Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7V-12.288MDHV-T are qualified based on electrical and mechanical parameter equivalence. The substitution criteria are:

Frequency matching at 12.288 MHz with identical tolerance (±20ppm) and stability (±30ppm) specifications ensures functional compatibility in frequency-dependent circuits. Load capacitance of 8pF and ESR of 100 Ohms must remain constant to maintain circuit performance and oscillation characteristics. Operating mode (Fundamental) and temperature range (-40°C to 85°C) define the operational envelope. Package configuration (4-SMD, No Lead) and physical dimensions (3.20mm x 2.50mm) ensure mechanical compatibility with PCB layouts and automated assembly processes. Surface mount mounting type and Tape & Reel packaging format maintain assembly compatibility.

Two substitute parts meet these criteria:

ECS-122.8-8-33-JGN-TR (ECS Inc., ECX-32 series) qualifies as a direct manufacturer equivalent with identical electrical specifications and RoHS3 compliance.

STDCRG2-12.288M (NDK America, Inc., NX3225GA series) qualifies as a parametric equivalent with matching electrical and mechanical specifications and RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and meet RoHS compliance requirements. The 7V-12.288MDHV-T and STDCRG2-12.288M are both RoHS Compliant, while ECS-122.8-8-33-JGN-TR carries RoHS3 Compliant certification with additional REACH Unaffected status. Height variation between ECS-122.8-8-33-JGN-TR (0.031" / 0.80mm) and the other two parts (0.035" / 0.90mm) is within typical PCB assembly tolerances but should be verified against specific board design constraints. All parts share identical electrical parameters, package configuration, and temperature operating range, making them functionally interchangeable for circuit design purposes.

Frequently Asked Questions (FAQ)

Q: Can ECS-122.8-8-33-JGN-TR be used as a direct replacement for 7V-12.288MDHV-T?

A: Yes. Both parts meet identical electrical specifications (12.288 MHz, ±20ppm tolerance, 8pF load capacitance, 100 Ohms ESR) and share the same 4-SMD, No Lead package with 3.20mm x 2.50mm dimensions. The 0.004" (0.10mm) height difference is negligible for standard PCB assembly.

Q: What is the difference between a direct manufacturer equivalent and a parametric equivalent?

A: ECS-122.8-8-33-JGN-TR is a direct manufacturer equivalent, meaning it is designed as an alternative offering from a different manufacturer with identical specifications. STDCRG2-12.288M is a parametric equivalent, meeting all electrical and mechanical requirements but from a different manufacturer series. Both are functionally interchangeable.

Q: Are all three parts compatible with the same PCB layout?

A: Yes. All three parts use identical package configuration (4-SMD, No Lead), footprint dimensions (3.20mm x 2.50mm), and surface mount mounting type. Height variation (0.031" to 0.035") is within standard assembly tolerances.

Q: Which substitute part has the best compliance certifications?

A: ECS-122.8-8-33-JGN-TR carries RoHS3 Compliant status with REACH Unaffected designation, providing the most comprehensive regulatory coverage. The other two parts are RoHS Compliant, meeting standard environmental requirements.

Q: Can these parts be used interchangeably in production?

A: Yes, provided that circuit design and PCB layout accommodate the specified electrical parameters (frequency, load capacitance, ESR) and physical dimensions. All three parts meet these requirements identically.
