SHR47M100ST

Part Overview

The SHR47M100ST is a 0.47 µF, 100 V aluminum electrolytic capacitor in radial configuration manufactured by Cornell Dubilier Electronics (CDE). This part is classified as obsolete and is no longer in active production. Finding suitable substitute components is necessary to maintain design continuity for applications currently using this capacitor, as inventory depletion will eventually occur.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SHR47M100ST is based on maintaining electrical and mechanical compatibility. The critical parameters governing substitution are:

• Capacitance Value: 0.47 µF (identical)
• Voltage Rating: 100 V (minimum requirement; equal or higher voltage ratings are acceptable)
• Tolerance: ±20% (matching tolerance specification)
• Package Type: Radial, Can configuration (identical mechanical form factor)
• Mounting: Through Hole (identical board attachment method)
• Lead Spacing: 0.079" (2.00mm) (critical for PCB layout compatibility)
• Physical Dimensions: 0.197" Dia (5.00mm) and height within compatible range
• Temperature Characteristics: -40°C ~ 105°C operating range and 2000 Hrs @ 105°C minimum lifetime

The substitute part 474CKH100M, manufactured by Cornell Dubilier / Illinois Capacitor, meets all these criteria and is classified as an active product, making it suitable for direct replacement in applications currently using the SHR47M100ST.

Parameter Comparison

Engineering Selection Recommendations

The 474CKH100M is the primary substitute for the obsolete SHR47M100ST. The following factors support this selection:

1. Product Status: The 474CKH100M is an active product with continuous manufacturing, whereas the SHR47M100ST is obsolete. This ensures long-term supply availability.

2. Compliance & Certifications: Both parts are ROHS3 Compliant and carry identical ECCN (EAR99) and HTSUS (8532.22.0020) classifications, confirming regulatory equivalence for export and trade purposes.

3. Electrical Compatibility: Both parts maintain identical capacitance (0.47 µF), voltage rating (100 V), tolerance (±20%), and temperature characteristics (2000 Hrs @ 105°C). The 474CKH100M provides measured ESR data (282.19Ohm @ 120Hz), which the SHR47M100ST does not specify.

4. Mechanical Compatibility: Both parts share identical lead spacing (0.079" / 2.00mm) and diameter (0.197" / 5.00mm). The 474CKH100M has a slightly taller maximum seated height (0.492" versus 0.433"), which must be verified against application-specific clearance requirements, but does not preclude substitution in most general-purpose applications.

Frequently Asked Questions (FAQ)

Q: Can the 474CKH100M be used as a direct replacement for the SHR47M100ST?

A: Yes. Both parts are 0.47 µF, 100 V aluminum electrolytic capacitors with identical electrical ratings, tolerance specifications, lead spacing, and package configuration. The 474CKH100M is recommended for all new designs and production applications.

Q: Are there any physical compatibility issues between these parts?

A: The 474CKH100M is 0.059" (1.5mm) taller than the SHR47M100ST (0.492" maximum versus 0.433" maximum seated height). Verify that the PCB layout and enclosure clearance accommodate this dimension. In most general-purpose applications, this height difference is not problematic.

Q: What is the difference between the SH and CKH series?

A: These are different internal series designations within Cornell Dubilier's product line. The CKH series (474CKH100M) is an active production line, while the SH series (SHR47M100ST) has been discontinued. Both meet the same electrical and mechanical specifications for this capacitance and voltage rating.

Q: Why does the 474CKH100M specify ESR while the SHR47M100ST does not?

A: The 474CKH100M provides measured ESR data (282.19Ohm @ 120Hz) as part of its active product documentation. The SHR47M100ST's ESR characteristics were not provided in available data. For applications sensitive to ESR, the specified value for the 474CKH100M (282.19Ohm @ 120Hz) can be used for circuit analysis and design verification.

Q: What is the difference between MSL ratings for these parts?

A: The SHR47M100ST lists MSL as "Not Applicable" while the 474CKH100M specifies MSL 1 (Unlimited). MSL primarily affects soldering and moisture exposure during assembly. For through-hole mounted components, this difference has minimal practical impact on typical circuit board assembly processes.

Q: Are both parts RoHS compliant?

A: Yes. Both the SHR47M100ST and 474CKH100M are ROHS3 Compliant, confirming compliance with Restriction of Hazardous Substances directives. Both share the same ECCN (EAR99) and HTSUS (8532.22.0020) trade classifications.
