Review all available part information (MPN, package, pin count, description, properties). If no datasheet URL is already set, search the web for the official datasheet and update the part's Datasheet property with the URL. Then cross-check the schematic symbol, footprint, and pin descriptions against the datasheet. Summarize key specs and flag any mismatches.
I’ll audit the part metadata, locate the manufacturer datasheet if needed, update the Datasheet property, then compare the symbol, footprint, and pin definitions against the official documentation.
Audit complete. The datasheet was already populated and matches the manufacturer’s 0132M4 family sheet, so no URL change was needed; the symbol pin mapping is correct, but Manufacturer Name and pin descriptions are missing, and the footprint geometry substantially differs from the recommended land pattern. I documented the specifications and mismatches in Part Audit Report and filed an internal part-quality report.

The exact suffix clearly encodes 13.52313 MHz and 20 pF. The available family sheet does not provide enough ordering-code detail in searchable text to independently decode every remaining suffix character, so exact tolerance, stability, and operating-temperature grades should be confirmed against the purchase record or a variant-specific certificate.

The symbol has four passive terminals and the pin numbering/function mapping matches the datasheet. However, the terminal Pin Description properties are not populated. Recommended descriptions are “Crystal terminal” for pins 1 and 3 and “Case ground / metal lid” for pins 2 and 4. The two CASE/GND terminals share the same visible name, which is electrically appropriate, but unique pin numbers remain essential and are present.
Footprint cross-check
The current footprint contains four top-layer rectangular pads with the expected pin association. Interpreting the layout values in physical millimeters, the current geometry is approximately:
Pad centers: X = ±0.84 mm, Y = ±1.09 mm
Center-to-center pitch: 1.68 mm horizontally × 2.18 mm vertically
Pad size: approximately 1.09 mm × 1.29 mm
The manufacturer-family drawing found on the web indicates a suggested land pattern of approximately:
Center pitch: 1.3 mm horizontally × 1.2 mm vertically
Pad size: approximately 1.0 mm × 0.5 mm
Mismatch: The current footprint pad pitch and pad dimensions differ substantially from the manufacturer suggested land pattern. The current pads appear especially oversized in one axis and too widely separated. This should be corrected before using the part in production. Pin-1 orientation should also be rechecked after correcting the geometry.
Other mismatches and missing data
Manufacturer Name property missing: Component review flags the project because Manufacturer Name is not set, although the manufacturer is stated in the description and datasheet.
Pin descriptions missing: All four terminals lack explicit Pin Description metadata.
Footprint mismatch: Current pad geometry does not agree with the manufacturer land-pattern drawing.
Height ambiguity: The project description states 3.2 × 2.5 × 0.6 mm, while one accessible package-outline rendering reports 0.8 mm maximum. The manufacturer PDF feature text states 0.6 mm. Treat the exact maximum height as requiring visual confirmation from the authoritative drawing or a variant-specific mechanical specification.
Exact suffix grades not fully verified: Frequency and load capacitance are clear, but exact tolerance/stability/temperature codes were not decoded from the family datasheet text.
Recommended corrections
Set Manufacturer Name to “Suzhou HangJing Elec&Tech Co., Ltd.”
Add terminal descriptions for all four pins.
Redraw the footprint from the manufacturer land-pattern dimensions and verify top-view pin-1 orientation.
Confirm maximum component height and suffix-grade details from the procurement record or a variant-specific datasheet/certificate before release.
