Engineering Selection Recommendations

7302-12-1000 (Preferred Substitute)

The 7302-12-1000 is the direct functional equivalent of the 7302-12-1100. Selection of this substitute is based on the following engineering criteria:

1. Identical Electrical Specifications: All coil, contact, and switching parameters are matched without deviation.
2. Compatible Mechanical Configuration: Both parts utilize identical through-hole PC pin termination, ensuring direct board-level interchangeability.
3. Active Product Status: The 7302-12-1000 maintains active status with Coto Technology, providing current availability and supply security. The main part (7302-12-1100) is classified as obsolete.
4. Regulatory Compliance: Both parts achieve ROHS3 compliance and possess identical moisture sensitivity levels, maintaining design compliance requirements.
5. Series Continuity: Both parts belong to the Coto 7000 reed relay series, confirming design lineage and manufacturing consistency.

When the main part 7302-12-1100 is unavailable due to obsolete status, the 7302-12-1000 provides seamless functional replacement in existing designs requiring no circuit or board modifications.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between the 7302-12-1100 and 7302-12-1000?
