7M19270004 Crystal Equivalent & Substitute Parts

Part Overview

The 7M19270004 is a 19.2 MHz surface mount crystal oscillator manufactured by TXC CORPORATION. This component operates at a frequency of 19.2 MHz with a frequency stability of ±30ppm and a load capacitance of 18pF. The part is housed in a 4-SMD, No Lead package with dimensions of 3.20mm x 2.50mm and a maximum seated height of 0.80mm. The 7M19270004 maintains Active product status and is RoHS Compliant with MSL Level 1 (Unlimited moisture sensitivity). Identifying equivalent and substitute parts is necessary when the primary part number is unavailable, when inventory constraints require alternative sourcing, or when design flexibility permits component optimization within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7M19270004 is determined by strict equivalence across the following critical parameters: frequency (19.2 MHz), frequency stability (±30ppm), load capacitance (18pF), package type (4-SMD, No Lead), operating temperature range (-20°C ~ 70°C), and compliance certifications (RoHS Compliant, MSL Level 1). The substitute part 8Y-19.200MAAJ-T meets all these requirements. Physical dimensions and ESR specifications may vary within acceptable mechanical and electrical tolerances for surface mount crystal applications. Both parts are manufactured by TXC CORPORATION and maintain Active product status, ensuring continued availability and technical support.

Parameter Comparison

Engineering Selection Recommendations

The 8Y-19.200MAAJ-T serves as a direct electrical substitute for the 7M19270004 based on matching frequency, frequency stability, load capacitance, operating temperature range, and compliance certifications. Both parts are Active products from TXC CORPORATION with RoHS Compliance and MSL Level 1 ratings. The 8Y-19.200MAAJ-T features a smaller physical footprint (2.00mm x 1.60mm versus 3.20mm x 2.50mm) and lower maximum seated height (0.55mm versus 0.80mm), which may provide advantages in space-constrained applications. The 8Y-19.200MAAJ-T specifies an ESR of 100 Ohms, whereas the 7M19270004 does not provide this specification. Selection between these parts depends on PCB layout requirements and available board space. Both parts are suitable for applications requiring 19.2 MHz crystal oscillation with ±30ppm stability and 18pF load capacitance.

Frequently Asked Questions (FAQ)

Q: Can the 8Y-19.200MAAJ-T replace the 7M19270004 in existing designs?

A: Yes, the 8Y-19.200MAAJ-T is electrically equivalent to the 7M19270004. Both parts operate at 19.2 MHz with ±30ppm frequency stability and 18pF load capacitance. Physical dimensions differ, with the 8Y-19.200MAAJ-T being smaller. PCB layout modifications may be necessary to accommodate the different footprint dimensions.

Q: What are the key electrical parameters that determine substitutability?

A: The critical parameters are frequency (19.2 MHz), frequency stability (±30ppm), load capacitance (18pF), and operating temperature range (-20°C ~ 70°C). Both parts match these specifications exactly.

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

A: No. Both the 7M19270004 and 8Y-19.200MAAJ-T are RoHS Compliant with MSL Level 1 (Unlimited) ratings. Both are REACH Unaffected and classified as EAR99 for export control purposes.

Q: What is the significance of the ESR specification on the 8Y-19.200MAAJ-T?

A: The 8Y-19.200MAAJ-T specifies an ESR (Equivalent Series Resistance) of 100 Ohms. The 7M19270004 does not provide this specification in the available data. ESR affects circuit performance and power consumption. Verify that the 100 Ohms ESR is compatible with your circuit design requirements.

Q: Do the physical dimension differences affect PCB compatibility?

A: Yes. The 8Y-19.200MAAJ-T (2.00mm x 1.60mm, 0.55mm height) is smaller than the 7M19270004 (3.20mm x 2.50mm, 0.80mm height). If using the 8Y-19.200MAAJ-T as a substitute, confirm that the smaller footprint is compatible with your PCB layout and that no mechanical interference occurs with adjacent components.

Q: Are both parts currently available?

A: Both parts maintain Active product status. The 7M19270004 has 939 pieces in stock, and the 8Y-19.200MAAJ-T has 3562 pieces in stock as new original inventory.
