Substitute Part Grouping Explanation

The 416F26033ASR qualifies as a direct parametric equivalent to the 416F26033AST based on strict alignment of the following critical parameters:

• Frequency: 26 MHz (identical)
• Frequency Stability: ±30ppm (identical)
• Frequency Tolerance: ±30ppm (identical)
• ESR: 120 Ohms (identical)
• Load Capacitance: Series (identical)
• Operating Mode: Fundamental (identical)
• Operating Temperature Range: -10°C to 60°C (identical)
• Package / Case: 4-SMD, No Lead (identical)
• Physical Dimensions: 0.063" L x 0.047" W, 0.018" max height (identical)
• RoHS and REACH Compliance: ROHS3 Compliant, REACH Unaffected (identical)

The primary distinction is packaging format: the 416F26033AST is supplied in standard packaging, while the 416F26033ASR is supplied in Tape & Reel (TR) format. Both parts are manufactured by CTS-Frequency Controls within the 416 series.

Parameter Comparison

Frequently Asked Questions (FAQ)

Q: Can the 416F26033ASR directly replace the 416F26033AST in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The 416F26033ASR operates at the same 26 MHz frequency with ±30ppm stability, identical ESR of 120 Ohms, and the same 4-SMD, No Lead package dimensions. No circuit modifications are required.

Q: What is the difference between the 416F26033AST and 416F26033ASR?

A: The primary difference is packaging format. The 416F26033AST uses standard packaging, while the 416F26033ASR is supplied in Tape & Reel (TR) format. All electrical and mechanical specifications are identical.

Q: Why is the 416F26033AST discontinued?

A: The 416F26033AST is discontinued at DiGi Electronics. The 416F26033ASR remains in active production and is the recommended substitute for new orders and ongoing applications.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1, Unlimited). Regulatory compliance is equivalent.

Q: What is the operating temperature range for these crystals?

A: Both the 416F26033AST and 416F26033ASR operate across -10°C to 60°C. Frequency stability of ±30ppm is maintained throughout this range.

Q: Is the physical footprint identical between these parts?

A: Yes. Both parts measure 0.063" L x 0.047" W (1.60mm x 1.20mm) with a maximum seated height of 0.018" (0.45mm). PCB layout and assembly processes remain unchanged.
