Substitute Part Grouping Explanation

Substitution eligibility for the 28L0138-70R is determined by strict equivalence across the following critical parameters:

• Impedance Specification: 220 Ohms @ 100 MHz
• Current Rating: 5A maximum
• DC Resistance: 10 mOhm maximum
• Number of Lines: 1 (single-line configuration)
• Package Type: Axial
• Mounting Technology: Through Hole
• Physical Dimensions: 0.138" Dia x 0.550" L (3.51mm x 13.97mm)
• Manufacturer Series: 28

The substitute part 28L0138-70R-10 meets all electrical and mechanical parameters required for direct substitution. The primary distinction between the main part and its substitute is product status and packaging format, not functional or dimensional characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 28L0138-70R-10 is the direct substitute for the obsolete 28L0138-70R. Both components are manufactured by Laird-Signal Integrity Products within the same Series 28 product line and share identical electrical specifications and physical dimensions.

Product Status Consideration: The 28L0138-70R carries obsolete status, while the 28L0138-70R-10 maintains active product status. This distinction reflects current manufacturing availability and long-term supply chain viability.

Compliance Status: The 28L0138-70R-10 is ROHS3 compliant, whereas the original part is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the substitute part satisfies compliance obligations.

Packaging and Inventory: The 28L0138-70R-10 is supplied in Cut Tape (CT) packaging format with significantly higher inventory availability (24,409 pieces versus 896 pieces). This packaging format is standard for automated assembly processes and high-volume production environments.

Frequently Asked Questions (FAQ)

Q: Can the 28L0138-70R-10 be used as a direct replacement for the 28L0138-70R?

A: Yes. Both components are electrically and mechanically identical. The 28L0138-70R-10 provides the same 220 ohms impedance at 100 MHz, 5A current rating, and 10 mOhm DC resistance in the same axial through-hole package with identical dimensions.

Q: What is the difference between the two part numbers?

A: The primary differences are product status (obsolete versus active), packaging format (bulk versus cut tape), and regulatory compliance (RoHS non-compliant versus ROHS3 compliant). Electrical and mechanical specifications are identical.

Q: Is the cut tape packaging compatible with my through-hole assembly process?

A: Cut tape packaging is standard for automated component placement and manual insertion processes. The physical component dimensions and lead configuration remain unchanged from the original part.

Q: Does the ROHS3 compliance of the substitute part affect circuit performance?

A: No. ROHS3 compliance relates to material composition and environmental regulations, not electrical performance. The impedance, current rating, and DC resistance specifications remain identical.

Q: Are there any thermal or frequency response differences between these parts?

A: No differences are specified in the provided parameters. Both components maintain the same impedance specification of 220 ohms at 100 MHz and identical DC resistance characteristics.
