Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ACML-0603U-331-T is determined by the following critical parameters:

Primary Matching Criteria:

• Impedance value of 330 Ohms at 100 MHz
• Current rating of 1.5A or greater
• DC resistance (DCR) maximum of 70mOhm
• 0603 (1608 Metric) package footprint
• Surface mount mounting type
• Operating temperature range of -55°C to 125°C or wider
• Single-line (1LN) configuration

Compliance Requirements:

• RoHS3 compliance or equivalent
• MSL rating of 1 (Unlimited)
• REACH unaffected status

Parts meeting all primary matching criteria and compliance requirements are classified as parametric equivalents. Parts with minor deviations in impedance value (within 10% tolerance) or higher current ratings are noted for application-specific evaluation based on circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

Full Parametric Equivalents:

BBUP00160805331Y00 (Pulse Electronics) and BLM18SG331TN1D (Murata Electronics) are complete parametric equivalents to the ACML-0603U-331-T. Both parts match all critical electrical specifications (330 Ohms @ 100 MHz, 1.5A current rating, 70mOhm DCR) and mechanical requirements (0603 package, surface mount). Both maintain identical compliance certifications (ROHS3, MSL 1, REACH unaffected). These parts are suitable for direct substitution in applications where the ACML-0603U-331-T is specified.

Partial Equivalent with Design Considerations:

HFZ 1608PF-301T22 (TAI-TECH Advanced Electronics) presents a partial equivalent with the following characteristics: impedance of 300 Ohms @ 100 MHz (9% lower than the 330 Ohm specification) and a higher current rating of 2.2A (compared to 1.5A). The part maintains identical DCR (70mOhm), package footprint (0603), and operating temperature range. This part is suitable for applications where the lower impedance value and higher current capacity are acceptable within circuit design margins. RoHS compliance is confirmed, though specific ROHS3 designation is not provided in the data.

All substitute parts are in active production status with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can BBUP00160805331Y00 be used as a direct replacement for ACML-0603U-331-T?

A: Yes. BBUP00160805331Y00 matches all critical electrical parameters (330 Ohms @ 100 MHz, 1.5A, 70mOhm DCR) and mechanical specifications (0603 package, surface mount). Both parts maintain identical compliance ratings (ROHS3, MSL 1, REACH unaffected) and operating temperature range (-55°C to 125°C). Direct substitution is supported.

Q: What is the difference between BLM18SG331TN1D and ACML-0603U-331-T?

A: BLM18SG331TN1D is a parametric equivalent with identical electrical specifications (330 Ohms @ 100 MHz, 1.5A, 70mOhm DCR) and package type (0603). The primary physical difference is height: BLM18SG331TN1D has a maximum height of 0.026" (0.65mm) compared to 0.037" (0.95mm) for ACML-0603U-331-T. Both parts are RoHS3 compliant with MSL 1 rating. The lower profile of the Murata part may be advantageous in space-constrained designs.

Q: Is HFZ 1608PF-301T22 suitable for my application?

A: HFZ 1608PF-301T22 has an impedance of 300 Ohms @ 100 MHz, which is 10% lower than the 330 Ohm specification of ACML-0603U-331-T. The part offers a higher current rating (2.2A versus 1.5A) and maintains the same DCR (70mOhm) and package footprint (0603). Suitability depends on whether the lower impedance value and higher current capacity are compatible with your circuit design requirements.

Q: Are all substitute parts available in the same packaging options?

A: Packaging formats differ among substitutes. ACML-0603U-331-T is available in standard packaging. BBUP00160805331Y00 is supplied in Tape & Reel (TR) format. BLM18SG331TN1D is available in Cut Tape (CT) and Digi-Reel® format. HFZ 1608PF-301T22 is supplied in Tape & Reel (TR) format. Verify packaging compatibility with your procurement and assembly processes.

Q: Do all parts meet the same compliance standards?

A: ACML-0603U-331-T, BBUP00160805331Y00, and BLM18SG331TN1D are all ROHS3 compliant with MSL 1 (Unlimited) rating and REACH unaffected status. HFZ 1608PF-301T22 is RoHS compliant with MSL 1 rating and REACH unaffected status, though specific ROHS3 designation is not provided. All parts meet the environmental and regulatory requirements for standard industrial applications.

Q: What is the impact of height differences between substitute parts?

A: ACML-0603U-331-T and HFZ 1608PF-301T22 have a maximum height of 0.037" (0.95mm), while BBUP00160805331Y00 and BLM18SG331TN1D have a maximum height of 0.026" (0.65mm). In applications with tight vertical clearance constraints, the lower-profile parts (Pulse Electronics and Murata) offer design advantages. In standard applications, height differences are not a limiting factor.
