Substitute Part Grouping Explanation

Substitution eligibility for the DLW5BTM101SQ2L is determined by strict alignment of the following critical parameters:

• Impedance @ Frequency: Must match 100 Ohms @ 100 MHz
• Number of Lines: Must be 2-line configuration
• Mounting Type: Must be Surface Mount
• Voltage Rating - DC: Must meet or exceed 50V
• Current Rating (Max): Must meet or exceed 6A
• DC Resistance (DCR): Must not exceed 13mOhm maximum
• Package / Case: Must be Horizontal, 4 PC Pad configuration
• Physical Dimensions: Length and width must be compatible with 5.00mm x 5.00mm footprint; height must not exceed 0.098" (2.50mm)
• RoHS Compliance: Must maintain ROHS3 Compliant status

The SPDL485025-100-2P-T from Signal Transformer meets all substitution criteria and is classified as a manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

The SPDL485025-100-2P-T is a direct substitute for the discontinued DLW5BTM101SQ2L. Both components maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage protocols. The substitute part offers improved electrical performance with lower DC resistance (9mOhm typical versus 13mOhm maximum) and higher current capacity (6.5A versus 6A), while maintaining identical impedance characteristics and footprint compatibility. The extended operating temperature range of the substitute (-40°C to 125°C versus -40°C to 85°C) provides additional thermal margin for demanding applications. Physical dimensions are compatible within PCB layout tolerances, with the substitute width of 4.80mm fitting within the original 5.00mm specification.

Frequently Asked Questions (FAQ)

Q: Can the SPDL485025-100-2P-T be used as a direct replacement for the DLW5BTM101SQ2L?

A: Yes. Both components share identical impedance (100 Ohms @ 100 MHz), line configuration (2-line), mounting type (surface mount), voltage rating (50V DC), and package geometry (Horizontal, 4 PC Pad). The substitute meets or exceeds all electrical specifications of the original part.

Q: What are the key differences between these two parts?

A: The SPDL485025-100-2P-T provides superior electrical performance with lower DC resistance (9mOhm typical versus 13mOhm maximum) and higher current capacity (6.5A versus 6A). The substitute also features an extended operating temperature range (-40°C to 125°C versus -40°C to 85°C). Physical width is slightly reduced (4.80mm versus 5.00mm), which remains compatible with the original footprint.

Q: Are there any compliance or certification differences?

A: Both parts maintain ROHS3 compliance and MSL 1 rating. The substitute is REACH Affected, whereas the original part is REACH Unaffected. Verify REACH compliance requirements for your specific application and end-use region.

Q: Will the substitute part fit the existing PCB layout?

A: Yes. The substitute dimensions (5.00mm L x 4.80mm W x 2.50mm H) are compatible with the original footprint (5.00mm L x 5.00mm W x 2.50mm H). The reduced width of 4.80mm fits within the original 5.00mm specification, and all other dimensions are identical.

Q: What is the product status of each part?

A: The DLW5BTM101SQ2L is discontinued at DiGi Electronics. The SPDL485025-100-2P-T is active and available for procurement.
