TAJS475M010RNJ Equivalent & Substitute Parts

Part Overview

The TAJS475M010RNJ is a 4.7 µF molded tantalum capacitor manufactured by KYOCERA AVX, rated for 10 V operation in a 1206 (3216 Metric) surface mount package. This component is classified as Active product status and is designed for general purpose applications requiring stable capacitance performance across industrial temperature ranges. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package footprint and performance envelope.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TAJS475M010RNJ is determined by strict equivalence across the following critical parameters:

• Capacitance value: 4.7 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage rating: 10 V (exact match required)
• Type: Molded tantalum (exact match required)
• ESR: 5 Ohm (exact match required)
• Operating temperature range: -55°C to 125°C (exact match required)
• Package / Case: 1206 (3216 Metric) (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• MSL rating: 1 (Unlimited) (exact match required)

The substitute part 293D475X0010A2TE3 (Vishay Sprague) meets all electrical and environmental specifications. Physical height variation (1.80mm vs. 1.20mm seated height) remains within acceptable PCB assembly tolerances for 1206 package footprints and does not affect electrical performance or board-level compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the TAJS475M010RNJ and 293D475X0010A2TE3 are Active product status components with full ROHS3 compliance and REACH unaffected status, suitable for applications requiring regulatory compliance in industrial and commercial environments. Selection between these parts is based on availability and supply chain requirements, as electrical performance and environmental ratings are equivalent. The seated height difference of 0.6mm (1.20mm vs. 1.80mm) is within standard PCB assembly clearance specifications for 1206 package designs and does not impact circuit functionality or board layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can 293D475X0010A2TE3 be used as a direct replacement for TAJS475M010RNJ?

A: Yes. Both parts share identical electrical specifications (4.7 µF, ±20%, 10 V, 5 Ohm ESR), operating temperature range (-55°C to 125°C), package footprint (1206), and regulatory compliance (ROHS3, REACH unaffected). The 0.6mm height difference falls within standard PCB assembly tolerances.

Q: Are there any compatibility concerns with the height difference?

A: No. The 1206 package footprint accommodates both seated heights. Standard PCB design clearances for surface mount components allow for this variation without affecting assembly or electrical performance.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both components are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are both parts RoHS compliant?

A: Yes. Both TAJS475M010RNJ and 293D475X0010A2TE3 are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for industrial and commercial applications.

Q: What is the primary reason to consider a substitute part?

A: Substitute parts are selected based on supply availability and lead time requirements. When the primary part (TAJS475M010RNJ) has extended lead times or inventory constraints, the 293D475X0010A2TE3 provides equivalent electrical and mechanical performance for immediate procurement.
