SQCB5C104MATME Equivalent & Substitute Parts

Part Overview

The SQCB5C104MATME is a 0.1 µF ceramic capacitor rated at 50V with ±20% tolerance, manufactured by KYOCERA AVX in the SQ series. This component is classified as obsolete, making identification of suitable alternatives essential for ongoing production and maintenance applications. The part features high Q and low loss characteristics, making it suitable for RF and microwave applications. Due to its obsolete status, equivalent or upgraded substitutes must be evaluated based on electrical specifications and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SQCB5C104MATME is determined by the following critical parameters:

• Capacitance Value: Must be 0.1 µF (exact match required)
• Voltage Rating: Must be 50V or higher
• Package / Case: Must be 1111 (2828 Metric) for mechanical compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Physical Dimensions: Must match 0.110" L x 0.110" W and 0.102" maximum thickness
• Temperature Coefficient: C-type acceptable for RF/microwave applications
• Operating Temperature Range: Must support -55°C minimum; 175°C operation preferred for full compatibility
• Tolerance: ±20% or tighter acceptable
• MSL Rating: Must be 1 (Unlimited) or equivalent

Two substitute parts meet these criteria with varying compliance and performance characteristics.

Engineering Selection Recommendations

SQCB5C104KA1ME (KYOCERA AVX Upgrade)

This part is the direct upgrade from the obsolete SQCB5C104MATME. It maintains identical electrical specifications (0.1 µF, 50V, C temperature coefficient) and mechanical compatibility (1111 package, identical dimensions). The upgrade offers improved tolerance (±10% versus ±20%), maintaining full operating temperature range (-55°C ~ 175°C). The part is currently in active production status. However, this substitute is RoHS non-compliant, which may present regulatory constraints depending on application requirements and regional compliance mandates.

200B104MT50XT1K (American Technical Ceramics Alternative)

This part provides full electrical and mechanical compatibility with identical capacitance (0.1 µF), voltage rating (50V), tolerance (±20%), and package dimensions (1111, 2828 Metric). It is ROHS3 compliant and maintains MSL 1 rating. The primary limitation is the reduced operating temperature range (-55°C ~ 125°C versus -55°C ~ 175°C), which restricts use in applications requiring sustained operation above 125°C. This part is actively manufactured and available in Tape & Reel packaging. The temperature coefficient is BX rather than C, reflecting different dielectric material characteristics suitable for bypass and decoupling applications.

For applications requiring full temperature range operation and RoHS3 compliance, neither substitute provides complete feature parity. Selection should prioritize application-specific temperature requirements and regulatory compliance mandates.

Frequently Asked Questions (FAQ)

Q: Can SQCB5C104KA1ME be used as a direct replacement for SQCB5C104MATME?

A: Yes, from an electrical and mechanical standpoint. Both parts share identical capacitance (0.1 µF), voltage rating (50V), package (1111), and operating temperature range (-55°C ~ 175°C). The SQCB5C104KA1ME offers tighter tolerance (±10%). However, the substitute is RoHS non-compliant, which may conflict with procurement or regulatory requirements.

Q: What is the key difference between the two substitute options?

A: SQCB5C104KA1ME is a direct upgrade from the same manufacturer (KYOCERA AVX) with improved tolerance but RoHS non-compliance. The 200B104MT50XT1K from American Technical Ceramics is ROHS3 compliant but has a reduced maximum operating temperature (125°C versus 175°C) and different temperature coefficient (BX versus C).

Q: Are the physical dimensions identical across all three parts?

A: Yes. All three parts use the 1111 (2828 Metric) package with dimensions of 0.110" L x 0.110" W (2.79mm x 2.79mm) and maximum thickness of 0.102" (2.59mm). They are mechanically interchangeable on PCBs designed for this footprint.

Q: Which substitute should I select for high-temperature applications?

A: SQCB5C104KA1ME supports the full operating range of -55°C ~ 175°C, matching the original part. The 200B104MT50XT1K is limited to -55°C ~ 125°C and is unsuitable for applications requiring sustained operation above 125°C.

Q: Does RoHS compliance matter for my application?

A: RoHS compliance is a regulatory requirement in many jurisdictions and for certain end-use applications. SQCB5C104KA1ME is RoHS non-compliant, while 200B104MT50XT1K is ROHS3 compliant. Verify your application's compliance requirements before selection.

Q: Are all three parts available in the same packaging format?

A: The original SQCB5C104MATME and SQCB5C104KA1ME packaging is not specified in the provided data. The 200B104MT50XT1K is available in Tape & Reel (TR) format. Confirm packaging requirements with your procurement process.
