Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DA1206D301R-00 is determined by the following critical parameters:

Primary Matching Criteria:

• Package / Case: 1206 (3216 Metric), Array, 8 PC Pad
• Mounting Type: Surface Mount
• Number of Lines: 4
• Physical Dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm)

Electrical Compatibility Criteria:

• Impedance @ 100 MHz: 300 Ohms (direct match) or 220 Ohms (reduced impedance alternative)
• Current Rating (Max): Equal to or greater than 400mA (direct match) or reduced rating for signal-line applications
• DC Resistance (Max): 400mOhm or lower
• Operating Temperature Range: -40°C ~ 125°C or extended range

Substitutes are classified into two categories: direct equivalents maintaining identical electrical specifications, and similar alternatives with modified impedance or current ratings suitable for specific application contexts.

Engineering Selection Recommendations

DA1206D301R-10 (Direct Equivalent - Recommended Primary Substitute)

The DA1206D301R-10 is the direct functional equivalent of the DA1206D301R-00. Both parts maintain identical electrical specifications: 300 Ohms impedance at 100 MHz, 400mA maximum current rating, and 400mOhm DC resistance. The DA1206D301R-10 is manufactured by the same supplier (Laird-Signal Integrity Products) and shares the same package configuration and operating temperature range. The primary distinction is product status: DA1206D301R-10 is active with 17,100 pieces in stock, whereas DA1206D301R-00 is obsolete. The DA1206D301R-10 is supplied in Tape & Reel packaging and is ROHS3 compliant, addressing regulatory requirements for new production.

BLA31BD221SN4D (Similar Alternative - Conditional Substitution)

The BLA31BD221SN4D (Murata Electronics EMIFIL® BLA31 series) is a similar ferrite bead array with modified electrical specifications. This part maintains the same 1206 package footprint and 4-line configuration but operates at 220 Ohms impedance at 100 MHz with a reduced maximum current rating of 150mA and lower DC resistance of 350mOhm. The BLA31BD221SN4D is designated for signal-line applications and is ROHS3 compliant. This substitute is suitable only for applications where the reduced impedance and current rating are compatible with circuit requirements. The extended operating temperature range (-55°C ~ 125°C) provides additional thermal margin.

Frequently Asked Questions (FAQ)

Q: Can DA1206D301R-10 be used as a direct replacement for DA1206D301R-00?

A: Yes. Both parts share identical electrical specifications (300 Ohms @ 100 MHz, 400mA current rating, 400mOhm DC resistance), the same 1206 package footprint, and equivalent operating temperature range (-40°C ~ 125°C). The primary difference is product status and compliance certification. DA1206D301R-10 is active and ROHS3 compliant.

Q: What are the limitations of using BLA31BD221SN4D as a substitute?

A: The BLA31BD221SN4D has reduced electrical specifications compared to the main part. The impedance is 220 Ohms instead of 300 Ohms, and the maximum current rating is 150mA instead of 400mA. This substitute is suitable only for signal-line applications where these reduced ratings are acceptable. Verify circuit requirements before substitution.

Q: Are there physical compatibility concerns when substituting these parts?

A: All three parts share the same 1206 (3216 Metric) package footprint and 8-pad array configuration. However, height specifications differ slightly: DA1206D301R-00 is 0.032" (0.80mm), DA1206D301R-10 is 0.043" (1.10mm), and BLA31BD221SN4D is 0.039" (1.00mm). Verify PCB assembly clearance requirements for the substitute part height.

Q: What is the difference between bulk and Tape & Reel packaging?

A: DA1206D301R-00 is supplied in bulk packaging, while DA1206D301R-10 and BLA31BD221SN4D are supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes and is the preferred format for production quantities.

Q: Are there regulatory compliance differences between these parts?

A: Yes. DA1206D301R-00 is RoHS non-compliant. Both DA1206D301R-10 and BLA31BD221SN4D are ROHS3 compliant. For new designs and production requiring RoHS compliance, either active substitute is appropriate.

Q: Can BLA31BD221SN4D be used in power-line applications?

A: No. The BLA31BD221SN4D is designated for signal-line applications only. The DA1206D301R-10 is specified for both power and signal-line applications and maintains the 400mA current rating required for power-line filtering.
