7M-20.000MAHV-T Equivalent & Substitute Parts

Part Overview

The 7M-20.000MAHV-T is a 20 MHz fundamental mode crystal oscillator manufactured by TXC CORPORATION. This surface mount device operates across the industrial temperature range of -40°C to 85°C and is specified for 8pF load capacitance with 60 Ohms equivalent series resistance. The part is actively produced and RoHS compliant, making it suitable for modern electronic applications requiring precise frequency reference. Substitute parts are identified for applications where alternative manufacturers, packaging formats, or load capacitance specifications are required while maintaining core frequency and stability parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7M-20.000MAHV-T is determined by the following critical parameters:

Primary Matching Criteria:

• Frequency: 20.0000 MHz (exact match required)
• Frequency Stability: ±30 ppm (exact match required)
• Operating Mode: Fundamental (exact match required)
• Operating Temperature Range: -40°C to 85°C (exact match required)
• Package Type: 4-SMD, No Lead (exact match required)

Secondary Compatibility Parameters:

• Load Capacitance: 8 pF (primary specification; 10 pF variants acceptable with circuit design verification)
• ESR: 60 Ohms (primary specification; variations within 70 Ohms acceptable)
• Mounting Type: Surface Mount (exact match required)
• MSL Rating: 1 or equivalent (exact match required)

Identified Substitute Parts:

1. RH100-20.000-8-3030-EXT-TR (Raltron Electronics): Matches all primary criteria with identical load capacitance (8 pF) and comparable ESR (70 Ohms). Available in Tape & Reel packaging.

2. R2016-20.000-10-3030-EXT-TR (Raltron Electronics): Matches all primary criteria with alternative load capacitance (10 pF) and higher ESR (200 Ohms). Smaller physical footprint (2.00 × 1.60 mm).

Parameter Comparison

Engineering Selection Recommendations

RH100-20.000-8-3030-EXT-TR Selection Criteria:

This substitute is the closest functional equivalent to the 7M-20.000MAHV-T. Both parts share identical load capacitance (8 pF), matching physical dimensions (3.20 × 2.50 × 0.80 mm), and equivalent series resistance within acceptable tolerance (70 Ohms versus 60 Ohms). The RH100 series is ROHS3 compliant and maintains the same operating temperature range. The primary difference is packaging format (Tape & Reel versus Cut Tape), which affects procurement and assembly processes but not electrical performance. This part is suitable for direct substitution in applications where Raltron Electronics components are approved.

R2016-20.000-10-3030-EXT-TR Selection Criteria:

This substitute provides an alternative for applications with space constraints due to its reduced physical footprint (2.00 × 1.60 × 0.50 mm). However, the 10 pF load capacitance and 200 Ohms ESR represent significant deviations from the primary specification. Selection of this part requires verification that the circuit design accommodates the alternative load capacitance value and higher series resistance. The R2016 is ROHS3 compliant and maintains the required operating temperature range. This part is suitable only when circuit design parameters explicitly allow for 10 pF load capacitance operation.

Compliance Considerations:

All identified substitutes maintain RoHS and REACH compliance status equivalent to or exceeding the original part specification. MSL ratings are uniform across all parts (Level 1, Unlimited), eliminating moisture sensitivity as a selection factor.

Frequently Asked Questions (FAQ)

Q: Can the RH100-20.000-8-3030-EXT-TR be used as a direct replacement for the 7M-20.000MAHV-T?

A: Yes. Both parts operate at 20.0000 MHz with ±30 ppm stability, 8 pF load capacitance, and identical physical dimensions. The ESR difference (70 Ohms versus 60 Ohms) is within acceptable tolerance for most applications. The primary consideration is packaging format: RH100 is supplied in Tape & Reel format while the 7M is supplied in Cut Tape format.

Q: What is the significance of the load capacitance difference between the 8 pF and 10 pF variants?

A: Load capacitance determines the oscillation frequency in the circuit. The 7M-20.000MAHV-T and RH100-20.000-8-3030-EXT-TR are both specified for 8 pF load capacitance. The R2016-20.000-10-3030-EXT-TR operates at 10 pF load capacitance. Substituting a 10 pF part into a circuit designed for 8 pF will result in frequency deviation. Use of the R2016 requires circuit redesign or verification that the application tolerates the frequency shift.

Q: How does ESR (Equivalent Series Resistance) affect crystal selection?

A: ESR influences the crystal's ability to start oscillation and its power consumption in the circuit. The 7M-20.000MAHV-T specifies 60 Ohms ESR, while the RH100 specifies 70 Ohms. This 10 Ohm difference is typically acceptable in standard applications. The R2016 specifies 200 Ohms ESR, which is significantly higher and may affect circuit startup characteristics or power consumption. Verification is required before substitution.

Q: Are there packaging considerations when substituting the RH100 for the 7M?

A: Yes. The 7M-20.000MAHV-T is supplied in Cut Tape (CT) packaging, while the RH100-20.000-8-3030-EXT-TR is supplied in Tape & Reel (TR) format. Both are surface mount compatible, but procurement, handling, and assembly processes differ. Tape & Reel format is typically used for high-volume automated assembly, while Cut Tape is used for lower volumes or manual assembly.

Q: Can the R2016-20.000-10-3030-EXT-TR be used in applications designed for the 7M-20.000MAHV-T?

A: Only with circuit design verification. The R2016 has a smaller physical footprint (2.00 × 1.60 mm versus 3.20 × 2.50 mm), 10 pF load capacitance (versus 8 pF), and 200 Ohms ESR (versus 60 Ohms). The load capacitance difference will cause frequency deviation unless the circuit is redesigned to compensate. The higher ESR may affect oscillation startup. This part is suitable only when these parameters are explicitly accommodated in the circuit design.

Q: Do all substitute parts meet the same compliance standards as the original part?

A: All identified substitutes maintain RoHS and REACH compliance. The 7M-20.000MAHV-T is RoHS Compliant, while both Raltron substitutes are ROHS3 Compliant, which represents an equivalent or higher standard. MSL ratings are uniform (Level 1, Unlimited) across all parts.
