolerance is acceptable
• ESR: 4 Ohm (main part) to 4.6 Ohm (substitute) — lower ESR is acceptable
• Packaging format: Bulk to Tape & Reel (TR) — format change does not affect electrical performance
• Manufacturer size code: S to A — reflects physical height variation within package specification

Identified Substitutes:

1. TAJS156K006RNJ — Upgrade substitute with tighter tolerance (±10% vs ±20%), identical ESR (4 Ohm), same package and electrical ratings
2. TAJA156M006RNJ — Manufacturer-recommended substitute with identical tolerance (±20%), improved ESR (4.6 Ohm vs 4 Ohm), same package and electrical ratings

Parameter Comparison

Engineering Selection Recommendations

TAJS156K006RNJ Selection Criteria: Select this upgrade substitute when design specifications permit tighter capacitance tolerance (±10%). This part maintains identical ESR performance and package dimensions, offering improved capacitance accuracy without electrical or mechanical compromise. Both parts are Active status with ROHS3 compliance and MSL 1 rating.

TAJA156M006RNJ Selection Criteria: Select this manufacturer-recommended substitute when lower ESR performance is beneficial (4.6 Ohm vs 4 Ohm). This part maintains identical capacitance tolerance (±20%) and voltage rating. Note the increased seated height (0.071" vs 0.047"), which requires verification against PCB layout constraints and clearance requirements. Both parts are Active status with ROHS3 compliance and MSL 1 rating.

Packaging Consideration: The main part is supplied in bulk packaging, while both substitutes are supplied in Tape & Reel (TR) format. This format change does not affect electrical performance or component functionality.

Frequently Asked Questions (FAQ)

Q: Can TAJS156K006RNJ replace TAJS156M006RNJ in all applications? A: Yes, provided the design does not require the ±20% tolerance specification. The ±10% tolerance of TAJS156K006RNJ is tighter and therefore acceptable as a direct replacement. All other electrical and mechanical parameters are identical.

Q: What is the primary difference between TAJS156K006RNJ and TAJA156M006RNJ? A: TAJS156K006RNJ offers tighter tolerance (±10% vs ±20%) with identical ESR. TAJA156M006RNJ maintains the same tolerance as the main part but provides lower ESR (4.6 Ohm vs 4 Ohm) and increased seated height (0.071" vs 0.047").

Q: Does the height difference between TAJS156M006RNJ and TAJA156M006RNJ affect PCB assembly? A: The TAJA156M006RNJ has a maximum seated height of 0.071" compared to 0.047" for TAJS156M006RNJ. Verify clearance against adjacent components, solder mask openings, and conformal coating requirements before substitution.

Q: Are all three parts ROHS3 compliant? A: Yes. TAJS156M006RNJ, TAJS156K006RNJ, and TAJA156M006RNJ are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What does ESR difference mean for circuit performance? A: Lower ESR (4.6 Ohm in TAJA156M006RNJ vs 4 Ohm in TAJS156M006RNJ) reduces impedance and heat generation in high-frequency or high-ripple-current applications. Select based on circuit requirements.

Q: Can I use Tape & Reel packaged parts in place of bulk packaged parts? A: Yes. Tape & Reel format is suitable for automated assembly processes. The electrical and mechanical specifications remain unchanged; only the packaging format differs.
