Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7M20000089 is determined by the following critical parameters:

Primary Matching Criteria:

• Frequency: 20 MHz (exact match required)
• Frequency Stability: ±30ppm (exact match required)
• Operating Temperature Range: -20°C ~ 70°C (exact match required)
• Package Type: 4-SMD, No Lead (exact match required)
• Mounting Type: Surface Mount (exact match required)

Secondary Compatibility Criteria:

• Load Capacitance: 18pF nominal (substitutes with 16pF or 20pF are acceptable within standard crystal design tolerances)
• RoHS Compliance: Required
• MSL Rating: 1 (Unlimited) or equivalent
• Product Status: Active

Substitute parts are grouped into two categories based on load capacitance deviation and ESR (Equivalent Series Resistance) specifications:

Group 1 - TXC CORPORATION Series (Same Manufacturer): Parts 7M-20.000MAAJ-T and 8Z-20.000MAAJ-T maintain identical frequency, stability, and load capacitance specifications with documented ESR values (60 Ohms and 100 Ohms respectively). These parts differ in packaging format and physical dimensions.

Group 2 - Raltron Electronics Series (Alternative Manufacturer): Parts RH100-20.000-16-3030-TR and RH100-20.000-20-3030-TR provide equivalent frequency and stability with load capacitance values of 16pF and 20pF respectively, representing ±2pF deviation from the 18pF specification. Both maintain 70 Ohms ESR and identical operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Preferred for Pin-Compatible Replacement):

7M-20.000MAAJ-T is the primary equivalent substitute for 7M20000089. Both parts are manufactured by TXC CORPORATION, share identical frequency (20 MHz), frequency stability (±30ppm), load capacitance (18pF), operating temperature range (-20°C ~ 70°C), and physical dimensions (3.20mm x 2.50mm). The primary difference is packaging format (Tape & Reel vs. unspecified bulk packaging). This part maintains RoHS Compliance and MSL 1 rating with Active product status. ESR specification of 60 Ohms is documented for this variant.

Alternative from Same Manufacturer (Compact Form Factor):

8Z-20.000MAAJ-T provides equivalent electrical specifications (20 MHz, ±30ppm, 18pF load capacitance) with higher ESR (100 Ohms) and reduced physical dimensions (2.50mm x 2.00mm, 0.55mm height). This variant is suitable for space-constrained applications where the smaller footprint is advantageous. All compliance certifications and operating temperature range remain identical.

Cross-Manufacturer Alternatives (Load Capacitance Variants):

RH100-20.000-16-3030-TR and RH100-20.000-20-3030-TR from Raltron Electronics provide equivalent frequency (20 MHz) and frequency stability (±30ppm) with load capacitance values of 16pF and 20pF respectively. These represent ±2pF deviation from the 18pF specification and are acceptable substitutes where circuit design accommodates load capacitance tolerance. Both maintain 70 Ohms ESR, identical operating temperature range, and ROHS3 Compliance. Physical dimensions match the primary part (3.20mm x 2.50mm, 0.80mm height) except RH100-20.000-16-3030-TR is supplied in Cut Tape format.

Selection Criteria:

• For direct replacement with identical specifications: Select 7M-20.000MAAJ-T
• For space-constrained PCB layouts: Select 8Z-20.000MAAJ-T
• For alternative manufacturer sourcing with load capacitance tolerance: Select RH100-20.000-20-3030-TR (20pF) or RH100-20.000-16-3030-TR (16pF)
• For bulk purchasing with tape packaging: Select 7M-20.000MAAJ-T or RH100-20.000-20-3030-TR

All substitute parts maintain Active product status and full RoHS compliance, ensuring long-term availability and regulatory conformance.

Frequently Asked Questions (FAQ)

Q: Can 7M-20.000MAAJ-T be used as a direct replacement for 7M20000089?

A: Yes. Both parts share identical electrical specifications (20 MHz frequency, ±30ppm stability, 18pF load capacitance) and physical dimensions (3.20mm x 2.50mm). The primary difference is packaging format. Electrical performance and PCB compatibility are equivalent.

Q: What is the significance of load capacitance in crystal substitution?

A: Load capacitance determines the crystal's resonant frequency in a specific circuit configuration. The 7M20000089 specifies 18pF load capacitance. Substitute parts with 16pF or 20pF load capacitance (RH100 series) represent ±2pF deviation and are acceptable where circuit design accommodates this tolerance. Exact load capacitance matching is preferred for precision timing applications.

Q: Why does 8Z-20.000MAAJ-T have different physical dimensions?

A: The 8Z-20.000MAAJ-T is a compact variant (2.50mm x 2.00mm, 0.55mm height) compared to the standard 3.20mm x 2.50mm footprint. This smaller form factor is achieved through alternative internal design while maintaining identical electrical specifications. PCB layout compatibility must be verified before selection.

Q: What is ESR and how does it affect substitution?

A: ESR (Equivalent Series Resistance) represents the crystal's internal resistance at the operating frequency. The 7M20000089 does not specify ESR, while substitutes range from 60 Ohms (7M-20.000MAAJ-T) to 100 Ohms (8Z-20.000MAAJ-T) to 70 Ohms (RH100 series). ESR affects circuit startup time and power consumption. Substitutes with documented ESR values are acceptable where circuit design accommodates the specified range.

Q: Are Raltron Electronics RH100 series crystals compatible with TXC CORPORATION designs?

A: RH100-20.000-16-3030-TR and RH100-20.000-20-3030-TR provide equivalent frequency (20 MHz) and frequency stability (±30ppm) with load capacitance variants (16pF and 20pF). These are acceptable substitutes where circuit design accommodates ±2pF load capacitance tolerance. All parts maintain identical operating temperature range (-20°C ~ 70°C) and RoHS compliance.

Q: What packaging format differences exist among substitute parts?

A: 7M20000089 packaging format is not specified. 7M-20.000MAAJ-T and RH100-20.000-20-3030-TR are supplied in Tape & Reel (TR) format for automated assembly. RH100-20.000-16-3030-TR is supplied in Cut Tape (CT) format. Packaging format affects handling and assembly processes but does not impact electrical performance or compatibility.

Q: Can I substitute a 16pF crystal for an 18pF specification?

A: RH100-20.000-16-3030-TR provides 16pF load capacitance, representing -2pF deviation from the 18pF specification. This is acceptable where circuit design accommodates load capacitance tolerance. The crystal will operate at the specified 20 MHz frequency with ±30ppm stability. Circuit validation is required to confirm frequency accuracy within the application's tolerance requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. The 7M20000089 is RoHS Compliant. All substitute parts (7M-20.000MAAJ-T, 8Z-20.000MAAJ-T, RH100-20.000-16-3030-TR, RH100-20.000-20-3030-TR) are either RoHS Compliant or ROHS3 Compliant, meeting regulatory requirements for electronic component manufacturing and assembly.

Q: What is MSL rating and why is it important?

A: MSL (Moisture Sensitivity Level) rating indicates the component's sensitivity to moisture absorption during storage and handling. All listed parts maintain MSL 1 (Unlimited) rating, indicating minimal moisture sensitivity and no special storage or handling requirements. This ensures consistent reliability across all substitute options.
