Frequency Stability: ±60 ppm (exact match required)
Load Capacitance: 8 pF (exact match required)
ESR: 60 Ohms (exact match required)
Operating Mode: Fundamental (exact match required)

Mechanical & Environmental Parameters:

Operating Temperature Range: -40°C to 125°C (exact match required)
Package / Case: 4-SMD, No Lead (exact match required)

Engineering Selection Recommendations

Both the 7V-25.000MAKV-T and 7M-25.000MAKV-T are active products manufactured by TXC CORPORATION with identical electrical specifications and mechanical compatibility. The parts differ only in series designation (7V versus 7M) and seated height (0.90mm versus 0.80mm).

The 7M-25.000MAKV-T substitute part exhibits a lower maximum seated height of 0.80mm compared to the main part's 0.90mm specification. This dimensional difference is compatible with applications where the main part is specified, as the substitute occupies less vertical space on the PCB.

Both parts maintain RoHS compliance and MSL Level 1 (Unlimited) moisture sensitivity rating. Selection between these parts should be based on availability, inventory status, and specific PCB layout constraints related to component height.

Frequently Asked Questions (FAQ)

Q: Can the 7M-25.000MAKV-T be used as a direct replacement for the 7V-25.000MAKV-T?

A: Yes. The 7M-25.000MAKV-T is electrically and mechanically equivalent to the 7V-25.000MAKV-T across all critical parameters including frequency, load capacitance, ESR, operating temperature range, and package specifications. The substitute part has a lower seated height (0.80mm versus 0.90mm), which is compatible with applications designed for the main part.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by exact equivalence in frequency (25.0000 MHz), frequency tolerance (±30 ppm), frequency stability (±60 ppm), load capacitance (8 pF), ESR (60 Ohms), operating temperature range (-40°C to 125°C), package type (4-SMD, No Lead), and physical dimensions (3.20mm x 2.50mm). All these parameters must match exactly.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the 7V-25.000MAKV-T and 7M-25.000MAKV-T are RoHS Compliant, REACH Unaffected, and classified under ECCN EAR99. Both carry MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: What is the difference between the 7V and 7M series designations?

A: The series designation indicates the product line within TXC CORPORATION's crystal oscillator portfolio. Both series meet identical electrical and mechanical specifications for this 25 MHz crystal application. The designation difference does not affect functional performance or compatibility.

Q: Can height differences affect PCB assembly or functionality?

A: The 7M-25.000MAKV-T's lower seated height (0.80mm) compared to the 7V-25.000MAKV-T (0.90mm) does not affect electrical functionality. Height differences are relevant only for PCB layout and assembly clearance considerations. The substitute part requires less vertical space and is compatible with designs specified for the main part.
