Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict parameter matching across electrical and mechanical specifications. The following criteria establish equivalence for the 12.85582:

Critical Matching Parameters:

• Frequency: 32 MHz (exact match required)
• Load Capacitance: 10pF (exact match required)
• ESR: 60 Ohms (exact match required)
• Package / Case: 4-SMD, No Lead (exact match required)
• Physical Dimensions: 0.079" L x 0.063" W (2.00mm x 1.60mm) (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Operating Mode: Fundamental (exact match required)

Acceptable Variation Parameters:

• Frequency Stability: ±10ppm to ±20ppm (tighter stability acceptable)
• Height - Seated (Max): 0.018" to 0.020" (minor variation acceptable)
• Packaging Format: Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel® (format variation acceptable)
• RoHS Status: ROHS3 Compliant (compliance maintained)
• MSL Rating: 1 (Unlimited) or Not Applicable (both acceptable)

All identified substitute parts meet these criteria and are confirmed parametric equivalents.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products with ROHS3 compliance and confirmed parametric equivalence to the 12.85582. Selection between substitutes is based on availability, packaging format preference, and supply chain requirements.

EPSON FA-128 Series (FA-128 32.0000MF20X-K0, FA-128 32.0000MF20X-K3, FA-128 32.0000MF20X-K5): These parts offer tighter frequency tolerance (±10ppm) compared to the main part (±20ppm), providing enhanced stability. The three variants differ only in packaging format: K0 and K5 are supplied in Tape & Reel (TR), while K3 is available in Cut Tape (CT) & Digi-Reel®. Inventory availability is significantly higher for K3 (171,654 pcs) and K5 (177,378 pcs) compared to K0 (3,713 pcs). All three maintain ROHS3 compliance and MSL 1 rating.

IQD Frequency Products LFXTAL073170: This part provides equivalent electrical performance with ROHS3 compliance. MSL rating is Not Applicable rather than 1 (Unlimited). Inventory availability is 4,423 pcs. This option is suitable for applications where MSL classification is not a constraint.

All substitute parts are mechanically compatible with the original 12.85582 design, with height variation of 0.002" (0.05mm) maximum, which is within acceptable PCB assembly tolerances for surface mount components.

Frequently Asked Questions (FAQ)

Q: Can FA-128 32.0000MF20X-K0, K3, and K5 be used interchangeably with the 12.85582?

A: Yes. All three FA-128 variants are parametric equivalents with identical electrical specifications (32 MHz, 10pF load capacitance, 60 Ohms ESR, ±10ppm tolerance, -40°C to 85°C operating range) and mechanical compatibility (4-SMD, No Lead package, 2.00mm x 1.60mm dimensions). The variants differ only in packaging format (Tape & Reel versus Cut Tape & Digi-Reel®). Selection depends on assembly line requirements and inventory availability.

Q: What is the difference between the 12.85582 and the EPSON FA-128 series in terms of frequency tolerance?

A: The 12.85582 specifies ±20ppm frequency tolerance, while the EPSON FA-128 series specifies ±10ppm frequency tolerance. The FA-128 series provides tighter tolerance, which is acceptable for applications designed around the 12.85582 specification. Tighter tolerance does not create incompatibility; it represents improved performance.

Q: Is the height difference between the 12.85582 (0.018" max) and substitute parts (0.020" max) significant?

A: The height difference is 0.002" (0.05mm), which is within standard PCB assembly tolerances for surface mount components. This variation does not affect mechanical fit or electrical performance in standard applications. Verify clearance in designs with height-constrained layouts.

Q: Can the LFXTAL073170 be used as a direct replacement for the 12.85582?

A: Yes. The LFXTAL073170 meets all electrical and mechanical specifications of the 12.85582. The primary difference is MSL rating: the 12.85582 is MSL 1 (Unlimited), while the LFXTAL073170 is Not Applicable. This distinction does not affect compatibility in applications where MSL classification is not a procurement requirement.

Q: Which substitute part has the best inventory availability?

A: The EPSON FA-128 32.0000MF20X-K3 has the highest inventory at 171,654 pcs. The FA-128 32.0000MF20X-K5 has 177,378 pcs available. Both are suitable for high-volume production requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts (FA-128 32.0000MF20X-K0, FA-128 32.0000MF20X-K3, FA-128 32.0000MF20X-K5, and LFXTAL073170) are ROHS3 compliant, matching the compliance status of the 12.85582.
