Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TS1608-472M are qualified based on the following critical parameters that must match or remain within acceptable tolerances:

Mandatory Matching Parameters:

• Inductance: 4.7 mH
• Inductance Tolerance: ±20%
• Current Rating: 60 mA
• Shielding: Shielded
• Mounting Type: Surface Mount
• Physical Dimensions: 0.260" L x 0.175" W (6.60mm x 4.45mm)
• Height - Seated (Max): 0.115" (2.92mm)
• Frequency - Self Resonant: 1 MHz
• Inductance Frequency - Test: 100 kHz
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• DC Resistance (DCR): Substitutes may have DCR values different from 13.9 Ohm maximum, provided the substitute meets the application's electrical requirements
• Operating Temperature Range: Substitutes may have extended or different temperature ranges
• Product Status: Active status substitutes are preferred for obsolete parts
• Compliance Certifications: RoHS and REACH status may vary

Two substitute parts meet these criteria: UP0.4SC-472-R (Eaton - Electronics Division) and SDS680R-475M (API Delevan Inc.).

Parameter Comparison

Engineering Selection Recommendations

UP0.4SC-472-R (Eaton - Electronics Division) is the primary substitute for TS1608-472M. This part maintains identical DC resistance (13.9 Ohm maximum) and quality factor (50 @ 100kHz), ensuring electrical performance equivalence. The extended operating temperature range (-40°C ~ 125°C) provides broader thermal coverage compared to the original part. UP0.4SC-472-R holds active product status and RoHS compliance certification, supporting long-term procurement availability and regulatory requirements.

SDS680R-475M (API Delevan Inc.) is a secondary substitute option. While this part matches all critical inductance, current rating, and physical parameters, the DC resistance specification is 25 Ohm maximum, which is higher than the original 13.9 Ohm maximum. This substitute is suitable only for applications where the increased DC resistance does not compromise circuit performance or thermal management. SDS680R-475M is active product status and ROHS3 compliant with REACH unaffected status.

Both substitutes are available in Tape & Reel packaging and maintain MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard surface mount assembly processes.

Frequently Asked Questions (FAQ)

Q: Can UP0.4SC-472-R directly replace TS1608-472M without circuit modification?

A: UP0.4SC-472-R is a direct electrical and mechanical equivalent. Both parts share identical inductance (4.7 mH), current rating (60 mA), DC resistance (13.9 Ohm maximum), and physical dimensions (0.260" L x 0.175" W, 0.115" height maximum). No circuit modification is required for substitution.

Q: What is the difference between UP0.4SC-472-R and SDS680R-475M?

A: The primary difference is DC resistance. UP0.4SC-472-R specifies 13.9 Ohm maximum DCR, matching the original TS1608-472M. SDS680R-475M specifies 25 Ohm maximum DCR. Both parts maintain identical inductance, current rating, and physical dimensions. The higher DCR in SDS680R-475M results in increased power dissipation and heat generation at rated current levels.

Q: Are both substitutes available in the same packaging format?

A: Both UP0.4SC-472-R and SDS680R-475M are supplied in Tape & Reel (TR) packaging, which is standard for surface mount assembly operations. The original TS1608-472M packaging information was not specified in available data.

Q: What is the operating temperature range difference between substitutes?

A: TS1608-472M operates from -25°C to 85°C. UP0.4SC-472-R extends this range to -40°C to 125°C, providing 15°C lower minimum and 40°C higher maximum operating temperature. SDS680R-475M operates from -40°C to 85°C, matching the original maximum but extending the minimum to -40°C. Select based on application thermal requirements.

Q: Do both substitutes meet RoHS compliance requirements?

A: UP0.4SC-472-R is RoHS compliant. SDS680R-475M is ROHS3 compliant. Both meet current RoHS standards. SDS680R-475M additionally carries REACH unaffected status.

Q: What is the quality factor (Q) specification for SDS680R-475M?

A: The Q @ Freq specification for SDS680R-475M is not provided in available technical data. UP0.4SC-472-R specifies Q of 50 @ 100kHz, matching the original TS1608-472M specification.
