TecDoc OE Parts Data provides precise, regularly updated original equipment (OE) reference information linked to TecDoc vehicle and aftermarket data. Based on in-depth analysis of OE spare parts catalogues (EPCs), it enables reliable matching between OE and aftermarket parts.

By linking OE references and vehicle applications within a standardised data structure, TecDoc OE Parts Data helps businesses to improve parts identification, enhance cross-referencing accuracy, streamline workflows, and support confident part selection across the automotive aftermarket.

Building a competitive product portfolio depends on accurate reference data and a clear understanding of OE relationships. Without reliable OE information, it becomes difficult to identify missing references, manage supersessions, or ensure correct vehicle linkages. This can lead to gaps in the portfolio and delayed market entry. 

TecDoc OE Parts Data provides carefully researched and analysed OE information sourced from official Electronic Parts Catalogues (EPCs) and linked to the TecDoc Standard.  

Within TecDoc, OE data acts as a foundational reference layer. This solid basis ensures that all parts, OE or aftermarket, are accurately represented and matched to specific vehicles. 

By using OE data as a benchmark, manufacturers can validate compatibility, improve data quality, and align their product offerings with real market demands. they can reduce errors and speed up their time-to-market. 

TecDoc OE Parts Data provides a structured and reliable OE reference layer to support product development, portfolio expansion, and data optimisation.

Broad coverage and depth: Access OE parts data across three vehicle segments, 35+ product groups, and 360+ generic articles in seven regions worldwide. This supports both regional and global product strategies.

Accurate OE reference data: Benefit from OE information sourced from official spare parts catalogues (EPCs) and aligned with vehicle manufacturer specifications.

Cross-referencing and vehicle matching: Match OE part numbers to aftermarket equivalents and vehicle applications to provide accurate parts identification and replacement selection.

Product and compatibility analysis: Analyse the compatibility of products with specific vehicle makes and models to improve coverage and support product development decisions.

Portfolio gap analysis: Identify missing OE references, supersessions, and coverage gaps to uncover opportunities for portfolio expansion and optimisation. 

OE Parts Data follows a structured process to ensure accuracy, consistency, and usability: 

1. Data collection: Comprehensive make and model data is gathered for passenger cars, light commercial vehicles, and heavy-duty vehicles. 

2. Analysis: Data is analysed against official EPC systems, ensuring alignment with OE specifications. 

3. Integration: Validated data is standardised and integrated into the TecDoc data model and product database. 

4. Access and use: Manufacturers can access this data to perform: 

• Product analysis → validate compatibility with specific vehicles 

• Gap analysis → identify missing references or incomplete portfolio coverage 

• Cross-referencing → match OE numbers to aftermarket equivalents 

This structured approach enables manufacturers to make informed product decisions and continuously optimise their portfolios. 

Manufacturers using TecDoc OE Parts Data benefit from stronger product strategies, improved data quality, and better market coverage.

Expected outcomes are:

• Faster time-to-market for new products

• Identification of portfolio gaps and expansion opportunities

• Improved completeness and accuracy of vehicle linkages

• Better visibility of OE replacements and supersessions

• Easier tracking of OE part numbers and replacement references

• Better-informed decisions on product range development and market opportunities

By linking product data to OE references, TecDoc OE Parts Data helps manufacturers to identify missing applications, expand product coverage, and maintain accurate, up-to-date portfolio information. This enables them to deliver more complete product ranges that are aligned with vehicle demand and market requirements.
