Key Parameters

Substitute Part Grouping Explanation

Substitution of the SH4R7M160ST is determined by the following critical parameters:

Primary Substitution Criteria:

• Capacitance value: 4.7 µF (fixed requirement)
• Tolerance: ±20% (fixed requirement)
• Voltage rating: Equal to or greater than 160 V
• Package type: Radial, can configuration
• Mounting type: Through hole
• Lead spacing: 0.138" (3.50mm)
• Polarization: Polar

Secondary Compatibility Factors:

• ESR characteristics at 120 Hz
• Ripple current handling at operating frequencies
• Operating temperature range
• Lifetime rating at rated temperature
• RoHS3 compliance

Substitute parts are grouped into two categories: Upgrade parts (higher voltage ratings or improved specifications) and Similar parts (equivalent voltage with alternative characteristics).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Voltage Rating):

UPW2C4R7MPD (Nichicon) provides electrical equivalence at the 160 V rating with identical lead spacing and similar physical dimensions. This part offers extended lifetime (3000 Hrs @ 105°C versus 2000 Hrs) and expanded operating temperature range (-40°C to 105°C). However, UPW2C4R7MPD is also classified as obsolete, limiting its long-term availability.

Upgrade Substitutes (Higher Voltage Rating):

SEK4R7M200ST (Cornell Dubilier) operates at 200 V with equivalent ESR characteristics (42.35 Ohm @ 120Hz) and maintains the same 2000 Hrs @ 105°C lifetime. This part is currently active in production and offers expanded operating temperature range (-40°C to 105°C). The 200 V rating provides voltage margin above the original 160 V specification.

250LEX4.7MEFC8X9 (Rubycon) operates at 250 V with extended lifetime (4000 Hrs @ 125°C) and wider operating temperature range (-40°C to 125°C). This part is classified as "Not For New Designs," indicating limited future availability despite current inventory levels.

475CKE250M (Cornell Dubilier / Illinois Capacitor) operates at 250 V with active production status. Physical height is 0.531" (13.50mm), exceeding the original 0.453" dimension. This part is suitable for applications where PCB clearance permits the increased height.

Compliance Status:

All substitute parts maintain ROHS3 compliance, ensuring regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can SEK4R7M200ST directly replace SH4R7M160ST in all applications?

A: SEK4R7M200ST is electrically compatible as a direct substitute. The 200 V rating exceeds the original 160 V specification, providing voltage margin. Physical dimensions are compatible with identical lead spacing (0.138" / 3.50mm) and similar height (0.433" versus 0.453"). SEK4R7M200ST is currently in active production, addressing the obsolescence of the original part.

Q: What is the difference between upgrade and similar substitute categories?

A: Upgrade substitutes (SEK4R7M200ST, 250LEX4.7MEFC8X9, 475CKE250M) operate at voltage ratings higher than 160 V, providing design margin and extended performance characteristics. Similar substitutes (UPW2C4R7MPD) maintain the original 160 V rating with equivalent electrical performance. Selection depends on circuit voltage requirements and design constraints.

Q: Does the height difference between 475CKE250M (0.531") and the original part (0.453") affect compatibility?

A: The 0.078" (2.00mm) height increase must be evaluated against PCB layout constraints and available vertical clearance. Lead spacing remains identical at 0.138" (3.50mm), ensuring footprint compatibility. Physical height verification is required before selection.

Q: Why are some substitute parts classified as obsolete or "Not For New Designs"?

A: UPW2C4R7MPD is obsolete, indicating discontinued production. 250LEX4.7MEFC8X9 is classified as "Not For New Designs," signaling manufacturer intent to discontinue. For new designs, SEK4R7M200ST or 475CKE250M are recommended due to active production status.

Q: Are all substitute parts RoHS3 compliant?

A: All listed substitute parts maintain ROHS3 compliance, matching the regulatory status of the original SH4R7M160ST.

Q: What ESR characteristics should be considered when selecting a substitute?

A: The original SH4R7M160ST specifies 42.33 Ohm @ 120Hz. SEK4R7M200ST provides equivalent ESR at 42.35 Ohm @ 120Hz. 475CKE250M specifies 52.911 Ohm @ 120Hz, representing a 25% increase in series resistance. Circuit applications sensitive to ESR (such as high-frequency ripple filtering) should prioritize parts with matching ESR specifications.

Q: How do ripple current ratings affect substitute selection?

A: The original part handles 43 mA @ 120 Hz and 68.8 mA @ 10 kHz. SEK4R7M200ST provides 50 mA @ 120 Hz and 80 mA @ 10 kHz, offering increased ripple current capacity. 250LEX4.7MEFC8X9 and 475CKE250M provide higher ripple current ratings at elevated frequencies. Applications requiring specific ripple current handling should compare these values against circuit requirements.
