Substitute Part Grouping Explanation

Substitute parts for the EMK107ABJ475MA-T are classified into two categories based on electrical and mechanical compatibility:

Category 1: Parametric Equivalents (Identical Electrical Specifications)

Parts in this category maintain identical capacitance (4.7 µF), voltage rating (16V), tolerance (±20%), temperature coefficient (X5R), and operating temperature range (-55°C ~ 85°C). These parts are direct functional replacements from different manufacturers or alternative series within the same manufacturer. Parametric equivalents include:

MSASE168AB5475MTNA01 (Taiyo Yuden MSAS Series)
0603X475M160CT (Walsin Technology Corporation)
GRM188R61C475MAAJD (Murata Electronics GRM Series)
GRM188R61C475ME11D (Murata Electronics GRM Series)
KGM15BR51C475MT (KYOCERA AVX KGM Series)

Category 2: Similar Substitutes (Modified Temperature Coefficient)

Parts in this category maintain identical capacitance (4.7 µF), voltage rating (16V), and package (0603), but feature an X6S temperature coefficient instead of X5R. The X6S coefficient provides an extended operating temperature range (-55°C ~ 105°C) and tighter tolerance (±10% instead of ±20%). These parts are suitable for applications requiring enhanced temperature stability:

EMK107BC6475KA-T (Taiyo Yuden, Cut Tape packaging)
EMK107BC6475MA-T (Taiyo Yuden, Tape & Reel packaging)

All substitute parts comply with ROHS3, maintain MSL 1 (Unlimited) moisture sensitivity, and are REACH Unaffected.

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications)

When the EMK107ABJ475MA-T is unavailable and the design requires exact electrical and thermal characteristics, select from the parametric equivalent parts with Active product status:

GRM188R61C475ME11D (Murata Electronics): Highest inventory availability (14,092 pcs) with Active status and Tape & Reel packaging. Identical X5R temperature coefficient and operating range.
MSASE168AB5475MTNA01 (Taiyo Yuden MSAS Series): Active status alternative from the original manufacturer with 4,525 pcs in stock. Maintains identical specifications with Cut Tape & Digi-Reel® packaging option.
KGM15BR51C475MT (KYOCERA AVX): Active status part with identical electrical specifications and Tape & Reel packaging.
0603X475M160CT (Walsin Technology Corporation): Active status alternative with identical specifications, though lower inventory (910 pcs).

For Enhanced Temperature Performance

When the design can accommodate extended operating temperature range (-55°C ~ 105°C) and tighter tolerance (±10%), the X6S temperature coefficient alternatives provide improved capacitance stability:

EMK107BC6475MA-T (Taiyo Yuden): Tape & Reel packaging with X6S coefficient and ±10% tolerance. Maintains same manufacturer lineage as the primary part.

Compliance Considerations

All substitute parts maintain ROHS3 compliance, MSL 1 (Unlimited) moisture sensitivity, and REACH Unaffected status, ensuring regulatory alignment with the original part.

Frequently Asked Questions (FAQ)

Q: Can I use GRM188R61C475ME11D as a direct replacement for EMK107ABJ475MA-T?

A: Yes. Both parts share identical electrical specifications: 4.7 µF capacitance, 16V voltage rating, ±20% tolerance, X5R temperature coefficient, and -55°C ~ 85°C operating range. Both are 0603 (1608 Metric) surface mount MLCCs with 0.037" maximum thickness. The primary difference is manufacturer (Murata vs. Taiyo Yuden). GRM188R61C475ME11D has Active product status and higher inventory availability.

Q: What is the difference between X5R and X6S temperature coefficients?

A: X5R and X6S are temperature coefficient classifications that define capacitance stability across operating temperature ranges. X5R maintains capacitance within ±15% across -55°C ~ 85°C. X6S maintains capacitance within ±15% across -55°C ~ 105°C, providing extended high-temperature operation. The X6S alternatives (EMK107BC6475KA-T and EMK107BC6475MA-T) also feature ±10% tolerance instead of ±20%, offering tighter capacitance control.

Q: Are there packaging differences between substitute parts?

A: Yes. The main part (EMK107ABJ475MA-T) uses Tape & Reel (TR) packaging. Parametric equivalents offer multiple packaging options: MSASE168AB5475MTNA01 uses Cut Tape (CT) & Digi-Reel®, while GRM188R61C475ME11D and KGM15BR51C475MT use Tape & Reel (TR). EMK107BC6475KA-T uses Cut Tape (CT) & Digi-Reel®, while EMK107BC6475MA-T uses Tape & Reel (TR). Packaging selection depends on assembly equipment compatibility and procurement requirements.

Q: Why is EMK107ABJ475MA-T marked "Not For New Designs"?

A: This status indicates the part has been superseded by the manufacturer and is no longer recommended for new product development. However, it remains available for existing design support and legacy system maintenance. The parametric equivalents with Active status (GRM188R61C475ME11D, MSASE168AB5475MTNA01, KGM15BR51C475MT, 0603X475M160CT) are the recommended alternatives for new designs.

Q: Can I substitute EMK107BC6475MA-T (X6S) for EMK107ABJ475MA-T (X5R) in my existing design?

A: Substitution is possible if the design can accommodate the extended operating temperature range (-55°C ~ 105°C vs. -55°C ~ 85°C) and the slightly increased thickness (0.039" vs. 0.037"). The X6S coefficient provides superior temperature stability. However, verify PCB layout clearances and thermal requirements before implementation. Both parts maintain identical 4.7 µF capacitance and 16V voltage rating.

Q: Which substitute part has the best inventory availability?

A: GRM188R61C475ME11D (Murata Electronics) has the highest inventory with 14,092 pcs in stock. This part is a parametric equivalent with Active product status, Tape & Reel packaging, and identical electrical specifications to the main part.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment with the original EMK107ABJ475MA-T.
