Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1757200000 is determined by the following critical parameters:

• Electrical Compatibility: Pitch (4.6mm), number of positions (22), and current/voltage ratings must support the application requirements
• Mechanical Compatibility: Header orientation (vertical), mounting type (through hole), and shrouding configuration (4-side) must match the PCB footprint
• Termination Compatibility: Solder termination style ensures compatibility with existing assembly processes
• Environmental Compliance: RoHS compliance and flammability rating (UL94 V-0) must be maintained for regulated applications

The substitute part 1729510000 maintains identical mechanical and electrical pin configurations while offering enhanced electrical ratings and extended temperature range, making it a direct functional equivalent despite differences in contact finish and housing color.

Parameter Comparison

Engineering Selection Recommendations

The 1729510000 serves as the active production equivalent for the obsolete 1757200000. Both components share identical mechanical footprints and pin configurations, ensuring direct PCB compatibility. The substitute part provides enhanced electrical performance with higher IEC voltage rating (250V vs. 50V) and extended lower temperature limit (-50°C vs. -20°C), making it suitable for applications requiring broader environmental operating ranges.

Both parts maintain RoHS compliance and UL94 V-0 flammability certification, satisfying regulatory requirements for controlled environments. The 1729510000 is the recommended selection for new designs and replacement applications where the Omnimate S2L 22-position 4.6mm pitch header is specified.

Frequently Asked Questions (FAQ)

Q: Can the 1729510000 be used as a direct replacement for the 1757200000 in existing designs?

A: Yes. Both parts share identical mechanical dimensions, pin pitch (4.6mm), position count (22), and through-hole solder termination. PCB footprints are interchangeable. The substitute part offers enhanced electrical ratings and extended temperature range, making it suitable for the same applications.

Q: What are the key differences between these two parts?

A: The primary differences are product status (obsolete vs. active), electrical ratings (IEC voltage 50V vs. 250V, IEC current 7.5A vs. 10A), operating temperature range (-20°C to 100°C vs. -50°C to 100°C), contact finish (gold vs. tin), housing color (black vs. orange), and ingress protection (none vs. IP10). Mechanical and pin configurations remain identical.

Q: Are there any compatibility concerns when substituting the 1729510000 for the 1757200000?

A: No compatibility concerns exist for standard applications. The substitute part's higher electrical ratings and extended temperature range provide equal or superior performance. Both parts use identical pitch, position configuration, and solder termination. Verify application voltage and current requirements fall within both parts' specifications.

Q: What is the significance of the different contact finishes (gold vs. tin)?

A: Contact finish affects mating durability and corrosion resistance. Gold provides superior corrosion resistance and contact reliability in harsh environments. Tin offers cost efficiency for standard applications. Both finishes are suitable for solder termination and through-hole mounting. Application environment determines the appropriate choice.

Q: Does the IP10 ingress protection rating on the 1729510000 affect compatibility?

A: The IP10 rating on the 1729510000 indicates basic protection against solid objects larger than 50mm. This is an enhancement over the main part and does not create compatibility issues. It provides additional environmental protection without affecting electrical or mechanical interface characteristics.

Q: Are both parts suitable for RoHS-regulated applications?

A: Yes. Both the 1757200000 and 1729510000 are RoHS compliant and carry UL94 V-0 flammability certification, meeting requirements for regulated industries and controlled environments.
