Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SG-771PCD 100.0000M-A3 is determined by the following critical parameters:

• Frequency: 100 MHz (exact match required)
• Output Type: LVPECL (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable (exact match required)
• Package / Case: 6-SMD, No Lead (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Frequency Stability: ±30ppm or better (equal or tighter tolerance acceptable)

Parts are classified into two categories:

Direct Substitutes (656E10004I3T, 656P10004I3T, SXO75P3B481-100.000M): Meet all critical parameters with identical or superior electrical and mechanical specifications. These parts are functionally interchangeable with the SG-771PCD 100.0000M-A3.

Similar Substitute (626P10005I3T): Meets all critical parameters but differs in physical dimensions (0.098" L x 0.079" W vs. 0.276" L x 0.197" W) and has improved frequency stability (±25ppm vs. ±30ppm). This part is electrically compatible but requires PCB layout verification due to dimensional differences.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (656E10004I3T, 656P10004I3T, SXO75P3B481-100.000M):

All three direct substitutes are active products with ROHS3 compliance. The 656E10004I3T and 656P10004I3T are functionally identical CTS-Frequency Controls parts available in Tape & Reel packaging with 1086 and 798 units in stock respectively. The SXO75P3B481-100.000M from Suntsu Electronics offers the lowest seated height (1.70mm) and highest inventory availability (1719 units) in bulk packaging. All three maintain identical electrical specifications and package footprint to the obsolete SG-771PCD 100.0000M-A3.

Similar Substitute (626P10005I3T):

The 626P10005I3T is an active CTS-Frequency Controls product with improved frequency stability (±25ppm vs. ±30ppm) and identical electrical performance. However, this part features a significantly smaller footprint (2.50mm x 2.00mm vs. 7.00mm x 5.00mm) and lower seated height (1.10mm vs. 1.80mm). Selection of this part requires verification that the PCB layout accommodates the reduced dimensions and that the lower current draw (70mA maximum, matching the original specification) is acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can the 656E10004I3T and 656P10004I3T be used interchangeably with the SG-771PCD 100.0000M-A3?

A: Yes. Both CTS-Frequency Controls parts are direct substitutes with identical electrical specifications, package configuration, and physical dimensions. The primary difference is packaging format (Tape & Reel vs. original specification).

Q: What is the advantage of the SXO75P3B481-100.000M over the CTS alternatives?

A: The Suntsu part offers the lowest seated height (1.70mm) and highest inventory availability (1719 units). Electrical performance and package footprint are identical to the original part.

Q: Is the 626P10005I3T suitable for direct PCB replacement?

A: The 626P10005I3T is electrically compatible but has a significantly smaller footprint (2.50mm x 2.00mm vs. 7.00mm x 5.00mm). Direct PCB replacement is not possible without layout modification. Verify that the reduced dimensions and lower profile (1.10mm seated height) are compatible with your application before selection.

Q: Do all substitute parts meet RoHS compliance?

A: All active substitute parts (656E10004I3T, 656P10004I3T, SXO75P3B481-100.000M, 626P10005I3T) are ROHS3 compliant. The original SG-771PCD 100.0000M-A3 RoHS status is not specified.

Q: What is the frequency stability difference between the original part and substitutes?

A: The SG-771PCD 100.0000M-A3 and all direct substitutes maintain ±30ppm frequency stability. The 626P10005I3T offers tighter tolerance at ±25ppm, which is superior for applications requiring higher frequency accuracy.

Q: Are there packaging format differences among the substitute parts?

A: Yes. The 656E10004I3T and 656P10004I3T are supplied in Tape & Reel format. The SXO75P3B481-100.000M is supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility.
