Substitute Part Grouping Explanation

Substitution of the PLH10AS2911R2P2B is based on the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Number of Lines: 2 (maintains dual-line common mode filtering)
• Current Rating: 1.2A maximum (ensures thermal and magnetic performance equivalence)
• Voltage Rating - DC: 250V minimum (maintains voltage withstand capability)
• Filter Type: Power Line (ensures application-specific design)
• Mounting Type: Through Hole (maintains PCB assembly compatibility)

Mechanical Compatibility Criteria:

• Package / Case: Vertical, 4 PC Pin (ensures footprint and pin configuration compatibility)
• Moisture Sensitivity Level: 1 or Not Applicable (ensures handling and storage compatibility)

Regulatory and Compliance Criteria:

• REACH Status: REACH Unaffected or compliant status
• ECCN: EAR99 (maintains export classification consistency)

The SSR21HS-12115 manufactured by KEMET meets all substitution criteria and is classified as an active product with current availability.

Parameter Comparison

Engineering Selection Recommendations

The SSR21HS-12115 is the manufacturer-recommended substitute for the obsolete PLH10AS2911R2P2B. Both components share identical electrical ratings for current (1.2A) and voltage (250V DC), maintaining functional equivalence in power line filtering applications.

The SSR21HS-12115 offers the following advantages:

• Active Product Status: Currently manufactured and available, ensuring long-term supply chain continuity
• Enhanced Temperature Range: Operating temperature extends to 120°C, providing broader thermal performance margin compared to the original 60°C maximum
• RoHS3 Compliance: Meets current environmental and hazardous substance restrictions
• Specified DC Resistance: 270mOhm DCR provides documented electrical performance

Physical dimensions differ between the two components. The SSR21HS-12115 is larger in length and width (23.00mm x 23.00mm versus 18.00mm x 16.00mm) but shorter in height (14.50mm versus 17.50mm). PCB layout modifications may be required to accommodate the footprint change.

Both components maintain identical export classification (EAR99) and REACH compliance status, ensuring regulatory consistency.

Frequently Asked Questions (FAQ)

Q: Can the SSR21HS-12115 directly replace the PLH10AS2911R2P2B without circuit modifications?

A: Electrical substitution is direct. Both components are 2-line common mode chokes rated for 1.2A at 250V DC with identical pin configurations (Vertical, 4 PC Pin). PCB layout modifications are required due to different physical dimensions.

Q: What is the significance of the 270mOhm DC resistance specification on the SSR21HS-12115?

A: DC resistance (DCR) defines the resistive losses in the component during operation. The 270mOhm specification for the SSR21HS-12115 is a documented electrical parameter. The original PLH10AS2911R2P2B does not provide a specified DCR value.

Q: Does the larger physical size of the SSR21HS-12115 affect electrical performance?

A: Physical size differences do not alter the electrical substitution relationship. Both components meet the same current and voltage ratings. Size differences reflect manufacturing design variations between Murata and KEMET. PCB layout must accommodate the larger footprint.

Q: Is the extended operating temperature range of the SSR21HS-12115 (-25°C to 120°C) a requirement for substitution?

A: No. The extended temperature range is an additional capability of the SSR21HS-12115. If the application operates within the original -25°C to 60°C range, both components perform equivalently. The extended range provides additional design margin.

Q: Are there any compliance or regulatory differences between these components?

A: Both components share identical REACH and ECCN classifications (REACH Unaffected, EAR99). The SSR21HS-12115 includes RoHS3 compliance certification, which is not specified for the original component. This represents an environmental compliance advantage.

Q: What inventory considerations apply to this substitution?

A: The PLH10AS2911R2P2B is obsolete with limited remaining stock (1105 pcs). The SSR21HS-12115 is an active product with current availability (887 pcs in stock). New designs should specify the SSR21HS-12115 to ensure long-term supply continuity.
