Substitute Part Grouping Explanation

Substitute parts for the ACML-0402-601-T are categorized based on the following substitution criteria:

Direct Equivalents (600 Ohm @ 100 MHz): Parts matching the exact impedance specification of 600 Ohms at 100 MHz with equal or higher current ratings and identical package dimensions.

Parametric Equivalents (500 Ohm @ 100 MHz): Parts with 500 Ohm impedance at 100 MHz, representing a 16.7% reduction in impedance. These parts maintain identical package form factor, DC resistance, and operating temperature range but operate at a lower impedance level.

All substitute parts maintain the following critical parameters:

Package / Case: 0402 (1005 Metric)
DC Resistance (DCR) (Max): 1 Ohm
Operating Temperature: -55°C ~ 125 °C
Mounting Type: Surface Mount

Engineering Selection Recommendations

Direct Impedance Match (600 Ohms @ 100 MHz):

The 74279279 (Würth Elektronik WE-CBF series) and ILBB0402ER601V (Vishay Dale ILBB-0402 series) provide direct electrical equivalence to the ACML-0402-601-T with identical impedance specifications. Both parts exceed the original current rating at 200mA, providing additional design margin. All three 600 Ohm variants maintain ROHS3 compliance, MSL Level 1, and identical operating temperature ranges. The 74279279 offers the lowest profile at 0.022" height, while ILBB0402ER601V maintains 0.024" height. Both are available in Tape & Reel packaging suitable for automated assembly.

Parametric Equivalents (500 Ohms @ 100 MHz):

The BMC1EY0500AN (TE Connectivity BMC series) and FB100505T-501Y-S (Cal-Chip Electronics FB series) operate at 500 Ohms impedance, representing a 16.7% reduction from the original specification. These parts maintain identical DC resistance, current rating, and operating temperature parameters. Selection of 500 Ohm variants requires circuit-level validation to confirm acceptable performance at the reduced impedance level. The FB100505T-501Y-S provides higher inventory availability at 101,027 pieces. BMC1EY0500AN is supplied in Cut Tape packaging, while FB100505T-501Y-S is available in Tape & Reel format.

All substitute parts maintain Active product status and full environmental compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the 74279279 or ILBB0402ER601V be used as direct replacements for the ACML-0402-601-T?

A: Yes. Both parts match the 600 Ohms @ 100 MHz impedance specification, maintain identical DC resistance and operating temperature ranges, and are packaged in the same 0402 (1005 Metric) form factor. Both exceed the original 100mA current rating at 200mA, providing additional design margin. All three parts are ROHS3 compliant with MSL Level 1 ratings.

Q: What is the difference between the 600 Ohm and 500 Ohm substitute options?

A: The 600 Ohm variants (74279279 and ILBB0402ER601V) provide direct electrical equivalence to the ACML-0402-601-T. The 500 Ohm variants (BMC1EY0500AN and FB100505T-501Y-S) operate at 16.7% lower impedance. Selection of 500 Ohm parts requires circuit validation to confirm acceptable EMI suppression performance at the reduced impedance level.

Q: Are there packaging differences between substitute parts?

A: Yes. The ACML-0402-601-T, 74279279, ILBB0402ER601V, and FB100505T-501Y-S are supplied in Tape & Reel (TR) packaging suitable for automated assembly. The BMC1EY0500AN is supplied in Cut Tape (CT) packaging, which may require manual handling or alternative feeder compatibility depending on assembly equipment.

Q: Do all substitute parts meet the same environmental compliance standards?

A: Yes. All substitute parts listed are ROHS3 compliant, REACH unaffected, and rated for -55°C to 125°C operating temperature. All parts maintain MSL Level 1 (Unlimited) moisture sensitivity ratings.

Q: What is the height difference between the ACML-0402-601-T and substitute parts?

A: The ACML-0402-601-T has a maximum height of 0.026" (0.65mm). The 74279279 is the lowest at 0.022" (0.55mm). The ILBB0402ER601V, BMC1EY0500AN, and FB100505T-501Y-S are all 0.024" (0.60mm). These minor height variations may be relevant for applications with strict PCB clearance constraints.
