GC2000026 20 MHz Crystal Equivalent & Substitute Parts

Part Overview

The GC2000026 is a 20 MHz fundamental mode crystal manufactured by Diodes Incorporated in the SaRonix-eCera™ GC series. This surface mount device features a 20pF load capacitance, 30 Ohms equivalent series resistance, and operates across -20°C to 70°C. The part is ROHS3 compliant and carries an unlimited moisture sensitivity level rating. Substitute parts are identified when frequency, stability, operating mode, temperature range, mounting type, and package case remain consistent within specified tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the GC2000026 are qualified based on the following critical parameters that must remain constant or within acceptable tolerance:

• Frequency: 20 MHz (exact match required)
• Frequency Stability: ±30ppm (exact match required)
• Operating Mode: Fundamental (exact match required)
• Operating Temperature Range: -20°C ~ 70°C (exact match required)
• Package / Case: HC-49/US (exact match required)
• Mounting Type: Surface Mount (exact match required)

Load capacitance and ESR may vary within the constraints of the application circuit design. The identified substitutes maintain all critical parameters while offering alternative load capacitance and ESR specifications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and meet ROHS3 compliance requirements. The GC2000026 and GC2000032 are both manufactured by Diodes Incorporated within the SaRonix-eCera™ GC series, differing only in load capacitance specification (20pF versus 18pF) and maintaining identical ESR at 30 Ohms.

The ABLS-20.000MHZ-B-4-Y-T from Abracon LLC provides an alternative source with identical frequency, stability, and operating characteristics. This part carries a 40 Ohms ESR specification compared to the 30 Ohms of the primary part, and differs slightly in physical dimensions (11.40mm x 4.70mm versus 11.70mm x 4.80mm). REACH status differs between manufacturers; the Abracon part is REACH Affected while Diodes Incorporated parts are REACH Unaffected.

Selection between these parts depends on circuit design requirements for load capacitance and ESR tolerance, as well as supply chain and regulatory compliance considerations specific to the application.

Frequently Asked Questions (FAQ)

Q: Can GC2000032 directly replace GC2000026?

A: GC2000032 maintains identical frequency, stability, operating mode, temperature range, package, and mounting specifications. The load capacitance differs at 18pF versus 20pF. Direct substitution is possible if the application circuit accommodates the 18pF load capacitance specification.

Q: What is the significance of the ESR difference between GC2000026 and ABLS-20.000MHZ-B-4-Y-T?

A: ESR (Equivalent Series Resistance) affects crystal oscillator circuit performance, including startup time and power consumption. The ABLS part specifies 40 Ohms compared to 30 Ohms for the GC2000026. Circuit design must account for this 10 Ohm difference in ESR tolerance.

Q: Are there physical dimension differences between these parts?

A: GC2000026 and GC2000032 share identical dimensions at 11.70mm x 4.80mm length and width. ABLS-20.000MHZ-B-4-Y-T measures 11.40mm x 4.70mm. All three parts maintain the same 4.20mm maximum seated height. PCB layout and mechanical clearance must accommodate these dimensional variations.

Q: What compliance differences exist between manufacturers?

A: Diodes Incorporated parts (GC2000026 and GC2000032) carry REACH Unaffected status. Abracon LLC's ABLS-20.000MHZ-B-4-Y-T is REACH Affected. Applications subject to REACH regulations must account for this distinction in supplier selection.

Q: Can these parts be used interchangeably in production?

A: Interchangeability depends on circuit design tolerance for load capacitance and ESR variations, physical dimension constraints, and regulatory compliance requirements. Engineering validation is required to confirm compatibility within specific application parameters.
