Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7WA0000008 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Requirements:

• Frequency: 100 MHz (exact match required)
• Output: CMOS (fixed requirement)
• Supply Voltage: 3.3V (fixed requirement)
• Function: Enable/Disable (fixed requirement)
• Frequency Stability: ±50ppm (fixed requirement)
• Operating Temperature: -40°C ~ 85°C (fixed requirement)

Mechanical Compatibility Requirements:

• Mounting Type: Surface Mount (fixed requirement)
• Package / Case: 4-SMD, No Lead (fixed requirement)
• Physical Dimensions: 0.276" L x 0.197" W (7.00mm x 5.00mm) (fixed requirement)

All substitute parts listed meet these criteria. Variations in supply current, seated height, and product status are secondary considerations that do not affect functional substitution.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts (510CAA100M000AAGR, CPPC7L-A7BP-100.0TS, OCETGLJTNF-100.000000, and SXO75C3A481-100.000M) are functionally equivalent to the obsolete 7WA0000008 based on electrical and mechanical parameters.

Active Product Status: All substitute parts carry active product status, ensuring ongoing availability and manufacturer support. The original 7WA0000008 is obsolete and no longer manufactured.

Compliance Certifications: Three of the four substitute parts (CPPC7L-A7BP-100.0TS, OCETGLJTNF-100.000000, and SXO75C3A481-100.000M) carry ROHS3 compliance certification. The 510CAA100M000AAGR does not specify RoHS status in the provided data. Three parts (CPPC7L-A7BP-100.0TS, OCETGLJTNF-100.000000) explicitly confirm REACH Unaffected status.

Physical Fit Considerations: All substitute parts maintain the same footprint (0.276" L x 0.197" W / 7.00mm x 5.00mm). Seated heights vary between 0.056" and 0.075" (1.42mm to 1.90mm). The original part height is 0.056" (1.42mm). Substitute parts with greater seated heights (510CAA100M000AAGR at 0.071", CPPC7L-A7BP-100.0TS at 0.075") require clearance verification in height-constrained applications.

Supply Current Considerations: Supply current specifications vary among substitutes (26mA to 65mA). The original part does not specify maximum supply current. Applications with strict power budget constraints should prioritize 510CAA100M000AAGR (26mA) or CPPC7L-A7BP-100.0TS (25mA).

Frequently Asked Questions (FAQ)

Q: Can the 510CAA100M000AAGR directly replace the 7WA0000008?

A: Yes. The 510CAA100M000AAGR meets all electrical and mechanical substitution criteria: 100 MHz frequency, CMOS output, 3.3V supply, enable/disable function, ±50ppm stability, -40°C to 85°C operating range, 4-SMD no-lead package, and 7.00mm x 5.00mm footprint. The part is active and in stock.

Q: What is the difference between the substitute parts?

A: All substitute parts are electrically equivalent. Differences exist in supply current specifications (26mA to 65mA), seated height (0.056" to 0.075"), packaging format (tape & reel versus bulk), and manufacturer. These differences do not affect functional compatibility but may influence selection based on application-specific requirements.

Q: Does seated height variation affect PCB assembly?

A: Seated height differences range from 0.056" (1.42mm) for the original part to 0.075" (1.90mm) for the CPPC7L-A7BP-100.0TS. In applications with minimal clearance above the component, taller substitutes may require design verification. The OCETGLJTNF-100.000000 (0.059" / 1.50mm) and SXO75C3A481-100.000M (0.063" / 1.60mm) present minimal height increase.

Q: Are all substitute parts RoHS compliant?

A: Three of four substitute parts explicitly state ROHS3 compliance: CPPC7L-A7BP-100.0TS, OCETGLJTNF-100.000000, and SXO75C3A481-100.000M. The 510CAA100M000AAGR does not specify RoHS status in the provided data. The original 7WA0000008 is RoHS Compliant.

Q: Which substitute part has the lowest supply current?

A: The 510CAA100M000AAGR (Skyworks Si510 series) specifies 26mA maximum supply current, the lowest among the four substitutes. The CPPC7L-A7BP-100.0TS follows at 25mA. For applications with strict power constraints, these two options are preferred.

Q: What is the difference between tape & reel and bulk packaging?

A: Tape & reel packaging is standard for automated assembly processes and is offered by Skyworks (510CAA100M000AAGR), Cardinal (CPPC7L-A7BP-100.0TS), and Taitien (OCETGLJTNF-100.000000). Bulk packaging is offered by Suntsu (SXO75C3A481-100.000M) and is typically used for manual assembly or lower-volume applications. Packaging format does not affect component functionality.

Q: Can I use the SXO75C3A481-100.000M as a substitute?

A: Yes. The SXO75C3A481-100.000M meets all electrical and mechanical substitution criteria. However, it specifies the highest supply current (65mA) among the substitutes and does not specify current in disable mode. It is suitable for applications without strict power constraints.
