ECQ-V1473JM2 Equivalent & Substitute Parts Reference

Part Overview

The ECQ-V1473JM2 is a 0.047 µF film capacitor rated for 100V DC, manufactured by Panasonic Electronic Components in the ECQ-V series. This component features a polyester metallized-stacked dielectric with radial through-hole mounting and PC pin termination. The part is currently obsolete, making equivalent substitutes necessary for ongoing production, maintenance, and repair applications. Substitute parts must maintain electrical equivalence across capacitance, voltage rating, tolerance, and dielectric material while accommodating mechanical and packaging variations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECQ-V1473JM2 is determined by strict electrical and mechanical parameter matching:

Electrical Equivalence Requirements:

• Capacitance must be 0.047 µF
• Tolerance must be ±5%
• DC voltage rating must be 100V or higher
• Dielectric material must be polyester-based metallized construction

Mechanical Compatibility Requirements:

• Mounting type must be through-hole radial
• Lead spacing must be 0.197" (5.00mm)
• Termination must be PC pins
• Physical dimensions must accommodate existing PCB footprints

Acceptable Variations:

• Packaging format (bulk, cut tape, reel) does not affect electrical or mechanical compatibility
• Operating temperature range may exceed the original specification
• AC voltage rating may differ from DC rating
• Physical size variations are acceptable if lead spacing and mounting type remain constant

The substitute parts B32529C1473J000 and B32529C1473J289 meet all electrical and mechanical requirements for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

Both B32529C1473J000 and B32529C1473J289 are electrically and mechanically equivalent to the ECQ-V1473JM2 and are suitable for direct substitution in applications requiring a 0.047 µF, 100V DC film capacitor with radial through-hole mounting.

• Extended operating temperature range (-55°C ~ 125°C) provides thermal margin

B32529C1473J289 (Cut Tape Packaging):

• Active product status ensures long-term availability
• ROHS3 compliant for regulatory compliance
• AEC-Q200 rated for automotive applications
• Cut tape packaging suitable for automated assembly processes
• Extended operating temperature range (-55°C ~ 125°C) provides thermal margin
• Identical electrical and mechanical specifications to B32529C1473J000

Selection between these two substitutes depends on procurement and assembly requirements. Both parts satisfy all electrical and mechanical compatibility criteria for the ECQ-V1473JM2 application.

Frequently Asked Questions (FAQ)

Q: Can B32529C1473J000 and B32529C1473J289 be used interchangeably with ECQ-V1473JM2?

A: Yes. Both parts meet all electrical specifications (0.047 µF, ±5% tolerance, 100V DC rating) and mechanical requirements (radial through-hole, 5.00mm lead spacing, PC pins). The only difference is packaging format (bulk versus cut tape), which does not affect electrical or mechanical compatibility.

Q: What is the difference between B32529C1473J000 and B32529C1473J289?

A: Both parts are electrically and mechanically identical. The difference is packaging format: B32529C1473J000 is supplied in bulk, while B32529C1473J289 is supplied in cut tape. Selection depends on assembly process requirements and procurement volume.

Q: Will the smaller physical dimensions of the substitute parts affect PCB layout?

A: The substitute parts (7.30mm x 2.50mm) are physically smaller than the original ECQ-V1473JM2 (7.50mm x 3.20mm). However, lead spacing remains constant at 5.00mm, ensuring PCB footprint compatibility. The reduced height (6.50mm versus 8.00mm) may provide additional clearance in space-constrained applications.

Q: Are the substitute parts suitable for automotive applications?

A: Yes. Both B32529C1473J000 and B32529C1473J289 carry AEC-Q200 ratings, qualifying them for automotive use. The original ECQ-V1473JM2 does not specify automotive qualification.

Q: What is the significance of the extended operating temperature range in the substitute parts?

A: The substitute parts operate from -55°C to 125°C, compared to the original part's -40°C to 105°C range. This extended range provides additional thermal margin and may improve reliability in temperature-extreme environments, though it does not affect compatibility in applications within the original temperature specification.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both B32529C1473J000 and B32529C1473J289 are ROHS3 compliant. The original ECQ-V1473JM2 does not specify RoHS status.
