Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the UP2B-470-R are qualified based on the following critical parameters:

Primary Matching Criteria:

• Inductance value: 47 µH (fixed)
• Inductance tolerance: ±20% (fixed)
• Shielding configuration: Unshielded (fixed)
• Mounting type: Surface Mount (fixed)
• Core type: Ferrite or equivalent unshielded construction (fixed)
• Inductance test frequency: 100 kHz (fixed)

Secondary Compatibility Parameters:

• Current rating: Minimum 1.6 A (substitute parts must support circuit current requirements)
• DC resistance: Maximum 168 mOhm (substitute parts must not exceed this threshold to maintain circuit performance)
• Operating temperature range: Minimum -40°C to 85°C (substitute parts must cover or exceed this range)
• RoHS3 compliance and MSL 1 rating (regulatory and handling requirements)

Substitute parts are grouped as direct equivalents when all primary parameters match and secondary parameters remain within acceptable engineering tolerances for the application.

Parameter Comparison

Engineering Selection Recommendations

ASPI-0804T-470M-T (Abracon LLC) is the closest electrical equivalent to the UP2B-470-R. Both parts share identical inductance, tolerance, and operating temperature specifications. The DC resistance differential of 1.2 mOhm is negligible for most circuit applications. Both are ferrite drum core designs with tape and reel packaging, ensuring compatibility with automated assembly processes. Abracon's part maintains full RoHS3 compliance and MSL 1 rating. Current rating is 1.6 A versus 1.7 A; this 0.1 A reduction requires verification that circuit peak current does not exceed 1.6 A.

P0751.473NLT (Pulse Electronics) provides an alternative with identical inductance and tolerance specifications. This part extends the operating temperature range to 130°C, offering thermal performance beyond the original specification. DC resistance reaches 168 mOhm maximum, representing a 29.2 mOhm increase from the UP2B-470-R. This resistance increase must be evaluated against circuit impedance requirements and power dissipation budgets. Tape and reel packaging is available. Current rating is 1.6 A. RoHS3 compliance and MSL 1 rating are maintained.

P0751.473NL (Pulse Electronics) is functionally equivalent to P0751.473NLT but supplied in bulk packaging rather than tape and reel format. Electrical specifications are identical to P0751.473NLT. Bulk packaging may require manual handling and is not suitable for high-volume automated assembly operations.

All substitute parts are Active in product status with confirmed inventory availability. Selection should prioritize ASPI-0804T-470M-T for direct replacement applications requiring minimal electrical parameter deviation. P0751.473NLT is suitable when extended temperature operation is required and the increased DC resistance is acceptable within circuit design margins.

Frequently Asked Questions (FAQ)

Q: Can ASPI-0804T-470M-T directly replace UP2B-470-R without circuit modification?

A: ASPI-0804T-470M-T is electrically compatible as a direct replacement. Both parts share 47 µH inductance, ±20% tolerance, ferrite drum core construction, and identical operating temperature range. The 0.1 A current rating reduction (1.6 A versus 1.7 A) requires confirmation that circuit peak current does not exceed 1.6 A. DC resistance difference of 1.2 mOhm is negligible for most applications.

Q: What is the significance of the DC resistance difference between UP2B-470-R (138.8 mOhm) and P0751.473NLT (168 mOhm)?

A: DC resistance affects power dissipation and circuit impedance. The 29.2 mOhm increase in P0751.473NLT results in proportionally higher resistive losses. For a 1.6 A circuit, this represents approximately 4.3 mW additional power dissipation compared to the UP2B-470-R. This difference is acceptable in most applications but must be evaluated against thermal and efficiency requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. ASPI-0804T-470M-T, P0751.473NL, and P0751.473NLT are all RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the UP2B-470-R compliance profile.

Q: What is the difference between P0751.473NL and P0751.473NLT?

A: Both parts are electrically identical with 47 µH inductance, 1.6 A current rating, and 168 mOhm maximum DC resistance. The primary difference is packaging: P0751.473NL is supplied in bulk format, while P0751.473NLT is supplied in Tape & Reel (TR) format. Tape and reel packaging is required for automated assembly operations.

Q: Can P0751.473NLT be used in applications requiring operation above 85°C?

A: Yes. P0751.473NLT extends the operating temperature range to -40°C to 130°C, providing 45°C additional high-temperature capability beyond the UP2B-470-R specification. This extended range is suitable for applications in elevated ambient or self-heating environments.

Q: What are the physical size differences between substitute parts?

A: UP2B-470-R dimensions are 0.550" L × 0.410" W × 0.236" H (13.97mm × 10.41mm × 6.00mm). ASPI-0804T-470M-T is 0.510" L × 0.370" W × 0.205" H (12.95mm × 9.40mm × 5.21mm). P0751.473NL and P0751.473NLT are 0.510" L × 0.370" W × 0.215" H (12.95mm × 9.40mm × 5.46mm). Abracon and Pulse parts are physically smaller, which may affect PCB layout and thermal management considerations.

Q: Is current saturation (Isat) a critical parameter for substitution?

A: Current saturation is provided for UP2B-470-R (1.4 A) and P0751.473NL/P0751.473NLT (1.6 A) but not specified for ASPI-0804T-470M-T. Saturation current defines the threshold at which inductance begins to degrade. For applications operating below 1.4 A, saturation is not a limiting factor. For circuits approaching or exceeding 1.4 A, saturation specifications should be confirmed with the manufacturer.
