AQ11EM101KA7ME Equivalent & Substitute Parts

Part Overview

The AQ11EM101KA7ME is a 100 pF ceramic capacitor manufactured by KYOCERA AVX, rated for 150V operation in a 0505 (1313 Metric) surface mount package. This component is designed for RF, microwave, and high-frequency applications. The part is currently obsolete, making equivalent substitute parts necessary for ongoing production and maintenance requirements. Substitute parts maintain identical capacitance, voltage rating, package dimensions, and operating temperature range while offering improved tolerance specifications and active product status.

Substitute Part Grouping Explanation

Substitute parts for the AQ11EM101KA7ME are qualified based on the following criteria:

Mandatory Matching Parameters:

• Capacitance: 100 pF (exact match required)
• Voltage Rating: 150V (exact match required)
• Temperature Coefficient: M (exact match required)
• Operating Temperature Range: -55°C ~ 175°C (exact match required)
• Package / Case: 0505 (1313 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Physical Dimensions: 0.055" L x 0.055" W (1.40mm x 1.40mm) (exact match required)
• Thickness (Max): 0.057" (1.45mm) (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)
• REACH Status: REACH Unaffected (exact match required)

Variable Parameter:

• Tolerance: Substitute parts offer tighter tolerance specifications (±1%, ±2%, ±5%) compared to the original ±10% tolerance. All substitute parts maintain electrical and mechanical compatibility while providing improved precision for applications requiring tighter capacitance control.

All substitute parts are manufactured by KYOCERA AVX within the AQ series and maintain full compatibility with the original part's electrical performance envelope and physical footprint.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (AQ11EM101FA1WE, AQ11EM101GA1BE, AQ11EM101JA1BE) are direct functional equivalents to the AQ11EM101KA7ME. Selection among substitutes depends on application tolerance requirements:

AQ11EM101FA1WE (±1% Tolerance): Select for applications requiring the tightest capacitance control. Active product status ensures long-term availability and supply chain continuity. ROHS3 compliance and REACH unaffected status meet current regulatory requirements.

AQ11EM101GA1BE (±2% Tolerance): Select for applications requiring moderate capacitance precision. Active product status with highest inventory availability (945 Pcs) supports production volume requirements. Full regulatory compliance maintained.

AQ11EM101JA1BE (±5% Tolerance): Select for applications where the original ±10% tolerance specification is acceptable but active product status is required. Highest inventory level (1155 Pcs) provides optimal supply availability. Maintains all regulatory certifications.

All substitute parts maintain identical electrical performance within their respective tolerance bands and are fully compatible with existing PCB layouts and assembly processes designed for the 0505 package footprint.

Frequently Asked Questions (FAQ)

Q: Can AQ11EM101FA1WE, AQ11EM101GA1BE, or AQ11EM101JA1BE be used as direct replacements for AQ11EM101KA7ME?

A: Yes. All three parts are direct functional equivalents. They maintain identical capacitance (100 pF), voltage rating (150V), temperature coefficient (M), operating temperature range (-55°C ~ 175°C), package dimensions (0505 / 1313 Metric), and physical footprint. The only difference is tolerance specification, which is tighter in all substitute parts.

Q: What is the tolerance difference between the original and substitute parts?

A: The original AQ11EM101KA7ME has ±10% tolerance. Substitute parts offer ±1% (AQ11EM101FA1WE), ±2% (AQ11EM101GA1BE), or ±5% (AQ11EM101JA1BE) tolerance. Tighter tolerance means the actual capacitance value will be closer to the nominal 100 pF specification.

Q: Are all substitute parts ROHS3 compliant and REACH unaffected?

A: Yes. All substitute parts maintain ROHS3 compliance and REACH unaffected status, identical to the original part.

Q: Will the substitute parts fit the same PCB layout?

A: Yes. All substitute parts use the identical 0505 (1313 Metric) package with matching physical dimensions (0.055" L x 0.055" W / 1.40mm x 1.40mm) and maximum thickness (0.057" / 1.45mm). No PCB redesign is required.

Q: What is the Moisture Sensitivity Level (MSL) for substitute parts?

A: All substitute parts have MSL 1 (Unlimited), identical to the original part. This indicates unlimited shelf life under normal storage conditions without special moisture control requirements.

Q: Why is the original AQ11EM101KA7ME marked as obsolete?

A: The original part is obsolete but substitute parts from the same AQ series are active and available. Active product status ensures continued manufacturing, quality control, and supply chain availability for future production needs.
